Abstract:
HighlightsWe provide context and perspectives on articles in the Wetland Ecosystem Resilience collection.Insights gained on wetland resilience to sea-level rise and climate change, land use and drainage, and nutrients. Abstract. The objective of this article is to introduce a collection of articles that explore current research and scientific thought on wetland ecosystem resilience. The collection contains articles on wetland resilience to climate change, agricultural land use-driven change, and recreational land use, along with evaluations of wetland resilience through high-resolution monitoring and modeling tools. Wetland settings in the U.S. span tidal marshes and coastal plain non-riverine wetlands in North Carolina, prairie potholes in Iowa, Appalachian floodplain wetlands, and floating treatment wetlands in the Midwest. The studies in this collection found vertical accretion rates of 0.7 to 4.0 mm year-1 in a tidal marsh, a wide range of potential wetland hydroperiod responses to climate change, substantial decreases in inundation period, crop yield, and surface-water nitrate (but increases in phosphorus) in artificially drained potholes, and nitrate removal in carbon-amended floating treatment wetlands. Further work is needed to better understand how to design and enhance wetland systems in agricultural regions, better preserve wetland ecosystem services in areas affected by land use and climate change, and provide technical standards for the wide range of designs currently used for wetland treatment systems.

Abstract:
Ecosystem services depend on the interrelation between people and the environment, and people are increasingly recognizing the social value of ecosystem services. Based on humans needs related to the values of ecosystem services, riparian greenways, properly planned and managed for resiliency, could provide great opportunities for social ecological change and transformation toward sustainability. We focus on the ecosystem service values of such greenways based on resilience in urban communities. The purpose of this study is to assess the social value of ecosystem services for resilient riparian greenway planning and management based on a survey of residents living near the Yangjaecheon riparian greenway in Gwacheon, South Korea. First, cluster analysis was performed with data from 485 completed surveys to identify different groups of respondents. Importance-performance analysis (IPA) was then applied to develop planning and management guidance for the riparian greenway based on group characteristics. Two distinct groups were identified: the Strong Social Value of Ecosystem Services group and the Neutral Social Value of Ecosystem Services group. Different distributions were found between the two groups based on gender and residency period, and significant differences were also found for age and familiarity with the riparian greenway. The results show what each group perceived to be important and how well the riparian greenway met their expectations regarding ecosystem services. These results indicate the perceived value of ecosystem services on the basis of the group characteristics, helping establish the direction for resilient riparian greenway planning and management approaches.

Abstract:
This research was conducted to assess the social and ecological resiliences of mangrove ecosystem to sea level rise as a consequence of climate change. Resilience Index (RI) method was used range from 0 to 1. Sixteen resilience indicators, both ecological and social, are selected, developed, and evaluated. The indicators consist of mangrove coverage, density and diversity, aquatic fauna species, tidal flooding, salinity, sedimentation, land use, mangrove dependency and time allocation, conflicts potential, knowledge, the compliance rate, types of livelihood, institution cap, and level of education. Evaluation result indicate that the bay was divided into two categories of resilience; the majority has middle resilience because the mangrove coverage, density, and land use are high, with composite RI (CRI) range from 0.45 to 0.58. This was found in the villages of Muara, Langensari, Blanakan, Jayamukti, and Rawameneng. Only one village has high CRI of 0.69, such as the Cilamaya Girang. The main ecological factors that contribute to the high resilience of the area is the rate of sedimentation of 2 meters per year and rare tidal flooding, while the factor that contributes most to the impediment of social resilience is public knowledge about the importance of mangrove ecosystems©Penelitian ini merupakan penilaian parameter resiliensi ekologis-sosial ekosistem mangrove terhadap penaikan muka air laut sebagai konsekuensi dari perubahan iklim. Analisis yang dilakukan adalah untuk menghitung indeks resiliensi (Resiliency Index/RI) yang menggunakan skala 0-1. Enam belas parameter (ekologis-sosial) digunakan dalam penelitian ini, yaitu: penutupan, kerapatan, keanekaragaman jenis mangrove, jenis fauna akuatik, salinitas, banjir pasang, penggunaan lahan, laju sedimentasi, ketergantungan masyarakat, alokasi waktu pemanfaatan ekosistem mangrove, potensi konflik, tingkat kepatuhan masyarakat, pemahaman fungsi mangrove, jenis mata pencaharian, kelembagaan, dan tingkat pendidikan. Hasil analisis RI menunjukkan, Teluk Blanakan hanya memiliki 2 tingkat resiliensi, yaitu Tingkat Menengah dan Tingkat Tinggi. Tingkat Menengah memiliki penutupan mangrove yang rendah, kerapatan mangrove yang rendah, dan ketergantungan pemanfaatan mangrove yang sangat tinggi dengan kisaran nilai RI 0.45-0.58 yang ditempati oleh Desa Rawameneng, Jayamukti, Blanakan, Langensari, dan Muara. Tingkat Tinggi dengan nilai RI 0.69 hanya ditempati oleh Desa Cilamaya Girang, karena memiliki laju sedimentasi dan ketergantungan masyarakat terhadap kawasan mangrove yang rendah©

