Glacial cycles promote greater dispersal, which can help explain larger clutch sizes, in north temperate birds [PDF]
, 2009 Earth’s glacial history and patterns in the life history traits of the planet’s avifauna suggest the following interpretations of how recent geological history has affected these key characteristics of the biota: 1) Increased colonizing ...

Impact of hunting modality on social contacts in wild boar populations across Europe
Journal of Applied Ecology, Volume 63, Issue 1, January 2026.Our study showcases how hunting disturbance influences social contact rates in a group‐living wild mammal. Along with other biotic and abiotic drivers, hunting modality plays a significant role in shaping intra‐group, but not inter‐group, contacts. Reduced group cohesion induced by drive hunts could negatively impact survival, foraging efficiency and ...

Reproductive seasonality, sex ratio and philopatry in Argentina's common vampire bats
Royal Society Open Science, 2017 Common vampire bats (Desmodus rotundus) are a key rabies vector in South America. Improved management of this species requires long-term, region-specific information.

Decrease in Effective Population Size After the Immigration of Asian Black Bears to Japan
Ecological Research, Volume 41, Issue 1, January 2026.The Asian black bear populations in Japan experienced three distinct periods of population decline in the past. The first decline began approximately between 800,000 and 300,000 years ago, the second occurred around 150,000 to 70,000 years ago, and the third took place roughly from 50,000 to 18,000 years ago.

BMC Evolutionary Biology, 2010 Background It is hypothesized that one of the mechanisms promoting diversification in cichlid fishes in the African Great Lakes has been the well-documented pattern of philopatry along shoreline habitats leading to high levels of genetic isolation among ...

The Overlooked Threat of Global Warming on Elasmobranch Fertility
Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

The Evolution of Dispersal in Random Environments and The Principle of Partial Control [PDF]
, 2011 McNamara and Dall (2011) identified novel relationships between the abundance of a species in different environments, the temporal properties of environmental change, and selection for or against dispersal.

Ibis, Volume 168, Issue 1, Page 95-116, January 2026.Songbirds are a well‐established model group for the study of cultural evolution as their songs are learned (i.e. culturally transmitted), which may lead to divergence in song characteristics between populations. Song variation across populations may be affected by geographical isolation, timing and duration of the learning period, and life strategies ...
