Some forms of positive density-dependence can favor species coexistence even if competitive species benefit the most from positive density-dependence.

Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

By integrating theoretical and empirical approaches, the results show that linking abiotic factor and biotic interactions on the niche width will be critical for understanding species-specific responses to climate change.

By modelling organisms that alternate between individual and colonial lifestyles, the well-known Parrondo's paradox can emerge in an ecological setting without the need for stochastic environmental variation.

Open questions of cancer adaptive therapy are discussed through the lens of mathematical modeling, categorized into three sections, (1) integrating appropriate components into mathematical models, (2) dosing protocol design and validation, and (3) challenges and opportunities in clinical translation.

Tumoral group phenotypic compositions and their relationships with the fitness of individual malignant cells in different ecological contexts represent crucial, previously unexplored dynamics in tumor progression.

A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.

The growth of wild Drosophila larvae on fruits is promoted by a yeast releasing essential nutrients extracellularly or by a stable association with a nutrient-providing bacterium established by microbe–microbe interactions.
