Dear MARMAM colleagues,
We are pleased to announce our new publication:
Methion S, Giralt Paradell O, Padín XA, Corrège T, Díaz López B (2023). Group
size varies with climate and oceanographic conditions in bottlenose dolphins.
Marine Biology 170:7. Doi.org/10.1007/s00227-022-04154-4
AbstractAn understanding of animal grouping patterns is essential to increase
knowledge about their social systems. We used a five-year continuous dataset to
investigate grouping behavior in a free-ranging highly social mammal, the
bottlenose dolphin. Our objective was achieved by examining the relationships
between a set of oceanographic, climatic, topographic, anthropogenic and social
variables and bottlenose dolphin group size. Modeling analysis revealed that
bottlenose dolphin group dynamics was linked to both small-scale oceanographic
variation and large-scale climatic variation. Larger groups of bottlenose
dolphins were predicted with an elevated concentration of dissolved oxygen in
the water column, a moderate concentration of chlorophyll-a 60 days before each
encounter, and a neutral NAO index. The observed link between environmental
variables and dolphin group size is likely associated to changes in dolphin
prey availability. Bottlenose dolphin group dynamics are likely driven by
multiple factors, and social variables may act synergistically with
environmental parameters. Larger groups of bottlenose dolphins were indeed also
predicted with a greater number of dependent calves, likely because of enhanced
care towards the calves. This study illustrates the value of using multiple
variables at different scales to explore the factors that shape animal
societies. The current study therefore contributes to the growing body of
literature on how environmental change, occurring at different spatio-temporal
scales, is indirectly related to the social behavior of a marine top predator.
