    Genetic diversity and structure of the narrow endemic Seseli farrenyi (Apiaceae): implications for translocation by Núria Garcia-Jacas, Jèssica Requena, Sergi Massó, Roser Vilatersana, Cèsar Blanché, Jordi López-Pujol

    Published 2021-02-01
    “…Our main finding is that levels of genetic diversity in the natural populations of S. farrenyi are still high (He = 0.605), most likely as a result of a predominantly outcrossing mating system in combination with the limited time elapsed since the population decline. …”

    Sexual dimorphism in the methane seep-dwelling Costa Rican yeti crab Kiwa puravida (Decapoda: Anomura: Kiwaidae) by Juan Carlos Azofeifa-Solano, Olívia S. Pereira, Emily Jayne Cowell, Erik E. Cordes, Lisa A. Levin, Shana K. Goffredi, Jorge Cortés

    Published 2022-11-01
    “…These results suggest that claw weaponry is under sexual selection in K. puravida, which is probably related to the mating system of this deep-sea species. This is the first attempt to study the reproductive biology of K. puravida, and additional observations will be necessary to shed more light on this matter.…”
