Variation in forest area influences post‐fledging development and dispersal onset in the Eurasian Goshawk (Astur gentilis)

Ibis, EarlyView.
Natal dispersal is a key ecological process influencing gene flow, population connectivity and individual fitness. In altricial birds, the transition from fledging to natal dispersal is mediated by the post‐fledging dependence period, which is often difficult to observe in elusive, forest‐dwelling species.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

High‐throughput tracking reveals differences in low‐tide space use between day and night in wintering Red Knots

Ibis, EarlyView.
Within intertidal ecosystems, the availability of foraging areas for shorebirds changes rapidly with the tidal cycle, imposing a strict regime of foraging opportunity. Several shorebird species have been reported to forage during both diurnal and nocturnal low‐tide periods, making the most of available foraging times, but detailed descriptions of ...

A global overview of pigeon–fruit interactions

Ibis, EarlyView.
Pigeons are widespread worldwide. These relatively large‐bodied birds can significantly influence ecosystem structure and function through their feeding habits, especially on islands where large mammals and a few avian taxa are scarce or absent. However, their dietary guilds as frugivores and granivores, and their ecological roles as seed dispersers ...

Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

Insect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.
