Climate change and evolutionary adaptations at species' range margins.
During recent climate warming, many insect species have shifted their ranges to higher latitudes and altitudes. These expansions mirror those that occurred after the Last Glacial Maximum when species expanded from their ice age refugia. Postglacial range expansions have resulted in clines in genetic diversity across present-day distributions, with a reduction in genetic diversity observed in a ...
متن کاملButterfly genome reveals promiscuous exchange of mimicry adaptations among species
The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferring beneficial traits between species.Hereweuse genomic tools to investigate introgression inHeliconius, a rapidly radiating genus of neotropical butterflieswidely used in studies of ecology, behaviour,mimicry ...

متن کاملPhylogenetic relationships and climatic adaptations in the Drosophila takahashii and montium species subgroups.
We analyze phylogenetic relationships among temperate, subtropical highland, and subtropical lowland species of the Drosophila takahashii and montium species subgroups based on sequence data of COI and Gpdh genes and discuss the evolution of temperate species in these subgroups with reference to their climatic adaptations. In the takahashii subgroup, D. lutescens (the temperate species) branche...
متن کاملHominid Adaptations and Extinctions
According to David W. Cameron, the goal of his book Hominid Adaptations and Extinctions is “to examine the evolution of ape morphological form in association with adaptive strategies and to understand what were the environmental problems facing Miocene ape groups and how these problems influenced ape adaptive strategies” (p. 4). Cameron describes himself as being “acknowledged internationally a...
