Full textAbstract:
AbstractFollowing severe stock collapses in many natural populations, efforts are now being invested in farming marine species, and in rehabilitating populations through controlled releases. While the development of cod farming is still relatively new, it may be wise to consider some of the problems other fish farming industries have encountered. For example, farmed fish generally have a different genotype from that of local wild populations, and these artificially selected fish are typically bigger and more aggressive than wild fish. These differences can be problematic if farmed fish escape and begin breeding with local wild populations. An alternative approach to farming is to rehabilitate local wild populations through restocking. To date, however, this approach has had mixed success. Fish behaviour develops during early life stages through a combination of innate characteristics and experience. Apparently, the capacity for behavioural flexibility later in life is affected by the early experiences of juvenile fish. Here, we review the literature concerning the role of population origin and juvenile experience on fish behaviour. We highlight our recent studies on Atlantic cod, which demonstrate that variability in the nursery habitat generates behaviourally flexible fish. We discuss these issues in the context of gadoid mariculture and restocking. We conclude that behavioural studies are an important part of applied research for developing an industry of fish farming in gadoids, as well as for research concerning restocking and conservation of marine resources.

Cloyd, Raymond A. "How Effective Is Conservation Biological Control in Regulating Insect Pest Populations in Organic Crop Production Systems?" Insects 11, no. 11 (October 29, 2020): 744. http://dx.doi.org/10.3390/insects11110744.
Full textAbstract:
Organic crop production systems are designed to enhance or preserve the presence of natural enemies, including parasitoids and predators, by means of conservation biological control, which involves providing environments and habitats that sustain natural enemy assemblages. Conservation biological control can be accomplished by providing flowering plants (floral resources) that will attract and retain natural enemies. Natural enemies, in turn, will regulate existing insect pest populations to levels that minimize plant damage. However, evidence is not consistent, based on the scientific literature, that providing natural enemies with flowering plants will result in an abundance of natural enemies sufficient to regulate insect pest populations below economically damaging levels. The reason that conservation biological control has not been found to sufficiently regulate insect pest populations in organic crop production systems across the scientific literature is associated with complex interactions related to intraguild predation, the emission of plant volatiles, weed diversity, and climate and ecosystem resources across locations where studies have been conducted.

Full textAbstract:
Access to natural resources has changed over the years in Zimbabwe. At least three broad periods of biodiversity conservation, utilisation, and access can be identified in the country, namely, the precolonial, colonial, and postindependence periods. This paper reviews the relationships between human livelihoods and biodiversity conservation in the rural areas of Zimbabwe during these periods and is informed by an extensive review of the relevant literature. A combination of historical narrative, thematic, and content analysis was used in analysing the various documents into meaningful information addressing the objective of the study. Traditional societies in precolonial Zimbabwe had access to abundant natural resources. However, access to these resources was not uncontrolled, but was limited by traditional beliefs, taboos, and customs enforced through community leadership structures. The advent of colonialism in the late 19th century dispossessed indigenous African communities of natural resources through command-type conservation legislation. At independence in 1980, the new majority government sought to redress the natural resource ownership imbalances created during colonialism, culminating in some significant measure of devolution in natural resource management to local communities in the late 1980s, though such devolution has been criticised for being incomplete. An accelerated land reform exercise since the year 2000 has adversely affected biodiversity conservation activities in the country, including the conservation-related livelihood benefits derived from protected areas. The review paper highlights the need for a more complete devolution of natural resource ownership and management down to the grassroots levels in the communal areas, if social and ecological sustainability is to be fully realised in these areas. On the other hand, the disruption of conservation activities in the country due to the ill-planned accelerated land reform exercise that has demarcated land for arable farming in some of the protected areas should be held in check as a matter of urgency.

