To support sustainable growth of ocean-based economies, many countries are engaging in
marine spatial planning (MSP) processes, which require robust decision-support tools …

Although sexual dietary differentiation is well known in birds, it is usually linked with
significant morphological dimorphism between males and females, with lower differentiation …

Background Studies on animal behaviour often involve the quantification of the occurrence
and duration of various activities. When direct observations are challenging (eg, at night, in a …

Evolutionary biologists have long been interested in parsing out the roles of genetics,
plasticity and their interaction on adaptive trait divergence. Since males and females often …

Optimal foraging theory suggests that the environment (eg distribution of resource patches)
will shape an individual's decision to exploit the resource available or explore other …

Sex-specific niche differentiation is common in marine vertebrates, but how this varies long-
term is poorly understood. Here we investigated interannual variation in sexual segregation …

Ocean environments and associated biota are affected by wind. Expected future changes in
wind conditions could impact seabirds because they influence flight energetics. Seabird …

Highlights•Few studies have evaluated differences in foraging behaviour in monomorphic
species.•The gull-billed tern is a monomorphic seabird exploiting terrestrial …

During breeding, seabirds are central place foragers and are sensitive to changes in local
prey availability. As the breeding season progresses, foraging behavior and distribution is …

While differences in foraging and reproductive success are well studied between seabird
colonies, they are less understood at a smaller subcolony scale. Working with little penguins …
