Cranes : their biology, husbandry, and conservation( Book )

5 editions published between 1996 and 1999 in English and held by 419 WorldCat member libraries worldwide

"Unbridled, mankind is unique in having the ability to erase the cranes, one or all, from our world. Ironically, it is also within the power of man to recognize the beauty and worth of something not our kin (or stated more correctly, to recognize our kinship to a dissimilar species), to recognize and revere. This book is dedicated to these lovely creatures, and to those persons living, remembered, and yet unborn who will continue the struggle to ensure a world rich with cranes. In the paragraphs that follow, we will cite some of those whose contributions were greatest in completing this volume and in supporting our husbandry effort s .Others will be mentioned in photo captions and text. How ver, this act (i.e., citing our fellow workers ) should not, in any way, diminish our awareness of, and appreciation for, the true inspiration for this volume, namely, the 15 species of cranes that grace our planet. This book is a celebration of the magnicence of these creatures and of man s efforts to ensure survival of each species. --From the introduction

Population biology of the Florida manatee by U.S. Dept. of the Interior. National Biological Service( Book )

7 editions published in 1995 in English and held by 292 WorldCat member libraries worldwide

The Florida manatee is a distinct subspecies of the West Indian manatee and one of the largest inshore mammals of the continent. Manatees are the only living North American representatives of the small mammalian Order Sirenia and are the only embodiment of the unique suite of biological features that define the distinctive adaptive syndrome fo the ordinal level of the taxonomic hierarchy
Agricultural practices, farm policy, and the conservation of biological diversity by Philip W Gerard( Book )

3 editions published in 1995 in English and held by 253 WorldCat member libraries worldwide

Long-term wildlife population declines are associated with changing agricultural practices. Cropland expansion, agricultural intensification, and national farm policies are all implicated in these declines. Social, economic, technological, and political factors determine where, what, and how a farmer produces crops and therefore his or her effect on wildlife habitat. Farmers are also influenced by Department of Agriculture programs, which therefore are indirectly implicated in wildlife population declines. Changes in the prairie and Great Plains agricultural landscape since the 1950's provide a clear example of the relation between federal agriculture policy, farmers' land-use practices, and the decline of grassland bird species. Early research indicates that the Conservation Reserve Program may help to slow or reverse wildlife losses, including those of several species listed as endangered. However, Conservation Reserve Program benefits to wildlife populations may vary considerably across the United States. Wildlife conservation in the agricultural landscape is limited by conflicting conservation objectives, the voluntary nature of federal agriculture programs, and the habitat requirements of many endangered vertebrate species. Biological conservation should be an explicit objective of agricultural conservation policy. The full potential of wildlife conservation within the context of farm conservation policy will require extensive collaboration between U.S. Fish and Wildlife Service and U.S. Department of Agriculture personnel and will only be realized if conservation policies are uncoupled from policies attempting to control agricultural commodities

A critical review of the aerial and ground surveys of breeding waterfowl in North America by Graham W Smith( Book )

3 editions published in 1995 in English and held by 248 WorldCat member libraries worldwide

The U.S. Fish and Wildlife Service and the Canadian Wildlife Service in cooperation with others have conducted an annual survey of breeding waterfowl throughout central Canada, the north-central United States, and Alaska since 1955. The area comprises more than 50 strata of habitats. Ducks are counted from aerial transects, and the counts are adjusted upward to account for birds that are not observed by aerial crews. These adjustments, called visibility correction factors, are developed from counts on the ground during which all waterfowl are assumed to have been detected. Counts on the ground are made of a subsample of the aerial survey. Visibility correction factors are calculated for each species and for each aerial crew. The total number of ducks by species and by strata is then calculated as the product of the observed density, the visibility correction factor, and the area of the strata

Silver hazards to fish, wildlife, and invertebrates : a synoptic review by Ronald Eisler( Book )

4 editions published in 1996 in English and held by 245 WorldCat member libraries worldwide

Ecological and toxicological aspects of silver (Ag) and silver salts in the environment are briefly summarized with an emphasis on natural resources. Elevated silver concentrations in biota occur in the vicinities of sewage outfalls, electroplating plants, mine waste sites, and silver-iodide seeded areas; in the United States, the photography industry is the major source of anthropogenic silver discharges into the biosphere. Silver and its compounds are not known to be mutagenic, teratogenic, or carcinogenic. Under normal routes of exposure, silver does not pose serious environmental health problems to humans at less than 50 ug total Ag/L drinking water or 10 ug total Ag/m3 air. Free silver ion, however, was lethal to representative species of sensitive aquatic plants, invertebrates, and teleosts at nominal water concentrations of 1.2 to 4.9 ug/L; sublethal effects were significant between 0.17 and 0.6 ug/L. Silver was harmful to poultry at concentrations as low as 1.8 mg total Ag/kg whole egg fresh weight by way of injection, 100 mg total Ag/L in drinking water, or 200 mg total Ag/kg in diets; sensitive mammals were adversely affected at total silver concentrations as low as 250 ug/L in drinking water, 6 mg/kg in diets, or 13.9 mg/kg whole body

