Article
In the context of the global climate and biodiversity crises, forecasting the effectiveness of Protected Areas (PAs) and forest management to conserve biodiversity in the long-term is a high priority, especially in threatened environments. By combining distribution models and conservation planning protocols, we analyzed the effect of global climate...

Hispaniola shows the highest environmental heterogeneity among the Greater Antilles mainly due to its complex land relief, encompassing a high ecosystemic heterogeineity, and bats as one o the most representative group of vertebrates. However, the island remains the least studied in the greater Antilles. In this work, we present a first comprehensi...
Article
Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are often unclear, as well as how deforestation or different policies alter the option space of available pathways. Using a spatial o...

Context Better balancing agricultural production and biodiversity conservation is a central goal for many landscapes. Yet, empirical work on how to best achieve such a balance has focused mainly on the local scale, thereby disregarding that landscape context might mediate biodiversity-agriculture trade-offs.

Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of these threats is lacking, including where they overlap and how they change over time. These knowledge gaps are real barriers for...

The Chacoan peccary Catagonus wagneri is the rarest and most threatened of the three extant species of pec-cary. Its presence has been recorded in the northern Dry Chaco ecoregion, which spans northern Argentina, western Paraguay and southeastern Bolivia. However, distribution models based on its occurrence in Argentina have predicted that suitable...

The subtropical dry forests are experiencing rapid clearing in the southamerican Great Chaco region, mainly for soybean production in Argentina. This is causing biodiversity loss and soil salinization. This forests are unique for the floristic richness and the dense forest cover in a region characterized by semiarid climatic conditions. The authors...

Una de las medidas de mitigación del cambio climático más fomentadas es el secuestro de carbono por vegetación. Esto depende de la velocidad de captación y transformación del carbono en biomasa, velocidad de liberación a través de la respiración y estabilidad del stock ante disturbios. La diversidad forestal influye sobre estos factores, cuya efici...

Abstract The Chacoan peccary (Catagonus wagneri), or Tagua, an endemic species living in the Chaco ecoregion, is endangered by highly increasing deforestation rates across the region, particularly in the last decade. This situation highlights the need to better understand the current distribution of the species, as well as how environmental conditi...

La Sierra de Guasayán es un área importante para la conservación de las aves (AICA SE05) de Argentina. Los estudios sobre su avifauna son escasos, a pesar de que la investigación debe desarrollarse en las AICAs con información insuficiente. Por ello, con este estudio abordamos las respuestas de las comunidades de aves a las características (factore...

The biota inhabiting the Suquía River Basin is described in this chapter. Comments on the species of fish, birds, invertebrates and aquatic plants registered in this system are included. Along the basin, different factors generate a noncontinuous mosaic of abiotic conditions at temporal and spatial levels, which, in turn, structure the biotic commu...

Despite having a moderately large distributional area, both the pink fairy armadillo (Chlamyphorus truncatus) and particularly the Chacoan fairy armadillo (Calyptophractus retusus), which are among the least known xenarthrans, appear to be rare or patchily distributed. Although low density in species with large range sizes has been associated with...
Article
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 attention. We analyzed the historical patterns and potential distribution of natural grasslands, as well as their biodiversity...
