Many species are expanding their range polewards, and this has been associated with rapid
phenotypic change. Yet, it is unclear to what extent this reflects rapid genetic adaptation or …

Background Evolutionary processes can cause strong spatial genetic signatures, such as
local loss of genetic diversity, or conflicting histories from mitochondrial versus nuclear …

Ischnura senegalensis Rambur, 1842 is among the most widespread damselfly species in
the world. Unlike dragonflies with strong migration abilities, I. senegalensis have limited …

Geographic range size is a key ecological and evolutionary characteristic of a species, yet
the causal basis of variation in range size among species remains largely unresolved. One …

Conservation efforts are leading to demographic growth and spatial expansion of some
previously endangered species. However, past population bottlenecks or population size …

North African odonates are facing conservation challenges, not only by increased
degradation and loss of habitat, but also by having poorly understood taxonomy …

While phylogeographic data provide valuable information to inform conservation plans,
there are comparatively few Odonata phylogeographic studies. This lack of research is …
