Integrative and Comparative Biology, Vol. 59, No. 4 (October 2019), pp. 900-911 (12 pages) Mitochondria have been known to be involved in speciation through the generation of Dobzhansky–Muller ...

Corrales, a recent biological sciences Ph.D. graduate from the University of Rhode Island, and his advisor, Associate ...

The process by which species evolve can be illuminated by investigating barriers that limit gene flow between taxa. Recent radiations, such as Heliconius butterflies, offer the opportunity to compare ...

What is ecological speciation? -- Predictions and tests of ecological speciation -- A source of divergent selection -- A form of reproductive isolation -- A genetic mechanism to link selection to ...

Researchers from the University of Tsukuba and Ryutsu Keizai University find that patterns of reproductive isolation in a haplodiploid spider mite support the prevailing view of the evolution of ...

New research on horseshoe bats published in Nature provides a fascinating example of how a central barrier to speciation - the evolution of reproductive isolation - can be overcome, without any need ...

Female giant water bugs lay their eggs on a male's back after mating and the male takes care of the eggs until the nymphs are hatched, a couple of weeks later. A study led by Dr. Tomoya Suzuki of ...

Hendry's team observed that male river sockeyes are slimmer than their lake counterparts (to better deal with the river's strong current), while the female river sockeye are larger than their beach ...

This process, called "reinforcement", prevents closely related species from interbreeding thus driving them further apart genetically and promoting speciation. Although scientists have speculated ...
