Since the first investigation 25 years ago, the application of genetic tools to address
ecological and evolutionary questions in elasmobranch studies has greatly expanded. Major …

Sequence capture and restriction site associated DNA sequencing (RAD-Seq) are two
genomic enrichment strategies for applying next-generation sequencing technologies to …

Darwin's finches, inhabiting the Galápagos archipelago and Cocos Island, constitute an
iconic model for studies of speciation and adaptive evolution. Here we report the results of …

Speciation generally involves a three-step process—range expansion, range fragmentation
and the development of reproductive isolation between spatially separated populations …

Many hypotheses have been proposed to explain high species diversity in Amazonia, but
few generalizations have emerged. In part, this has arisen from the scarcity of rigorous tests …

Evolutionary theory has gained tremendous insight from studies of adaptive radiations. High
rates of speciation, morphological divergence, and hybridization, combined with low …

The Amazon is the primary source of Neotropical diversity and a nexus for discussions on
processes that drive biotic diversification. Biogeographers have focused on the roles of …

Colonization, speciation and extinction are dynamic processes that influence global patterns
of species richness,,,,–. Island biogeography theory predicts that the contribution of these …

Comparative genetic studies of non-model organisms are transforming rapidly due to major
advances in sequencing technology. A limiting factor in these studies has been the …

RNA interference (RNAi) is a technique used for transgene-mediated gene silencing based
on the mechanism of posttranscriptional gene silencing (PTGS). PTGS is an ubiquitous …
