Benthic Biological Monitoring Program Of The Elizabeth River Watershed (1999), Daniel M. Dauer

Elizabeth River Reports

Executive Summary

A study of the macrobenthic communities of the Elizabeth River watershed was conducted in summer 1999. The three objectives of the Benthic Biological Monitoring Program of the Elizabeth River watershed are: (1) To characterize the health of regional areas of the tidal waters of the Elizabeth River watershed Chesapeake Bay as indicated by the structure of the benthic communities. These characterizations are based upon application of benthic restoration goals and the Benthic Index of Biotic Integrity (BIBI) developed for the Chesapeake Bay to five primary strata - the Mainstem of the river, the Lafayette River, the Southern Branch, …


Effects Of Elevated Atmospheric Co2 On Root Growth, Turnover And Decomposition In A Scrub Oak Ecosystem, John Joseph Dilustro Jul 2000

Effects Of Elevated Atmospheric Co2 On Root Growth, Turnover And Decomposition In A Scrub Oak Ecosystem, John Joseph Dilustro

Biological Sciences Theses & Dissertations

Atmospheric carbon dioxide levels are increasing and predicted to double this century. The implications of this rise on vegetation structure and function are not well understood. Measurement of root growth response to elevated atmospheric carbon dioxide is critical to understanding soil carbon input. I investigated the effects of elevated carbon dioxide on fine root growth and decomposition using open top chambers with both ambient and elevated (700 PPM) CO2 treatments in an oak-palmetto scrub ecosystem at Kennedy Space Center, Florida. Minirhizotron tubes were installed in each elevated and control chamber to allow observation of roots. Each tube was sampled …


Degradation In The Brockman River And Ellen Brook Catchments, Western Australia, Brian Lloyd Jul 2000

Degradation In The Brockman River And Ellen Brook Catchments, Western Australia, Brian Lloyd

Natural resources published reports

An eight day survey of degradation in the Ellen Brook and Brockman River catchments revealed several areas of concern. Key concerns are:

Erosion and sedimentation

Various forms of erosion were observed during the survey that would cumulatively have an effect on the quality of both the Ellen Brook and the Brockman Rivers, and ultimately the Swan River. Erosion resulted from many situations including landholder management, subdivision design and infrastructure maintenance. Raising awareness as to consequences of erosion and sedimentation, along with remedial techniques and best management practices is recommended for the various levels of stakeholders.

Eutrophication has been established …


Conservation Conundrum, Robert L. Brownell Jr., Barbara E. Curry, Peter Daszak, Andrew A. Cunningham, Alex D. Hyatt Jun 2000

Conservation Conundrum, Robert L. Brownell Jr., Barbara E. Curry, Peter Daszak, Andrew A. Cunningham, Alex D. Hyatt

United States Department of Commerce: Staff Publications

P. Daszak, A. A. Cunningham, and A. D. Hyatt present a convincing argument in their Review "Emerging infectious diseases of wildlife-threats to biodiversity and human health" (Science's Compass, 21 Jan., p. 443) that emerging infectious diseases (EIDs) pose a risk to wildlife, and they suggest that EIDs most often result from a change in the ecology of the pathogen or the host (or both). A situation they did not mention is that in some cases, the protection of threatened species can increase the risk of an EID outbreak by allowing a close association between wildlife and domestic animals where one …


Digestibility, Nitrogen Excretion, And Mean Retention Time By North American Porcupines (Erethizon Dorsatum) Consuming Natural Forages, Laura A. Felicetti, Lisa A. Shipley, Gary W. Witmer, Charles T. Robbins Jun 2000

Digestibility, Nitrogen Excretion, And Mean Retention Time By North American Porcupines (Erethizon Dorsatum) Consuming Natural Forages, Laura A. Felicetti, Lisa A. Shipley, Gary W. Witmer, Charles T. Robbins

United States Department of Agriculture Wildlife Services: Staff Publications

North American porcupines (Erethizon dorsatum) subsist predominantly on low-protein, high-fiber, high-tannin diets. Therefore, we measured the porcupine's ability to digest dry matter, fiber, and protein by conducting digestion trials on eight natural forages and one pelleted ration varying in concentration of fiber, nitrogen, and tannins. On these diets, dry matter intake ranged from 5 to 234 g/kg 0.75/d and dry matter digestibility ranged from 62% to 96%. Porcupines digested highly lignified fiber better than many large hindgut fermenters and ruminants. The porcupine's ability to digest fiber may be explained, in part, by their lengthy mean retention time …

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman Jun 2000

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …


A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group Jun 2000

A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group

Fisheries Management Papers

The West Coast Region between Kalbarri and Augusta offers a wide range of recreational fishing opportunities.The West Coast Region also receives more fishing pressure than any other, with an estimated 380 000 anglers fishing each year. Already, the signs of a fishery under pressure are showing. Catch rates of dhufish around inshore reef systems such as the Three-mile are a far cry from the 1950s and 60s when people beachlaunched wooden dinghies to fish the inshore waters for these highly prized fish. Increasing pressure on stocks has led to growing community concerns that the future quality of recreational fishing is …


Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia. Jun 2000

Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.