Full textAbstract:
Medicinal plants are valued natural resources to maintain affordable and culture-specific health care. The reliance on these resources for optimal health care aligns with the World Health Organization's (WHO) recommendation to use traditional herbal medicine to meet primary health care needs. Nevertheless, this could potentially have adverse effects on the status and availability of the herbs in their natural habitats. This review outlines the utilisation of indigenous knowledge and methods to preserve indigenous medicinal plants for future accessibility and utilisation. The data presented in the review is obtained from national and international literature on indigenous use and management of natural resources. The review's findings indicate that the sustainable use of medicinal plants is influenced by taboos, seasonal and societal limitations on harvesting, and adherence to regulations on the collection of medicinal plants. Implementing indigenous conservation techniques could effectively help counteract the extinction of medicinal plant species caused by the adverse effects of climatic extremes on biodiversity.

AbstractThe submarine habitats in the Rio Lagartos Sea Turtle Sanctuary, Mexico, are an important feeding and development area for juvenile Hawksbill turtles (Eretmochelys imbricata). The characterization of these critical habitats is an important and urgent issue to attend for the conservation of this species in Mexico. The objective of this study is to identify, locate and describe the marine benthic habitats in this area, and explain the distribution of the juvenile Hawksbill turtles in the study area. We used submarine techniques such as videotransects and spot checks to characterize the bottom types in the area, and geostatistic techniques to elaborate thematic maps of the different benthic components, integrating all of them into a GIS. We obtained the bottom type map with eight submarine habitats at different depth ranges. We found juvenile Hawksbill turtles distributed mainly on hard bottom sites covered by octocorals, such as Pseudopterogorgia, and sponges of the genera Chondrilla and Spheciospongia. We estimated habitat ranges for the captured turtles and the bottom types occupied by them, then we calculated the distribution densities of juvenile Hawksbill turtles by bottom type. We concluded that the combination of spatial techniques and multivariate statistics is efficient for mapping the marine bottom types in the area, and recommend the generation of specific conservation strategies to protect this area because of the natural marine resources and process ocurring in it.

Introduction: Biodiversity conservation is a global concern. With the advancement of agricultural frontiers, the excessive use of natural resources, pollution, urban and industrial expansion, innovative approaches that seek to face these emerging challenges become necessary; In this context, seeking practices that align scientific and traditional knowledge in biodiversity conservation, the model known as ethnoconservation emerges, which aims to strengthen the relationship between society and the environment. Objective: To address concepts of ethnoconservation, explaining the challenges for its implementation. Methodology: This is a descriptive literature review, with research carried out at Scielo and 8 articles used. Literature review: The literature addresses collective methods of appropriation of natural resources in relation to the norms of reciprocal behavior linked to them. It is pointed out that these models of cooperation and mutual assistance result in the formation of an intergroup system of economic balance. Environmental conservation, in partnership with community care, generates economic returns for the community, whether in the commercialization of products in a non-predatory way, or even in their exposure through ethnotourism. Final considerations: despite the benefits proposed by ethnoconservation, there are challenges faced in its implementation, especially in Brazil, where conservation practice is often undemocratic and distant from the knowledge of traditional populations.

AbstractIntegrated Natural Resource Conservation and Development (INRCD) Projects promote community economic development consistent with natural resource conservation. Such projects are studied analytically as system design optimization problems comprising engineering, economic, and social considerations. Modeling social benefits as objectives or constraints requires proper quantification. From the extant literature, we decompose the social benefits concept into quantifiable INRCD attributes and point to further quantification efforts needed to capture the system design's impact on local communities.

