Full textThe aesthetic value of landscapes and species is a central element for the conservation of biodiversity, since it involves the emotional and emotional dimensions of our relationship to nature. However, the links between biodiversity and aesthetic perception remains poorly studied and recognized within the ecosystem services framework.Following a first critical review, that described the conceptual and methodological bases of landscape aesthetics, three studies on underwater systems at different scales have been computed in order to better understand the link between the different facets of biodiversity and aesthetic perception.The results revealed that the link between biodiversity and aesthetic preferences is dependent on the scale of perception: at a multi-specific scale, biodiversity and species composition have a positive effect on aesthetic preferences, while preferences at a specific scale are disconnected to the ecological functioning of ecosystems.These results confirm the importance of aesthetic value in our perception of biodiversity, which could have major consequences in the way we protect our environment. The aesthetic experience based on the understanding of ecological functioning is proposed and described in order to promote an aesthetic perception relevant to ecological processes. Education to biodiversity based on engaged aesthetic is also proposed, in order to reconnect ecological needs and aesthetic preferences
Roulier, Marine. "Cycle biogéochimique de l'iode en écosystèmes forestiers." Thesis, Pau, 2018. http://www.theses.fr/2018PAUU3026/document.
Full textAs radioisotopes of iodine may concentrate in thyroid gland, 131I (t1/2 = 8.07 days) and 129I (t1/2 = 15.7 106 years) are of health concern. 129I is of major radioecological importance because it can potentially integrate natural biogeochemical cycle of its stable isotope (127I) due to its long half-life. Forests, characterized by their longevity, a high biomass turnover and a strong influence on hydrological and nutrients cycles, can intercept, recycle and accumulate a significant amount of pollutants and radionuclides released into environment. In this context, research developed in this thesis had the purpose of correct long-term prediction of iodine behaviour in forest ecosystems.Rainfall appears to be a significant input flux of iodine in forest soils and vegetation, depending on coastal distance and precipitation amount. Forest canopy modifies quantities and speciation of iodine initially present in rainfall. Humus would act as temporary iodine accumulation layer through its association with organic matter. However, humus layer also behaves as potential iodine mobilisation source by leaching and/or volatilization. This thesis has demonstrated that iodine levels in soils depend both on its atmospheric and litterfall inputs, but also on the soil's ability to fix iodine. Thus, environmental conditions characterized by organic matter accumulation and presence of metal (hydr)oxides in soils promote iodine retention. Thereafter, soil is the main iodine reservoir at the forest plot scale (~99.9%). Given small amounts of iodine in the trees (<0.03% of the total iodine stock), recycling of iodine by vegetation is low, iodine being not an essential element for vegetables.This thesis contributes to fill some gaps in the knowledge of iodine distribution within forests and on the processes of iodine reemission related to organic matter degradation. Data generated by this thesis help to better understand the modeling of iodine cycle in this forest ecosystem

Full textEcological systems are not simple but composed of many different elements(species, for example) interacting with each other. These networks ofinteractions exhibit structural properties that determine ecological systems’ability to absorb and recover from perturbations. Mappinginteractions along with their changes in time and space is therefore key tounderstand and predict empirical communities' response to global changes.In this thesis, we used plant communities as model systems (i) to explore howspatial patterns may help identify feedbacks loops which make communities morefragile to upcoming changes and (ii) to map species interactions in empiricalcommunities and describe how they change along stress gradients and recover fromperturbations. To do so, we used two datasets documenting plant communities insubalpine meadows (USA) and Mediterranean grasslands (France).Our results show that feedback loops can be inferred to some extent from thespatial patterns of plant communities and hence help identify communities thatmay respond more abruptly to perturbations. Going to a more detailed level ofdescription, plant-plant interactions (as measured through spatial associations)were shown to respond strongly and consistently to stress but exhibited a weakresilience to disturbances.This work shows that plant-plant interactions -- which are linked to the response of the community to perturbations -- can be uncovered using spatial patterns. It paves the way towards a better understanding and a better anticipation capacity of how ecological communities might reorganize when subject to disturbances

Full textLand degradation directly affects over a billion hectares throughout the world. It is a threat to almost 35% of the planet’s land as well as to the means of subsistence of two billion people. Estimations of heavy financial losses are increasing year after year. The degradation of arid and semi-arid lands is a serious drawback to the development of the countries concerned. This problem is today unsolved and since a number of organizations within the international community have not found an appropriate, perennial solution, we are powerlessly witnessing the progression of this plague despite the efforts and experiments carried out all over the world. It has become extremely urgent to find solutions that are not only technical, but also social, economic and cultural.This assessment calls for action and the need to exploit different approaches based on the most recent advanced technology. Mobile robotics are a lead to explore and may well contribute to slowing down this phenomenon in the near future. This technology offers endless possibilities in many fields: healthcare, personal assistance, military, agriculture and of course the restoring of ecosystems. It will therefore be necessary to follow the evolution of this sector and observe its effects on the environment and society in general in those regions affected by the phenomenon. Our findings aim to propose a technical solution, and the more general questions regarding societal consequences are not examined; our main concern is to demonstrate and evaluate the resilience capacity of a solution based on robotic techniques. This document is part of the R-Stepps project to experiment a fleet of robots to combat land degradation and reverse the progress of desertification. Its main mission is reforestation, maintenance and surveillance of such zones. The fleet of robots is composed of various platforms, each with a specific function. By limiting each robot to one task, this will ensure their solidity and simple design

Full textIn this study, we got interested in quantifying how local and landscape metrics structure arthropod communities in agro-ecosystems. For that, we used a long-term monitoring design located in ‘Ille-Et-Vilaine’ (Brittany, France), composed by spatially pair-matched fields under organic vs. conventional farming systems. First, we found that landscape heterogeneity, also interacting with farming systems, drives the diversity and abundance of trophic groups for both ground- and vegetation-dwelling arthropods. In a second chapter, we showed the importance of landscape context in shaping assemblages of predatory arthropods, and suggested that mechanisms behind the distribution of individual species strongly differ between spiders and carabids. Lastly, we highlighted the importance of distinguishing between resident (emergent) and mobile (circulating) individuals when assessing the differential role of local vs. landscape factors in community assembly. Overall, our results show a strong and positive effect of organic farming on arthropod populations, assemblages and communities, both at local and landscape scales, as well as in interaction with other landscape metrics. We also highlighted the relevance of using different levels of biological organization, and related response variables, when assessing the structure and functioning of arthropod communities in agroecosystems
