Frontiers in Ecology and Evolution, 2015 Changes in the timing of migratory events have been observed recently in many migratory species, most likely in response to climatic change. In the common tern Sterna hirundo we examined such changes in spring arrival date and body mass based on a 19 ...

Record phenological responses to climate change in three sympatric penguin species
Journal of Animal Ecology, EarlyView.This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Seabirds as a subsistence and cultural resource in two remote Alaskan communities
Ecology and Society, 2014 Small rural Alaskan communities face many challenges surrounding rapid social and ecological change. The role of local subsistence resources may change over time because of changes in social perception, economic need, and cultural patterns of use.

Methods in Ecology and Evolution, EarlyView.Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Methods in Ecology and Evolution, EarlyView.Abstract Quantifying the structure and dynamics of species interactions in ecological communities is fundamental to studying ecology and evolution. While there are numerous approaches to analysing ecological networks, there is not yet an approach that can (1) quantify dissimilarity in the global structure of ecological networks that range from ...

Leveraging machine learning and accelerometry to classify animal behaviours with uncertainty
Methods in Ecology and Evolution, EarlyView.Abstract Animal‐worn sensors have revolutionised the study of animal behaviour and ecology. Accelerometers, which measure changes in acceleration across planes of movement, are increasingly being used in conjunction with machine learning models to classify animal behaviours across taxa and research questions.

Biodiversity research requires more motors in air, water and on land
Methods in Ecology and Evolution, EarlyView.Abstract Human activities have accelerated species extinctions, driving rapid biodiversity decline. Simultaneously, advancements in Artificial Intelligence (AI) and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—drones (aerial systems) and other robots (ground and underwater platforms)—equipped with high ...

Northern Gannet foraging trip length increases with colony size and decreases with latitude
Royal Society Open ScienceDensity-dependent competition for food influences the foraging behaviour and demography of colonial animals, but how this influence varies across a species’ latitudinal range is poorly understood.

Isolating Mechanisms in Seabirds [PDF]
Evolution, 1987 In most species of birds, differences in plumage coloration or song structure act as isolating mechanisms. In seabirds, plumages are generally drab, and vocal repertoires are limited so that other phenotypic attributes must act as isolating mechanisms.
