Introduction
My main interest is understanding the consequences of human activities on medium-large mammal conservation, and the social-ecological factors that affect human-wildlife coexistence in different SES of Latin America, with focus on the Argentine Dry Chaco. I particularly seek to work jointly with stakeholders to co-design strategies fostering coexistence and biodiversity conservation that are aligned with the interests, needs and possibilities of the people sharing the land with wildlife.

PRESENTACIÓN Buena parte de los tucumanos viven en lo que se conoce como el Gran San Miguel de Tucumán: Yerba Buena, Tafí Viejo, Lules, La Banda, El Manantial, Las Talitas y San Miguel de Tucumán, con alrededor de un millón de tucumanos, son vecinos de la Sierra de San Javier. Esa sierra fue durante siglos fuente de madera y de pastos verdes para...
Article
Human settlement into rural areas (counterurbanization) is generating new patterns of reforestation, with distinctive features compared to the previously considered pathways of forest transition through “economic development” and “forest scarcity”. Here, we discuss the specific features of this neglected pathway of forest recovery and describe the...

Human-carnivore conflicts threaten the survival of large carnivore populations and impose high costs for humans. Knowledge co-building approaches can be successful in tackling these problems. We examined conflicts between the puma (Puma concolor) and pastoralists from an Argentine Puna village through semi-structured interviews and a focus group di...

Habitat loss is a significant threat to biodiversity worldwide, and the Argentine Dry Chaco is one of the most active global deforestation hotspots. Medium-large mammals are especially vulnerable to land-cover change, and in the Dry Chaco, they are subjected to the combined effect of habitat loss and hunting. In agroe-cosystems, blocks of natural h...

As an apex predator, pumas (Puma concolor) frequently enter into conflict with humans because of predation on livestock. We analyzed the association between puma predation and human tolerance in six agroecosystems of the Argentine Dry Chaco, a global deforestation hotspot. Specifically, we addressed attitudes and behaviors of local social actors to...

Leopardus colocola (Molina, 1782) is a poorly known small felid distributed throughout a large portion of South America, reported as extinct in the Pampas of Argentina, and absent from a large portion of the Argentine Dry Chaco. We compile data from the field and national collections to report new occurrence records of this species from the Dry Cha...

In most of the planet, large herbivore communities have been replaced by livestock, but this process is reversing in many places. Here, we outline and review the pathways of “megaherbivore rewilding transitions” in three social-ecological-systems of subtropical Argentina. In the extensive arid high-elevation Puna plateau we observed a “rapid rewild...

Disparity between the knowledge produced and knowledge required to address complex environmental challenges, such as biodiversity conservation and climate adaptation, continues to grow. Systems thinking under the Open Standards for Conservation framework can help close this gap by facilitating interdisciplinary engagement, advancing conversations o...

The Dry Chaco is mostly known as a forested ecosystem. However it includes natural grasslands, savannas, scrublands, and wetlands. With one of the highest global deforestation rates in the last two decades and only 12% of the area protected, the concern about land-use change in this ecoregion has raised exponentially; but conservation initiatives d...
Article
Tropical reforestation is a significant component of global environmental change that is far less understood than tropical deforestation, despite having apparently increased widely in scale during recent decades. The regional contexts defining such reforestation have not been well described. They are likely to differ significantly from the geograph...

New forests are expanding around the world. In many regions, regrowth rates are surpassing deforestation rates, resulting in “forest transitions,” or net gains in forest cover. Typically measured only in terms of aggregate“’forest cover” change, these new forests are ecologically distinct from each other and from those originally cleared. We ask, w...

Areas of land abandonment and agriculture expansion usually differ in location and associated environmental characteristics; thus, land-use redistribution affects the provision of ecosystem services and biodiversity conservation. In a subtropical region undergoing land redistribution patterns characteristic of Latin America, we estimated 20-year ch...

This study represents the first analysis of livestock influence over individual mammal species in NW Argentina forests. Through camera-trapping, I found a negative correlation between frequencies of occurrence of livestock (sheep, goats and cattle) and Gray brocket deer Mazama goauzoubira, and a modification of the daily activities patterns of the...

Patterns of land-use and land-cover change are usually grouped into one of two categories defined by the dominant trend: (1) deforestation resulting from expanding agriculture and (2) forest expansion, usually related to the abandonment of marginal lands. At regional scale, however, both processes can occur simultaneously even in the absence of net...

We studied the diet of the Common Barn-Owl (Tyto alba) in the Dry Chaco of Santiago del Estero, Argentina. From 332 pellets collected between 2007 and 2009 we analyzed the seasonal variation in number and biomass of prey-items, diversity, and trophic niche width. We identified 1170 individuals belonging to 14 prey-items, corresponding to mammals (8...

Project
The main goal of this project is to evaluate medium-large mammal persistence in agroecosystems of the Argentine Dry Chaco, by addressing both their presence and habitat use; and the local population attitudes towards them. This will be achieved through 3 specific objectives: 1. Medium-large mammal (MLM) ecology in Argentine Dry Chaco agroecosystems. We will assess MLM presence, activity patterns, and habitat use in agroecosystems of the Argentine Dry Chaco; and will investigate the effects of the anthropic land-uses that characterize these agroecosystems on these species. We will especially address the potential of silvopastoral systems to harbor MLM, since this recent land-use is widely spread in the region, yet its sustainability has not been evaluated. 2. Interactions, perceptions and conflicts between MLM and humans in Argentine Dry Chaco agroecosystems. We will characterize the interactions between the different stakeholders of the region (e.g., local peasants, small landowners, large landowners) and MLM, including the quantification of livestock and poultry predation by carnivores. 3. Educational and participatory workshops and local dissemination of the results, to generate awareness on MLM; share the results of our project; and as a first step to identify possible, socially suitable actions for the mitigation of conflicts between people and MLM in the region. _____________________________________________________________________ El principal objetivo de este proyecto es evaluar la persistencia de mamíferos medianos-grandes (MMG) en agroecosistemas del Chaco Seco Argentino, analizando su presencia y uso del hábitat; y las actitudes de los actores sociales hacia estos. Este objetivo general será alcanzado mediante 3 objetivos específicos: 1. Ecología de MMG en agroecosistemas del Chaco Seco argentino: Evaluaremos la presencia, patrones de actividad y uso del hábitat de MMG en agroecosistemas del Chaco Seco argentino; y analizaremos el efecto de los distintos usos antrópicos del suelo sobre estas especies. Analizaremos específicamente el potencial de los sistemas silvopastoriles para conservar MMG, dado que este manejo del suelo se está expandiendo en la región. 2. Interacciones, percepciones y conflictos entre MMG y humanos en agroecosistemas del Chaco Seco argentino: caracterizaremos las interacciones entre distintos actores sociales de la región (productores grandes, pequeños, puesteros) y MMG, incluyendo la cuantificación de los eventos de depredación de ganado por parte de carnívoros. 3. Desarrollo de talleres participativos y educativos, y difusión local de los resultados, como primer paso para identificar posibles acciones socialmente aceptadas para la mitigación de los conflictos entre humanos y MMG en la región.
Project
This Project aims at describing land-use/cover changes in Latin America (LA) in the most complete and detailed way for the 21st century (2001-2020). It relates these changes to global and regional drivers of change (e.g., commodity markets, population) and explores the consequences of these processes on the efficiency of territorial use (i.e., compatibility and stability of agricultural production, biodiversity conservation and biomass preservation) in the different ecoregions of Latin America).
