Introduction
Doctor in Biology with an ecological perspective. I am particularly interested in how environmental characteristics at different spatial scales determine the composition and structure of communities in the environment over time.

Article
Full-text available
Events such as volcanic eruptions may act as disturbance agents modifying the landscape spatial diversity and increasing environmental instability. On June 4, 2011 the Puyehue-Cordon Caulle volcanic complex located on Chile (2236 m.a.s.l., 40° 02' 24? S- 70° 14' 26? W) experience a rift zone eruption ejecting during the first day 950 million metric...

Ecological communities are structured by combinations of factors known as habitat templates. These templates work as a filter allowing only species with particular traits or phenotypes to establish and persist excluding all others. Defining which habitat variables and spatial scales drive the assembly of freshwater communities is key to effective a...

La topografía y el uso de la tierra modulan la hidrología y la exportación de nutrientes en dos arroyos andino patagónicos.
Article
Fluvial dynamics are driven by multiple environmental factors and scales. Studies coupling hydrological and nutrient dynamics of mountain streams are almost non-existent in the Northern Patagonian region; which is characterised by a temperate-cold climate. We studied two adjacent streams with contrasting drainage basins: Casa de Piedra (41°07′30.11...

En Argentina, la expansión más reciente de uso agrícola se ha dado en los bosques secos del centro y norte del país. Como producto de la deforestación a gran escala y de los abruptos cambios en el uso de suelo, han surgido dinámicas ecológicas e hídricas que resultaban prácticamente desconocidas en estos paisajes. Dentro de estos nuevos ambientes,...
Article
Eutrophication is a key human-induced stressor in streams and often a consequence of intensified land use. We characterised how population density influences dissolved nutrients and its ratio in Patagonian Andean streams during the baseflow hydrological period. Research was conducted at stream Gutiérrez drainage basin (41°09′36.18′′S 71°24′37.19′′W...
Article
Habitat fragmentation and loss threaten freshwater biodiversity worldwide. Habitats that are essential as fish spawning and nursery sites are critical, and must be identified for conservation purposes. Littoral zones within Patagonian lakes, especially shallow vegetated areas, represent important areas for the Creole perch, Percichthys trucha. Spaw...

We characterized how land use influenced dissolved nutrients and periphytic algal biomass in an Andean basin from Northwest Patagonia. Nutrient export, especially dissolved inorganic nitrogen increased with human population density. However, no correlation between nutrient concentration and algal biomass was found, which could instead be limited by...
Article
Full-text available
Understanding how ecosystem processes influencing fish distribution operate across spatial scales is important to understand biological invasions. Salmonids, originally from the Northern Hemisphere, have been repeatedly introduced throughout the world, making them an ideal group to test hypotheses about factors driving invasions. We assessed the in...

In this research work, biology of Creole perch, Percichthys trucha, the largest top predator in the North Patagonia’s freshwater communities, in a deep oligotrophic lake in the region, focusing on (i) the differential use of littoral depth strata by age, (ii) age at maturity and spawning season and (iii) occurrence of reproductive migrations to veg...

Waterways act as integrators of ecosystems, their dynamics driven by multiple environmental factors and scales. To elucidate factors affecting hydrological and nutrient dynamics in Andean streams, we characterized two adjacent North Patagonian streams with contrasting drainage basins: Casa de Piedra (CP), originating in a small mountain lake and ru...
Article

La Patagonia Argentina conjuga en su extenso territorio diversos elementos naturales: montañas, mesetas, costas, desiertos, bosques, lagos y ríos. Dominada por pastos y arbustos bajos hacia el este, se transforma gradualmente hacia el oeste en un bosque denso hasta llegar a la cordillera de los Andes. La belleza colosal de sus paisajes ha sido ampl...
Article
According to assemblage theory, three factors regulate fish biogeography: restriction of dispersion, environmental restrictions and biotic interactions. The first two factors act on a regional scale and delimit the area of action of the third, which operates on a local scale. Salmonid introductions began in Patagonia in 1904, and this has led to a...
Article
Full-text available
Salmonid sport fishery management in Argentinian Patagonia is usually guided by stakeholder perceptions, which do not consider the biological and ecological constraints acting upon aquatic resources. An example of this are management policies for Traful Lake, where Atlantic salmon, Salmo salar L., was actively stocked during the last decade in an a...

El 4 de junio de 2011 entró en erupción el Complejo Volcánico Puyehue – Cordón Caulle, del lado Oeste de la cordillera de los Andes (40º 32' Latitud Sur y 72º 7' Longitud Oeste), eyectando 950 millones de toneladas de ceniza hacia la atmósfera. Debido a la predominancia de vientos del cuadrante Oeste, 24 millones de hectáreas de la Patagonia Argent...

Volcanic eruptions are natural phenomena with the most diverse and varied consequences, and have important effects on both terrestrial and aquatic environments. On June 4 th , 2011 the volcanic Puyehue Cordón-Caulle complex (2.236 masl, 40º 32-72º 2, Chile) erupted explosively ejecting on the first day, 950 million metric tons of ashes into the atm...

La comunidad rural Ñirihuau (Dina Huapi, RN) se ubica en la margen derecha del río Ñirihuau, en un paisaje ecotonal de estepa-bosque y tiene potencial para actividades recreativas y turísticas. Está conformada por unas cuarenta familias que desarrollan actividades productivas de subsistencia. Se propuso incrementar la relación de la comunidad con l...

Recorrer el entorno natural es una práctica saludable que permite descubrir e interpretar el paisaje, establecer contacto con la naturaleza y conocer la historia zonal. Con el objetivo de conocer y valorar los recursos naturales de la comunidad Ñirihuau (Dina Huapi, RN), y a pedido de la Asociación Civil, se planteó el desarrollo de un sendero de i...

Fires are the most devastating anthropogenic disturbances in forests of the A ndean-Patagonian region. They severely affect surface soil physical and chemical characteristics, as well as vegetation and fauna, thus inc reasing the risk of erosion. These forests are very import ant for the conservation of biodiversity, climate and watershed regulatio...

Project
La Patagonia Sumergida es un proyecto de divulgación que tiene por objetivo poner en valor los recursos acuáticos del Parque Nacional Nahuel Huapi, Patagonia Argentina. A través de la fotografía subacuática y textos interpretativos se muestran los paisajes sumergidos de la Patagonia y el valor ecosistémico de los mismos. Proyecto declarado de interés para el Parque Nacional Nahuel Huapi. La Patagonia Sumergida (Patagonia Underwater) is an outreach project whose objective is to set the value on the underwater resources of the Nahuel Huapi National Park, Patagonia, Argentina. Through underwater photography and interpretive texts, we show the submerged landscapes of Patagonia and their ecosystemic value. A declared project of interest for the Nahuel Huapi National Park.
