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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
Bahama Oriole Project team awarded NSF grant to offer more UMBC undergrads International Research Experiences
(UMBC News, 2018-11-06)UMBC is recognized as a national leader in undergraduate teaching, in part because the university connects so many students with meaningful research opportunities. Now, a new $300,000 NSF International Research Experiences ... -
Beyond the Screen: Uneven Geographies, Digital Labour, and the City of Cognitive-Cultural Capitalism
(tripleC: Communication, Capitalism & Critique. Journal for a Global Sustainable Information Society, 2017)In this paper, we demonstrate that an examination of the socio-environmental impacts of digital Information and Communication Technologies (ICTs) remains a fruitless enterprise without “materializing” digital labour. We ... -
Biodiversity and Plant Litter Decomposition in Streams
(Springer Nature, 2021-07-01)The main factors influencing litter decomposition in streams are substrate quality, metazoan feeding, microbial activity and environmental context. However, the biodiversity of both resources (litter) and consumers (mostly ... -
Biophysical and Socioeconomic Factors Associated with Forest Transitions at Multiple Spatial and Temporal Scales
(Resilience Alliance, 2011)Forest transitions (FT) occur when socioeconomic development leads to a shift from net deforestation to reforestation; these dynamics have been observed in multiple countries across the globe, including the island of Puerto ... -
Calculating Varying Scales of Clustering Among Locations
(U.S. Department of Housing and Urban Development, 2018)The Nearest Neighbor Index (NNI) is a spatial statistic that detects geographical patterns of clustered or dispersed event locations. Unless the locations are randomly distributed, the distances of either clustered or ... -
Challenging claims in the study of migratory birds and climate change
(Cambridge Philosophical Society, 2011-04-13)Recent shifts in phenology in response to climate change are well established but often poorly understood. Many animals integrate climate change across a spatially and temporally dispersed annual life cycle, and effects ... -
Changes in riparian vegetation buffers in response to development in three Oregon cities
Riparian vegetation buffer loss was investigated for three cities with contrasting local regulatory controls in urbanizing northwest Oregon. The cities examined were Hillsboro, Oregon City and Portland, all having experienced ... -
Coastal urbanization and the integrity of estuarine waterbird communities: Threshold responses and the importance of scale
(Elsevier B.V., 2008-10-10)Estuarine ecosystems are becoming increasingly altered by the concentration of human populations near the coastline, however a robust indicator of this change is lacking. We developed an index of waterbird community integrity ... -
Combining and aggregating environmental data for status and trend assessments: challenges and approaches
(Springer, 2015)Increasingly, natural resource management agencies and nongovernmental organizations are sharing monitoring data across geographic and jurisdictional boundaries. Doing so improves their abilities to assess local-, regional-, ... -
A community-engaged approach to transdisciplinary doctoral training in urban ecosystem services
(Springer Nature Switzerland AG., 2020-02-27)Community-based projects with inclusive stakeholder engagement are increasingly important to achieve robust outcomes in the science and management of ‘wicked’ urban ecosystem service challenges. We summarize lessons learned ... -
COMSOL Modeling of Groundwater Flow and Contaminant Transport in Two-Dimensional Geometries With Heterogeneities
(2011)The Delmarva Peninsula is located on the East Coast of the United States, between the Chesapeake Bay and Atlantic Ocean. Industrial farming in the Delmarva Peninsula leads to levels of nutrients, in particular nitrogen, ... -
Conceptual Links between Landscape Diversity and Diet Diversity: A Roadmap for Transdisciplinary Research
(Oxford Academic, 2020-06-24)Malnutrition linked to poor quality diets affects at least 2 billion people. Forests, as well as agricultural systems linked to trees, are key sources of dietary diversity in rural settings. In the present article, we ...