Abstract:
Sustainable conservation aims to ensure the sustained conservation of landscape multi-functionality which in turn requires ensuring ecosystem service (ES) and habitat quality (HQ) sustainability with inclusive landscape-scale conservation planning. This study proposes a landscape conservation planning (LCP) framework for landscape-scale ES-HQ conservation and sustainability. Spatially explicit hotspots for five ESs and HQs are identified via InVEST and LISA software. Spatiotemporal changes in ES-HQ hotspots, in terms of stability and resilience, are delineated. The Zonation technique is applied to prioritize areas for conservation based on ES-HQ hotspot stability and resilience maps. High priority conservation areas are identified and are used as reserve area inputs for land use modeling with CLUE-S software to simulate future land use change under climate change scenarios. This study reports that varied rainfall and climate are major driving factors of ES-HQ sustainability disturbance in the study area. Furthermore, our proposed conservation Strategy 2 demonstrates that a larger extent of landscape multi-functionality can be sustained when the existing conservation area includes the total area of identified ES-HQ resilient hotspots. This study effectively identifies the stability and resiliency of ES-HQ hotspot areas affected by disturbances for high priority landscape conservation requirements to ensure ES-HQ sustainability and landscape multi-functionality in the study area.

Abstract:
Nature-based solutions (NbS) build upon the proven contribution of well-managed and diverse ecosystems to enhance resilience of human societies. They include alternatives to techno-industrial solutions that aim to enhance social-ecological integration by providing simultaneous benefits to nature (such as biodiversity protection and green/blue space) and society (such as ecosystem services and climate resiliency). Yet, many NbS exhibit aspects of a technological or engineered ecosystem integrated into nature; this techno-ecological coupling has not been widely considered. In this work, our aim is to investigate this coupling through a high-level and cross-disciplinary analysis of NbS for water security (quantity, quality, and/or water-related risk) across the spectrums of naturalness, biota scale, and benefits to nature and society. Within the limitations of our conceptual analysis, we highlight the clear gap between “nature” and “nature-based” for most NbS. We present a preliminary framework for advancing innovation efforts in NbS towards maximizing benefits to both nature and society, and offer examples in biophysical innovation and innovation to maximize techno-ecological synergies (TES).

Abstract:
Freshwater ecosystems and the fisheries they support are increasingly threatened by human activities. To aid in their management and protection, we outline nine key principles for supporting healthy and productive ecosystems based on the best available science, including laws of physics and chemistry apply to ecology; population dynamics are regulated by reproduction, mortality, and growth; habitat quantity and quality are prerequisites of fish productivity; connectivity among habitats is essential for movements of fishes and their resources; freshwater species and their habitats are tightly linked to surrounding watersheds; biodiversity can enhance ecosystem resiliency and productivity; global processes affect local populations; anthropogenic stressors have cumulative effects; and evolutionary processes can be important. Based on these principles, we provide general recommendations for managing and protecting freshwater ecosystems and the fisheries they support, with examples of successful implementation for each strategy. Key management strategies include engage and consult with stakeholders; ensure that agencies have sufficient capacity, legislation, and authority to implement policies and management plans; define metrics by which fisheries resources and management success or failure will be measured; identify and account for threats to ecosystem productivity; adopt the precautionary approach to management; embrace adaptive management; implement ecosystem-based management; account for all ecosystem services provided by aquatic ecosystems; protect and restore habitat as the foundation for fisheries; and protect biodiversity. Ecosystems are complex with many intertwined components and ignoring linkages and processes significantly reduces the probability of management success. These principles must be considered when identifying management options and developing policies aiming to protect productive freshwater ecosystems and sustainable fisheries.

Abstract:
River watersheds are among the most complex terrestrial features in Alaska, performing valuable ecosystem functions and providing services for human society. Rivers are vital to both estuarine and aquatic biota and play important roles in biogeochemical cycles and physical processes. The functions of watersheds have been used as vulnerability indicators for ecosystem and socioeconomic resilience. Despite a long history of human activity, the Yukon River has not received the holistic and interdisciplinary attention given to the other great American river systems. By using hypothesis-based monitoring of key watershed functions, we can gain insight to regime-shifting stresses such as fire, toxins, and invasive species development. Coupling adaptive risk management practices involving stakeholders with place-based education, especially contaminants and nutrition related, can maintain resilience within communities. The Yukon watershed provides a broadscale opportunity for communities to monitor the environment, manage resources, and contribute to stewardship policy formation. Monitoring keystone species and community activities, such as citizen science, are critical first steps to following changes to resiliency throughout the Yukon watershed. Creating a policy environment that encourages local experimentation and innovation contributes to resilience maintenance during development-imposed stress.

