[CBNPMP-Thèmes] BiodiversitéRésumé : The classification of plant species as native or exotic has ramifications for how they are treated within urban green space policy and practice. Green spaces are built or managed to fulfil a range of ecological and social functions, and decisions must be made about which plants to include to achieve these functions. There is growing literary and policy emphasis on native-only planting strategies, under the assumption that native species will deliver a greater range of biodiversity benefits. Yet, there remains a disconnection between theoretical debates on the definition or value of nativeness, and urban design practice. Using a systematic review, we examine the relationship between plant nativeness and animal biodiversity in urban areas. We argue that both the use and definition of native species involve value-laden decisions. The social roots of ‘native’ definitions have led to ambiguity in its use within the literature. Despite this ambiguity, we find that most studies show a positive influence of native plants on at least one measure of biodiversity, justifying their priority in urban plantings to support native animals. We conclude with considerations for the selection of plants for urban greening to promote native biodiversity: 1) the resources a plant provides are more important than its origin, but 2) when in doubt, ‘nativeness’ is a good surrogate of whether a plant will provide for local animals, and allows for the conservation of plants themselves; and 3) flexibility in scale of provenance allows for strategic responses to changing climates or competing objectives of urban design.

Titre : Thermal unmanned aerial vehicles for the identification of microclimatic refugia in topographically complex areas Type de document : Imprimé Auteurs : Raúl Hoffrén ; María Begoña García Année de publication : 2023 Article en page(s) : 113427 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Biodiversité Résumé : Biodiversity loss is one of the most relevant consequences of climate change. Therefore, identifying areas and environmental features that allow certain organisms to be less exposed to the effects of the current global warming is priority for biodiversity conservation. In this study, we describe a novel approach for the identification of microclimatic refugia in rugged mountain areas, specifically for the detection of most thermally stableareas, using an unmanned aerial vehicle (UAV) capable of recording in the visible and thermal infrared spectral bands. We estimated land surface temperatures (LST) at very-high spatial resolution in six topographically complex sectors of the Pyrenees (NE Spain), across seasons with vegetative activity (summer 2020, autumn 2020, spring 2021, and summer 2021), and at two thermally contrasted times of the day (early in the morning: LSTmin, and in the afternoon: LSTmax). LST were validated with a network of miniaturized temperature sensors in the field. LSTmin and LSTmax allowed us to calculate the daily thermal range of each sector across the seasons, and thus the most thermally stable areas over the year. To reveal the importance of different variables on low and narrow thermal ranges we applied Gradient Boosted Models to seven terrain variables derived from ALS-LiDAR (slope, northness, eastness, heat load, wind exposure index, SAGA’s topographic wetness index, and vector ruggedness measure) and a proxy of forest density through the three-dimensional point clouds of the UAV data. The northness was the variable that most promoted thermal stability, followed by the slope and forest density, so that microclimatic refugia resulted to be located in northern slopes, small sites under rocky cliffs, and forested areas. Our results demonstrate that thermal UAVs can become promising tools for the identification of microclimatic refugia in topographically complex areas, providing information at unprecedented spatial resolution, and thus of high interest for biodiversity conservation.

[CBNPMP-Thèmes] Enjeux de conservation des lacs d'altitude
[CBNPMP-Thèmes] Lac d'altitudeRésumé : Microorganisms are fundamental components to maintain the ecological integrity of any ecosystem. Microscopic organisms have been, however, mostly excluded in conservation studies and microbiology has been developed as a scientific discipline lacking a natural history background. The detailed genetic studies carried out in the Aigüestortes i Estany de Sant Maurici National Park and recent works in the mostly scarce literature, show that the mostly oligotrophic and highly diluted waters in high mountain lakes hold a larger microbial phylogenetic uniqueness than expected and are reservoirs of large evolutionary potential, providing an overall natural history perspective for alpine archaea, bacteria, fungi and protists. Microbes arise as an important part of the biological richness of these environments that should be considered as a fundamental component of the natural heritage. Microbial ecologists are now closer than ever to deal with conservation biology concepts such as biological richness, extinction, biotic interactions, and ecosystems management. First insights emerge for establishing the microbial tolerance to different environmental conditions, for estimating which is the potentiality of survival and dispersal abilities in the different species, and for highlighting how the underappreciated microbiota will respond to stresses and disturbances brought by the global change. Warming and eutrophication may jeopardise the most idiosyncratic microbial populations that have found in these (ultra)oligotrophic and diluted systems the most appropriate conditions to thrive. Environmental managers and lawyers, citizen, and stakeholders, in general, have now access to scientifically informed advice for the unseen microbial life in the unexpectedly rich high mountain microbial ecosystems.

