Testing urban edge effects: Nest predation rates are higher in areas further from the boundary of a suburban park
September 2025
Urban green spaces and parks offer opportunities for retaining and increasing bird richness, diversity, and species abundance. However, urbanisation influences predator–prey interactions, leading to...
Responses of steppe birds to habitat fragmentation: Insights from niche specialization and functional traits
September 2025
Habitat fragmentation poses a significant threat to bird communities, especially those in open and semi-open ecosystems such as steppes. This study investigates how steppe birds adapt to and utilize...
Climatic, topographic, and local-scale variables differently shape bird communities in urban streets and parks
September 2025
Green cover and human disturbance are important local factors shaping urban bird communities, while climatic and topographic variables can be important when analyzing cities in different biomes. However,...
Reconciling Bergmann's rule throughout the annual cycle in two congeneric large-bodied migratory waterbirds
September 2025
Bergmann's rule predicts that the larger of two homeotherm species differing only in size would occur at higher latitudes, or in cooler climates than the smaller, because of relative thermoregulatory...
Phylogeography of the endangered Yellow-headed Parrot (Amazona oratrix)
September 2025
Elucidating the historical processes that led populations to their current spatial and genetic arrangement is relevant in conserving threatened species. We interpreted the phylogeographic structure...
Highway effects on artificial nest survival in a neotropical sand-coastal plain: A spatiotemporal approach
September 2025
Roads are a leading cause of habitat fragmentation and may reduce bird populations by increasing nest predation rates. However, few studies have investigated the effects of traffic volume on the reproductive...
Variation of migration routes in the central Asian-breeding Common Cuckoo population influenced by the Qinghai-Tibet Plateau
September 2025
Ecological barriers present significant challenges to bird migration by limiting the availability of stopover sites and shelters. The Qinghai-Tibet Plateau, a major migratory barrier located in higher...
Sri Lanka's laughingthrush: An ecological and phylogenetic assessment of a babbler confused for a laughingthrush
September 2025
The Ashy-headed Laughingthrush (Argya cinereifrons), a species endemic to Sri Lanka, has been historically considered a laughingthrush in the genus Garrulax. However, based on phylogenetic evidence,...
From fledging to independence: Post-fledging movements and space use of the Crested Ibis (Nipponia nippon)
September 2025
The post-fledging period, extending from fledging to independence, is a crucial life stage characterized by high mortality due to fledglings' limited mobility and inexperience. During this stage, fledglings...
