  • Repeated mining accounts for the majority of artisanal and small-scale gold mining activity in Southeastern Peru

    Open AccessRachel C Engstrand, Jorge Caballero et al.ARTICLEEnvironmental Research Letters2024

    Artisanal and small-scale gold mining (ASGM) is considered a leading cause of environmental degradation in the Amazon. Previous studies have only used deforestation to quantify total ASGM activity and have not considered that mining may occur multiple times in the same area. However, miners often revisit previously mined sites to extract additional gold, though the frequency and extent of this occurrence remains unquantified. This study is the fi…

  • Global analysis of benthic complexity in shallow coral reefs

    Open AccessJiwei Li, Gregory P AsnerARTICLEEnvironmental Research Letters2023

    Three-dimensional shallow benthic complexity (also known as benthic rugosity) reflects the physical conditions of shallow coral reefs environments and can be used to estimate fish biomass and coral cover on reefs. Spatially explicit data on benthic complexity could offer critical information for coral reef conservation and management. However, benthic complexity has not yet been mapped at a global scale. We mapped global shallow water benthic com…

  • Anomalous sea temperatures can impair coral reef fish recruitment

    Open AccessShawna A Foo, Rachel R Carlson et al.ARTICLEEnvironmental Research Letters2023

    Understanding how temperature affects coral reef fish recruitment success is crucial for assessing impacts of ocean warming on coral reef resilience. We utilized a long-term fish survey dataset along the west coast of Hawai‘i Island to investigate the role of sea surface temperature (SST) in influencing recruitment timing and density. The dataset consisted of 17 years of surveys, with 25 sites annually surveyed in the months of May, July, Septemb…

  • Methane remote sensing and emission quantification of offshore shallow water oil and gas platforms in the Gulf of Mexico

    Open AccessAlana Ayasse, Andrew K Thorpe et al.ARTICLEEnvironmental Research Letters2022

    Offshore oil and natural gas platforms are responsible for about 30% of global oil and natural gas production. Despite the large share of global production there are few studies that have directly measured atmospheric methane emanating from these platforms. This study maps CH 4 emissions from shallow water offshore oil and gas platforms with an imaging spectrometer by employing a method to capture the sun glint reflection from the water directly …

  • Ecosystem carbon balance in the Hawaiian Islands under different scenarios of future climate and land use change

    Open AccessPaul C Selmants, Benjamin Sleeter et al.ARTICLEEnvironmental Research Letters2021

    The State of Hawai'i passed legislation to be carbon neutral by 2045, a goal that will partly depend on carbon sequestration by terrestrial ecosystems. However, there is considerable uncertainty surrounding the future direction and magnitude of the land carbon sink in the Hawaiian Islands. We used the Land Use and Carbon Scenario Simulator (LUCAS), a spatially explicit stochastic simulation model that integrates landscape change and carbon gain-l…

  • Resistance of mound-building termites to anthropogenic land-use change

    Open AccessAndrew B Davies, Philip G Brodrick et al.ARTICLEEnvironmental Research Letters2020

    Humans pose a major threat to many species through land-use change in virtually every habitat. However, the extent of this threat is largely unknown for invertebrates due to challenges with investigating their distributions at large scales. This knowledge gap is particularly troublesome for soil macrofauna because of the critical roles many of these organisms perform as ecosystem engineers. We used a combination of high-resolution airborne Light …

  • Aboveground carbon emissions from gold mining in the Peruvian Amazon

    Open AccessOvidiu Csillik, Gregory P AsnerARTICLEEnvironmental Research Letters2020

    In the Peruvian Amazon, high biodiversity tropical forest is underlain by gold-enriched subsurface alluvium deposited from the Andes, which has generated a clash between short-term earnings for miners and long-term environmental damage. Tropical forests sequester important amounts of carbon, but deforestation and forest degradation continue to spread in Madre de Dios, releasing carbon to the atmosphere. Updated spatially explicit quantification o…

  • Sea surface temperature in coral reef restoration outcomes

    Open AccessShawna A Foo, Gregory P AsnerARTICLEEnvironmental Research Letters2020

