Spatio-temporal patterns of juvenile common ravens integrating into a free-flying non-breeder flock

iScience
For animals living in structured groups, social integration matters: numerous studies reveal fitness advantages for well-integrated over poorly integrated individuals.

Evolutionary Biology Needs Wild Microbiomes

Frontiers in Microbiology, 2017
The microbiome is a vital component to the evolution of a host and much of what we know about the microbiome derives from studies on humans and captive animals.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Îles à la dérive, entre écopoétique et géopolitique

Revue LISA
Islands in the Stream, a posthumously reconstructed novel, subtly combines a strong ecopoetic dimension with an evocation of Hemingway’s involvement in the Second World War.

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

Journal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Estimating demographic parameters using a combination of known-fate and open N-mixture models

, 2015
1. Accurate estimates of demographic parameters are required to infer appropriate ecological relationships and inform management actions. Recently developed N-mixture models use count data from unmarked individuals to estimate demographic parameters, but

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.
