Seedling habitat structure in dry Chaco forest (Argentina)

Journal of Arid Environments, 2000
Abstract We hypothesized that seedlings of different dominant species in the dry Chaco forests of Cordoba Province were restricted to patches with particular microenvironmental conditions. To test this hypothesis, the seedling habitat was characterized by measuring physical and biotic microhabitat variables such as incident light, distance to the ...

The disappearing Dry Chaco, one of the last dry forest systems on earth

Landscape Ecology, 2021
The Dry Chaco spans more than 87 million hectares across Argentina, Bolivia, and Paraguay. This unique forest system has experienced extensive loss and fragmentation due to land-use change, with different land-use histories in the three countries. This forest loss has altered landscape connectivity for the Dry Chaco’s associated biota.

Hunting practices and harvest of peccaries in the northern Paraguayan Dry Chaco

Biological Conservation, 2021
Abstract Overexploitation is a frequently cited driver of species extinction. Throughout the Neotropics, balancing traditional practices and the needs of local people with protection of rare or declining species is challenging, especially given low capacity for control by authorities. We conducted interviews with wildlife professionals and residents,

Factors affecting nitrogen dynamics in a semiarid woodland (Dry Chaco, Argentina)

Plant and Soil, 1991
In an effort to elucidate the factors affecting soil N dynamics in the Dry Chaco ecosystem, soil respiration and microbial biomass N were measured for one year underneath 5 vegetation types: a leguminous tree (Prosopis flexuosa DC), a non-leguminous tree (Aspidosperma quebracho-blanco Schlecht.), a non leguminous shrub (Larrea spp.), the open ...

Phenology of a Lizard Assemblage in the Dry Chaco of Argentina

Journal of Herpetology, 1999
Individual species' phenologies can play an important role in the structure of lizard assem- blages over short time scales. Data from a pitfall study carried out in the dry Chaco of Argentina were used to address the question of how species are distributed in their assemblage through time. Lizard activity and species richness were highest in the spring
