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 ...

The arrival of Barn Swallows (Hirundo rustica) to a neotropical city is related to precipitation in wintering areas [PDF]
, 2010 We studied the relationship between two macro-scale environmental factors (i.e., rainfall, temperature) and the arrival of Barn Swallows (Hirundo rustica) to a Mexican Neotropical city in the past 13 years (1997?2009).

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.

Nomenclatural and systematic changes in the Neotropical caddisflies (Insecta: Trichoptera) [PDF]
, 1999 Recent work on a catalog of the Neotropical caddisflies has resulted in the recognition of the need to make numerous lectotype designations, new names for homonyms, specific and generic synonymies, transfers of species between genera and genera between ...

BREEDING BIOLOGY OF PASSERINES IN THE SUBTROPICAL BRAZILIAN ATLANTIC FOREST [PDF]
, 2016 Information on breeding biology of birds is fundamental for the understanding of life history evolution and conservation. This information is only beginning to accumulate for Neotropical birds but the southern subtropics are still overlooked.

Bite force estimates and morphological correlations of jaw muscles in parrots
The Anatomical Record, EarlyView.Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

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 ...
