We test whether body size or habitat preference is associated with the formation of geographic isolation in thePachydactylusgroup in a phylogenetic context. We have generated a comprehensive time-calibrated multi-locus phylogeny of the group, and obtained body size and habitat preference trait data f...

All individual pikas included in this study were live-trapped and released at point of capture after processing. No animals were euthanized for this study. The majority of tissue samples were collected over the last ten years as part of long-term monitoring efforts or recent live-trapping studies...
Thus, the logical extension have missed some proportion of these communities, of this is that if different regions harbour different because this would have been a systematic bias (the communities and populations, as we have shown, same isolation procedure was used throughout), the that these ...
As such, one might expect animals living in forest shade to show shifts to shorter wavelengths in their visual pigment sensitivity in response to the ambient light, and this is the shift we observe in the LWS and MWS cones, and the rods of P. e. elegans when compared to P. e. flav...
a range of paternally and bi-paren- tally inherited markers, in addition to maternally inherited marker, are clearly necessary to complete the understanding of possible proximate and ultimate factors that determine and influence the dispersal of males and females in these rather cryptic animals. Especi...
Geographic isolation c. Long periods of time d. Genetic isolati Comment on the evolution of animals and population of humans. What are the causes of clumped population distribution? What is fitness and what role does it play in population genetics and evolution? Describe the geogra...
Genome duplication, or polyploidization, is common in plants, and has been shown to result in rapid reproductive isolation [30, 72–75]. In diatoms, few studies have examined changes in DNA content. Genome size differences of two-fold have been observed among ITS1 lineages of the diatom D....
Information obtained from the analysis of dust, particularly biological particles such as pollen, plant parts, and fungal spores, has great utility in forensic geolocation. As an alternative to manual microscopic analysis of dust components, we developed
This pattern holds for many groups of plants and animals. Their well-defined boundaries and their isolation make islands a relevant context to describe and interpret spatial patterns of evolution, particularly speciation. Indeed, the literature contains numerous cases of species formation on distinct ...
