The installation of nestboxes is a widely used conservation measure for enhancing habitat suitability for cavity-nesting birds wherever natural holes are scarce. However, nestboxes may attract birds to unsuitable breeding places or induce a non-[...]

Human depopulation of rural mountain areas and the consequent abandonment of traditional land management are among the greatest driving forces behind changes in mountain ecosystems in Western Europe. Tree and shrub encroachment lead to an increa[...]

Studying a species under a range of conditions is essential for fully understanding its ecology and for predicting its response to human impacts on the environment. We investigated the spatial behaviour and the habitat characteristics of foragin[...]

The Eurasian Bittern Botaurus stellaris suffered declines in western Europe during the 20th century, partly because of wetland reclamation. The species has been traditionally considered a reedbed specialist but recent studies identified a greate[...]

Rice fields are an important habitat for waterbirds. Knowledge of the availability of this habitat is important since the reduction in the area of natural wetlands has converted rice fields into vital refuges. This paper presents a method for ma[...]

Many species of waterfowl undergo a post-breeding simultaneous flight feather moult (wing moult) which renders them flightless and vulnerable to predation for up to 4 weeks. Here we present an analysis of the correlations between individual time[...]

Birds in the northern hemisphere usually increase mass reserves in response to seasonal low temperatures and shorter day length that increase foraging unpredictability and so starvation risk. In the lowland tropics, relatively low temperatures a[...]

Many highly invasive plants are fleshy-fruited and owe their invasiveness largely to mutualisms formed with local dispersers. The energetic benefits gained by frugivores from ingestion of fruits of invasive alien plants remain poorly documented.[...]

Variations in visual field topography among birds have been interpreted as adaptations to the specific perceptual challenges posed by the species' foraging ecology. To test this hypothesis we determined visual field topography in four bird speci[...]

To assess the benefits of nesting at a site hidden from neighbours in a loosely colonial species, the Barn Swallow Hirundo rustica, we carried out two field experiments, obstruction removal and mirror placement, both replicating a situation in w[...]

Survival typically contributes most to population trends in long-lived birds and its accurate estimation is therefore vital for population management and conservation. We evaluated the effects of age, territoriality and reproduction on survival [...]

Unravelling the contributions of density-dependent and density-independent factors in determining species population dynamics is a challenge, especially if the two factors interact. One approach is to apply stochastic population models to long-t[...]

Animals can select breeding sites using non-social information (habitat characteristics) and social information (conspecific presence or abundance). The availability of both types of information is expected to vary over time during the colonizat[...]

Spatiotemporal variation in survival may be an important driver of multi-population dynamics in many wild animal species, yet few scientific studies have addressed this issue, primarily due to a lack of sufficiently comprehensive and detailed da[...]

Structural variation in acoustic signals may be related either to the factors affecting sound production such as bird morphology, or to vocal adaptations to improve sound transmission in different environments. Thus, variation in acoustic signal[...]

Vicariance and dispersal in the differentiation of vocalization in the Ryukyu Scops Owl Otus elegans
Masaoki Takagi, Auteur
The distribution of species and species diversity can be affected by vicariance or dispersal. To understand their role in shaping species distribution and population structure these two processes must be estimated within and among populations. I[...]

Quantifying population genetic structure is fundamental to testing hypotheses regarding gene flow, population divergence and dynamics across large spatial scales. In species with highly mobile life-history stages, where it is unclear whether suc[...]

The Sahara desert acts as an ecological barrier for billions of passerine birds on their way to and from their African wintering areas. The Garden Warbler Sylvia borin is one of the most common migrants involved. We used body mass of this specie[...]