Abstract:
Introduced in ~59 countries and native across Europe and Asia, wild pigs, Sus scrofa, are the most wide-spread swine species in the world. As ecosystem engineers, wild pigs are a significant source of disturbance in introduced ecosystems due to their numerous, complex impacts on ecosystem processes. Wild pigs are often found in the resource-rich habitat of coastal forests. Coastal forests are complex, dynamic systems with tremendous biodiversity. Exposed to recurrent disturbances, the biophysical characteristics of coastal forests contribute to their ability to return to their original state post-disturbance. However, compounding disturbances can weaken this ability and threaten the health and function of the ecosystem. In this review, through the model of the forests of the southeastern United States Coastal Plain, we (1) describe conditions found across the forested coastal landscape, (2) describe wild pig disturbance, and (3) discuss how wild pig impacts can add to significant anthropogenic and climate-related disturbances threatening coastal forests. Through this review, we find that the impacts of wild pig disturbance on coastal forests often have similar effects as anthropogenic and climate change-related disturbances that may enhance these significant threats to coastal forest function and resiliency.

Abstract:
Accelerated sea-level rise and increased intensity of tropical storm events have challenged the conventional approaches to conservation and restoration of coastal ecosystems. In coastal communities, where survival will depend largely on the ability of species to adapt to rapidly shifting conditions or become established farther inland, historic assemblages may be lost. Seed banks may be an important component of resilience and recovery in response to altered inundation regimes, should they contain species able to adapt or migrate inland. This study assess the ability of seed banks to act as ecological buffers to storm surge disturbances and to instill ecological resilience in degraded and vulnerable coastal ecosystems. Above-ground, seed bank and propagule assemblages were surveyed from historic communities at the Grand Bay National Estuarine Research Reserve. Artificial storm surge experiments revealed that that seed banks were not well distributed throughout the coastal transition communities and that seed bank responses following storm surges are likely to vary among the different plant communities. While some relict species are expected to respond following disturbances, ruderal species are especially dominant in the upland seed bank communities and may, at least in the short term, cause shifts away from the historical assemblages. The apparent absence of seaward species in the upland seed banks may make assisted migration an important tool for the survival of communities unable to keep pace. Community response following translocation of propagule bank application onto highly degraded buyout properties suggested that this technique may be an effective tool in introducing resilience into ecosystems already experiencing the effects of climate change. They resulted in the establishment of diverse and variable communities, containing indicator species from a number of historic communities with varying environmental tolerances. Long-term monitoring of community change and reproductive output of target species may indicate the utility of community translocation in creating resilient and future-adapted communities.

Abstract:
In the northeastern Gulf of Mexico, relating changes in zooplankton communities to environmental factors is crucial to understanding the marine ecosystem and impacts of perturbations such as oil spills on marine ecosystems. Zooplankton samples were collected each year between 2005–2014 in spring and summer in the vicinity of the oil spill (Deepwater Horizon) that occurred in spring 2010. Zooplankton assemblages and environmental conditions significantly differed seasonally, driven by strong variations in zooplankton at continental shelf stations, and by environmental factors including Mississippi River discharge, wind direction, temperature, and chlorophyll concentrations. Total zooplankton abundances were greatest at shelf stations, intermediate at slope stations, and lowest at offshore stations. Seasonal separation was driven by greater abundances of crab zoea, cladocerans, ostracods, and the copepod, Eucalanus spp. during summer. Copepods, Centropages spp., were significant indicators of summer conditions both before and after the oil spill. Sub-regional comparisons in percent composition and abundances of six major non-copepod and seven copepod taxa revealed that most taxa either remained the same or significantly increased in abundance following the spill. A significant decrease in post oil spill taxa was observed only during spring for total copepods, Eucalanaus spp., and for salps at continental slope stations, however varying processing techniques used for zooplankton before and after the spill were employed and should be considered. . Based on our sampling periods, these results indicate that the 2010 oil spill did not significantly impact zooplankton communities in the northeastern Gulf of Mexico.

Abstract:

Deforestation in the Congo Basin is altering the natural functioning and services of the ecosystem and adversely impacting highly vulnerable human populations who rely on their proper functioning. There is currently no framework that comprehensively addresses the historical and cultural complexities that are persistent in Central African societies and that also include, from a micro scale, the detailed voices of local communities. Without such a holistic framework, it is difficult to evaluate the effectiveness or harmfulness associated with current management strategies in responding to deforestation at the various levels. This transdisciplinary mixed method study determined the most salient indirect and direct causes of forest loss, the impacts resulting from an altered state, and the effectiveness of current management responses by assessing changes in forest cover, forest provisions, and trends in forest management. Because forests are common goods, the elasticity of forests are dependent on a multitude of human activities and attitudes. Therefore, data collected via survey tools were used to evaluate the role of multiple stakeholders in the state of the Congo Forest using the Driver-Pressure-State-Impact- Response (DPSIR) framework, a structured analytical tool created by the European Environmental Agency for better understanding of Integrated Environmental Assessments. To best explore local to international perspectives on the effectiveness of current strategies in sustaining forests for livelihoods and ecosystem services, research methods included conducting remote sensing analysis of Landsat satellite images, interviewing over 325 individuals living in 25 communities in the Lake Télé-Lake Tumba Landscape of northwestern Democratic Republic of Congo and 20 individuals working on forest management, conservation, and funding, and a climate analysis using 40 years of weather data collected from a scientific reserve located within the landscape. Results highlight that local populations are highly environmentally literate and their knowledge is a useful tool for qualifying environmental changes, such as reduced lake health, animal health, and plant health. Remote sensing results show the forest is in a state of decline and climate findings confirm the ecological health of the landscape has been reduced demonstrated by major shifts in the traditional agricultural calendars and the effects are having adverse public health impacts on local communities. The process of this research itself interfaces science and policy and thus recommendations focus on how to make effective payments to communities for supporting alternative livelihoods in order to prevent deforestation while next steps should focus on the implications of forest loss and the promotion of a One Health approach at the landscape level.

