Review Of Endangered Birds. Management Techniques For Preserving Threatened Species, Ed. Stanley A. Temple, Paul A. Johnsgard
Paul Johnsgard Collection
In 1977 an international symposium brought together scientists having expertise in the conservation and management of the world's endangered species of birds. The resulting publication includes 50 papers that were presented at the symposium, together with some concluding remarks. Although this is certainly an impressive assemblage of papers and topics, it should be noted that only about 40 species are mentioned in the proceedings, as compared with a total of 265 species and 140 subspecies worldwide that are currently believed to be threatened.
Redescription And Comparison Of A Highly Fossorial Mole, Domninoides Mimicus (Insectivora, Talpidae), From The Clarendonian, Patricia W. Freeman
Redescription And Comparison Of A Highly Fossorial Mole, Domninoides Mimicus (Insectivora, Talpidae), From The Clarendonian, Patricia W. Freeman
University of Nebraska State Museum: Mammalogy Papers
The holotype of the species, Domninoides mimicus, is based on one tooth. Described in the present report is material containing a practically complete dentition and many postcranial elements which definitely belong with the teeth. This species is closely related to Domninoides valentinensis described by Reed (1962), but some of the antemolars in valentinensis are misidentified. The tooth formulas for valentinensis and for mimicus are given. Development of the cingula on the upper and lower molars in mimicus is conspicuous. Because of similar features in the postcranial bones, the Clarendonian mole may be as fossorial as Scalopus, probably the …

The Life History And Ecology Of Ptilostomis Postica (Walker) (Trichoptera: Phryganeidae) In Greenbottom Swamp, Cabell County, West Virginia, Mary Beth Roush
Theses, Dissertations and Capstones
The life histoy and ecology of Ptilostomis postica (Walker) from Greenbottom swamp in Cabell County, West Virginia were investigated from December 1977 to December 1978, Length-frequency histograms indicate the life cycle is uriivoltine. Larvae achieved their greatest growth rate (75%) from fall to winter. Case length showed its greatest increase (70.3%) for this same period. There was high correlation between case length and body length in fall (r=0.72) and winter (r=0.87), however, a low correlation (r=0.18) was found in spring. The diet of the larvae changed from carnivorous in fall and winter to omnivorous in spring. Pupation began at the …
Proposed Environmental Impacts Of The Gallipolis Locks And Dam Replacement, Ohio River Mile 279.2, On The Benthic Macroinvertebrates And Fishes Of Flatfoot Creek, Mason County, West Virginia, William L. Cremeans Jr.
Proposed Environmental Impacts Of The Gallipolis Locks And Dam Replacement, Ohio River Mile 279.2, On The Benthic Macroinvertebrates And Fishes Of Flatfoot Creek, Mason County, West Virginia, William L. Cremeans Jr.
Theses, Dissertations and Capstones
The Gallipolis Locks and Dam at Ohio River Mile 279.2 is soon to be modified or replaced. Construction in the area will effect the lower portion of the small drainage basin (14.61 km) of Flatfoot Creek. Depending on the action taken, a large proportion of Flatfoot Creek and/or a tributary of Mud Run will have severe ecological alterations. For this reason, Flatfoot Creek was investigated for water quality, benthic macroinvertebrates, fish populations and the feeding requirements of the fishes.
A physio-chemical analysis was made of Flatfoot creek. With the exception of five parameters, the creek met guidelines set by state …
Macroinvertebrate Populations In The Upper Mississippi River, David R. Mcconville
Macroinvertebrate Populations In The Upper Mississippi River, David R. Mcconville
Journal of the Minnesota Academy of Science
The macroinvertebrate community of the Mississippi River near Monticell, Minnesota, was examined for 22 months. Quantitative bottom fauna information was obtained by use of concrete block artificial substrate sampling units. Representative organisms were obtained from seven (7) orders, 15 families and 35 genera of benthic macroinvertebrates. All taxa collected displayed definite seasonal trends. The Orders Trichoptera, Diptera, and Ephemeroptera were the most abundant groups collected, Trichoptera (Hydropsyche and Cheumatopsyche) were the dominant members of the benthic population in both numbers and biomass. Midges and blackflies were the dominant Diptera. Pseudocloeon, Stenonema, and Ephemerella were the most frequently collected mayflies.

Shovelnose Sturgeon (Scaphirhynchus Platorhynchus) In The Minnesota River, Paul Durkee, Brian Paulson, Robert Bellig
Journal of the Minnesota Academy of Science
The shovelnose sturgeon, Scaphirhyncus platorhyncus, according to Eddy and Underhill (1974) has not been reported from the Minnesota River for a number of years. Recently, Wilcox et. al. (1978) reported a single adult taken in 1974, and two others in 1976. Our survey of the fishes in the Minnesota River showed a substantial number of shovelnose sturgeon, at least in certain locations. Twenty specimens were taken in 42 gill net days. Other data obtained included food habits and age-length relationships. Food habits were determined through volumetric analysis of stomach contents, and ages were obtained by sectioning the marginal pectoral fin …
Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech
Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.
The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …

Fisheries Report No 33 - The Western Rock Lobster Fishery 1975 - 1976, G. R. Morgan, E H. Barker
Fisheries Research Reports
iTshe fishery for the western rock lobster Panultrus ecygnus one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. …

Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker
Fisheries Research Reports
The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.
Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …

Components Of Variance Associated With Service Sire For Milk Yield And Reproductive Traits, L. P. Johnson, L. Dale Van Vleck
Components Of Variance Associated With Service Sire For Milk Yield And Reproductive Traits, L. P. Johnson, L. Dale Van Vleck
Department of Animal Science: Faculty Publications
The association of service sire or sire of fetus with three milk yield traits and two reproductive intervals were investigated. Two procedures for estimation of variance components, Henderson's Method 1 and Method 3, were applied to a model of herd-year-season, sire of cow, and service sire. Analyses were for sire of calf born to initiate second lactation and service sire of the cow in second lactation. About 11,000 second lactation records on Holstein cows were available after editing for breeding and calving dates. Service sires and sires of cows were required to be in artificial insemination. Estimates by Method 1 …
