Seasonal habitat preference and foraging behaviour of post-moult Weddell seals in the western Ross Sea [PDF]

Royal Society Open Science, 2023
Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour.

Environmental cues rather than quality of supplemented pollen drive the foraging behaviour of honey bees during avocado pollination [PDF]

Scientific Reports
Honey bee colonies adapt their foraging behaviours to the availability of floral resources to meet their nutritional needs. However, it is unknown if the nutritional quality of stored or supplemented pollen can influence the floral choices of bees during

Linking ringed seal foraging behaviour to environmental variability [PDF]

Movement Ecology
Background Foraging rates directly influence animals’ energetic intake and expenditure and are thus linked to body condition and the ability to survive and reproduce.

Temperature-driven shifts in foraging behaviour during larval development in a dragonfly [PDF]

Scientific Reports
Predatory performance of dragonfly larvae is influenced by a multifaceted interplay of external factors such as temperature, prey density and interspecific competition, and life history traits like age and size.

Large‐Scale Passive Acoustic Monitoring Data Shows Seasonal and Diel Diversity in Foraging Behaviour of Harbour Porpoises Within Their Distributional Range in the Northeast Atlantic [PDF]

Ecology and Evolution
Latitudinal gradient can influence ecosystem dynamics and species distribution, yet the influence on some aspects, such as intra‐species diversity, is less well understood.

Ageing is associated with exaggerated overstaying in foraging behaviour. [PDF]

NPJ Aging
Abstract People constantly decide how much time to invest in rewarding activities. Foraging tasks assess this decision-making by measuring when individuals switch between contexts. People typically perform suboptimally in these tasks, largely due to overstaying, but it remains unclear whether this tendency changes with age independently of ...

Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses [PDF]

Movement Ecology, 2023
Background Animal movement data are regularly used to infer foraging behaviour and relationships to environmental characteristics, often to help identify critical habitat.

Post-foraging in-colony behaviour of a central-place foraging seabird

Scientific Reports, 2022
AbstractStudies on time allocation of various activities are crucial to understand which behavioural strategy is the most profitable in a given context, and so why animals behave in a particular way. Such investigations usually focus on a time window when the studied activity is performed, often neglecting how the time devoted to focal activity affects

A new way of assessing foraging behaviour at the individual level using faeces marking and satellite telemetry. [PDF]

PLoS ONE, 2012
Heterogeneity in foraging behaviour can profoundly influence ecological processes shaping populations. To scale-up from individual foraging behaviour to processes occurring at the population scale, one needs to sample foraging behaviour at the individual

Foraging parameters influencing the detection and interpretation of area-restricted search behaviour in marine predators: a case study with the masked booby. [PDF]

PLoS ONE, 2013
Identification of Area-restricted search (ARS) behaviour is used to better understand foraging movements and strategies of marine predators. Track-based descriptive analyses are commonly used to detect ARS behaviour, but they may be biased by factors ...
