Dear MARMAM community, On behalf of my co-authors, I am pleased to share our latest research, published in Royal Society Open Science, with you. Berthelsen, A.L., Bartl, J., Winterl, A., Fox-Clarke, C., Forcada, J., Nagel, R., et al. (2026). Fine-scale spatiotemporal predator-prey interactions in an Antarctic fur seal colony. R. Soc. open sci., 250931 DOI: 10.1098/rsos.250931 Abstract: Density is a major determinant of population dynamics, with high densities exacerbating intraspecific competition and disease transmission while low densities increase predation risk. To investigate spatiotemporal density patterns and predator–prey interactions in a breeding colony of Antarctic fur seals (Arctocephalus gazella), we deployed an autonomous camera capturing minute-by-minute, high-resolution images throughout a breeding season. Using a YOLO-based neural network, we identified adult males, females and pups, as well as three avian predator–scavengers: giant petrels (Macronectes spp.), brown skuas (Stercorarius antarcticus) and snowy sheathbills (Chionis alba). Analysis of 4.1 million automated detections from over 10 000 high-quality images revealed spatiotemporal abundance patterns corresponding with the known breeding and foraging behaviours of these species. Strong temporal associations emerged between the abundance of pups and two avian species, while fine-scale spatial analyses showed that pups grouped together with other pups and adult females but avoided avian predators and territorial males. Notably, proximity to adult fur seals of both sexes reduced pup predation risk, defined as the distance between the pup and the nearest bird, whereas proximity to other pups did not. Overall, this study provides a framework for quantifying density-dependent interactions in wild populations and emphasizes the value of remote observation in ecological research.
