Aspects and implications of bear reintroduction: Chapter 6 Aspects and implications of bear reintroduction: Chapter 6
Bear reintroduction has been practiced worldwide with varying degrees of success. Homing is a significant issue for American black bears, Ursus americanus, and winter-release techniques of females with cubs have been successfully used to improve settling rates and survival. Reintroduction success for all bear species appears to be positively correlated with translocation distance, and...

Organic compounds used in animal husbandry: Chapter 13 Organic compounds used in animal husbandry: Chapter 13
Although in general, the same drugs are used by humans as for animal husbandry, some compounds are unique to CAFOs. In raising and fattening steers, anabolic steroids are widely used in the US. In the cattle industry, large use is made of the acaricides, avermectins, and the cypermethrins as well as juvenile growth hormone inhibitor for fly and tick control that could affect soil fauna...

Three-dimensional movement of silver-phase American eels in the forebay of a small hydroelectric facility Three-dimensional movement of silver-phase American eels in the forebay of a small hydroelectric facility
Declines in the population of the American eel, Anguilla rostrata, along the northwestern Atlantic have stimulated resource managers to consider the impact of hydroelectric facilities on silver-phase eels as they migrate downstream to the sea. During the fall of 2002, we investigated the movement of migrant eels passing downstream of a small hydroelectric facility on the Connecticut...

Volcano monitoring Volcano monitoring
Volcanoes are not randomly distributed over the Earth's surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea where they form long mountain ranges. More than half of the world's active volcanoes above sea level encircle the Pacific Ocean (see Fig. 1). The concept of plate tectonics explains the locations of volcanoes and their relationship to...

Nutrient dynamics Nutrient dynamics
This chapter focuses on the variability and trends in chemical concentrations and fluxes at Mirror Lake during the period 1981–2000. It examines the water and chemical budgets of Mirror Lake to identify and understand better long-term trends in the chemical characteristics of the lake. It also identifies the causes of changes in nutrient concentrations and examines the contribution of...

Comparison of groundwater flow in Southern California coastal aquifers Comparison of groundwater flow in Southern California coastal aquifers
Development of the coastal aquifer systems of Southern California has resulted in overdraft, changes in streamflow, seawater intrusion, land subsidence, increased vertical flow between aquifers, and a redirection of regional flow toward pumping centers. These water-management challenges can be more effectively addressed by incorporating new understanding of the geologic, hydrologic, and

Aeromicrobiology/air quality Aeromicrobiology/air quality
The most prevalent microorganisms, viruses, bacteria, and fungi, are introduced into the atmosphere from many anthropogenic sources such as agricultural, industrial and urban activities, termed microbial air pollution (MAP), and natural sources. These include soil, vegetation, and ocean surfaces that have been disturbed by atmospheric turbulence. The airborne concentrations range from...

Optical satellite data volcano monitoring: a multi-sensor rapid response system Optical satellite data volcano monitoring: a multi-sensor rapid response system
In this chapter, the use of satellite remote sensing to monitor active geological processes is described. Specifically, threats posed by volcanic eruptions are briefly outlined, and essential monitoring requirements are discussed. As an application example, a collaborative, multi-agency operational volcano monitoring system in the north Pacific is highlighted with a focus on the 2007...
