In vitro micrografting as an innovative strategy for the vegetative propagation of algarrobo blanco (Neltuma alba) by Carloni, Edgardo José, Rodriguez, Milena Nahir, Verga, Anibal, Grunberg, Karina

“…Neltuma alba (Formerly Prosopis alba), known as ‘algarrobo blanco,’ is a native species of great biological, productive, and cultural importance in the phytogeographic regions of the Gran Chaco and the Espinal. However, it faces severe conservation threats due to deforestation and unsustainable management of native forests. …”

Using occupancy models to assess the direct and indirect impacts of agricultural expansion on species’ populations by Semper Pascual, Asunción, Decarre, Julieta, Baumann, Matthias, Camino, Micaela, Di Blanco, Yamil, Gómez Valencia, Bibiana, Kuemmerle, Tobias

“…We developed an approach to isolate and map the direct and indirect effects of agricultural expansion on species of conservation concern, using the threatened giant anteater (Myrmecophaga tridactyla) in the Gran Chaco as an example. We reconstructed anteater occupancy change between 1985 and 2015 by fitting single-season occupancy models with contemporary camera-trap data and backcasting the models to 1985 and 2000 land-cover/use maps. …”

Distribución natural y características morfológicas de las especies de algarrobo con valor forestal de Argentina by Vega, Carmen Delcira, Aguilar, Dana Lucía, Cosacov, Andrea, Acosta, María Cristina, Sérsic, Alicia, Cisneros, Ana Belén, Moglia, Juana, Bender, Adrián, Fagúndez-Pachón, César, Verga, Anibal

“…Según Burkart (1976), el género Prosopis comprende aproximadamente 44 especies de árboles y arbustos distribuidos en zonas áridas, semiáridas y subhúmedas principalmente de América, aunque algunas pocas especies son nativas de África y Asia occidental. El “Gran Chaco Americano” constituye el principal centro de diversidad del género, ya que alberga el mayor número de endemismos y de especies que el resto de las ecorregiones de América (Burkart, 1976; Ferreyra et al., 2010). …”

Partitioning the effects of habitat loss hunting and climate change on the endangered Chacoan peccary by Torres, Ricardo, Kuemmerle, Tobías, Baumann, Mattias, Romero-Muñoz, Alfredo, Altrichter, Mariana, Boaglio, Gabriel, Cabral, Hugo, Camino, Micaela, Campos Kraver, Juan M., Giordano, Anthony J., Cartes, José L., Cuéllar, Rosa L., Decarre, Julieta, Gallegos, Marcelo, Lizarraga, Leónidas, Maffei, Leonardo, Neris, Nora N., Quiroga, Verónica, Saldivar, Silvia, Tamburini, Daniela

“…Our aim was to disentangle the impact of habitat loss, hunting and climate change on spe cies, using the example of the endangered Chacoan peccary (Catagonus wagneri). Location: Gran Chaco ecoregion in South America. Methods: Using a large occurrence database, we integrated a time-calibrated species distribution model with a hunting pressure model to reconstruct changes in the distri bution of suitable peccary habitat between 1985 and 2015. …”
