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.

Leadership and information transfer in groups escaping a (simulated) threat in the wild

The paper studies how blackbuck groups respond to a simulated threat, finding that leadership emerges during escape and that rear individuals influence group movement.

Characterising the vegetation-rainfall relationship in the Northeast Himalaya, India

The paper constructs a vegetation state diagram for Northeast India using satellite data and rainfall measurements, finding no bimodal distribution in vegetation cover as rainfall increases.

Multi-Object Tracking in Heterogeneous environments (MOTHe) for animal video recordings

MOTHe is an open-source tool for tracking multiple animals in natural habitats using a convolutional neural network, demonstrating effectiveness on videos of wasps and antelope.

Clustering and correlations: Inferring resilience from spatial patterns in ecosystems

This paper examines the relationship between spatial clustering patterns and ecosystem resilience, finding that power-law clustering does not reliably indicate ecosystem thresholds or collapse.

Dispersal increases the resilience of tropical savanna and forest distributions

The paper uses a reaction-diffusion model to show that dispersal contributes to the spatial distribution of savanna and forest, with boundary dynamics influenced by precipitation and history.

Mobility can promote the evolution of cooperation via emergent self-assortment dynamics

This paper shows mobility can promote cooperation by enabling self-assortment of cooperators in dynamic populations without requiring information about others' traits or strategies.