Abstract:
This research examines the healthcare services ecosystem and the impact and role service interventions made by providers and patients have on this ecosystem. Each area has an important role in contributing to the value and sustainability of the ecosystem. Healthcare, as a community service, requires a minimum of two counterparts: the providers and the customers, in this case the patients. Healthcare is a unique ecosystem because often the customers are not conscious of the interplay of the ecosystem but are reliant upon the system for their health and wellbeing. The first section of this dissertation examines the effects that occur in the healthcare ecosystem when part of the system experiences a disaster and the impact and role of other areas of the system in response to the disaster, particularly regarding the resilience. Similar to a biological ecosystem that is undergoing a flood, in the healthcare services ecosystem if too many patients present to the Emergency Department (ED) at the same time disaster level overcrowding will occur. We aim to measure the resilience of the healthcare ecosystem to this disaster level overcrowding. The second section of this dissertation examines how the components of the healthcare ecosystem maintain sustainability and usability. Healthcare professionals are assessed regarding their ability to maintain the healthcare ecosystem, with a specific focus on what occurs after patients are in the hospital system. To examine the ability of the healthcare professionals to maintain the ecosystem we analyze the usability and adaptability of the electronic health record and the professional's workflows to determine how they use this tool to sustain the healthcare ecosystem. The third section of this dissertation examines patient self-management and the influence this has on the healthcare ecosystem. Much of the management of health in patients, particularly those with chronic illnesses, occurs outside of the hospital, thus examining this aspect of self-care provides insight on the overall system. This research examines patients with a chronic illness and their use of online health communities, with a particular focus on their reciprocal behaviors and the impact this support system has on their overall health state. By examining these aspects of the healthcare services ecosystem, we can better improve our understanding of these phenomena.

Abstract:
Consideration of scale and ecosystem resilience is integral to any conceptual model of the effects of disturbance on ecosystems. Organisms, populations, communities, and ecosystems are differentially affected by disturbance based on the scale at which they occupy the landscape. Scale of observation influences perceptions about ecosystem resilience. There is no single correct scale at which ecological phenomena should be studied, and management decisions require the interfacing of phenomena that occur on very different scales of space and time. Fire disturbance affects a variety of ecosystem factors including nutrient cycling, species diversity, and population and community dynamics. My experimental research on fire in shortgrass steppe examined the effects of fire and season of fire on various components of shortgrass steppe at multiple spatial and temporal scales and organizational units. My experimental design was completely randomized, with 3 treatments, and 4 replicates per treatment. Treatments were dormant-season fire, growing-season fire, and unburned. Response variables were (1) ground cover; (2) microbiotic crust nitrogen fixation, and chlorophyll a content; and (3) species richness, abundance, and relative abundance of small mammals and arthropods. Microbiotic crust cover never differed significantly among treatments for all periods, however, acetylene reduction and chlorophyll a content of crusts differed significantly among treatments. Dormant-season fire-treated crusts had significantly lower rates of acetylene reduction than unburned crusts, while growing-season fire-treated crusts did not differ significantly from unburned or dormant-season fire-treated crusts. Dormant-season fire-treated crusts had significantly lower chlorophyll content than unburned crusts, while growing-season fire-treated crusts did not significantly differ from unburned or dormant-season fire treated-crusts. Initially, growing-season fire significantly reduced grass cover compared to unburned and dormant-season fire. Approximately 30 months later there were no significant differences in grass cover among treatments. Bare ground response was basically the inverse of grass cover response. The only significant differences in litter cover between treatments occurred immediately after the growing-season fire. Arthropod species richness differed significantly among treatments; growing-season fire plots had a significantly higher number of beetle species. However, overall beetle abundance did not significantly differ among treatments. Significant differences were never detected in overall rodent species richness or abundance among treatments.

