Deforestation continues across the tropics at alarming rates, with repercussions for ecosystem processes, carbon storage and long term sustainability. Taking advantage of recent fine-scale measurement deforestation, this analysis aims to improve our understanding scale deforestation drivers in tropics. We examined trends forest clearings different sizes from 2000–2012 by country, region development level. As tropical increased approximately 6900 kha yr−1 first half study period, >7900 second...
Abstract Livestock are a critical part of our food systems, yet their abundance globally has been cited as driver many environmental and human health concerns. Issues such soil, water, air pollution, greenhouse gas emissions, aquifer depletion, antimicrobial resistance genes, zoonotic disease outbreaks have all linked to livestock operations. While studies examined these issues at depth local scales, it difficult complete regional or national scales due the dearth data, hindering pollution...

Hurricanes that damage lives and property can also impact pollutant sources trigger poor water quality. Yet, these quality impacts affect both human natural communities are difficult to quantify. We developed an operational remote sensing-based hurricane flood extent mapping method, examined potential implications of two "500-year" hurricanes in 2016 2018, identified options increase social-ecological resilience North Carolina. Flooding detected with synthetic aperture radar (>91% accuracy)...
Human-induced climate change is bringing warmer conditions to the Southwestern United States. More extreme urban heat island (UHI) effects are not distributed equally, and often impact socioeconomically vulnerable populations most. This study aims quantify how land surface temperature (LST) changes with increasing green vegetation landscapes, identify disparities in warming exposure, provide a method for developing evidence-based mitigation options. ECOSTRESS LST products, detailed use cover...
Interferometric Synthetic Aperture Radar (InSAR) time series analysis is a powerful technique to estimate long-term water level changes in wetlands ecosystems. However, few studies have applied InSAR on that are highly segmented by canals and levees due part the challenge of selecting qualified reference points minimize unwrapping errors, which, contrast, relatively easy task for unsegmented wetlands. Here we developed new method automatically select optimal point analysis. The selects...
Over 50% of Western Hemisphere shorebird species are in decline due to ongoing habitat loss and degradation. In some regions high wetland loss, shorebirds heavily reliant on a core network remaining human-managed wetlands during migration journeys the spring fall. While most refuges have been designed managed match needs waterfowl, typically require much shallower water (<10 cm deep). Traditional static modeling approaches at relatively coarse spatial temporal resolution insufficient capture...
SUMMARY To avoid extinction of rare species in regions active environmental change, strategic approaches are needed to manage remaining habitat. When observations dispersal or metapopulation information not available, habitat connectivity simulations may offer a valuable alternative source assess threats and evaluate conservation options. For the Critically Endangered San Martin titi monkey ( Callicebus oenanthe ) north central Peru, an updated distribution model was generated land cover...
Animal movements are inherently linked to landscape structure. Understanding this relationship for highly-mobile species requires documenting their responses spatiotemporal variability of resources. To that end, characterizing movement behaviors and resource distributions using the principles habitat connectivity facilitates coordinated planning efforts within highly modified landscapes. We tracked locations 156 dunlin (Calidris alpina) 109 long-billed dowitchers (Limnodromus scolopaceus)...
California has lost most of its historical wetlands and it is in urgent need to conserve protect the remaining wetlands. One key elements for wetland management monitoring changes surface water depths, which challenging due inaccessibility dynamic hydrology Particularly, many are privately owned with small areas (e.g., 40 ha) bounded by levees, resulting differences hydrological regimes. Managed characterized high depths winter season low summer season, a rapid transition between....
Abstract Surface water in arid regions is essential to many organisms including large mammals of conservation concern. For little known about the extent, ecology and hydrology ephemeral waters, because they are challenging map given their nature small sizes. Our goal was advance surface knowledge by mapping monitoring from wet dry seasons across Kavango–Zambezi Transfrontier Conservation Area southern Africa (300 000 km 2 ). We mapped individual waterholes for six time points each year...
Canada's abundant and high-quality water resources support a growing human population, as well thriving industrial agricultural economies. However, recent intense drought conditions have raised concerns for current resource availability. Patterns of long-term ground surface (GSW) changes, their response to environmental conditions, land-use dynamics, socioeconomic changes are not well-understood across this large diverse country. To address crucial gap, we identified regions in all the...
Among the most biodiverse environments in world, Mekong River Basin has experienced extensive socio-economic development past few decades resulting land use change and associated ecological environmental stresses. To assess possible impacts on sensitive ecosystems their services Lower (LMB), we examine spatial temporal changes forest community extent, as well tree density canopy coverage, relation to carbon uptake climate change. We employed Mann–Kendall test identify regions of likely...
