20 years of change in tundra NDVI from coupled field and satellite observations
(IOP Publishing, 2023-08-17)In 2022 we resampled normalized difference vegetation index (NDVI) along a 100 m transect in tundra near Utqiagvik, AK that had been previously measured through the 2000–2002 growing seasons, providing an opportunity to ... -
The 2013 FLEX—US Airborne Campaign at the Parker Tract Loblolly Pine Plantation in North Carolina, USA
(MDPI, 2017-06-16)The first European Space Agency (ESA) and NASA collaboration in an airborne campaign to support ESA’s FLuorescence EXplorer (FLEX) mission was conducted in North Carolina, USA during September–October 2013 (FLEX-US 2013) ... -
A lidar-based approach to measure channel incision in headwater streams in an urbanizing landscape
(2018-01-01)Stream channel incision can occur following landscape disturbances commonly related to urbanization. A method was developed to map reach-scale incision from lidar-derived digital elevation models using topographic openness, ... -
A Nation of Neighborhoods: A Quantitative Understanding of US Neighborhoods and Metropolitan Areas
(2020-01-01)While pedestrian-oriented urban places have been identified as beneficial in a number of fields, including public health and climate change, there is a shortage of quantitative studies of such places covering large geographic ... -
Achieving Multiple Conservation Goals with Satellite-Based Monitoring and Alert Systems
(2023-01-01)Conservation early warning and alert systems (CEAS) provide substantial opportunities to improve awareness of global change and deliver time-sensitive information to users taking measures to avert the loss of ecosystems ... -
Advancing theory of community assembly in spatially structured environments: local vs regional processes in river networks
(University of Chicago Press, 2011-01-18) -
Agricultural Landscape Composition Linked with Acoustic Measures of Avian Diversity
(MDPI, 2020-05-10)Measuring, monitoring, and managing biodiversity across agricultural regions depends on methods that can combine high-resolution mapping of landscape patterns with local biodiversity observations. This study explores the ... -
An alternative view of ecological community thresholds and appropriate analyses for their detection: comment
(Ecological Society of America, 2011-10-01) -
Analysis of environmental migrants and their mental health in strengthening health systems
(F1000 Research, 2020-11-24)Background: It is predicted that by 2050 more than 250 million people will have to relocate as a result of climate-related change to their home environment. The existential threat posed by anthropogenic phenomena such as ... -
Annual variation in long-distance dispersal driven by breeding and non-breeding season climatic conditions in a migratory bird
(Nordic Society Oikos, 2014-11-25)Long‐distance dispersal is a fundamental process in ecology and evolution but the factors that influence these movements remain poorly understood in most species. We used stable hydrogen isotopes to quantify the rate and ... -
The Anthropocene as an Event, not an Epoch
(Wiley, 2022-03-09)Over the course of the last decade the concept of the Anthropocene has become widely established within and beyond the geoscientific literature but its boundaries remain undefined. Formal definition of the Anthropocene as ... -
Anthropogenic Biomes: 10,000 BCE to 2015 CE
(MDPI, 2020-04-25)Human populations and their use of land have reshaped landscapes for thousands of years, creating the anthropogenic biomes (anthromes) that now cover most of the terrestrial biosphere. Here we introduce the first global ... -
Antibiotic responsibility and agricultural publics: diverse stakeholder perceptions of antibiotic use in animal agriculture
(Springer Nature, 2023-05-01)This paper examines diverse perspectives around the concept of responsibility concerning antibiotic use in animal agriculture. Antibiotic use in agriculture has been identified as a source of antimicrobial resistance, one ... -
The application of metacommunity theory to the management of riverine ecosystems
(Wiley, 2021-08-16)River managers strive to use the best available science to sustain biodiversity and ecosystem function. To achieve this goal requires consideration of processes at different scales. Metacommunity theory describes how ... -
Applications of Geographic Analysis in Parole and Probation
(2001-08)The advent of community-based supervision in parole and probation agencies has led to a new need for detailed location information. Three staff members received intensive training in the application of GIS tools to data ... -
Applications using EO-1 hyperion AT-sensor and surface reflectance: comparisons and case studies
(IEEE, 2010-12-03)The NASA EO-1 Hyperion observations were utilized to derive at-sensor Top-of-atmosphere (TOA) and ATREM-corrected surface reflectance over three study sites of different land use types. Direct comparisons between TOA and ... -
Arctic Tundra Vegetation Functional Types Based on Photosynthetic Physiology and Optical Properties
(IEEE, 2013-04-24)Non-vascular plants (lichens and mosses) are significant components of tundra landscapes and may respond to climate change differently from vascular plants affecting ecosystem carbon balance. Remote sensing provides critical ... -
Assessing performance of ZCTA-level and Census Tract-level social and environmental risk factors in a model predicting hospital events
(Elsevier, 2023-06)Predictive analytics are used in primary care to efficiently direct health care resources to high-risk patients to prevent unnecessary health care utilization and improve health. Social determinants of health (SDOH) are ... -
Assessing the biogeographical and socio-ecological representativeness of the ILTER site network
The challenges posed by climate and land use change are increasingly complex, with rising and accelerating impacts on the global environmental system. Novel environmental and ecosystem research needs to properly interpret ... -
Assessment of Vegetation Stress Using Reflectance or Fluorescence Measurements
(Wiley, 2007-05-01)Current methods for large-scale vegetation monitoring rely on multispectral remote sensing, which has serious limitation for the detection of vegetation stress. To contribute to the establishment of a generalized spectral ...
