Warm temperatures during cold season can negatively affect adult survival in an alpine bird
Ecology and Evolution, 2019 Climate seasonality is a predominant constraint on the lifecycles of species in alpine and polar biomes. Assessing the response of these species to climate change thus requires taking into account seasonal constraints on populations.

Social information about others' affective states in a human‐altered world
Journal of Animal Ecology, EarlyView.Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Corvid Cognition: Something to Crow About? [PDF]
Current Biology, 2015 New research indicates that crows are capable of matching stimuli on the basis of analogical relations: that is, similarity of size, color and shape. This may be the first evidence for spontaneous analogical reasoning outside of the primate order.

Animal WelfareThe activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their ...

Managing the Threat of Subsidized Predators for a Threatened Shorebird
Animal Conservation, EarlyView.Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators
Animal Conservation, EarlyView.We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

Ibis, EarlyView.The identification of key habitats of threatened species and of extrinsic environmental factors that influence their resilience to human‐induced environmental changes are the foundation for the definition of conservation objectives. Using the presence and numerical abundance data collected in a long‐term survey (2000–24) of breeding colonies of Lesser ...

Friends Aren’t Food: Pinyon Jays (Gymnorhinus cyanocephalus) Show Context-Dependent Quantity Preference [PDF]
Animal Behavior and CognitionAnimals must often choose between different quantities of objects in their environment, from food items to conspecifics. Yet we know little about how quantitative cognitive abilities compare across different types of objects.
