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 and silver c

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 source of ti

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 and assoc

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 white-tailed

Using regional-scale pre- and post Hurricane Katrina lidar for monitoring and modeling: Chapter 30
Hurricane Katrina was one of the largest natural disasters in U.S. history. Due to the sheer
size of the affected areas, an unprecedented regional analysis at very high resolution and
accuracy was needed to properly quantify and understand the effects of the hurricane and
the storm tide. Many disparate sources of lidar data were acquired and processed for
varying environmental reasons by pre- and

The Hydrogeology of the San Juan Mountains Chapter 5
Knowledge of the occurrence, storage, and flow of groundwater in mountainous regions is limited by the lack of integrated data from wells, streams, springs, and climate. In his comprehensive treatment of the hydrogeology of the San Luis Valley, Huntley (1979) hypothesized that the underlying, fractured volcanic bedrock of the San Juan Mountains has relatively high bulk permeability and a regional-

Utah's geologic and geomorphic analogs to Mars—An overview for planetary exploration
Utah offers spectacular geologic features and valuable analog environments and processes for Mars studies. Horizontal strata of the Colorado Plateau are analogous to Mars because the overprint of plate tectonics is minimal, yet the effects of strong ground motion from earthquakes or impacts are preserved in the sedimentary record. The close proximity of analog environments and lack of vegetative c

Measurement and modeling of unsaturated hydraulic conductivity
The unsaturated zone plays an extremely important hydrologic role that influences water quality and quantity, ecosystem function and health, the connection between atmospheric and terrestrial processes, nutrient cycling, soil development, and natural hazards such as flooding and landslides. Unsaturated hydraulic conductivity is one of the main properties considered to govern flow; however it is ve
