Intraspecific variability in feather moult extent declines under both low and high constraints

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2350-2362, August 2026.
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.

Strukturierungsmechanismen der Crematogaster-Macaranga Ameisen-Pflanzen Assoziationen : ein kombinierter ökologischer und phylogenetischer Ansatz [PDF]

open access: yes, 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 ...

Spatial and Seasonal Variation in Avian Dietary Strategies

open access: yesGlobal 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.

Temperate-Tropical Variation in Breeding Synchrony and Extra-Pair Paternity Among New World Tachycineta Swallows

open access: yesScientific 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.

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology

open access: yesAustral 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.
