Watershed models have become useful and necessary to evaluate impacts of conservation management practices on non-point source pollution (NPSP), as in situ studies at the watershed scale have inherent problems such as high costs due to their large scale and complex nature, private ownership of land, and results not timely enough to avoid negative consequences of current practices (Korfmacher, 2...
Most Phytophthora hybrids characterized to date have emerged from nurseries and managed landscapes, most likely generated as a consequence of biological invasions associated with the movement of living plants and germplasm for ornamental, horticultural and agricultural purposes. Presented here is evidence for natural hybridization among a group of five closely related indigenous clade 6 Phytoph...
Florida's coasts have been transformed over the past three decades as population growth and unprecedented demand for individual shore access to bays and estuaries led to the creation of residential canal developments. Thousands of miles of channels and basins were dredged as a by-product of this urbanization process. The navigable waterways that resulted are now being stressed by increasing boa...
Geographic information systems (GIS) are powerful tools for investigating the ecogeography of environmentally acquired infections. GIS technology was used to geocode and map cases of blastomycosis, by household, of human and dog residents of Vilas County, Wisconsin, USA. Human case households (n = 136) were from a comprehensive street address registry 1979--2001; human controls were 200 random-...
Outdoor residual sprays are among the most common methods for targeting pestiferous ants in urban pest management programs. If impervious surfaces such as concrete are treated with these insecticides, the active ingredients can be washed from the surface by rain or irrigation. As a result, residual sprays with fipronil and pyrethroids are found in urban waterways and aquatic sediments. Given th...
The shipping industry is moving towards quickly decarbonizing its assets. There also a growing demand for new urban transportation (passengers, building materials, and equipment) with zero-emission propulsion. Zero-emission propulsion available today sustainable transport. common size of inland navigation vessels offers the opportunity to implement innovative technologies earlier than seagoing ...
