Range Extension of the Popeye Catalufa (Pristigenys serrula, Gilbert 1891) to Central Chile During the "El Niño" Southern Oscillation (ENSO) 2023-2024. [PDF]

open access: yesEcol Evol
Phylogenetic and morphological analyses confirm P. serrula in central Chile (32° S). The geographical distribution of P. serrula in central Chile extends 9° southward. This extension is associated with the “El Niño” Southern Oscillation (ENSO). ABSTRACT We report the presence of Pristigenys serrula Gilbert 1891 off Zapallar (−32.568253, −71.464225 ...

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs. [PDF]

open access: yesIntegr Zool
Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but

The role of biogeographical barriers on the historical dynamics of passerine birds with a circum-Amazonian distribution. [PDF]

open access: yesEcol Evol
This study found similarities at populational, phylogenetic, and evolutionary levels among four taxonomic groups of passerine birds with a circum‐Amazonian distribution. The presence of Refugia result of climatic oscillations during the Pleistocene was the main drive in the diversification of these circum‐Amazonian taxa.