Abstract:
Our world is subjected to a panoply of drivers of change. In this context, the understanding on how our biosphere resists, absorbs or is altered by the changes, appears as a hot question in ecology. In this respect, two ecological concepts appear as essential, resilience and biotic interactions. Resilience is related to how ecosystems persist under stress or suffering disturbances. Interactions among species are to a large part responsible for the delivery of ecosystem functions, and form the architecture of biodiversity. Moreover, a substantial part of ecosystem resilience is founded on species interactions. This thesis is an attempt to shed some light on these issues through the deep exploration of specific case studies in seagrass ecosystems, in particular how seagrasses respond to external drivers (or how resilient they are), how these responses affect species interactions and which mechanisms allow coexistence of species linked by positive and negative interactions. Our approach is based upon field observations and field manipulative experiments. Chapter 1 shows how an increase of organic matter in sediment weakens the mutualism between the bivalve Loripes lucinalis and the seagrass Cymodocea nodosa. The mechanism implied is the effect of this increase (and, probably, the resulting anoxia) on seagrass root morphology (plant trait), which results in a lower provision of habitat for the bivalves, whose abundance decreases. The weakening of the mutualism can potentially decrease the resilience of these ecosystems to eutrophication and, therefore, compromise their persistence. Chapter 2 describes a facilitative cascade in which the seagrass C. nodosa favors the abundance of the pen shell Pinna nobilis, which positively affects the sea urchin Paracentrotus lividus, which in turn consumes the seagrass. We suggest that the persistence of this three-species assemblage rests on the very local impact of sea urchins on the seagrass, likely driven by behavioural and denso-dependent processes. Chapter 3 and 4 show that fast-growing species such as C. nodosa are highly resilient to stress or disturbances when affecting only the aboveground parts, recovering fast (within two weeks) from a single event of disturbance. C. nodosa shows several mechanisms of tolerance, such as compensatory growth, reallocation of internal resources and enhancement of the formation of new modules, when coping to repeated defoliation simulating herbivory. However, when the belowground parts are lost by disturbances, recovery is highly delayed up to two years and is dependent on the characteristics of the disturbance such as size and timing. Overall, this research has contributed to increase our understanding on how ecosystems respond to changes and how species interactions are maintained and disrupted. We have shown that environmental changes can alter the functioning of seagrass ecosystems at least in two directions. Firstly, by altering fundamental biological interactions, such as the seagrass-lucinid mutualism and, secondly, by affecting the resilience of ecosystems dominated by a foundation species, which promote species coexistence. Advances in the two complementary and interlinked directions will be crucial to better manage and preserve ecosystems and prevent their potential collapse under the increasing human-induced change the world is submitted to.
El nostre món està sotmès a un ampli ventall de forces que tendeixen a provocar canvis. En aquest context, entendre com la biosfera resisteix, absorbeix o és alterada per aquestes forces resulta una qüestió candent, especialment per l'ecologia. Al respecte, dos conceptes ecològics esdevenen essencials: la resiliència i les interaccions biològiques. La resiliència és la capacitat de persistència o recuperació que tenen els ecosistemes sotmesos a estrès o pertorbacions. Les interaccions entre espècies (efectes de l'existència d'una espècie sobre la fitness d'una altra) contribueixen al manteniment de les funcions ecosistèmiques i, en un cert sentit, constitueixen l'arquitectura de la biodiversitat. A més, la resiliència dels ecosistemes depèn , en gran part, d’aquestes interaccions. Aquesta tesi és un intent d’aprofundir en els aspectes esmentats a través d'una sèrie de casos d’estudi en ecosistemes d’angiospermes marines. Concretament, el que fem és estudiar com els ecosistemes d’angiospermes marines responen a les forces causants de canvis, com aquestes respostes vénen mitjançades per canvis en la interacció entre espècies, i provar d'esbrinar els mecanismes que permeten la coexistència d’espècies que es troben vinculades per interaccions positives i negatives. La nostra aproximació es basa tant en observacions com en experiments en el camp. El Capítol 1 mostra com un increment de matèria orgànica en el sediment debilita el mutualisme entre el bivalve Loripes lucinalis i l’angiosperma marina Cymodocea nodosa. El mecanisme implicat que es proposa per explicar-ho està relacionat amb la plasticitat morfològica de la planta. Així, un increment en la matèria orgànica del sediment (i, probablement, l’anòxia que se'n segueix), fa que la planta modifiqui la morfologia de les seves arrels, que esdevenen molt menys ramificades i fan disminuir per tant la disponibilitat d'hàbitat per als bivalves. Una debilitació del mutualisme pot, potencialment, disminuir la resiliència d’aquests ecosistemes a l’eutrofització i, per tant, comprometre la seva persistència. El Capítol 2 descriu una cascada de facilitació en la qual l’angiosperma marina C. nodosa afavoreix l’abundància del gran bivalve Pinna nobilis, que ajuda a incrementar l'abundància de la garota Paracentrotus lividus, que al seu torn consumeix l’angiosperma. Suggerim que la persistència d’aquest sistema de tres espècies, aparentment inestable (tres interaccions concatenades circularment, dues de positives i una de negativa) es basa en què la interacció negativa (l’efecte de les garotes sobre l’angiosperma) té un abast molt limitat, probablement degut tant al seu comportament alimentari com a les defenses de la planta enfront de l'herbivorisme. Els Capítols 3 i 4 mostren que les espècies de creixement ràpid, com ara C. nodosa, són altament resilients a l'estrès o a les pertorbacions quan aquestes afecten només les parts aèries de les plantes (defoliació parcial o total), recuperant-se ràpidament (dues setmanes) després d'una pertorbació puntual en el temps. C. nodosa mostra diversos mecanismes de tolerància a la defoliació, com ara el creixement compensatori, la reassignació de recursos interns i l’increment en la taxa de formació de nous mòduls. Tanmateix, quan les pertorbacions provoquen la pèrdua de les parts subterrànies (rizomes i arrels), la recuperació és molt més lenta, i triga fins a dos anys. A més, aquesta recuperació depèn de les característiques de la pertorbació com ara la mida de l'àrea afectada i l’època de l'any en què es produeix. En general, aquesta tesi ha contribuït a comprendre millor les respostes dels ecosistemes als canvis. Hem pogut documentar alguns processos que permeten la coexistència entre espècies, així com mecanismes de resiliència específics que esdevenen ecosistèmics quan es manifesten en espècies fundadores d'hàbitat. També hem demostrat com els canvis, més enllà d'afectar espècies individuals més o menys emblemàtiques, poden provocar alteracions de formes més subtils, com ara erosionant la seva resiliència mitjançant la modificació d’interaccions biològiques. Els avenços en totes aquestes direccions complementàries i interrelacionades són crucials per a gestionar i preservar els ecosistemes i evitar el seu possible col·lapse.

