A new species of Peckoltia (Siluriformes, Loricariidae) from the rapids of the Rio Tocantins‐Araguaia basin, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Here, we describe a new species of Peckoltia (Loricariidae; Hypostominae) from the rapids of the Rio Tocantins‐Araguaia basin, previously identified as Peckoltia vittata, using an integrative taxonomy approach. The new species is distinguished from congeners by ventral region presenting diffuse stripes on surface, not presenting spots or ...

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

open access: yesJournal of Systematics and Evolution, EarlyView.
This study investigated the systematics and biogeography of the Middle American clade of Neotropical catfishes of the genus Rhamdia using mitogenome‐wide comparative data. Results refine and corroborate previous phylogenetic hypotheses, including the deep paraphyly of the species Rhamdia laticauda; they support a scenario of northward dispersal from ...
