Consumer co-evolution as an important component of the eco-evolutionary feedback

The role of predator evolution in eco-evolutionary dynamics has received less attention than that of prey. Here, Hiltunen and Becks show that prey anti-predator traits evolve faster and are more variable in the presence of co-evolved predators, resulting in altered community dynamics.

Pre-exposure of abundant species to disturbance improves resilience in microbial metacommunities

Community resilience to stress is affected by factors such as pre-exposure to the same stress and intercommunity dispersal. The authors show that pre-exposing the most dominant members of a 23-species bacterial community to different levels of antibiotic stress leads to rapid evolution of resistance that improves metacommunity resilience even under high levels of dispersal.

Dual-stressor selection alters eco-evolutionary dynamics in experimental communities

Pseudomonas fluorescens is subjected to two stressors: the predatory thermophile Tetrahymena and sublethal antibiotic treatment. The interaction slows adaptation and destabilizes ecological dynamics.

Repeatable ecological dynamics govern the response of experimental communities to antibiotic pulse perturbation

By exposing an experimental 34-species bacterial community to different levels of pulse antibiotic disturbance with or without immigration, the authors identify a highly repeatable community response, the magnitude of which increases with increasing antibiotic levels.

Dynamical trade-offs arise from antagonistic coevolution and decrease intraspecific diversity

How a trait evolves depends on the shape of its fitness trade-off. Here, Huang et al. demonstrate evolution of trade-off shape in an experimental predator-prey system and develop a mathematical model of trait evolution when the underlying trade-off can also evolve.

Ecology determines how low antibiotic concentration impacts community composition and horizontal transfer of resistance genes

Johannes Cairns et al. show that spatial structure and predation shape the ways in which a low concentration of antibiotics alters the composition and diversity of bacterial community. This study suggests that ecological factors influence how antibiotic resistance spreads.
