The objective of this study was to investigate the multiple uses and cognitive importance of edible weeds in Northeast Thailand. Research methods included focus group discussions and freelistings. A total of 43 weeds consumed as vegetable were reported, including economic, naturalized, agricultural and environmental weeds. The weedy vegetables varied considerably...
Background: Wild food plants are a critical component in the subsistence system of rice farmers in Northeast Thailand. One of the important characteristics of wild plant foods among farming households is that the main collection locations are increasingly from anthropogenic ecosystems such as agricultural areas rather than pristine ecosystems. This...
The success of restoration in attaining wildlife conservation goals can be strongly dependent on both site-scale and landscape-scale habitat characteristics, particularly for species with complex life cycles. Wetland management activities typically target plant communities, and bottom-up responses in higher trophic levels may be dependent on spatially explicit habitat use. We...
Sea turtles have historically been a primary resource for many of the coastal inhabitants of Bahia Magdalena, Baja California Sur, Mexico. Despite their endangered status and the implementation in 1990 of Mexican laws prohibiting the harvest of sea turtles, the demand for and the supply of these animals has persisted...
A one-dimensional (1D) hydrologic-hydraulic model for simulating dual drainage in urban areas is presented. It consists of four modules: (1) rainfall-runoff transformation, (2) 1D flow routing on a street network, (3) flow interception at street inlets, and (4) flow interaction between surface water on the streets and the underground storm-water...
Determining the mechanisms responsible for the success of invasive species is critical for
developing effective management strategies. Artificially draining managed wetlands to maintain natural
ephemeral conditions is a common practice in the Pacific Northwest and is assumed to kill invasive American
bullfrog (Lithobates catesbeianus) larvae, which typically overwinter in permanent...
"Marbled Murrelets (Brachyramphus marmoratus) are small diving seabirds who have the unique adaptation of flying inland to nest in large forest trees along the west coast of North America (see review in Marshall, 1988). The dual nature of their life history, as forest bird and as seabird, presents problems to...
Biological invasion potential can be strongly influenced by abiotic factors such as temperature, water availability, and solar radiation. Invasive species that possess phenotypically plastic traits can mediate impacts from these stressors, but may be unable to recognize and respond to dangerous levels in a novel environment. Understanding potential constraints on...
The goal of this study was to develop an understanding of the nature of wave loading on a wood-framed scale residential building model for a variety of building configurations and test conditions. Testing was performed on a 1/6th scale two-story wood-framed residential structure. The structure was impacted with waves and...
Black men who have sex with men (BMSM) experience among the highest rates of HIV infection in the United States. We conducted a community-based ethnography in New York City to identify the structural and environmental factors that influence BMSMs vulnerability to HIV and their engagement with HIV prevention services. Methods...
