Latitudinal and elevational gradients provide valuable experimental settings for studies of
the potential impact of global warming on forest tree species. The availability of long‐term …

Species introductions promote secondary contacts between taxa with long histories of
allopatric divergence. Anthropogenic contact zones thus offer valuable contrasts to …

Transmissible cancers, in which cancer cells themselves act as an infectious agent, have
been identified in Tasmanian devils, dogs, and four bivalves. We investigated a …

Understanding population divergence that eventually leads to speciation is essential for
evolutionary biology. High species diversity in the sea was regarded as a paradox when …

Introduced species can impose profound impacts on the evolution of receiving communities
with which they interact. If native and introduced taxa remain reproductively semi‐isolated …

Human‐mediated transport creates secondary contacts between genetically differentiated
lineages, bringing new opportunities for gene exchange. When similar introductions occur in …

The Mytilus complex of marine mussel species forms a mosaic of hybrid zones, found across
temperate regions of the globe. This allows us to study 'replicated'instances of secondary …

Rafting has been proposed as an effective mechanism for species without free-living pelagic
larvae to achieve long-distance dispersal, theoretically preventing population differentiation …

This thesis explores the genetic variation and evolution of mosquito populations within the
Anopheles gambiae complex (AGC), a closely related group of mosquito species serving as …

When the ranges of closely-related lineages are large, and overlap**, we can often study
introgression at many “replicated” contacts, with different locations and spatial scales. Here …