Abstract:
A model for ecological resilience of Amazonian ecosystems was developed integrating processes such as atmosphere-biosphere coupling with disturbance factors such as fire and climate change. The focus of the study was on the status of ecosystems in the state of Mato Grosso and the possibility of forest to savannah transition was examined using remote sensing data. There was a consistent reduction in EVI during the dry season in Mato Grosso – May through August of each year. The 2005 drought demonstrated a greater dry-season reduction in EVI than normal and there was also a higher frequency of fires (48, 682) than in 2006 (28, 466). There was an increase in fires with distance from the major highways – which is contrary to the results of previous studies. It was estimated that there was a reduction in the amount of forest ecosystems from 2001 to 2006.
Un modèle de résilience écologique de l'écosystème amazonien a été développé, intégrant des processus tels que le couplage atmosphère-biosphère avec des facteurs de perturbation tels que le feu et les changements climatiques. L'objectif de cette étude était d'évaluer l'état des écosystèmes dans l'état du Mato Grosso. Une possible transition de la forêt à la savane a été examinée en utilisant des données de télédétection. Il y a eu une réduction de l'EVI pendant la saison sèche dans le Mato Grosso, de mai à août pour chaque année d'étude. La sécheresse de 2005 a provoqué une réduction de l'EVI plus importante que la normale, en plus d'augmenter la fréquence des feux (48, 682) par rapport à 2006 (28, 466). Il y a eu une augmentation des incendies avec la distance par rapport aux principales autoroutes, ce qui est contraire aux résultats des études précédentes. Il a été estimé qu'il y a eu une réduction du nombre d'écosystèmes forestiers entre 2001 et 2006.

Abstract:
Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. Aware of the global biodiversity loss, ecologists have started identifying the relationship of diversity and ecosystem functioning. Central to this is the question if species can functionally replace other species, hence being functionally redundant. Functional redundancy might allow communities to maintain functioning when diversity is lost. Due to their large numbers and great diversity, bacterial communities have been suspected to harbor large amounts of redundancy. The central aim of this thesis is to investigate the coupling of diversity and ecosystem functioning of bacterial communities and to understand how environmental perturbation affects this relationship. I manipulated the diversity of complex communities by a dilution technique, and measured the performance of bacterioplankton and biofilm-forming communities at different diversities. Reduction of bacterial diversity differently affected different functions, and that the presence or absence of certain species might be causing this pattern. However, for ecosystems to function, the interplay of multiple functions, i.e. multifunctionality, has to be sustained over long periods of time. In bacterial biofilm communities reduced diversity affected multifunctionality, as reflected by extracellular enzyme activities. A continuous cultivation system was used to address the importance of diversity for resistance and resilience upon environmental perturbation. The analysis of co-occurrence of bacterial taxa showed that the communities form a dense network before the perturbation and that these patterns are disturbed by the environmental perturbation. The final chapter of the thesis presents experimental evidence for the positive effects of temporal and spatial refuges for bacterial communities and the functions they provide. Overall, I found several indications for a lower amount of functional redundancy as previously assumed and it becomes apparent from this thesis that a multifunctional perspective and the consideration of environmental heterogeneity is pivotal.

Abstract:
Abstract The concept of resilience has gained momentum during the current climate change era. Resilience is said to be the measure of the amount of change the system can undergo while still retaining the same controls on function and structure. Taking into account the effects of changing climate, the term resilience has been used to assess the vulnerability of social-ecological systems. Most agroecosystem studies have focused on dryland ecosystems and this prompted the need to shift concern on to mountainous ecosystems whose susceptibility to climate change is not adequately addressed. This chapter assesses the resilience of maize-coffee-banana agroecosystems on the southern slope of Mount Kilimanjaro in Tanzania. Also, it assesses agronomic practices and the social-economic status of farmers and computes a social-ecological vulnerability index for the ecosystem. The study depicts variation of agronomic practices with altitude due to microclimatic differences, terrain and soil characteristics that determine the type of crops and their farming system which have both positive and negative implications. Climatic shocks (e.g. drought frequency, floods and below average rains) were found to have an impact on agricultural yield. Social-economic indicators (e.g. the number of household dependants, social safety nets, off-farm contribution, possession of land title, usage of wood for cooking energy and access to extension services) have also shown a significant influence on household vulnerability to changing climate which may later affect the agroecosystem productivity as these parameters are associated with the natural environment. Indicators chosen for the vulnerability index depict slight variations of vulnerability altitude wise, except for the mid-lower zone which appears to be more vulnerable.

