Resilience "the capacity of an ecosystem to recover from disturbance" is a popular concept but quantitative empirical studies are still uncommon. This lack of empirical evidence is especially true for semi-arid ecosystem...

At a regional scale, habitat heterogeneity can play a very important role in allowing the coexistence of species through their specialization in the use of patches differing in environmental conditions. Here, we explore ...

Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promotin...

Deforestation poses a significant threat to natural ecosystems, particularly in Argentina’s Chaco region—one of the world’s most rapidly changing forest areas. This study focuses on the detection of sudden deforest...

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 propo...

Agricultural expansion threatens biodiversity due to habitat loss and fragmentation. In the Gran Chaco, a global deforestation hotspot, rampant cropland and pasture expansion raise concerns about the sustainability of th...

Anthropogenic alteration of tropical and subtropical forests is a major driver of biodi-versity loss, with the Chaco forest, the largest dry forest in the Americas, among the most impacted regions. Sustainable forest man...

The large genus Calliopsis (Andrenidae, Panurginae) is composed of ten subgenera with polylectic and presumably oligolectic species. These categories have been mainly developed from floral visits of female bees collectin...

Flower traits under selection by specialized pollinators may experience a decrease in their phenotypic variation. Another viewpoint suggests that flower traits of plants under selection by generalized pollinators could d...

The pollen preferences of three Meliponini species (Geotrigona argentina, Scaptotrigona jujuyensis and Tetragonisca fiebrigi) were studied in the Chaco forest of South America. Surprisingly, a large number of pollen type...

Abstract This contribution provides a brief description of the harvest of stingless bee honey by Creole people in the Chaco forest from the informal “meleo” which is the collection of bee colony products mostly ho...

During the past decades, the Ecological Modernization Theory, and associated ideas such as the Forest Transition Theory and Land Sparing Hypothesis, have dominated the academic and policy arenas regarding the solutions t...

Este estudio comparamos las comunidades de arañas de bosques y pastizales en la Estancia San Francisco y la Estancia San Carlos; Sitio RAMSAR, Humedales Chaco. Los ejemplares de arañas las recolectaromos mediante las t...

The ecological condition of forest ecosystems is degraded. Limited prior research in vegetationhas focused on monitoring ecological condition levels in dry forest at fine scale. We proposeda novel approach to obtain accu...

El objetivo de este artículo fue comparar la estimación de biomasa aérea total obtenida mediante ecuaciones alométricas locales con aproximaciones generales de la bibliografía en el Chaco Salteño argentino. Se real...

The central Andean rainforests and the Atlantic Forest are two similar biomes that are fully isolated by xerophytic and open-vegetation regions (the Chaco and Cerrado, respectively). Even though there is evidence suggest...

Latin American subtropical dry ecosystems have experienced significant human impact for more than a century, mainly in the form of extensive livestock grazing, forest products extraction, and agriculture expansion. We as...

Tropical dry forests and savannas provide important ecosystem services and harbor high biodiversity, yet are globally under pressure from land-use change. Mapping changes in the condition of dry forests and savannas is t...

Ethnopharmacological relevance This article presents the results of a study on wild plant pharmacopeia and medical ethnobotany of the Wichí people of the South American Gran Chaco region, where native forest still persi...

The Chacoan peccary Catagonus wagneri is the rarest and most threatened of the three extant species of peccary. Its presence has been recorded in the northern Dry Chaco ecoregion, which spans northern Argentina, western ...

The aim of this study was to analyze the physico-chemical properties of honey produced in the province of Chaco, as a contribution to the characterization of these honeys. Color, moisture, electrical conductivity, total ...

Bothrops diporus is a mid-sized pitviper found in southern Brazil, southern Paraguay, central and northern Argentina, and probably extreme south-central Bolivia. Although it is common in a variety of habitats including C...

Owl monkeys are small monogamous primates ranging over a wide area extending from Panamá to the Chaco region of northern Argentina. The Chaco, an alluvial plain covering over one million km2 of Argentina, Bolivia, Brazi...
