Intraspecific variability in feather moult extent declines under both low and high constraints
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variability (ITV) is a fundamental feature of biological populations and the raw material upon which natural selection acts, yet its drivers remain poorly understood.

Scientific Reports, 2019 Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity of data on closely related species, especially those spanning broad environmental gradients.

Flight Behavior of Individual Aerial Insectivores Revealed by Novel Altitudinal Dataloggers
Frontiers in Ecology and Evolution, 2018 Swallows and martins (Aves: Hirundinidae) are well-studied with respect to their breeding biology, but major aspects of their individual aerial movement behavior and ecology are poorly understood.

Integrative Zoology, EarlyView.Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Spatial and Seasonal Variation in Avian Dietary Strategies
Global Ecology and Biogeography, Volume 35, Issue 7, July 2026.ABSTRACT Aim Diet is a fundamental aspect of vertebrate life history, shaping survival, recruitment, and fitness. While spatial variation in avian dietary characteristics has been studied, seasonal dynamics at species and assemblage levels remain largely unexplored, hindering our understanding of biodiversity patterns and processes.

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology
Austral Ecology, Volume 51, Issue 6, June 2026.ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.

Strukturierungsmechanismen der Crematogaster-Macaranga Ameisen-Pflanzen Assoziationen : ein kombinierter ökologischer und phylogenetischer Ansatz [PDF]
, 2003 One of the most species-rich ant-plant mutualisms worldwide is the palaeotropical Crematogaster-Macaranga system. The pioneer-tree genus Macaranga (Euphorbiaceae) is mainly inhabited by at least nine specific species of Crematogaster (Myrmicinae), of ...

Case of human infestation with dermanyssus gallinae (Poultry red mite) from swallows (hirundinidae) [PDF]
, 2021 Dermanyssus gallinae (the poultry red mite, PRM) is an important ectoparasite in the laying hen industry. PRM can also infest humans, causing gamasoidosis, which is manifested as skin le-sions characterized by rash and itching.