Abstract:
Abstract Systems of Systems (SoS) combine complex systems such as financial, transportation, energy, and healthcare systems to provide greater functionality. A failure in a constituent system, however, can render the entire SoS ineffective by causing cascading faults. One method to prevent constituent faults from compromising SoS performance is to increase the SoS’s “resilience,” a measure of the SoS’s ability to cope with these faults and efficiently recover. Attempts to engineer improved resilience require a metric to measure resilience across different SoS architectures (network arrangements). In a previous work, the System of System Resilience Metric (SoSRM) was presented as a possible solution, but this new metric requires additional testing. This work examines the key question: “How can natural ecosystem characteristics be used to validate the SoSRM metric?” We hypothesize that the analysis of a test bed of generic ecosystems will produce SoSRM values that will positively correlate with a triangular trophic structure (wide base), validating SoSRM as a useful design metric. First principles for test bed creation are presented including biodiversity, trophic structure, and the role of detritus. SoSRM is measured for 31 case studies in a trophic structure test bed. Ecosystem network structure is quantified with graph theory. SoSRM correlates as expected with ecosystem network structure (r2 = .5016, n = 31), thus providing a validation of SoSRM as a design tool. As a final check, tests are conducted to ensure SoSRM is independent of trivial network characteristics (i.e. the number of nodes or links). By validating SoSRM, we provide a foundation for future work that focuses on increasing SoS resilience with biologically inspired design heuristics.

Abstract:
Abstract Circular economy aims to address limited resources through the continuous circulation of materials and energy. Recirculating low quality materials for reuse is a sustainability goal that is analogous to the primary function of Nature’s detritus species, a keystone for the proper functioning of ecosystems. Prior applications of ecosystem structure to human network design uncovered that even the most economically successful networks of industries demonstrate a lack of analogous detritus actors in the form of reuse and recycling. The recycling industry’s volatile nature, dependency on international factors, and financial difficulties prevent this strategy from becoming an efficient alternative. Creativity in design, inspired by ecosystems, is proposed here as a method to repurpose manufacturing byproducts that are otherwise seen as low quality waste materials. Realizing the reuse potential of these materials can create detrital-type feedback loops, an attribute that supports the characteristic resilience and efficiency of ecosystems. The work here analyzes existing methods of pursuing circular economy and investigates the potential benefits generated by purposefully adding connects that create detrital-feedback-loops at the consumer and producer levels.

Abstract:
Abstract The objective of this study is to investigate the value of an ecologically inspired architectural metric called the Degree of System Order in the System of Systems (SoS) architecting process. Two highly desirable SoS attributes are the ability to withstand and recover from disruptions (resilience) and affordability. In practice, more resilient SoS architectures are less affordable and it is essential to balance the trade-offs between the two attributes. Ecological research analyzing long-surviving ecosystems (nature’s resilient SoS) using the Degree of System Order metric has found a unique balance of efficient and redundant interactions in their architecture. This balance implies that highly efficient ecosystems tend to be inflexible and vulnerable to perturbations while highly redundant ecosystems fail to utilize resources effectively for survival. Motivated by this unique architectural property of ecosystems, this study investigates the response to disruptions vs. affordability trade-space of a large number of feasible SoS architectures. Results indicate that the most favorable SoS architectures in this trade-space share a specific range of values of Degree of System Order. This suggests that Degree of System Order can be a key metric in engineered SoS development. Evaluating the Degree of System Order does not require detailed simulations and can, therefore, guide the early stage SoS design process towards more optimal SoS architectures.

Abstract:
Abstract Prior work investigated the use of biological food webs as a source of quantitative guidance to balance the efficiency and redundancy in industrial water distribution networks. Urban water distribution networks, however, present unique challenges that prevent a direct replication of the bio-inspired methods used for industrial network settings. Many of the benefits bio-inspiration can impart on human networks, including resilience-related improvements, makes use of reuse- and recycling-related pathways — maximizing the use of all available value in the network. This work looks at the application of bio-inspiration to urban water network settings, modeling these networks to include local wastewater treatment options and testing actor aggregation options to best fit the ecosystem analogy. The results suggest that biological ecosystems do in fact have characteristics that can be beneficial to urban water distribution, but a change of system boundaries is required to recognize their potential.

