Environmental and zooplankton parameter changes during the drying of a saline shallow temporary lake in central Argentina

open access: yesUniversitas Scientiarum, 2017
Central Argentina has numerous saline lakes sustained by groundwater sources and rainfall. These lakes are temporary and experience significant changes in water level and salinity, depending on wet and dry climate cycles.

Tracing the biogeographic history of the world's most isolated insular floras

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 4, Page 952-973, July 2025.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.

Zooplankton diversity of a protected and vulnerable wetland system in southern South America (Llancanelo area, Argentina)

open access: yesInternational Aquatic Research, 2016
In arid regions, climatic conditions exert a great control on the aquatic systems present, but recent changes in climate have produced an enhanced salinization of the aquatic environments located there.

Distribution of Boeckella poppei (Mrázek, 1901) (Copepoda: Calanoida) on the Livingston Island, Maritime Antarctic

open access: yesActa zoologica bulgarica, 2023
The available data on the localities (including new localities) of the calanoid copepod Boeckella poppei on the Livingston Island, Maritime Antarctic, are summarised. The results suggest a substantial expansion in the distribution of the species, likely owing to recent climate change and the resulting freeing from permanent ice or snow of additional ...

An update of the distribution of Boeckella gracilis (Daday, 1902) (Crustacea, Copepoda) in the Araucania region (38°S), Chile, and a null model for understanding its species associations in its habitat Actualización de la distribución de Boeckella gracilis (Daday, 1902) (Crustacea, Copepoda) en la región de la Araucanía (38°S), Chile, y un modelo nulo para comprender sus asociaciones específicas en su habitat

open access: yesLatin American Journal of Aquatic Research, 2010
The crustacean zooplankton of Chilean inland waters are characterized by abundant calanoid copepods, mainly from the gemís Boeckella. The present study aims to update the distribution of Boeckella gracilis in the inland waters of the Araucania region (38-
