Molecular phylogeny and biogeography of the temperate Gondwanan family Triaenonychidae (Opiliones: Laniatores) reveals pre-Gondwanan regionalization, common vicariance, and rare dispersal
(Csiro Publishing, 2020-08)
Triaenonychidae Sørensen in L. Koch, 1886 is a large family of Opiliones with ∼480 described species broadly distributed across temperate forests in the Southern Hemisphere. However, it remains poorly understood taxonomically, ...
A Morphometric Analysis of Serpocaulon gilliesii (Polypodiaceae) Reveals a New Species for Yungas Montane Forest, S. Australe
(American Society of Plant Taxonomists, 2019-01)
A new species, Serpocaulon australe, from the Yungas Montane Forest of Argentina and Bolivia, is described based on a reinterpretation of the name S. gilliesii. The new species is similar to S. lasiopus, but can be ...

(American Society of Plant Taxonomists, 2020-05-13)
Gomphrena meyeniana is an extremely variable species from the Andean highlands, which has attracted the attention of many botanists because it is the world’s highest-elevation C4 eudicot and because of its wide morphological ...
Fluctuating asymmetry as a tool for assessing development stability on small mammals from the Argentine agroecosystem
(Systematics, Biogeography, and Evolution meeting 2021's organizing committe, 2021)
Evolutionary biologists have not paid as extensive attention to nongenetic compo-nents of variation as they have done to genetic variation of phenotypic traits. Gen-erally, nongenetic components are grouped in categories ...
