Herbarium collection of the Pontificia Universidad Católica de Valparaíso (PUCV), Chile.

Background: This database gathers 10,721 specimens, belonging to 2,578 species from the Chilean vascular flora (angiosperms, gymnosperms and pteridophytes) deposited in the Herbarium of the Pontificia Universidad Católica de Valparaíso (PUCV) in Chile. The PUCV botanical collection was started by the renowned botanist Otto Zöllner and represents a major natural historical legacy for central Chile, with decades of information represented through preserved specimens. This collection is currently deposited in the Curauma campus of the PUCV.

Ecological Impacts of Exotic Species on Native Seed Dispersal Systems: A Systematic Review.

Exotic species are one of the main threats to biodiversity, leading to alterations in the structure and functioning of natural ecosystems. However, they can sometimes also provide ecological services, such as seed dispersal. Therefore, we assessed the ecological impacts of exotic species on native dispersal systems and the mechanisms underlying the disruption of mutualistic plant-disperser interactions.

Rizoma: a new comprehensive database on traditional uses of Chilean native plants.

Background: We describe Rizoma, a new comprehensive online database on traditional uses of Chilean flora. The Rizoma database was built by reviewing multiple data sources on the uses of native plants and integrating phytogeographic and ecological aspects of plant species. This database attempts to safeguard traditional knowledge by making it available and visible to society, providing 1380 use records from 736 vascular plant species native to Chile.

Revealing the Characteristics of the Antarctic Snow Alga gen. et sp. nov. Through Taxonomy, Physiology, and Transcriptomics.

Snow algae play crucial roles in cold ecosystems, however, many aspects related to their biology, adaptations and especially their diversity are not well known. To improve the identification of snow algae from colored snow, in the present study we used a polyphasic approach to describe a new Antarctic genus, with the species type . This new taxon was isolated of colored snow collected from the Collins Glacier (King George Island) in the Maritime Antarctic region.

Phylogeographic structure in benthic marine invertebrates of the southeast Pacific coast of Chile with differing dispersal potential.

The role of dispersal potential on phylogeographic structure, evidenced by the degree of genetic structure and the presence of coincident genetic and biogeographic breaks, was evaluated in a macrogeographic comparative approach along the north-central coast of Chile, across the biogeographic transition zone at 30°S. Using 2,217 partial sequences of the mitochondrial Cytochrome Oxidase I gene of eight benthic invertebrate species along ca. 2,600 km of coast, we contrasted dispersal potential with genetic structure and determined the concordance between genetic divergence between biogeographic regions and the biogeographic transition zone at 30°S.
