The Interactive Effects of Annual Climatic Variability and Rangeland Management on the Reproductive Success of Dickcissels (Spiza americana) [PDF]

, 2017
Grassland songbird populations have declined due to poor rangeland management and habitat fragmentation. Few studies have taken into account variation in climatic conditions in tallgrass prairie systems when determining the factors contributing to ...

The Human Threat From West Nile Virus and Usutu Virus in a Changing Climate

APMIS, Volume 134, Issue 5, May 2026.
ABSTRACT In recent years, the closely related arboviruses West Nile virus (WNV) and Usutu virus (USUV) have spread farther north in Europe. The viruses often co‐circulate and are maintained in a natural cycle between ornithophilic mosquitoes and birds.

Long‐Term Trends of Adult Survival and Productivity in European Songbirds: Role of Migration Strategy and Temperature Gradient Within Species' Ranges

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim To understand species population ecology, we need to study how trends of demographic drivers change over time and space, especially so under current rapid climate change. However, knowledge on long‐term trends of survival and productivity, especially using multiple species over large spatial scales, is scarce.

Inferring Time‐to‐Speciation From Hybrid Zone Analysis Informs Assessments of Taxonomic Inflation

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Measuring gene flow across hybrid zones can provide a direct evaluation of reproductive isolation (RI) between evolutionary divergent lineages. Geographic‐explicit modelling of gene flow across hybrid zones, known as cline analysis, thus offers a gold standard for species delimitation under the biological species criterion.

A Feasibility Study of Using Unmanned Aerial Vehicles to Survey Avian Abundance by Using Audio Recording

, 2015
Roadside counts are commonly used to assess songbird abundance, but they result in oversampling habitat edges and underrepresenting core habitats, areas of steep terrain, and wetlands.

Stable immune function during moult regardless of age‐specific moulting strategy in a European passerine

Journal of Avian Biology
Moult, the regular replacement of feathers, is a resource‐intense avian annual‐cycle stage. Resource allocation to support feather regrowth may require downregulation of other physiological processes, such as immune function, which is critical for ...
