By depicting who eats whom, food webs offer descriptions of how groupings in nature
(typically species or populations) are linked to each other. For asking questions on how food …

Abstract (Adaptive) radiations have attracted evolutionary biologists for a long time as ideal
model systems to study patterns and processes of often rapid speciation. However, whereas …

Biogeography has traditionally focused on the spatial distribution and abundance of
species. Both are driven by the way species interact with one another, but only recently …

Although, in some insect taxa, wing shape is remarkably invariant, the wings of Anisopteran
dragonflies show considerable variation among genera. Because wing shape largely …

Oak galls are spectacular extended phenotypes of gallwasp genes in host oak tissues and
have evolved complex morphologies that serve, in part, to exclude parasitoid natural …

Biological communities are organized in complex interaction networks such as food webs,
which topology appears to be non‐random. Gradients, compartments, nested subsets and …

Coevolutionary studies on plants and plant‐feeding insects have significantly improved our
understanding of the role of niche shifts in the generation of new species. Evolving plant …

The study of reciprocal adaptation in interacting species has been an active and inspiring
area of evolutionary research for nearly 60 years. Perhaps owing to its great natural history …

Background Ecological speciation is a process in which a transiently resource-polymorphic
species divides into two specialized sister lineages as a result of divergent selection …

Aim Species geographical range sizes play a crucial role in determining species
vulnerability to extinction. Although several mechanisms affect range sizes, the number of …
