Sperm maturation and capacitation in the open thelycum shrimp Litopenaeus (Crustacea: Decapoda: Penaeoidea)

TL;DR: It is demonstrated for the first time that reactivity is significantly superior in sperm cells that have been attached to the open thelycum for some hours, as compared to sperm in males (prior to transfer), which suggests that matured sperm cells of L. occidentalis become capacitated to react against egg water after mating.
Journal ArticleDOI

Induction of sperm activation in open and closed thelycum penaeoid shrimps

TL;DR: The modified technique induced activation of sperm removed from females' seminal receptacles, and demonstrated that sperm from males of T byrdi and X riveti do not react against conspecific EW, indicating that further maturation is required in seminal receptacle.
Journal ArticleDOI

Una nueva especie de Euglena (Euglenozoa: Euglenales) aislada de ambientes extremófilos en las Pailas de Barro del Volcán Rincón de la Vieja, Costa Rica

TL;DR: Molecular phylogeny studies using 18S rDNA and Gap C genes indicated that the new species of euglena isolated from a hot and acid mud pool located in Las Pailas de Barro, Volcan Rincon de la Vieja, Costa Rica is related to E mutabilis.
Journal Article

[A new species of Euglena (Euglenozoa: Euglenales) isolated from extreme environments in "boiling mudflats" of Rincón de la Vieja volcano, Costa Rica].

TL;DR: A new species of euglena isolated from a hot and acid mud pool located in Las Pailas de Barro, Volcán Rincón de la Vieja, Costa Rica is described and its taxonomic characters are discussed and compared with other closely related species of the genus.
