Locus diagnóstico para identificação de hí­­bridos de peixe-rei (odontesthes humensis and odontesthes bonariensis) em população natural [PDF]

Boletim do Instituto de Pesca, 2022
  A hibridação é um fenômeno natural que ocorre mais frequentemente em peixes do que em outros vertebrados. Para detectá-la, são utilizados marcadores moleculares nucleares e mitocondriais, os quais fornecem resultados valiosos.

Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid <i>Odontesthes regia</i>. [PDF]

Ecol Evol
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...

Foraging Observations: Novel Trophic Interactions Between the Andean Gull (<i>Chroicocephalus serrranus</i>) and Endangered Vertebrates of Lake Titicaca. [PDF]

Ecol Evol
We show that the Andean gull predates on both the Titicaca Grebe and the Titicaca Giant Frog. Both these species are critically endangered, and it was unknown that they had natural predators before this. ABSTRACT We record two new predation events and one new kleptoparasitic Andean Gull (Chroicocephalus serranus) behavior, interactions that directly ...
