Identification Of Tire Leachate Toxicants And A Risk Assessment Of Water Quality Effects Using Tire Reefs In Canals, S. M. Nelson, G. Mueller, D. C. Hemphill, U.S. Bureau Of Reclamation

Publications (WR)

Cover is an important component of aquatic habitat and fisheries management. Fisheries biologists often try to improve habitats through the addition of natural and artificial material to improve cover diversity and complexity. Habitat-improvement programs range from submerging used Christmas trees to more complex programs using sophisticated artificial habitat modules. Used automobile tires have been employed in the large scale construction of reefs and fish attractors in marine environments and to a lesser extent in freshwater and have been recognized as a durable, inexpensive and long-lasting material which benefits fishery communities.

Recent studies by the U.S. Bureau of Reclamation have quantified …

Homosexual Copulations By Male Tree Swallows, Michael P. Lombardo, Ruth M. Bosman, Christine A. Faro, Stephen G. Houtteman, Timothy S. Kluisza

Peer Reviewed Publications

Homosexual courtship behavior in non-human animals is well known (Ford and Beach 1980) and occurs in a wide variety of taxa. However, homosexual copulations, especially between males, are less well known. In birds, males mounting other males have been observed in the colonially breeding Cattle Egret (Bubulcus ibis) (Fujioka and Yamagishi 1981) and Common Murre (Uria aalge) (Birkhead et al. 1985, Hatchwell 1988). Neither Fujioka and Yamagishi (1981) nor Birkhead et al. (1985) and Hatchwell (1988) reported whether cloacal contact occurred during their observations of male-male mountings. Here we describe homosexual copulations by male Tree Swallows …

TERRAPENE CAROLINA CAROLINA (Eastern Box Turtle). REPRODUCTION. Female Terrapene carolina containing oviductal eggs have been recorded in Virginia from 26 May to 25 July (Mitchell, in press. The Reptiles of Virginia. Smithsonian Inst. Press, Washington, D.C.). Other reports of reproduction in Terrapene (see list in Ernst and McBreen 1991. Cat. Amer. Amphib. Rept. 512.1-512.13) indicate that nesting occurs in late spring and early summer throughout its range.

Xenopus Laevis As A Model Organism, David C. Cannatella, Rafael O. De Sá

Biology Faculty Publications

Model organisms are often assumed to be representative of some more inclusive taxon of which the species is a part. This assumption leads to mistaken generalizations about the evolutionary and comparative significance of the data gathered. This paper reviews com? parative and evolutionary studies of Xenopus laevis and its relatives. Phylogenetic analysis of data from DNA sequences and morphology indicate that Xenopus is monophyletic and that Silurana is its sister group. The most basal lineages of Pipidae diverged prior to the breakup of Gondwana. The bizarre morphology of Xenopus is in part due to changes in the mode of meta? …

Review Of Recreational Gill, Haul And Cast Netting In Western Australia., F. B. Prokop

Fisheries Management Papers

In this paper the Recreational Netting Committee has addressed an extremely complex and controversial issue in a forthright manner. They have developed a set of management proposals which accommodates recreational netting while recognizing the concerns of non-netters and the general community. The Committee would like to stress that it considers this plan as a package. For example the Committee would be strongly opposed to the considerable operational restrictions contained under Section 5 if there were not a trade-off in terms of a fairer criteria for which estuaries are open as proposed in Section 6.2. Similarly, the Committee would not be …

Management Arrangements For The Southern Demersal Gillnet And Demersal Longline Fishery 1994/95 Season., Southern Demersal Gillnet And Demersal Longline Management Advisory Committee

Fisheries Management Papers

At its meeting of 7 April 1993 the Southern Demersal Gillnet and Demersal Longline Fishery Management Advisory Committee (hereafter called "the Committee) was advised of the Western Australian Fisheries Department's Research Division's concern over the status of shark stocks. All the data available indicate that whiskery sharks are severely over-exploited with stock levels declining by around 10% to 30% of original levels. Current levels of fishing effort are expected to cause the stock to decline further. Gummy sharks have high risk of over exploitation (stock has declined to 40% -50% of original levels. Dusty whaler stocks (bronze whaler) is uncertain …

Management Proposals For 1993/94 And 1994/95 Western Rock Lobster Season., Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The Rock Lobster Industry Advisory Committee (RLIAC) in reviewing management arrangements for the rock lobster fishery, were concerned with two principle objectives: 1. That the management measures adopted would arrest the ongoing decline in breeding stock and seek to re-establish the number of breeding female rock lobster to levels consistent with known historic safe levels in the fishery. 2. That the management arrangements adopted would properly take into account market requirements in order to maximise returns to fishermen from an appropriate level of catch.

