Taxon cycles in Neotropical mangroves

Plants, 2022
Abstract The concept of taxon cycle involves successive range expansions and contractions over time through which a species can indefinitely maintain its core distribution. Otherwise, it becomes extinct. Taxon cycles have been defined mostly for tropical island faunas, examples from continental areas are scarce and ...

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Comparative analysis of cytoarchitectonic and neurochemical aspects of the globus pallidus in the rock cavy (Kerodon rupestris) and the common marmoset (Callithrix jacchus)

The Anatomical Record, EarlyView.
Abstract The globus pallidus (GP), a subcortical structure within the basal ganglia, plays a crucial role in modulating cortico‐subcortical circuits related to motor control and associative/limbic functions. However, the cytoarchitectonic and neurochemical organization of this structure remains poorly characterized in naturally existing wild‐type ...
