Fisheries Research Report No. 158 - An Assessment Of The Blue Swimmer Crab Fishery In Geographe Bay, Lynda M. Bellchambers, K. D. Smith, D. Harris

Fisheries Research Reports

The study was undertaken to provide detailed information on blue swimmer crabs in Geographe Bay so that the recreational and commercial fishery issues could be addressed using more accurate data than was previously available. A ministerial decision that banned commercial fishing for blue swimmer crabs in Geographe Bay was made in January 2005 while this study was underway. The intention of this report was to provide a summary of information on crab stocks in the region, not to alter the current management arrangements. This report describes experimental sampling, commercial catch statistics, commercial catch monitoring and surveys of recreational fishers to …

On The Spatial Nature Of The Groundwater Pumping Externality, Nicholas Brozovic, David L. Sunding, David Zilberman

Daugherty Water for Food Global Institute: Faculty Publications

Most existing economic analyses of optimal groundwater management use single-cell aquifer models, which assume that an aquifer responds uniformly and instantly to ground- water pumping. This paper demonstrates how spatially explicit aquifer response equations from the water resources engineering literature may be embedded in a general economic framework. Calibration of our theoretical model to published economic studies of spe- cific aquifers demonstrates that, by averaging basin drawdown across the entire resource, existing studies generally understate the magnitude of the groundwater pumping external- ity relative to spatially explicit models. For the aquifers studied, the drawdown predicted by single- cell models may …

Fisheries Research Report No. 155 - Identification Of Western Australian Grey Nurse Shark Aggregation Sites., J. Chidlow, Daniel J. Gaughan, Rory Mcauley

Fisheries Research Reports

Final report to the Australian Government, Department of the Environment and Heritage

The first phase of this project involved a desktop study to broadly identify areas where Western Australian Grey Nurse Sharks potentially aggregate for further investigation with field surveys. These areas were identified from information obtained from commercial shark fishers, previously unpublished research data, as well as anecdotal reports of sightings or captures from recreational divers and fishers, professional dive stores, dive clubs and charter boat operators. A total of 25 survey areas were identified during the desktop study, 16 of which were in depths less than 30m and …

Invasive Species Definition Clarification And Guidance, Invasive Species Advisory Committee

National Invasive Species Council

Summary

Invasive species are those that are not native to the ecosystem under consideration and that cause or are likely to cause economic or environmental harm or harm to human, animal, or plant health. Plant and animal species under domestication or cultivation and under human control are not invasive species. Furthermore for policy purposes, to be considered invasive, the negative impacts caused by a non-native species will be deemed to outweigh the beneficial effects it provides. Finally, a non-native species might be considered invasive in one region but not in another. Whether or not a species is considered an invasive …

Fire History, Passerine Abundance, And Habitat On A North Dakota Drift Plain Prairie, Timothy J. Ludwick, Robert K. Murphy

The Prairie Naturalist

Prescribed fire is among key tools for restoring and managing prairies in the northern Great Plains, yet there are no published reports of its impacts on grassland passerine birds on native prairie in the Drift Plain, a major physiographic subregion. We examined relationships between prescribed fire history and abundance and habitat of breeding passerines in Drift Plain prairie at Des Lacs National Wildlife National Refuge in northwestern North Dakota. In 2003, we used point counts (n = 79 75 m radius plots) to survey bird abundance on 16 management units that had been prescribe-burned one to three times each …

Fisheries Research Report No. 153 - A 12-Month Survey Of Recreational Fishing In The Pilbara Region Of Western Australia During 1999-2000, P C. Williamson, Neil R. Sumner, B E. Malseed

Fisheries Research Reports

A 12-month creel survey of recreational boat-based and shore-based fishing in the Pilbara region (Onslow to Broome inclusive) of Western Australia was conducted between December 1999 and November 2000. During the survey 3,085 boat crews were interviewed at public boat ramps when they returned from their fishing trips. Patrols conducted along the coastline interviewed 73 groups of boat-based fishers and 569 groups of shore-based fishers at fishing locations and camp sites.

The total annual recreational fishing effort for the Pilbara region was estimated to be 201,000 fisher days (95%CI: 193,000 – 210,000). This comprised 109,000 fisher days by boats launched …

New Directions In Conservation For The National Wildlife Refuge System, Robert L. Fischman, Vicky J. Meretsky, James R. Karr, Daniel M. Ashe, Michael Scott, Reed F. Noss, Richard L. Schroeder

Articles by Maurer Faculty

The National Wildlife Refuge System Improvement Act of 1997 includes the nation’s broadest statutory commitment to ecosystem protection: to “ensure that the biological integrity, diversity, and environmental health of the system are maintained.” The act also directs the US Fish and Wildlife Service (FWS) to expand the scope of conservation monitoring, assessment, and management beyond refuge boundaries to encompass surrounding landscapes. The act thus gives the FWS a leadership role in developing research and management partnerships with other agencies, organizations, and neighboring landowners. Increasing research capacity and scientific expertise, and strengthening institutional resolve to limit activities that impede the attainment …

A Convective Line With Leading Stratiform Precipitation From Bamex, Brandom Storm, Matthew D. Parker, David P. Jorgensen

School of Natural Resources: Faculty Publications

On 31 May 2003, a front-fed convective line with leading stratiform precipitation (FFLS) was observed during the Bow Echo and Mesoscale Convective Vortex Experiment (BAMEX). The high-resolution BAMEX measurements provided one of the first opportunities to thoroughly observe the characteristics of an FFLS system. The 31 May system had an overturning updraft during its early stages, and produced leading stratiform precipitation. As the system matured, a jump updraft developed and the system began to produce trailing stratiform precipitation. It appears that this transition was facilitated by a local decrease in the low-level line-perpendicular vertical wind shear over time, as well …

Severe Convective Wind Environments, Evan L. Kuchera, Matthew D. Parker

School of Natural Resources: Faculty Publications

Nontornadic thunderstorm winds from long-lived, widespread convective windstorms can have a tremendous impact on human lives and property. To examine environments that support damaging wind producing convection, sounding parameters from Rapid Update Cycle model analyses (at 3-hourly intervals) from 2003 were compared with 7055 reports of damaging winds and 377 081 occurrences of lightning. Ground- relative wind velocity was the most effective at discriminating between damaging and nondamaging wind convective environments. Steep surface-based lapse rates (a traditional damaging wind parameter) gener- ally did not discriminate between damaging and nondamaging wind convective environments. Other pa- rameters, such as convective available potential …

Trend Identification In Twentieth-Century U.S. Snowfall: The Challenges, Kenneth E. Kunkel, Michael A. Palecki, Kenneth G. Hubbard, David A. Robinson, Kelly T. Redmond, David R. Easterling

School of Natural Resources: Faculty Publications

There is an increasing interest in examining long-term trends in measures of snow climatology. An examination of the U.S. daily snowfall records for 1900–2004 revealed numerous apparent inconsistencies. For example, long-term snowfall trends among neighboring lake-effect stations differ greatly from insignificant to +100% century -1.

Internal inconsistencies in the snow records, such as a lack of upward trends in maximum seasonal snow depth at stations with large upward trends in snowfall, point to inhomogeneities. Nationwide, the frequency of daily observations with a 10:1 snowfall-to-liquid-equivalent ratio declined from 30% in the 1930s to a current value of around 10%, a change …