Devine, Matthew T. "Juvenile River Herring in Freshwater Lakes: Sampling Approaches for Evaluating Growth and Survival." 2017. https://scholarworks.umass.edu/masters_theses_2/574.
Full textAbstract:
River herring, collectively alewives (Alosa pseudoharengus) and blueback herring (A. aestivalis), have experienced substantial population declines over the past five decades due in large part to overfishing, combined with other sources of mortality, and disrupted access to critical freshwater spawning habitats. Anadromous river herring populations are currently assessed by counting adults in rivers during upstream spawning migrations, but no field-based assessment methods exist for estimating juvenile densities in freshwater nursery habitats. Counts of 4-year-old migrating adults are variable and prevent understanding about how mortality acts on different life stages prior to returning to spawn (e.g., juveniles and immature adults in lakes, rivers, estuaries, and oceans). This in turn makes it challenging to infer a link between adult counts and juvenile recruitment and to develop effective management policy. I used a pelagic purse seine to investigate juvenile river herring densities, growth, and mortality across 16 New England lakes. First, I evaluated the effectiveness and sampling precision of a pelagic purse seine for capturing juvenile river herring in lakes, since this sampling gear has not been systematically tested. Sampling at night in June or July resulted in highest catches. Precision, as measured by the coefficient of variation, was lowest in July (0.23) compared to June (0.32), August (0.38), and September (0.61). Simulation results indicated that the effort required to produce precise density estimates is largely dependent on lake size with small lakes (<50 >ha) requiring up to 10 purse seine hauls and large lakes (>50 ha) requiring 15–20 hauls. These results suggested that juvenile recruitment densities can be effectively measured using a purse seine at night in June or July with 10–20 hauls. Using juvenile fishes captured during purse seining in June–September 2015, I calculated growth and mortality rates from sagittal otoliths. Density, growth, and mortality were highly variable among lakes, and mixed-effects regression models explained 11%–76% of the variance in these estimates. Juvenile densities ranged over an order of magnitude and were inversely related to dissolved organic carbon. Juvenile growth rates were higher in productive systems (i.e., low secchi depth, high nutrients) and were strongly density-dependent, leading to much larger fish at age in productive lakes with low densities of river herring compared to high density lakes. Water temperature explained 56%–85% of the variation in juvenile growth rates during the first 30 days of life. Mortality was positively related to total phosphorous levels and inversely related to hatch date, with earlier hatching cohorts experiencing higher mortality. These results indicate the importance of water quality and juvenile densities in nursery habitats for determining juvenile growth and survival. This study encourages future assessments of juvenile river herring in freshwater and contributes to an understanding of factors explaining juvenile recruitment that can guide more effective and comprehensive management of river herring.

Full textAbstract:
The purpose of this annotated bibliography is to guide middle school and
high school students into critical thinking about environmental issues. Through
keen observation of their bioregion and through an integration of interdisciplinary
literature which focuses on Oregon writers, students will be challenged to think,
write, and discuss current issues effecting local natural resources. The bibliography
was designed to incorporate integrated learning, collaborative activities, and handson
investigation.
The students' community becomes a learning laboratory, a place in which to
identify, a place to value, and a place to contribute through active participation in
restoration of resources and through other positive activities. Learning to respect
diverse and complex viewpoints on environmental issues will help develop good
evaluative skills. As responsible, participating members of their community,
students can be encouraged to lead the way, providing good role models both to
families and to younger students.
The diverse literary collection will provide access to a broad range of voices
about the land and Oregon, in particular. These become invitations for students to
write about their place, their home. Writing empowers students to make
connections between experience, thought, and word. Students writing, thinking,
and reseeing their community as a place to value and protect is the goal of Time to
Listen.Graduation date: 1995

AbstractAgricultural production systems, for example, conservation agriculture, climate smart agriculture, organic agriculture, sustainable landuse management, and others, summarized under the term “sustainable intensification,” have been introduced in African countries to increase productivity and to adapt/mitigate CC (CCAM). But the productivity of smallholder farming systems in Africa remains low. High erosion, contaminated water, threatened human health, reduced soil water, and natural resources functionality, that is, ecosystems services, and decreased biodiversity dominate. Low support in the farm environment is also responsible for this situation.It is hypothesized, based on the huge body of literature on CCAM, that the implementation of already existing arable and plant cultivation methods like crop diversity, alley crops, forage legume-based crop rotations, mulching, organic matter recycling, and reduced tillage intensity will increase CCAM performance and also farm productivity and income. Based on a brief analysis of CCAM relevant arable and plant cultivation methods and agricultural production systems potentials and challenges, this chapter offers guidance for further transforming climate robust African farming systems.

