Introduction
Over the years, my research experiences mainly focused on two top-predator species, wolf and mountain lion, comprehending aspects of their food habits, spatial ecology, population genetics and landscape connectivity. Particular interest has been given to anthropogenic ecological disturbances and human activities impact on population persistence. Among methods and techniques used: VHF and GPS monitoring, camera trapping, scats analysis, microsatellites genotyping and molecular analyses.

The puma (Puma concolor Linnaeus, 1771) is the top predator with the widest distribution in America. Since the establishment of European settlers on the American continent, puma populations have experienced significant contractions and reductions in their original distribution. In Argentina, the management of the conflict between humans and pumas (...
Understanding both native and non-native species ecology, including their distribution and interaction, is crucial for making informed decisions on conservation and management strategies,
particularly for endemic threatened species. In this study, we report an update on the non-native Finlayson’s squirrel Callosciurus finlaysonii invasion of southe...
ContextIdentification of areas with high connectivity is crucial for large carnivores’ management and conservation, especially where landscape has been modified by human activities. Partially under legal hunting control, south-central Argentine pumas (Puma concolor) have been described to be structured into two distinct groups with an inverse corre...
Habitat fragmentation and the associated landscape connectivity loss can reduce gene flow among populations, which could lead to a decrease in genetic variability, and an increase in the extinction risk of a species. The main goal of this study was to provide genetic diversity and population structure data for Pampas foxes from the southern Argenti...
Understanding population structure and spatial distribution of genetic diversity is an important aspect of developing appropriate management plans for wildlife conservation, especially for large carnivores like the puma (Puma concolor). Human persecution and habitat degradation represent the main threats to the species’ conservation in Argentina, w...
Understanding the food habits of mammalian carnivores is crucial for the comprehension of the role of apex-predators in maintaining healthy ecosystems. The puma is currently the most widespread top predator and the carnivore most frequently involved in conflicts with humans in the Americas. We analyzed puma diet in the South American temperate regi...
Carnivores are decreasing globally due in part to anthropogenic ecological disturbances. In Argentina, human activities have fragmented wildlife habitat, thereby intensifying puma–livestock conflict and leading to population control of the predator species by hunting. We investigated genetic variability and population structure of pumas (Puma conco...
El conocimiento de los límites de las poblaciones, su variabilidad genética y el
movimiento de individuos entre las mismas representa un aspecto importante para la
conservación de las especies silvestres. En ese marco, el objetivo general de este trabajo
fue analizar la distribución de la diversidad genética del puma en Argentina,
identificando gru...
In ecologically pristine ecosystems, top-down effects of apex predators play a fundamental role in shaping trophic cascades and structuring ecosystems, but in human-modified landscapes anthropogenic effects may markedly alter the ecological role of predators. In particular, human-provisioned food subsidies represent a serious concern for the conser...
El estudio de la dieta de grandes carnívoros en áreas de intenso conflicto con la ganadería, como es el caso del sur del Espinal para el puma, es importante para entender la relevancia de las especies silvestres y domésticas. En 2014-2016 se recolectaron 16 heces en los partidos de Patagones y Villarino (Provincia de Buenos Aires). La identificació...
A nivel mundial, los ciervos (Familia Cervidae) ocasionan más daño sobre cultivos agrícolas, forestaciones y plantaciones ornamentales que cualquier otra especie de la fauna silvestre. Diferentes métodos, mayormente basados en estímulos odoríferos y/o de sabor, han sido propuestos para repelerlos, obteniéndose distintos niveles de éxito. El ciervo...
Las técnicas de vanguardia que utilizan ADN extraído a partir de excrementos y muestras de tejidos, incluso las de especímenes de museo, han aportado nuevas herramientas para obtener información, antes solo accesible a través de costosas capturas de animales y radiotelemetría. Para éste estudio se analizaron 122 muestras de puma (cueros=47, huesos=...
Debido a sus características biológicas intrínsecas, los mamíferos carnívoros son particularmente vulnerables a la pérdida y fragmentación del hábitat, así como a la persecución humana. Aunque en Argentina el puma está protegido por una Ley Nacional (N° 22.421), la especie se encuentra bajo una alta presión de caza por parte de ganaderos y cazadore...
We investigated puma genetic diversity and population structure in Argentina, increasingly affected by habitat loss, using 40 puma samples including scats, dead animals and museum specimens.
We investigated wolf (Canis lupus) food habits in the National Park of Abruzzo, Lazio and Molise (PNALM, Italy) by scat analysis, accounting for seasonal, annual and inter-pack variation.
Scats collection (2005-2010) involved three different techniques (systematic collection throughout the study area, snow-tracking and rendez-vous site inspection),...