Avian Hatching Asynchrony: Brood Classification Based On Discriminant Function Analysis Of Nestling Masses, Given Harper, Steven Juliano, Charles Thompson

Scholarship

Studies of hatching asynchrony in altricial birds have used several methods to determine if a brood hatches synchronously or asynchronously. The most commonly used methods include making frequent nest visits during the time of hatching and using nestling mass or other measures of size on a given day to estimate nestling age or to describe the extent of the size hierarchy within broods. We made daily nest visits to determine if House Wren (Troglodytes aedon) broods hatched synchronously or asynchronously, and then compared classification of these broods based on discriminant function analysis with that based on mass differences of nestlings. …

Xylosylation Is An Endoplasmic Reticulum To Golgi Event, Barbara Vertel, Linda Walters, Nina Flay, Ann Kearns, Nancy Schwartz

Biology and Environmental Science Faculty Publications

The subcellular site of xylosylation, the first carbohydrate modification of the core protein that initiates glycosaminoglycan chain synthesis, was characterized in situ. Methods were developed to combine electron microscopic (EM) autoradiography and the radiolabeling of semi-intact chondrocytes. In the accompanying paper, Kearns et al. (Kearns, A. E., Vertel, B. M., and Schwartz, N. B. (1993) J. Biol. Chem. 268, 11097-11104) presented biochemical and subcellular fractionation studies that utilized semi-intact chondrocytes and radiolabeled UDP sugars to overcome obstacles to the direct analysis of xylosylation. The results suggested that xylosylation begins in the endoplasmic reticulum (ER) and continues in the Golgi. …

The Fisheries Department of WA and the Recreational Fishing Advisory Committee (RFAC), which is the peak body representing recreational fishers in WA, have been very pleased with the response to the implementation of two year review of recreational fisheries. Fisheries, RFAC and the fishing community recognise that the two year review was the first step in the continually evolving process of management of recreational fisheries. Since the new bag and size limit regulations were introduced in December 1991, there have been many suggestions for refinement and improvement. This management paper includes the most common and best suggestions for future management. …

Fisheries Management Paper No 53 - Rock Lobster Industry Advisory Committee - Report To The Minister For Fisheries And Management Arrangements For 1992/93, Fisheries Department Of Western Australia

Fisheries Management Papers

The Minister for Fisheries announced the 1992/93 fishing season management arrangements for West Coast Rock Lobster Fishery on 11 August 1992. These arrangements arose as a result of the Minister's consideration of the Rock Lobster Industry Advisory Committee's recommendations outlined in Fisheries Management Paper no.46.

Following this announcement, on 28 August 1992, the Western Australian Fishing Industry Council Sub-Committee on rock lobster submitted a range of alternative management proposals.

The Rock Lobster Industry Advisory Committee (RLIAC) met in Perth on the 9 September 1992 at the request of the Minister for Fisheries to further examine and report on management arrangements.

Ribosomal Dna And The Phylogeny Of Frogs, David M. Hills, Loren K. Ammerman, Michael T. Dixon, Rafael O. De Sá

Biology Faculty Publications

Phylogenetic analysis of 1656 aligned sites in the 28S ribosomal RNA gene of frogs supports some of the recently recognized higher groups of anurans but provides counter-support for others. The 28S rDNA data support the monophyly of the recently recognized Pipanura (me- sobatrachians plus neobatrachians), which in turn indicates paraphyly of archaeobatrachians. Me- sobatrachians (pelobatoids plus pipoids), which are either considered paraphyletic or weakly sup- ported as monophyletic in morphological analyses, also receive support as a monophyletic group from the 28S rDNA data. Hyloidea (=Bufonoidea), which is widely recognized but lacks morphological support, receives some molecular support as being monophyletic. …

Phytoplankton Relationships To Water Quality In Lake Drummond And Two Drainage Ditches, Christine G. Phillips, Harold G. Marshall

Biological Sciences Faculty Publications

A twelve-month phytoplankton study was conducted in Lake Drummond and Washington and Jericho Ditches from December 1988 to November 1989. Four dominant phytoplankton groups were identified at these sites. These were the Bacillariophyceae, Cyanophyceae, Cryptophyceae and an autotrophic picoplankton component. Over the past 20 years there has been a decrease in the mean pH levels of Lake Drummond and the replacement of one its former major components, the Chlorophyceae, by the Cyanophyceae. Based on water quality analysis results and species diversity indices, Lake Drummond is classified as in an early eutrophic stage of development.

Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation

Publications (WR)

Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments. While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …
