Introduction
I am an evolutionary biologist interested in biogeography, evolutionary history and ecology of high latitudes organisms, in particular freshwater and marine invertebrates. I have a PhD focused on understanding the macro and micro-evolutionary processes that underlie the current distribution of freshwater biota in Antarctic and sub-Antarctic regions. I am also working in the release of biodiversity occurrence information through digital platforms.

Aim We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate (1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or long-term diversification; and (2) the age and origin of sub-Antarctic and Antarctic Boeckella species, with particu...

Two species of scallop, Austrochlamys natans (“ Ostión del Sur ”) and Zygochlamys patagonica (“ Ostión patagonico ”) are presently exploited in the southern part of the Magallanes Province (MP). The lack of clarity in taxonomic identification and ecological aspects is generating both erroneous extraction statistics and an unperceived harvesting pre...

Members of the trochoidean genus Margarella (Calliostomatidae) are broadly distributed across Antarctic and sub-Antarctic ecosystems. Here we used novel mitochondrial and nuclear gene sequences to clarify species boundaries and phylogenetic relationships among seven nominal species distributed on either side of the Antarctic Polar Front (APF). Mole...

El cambio climático global afecta a todas las regiones del planeta, pero hay zonas geográficas que son especialmente vulnerables en el corto plazo. Entre estas regiones, Magallanes sobresale, especialmente la ecorregión subantártica de Magallanes (47° S-56° S) 1. Esta ecorregión presenta singularidades ecosistémicas y ecológicas tales como sus gran...

Environmental conditions were particularly severe during the Last Glacial Maximum, altering the distribution of the Southern Hemisphere biota, particularly at higher latitudes. The copepod Boeckella poppei is the only macroscopic continental invertebrate species known to be distributed today across the three main biogeographic regions in Antarctica...

Chapter
Antarctic terrestrial ecosystems contribute a tiny proportion of the area of the continent and host an impoverished and often cryptic biota. In recent years it has been realized that much of this biota is unique to the continent, carrying signals of its evolutionary radiation on multi-million-year timescales, some even pre-dating the final breakup...

Copepods are present in numerous aquatic environments, playing key roles in food webs, and are thought to be useful indicators of environmental change. Boeckella is a calanoid copepod genus distributed mainly in the Southern Hemisphere, with 14 species reported at higher southern latitudes in South America and Antarctica. We present an updated data...

Antarctic and Subantarctic lakes are unique ecosystems with relatively simple food webs, which are likely to be strongly affected by climate warming. While Antarctic freshwater invertebrates are adapted to extreme environmental conditions, little is known about the factors determining their current distribution and to what extent this is explained...

La separación de la fauna antártica y subantártica es profunda, antigua y afectó a la mayoría de los organismos acuáticos. Existe un aislamiento de varios millones de años entre poblaciones de especies de algas e invertebrados marinos codistribuidas en ambos lados del paso Drake. Sin embargo, aún existen vestigios de esa antigua conexión. En los úl...

The Quaternary brought numerous cycles of ice sheet extension and contraction across the Antarctic continent, resulting in major disruption of terrestrial habitats and the extinction of diverse taxa. Currently there are two main hypotheses to explain the present-day occurrence of freshwater biota in Antarctica: 1) recent colonization from lower lat...

One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some marine benthic species to move, adapt or go extinct. The marine benthic species inhabiting the Antarctic upper continental shelf...

Broadcasting is the predominant spawning behavior among benthic marine invertebrates, mainly associated with planktotrophic and planktonic lecitotrophic development. Broadcasting allows genetic mixing that should contribute to increase the genetic diversity of a female clutch. Conversely, in brooding species characterized by protected development,...

The purpose of PROTEKER** is to create a coastal ecological and genetic observatory. In the current context of climate changes, variations of sea level and marine biodiversity (extinction, shifts, replacements, invading species) will concern the Southern Islands, especially the coastal benthic communities. Kerguelen Islands, situated at the norther...

Accurate species identification remains a basic first step in any study of biodiversity, particularly for global changes and their consequences. Thus, there is a pressing need for taxonomic expertise in a broad range of taxa. DNA barcoding has proved to be a powerful alternative method to traditional morphological approaches, allowing to complement...