Abstract:
Simply understood as ‘seeking opportunities out of crises’, resilience seems to be a universal approach to cope with contemporary global challenges, such as changing climate, rapid urbanisation, loss of biodiversity, migrations, etc. As a majority of the current problems are of urban origin – i.e. they emerge in cities, where they also cause significant consequences on people, ecosystems and infrastructures, it is a city and its territorial sub-elements (district, neighbourhood, site, and building) that provide a prolific field for exploring the mechanisms towards resilient governance, planning and design. Under such an overarching agenda of urban resilience, in this paper, we focus on exploring the components of architectural and urban design as a tool for mitigating climate change. More precisely, as carbon dioxide emitted from the built environment is released into the atmosphere at an unprecedented rate, we explore the design patterns that help reduce CO2 emissions to finally lessen the vulnerability index of urban systems. Scrutinising the relationship between the climate change and construction industry, we elucidate the concepts like sustainable construction, green buildings, and design for climate, among others. Finally, through the assessment of the adaptive reuse project in London, this paper identifies strategies of sustainable architectural and urban design aimed at curbing the effects of climate change and helping increase urban resilience.

The leveraging of digital technologies at the intersection of architecture and urbanism allows for imagining scenarios for the future of cities. In line with recent cross-disciplinary research, this paper aims at investigating how large-scale prototyping applied to urban space can generate impact and provide a working model for Resilient Strategies. DATAField, a placemaking intervention developed in New Orleans, investigates how the synthetic integration of ‘the making’ of place, the importance of citizens’ engagement and the incorporation of digital technologies can provide an operative framework for large scale urban prototyping. Introducing models for urban hydrology management, citizen-engaged science, visualization strategies of underlying infrastructural systems and resultant urban prototyping related to resiliency, DATAField demonstrates how digital technologies implemented through systemic approaches can be a powerful tool to design in soft-land and to strengthen citizens’ awareness of ‘how we can live with water’ in vulnerable ecosystems.

Abstract:
Ecology has acted as a source for sound design principles and studies of ecosystems have examined how ecological principles can enhance sustainable human network design. Engineered systems are often designed for maximum performance, but in many cases, robustness is lost due to unwanted variations in inputs or efficiency. Taguchi’s signal to noise ratio and other quality engineering principles are well known fundamentals in the field of robust design. In this paper, we will introduce flow-based metrics from ecological network analysis (ENA) for robustness, efficiency, and redundancy. Ecosystem robustness is related to the balance between flow path diversity and system delivery efficiency. Systems with diverse flows are more resilient to a disturbance since there are redundant pathways, but are inefficient because they contain many flow paths with the same endpoints. Efficient systems are better able to transfer material and energy, but this is at the cost of fewer pathways so the system is brittle. Thus to survive a disturbance, an ecosystem system balances redundancy with efficiency. Thermodynamic power cycles are used to understand the relationship between energy efficiency, measured using first law efficiency, and ecological robustness and an ecological balance of efficiency to redundancy (as measured by ascendency vs development capacity). The result highlights the importance of understanding differences in the meaning of efficiency between two fields, and that from an engineering standpoint robustness does not have to be sacrificed to obtain energy efficiency.

Abstract:
The goal of this case is for students to learn through the development of a sustainable river governance plan for Massachusetts focused on balancing needs and perspectives on local agriculture, flood resilience, and healthy ecosystems in the context of climate change. This will be challenging. Ideally, a river governance plan developed by the students would support local agriculture, increase flood resilience, and promote environmental stewardship. A role-playing exercise is included in this case that involves representatives of several stakeholders groups (personas assumed by a subset of students); these include a farmer, a fisher/recreationalist, a state river manager, an environmentalist, and a resident. The students will learn about the goals of a stakeholder to discuss with the others, negotiate with them, find ways to resolve conflicts and finally to create a governance plan.

Abstract:
Human activity has modified and deteriorated natural ecosystems in ways that reduce resilience and exacerbate environmental and climate problems. Physical measures to protect, manage and restore these ecosystems that also address societal challenges in sustainable ways and bring biodiversity benefits are sometimes referred to as “nature-based solutions” (NBS). For example, reducing deforestation and restoring forests is a major opportunity for climate mitigation, while protecting or restoring coastal habitats can mitigate damage to coastal areas from natural hazard events, in addition to potentially providing co-benefits related to livelihood, recreation, and biodiversity. There is now an impetus to shift towards greater deployment of nature-based solutions. Not only do they offer an alternative to conventional fossil fuel-based or hard infrastructure solutions but, if implemented correctly, they also hold great promise for achieving multiple goals, benefits and synergies. These include climate mitigation and resilience; nature and biodiversity protection; and economic and social gains. 2020 saw an explosion in publications about NBS, which have contributed to filling many of the knowledge gaps that existed around their effectiveness and factors for their success. These publications have also highlighted the knowledge gaps that remain and have revealed a lack of critical reflection on the social and economic sustainability aspects of NBS. Building on these gaps, we decided to launch this mini-series of four briefs to provoke a more nuanced discussion that highlights not only the potential benefits, but also the potential risks and trade-offs of NBS. The purpose is not to downplay the importance of NBS for biodiversity, ecosystems, and coastal mitigation and adaptation, but to ensure that we establish a dialogue about ways to overcome these challenges while leaving no one behind.
