Studies in diverse biological systems have indicated that host–parasite co-evolution is
responsible for the extraordinary genetic diversity seen in some genomic regions, such as …

During meiosis, both alleles of any given gene should have equal chances of being
inherited by the progeny. There are a number of reasons why, however, this is not the case …

Host individuals are often coinfected with diverse parasite assemblages, resulting in
complex interactions among parasites within hosts. Within hosts, priority effects occur when …

In spite of the growing interest in the role of the gut microbiome (GM) in host physiology and
health, the mechanisms governing its assembly and its effects on the environment are poorly …

Biological diversity abounds in potential study topics. Studies of model systems have their
advantages, but reliance on a few well-understood cases may create false impressions of …

Social interactions with conspecifics are key to the fitness of most animals and, through the
transmission opportunities they provide, are also key to the fitness of their parasites. As a …

Sudden oak death caused by Phytophthora ramorum has been actively managed in Oregon
since the early 2000s. To date, this epidemic has been driven mostly by the NA1 clonal …

Study of the congruence of population genetic structure between hosts and pathogens gives
important insights into their shared phylogeographical and coevolutionary histories. We …

Hybridization is one of the major factors contributing to the emergence of highly successful
parasites. Hybrid vigour can play an important role in this process, but subsequent rounds of …

Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With
climate change, these pathogens are expected to emerge more frequently. Evolution can …
