Article
Conventional farming has been implicated in global biodiversity loss, with many farmland birds in decline. Organic farming is often considered a more ecological alternative since it generally hosts greater faunal diversity. To date, the impact of conventional agriculture on the decline in avian species has mainly been assessed through the lens of b...

Full-text available
The last century has seen a steep decline in biodiversity, and anthropization is considered one of the major drivers of this decline. Anthropogenic disturbances, due to human presence and/or activities, may be perceived as chronic stressors by wildlife and potentially lead to deleterious effects on traits related to fitness. The main objective of t...

Context Recognized as a critical ecosystem service in farmland, pollination is threatened by the decline of pollinators, notably due the homogenization of the landscape and the decline of floral resources. However, there is still a limited understanding of the interplay between landscape features and the pulses of floral resources provided by mass-...
Article
Agricultural intensification tends to maximize provisioning services at the expense of regulating, cultural and supporting ecosystem services (ES). Enhancing agroecosystem sustainability requires both individual and collective solutions, but these are particularly difficult to design and implement since knowledge is lacking and ES may be considered...
Article
Pollination and pest control are two major ecological functions sustaining crop yield. In insect‐pollinated crops, previous studies have revealed that an increase of resources and habitats in landscapes can increase pest control by natural enemies as well as insect pollination by pollinators. However, data has been lacking that simultaneously consi...
Article
Although Glyphosate-based herbicides are often marketed as environmentally friendly and easily biodegradable, its bioavailability and risks to wildlife raise significant concerns. Among non-target organisms, earthworms which live in close contact with the soil can be directly exposed to pesticides and harmed. We investigated soil contamination and...

We present evidence that confirms the streaked Fregetta lineata is a valid extant species that breeds on New Caledonia and endorse the vernacular name New Caledonian Storm Petrel. We review taxonomic deliberations over the historic five ‘Pealea’ streaked storm petrel specimens. Three belong to the recently rediscovered New Zealand Storm Petrel F. m...
Article
Predation is a major evolutionary force in animal ecology. Mechanisms by which prey coloration provides camouflage has been widely studied. However, predator response to prey camouflage and concealment has received less attention. Understanding vegetation structure effect on depredation success could help managers design strategies to mitigate the...
Chapter
In this closing chapter, we synthesize the most relevant results presented in this volume and discuss research and conservation prospects for the little bustard. Research should focus on unexplored areas of little bustard biology and ecology, such as sensorial perception, physiological trade-offs related to sexual selection and reproductive investm...
Chapter
Despite conservation efforts made over three decades and the improvements in protection status at different levels (global, European, national and regional), the current situation of the little bustard has not improved. Increased knowledge on the species’ biology, and projects aimed at improving its conservation status, such as the designation of p...
Chapter
In this chapter, we focus mainly on the behavioural ecology of the little bustard (i.e. how behaviour relates to ecology and evolution), with particular emphasis on breeding behaviour, sexual selection and mating systems, as well as their relevance for little bustard conservation. We discuss the evolutionary forces that drive the species’ lekking b...
Chapter
The little bustard is distributed over an extensive Palearctic range from north-western Africa and Iberia to central Asia, encompassing France, Italy, southern Russia and the Middle East. Over such a vast region, it occupies natural grass steppes, pastured grasslands and cereal farmland, avoiding extreme climatic conditions. Nowadays, two main dist...
Chapter
The little bustard Tetrax tetrax is one of the smallest members of the family Otididae, and has many remarkable life history traits, in its anatomy, biology and ecology. Some of them are shared with other bustard species, but others are unique to the little bustard. In this chapter we first describe plumage and biometry. Moreover, we present and ex...
Chapter
We summarize what is known about the variation in little bustard (Tetrax tetrax) vital parameters across its distribution range, regarding densities, breeding phenology, nesting and brooding, breeding success and sex ratio, as well as chick and adult survival. Breeding densities are highly variable, but generally higher in non-intensified farmland...
Chapter
Little bustard seasonal movements are complex. Besides the long known fully long-distance migratory populations (i.e. those of western France, Russia, and Central Asia), there are also others fully migratory that perform shorter migrations, such as many from northern Spain, or partially migratory, such as those from central Spain. Moreover, there a...

The use of pesticides in agriculture to protect crops against pests and diseases generates environmental contamination. The atmospheric compartment contributes to their dispersion at different distances from the application areas and to the exposure of organisms in untreated areas through dry and wet deposition. A multiresidue analytical method usi...

Full-text available
Aim Palaeoceanographic changes can act as drivers of diversification and speciation, even in highly mobile marine organisms. Shearwaters are a group of globally distributed and highly mobile pelagic seabirds. Despite a recent well-resolved phylogeny, shearwaters have controversial species limits, and show periods of both slow and rapid diversificat...
Article
Full-text available
Behavioral adjustments are of critical importance for the survival of animals when exposed to risk and resource variations in their environment. Moving to safer habitats allows prey to reduce the risk of mortality triggered by predation. This response has been well studied at the population level to assist in identifying key habitat components for...
Article
Full-text available
Seabirds, particularly Procellariiformes, are highly mobile organisms with a great capacity for long dispersal, though simultaneously showing high philopatry, two conflicting life-history traits that may lead to contrasted patterns of genetic population structure. Landmasses were suggested to explain differentiation patterns observed in seabirds, b...
Article
Individuals´ distribution across habitats may depend on their personality. Human activities and infrastructures are critical elements of the landscape that may impact the habitat selection process. However, depending on their personality, individuals may respond differently to these unnatural elements. In the present study, we first investigated wh...
Article
The little bustard is an iconic species, indicator of healthy grassland and farmland ecosystems. It formerly ranged almost continuously from north-western Africa and Iberia to central Asia, encompassing France, Italy, southern Russia and the Middle East, occupying natural grass steppes, pastured grasslands and extensive cereal farmland. Today, two...

