Pleistocene mafic volcanoes in the Puna–Cordillera Oriental boundary, NW-Argentina

Journal of Volcanology and Geothermal Research, 2006
Abstract Los Gemelos and El Saladillo are both monogenetic, strombolian, basaltic–shoshonitic volcanoes that constitute the easternmost recognized examples of mafic Plio-Quaternary volcanism in the southern Central Andes. Two regional faults delimit the borders of the Calchaqui valley, as thrusts with opposite vergence: the eastern Calchaqui fault ...

Biotic Assembly of the Species of Triatomini (Hemiptera: Reduviidae: Triatominae) in the Mexican and South American Transition Zones

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim To infer the biogeographic history of the Triatomini by evaluating how their species became part of the biogeographic transition zones of the New World. This group of blood‐feeding insects includes key vectors of Chagas disease. Understanding their dispersal and diversification over geological time may help elucidate the temporal dynamics ...

So Young, So Rich: Habitat Shifts Combined With Trait Evolution Promoted Species Radiation in Senecio in the Andes

Journal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim The outstanding Andean biodiversity has been linked to the occurrence of evolutionary radiations that are common among high‐elevation plant lineages. One of the most iconic examples is found in the species‐rich genus Senecio, with an impressive variation in growth forms and habitat preference.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.