AbstractSolar energy is one of the most promising sources for low carbon energy production. In particular, PV panels and thermal solar collectors can be easily integrated into new and existing buildings to improve their energy efficiency and sustainability. On the other hand, solar-based technologies require extraction of natural resources and processing, thus materials conservation and recovery are vital to effectively contribute to the decarbonization of the construction sector. The paper is meant to be a brief state of the art that summarizes the relevant issues for achieving the goal of circular economy of buildings with the focus on solar energy application, with the novelty of considering and comparing two technologies, photovoltaic and thermal. Most of the scientific literature was dedicated to PV technologies due to the increasing importance of the electrification process and the usage of materials with reduced availability. Thermal solar collectors were mainly analysed developing LCA without a larger point of view embracing circularity concepts. Apart from the technological matters, the investigation highlights social, behavioral, and economic aspects that can be crucial to trace the route to circular economy.

Full textAbstract:
Sustainable management of natural forest resources is a vital requirement in the changing climatic conditions on Earth. Two advances techniques, hyperspectral remote sensing (HRS) and LIDAR (light detection and ranging) remote sensing (LRS), provide more enhanced and accurate measurements than that of conventional optical remote sensing (ORS). Hyperspectral sensor like AVIRIS, which has hundreds of narrow bands, have advantages over a broadband multispectral sensor. In addition, the fusion of HRS and LRS can play an essential role in assessing biophysical and biochemical variables of forest species. In this chapter, the authors reviewed the extant literature and tried to understand the position of HRS, LRS, and their integration with the machine and deep learning algorithms for the effective monitoring and management of natural forest resources. Further, scopes and challenges are also discussed to enhance the effectiveness of these techniques in natural forest resources management.

Full textAbstract:
This chapter delves into the intricate relationship between agro-pastoralism and grassland ecosystems in Tanzania’s Western Serengeti and Ugalla Ecosystems. Despite the acknowledged contribution of agro-pastoralism to rural well-being and economic development, its impact on the delicate balance of grassland ecosystems remains unclear in these crucial Tanzanian landscapes. The chapter aims to illuminate agro-pastoralism’s environmental, social, and economic dimensions in these regions. Guided by research questions exploring current conditions, potential solutions, and the path toward sustainable grassland resource utilization, the study employed a systematic literature review and data analysis using R software. Key findings highlight challenges from the progressive expansion of agro-pastoral activities, leading to trade-offs between ecosystem services and productivity. The study identifies agro-pastoral clusters across the area, revealing variations in economic activities and their impact on grassland utilization. Impacts on natural resources, such as soil pH changes, reduced herbaceous biomass, and shifts in plant composition, are discussed. The legal framework related to natural resource conservation in grasslands emphasizes the need for a balanced, ecologically sustainable approach. Efforts to alleviate agro-pastoral impacts, including introducing climate-smart agriculture, are explored. The chapter concludes by emphasizing the importance of integrated, participatory methods for sustainable management in the Serengeti and Ugalla ecosystems. Recommendations include promoting sustainable land use practices, implementing rotational grazing, and enhancing community involvement in decision-making.

Full textAbstract:
This chapter encompasses a literature survey and strategic analysis to understand the elaboration and implementation of Participatory Forest Management (PFM) in Benin, with a focus on the case of the “Forêt des Trois Rivières”. By analyzing the historical background of forest management systems in Benin, we highlighted two major turning points. The first relates to the creation and autocratic management of protected forests, which took place from 1940 to 1990. The second change took place after the Rio conference in 1992, and this emphasized the importance of local communities in natural resources management. Moreover, the results of our strategic analysis of stakeholders involved in the specific case of Participatory Forest Management Plan (PFMP) of the “Forêt des Trois Rivières” showed that it is important to emphasize on active community participation while designing a participatory management plan and for decision making at the implementation stage. We also observed that alliances between foresters and timber loggers are likely to hinder the achievement of the PFM objectives.

