Myriad branches in the tree of life are intertwined through ecological relationships. Biologists
have long hypothesized that intimate symbioses between lineages can influence …

Range expansion results from complex eco‐evolutionary processes where range dynamics
and niche shifts interact in a novel physical space and/or environment, with scale playing a …

Introduction The seed-associated microbiome has a strong influence on plant ecology,
fitness, and productivity. Plant microbiota could be exploited for a more responsible crop …

Parasites and other symbionts are crucial components of ecosystems, regulating host
populations and supporting food webs. However, most symbiont systems, especially those …

Parasite diversification is influenced by many of the same factors that affect speciation of free-
living organisms, such as biogeographic barriers. However, the ecology and evolution of the …

A fundamental aspect of symbiotic relationships is host specificity, ranging from extreme
specialists associated with only a single host species to generalists associated with many …

The resiliency of populations and species to environmental change is dependent on the
maintenance of genetic diversity, and as such, quantifying diversity is central to combating …

Aim Highly host‐specific symbionts are very rarely found except with their typical host
species. Although switches to new hosts are rare and difficult to detect, a switch to a host …

Host–symbiont relationships are ubiquitous in nature, yet evolutionary and ecological
processes that shape these intricate associations are often poorly understood. All orders of …

Speciation via host-switching is a macroevolutionary process that emerges from a
microevolutionary dynamic where individual parasites switch hosts, establish a new …
