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) -
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 ... -
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 ... -
Bahama Oriole Project team awarded NSF grant to offer more UMBC undergrads International Research Experiences
(UMBC, 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 ... -
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 ... -
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, ... -
Connectivity of wood thrush breeding, wintering, andmigration sites based on range-wide tracking
(Society for Conservation Biology, 2014-07-22)Many migratory animals are experiencing rapid population declines, but migration data withthe geographic scope and resolution to quantify the complex network of movements between breedingand nonbreeding regions are often ... -
Conservation Biology of the Critically Endangered Bahama Oriole: Estimating Current Population Size and Evaluating Threats
The Bahamas and adjacent Caribbean islands are home to eight island endemic orioles, half of which are Threatened or Near Threatened. The Bahama Oriole (Icterus northropi) is listed by IUCN as Critically Endangered. ... -
The Conservation Ideological State Apparatus
(Conservation & Society, 2018)This article considers Louis Althusser's theory of the ideological state apparatuses (ISAs) for advancing political ecology scholarship on the functioning of the state in violent environments. I reflect on a series of ... -
Creating Landscape-Scale Site Index Maps for the Southeastern US Is Possible with Airborne LiDAR and Landsat Imagery
(MDPI, 2019-03-06)Sustainable forest management is hugely dependent on high-quality estimates of forest site productivity, but it is challenging to generate productivity maps over large areas. We present a method for generating site index ... -
Cultivating Portlandia: A Mixed-Method Study of Residential Urban Agriculture in Portland, Oregon
(2014)Research Question: What is the scale and scope of residential urban agriculture (UA) in metro Portland? How does the practice of UA vary spatially? How do gardeners' motivations and practices vary along socioeconomic lines? -
Data colonialism through accumulation by dispossession: New metaphors for daily data
(Sage, 2015)In recent years, much has been written on ‘big data’ in both the popular and academic press. After the hubristic declaration of the “end of theory” more nuanced arguments have emerged, suggesting that increasingly pervasive ... -
Development Encounters in International Development Volunteerism in Guatemala: Quiet Encroachments in Global Street Politics
(Sage Journals, 2020-03-05)Neoliberal policies alter development funding, practice, and actors. One effect of this is an increase in untrained individuals from the Global North who travel to the Global South to take action against perceived needs. ...