Seasonal bathymetric distributions of 16 fishes in Lake Superior, 1958-75 by James H Selgeby( Book )

2 editions published in 1996 in English and held by 234 WorldCat member libraries worldwide

The bathymetric distributions of fishes in Lake Superior has not been studied on a lakewide scale. Knowledge about the bathymetric distributions will aid in designing fish sampling programs, estimating absolute abundances, and modeling energy flow in the lake. Seasonal bathymetric distributions were determined, by 10m depth intervals, for 16 fishes collected with bottom trawls and bottom-set gill nets within the upper 150m of Lake Superior during 1958-75. Bathymetric distributions in spring gill nets were similar to those in trawls, with some exceptions. Lake herring and kiyi were rarely caught in trawls. In summer, pygmy whitefish, shortjaw cisco, lake herring, kiyi, longnose sucker, burbot, ninespine stickleback, trout-perch, slimy sculpin, and spoonhead sculpin were at shallower depths than in spring, whereas rainbow smelt were found in deeper water; there was no change for the other species. In fall, shortjaw cisco was at shallower depths than in summer, whereas the remaining species were found deeper, except for lake whitefish and lake trout whose modal depths did not change. Distributions of lake trout and lake whitefish were also analyzed by age group. The shallow-water species exhibited little seasonal changes in bathymetric distributions, whereas the species that inhabited the middepths and deeper water generally moved shallower as the seasons progressed. Most of the more pronounced seasonal changes in bathymetric distribution were associated with spawning movements

Ecology of maritime forests of the southern Atlantic Coast : a community profile by Vincent J Bellis( Book )

4 editions published in 1995 in English and held by 225 WorldCat member libraries worldwide

Maritime forests dominated by broadleaved evergreen trees and shrubs occur in a discontinuous narrow band along the barrier islands and on the adjacent mainland from North Carolina to Florida. The flora and fauna of maritime forests typically consist of a distinctive subset of the regional biota that is particularly well adapted to survive the elevated salt content, limited availability of fresh water, soil erosion and dune migration, periodic seawater inundation, and wind damage associated with oceanic storms. Maritime forests cover the more stable portions of barrier islands and coastal dune ridges. They function as refugia for wildlife, provide storage capacity for groundwater, and help stabilize the soil. Recent recognition of the relatively greater physical stability of maritime forests compared to the beachfront has resulted in intensified urban development within them. Maritime forests across the range have been increasingly impaired by clearing for roads and parking lots and fragmented by subdivision development. Further development within maritime forests should minimize impairment of their critical biological and ecological functions. Maritime forest management should be directed toward reducing forest fragmentation and toward protecting their ecological integrity
Wetland use by waterbirds that winter in coastal Texas by U.S. Dept. of the Interior. National Biological Service( Book )

3 editions published in 1996 in English and held by 222 WorldCat member libraries worldwide

Wetland use and selection by species of waterbirds (shorebirds, wading birds, gulls, terns, grebes, cormorants, and pelicans) between the Rio Grande and Galveston Bay in coastal Texas were studied during September and November of 1991-92 and during January and March of 1992-93. Based on a stratified (by dominant land use) random sample of 64%.75-ha plots, 88 species of waterbirds using the wetlands were observed. Ranks of density and proportion of feeding birds indicated that cormorants and pelicans preferred wetlands with less than 30% vegetation. Gulls, terns, and skimmers preferred certain types of estuarine and lacustrine wetlands with less than 30% vegetation, especially estuarine subtidal rock bottom rubble types. Grebes and rails selectively used palustrine aquatic-bed rooted vascular and unconsolidated bottom mud wetland types. Herons, egrets, and bitterns preferred certain types of lacustrine and estuarine wetlands. Shorebirds used estuarine intertidal wetlands. Waterbird management should focus on 26 of the 82 wetland types that we prioritized in the coastal plains of Texas. Management should focus on protecting, enhancing, or restoring complexes of various wetland types, especially estuarine aquatic-bed and intertidal unconsolidated substrate types
