Thermal infrared remote sensing of water temperature in riverine landscapes Thermal infrared remote sensing of water temperature in riverine landscapes
Water temperature in riverine landscapes is an important regional indicator of water quality that is influenced by both ground- and surface-water inputs, and indirectly by land use in the surrounding watershed (Brown and Krygier, 1970; Beschta et al., 1987; Chen et al., 1998; Poole and Berman, 2001).Coldwater fishes such as salmon and trout are sensitive to elevated water temperature...

Variance components estimation for continuous and discrete data, with emphasis on cross-classified sampling designs Variance components estimation for continuous and discrete data, with emphasis on cross-classified sampling designs
Variance components may play multiple roles (cf. Cox and Solomon 2003). First, magnitudes and relative magnitudes of the variances of random factors may have important scientific and management value in their own right. For example, variation in levels of invasive vegetation among and within lakes may suggest causal agents that operate at both spatial scales – a finding that may be...

Viral hemorrhagic septicemia Viral hemorrhagic septicemia
Viral hemorrhagic septicemia (VHS) is one of the most important viral diseases of finfish worldwide. In the past, VHS was thought to affect mainly rainbow trout Oncorhynchus mykiss reared at freshwater facilities in Western Europe where it was known by various names including Egtved disease and infectious kidney swelling and liver degeneration (Wolf 1988). Today, VHS is known as an...

Volcanoes: observations and impact Volcanoes: observations and impact
Volcanoes are critical geologic hazards that challenge our ability to make long-term forecasts of their eruptive behaviors. They also have direct and indirect impacts on human lives and society. As is the case with many geologic phenomena, the time scales over which volcanoes evolve greatly exceed that of a human lifetime. On the other hand, the time scale over which a volcano can move...

Wildlife forestry Wildlife forestry
Wildlife forestry is management of forest resources, within sites and across landscapes, to provide sustainable, desirable habitat conditions for all forest-dependent (silvicolous) fauna while concurrently yielding economically viable, quality timber products. In practice, however, management decisions associated with wildlife forestry often reflect a desire to provide suitable habitat...

Occurrence and distribution of Asian carps in Louisiana Occurrence and distribution of Asian carps in Louisiana
In the 1970s, commercial fishers reported sightings of grass carp Ctenopharyngodon idella in large rivers and associated backwaters of Louisiana; the first specimen in Louisiana Department of Wildlife and Fisheries' fishery independent sampling was recorded in 1976. Beginning in the early 1980s, commercial fishers noted increasing populations of bighead carp Hypophthalmichthys nobilis...

Hyperspectral remote sensing of wetland vegetation Hyperspectral remote sensing of wetland vegetation
Wetlands proportionally exert a higher influence on biogeochemical fluxes among the land, the atmosphere, and hydrologic systems than their 1% worldwide occurrence suggests [1]. Although their frequency of occurrence is low and their importance is high, wetlands continue to face high detrimental pressures from natural and human-induced forces [2]. Remote sensing offers the single best...

DDT, DDD, and DDE in birds DDT, DDD, and DDE in birds
This chapter summarizes residue levels of dichlorodiphenyltrichloroethane (DDT), DDD, and DDE three compounds in birds that are diagnostic for or are associated with mortality and important sublethal effects and suggests improvements in design of contemporary field studies that will result in maximum usefulness in interpreting residue data. Heath et al. first documented eggshell thinning...

Managing white-tailed deer: Eastern North America Managing white-tailed deer: Eastern North America
The ability of the white-tailed deer to adapt to and thrive in a wide variety of habitats requires different approaches to managing this species. Variation in both the population dynamics of the species and in the social and political factors that inuence how humans value white-tailed deer also necessitate different approaches. Consequently, providing an overview of the management of...
