Asymmetric and spiraled genitalia coevolve with unique lateralized mating behavior
Orbach, Dara N.; Brennan, Patricia L. R.; Hedrick, Brandon P.; Keener, William; Webber, Marc A.; Mesnick, Sarah L.
Scientific Reports (2020)
Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex remains largely…
Genetic homogeneity in the face of morphological heterogeneity in the harbor porpoise from the Black Sea and adjacent waters (Phocoena phocoena relicta)
Ben Chehida, Yacine; Thumloup, Julie; Vishnyakova, Karina; Gol’din, Pavel; Fontaine, Michael C.
Heredity (2019)
Absence of genetic differentiation is usually taken as an evidence of panmixia, but can also reflect other situations, including even nearly complete demographic independence among large-sized populations. Deciphering which situation…
Genital interactions during simulated copulation among marine mammals
Orbach, Dara N.; Kelly, Diane A.; Solano, Mauricio; Brennan, Patricia L. R.
Proceedings of the Royal Society B: Biological Sciences (2017)
Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer…
Unique feeding morphology in a new prognathous extinct porpoise from the Pliocene of California
Racicot, Rachel A.; Deméré, Thomas A.; Beatty, Brian L.; Boessenecker, Robert W.
Current Biology (2014)
Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods. Within both extinct and extant phocoenids, no evidence for…
