3. Evolution of the Biodiversity Hotspot of Madagascar from the Eye of Diving Beetles : Phylogeny, colonization and speciation
Sammanfattning : Dytiscidae, contains numerous endemic and non-endemic species on Madagascar. Their evolutionary history is largely unknown on the island. Herein, I use analyses to infer phylogenetic relationship among groups of diving beetles, with a focus on the subfamily Dytiscinae and endemic species in two other groups of Dytiscidae. LÄS MER

Co-evolved patterns of these traits are known as life history strategies (LHS) and variation occurs between individuals, populations, and species. LÄS MER