Full textAbstract:
The marine aquaculture and fisheries industries play an important role in global food security and nutrition. However, the natural (aquatic) resources are subjected to over-exploitation. The marine ecosystem also faces significant biodiversity threats that impact the long-term viability and sustainability of the industry. Given their ecological importance, it is necessary to understand the specific biodiversity challenges and the related solutions that can be used to promote the sustainable development of the sectors. This chapter provides an overview of the academic literature dealing with the biodiversity implications of the aquaculture and fisheries industries. How some of the industry’s leaders report on their efforts to manage biodiversity-related challenges is considered. Findings reveal that organisations play an important role in the conservation of biodiversity by assessing their direct and indirect impacts on the ecosystems, implementing solutions to manage these concerns, integrating biodiversity management into the business model and evaluating sustainability performance.

<em>Abstract.</em> —Freshwater tropical island environments support a variety of fishes that provide cultural, economic, and ecological services for humans but receive limited scientific, conservation, and public attention. Puerto Rico is a Caribbean tropical island that may serve as a model to illustrate the interactions between humans and natural resources in such complex ecosystems. The native freshwater fish assemblage of Puerto Rico is distinct from mainland assemblages in that the assemblage is not diverse, all species are diadromous, and they may be exploited at multiple life stages (e.g., postlarva, juvenile, adult). Primary large-scale drivers of recent water-use policy include economic growth, human population density, and urbanization, with climate change as an overarching influence. Watershed and riparian land use, water quality, river flow and instream physical habitat, river habitat connectivity, exotic species, and aquatic resource exploitation are important proximate factors affecting the ecosystem and fisheries. Research on ecological processes and components of the stream and river fish assemblages has expanded the knowledge base in the past decade with the goal of providing critical information for guiding the conservation and management of the lotic resource to optimize ecosystem function and services. The greatest challenge facing Caribbean island society is developing policies that balance the needs for human water use and associated activities with maintaining aquatic biodiversity, ecological integrity and services, and sustainable fisheries. Achieving this goal will require broad cooperation and sustained commitment among public officials, agency administrators, biologists, and the public toward effective resource management.

Tetzlaff, Sasha, Jinelle Sperry, and Brett DeGregorio. You can go your own way : no evidence for social behavior based on kinship or familiarity in captive juvenile box turtles. Engineer Research and Development Center (U.S.), August 2022. http://dx.doi.org/10.21079/11681/44923.
Full textAbstract:
Behavioral interactions between conspecific animals can be influenced by relatedness and familiarity. To test how kinship and familiarity influenced social behavior in juvenile Eastern Box Turtles (Terrapene carolina), 16 captive-born individuals were reared under semi-natural conditions in four equally sized groups, where each group comprised pairs of siblings and non-siblings. Using separation distance between pairs of turtles in rearing enclosures as a measure of gregariousness, we found no evidence suggesting siblings more frequently interacted with one another compared to non-relatives over the first five months of life. Average pair separation distance decreased during this time but may have been due to turtles aggregating around resources like heat and moist retreat areas as colder temperatures approached. At eight months old, we again measured repeated separation distances between unique pair combinations and similarly found no support for associations being influenced by kinship. Agonistic interactions between individuals were never observed. Based on our results, group housing and rearing of juvenile box turtles did not appear to negatively impact their welfare. Unlike findings for other taxa, our results suggest strategically housing groups of juvenile T. carolina to maintain social stability may not be an important husbandry consideration when planning releases of captive-reared individuals for conservation purposes.