[CBNPMP-Thèmes] Conservation des écosystèmes
[CBNPMP-Thèmes] HabitatsRésumé : Sustainable management of forest ecosystems requires the use of reliable and easy to implement biodiversity and naturalness indicators. Tree-relatedmicrohabitats (TreMs) can fulfill these roles as they harbor specialized species that directly or indirectly depend on them, and are generally more abundant and diverse in natural forests or forests unmanaged for several decades. The TreM concept is however still recent, implying the existence of many knowledge gaps that can challenge its robustness and applicability. To evaluate the current state of knowledge on TreMs, we conducted a systematic review followed by a bibliometric analysis of the literature identified. A total of 101 articles constituted the final corpus. Most of the articles (60.3%) were published in 2017 or after. TreM research presented a marked lack of geographical representativity, as the vast majority (68.3%) of the articles studied French, German or Italian forests. The main themes addressed by the literature were the value of TreMs as biodiversity indicators, the impact of forest management on TreMs and the factors at the tree- and stand-scales favoring TreMs occurrence. Old-growth and unmanaged forests played a key role as a “natural” forest reference for these previous themes, as TreMs were often much more abundant and diverse compared to managed forests. Arthropods were the main phylum studied for the theme of TreMs as biodiversity indicators. Other more diverse themes were identified, such as restoration, remote sensing, climate change and economy and there was a lack of research related to the social sciences. Overall, current research on TreMs has focused on assessing its robustness as an indicator of biodiversity and naturalness at the stand scale. The important geographical gap identified underscores the importance of expanding the use of the TreMs in other forest ecosystems of the world. The notable efforts made in recent years to standardize TreM studies are an important step in this direction. The novelty of the TreM concept can partially explain the thematic knowledge gaps. Our results nevertheless stress the high potential of TreMs for multidisciplinary research, and we discuss the benefits of expanding the use of TreMs on a larger spatial scale.

[LOTERRE-Biodiversité] Relation animal-végétalRésumé : Large wild ungulates are a major biotic factor shaping plant communities. They influence species abundance and occurrence directly by herbivory and plant dispersal, or indirectly by modifying plant-plant interactions and through soil disturbance. In forest ecosystems, researchers’ attention has been mainly focused on deer overabundance. Far less is known about the effects on understory plant dynamics and diversity of wild ungulates where their abundance is maintained at lower levels to mitigate impacts on tree regeneration. We used vegetation data collected over 10 years on 82 pairs of exclosure (excluding ungulates) and control plots located in a nation-wide forest monitoring network (Renecofor). We report the effects of ungulate exclusion on (i) plant species richness and ecological characteristics, (ii) and cover percentage of herbaceous and shrub layers. We also analyzed the response of these variables along gradients of ungulate abundance, based on hunting statistics, for wild boar (Sus scrofa), red deer (Cervus elaphus) and roe deer (Capreolus capreolus). Outside the exclosures, forest ungulates maintained higher species richness in the herbaceous layer (+15%), while the shrub layer was 17% less rich, and the plant communities became more light-demanding. Inside the exclosures, shrub cover increased, often to the benefit of bramble (Rubus fruticosus agg.). Ungulates tend to favour ruderal, hemerobic, epizoochorous and non-forest species. Among plots, the magnitude of vegetation changes was proportional to deer abundance. We conclude that ungulates, through the control of the shrub layer, indirectly increase herbaceous plant species richness by increasing light reaching the ground. However, this increase is detrimental to the peculiarity of forest plant communities and contributes to a landscape-level biotic homogenization. Even at population density levels considered to be harmless for overall plant species richness, ungulates remain a conservation issue for plant community composition.
