The Vaquita: Can It Survive?, Robert L. Brownell Jr.
United States Department of Commerce: Staff Publications
The vaquita (Spanish for "little cow"), or Gulf of California harbor porpoise (Phocoena sinus), has the most limited range of any marine cetacean and is probably the rarest. It has been caught incidentally in gill nets set commercially for totoaba (Totoaba macdonaldi), large fish that were over-exploited in the upper Gulf of California until they, too, were endangered. In 1975. the Mexican Government announced a total indefinite closure on fishing for totoaba, Between the time this porpoise was described as new to science (1958) and its listing by the U.S. Fish and Wildlife Service as Endangered …
Distribution, Abundance, And Biomass Of Freshwater Mussels (Bivalvia: Unionidae) In Lake St. Clair, Thomas F. Nalepa, Jeffrey M. Gauvin
Distribution, Abundance, And Biomass Of Freshwater Mussels (Bivalvia: Unionidae) In Lake St. Clair, Thomas F. Nalepa, Jeffrey M. Gauvin
United States Department of Commerce: Staff Publications
A mussel population survey was conducted in Lake St. Clair with divers using SCUBA to sample at 29 stations throughout the lake. Mean abundance was 2 m-2 and mean biomass was 4.4 g dry wt m-2. Of the 18 species collected, Lampsilis radiata siliquoidea was by far the most abundant, accounting for 45% of all individuals. The age-frequency distribution of L. r. siliquoidea was dominated by individuals between 9 and 12 years old. In contrast, the second most abundant species, Leptodea fragilis, showed yearly variation in recruitment with no apparent trends in year class strength. Annual …

Books & book chapters
The greenhouse effect is now an established scientific fact. Evidence published in the US and Australia in 1987 leaves little room for doubt. Carbon dioxide sent into the air whenever fossil fuels are burnt traps reflected heat from the Earth's surface - just as a greenhouse traps heat on a summer's day.
The uncertainties currently present in any prediction of future regional climate are very large. This paper presents a synopsis of current literature related to the future climate of Western Australia.

Vorliegender Beitrag gibt einen überblick über die floristische Durchforschung der MVR.
Erste Kenntnisse über die Flora der Mongolei stammen aus dem 18. Jh. und der ersten Hälfte des 19. Jh. (MESSERSCHMIDT, BUNGE, MAXIMOVICZ). In der zweiten Hälfte und am Ende des 19. Jh. erbrachten vor allem die Expeditionen der Russischen Geographischen Gesellschaft umfangreiches botanisches Material (POTANIN, KOZLOV). Auch andere Forscher führten ausgedehnte Sammelreisen durcn (KLEMENZ, PALIBIN, SAPOZNIKOV). Nach der mongolischen Revolution von 1921 wurden von sowjetischer Seite bereits in den 20er Jahren Sammelreisen durchgeführt. 1925 wurde die Mongolische Kommission der Akademie der Wissenschaften der UdSSR geschaffen, die weitere Expeditionen …

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded.

13.3.2. Initial Considerations For Sampling Wetland Invertebrates, Leigh H. Fredrickson, Frederic A. Reid
13.3.2. Initial Considerations For Sampling Wetland Invertebrates, Leigh H. Fredrickson, Frederic A. Reid
Waterfowl Management Handbook
As the importance of invertebrates to waterbird nutrition and detrital processing has become increasingly evident, the need for effective and efficient invertebrate sampling has grown. Identification of invertebrate responses to management requires sampling and selection of appropriate sampling equipment. Goals must be established according to qualitative or quantitative needs, organism characteristics, and wetland types. Management objectives often can be met by sampling specific invertebrates to index the effect of management rather than through long-term studies requiring large sample sizes and intensive effort. Certain wetland and invertebrate characteristics that should be considered when initiating invertebrate sampling are described below.

13.4.1. Considerations Of Community Characteristics For Sampling Vegetation, Leigh H. Fredrickson, Frederic A. Reid
Waterfowl Management Handbook
Wetland managers often monitor marsh vegetation to determine if management goals have been met and expenditures justified. Vegetation can be monitored using indices that identify plant composition, trends in vegetative changes, or rough estimates of food production. Development of vegetation sampling protocol requires careful assessment of management goals in relation to benefits received from sampling efforts. Assessing the results of manipulations has direct management implications, whereas detailed studies that emphasize plant life histories or basic ecological investigations have less direct value. Information on plant community characteristics that will enable managers to match sampling techniques with refuge needs and the constraints …
13.4.10. Control Of Willow And Cottonwood Seedlings In Herbaceous Wetlands, Leigh H. Fredrickson, Frederic A. Reid
13.4.10. Control Of Willow And Cottonwood Seedlings In Herbaceous Wetlands, Leigh H. Fredrickson, Frederic A. Reid
Waterfowl Management Handbook
Willow and cottonwood are common species in forested wetlands and occur throughout most riparian and floodplain habitats of North America. These woody species are especially common in early successional stands where seasonal flooding occurs regularly. Cottonwood and willow are often considered problem plants, because they rapidly invade wetlands dominated by herbaceous flora and can form dense, extensive stands. The shade created by these species eliminates herbaceous undergrowth, and once the sapling stage is reached, cottonwoods and willows are difficult to eradicate. Control of these species can be costly and varies considerably with latitude.

Water Quality 1986 - 1987 Hillsborough County, Florida, Hillsborough County Environmental Protection Commission
Reports
The Hillsborough County Environmental Protection Act charges the Environmental Protection commission with the function of establishing, operating and maintaining a continuous program for monitoring water pollution. A county-wide water quality surveillance network has been designed to enable the staff to determine compliance with the Act and to determine whether the level of water pollution is increasing or decreasing throughout the county.
These data, obtained during 1972-1987 may provide useful background for eventual development, revision _ and enforcement of regulations, standard effluent limitation plans, or programs established under the Federal Water Pollution Control Act of 1972.

13.2.1. Waterfowl Use Of Wetland Complexes, Leigh H. Fredrickson, Frederic A. Reid
13.2.1. Waterfowl Use Of Wetland Complexes, Leigh H. Fredrickson, Frederic A. Reid
Waterfowl Management Handbook
Waterfowl are a diverse group of birds that have widely divergent requirements for survival and recruitment. Whistling-ducks, geese, and swans (Anserinae) and ducks (Anatinae) have contrasting life history requirements.
Several goose populations have expanded greatly despite extensive continental wetland losses and degradation. Most expanding populations nest in arctic areas where modifications or disturbance of nesting habitats have been minimal. These grazers often find suitable migratory and wintering habitats in terrestrial or agricultural environments. In contrast, ducks are less terrestrial and populations are influenced more by wetland characteristics, such as quality, total area of wetland basins, and size and configuration of …

13.3.1. Invertebrate Response To Wetland Management, Leigh H. Fredrickson
Waterfowl Management Handbook
By gaining greater understanding and appreciation of wetland environments, managers have developed creative insights for waterfowl conservation. Among the most exciting new developments in the understanding of functional wetlands has been the recognition of the important roles of invertebrates in aquatic ecosystems. These roles include trophic linkage from primary production to secondary consumers such as waterfowl, packaging of specific nutritional components such as amino acids and micronutrients for vertebrate predators, and detrital processing of wetland organic material. Although specific invertebrate responses to various management techniques are not always predictable and may differ among invertebrate species, patterns related to water regimes, …