Status of perennial tree germplasm resources in India and their utilization in the context of global genome sequencing efforts. World Agroforestry, 2020. http://dx.doi.org/10.5716/wp20050.pdf.
Full textAbstract:
Tree species are characterized by their perennial growth habit, woody morphology, long juvenile period phase, mostly outcrossing behaviour, highly heterozygosity genetic makeup, and relatively high genetic diversity. The economically important trees have been an integral part of the human life system due to their provision of timber, fruit, fodder, and medicinal and/or health benefits. Despite its widespread application in agriculture, industrial and medicinal values, the molecular aspects of key economic traits of many tree species remain largely unexplored. Over the past two decades, research on forest tree genomics has generally lagged behind that of other agronomic crops. Genomic research on trees is motivated by the need to support genetic improvement programmes mostly for food trees and timber, and develop diagnostic tools to assist in recommendation for optimum conservation, restoration and management of natural populations. Research on long-lived woody perennials is extending our molecular knowledge and understanding of complex life histories and adaptations to the environment, enriching a field that has traditionally drawn its biological inference from a few short-lived herbaceous species. These concerns have fostered research aimed at deciphering the genomic basis of complex traits that are related to the adaptive value of trees. This review summarizes the highlights of tree genomics and offers some priorities for accelerating progress in the next decade.

Hudgens, Bian, Jene Michaud, Megan Ross, Pamela Scheffler, Anne Brasher, Megan Donahue, Alan Friedlander, et al. Natural resource condition assessment: Puʻuhonua o Hōnaunau National Historical Park. National Park Service, September 2022. http://dx.doi.org/10.36967/2293943.
Full textAbstract:
Natural Resource Condition Assessments (NRCAs) evaluate current conditions of natural resources and resource indicators in national park units (parks). NRCAs are meant to complement—not replace—traditional issue- and threat-based resource assessments. NRCAs employ a multi-disciplinary, hierarchical framework within which reference conditions for natural resource indicators are developed for comparison against current conditions. NRCAs do not set management targets for study indicators, and reference conditions are not necessarily ideal or target conditions. The goal of a NRCA is to deliver science-based information that will assist park managers in their efforts to describe and quantify a park’s desired resource conditions and management targets, and inform management practices related to natural resource stewardship. The resources and indicators emphasized in a given NRCA depend on the park’s resource setting, status of resource stewardship planning and science in identifying high-priority indicators, and availability of data and expertise to assess current conditions for a variety of potential study resources and indicators. Puʻuhonua o Hōnaunau National Historical Park (hereafter Puʻuhonua o Hōnaunau NHP) encompasses 1.7 km2 (0.7 mi2) at the base of the Mauna Loa Volcano on the Kona coast of the island of Hawaiʻi. The Kona coast of Hawaiʻi Island is characterized by calm winds that increase in the late morning to evening hours, especially in the summer when there is also a high frequency of late afternoon or early evening showers. The climate is mild, with mean high temperature of 26.2° C (79.2° F) and a mean low temperature of 16.6° C (61.9° F) and receiving on average 66 cm (26 in) of rainfall per year. The Kona coast is the only region in Hawaiʻi where more precipitation falls in the summer than in the winter. There is limited surface water runoff or stream development at Puʻuhonua o Hōnaunau NHP due to the relatively recent lava flows (less than 1,500 years old) overlaying much of the park. Kiʻilae Stream is the only watercourse within the park. Kiʻilae Stream is ephemeral, with occasional flows and a poorly characterized channel within the park. A stream gauge was located uphill from the park, but no measurements have been taken since 1982. Floods in Kiʻilae Stream do occur, resulting in transport of fluvial sediment to the ocean, but there are no data documenting this phenomenon. There are a small number of naturally occurring anchialine pools occupying cracks and small depressions in the lava flows, including the Royal Fishponds; an anchialine pool modified for the purpose of holding fish. Although the park’s legal boundaries end at the high tide mark, the sense of place, story, and visitor experience would be completely different without the marine waters adjacent to the park. Six resource elements were chosen for evaluation: air and night sky, water-related processes, terrestrial vegetation, vertebrates, anchialine pools, and marine resources. Resource conditions were determined through reviewing existing literature, meta-analysis, and where appropriate, analysis of unpublished short- and long-term datasets. However, in a number of cases, data were unavailable or insufficient to either establish a quantitative reference condition or conduct a formal statistical comparison of the status of a resource within the park to a quantitative reference condition. In those cases, data gaps are noted, and comparisons were made based on qualitative descriptions. Overall, the condition of natural resources within Puʻuhonua o Hōnaunau NHP reflects the surrounding landscape. The coastal lands immediately surrounding Puʻuhonua o Hōnaunau NHP are zoned for conservation, while adjacent lands away from the coast are agricultural. The condition of most natural resources at Puʻuhonua o Hōnaunau NHP reflect the overall condition of ecological communities on the west Hawai‘i coast. Although little of the park’s vegetation...

