This study investigates whether close intraspecific encounters lead to long-term spatial shifts in animal home ranges using movement data from coyotes and grizzly bears.

This study introduces a spatially-explicit framework to analyze how aggregation and component Allee effects influence population dynamics and survival.

This paper develops a model to assess the evolutionary stability of antagonistic facilitation in plants under environmental stress and finds it is stable in highly stressful conditions.

This study analyzes GPS data from 1,396 terrestrial mammals across 62 species to show how predator-prey dynamics influence movement strategies and resource search efficiency.

This study shows that fragmentation and foraging behavior jointly affect predator-prey dynamics and ecosystem stability in fragmented landscapes.

The paper uses remote-sensing data to show slowing down in dryland vegetation patterns as they transition from gaps to spots under arid conditions, confirming predictions of critical slowing down.

This paper introduces a new theoretical framework to estimate encounter location probabilities from animal tracking data and demonstrates its application using GPS data from capuchins and lizards.

This study uses a noisy voter model to examine species competition, showing outcomes like exclusion, mono-stable, and bi-stable coexistence depending on immigration and competition-dispersal tradeoffs.

This paper investigates eco-evolutionary feedbacks in prey-predator systems with spatial constraints, showing that predator perceptual range evolution influences species coexistence and extinction probabilities.

The paper derives analytical expressions for encounter rates under Ornstein-Uhlenbeck motion and compares them to Reflected Brownian Motion, showing that neglecting realistic movement and perceptual behaviors can bias encounter rate predictions.

This study characterizes the gut microbiome of adult tropical gar fish, identifying core phyla and potential probiotic strains by sex and origin.

The paper identifies heritable loner behavior in Dictyostelium discoideum, showing it arises from stochastic signaling decisions and environmental factors, with implications for ecological and evolutionary dynamics.

This study investigates how cell adhesion and fluid flow influence genotype spatial distribution in biofilms using Vibrio cholerae, finding that adhesion can both increase and decrease clonal cluster size depending on environmental conditions.