Substitution rate variation among branches can lead to inaccurate reconstructions of evolutionary relationships and obscure the true phylogeny of affected clades. Body mass is often assumed to have a major influence on substitution rate, though other factors such as population size, life history traits, and flight demands are also thought to have a...
Article
Pterodroma leucoptera caledonica is a subspecies of Gould’s Petrel endemic to New Caledonia. Its distribution, abundance and breeding biology are poorly known. Extensive surveys of New Caledonia between 1994 and 2014 located only two breeding colonies, and a further likely, but still unconfirmed; the total estimated size of the population could be...
Article
In human-dominated landscapes, human disturbances may contrast (spatially and/or temporally) with risk imposed by non-human predators. However, how prey adjust behaviour to minimize risk from multiple threats remains unclear. In Central-Western France, we investigated patterns of activity, space and habitat use, and causes of variations during the...
Article
Farmland birds are declining across Europe and North America and the research of factors behind is the subject of extensive researches. Agricultural intensification is now recognized as a major factor governing the loss of biodiversity with strong evidence that pesticides induced direct bird mortality at a high dose. However, less attention has bee...
Article
Full-text available
Managing regulating ecosystem services delivered by biodiversity in farmland is a way to maintain crop yields while reducing the use of agrochemicals. Because semi-natural habitats provide shelter and food for pest enemies, a higher proportion of semi-natural habitats in the landscape or their proximity to crops may enhance pest control in arable f...
Article
Behavioural combination within pairs depending on personality and plasticity might influence reproductive success. However, studies testing this hypothesis are rare, especially in the case of monogamous species with bi-parental care in which the sexes exhibit different behavioural roles. In this study, we investigated the pairing patterns for both...

Full-text available
The diversification of modern birds has been shaped by a number of radiations. Rapid diversification events make reconstructing the evolutionary relationships among taxa challenging due to the convoluted effects of incomplete lineage sorting (ILS) and introgression. Phylogenomic datasets have the potential to detect patterns of phylogenetic incongr...

As top predators, seabirds are directly impacted by any changes in marine communities, whether they are linked to climate change or caused by commercial fishing activities. However, their high mobility allows them to adapt to changing conditions. For example, seabirds can adapt their foraging behaviour according to the resources available at differ...
Article
Critical knowledge gaps about environmental fate and unintentional effects of currently used pesticides (CUPs) hamper the understanding and mitigation of their global impacts on ecological processes. We investigated the exposure of earthworms to 31 multiclass CUPs in an arable landscape in France. We highlighted the presence of at least one pestici...

Full-text available
Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15–91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. We test whether (i) local lo...
Article
Arable weeds are key organisms for biodiversity maintenance and ecosystem service provision in agroecosystems. Disentangling the drivers of weed diversity is critical to counteract the global decline of farmland biodiversity. Even if distinct scale-dependent processes were alternatively proposed, no general framework unifying the multi-scale driver...
Data
A species-rich weed community in South France, photographed in May 2018. It shows some threatened weeds of Mediterrean origin, but also the high temporal variability of these communities: in 2018, the rainy winter and spring allowed very high density of weeds in cultivated fields and fallows of the area, while most of the time the weed populations...
Article
Interspecific competition is expected to occur between phylogenetically closely related species when sharing resources. In birds, interspecific competition often occurs by song-mediated interference and frequently implies asymmetrical outcomes between the species pairs involved. Habitat loss resulting from agricultural intensification is expected t...
Article
Nest predation is a major cause of reproductive failure in birds, but predator identity often remains unknown. Additionally, although corvids are considered major nest predators in farmland landscapes, whether breeders or floaters are involved remains contentious. In this study, we aimed to identify nest predators using artificial nests, and test w...
Article
Full-text available
The definition of “arable weeds” remains contentious. Although much attention has been devoted to specialized, segetal weeds, many taxa found in arable fields also commonly occur in other habitats. The extent to which adjacent habitats are favourable to the weed flora and act as potential sources of colonisers in arable fields remains unclear. In a...
Article
Agricultural intensification is one of the main drivers of species loss worldwide, but there is still a lack of information about its effect on functional diversity of arable weed communities. Using a large scale pan European study including 786 fields within 261 farms from eight countries, we analysed differences in the taxonomic and functional di...

1. Measuring time‐activity budgets over the complete individual lifespan is now possible for many animals with the recent advances of life‐long individual monitoring devices. Although analyses of changes in the patterns of time‐activity budgets have revealed ontogenetic shifts in birds or mammals, no such technique has been applied to date on insec...
Article
Full-text available
The current challenge in agriculture is to move from intensively managed to multifunctional agricultural landscapes that can simultaneously provide multiple ecological functions (multifunctionality), thus ensuring the delivery of ecosystem services important for human well-being. There is evidence that biodiversity is the main driver of multiple ec...

Article
Addressing the question of the parental effort allocation when breeding remains central to life-history theory. This is particularly the case for monogamous species with obligate bi-parental care, where each parent should evaluate its contribution throughout the breeding season taking into account both the effort of its mate and environmental const...
Article
Land-use change is a major driver of biodiversity loss worldwide. Although biodiversity often shows a delayed response to land-use change, previous studies have typically focused on a narrow range of current landscape factors and have largely ignored the role of land-use history in shaping plant and animal communities and their functional character...
