Nassella is an American genus which, according to its current circumscription, includes about 116 species, distributed from Canada to Argentina and Chile. It is characterized by its florets with the lemma conspicuously convolute, with an apical conspicuous or inconspicuous crown, and the palea shorter than the lemma; furthermore, the lemma presents...

The South American fur seal (SAFS) is distributed from Peru (Pacific Ocean) to Uruguay (Atlantic Ocean). However, there is a section of coastline of about 2,300 km along the Chilean coast where no SAFS are recorded. Based on morphological comparisons 3 geographic forms have been reported (Peruvian, South Chilean, Atlantic), whereas preliminary gene...
The Psyllobora picta species complex (Coleoptera: Coccinellidae: Coccinellini) was revised, with the description of two new species, Psyllobora lueri sp. nov. and Psyllobora pauline sp. nov., both from Chile. Psyllobora bicongregata was recorded for the first time from Brazil, and there is no confirmed record of this species for Chile. Also, P. pic...

Evolutionary biogeography aims to provide a hierarchical system of biotic regionalisation for areas of the
Earth that correspond to natural areas related by their common evolutionary history. In this context, the central Pampean Ranges of Argentina, formed by the mountain systems of Córdoba and San Luis, are immersed in the Chacoan dominion; however, higher-altitude environments of these mountains, namely highland grasslands and tabaquillo forests, have 5 relationships with the Andean region and other Neotropical areas that are different from the Chacoan dominion, which would indicate that the current classification would not be natural. To clarify their biogeographic relationships, a track analysis of the distribution of the biota of vertebrates and vascular plants of the highland grasslands and tabaquillo forests of central Pampean Argentinian Ranges was conducted. The obtained distributional patterns suggest that the area under study has diverse geobiotic origins, both Andean and Neotropical, indicating that, in this area, an interaction of biota with different evolutionary origins occurs; so, its status as a biogeographic province is proposed, belonging to the South American transition zone.