Full textAbstract:
The Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 mandat¬ed the research and management of the nation’s deep-sea coral resources through establishment of the National Oceanic and Atmospheric Administra¬tion’s Deep Sea Coral Research and Technology Program. The challenge for Alaska was daunting, where expansive, world-class fisheries often coincided with extraordinarily rich coral habitats for a high-latitude region. The first chal¬lenge was to inventory known locations of deep-sea corals. Many coral records and some museum collections existed from Alaska, but the taxonomy of cor¬als was little studied and field iden¬tification of corals was problematic. Formal bycatch programs and research activities in recent decades provided many more specimens for taxonomic study, but guides to species were largely incomplete, inaccurate, and outdated given the fast pace of species discovery in Alaska. We provide a comprehen¬sive, up-to-date guide, detailing 161 coral taxa identified from museum collections, primary literature, and video records. Each profile includes a description, images for each taxon, taxonomic history, biology, ecology, geographical distribution, and habitat, including depth distribution. Corals are found in the six regions of Alaska but the coral fauna of the Aleutian Islands is by far the most species rich. The state of taxonomy for some coral groups is ex¬cellent, while others require additional collections and more taxonomic work. Construction of this guide resulted in descriptions of several antipatharian species, published separately from this guide (Alternatipathes mirabilis, Bathypathes alaskensis, B. ptiloides, B. tiburonae, and Parantipathes pluma) and the scleractinian Flabellum (Flabel¬lum) oclairi Cairns, sp. nov. described herein. The guide provides informa¬tion for targeting new collections and identifying areas of high abundance and indicator species of vulnerable marine ecosystems. Stakeholders can now more adequately assess Alaska’s coral resources and risks from natural and anthropogenic stressors.

Building Bridges: Innovations and Approaches to Increase Financing to Indigenous and Afro-descendant Peoples and Local Communities for Climate and Conservation Goals. Rights and Resources Initiative, December 2022. http://dx.doi.org/10.53892/ypxi4263.
Full textAbstract:
Indigenous Peoples, local communities, and Afro-descendant Peoples must be recognized and supported as key actors and leaders in combatting climate change and conserving the Earth’s natural diversity to have any hope of reaching global climate and biodiversity goals. The men and women in these groups have long stewarded their lands, territories, and resources, across an estimated 50% of the global land area. Scientific studies and local experience have increasingly demonstrated that Indigenous Peoples, Afro-descendant Peoples, and local communities with secure tenure and support are often highly effective stewards of forests and other natural ecosystems, with high levels of ecological intactness and low levels of deforestation in their lands relative to other areas. This paper provides an initial overview of emerging experience with “fit for purpose” approaches to channel resources at scale to collective rightsholders and their supporting organizations to conserve and manage forests and rural landscapes. It draws on presentations and discussions from Path to Scale dialogues, a review of recent, relevant literature, public events and further inputs from Path to Scale participants and RRI coalition members.
