Amazon mollies parasitize sperm from Atlantic mollies so why do Atlanics tolerate Amazons? Jon Aguinaga @jon_iguanas shows that Amazon mollies are better explorers under low risk - possibly providing useful info to other species, like Atlantic mollies. #ISBE2024

Where do big brains come from? Ghislaine Cardenas-Posada uses woodpeckers to show that species that retain big brains seem to evolve complex extractive foraging behaviors (to get yummy larvae), whereas species that lost their big brains lose this foraging strategy #ISBE2024

Jay Gallagher @arpeggio_jay shows that despite strong threat of predation, clonal fish still develop strong individuality in their behavior. There is no way one way to be a fish! #ISBE2024

Climate change is expanding breeding seasons so what do parents do to take advantage of this? Davide Baldan shows rock sparrow males start (& desert) more nests whereas females sequentially complete several nests. #ISBE2024

Mongeese need to defend their territories. Territory edges are hotly contested and Josh Arbon shows they adjust their behavior not just as chance of conflict with other groups goes up, but especially if those other groups are extra threatening (bigger). #ISBE2024

Annemarie van der Marel show that "key" (more highly connected) individuals in degu groups are typically male and more involved in affecting between-group interactions than within-group interactions #ISBE2024

Dominance hierarchies are stable but which individuals end up in which rank? Kirsten Sheehy disentangle size from familiarity - size helps in unfamiliar groups, but it won't guarantee your success in established groups. #ISBE2024

How do friendships form? Gerry Carter shows that individual traits can sort of predict initial interactions but ultimately continued social history overshadows this "first impression". It's difficult to predict who will be friends for life! #ISBE2024

@GraceHDavis asks why form big groups when resources are scarce. Won't this lead to more competition? But classic foraging theory shows that's consensus costs reduce when groups get bigger making it pay to hang around all these competitors #ISBE2024
