Carbon emissions from land-use changes in tropical dry forest systems are poorly understood, although they likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion and intensification, cattle ranching soybean cultivation expand into forests, replaces grazing lands. Still, our knowledge the rates spatial patterns these how affected carbon remains partial. We used Landsat satellite image archive to reconstruct change over past 30 years...
Understanding the factors related to invasive exotic species distributions at broad spatial scales has important theoretical and management implications, because biological invasions are detrimental many ecosystem functions processes. Housing development facilitates by disturbing land cover, introducing nonnative landscaping plants, facilitating dispersal of propagules along roads. To evaluate relationships between housing distribution we asked (1) how strongly is associated with plants...
Theories of frontier expansion in the last four decades have been mostly shaped by studies state-driven smallholder colonization. Modern-day agricultural frontiers, however, are increasingly driven capitalized corporate agriculture operating with little direct government intervention. The contemporary frontiers has explained existence spatially heterogeneous "abnormal" rents, which can be caused cheap land and labor, technological innovation, lack regulations, a variety other incentives....
Abstract Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012. However, little is known about spatial temporal patterns of fires their relationship climate vegetation this area. Such information great value for fire risk assessment development strategies management. Our main objective was to analyze activity four sierran ranges, assessing which weather conditions were mostly related activity, land cover types...
Significance Millions of people globally rely on forest-based resources for their livelihoods, particularly in the tropics and subtropics. Deforestation is often hypothesized to diminish forest-dependent communities’ resource base push them toward more-marginal environments, but such ecological marginalization has rarely been quantified. We developed an approach identify homesteads track over 30 y across entire South American Gran Chaco (1.1 million km 2 ). This highlighted that are...
Land-use change is a root cause of the extinction crisis, but links between habitat and biodiversity loss are not fully understood. While there evidence that an important driver, relevance fragmentation remains debated. Moreover, while time delays responses to transformation well-documented, time-delayed effects have been ignored in versus debate. Here, using hierarchical Bayesian multi-species occupancy framework, we systematically tested for bird mammal communities fragmentation. We...
Land use is a key driver of the ongoing biodiversity crisis and therefore also major opportunity for its mitigation. However, appropriately considering diversity land-use actors activities in conservation assessments planning challenging. As result, top-down policy are often criticized lack contextual nuance widely acknowledged to be required effective just action. To address these challenges, we have developed conceptually consistent, scalable land system typology demonstrated usefulness...
Abstract Understanding how biodiversity responds to intensifying agriculture is critical mitigating the trade‐offs between them. These are particularly strong in tropical and subtropical deforestation frontiers, yet it remains unclear changing landscape context such frontiers alters agriculture–biodiversity trade–offs. We focus on Argentinean Chaco, a global hotspot, explore shapes trade‐off curves agricultural intensity avian biodiversity. use space‐for‐time approach integrate large field...
Moisture content of live fuels (LFMC) is one the main factors determining fuel flammability and, therefore, a key indicator fire danger. In this study, we modeled relationship between spectral indices derived from satellite imagery and field estimations LFMC in Chaco Serrano subregion; then, analyzed danger based on calculations activity. Empirical models fitted for grasslands, forests, glossy privet forests may be considered very accurate R <sup...
