Climate warming is driving changes in species distribution, but habitat characteristics can interact with warming temperatures to affect populations in unexpected ways. We investigated wintering waterbird responses to climate warming depending on habitat characteristics, with a focus on the northern boundary of their non‐breeding distributions wher...

We present the development dynamics of a national program for the population monitoring of the stone curlew (Burhinus oedicnemus) in France. This initiative aims to enhance scientific knowledge for the conservation of this heritage species within agroecosystems and to refine compensation measures. www.oedicneme-criard.ovh www.oedicneme.com contact...

Sea‐level rise (SLR) is expected to cause major changes to coastal wetlands, which are among the world's most vulnerable ecosystems and are critical for nonbreeding waterbirds. Because strategies for adaptation to SLR, such as nature‐based solutions and designation of protected areas, can locally reduce the negative effects of coastal flooding unde...

Breeding birds in agricultural landscapes have declined considerably since the 1950s and the beginning of agricultural intensification in Europe. Given the increasing pressure on agricultural land, it is necessary to identify conservation measures that consume little productive land. We tested the compensation hypothesis which states that field mar...

Climate warming is driving species to shift their geographical distribution poleward to track suitable climatic conditions. Two strategies have been suggested to help species respond to climate warming: facilitating distribution change or improving persistence. We questioned whether habitat management in favour of duck hunting activities interacted...

Thermal adjustment of waterbird communities to climate warming is crucial but hampered by natural habitat conversion, increasing their climatic debt. As it is, in contrast, facilitated in protected areas, assessing the adequacy of the current protected areas network with respect to future climate and land-use changes and identifying priority sites...

The establishment of high-throughput sequencing technologies and subsequent large-scale genomic datasets has flourished across fields of fundamental biological sciences. The introduction of genomic resources in fisheries management has been proposed from multiple angles, ranging from an accurate re-definition of geographical limitations of stocks a...

The relationships between species abundance or occurrence versus spatial variation in climate are commonly used in species distribution models (SDMs) to forecast future distributions. Under “space‐for‐time‐substitution”, the effects of climate variation on species are assumed to be equivalent in both space and time. Two unresolved issues of space‐f...

Protected areas are the cornerstone of biodiversity conservation to protect species and habitats. By 2030, we will have to protect 30% of the terrestrial surface to achieve the new target of the Post-2020 Biodiversity Framework (Convention on Biological Diversity). The Mediterranean Basin is a biodiversity hotspot shared between countries with diff...

Based on the Baltic Earth Assessment Reports of this thematic issue in Earth System Dynamics and recent peer-reviewed literature, current knowledge of the effects of global warming on past and future changes in climate of the Baltic Sea region is summarised and assessed. The study is an update of the Second Assessment of Climate Change (BACC II) pu...

Protected area networks help species respond to climate warming. However, the contribution of a site's environmental and conservation‐relevant characteristics to these responses is not well understood. We investigated how composition of nonbreeding waterbird communities (97 species) in the European Union Natura 2000 (N2K) network (3018 sites) chang...

Wetland bird species have been declining in population size worldwide as climate warming and land-use change affect their suitable habitats. We used species distribution models (SDMs) to predict changes in range dynamics for 64 non-passerine wetland birds breeding in Europe, including range size, position of centroid, and margins. We fitted the SDM...

This Climate Change Fact Sheet provides the latest scientific knowledge on how climate change is currently affecting the Baltic Sea and how it is expected to develop in the foreseeable future. It is aimed at guiding policymakers to take climate change into account, but also to the general public. Updated Baltic Sea Climate Change Fact Sheets are ex...

The Mediterranean Basin is a biodiversity hotspot. Wetlands make a key contribution to this status, but many of them remain outside the Ramsar network fifty years after the establishment of the Ramsar Convention. Here we evaluate the extent to which the Mediterranean Ramsar network covers wetlands of international importance for wintering waterbird...

Based on the Baltic Earth Assessment Reports of this thematic issue in Earth System Dynamics and recent peer-reviewed literature, current knowledge about the effects of global warming on past and future changes in climate of the Baltic Sea region is summarized and assessed.

Climate warming is driving changes in species distributions, although many species show a so-called climatic debt, where their range shifts lag behind the fast shift in temperature isoclines. Protected areas (PAs) may impact the rate of distribution changes both positively and negatively. At the cold edges of species distributions, PAs can facilita...

In biodiversity monitoring, large datasets are becoming more and more widely available and are increasingly used globally to estimate species trends and conservation status. These large‐scale datasets challenge existing statistical analysis methods, many of which are not adapted to their size, incompleteness and heterogeneity. The development of sc...

Climate warming is driving changes in species distributions and community composition. Many species have a so‐called climatic debt, that is, shifts in range lag behind shifts in temperature isoclines. Inside protected areas (PAs), community changes in response to climate warming can be facilitated by greater colonization rates by warm‐dwelling spec...

Manuel en français pour les outils et concepts de biologie de la conservation des oiseaux marins.

