(Elsevier, 2012-04)
In Argentina, American Cutaneous Leishmaniasis (ACL) extends up to 29°S in the phytogeographic regions of the Yungas (west), Chaco (center) and Paranaense (east). Since the Phlebotominae vectors of this disease in the ...
Natural grasslands in the Chaco. A neglected ecosystem under threat by agriculture expansion and forest-oriented conservation policies
(Elsevier, 2015-12)
In most tropical and subtropical biomes, conservation strategies are mainly focused on the preservation of forests. However, neotropical dry forest and savanna ecoregions include open habitats that may deserve conservation ...
From biophysical to social-ecological trade-offs: Integrating biodiversity conservation and agricultural production in the Argentine Dry Chaco
(Resilience Alliance, 2015-01)
Agricultural intensification in rural areas of developing countries compromises the provision of ecosystem services. Social conflict arises among landholders with different preferences for ecosystem services and land-use ...

Measuring forest fragmentation using multitemporal remotely sensed data: three decades of change in the Dry Chaco
(Italian Society of Remote Sensing, 2014-12)
We introduce an approach based on remotely sensed data to summarize forest fragmentation over time, which specifically accounts for the interdependencies between landscape composition and configuration changes. The proposed ...
Impacts of agricultural intensification on avian richness at multiple scales in Dry Chaco forests
(Elsevier, 2014-11)
Agricultural expansion and intensification is driving rapid landscape modification in the South American Gran Chaco, affecting biodiversity at multiple spatial scales. Research on biodiversity change in modified landscapes ...