Fisheries Management Papers

Land supply and land cost for aquaculture may become a limiting factor in the foreseeable future. At present, adequate appropriately zoned land is available at reasonable cost. The most prospective land for aquaculture in or near Esperance is where suitable zoned land occurs over saline ground water aquifers or adjacent to the coast. Careful site selection would be necessary to ensure water supply, waste water disposal, services and operational space can be achieved at reasonable cost.

Airflow Characteristics Of Commonly Used Temperature Radiation Shields*, X. Lin, Kenneth G. Hubbard, George E. Meyer May 2000

Airflow Characteristics Of Commonly Used Temperature Radiation Shields*, X. Lin, Kenneth G. Hubbard, George E. Meyer

School of Natural Resources: Faculty Publications

The air temperature radiation shield is a key component in air temperature measurement in weather station networks; however, it is widely recognized that significant errors in the measured air temperature exist due to insufficient airflow past the air temperature sensor housed inside the shield. During the last several decades, the U.S. National Weather Service has employed a number of different shields in air temperature measurements. This paper focuses on the airflow characteristics inside air temperature shields including the Maximum–Minimum Temperature System (MMTS), the Gill shields, and the Cotton Region Shelter (CRS).

Average airspeed profiles and airflow efficiency inside the shields …


Lethal Control Of Piscivorous Birds At Aquaculture Facilities In The Northeast United States: Effects On Populations, Bradley F. Blackwell, Richard A. Dolbeer, Laura A. Tyson May 2000

Lethal Control Of Piscivorous Birds At Aquaculture Facilities In The Northeast United States: Effects On Populations, Bradley F. Blackwell, Richard A. Dolbeer, Laura A. Tyson

United States Department of Agriculture Wildlife Services: Staff Publications

Predation by piscivorous birds is considered a substantial threat to the aquaculture industry. However, lethal control of birds at aquaculture facilities has raised concerns about the effects on the distribution and abundance of populations of the species killed. We examined the relationship between numbers of piscivorous birds reported killed under U.S. Fish and Wildlife Service (USFWS) permits at aquaculture facilities in New York, New Jersey, and Pennsylvania and species population trends within the respective states. The USFWS issued 26 permits to 9 facilities from 1985 through September 1997. Eight species appeared on permits, but only six species were reported killed: …


Extralimital Records Of The Mexican Free-Tailed Bat (Tadarida Brasilensis Mexicana) In The Central United States And Their Biological Significance, Hugh H. Genoways, Patricia W. Freeman, Cary Grell May 2000

Extralimital Records Of The Mexican Free-Tailed Bat (Tadarida Brasilensis Mexicana) In The Central United States And Their Biological Significance, Hugh H. Genoways, Patricia W. Freeman, Cary Grell

School of Natural Resources: Faculty Publications

Two new records of Tadarida brasiliensis mexicana are reported from Nebraska. The literature records of this taxon from the central United States are summarized. In this region of North America, these bats occupy a “natal range” where the species carries on regular reproductive activities and the populations are relatively stable, including California, Arizona, New Mexico, Texas, and Oklahoma. To the north of the natal range of T. b. mexicana is a “pioneering zone” where, under favorable conditions, the species is capable of reproducing and conducting its normal activities. The pioneering zone of the Mexican free-tailed bat includes Barber and Comanche …


Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman May 2000

Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman

School of Natural Resources: Faculty Publications

New distributional records are presented for 20 species of mammals in Nebraska. The majority of these records appear to represent changes in geographic distribution rather than just better sampling in poorly known areas. One group of mammals, including the opossum, northern myotis, evening bat, red bat, woodchuck, white-footed mouse, and gray fox, is expanding westward, probably in response to increasing woodlands along river systems. Another group, including the meadow vole, masked shrew, and least weasel, is expanding southward, possibly in response to new prey species and changing microclimates. The eastern woodrat appears to be expanding northward in eastern Nebraska. The …
