Aim The persistence of large carnivore populations depends on their survival outside protected areas, where they often impact local livelihoods through livestock depredation. Understanding the impacts of human behaviour on large carnivores in shared landscapes is thus important but is often overlooked in habitat assessments or conservation planning...

We propose the implementation of Conservation Areas in agro-ecosystems in the Chaco Pampeana region of Argentina, recognised as the epicentre of agricultural intensification in the country. These are sectors of variable scale that can be recognised in the rural environment and associated with the productive context, defined as natural, semi-natural...

Aim Land‐use change and overexploitation are major threats to biodiversity, and climate change will exert additional pressure in the 21st century. Although there are strong interactions between these threats, our understanding of the synergistic and compensatory effects on threatened species' range geography remains limited. Our aim was to disentan...

Land-use change is a global threat to biodiversity, but how land-use change affects species beyond the direct effect of habitat loss remains poorly understood. 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 tr...

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...

Land-use change is a root cause of the extinction crisis, but links between habitat change and biodiversity loss are not fully understood. While there is evidence that habitat loss is an important extinction driver, the relevance of habitat fragmentation remains debated. Moreover, while time delays of biodiversity responses to habitat transformatio...

Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade‐offs between them. These trade‐offs are particularly strong in tropical and subtropical deforestation frontiers, yet it remains unclear how changing landscape context in such frontiers alters agriculture–biodiversity trade–offs. We focus on the A...

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...

Abstract Wild aquatic birds are the major reservoir of influenza A virus. Cloacal swabs and feces samples (n = 6595) were collected from 62 bird species in Argentina from 2006 to 2016 and screened for influenza A virus. Full genome sequencing of 15 influenza isolates from 6 waterfowl species revealed subtypes combinations that were previously descr...

The endangered Chacoan peccary ( Catagonus wagneri Rusconi, 1930) has been recorded in western Paraguay, southeastern Bolivia and northern Argentina, reaching the north of Santiago del Estero province. Recently, however, this species was found much further south in central Argentina, ca. 650 km away from the southern limit of its known distribution...

Habitat loss is the primary cause of local extinctions. Yet, there is considerable uncertainty regarding how fast species respond to habitat loss, and how time‐delayed responses vary in space. We focused on the Argentine Dry Chaco ( c . 32 million ha), a global deforestation hotspot, and tested for time‐delayed response of bird and mammal communiti...

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...

El pecarí del Chaco conocido localmente en Para-guay como tagua (Catagonus wagneri) es una es-pecie en peligro de extinción endémica del Chaco Americano, cuya situación se mantiene en dete-rioro como consecuencia de la pérdida y transfor-mación de su hábitat y de la caza excesiva en toda su área de distribución. Este trabajo presenta los resultados...

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...

Esta publicación recopila el trabajo de investigación, extensión y capacitación del equipo de Manejo de Biodiversidad y Gestión Ambiental, durante 22 años, desde 1990 hasta 2011. En la Argentina, los sistemas naturales se han intensificado y/o transformado en las últimas décadas en sistemas productivos, de actividades principalmente agrícolas y for...

In Argentina, the rapid expansion and intensification of row crop production that has occurred during the last 20 years has resulted in the loss of habitat and spatial heterogeneity in agroecosystems. One of the principal effects of industrialized row crop production is the loss of avian diversity and associated ecosystem services that benefit crop...

Avian influenza (AI) viruses have been sporadically isolated in South America. The most recent reports are from an outbreak in commercial poultry in Chile in 2002 and its putative ancestor from a wild bird in Bolivia in 2001. Extensive surveillance in wild birds was carried out in Argentina during 2006-2007. Using RRT-PCR, 12 AI positive detections...
