Introduction
I'm a biologist interested in vertebrate-plant interactions, ecology, conservation, and biology of subterranean mammals. Our lab (INTERBIODES) addresses a variety of topics including effects of perturbation such as roads and tourism on vertebrate populations and communities. Our research team conducts field research in locations including cold and temperate deserts (Puna and Monte), and several protected areas (e.g. Ischigualasto, El Leoncito, Don Carmelo).

Human-wildlife interactions, poaching and illegal wildlife trade in particular, are among the major threats to biodiversity around the world, causing species and population extinctions, zoonotic diseases dissemination, and exotic species invasions, among others. Here we assessed the patterns of poaching and illegal wildlife trade in western Argenti...

The mara is a large endemic rodent, which presents a marked decline in its populations, mainly because of habitat loss, hunting, and overgrazing. The Ischigualasto Provincial Park is a hyper-arid protected area at the Monte Desert of Argentina with an overall low plant cover. Our objective was to determine the influence of environmental variables a...

Plant emergence from seed banks and from asexual reproduction could be strongly influenced by environmental and biological factors. Among environmental factors, animal disturbances deserve special consideration. In this study we test the hypothesis that disturbances resulting from the burrowing activity of Ctenomys affect plant emergence (sexual an...

Leucism appears in various groups of vertebrates, although it is rare in mammals. For Argentina, we do not know of any documented registry for small rodents. The objective of our work is to report the first cases of leucism in cricetid rodents in the Puna Desert of Argentina. Field work was carried out in the Multiple Use Provincial Reserve Don Car...

The effects of roads on natural environments have been studied in many places around the world. The presence of roads can be considered for native animals as a disturbance stimulus. Besides, roads can facilitate arrival and entry of alien species, such as domestic and feral ungulates, which sometimes compete with native species. Due to this, we ass...

Highlights • Pesticide poisoning is currently the greatest threat to the Andean condor. • Poisonings affect adult condors more than immature ones. • The most commonly used poison is Carbofuran, and to a lesser extent Palation. • Condor poisonings have reached alarming levels that could lead to extinction.

Roads can affect animals as well as their habits at different levels. Avoidance behavior is a common response of animals to this type of perturbation, preventing access to areas rich in resources. The effects of roads on ungulates have not been studied in South America extensively, especially in arid environments. We have studied the space use by u...

En Sudamérica los desiertos ocupan una importante extensión, llegando a cubrir en Argentina el 69% de su superficie. Si bien los micromamíferos del desierto del Monte han sido objeto de numerosos estudios, no ha ocurrido lo mismo con los micromamíferos de los desiertos de altura. Por este motivo, los objetivos de este trabajo fueron analizar la abu...

Este estudio recopila los registros de especies endoparasitarias en guanacos (Lama guanicoe) de Argentina. Se hizo una revisión bibliográfica de los trabajos científicos publicados entre 1967 y 2017. Además, se incorporaron nuevos registros inéditos de localidades dentro de la provincia de San Juan. La fauna de endoparásitos estuvo representada por...
Article
Selection occurs when animals choose from among alternative habitat resources they find available in the environment. As selection is a hierarchical process, it can be studied at multiple spatial scales. Subterranean rodents are a good model to study habitat selection because of their low dispersal ability and easily identifiable perturbed areas. U...

Attributes such as sex, age and pigmentation of individuals could correspond to the competitive skills they use to access resources and, consequently, determine their social status when a hierarchy of dominance is established. We analysed patterns of social dominance in relation to sex, age and, for the first time, according to face pigmentation in...

Human-wildlife conflicts currently represent one of the main conservation problems for wildlife species around the world. Vultures have serious conservation concerns, many of which are related to people's adverse perception about them due to the belief that they prey on livestock. Our aim was to assess local perception and the factors influencing p...

Animals may divert time and energy in similar ways in the presence of predators, humans or landscape infrastructures. Roads have facilitated the economic and social development of human populations. Nevertheless their presence and human use cause environmental changes, such as clearing, which increase perception of predation risk. Among the respons...

In arid and semiarid ecosystems, subterranean herbivorous rodents play an important role in determining the composition, function, and structure of plant communities. We hypothesized that in a high-altitude cold desert in the southern Puna region of Argentina, Ctenomys mendocinus (mendocino tuco-tuco), a subterranean herbivorous rodent, may increas...

A rocky habitat, in its broadest sense, may be described as any locality that contains boulders, rocks, scree, pebbles, outcrops, cliffs, or caves. In these habitats, mammals find shelter sites that they use as nesting sites or dens to raise their young in a stable microclimate that is relatively secure from predators. The aim of this study was to...

Mammals that live in arid and semi-arid environments in South America present physiological mechanisms that enable them to conserve water. Body water is lost through the kidneys, lungs, skin, and intestines. Regarding renal adaptation for water conservation, several indices have been used to estimate the capacity of the kidneys to produce a maximum...

Naturalized herbivores can cause the extinction of native plant through their effect on plant reproduction, and can compete for the use of resources with native herbivores. In Ischigualasto Provincial Park, we assessed the effect of feral donkey's herbivory on columnar cacti Echinpsis terscheckii and the potential overlapping in the use of food res...

The small cavy Microcavia australis, a social and fossorial rodent, inhabits a large distribution range in South American arid zones. The species is versatile in coping with the seasonal and spatial variability typical of these environments through changes in morphology, physiology, and behavior. In order to explore whether phenotypic variations ar...

The fate of Prosopis flexuosa seeds dispersed by cattle is dependant on the spatial pattern of dung deposition and foraging movements. We hypothesised that cattle-use site classes explain the response variables related to seed input and fate of seeds, seedlings and saplings (small plants more than one year old). We defined sites with heavy cattle t...

Analyzing coexistence of exotic and native ungulates in arid areas is important from both a theoretical and a species conservation perspective. We assess the habitat use patterns and possible interference between guanaco (Lama guanicoe) and feral livestock (donkey and cattle) in arid environments of South America. To determine habitat use and niche...

Foraging strategies have traditionally been modelled as a result of food selection in response to one factor, as for instance resource availability, deterrent compounds or nutrients. Thus, a trade-off is assumed between plasticity (generalist strategy) and efficiency (specialist strategy). Nevertheless, several studies have demonstrated that animal...

It has been shown that seasonal changes, especially in arid areas have a large influence on gonadal changes of the species that inhabit these areas. We studied a wild hystricomorph Microcavia australis in its natural habitat in the arid Andes Mountains. Sampling of adult males was carried out every 2 months. After autopsy, testes and epididymides w...

We examined the removal of Prosopis flexuosa pods by small rodents, and addressed four specific questions: (1) do Monte Desert small rodents remove mesquite pods? (2) if they do, do they store them above-ground? (3) how far are pods carried? and (4) what condition are removed pods and seeds in? We carried out the experiments in March 2000 and June...

Ecological physiology examines how animals cope with changing environmental demands. In low-productivity desert habitats, small mammals should consume low-quality, high-fiber food as a consequence of necessity rather than by choice. Diet quality of populations can differ at both spatial and temporal scales. Nevertheless, spatial and temporal variat...