Aim. This study investigates whether, and how the composition of riparian bird communities has been affected by climate warming and habitat change. Although these two forces act separately, their respective contributions are rarely examined. Moreover, while the response of a given community may be a function of latitude and altitude, most studies h...

Fire plays a major role in many biomes, is widely used as a management tool and is likely to be affected by climate change. For effective conservation management, it is essential to understand how fire regimes affect different taxa, yet responses of invertebrates are particularly poorly documented. We tested how different fire frequencies influence...

Le changement climatique bouleverse les écosystèmes et notre aptitude à les conserver. La gestion et la protection des milieux naturels peuvent se montrer utiles pour faciliter l’adaptation des espèces aux changements globaux.

En réponse au réchauffement climatique, les oiseaux décalent leur distribution vers les pôles, mais les pressions sur leurs habitats et leurs populations freinent leur adaptation. Deux études récentes ont évalué les changements de distribution d’une centaine d’espèces d’oiseaux d’eau hivernant en Méditerranée sur plus de vingt ans. Les mesures de p...

Wetlands are known to support diverse and unique species assemblages. Globally, but particularly in the Mediterranean basin, they are threatened by climate change and natural habitat loss. Despite an alarming decline of wetlands over the last century, standardised and systematic site assessments at large scale do not exist. Here, we perform an inte...

Although the impacts of climate and land‐use changes on biodiversity have been widely documented, their joint effects remain poorly understood. We evaluated how nonbreeding waterbird communities adjust to climate warming along a gradient of land‐use change. Using midwinter waterbird counts (132 species) at 164 major nonbreeding sites in 22 Mediterr...

Although biological conservation is based on international agreements, its effectiveness depends on how countries implement such recommendations as effective conservation tools. The Ramsar Convention is the oldest international treaty for wetland and waterbird conservation, establishing the world's largest network of protected areas. However, since...

Skuas are top predator and scavenger seabirds in marine and terrestrial ecosystems and monitoring their diet can provide valuable insights on the abundance and distribution of prey. The diet of the brown skua was studied at Mayes Island, Kerguelen archipelago, by collection of prey remains during their breeding cycle in 2013. We investigated a pote...

The Ramsar Convention is the multilateral agreement aimed at protecting wetlands globally. Wetlands are particularly recognized for their role in the Mediterranean biodiversity hotspot by providing key habitats for endemic and migratory species, directly contributing benefits to the lives of people and being an integral part of their culture. In re...

Les activités humaines menacent gravement la biodiversité. Sous le terme de changements globaux, la sur-exploitation des populations et la destruction/dégradation des habitats arrivent en tête de liste des facteurs responsables de l’érosion de la biodiversité. Le changement climatique gagne en magnitude et ajoute une pression supplémentaire sur les...

Les forêts humides sont parmi les écosystèmes humides les plus dégradés et les plus menacés dans le monde. En Algérie, elles représentent un ensemble d’habitats forestiers singuliers, fragiles et rares. La région d’El Kala, à l’extrême nord-est du pays, abrite de nombreuses zones humides uniques (lacs, marais, prairies humides, lagunes, etc.), parm...

Climate change is one of the strongest biodiversity threats. Worse still, the impact of multiple anthropic stressors on species dynamics could complicate adaptation to temperature increase. International conservation policies aim to protect ecosystems against anthropic pressures, but their ability to facilitate adaptation to climate change has yet...

Agricultural intensification over the past decades has led to a generalised decline in farmland biodiversity. Farmland birds are particularly exposed to rapid changes in habitat and reduced food resources or availability. Understanding how farmland specialists can be preserved and their populations enhanced are major challenges for this century. Ba...

The Mediterranean basin is extremely vulnerable to climate change, and one of the areas most impacted by human water demand. Yet the green roofs increasingly created both for aesthetic reasons and to limit pollution and urban runoff are themselves very water-demanding. Successful green roof installation depends on the establishment of the vegetatio...

The Mediterranean Waterbird Network works since 2012 on the improvement of the qulaity of data of waterbirds censuses in the North african region. The poster is about the success of the collaboration between the five north african countries and France but also on the potentiality of improvemnt of waterbird monitoring schemes and wetland conservatio...

It is currently recognized that vegetation is a crucial step in the installation of green roofs. This stage depends strongly on the substrate, without which the vegetation can only rarely establish. The substrate is thus probably the most important element of a green roof, providing moisture, nutrients and an essential physical support to plant spe...

The International Waterbird Census (IWC, coordinated internationally by Wetlands International), is one of the largest global biodiversity monitoring programmes. It contributes to the implementation of the African-Eurasian Waterbird Agreement (AEWA), the Ramsar Convention and the work of the Mediterranean Wetlands Observatory (MWO) as an advocacy t...

Connaitre la biodiversité d’un campus universitaire peut paraître bizarre voire inutile. Cependant, la vie est partout et dans n’importe quel milieu, même au sein d’une ville comme Montpellier. L’inventaire de la biodiversité de la Faculté de Sciences et Techniques est un projet innovant qui s’inscrit dans une politique de développement durable. Il...
