Phage therapy, long overshadowed by chemical antibiotics, is garnering renewed interest in
Western medicine. This stems from the rise in frequency of multi-drug-resistant bacterial …

Phenotypic plasticity (the ability of a single genotype to produce multiple phenotypes in
response to variation in the environment) is commonplace. Yet its evolutionary significance …

Parasites and infectious diseases are everywhere and represent some of the most potent
forces shaping the natural world. They affect almost every aspect imaginable in the life of …

Studying the coevolutionary dynamics between bacteria and the bacteriophage viruses that
infect them is critical to understanding both microbial diversity and ecosystem functioning …

Emerging viral diseases are often the product of a host shift, where a pathogen jumps from
its original host into a novel species. Phylogenetic studies show that host shifts are a …

The processes responsible for the evolution of key innovations, whereby lineages acquire
qualitatively new functions that expand their ecological opportunities, remain poorly …

Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

Emerging diseases represent a growing worldwide problem accompanying global
environmental changes. There is tremendous interest in identifying the factors controlling the …

Environmental heterogeneity is considered a general explanation for phenotypic
diversification, particularly when heterogeneity causes populations to diverge via local …

Ecological, evolutionary and molecular models of interactions between plant hosts and
microbial pathogens are largely based around a concept of tightly coupled interactions …
