Spatial structure could explain the maintenance of alternative reproductive tactics in tree cricket males

The paper uses a spatially explicit model to show spatial structure enables coexistence of alternative reproductive tactics in tree crickets by equalizing mating benefits.

Eco-evolutionary dynamics for finite populations and the noise-induced reversal of selection

This paper analytically describes eco-evolutionary dynamics in finite populations, showing how demographic noise can bias evolutionary trajectories opposite to natural selection.

Cooperation Destabilizes Communities, but Competition Pays the Price

The paper studies how external perturbations affect ecological communities, finding that cooperative interactions increase extinction risk but leave some species intact, leading to a community with more cooperation.

Allopatric montane wren-babblers exhibit similar song notes but divergent vocal sequences

The paper quantitatively analyzes song syntax divergence in montane wren-babblers, finding similar notes but divergent syntactic structures across geographic regions.

Behavioral context shapes vocal sequences in two anuran species with different repertoire sizes

This study examines how two frog species adjust their vocal sequences based on behavioral context, showing context-dependent modifications in vocal repertoires despite differences in repertoire size.

A colony-level optimization model provides a potential mechanism for the evolution of novel castes in eusocial ant colonies

The paper develops an economics-based optimization model to explain the evolution of novel castes in ant colonies, showing it aligns with empirical observations.
