1. The exponential development of wind energy raises concerns regarding its impacts on airborne biodiversity. Evidence of wind turbine attraction and repulsion on bats, and underlying collision risks and habitats losses, are increasingly reported. Since bat activity strongly decreases with distance to optimal habitats such as woody edges, we hypoth...

Among the most prevalent sources of biodiversity declines, Artificial Light At Night (ALAN) is an emerging threat to global biodiversity. Much knowledge has already been gained to reduce impacts. However, the spatial variation of ALAN effects on biodiversity in interaction with landscape composition remains little studied, though it is of the utmos...

Aim Animal movement determines home range patterns, which in turn affect individual fitness, population dynamics and ecosystem functioning. Using temperate bats, a group of particular conservation concern, we investigated how morphological traits, habitat specialization and environmental variables affect home range sizes and daily foraging movement...
Article
Landscape simplification and degradation through agricultural intensification is widely recognized as a main driver of biodiversity loss. In intensively used agricultural landscapes, patches of semi-natural habitats and particularly connections between them are of high importance for many taxa. Vegetated connections like hedgerows are especially im...

Artificial light at night (ALAN) is nowadays recognized as a major anthropogenic pressure on the environment on a global scale and as such is called light pollution. Through its attractive or deterrent effects, and its disruption of the biological clock for many animal and plant taxa, ALAN is increasingly recognized as a major threat to global biod...

Passive Acoustic Monitoring offers promising opportunities for biodiversity assessments and species conservation and is still in development. The robustness of community metrics depends on sampling effort, and acoustic surveys should be adjusted for cost-effectiveness. Using a large-scale acoustic survey of bat assemblages conducted along 5,487 sur...
Article
The goal of the mitigation hierarchy is to counteract the losses of biodiversity due to development projects by avoiding, reducing and as a last resort, by offsetting these losses. However, the implementation of offset measures is currently very unsatisfactory from a biodiversity perspective, and many development projects do not incorporate them. H...

Background: Artificial light at night is recognized as an increasing threat to biodiversity. However, information on the way highly mobile taxa such as bats spatially respond to light is limited. Following the hypothesis of a behavioural adaptation to the perceived risks of predation, we hypothesised that bats should avoid lit areas by shifting the...
Article
Artificial light at night (ALAN) is considered as a major threat to biodiversity, especially to nocturnal species, as it reduces availability, quality and functionality of habitats. However, its effects on the way species use landscape elements such as rivers are still largely understudied, especially the effect of crossing infrastructure lighting...

1. In cities, trees planted along streets could play an important ecological role for spontaneous plants growing at their bases. For example, these trees could represent corridors by potentially connecting large green spaces (e.g., parks, gardens), which allow species to move within the urban matrix. We considered sets of urban trees in 15 streets...
Article
The development of transportation infrastructure has been identified as one of the main pressures on biodiversity. The effects of transport infrastructure are more documented for terrestrial mammals, birds and amphibians than for bats. To assess the impacts of roads on bat activity, we carried out full-night acoustic recordings of bat calls at 306...

Article
This addendum is motivated by criticisms of the concerned paper by wind developers who raised a potential altitude bias, wind turbines being most often positioned higher than their surrounding environment. Despite altitude vary very little in the study area, we believed it was valuable to control for this potential confounding effect and thus to en...

1.Assessing the state and trend of biodiversity in the face of anthropogenic threats requires large‐scale and long‐time monitoring, for which new recording methods offer interesting possibilities. Reduced costs and a huge increase in storage capacity of acoustic recorders has resulted in an exponential use of Passive Acoustic Monitoring (PAM) on a...

Article
Wind energy is rapidly growing as a renewable source of energy but is not neutral for wildlife, especially bats. Whereas most studies have focused on bat mortality through collision, very few have quantified the loss of habitat use resulting from the potential negative impact of wind turbines, and none of them for hub heights higher than 55 m. Such...

Abstract Many studies have shown that the quality of biodiversity influences the well-being of citizens. Nevertheless, the drivers that shape biodiversity in urbanized zones are poorly understood. Although tree bases present reduced surface areas, they occur in great numbers in a deliberate spatial arrangement and may play an important ecological r...

The increased use of pesticides and tillage intensification is known to negatively affect biodiversity. Changes in these agricultural practices such as herbicide and tillage reduction have variable effects among taxa, especially at the top of the trophic network including insectivorous bats. Very few studies compared the effects of agricultural pra...
Thesis
Full-text available
Land-use planning and agricultural intensification are two major causes of biodiversity loss. Most of development projects have to apply the mitigation hierarchy, i.e. avoid, reduce then offset impacts on biodiversity, in order to achieve the no net loss. Wind farm installation makes the mitigation hierarchy application difficult due to the lack of...

In a European collapse context of many farming species, solutions should be found to stop these losses. Due to intensification of the most part of agriculture, improvements are easily accessible such as input and soil tillage reduction. Such changes are known to have positive effects on biodiversity. However, in some cases negative effects are dete...

Biodiversity is being lost at an increased rate as a result of human activities. One of the major threats to biodiversity is infrastructural development. Although the measures taken in environmental impact assessments can limit this loss, the mitigation hierarchy to "Avoid, Reduce and Offset" impacts on biodiversity is not fully functional. Indeed, the mitigation hierarchy often uses qualitative data and does not account for the biological and/or ecological processes and their different spatial and temporal scales. The impact of roads is well documented for several biological groups but not for bats whereas they are likely to be very strongly affected. Moreover, as they are strictly protected, they should be considered in the mitigation hierarchy. Therefore, through the study of bats, I investigated the effects of roads, especially major roads, and intended to measure and quantify the magnitude of their impacts. This thesis presents different methods developed to reach this objective and which may be used by stakeholders in the field. First, I intended to determine how to process data collected through passive acoustic monitoring and how to exploit these data. Then I determined what the impacts of roads on bat populations are and I proposed a method in order to assess the mitigation measures which presume to restore bat habitat connectivity. Our main results show a significant negative effect of roads on bats foraging and commuting behaviour for several species and up to at least five kilometres away from a major road. In addition, the effect of major roads also seems to have consequences on populations’ genetics. Finally, we studied bat overpasses which are structures specifically dedicated to bats and aiming at reducing the impacts of roads by improving bats’ habitat connectivity. These structures seem to be appropriate when located in narrow ecological corridors such as hedgerows.

Les espèces volantes, notamment les chauves-souris et les oiseaux, rencontrent des obstacles particuliers situés dans la strate aérienne (éoliennes, lignes électriques, bâti élevé, aéronefs, ...). Des problématiques spécifiques se posent pour la gestion de ces obstacles et l'identification de voies de déplacement sécurisées dans l'air sous le nom de Trame aérienne.
Project
This project aims to study the impact of Artificial Light at Night (ALAN) on the behaviour and activity of bats. I mainly focus my research on the variability of such impacts according to urban-rural landscape compositions. I also study the behavioural response to the proximity of lights combining spectrum and intensity variables, using new methods such as the trajectography in 1 and 3 dimensions from acoustic data.