    Successful restoration of coral reefs depends on the survival of outplanted species. Research shows that outplanting survival is mixed, with outplants often experiencing rapid mortality in response to various stressors. We used published results on outplant monitoring to investigate the role of sea surface temperature in the survival rates of corals. We find that the maximum temperature experienced at an outplanting site is very important in dete…

  • Titling indigenous communities protects forests in the Peruvian Amazon

    Open AccessAllen Blackman, Leonardo Corral et al.ARTICLEProceedings of the National…2017

    Significance Developing countries are increasingly granting local communities legal title to forests. Almost a third of forests in the global south are now managed by local communities, more than twice the share currently found in protected areas. However, we know little about the effects of titling on forest clearing and disturbance, which remain urgent problems. We use community-level longitudinal data derived from high-resolution satellite ima…

  • Deforestation risk due to commodity crop expansion in sub-Saharan Africa

    Open AccessElsa M Ordway, Gregory P Asner et al.ARTICLEEnvironmental Research Letters2017

    Rapid integration of global agricultural markets and subsequent cropland displacement in recent decades increased large-scale tropical deforestation in South America and Southeast Asia. Growing land scarcity and more stringent land use regulations in these regions could incentivize the offshoring of export-oriented commodity crops to sub-Saharan Africa (SSA). We assess the effects of domestic- and export-oriented agricultural expansion on defores…

  • Remotely sensed predictors of conifer tree mortality during severe drought

    Open AccessPhilip G Brodrick, Gregory P AsnerARTICLEEnvironmental Research Letters2017

    Widespread, drought-induced forest mortality has been documented on every forested continent over the last two decades, yet early pre-mortality indicators of tree death remain poorly understood. Remotely sensed physiological-based measures offer a means for large-scale analysis to understand and predict drought-induced mortality. Here, we use laser-guided imaging spectroscopy from multiple years of aerial surveys to assess the impact of sustained…

  • Accelerated losses of protected forests from gold mining in the Peruvian Amazon

    Open AccessGregory P Asner, Raul TupayachiARTICLEEnvironmental Research Letters2016

    Gold mining in Amazonia involves forest removal, soil excavation, and the use of liquid mercury, which together pose a major threat to biodiversity, water quality, forest carbon stocks, and human health. Within the global biodiversity hotspot of Madre de Dios, Peru, gold mining has continued despite numerous 2012 government decrees and enforcement actions against it. Mining is now also thought to have entered federally protected areas, but the ra…

  • Effects of long-term rainfall decline on the structure and functioning of Hawaiian forests

    Open AccessJomar M Barbosa, Gregory P AsnerARTICLEEnvironmental Research Letters2016

    Climate change is altering the dynamics of terrestrial vegetation, with consequences for the functioning of Earth’s biomes and the provisioning of ecosystem services. Changes in forest dynamics due to drought events or short-term drying trends have been described at different ecological scales, but few observational studies have determined the relative effects of short- and long-term precipitation trends (e.g. decade and century, respectively) on…

  • Branchfall dominates annual carbon flux across lowland Amazonian forests

    Open AccessDavid C Marvin, Gregory P AsnerARTICLEEnvironmental Research Letters2016

    Tropical forests play an important role in the global carbon cycle, but knowledge of interannual variation in the total tropical carbon flux and constituent carbon pools is highly uncertain. One such pool, branchfall, is an ecologically important dynamic with links to nutrient cycling, forest productivity, and drought. Identifying and quantifying branchfall over large areas would reveal the role of branchfall in carbon and nutrient cycling. Using…

What is alluded to, and yet unexplored, is the chang…

  • Elevated rates of gold mining in the Amazon revealed through high-resolution monitoring

    Open AccessGregory P Asner, William Llactayo et al.ARTICLEProceedings of the National…2013

    Significance Commodity gold prices increased substantially following the 2008 global financial crisis. Gold demand has fueled a massive increase in mining activity, some of which is centered in the Amazon basin. Western Amazonian forests of Peru have become an epicenter for mostly illegal gold mining, but the clandestine nature of mining activities has made monitoring and reporting of forest losses extremely challenging. We combined high-resoluti…
