Ecological condition indicators for dry forest: Forest structure variables estimation with NDVI texture metrics and SAR variables
Alvarez, María Paula; Bellis, Laura Marisa; Arcamone, Julieta Rocio; Silvetti, Luna Emilce; Gavier Pizarro, Gregorio Ignacio (Elsevier, 2025-01)The ecological condition of forest ecosystems is degraded. Limited prior research in vegetation has focused on monitoring ecological condition levels in dry forest at fine scale. We proposed a novel approach to obtain ... -
Functional Connectivity in Future Land-Use Change Scenarios as a Tool for Assessing Priority Conservation Areas for Key Bird Species: A Case Study from the Chaco Serrano
Arcamone, Julieta Rocio; Silvetti, Luna Emilce; Bellis, Laura Marisa; Baldini, Carolina; Alvarez, María Paula; Naval-Fernández, María Cecilia; Albornoz, Jimena Victoria; Gavier Pizarro, Gregorio Ignacio (MDPI, 2025-07)Planning conservation for multiple species while accounting for habitat availability and connectivity under uncertain land-use changes presents a major challenge. This study proposes a protocol to identify strategic ... -
Land-Use Change Scenarios and Their Implications for Bird Conservation in Subtropical Forests
Silvetti, Luna Emilce; Arcamone, Julieta Rocio; Gavier Pizarro, Gregorio Ignacio; Landi, Marcos A.; Bellis, Laura Marisa (MDPI, 2025-06)(1) Background: Land-use change threatens biodiversity globally, making it essential to anticipate future impacts.
