The Neda Iron Ore Of Southeastern Wisconsin, William K. Kean

Field Station Bulletins

The Neda Iron Mine, located between Iron Ridge and MayviTie, Wisconsin, is a property owned by the University of Wisconsin-Milwaukee and managed by the UWM Field Station. The site today is a rather unobtrusive ridge of resistant dolomite, not dissimilar to a number of other resistant ridges which mark the presence of the Silurian dolomite in eastern Wisconsin. This dolomite is essentially the same rock formation which dips down under the state of Michigan and reemerges in western New York to form Niagara Falls. Beneath this resistant dolomite, is a thin surface exposure of red iron ore, known as the …

Daily Organization Of Vocalizations Of Forest-Edge Birds In Wisconsin, James W. Popp, Millicent S. Ficken, Robert W. Ficken

Field Station Bulletins

The daily patterning of vocalizations was determined for 15 species of forest-edge birds at the UWM Field Station. Species that were predominately callers (gave few songs) had very erratic patterns of vocalizations. Species that were primarily singers had distinct morning peaks in singing ("dawn chorus") and, for most species, smaller evening peaks. Some of the singers also had small mid-afternoon peaks when the overall singing rates were low. With the exception of the Field Sparrow, which had a peak before most other species, and the towhee, which had a peak after most other species, there was little interspecific variation in …

Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.

Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Eulimdana rauschorum n. sp. is described from southern black-backed gulls, Larus dominicanus Lichtenstein in Antarctica. The species is most similar to Eulimdana lari (Yamaguti, 1935) from Charadriiformes in the Holarctic. Males have spicules equal in length that are asymmetric in structure distally. There are 4-5 and 3-5 caudal papillae in rows to the right and left of the anus, and two small genital papillae at the posterolateral margin of the anus. Females have a variable number of prominent caudal papillae and large microfilariae (365 μm in length). The morphological similarities and host distribution of E. rauschorum and E. lari suggest …

Effects Of Pituitary Stalk-Transection And Type Of Barrier On Pituitary And Luteal Function During The Estrous Cycle Of The Ewe, David S. Mallory, C. M. Gust, R. A. Dailey

Biological Sciences Faculty Research

Effects of pituitary stalk-transection on plasma concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH) prolactin (PRL) and progesterone were investigated during the estrous cycle of ewes. Pituitary stalk (SS) or sham (SH) transection was performed on day 1 (estrus = day 0) of the estrous cycle. A Teflon or Silastic barrier was placed between the cut ends of the stalk to prevent reorganization of the portal vasculature. Immediately following surgery, pulsatile administration of gonadotropin releasing hormone (GnRH, 200 ng/hr) or .9% NaCl was initiated and continued for the duration of the experiment. Estradiol benzoate (EB, 50 μg im) …

Cardiac Correlates Of Individual Recognition In The Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee to recognize individuals depicted in photographs was evaluated through the use of heart rate measures. Heart rate was recorded before and during photographic projections of human caregivers, familiar individuals, strangers, and blank control slides. In the absence of explicit training or reinforcement, the chimpanzee displayed a differential pattern of heart rate response to the stimulus categories. Although heart rate responses to all stimuli were predominantly deceleratory, the photographs of caregivers yielded consistently larger responses than other stimuli. Results indicate that the chimpanzee is able to recognize individual humans from novel photographic representations and that heart …

Whooping Cranes In Blaine County, Wayne J. Mollhoff

Nebraska Bird Review

On 7 April 1986 John Manning, of Norfolk, and I observed a pair of Whooping Cranes (Grus americana) in southeastern Blaine County, about 20 miles west of Taylor. I was notified by a local rancher, who found them while feeding his cattle that morning. John and I were guided to where the birds were feeding in a field. We observed them from about 1400 to 1500 hours as they fed leisurely. About 1500 hours they took off and flew out of sight, heading toward the Middle Loup River. They were found again in the same field about 1745 …

Habitat Selection And Movement Patterns In Sandhills Rodents, Cliff A. Lemen, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Using fluorescent pigments, we were able to gather accurate information about the use of habitat and movement patterns of small nocturnal rodents. Use of habitat is strongly affected by the patchiness of vegetation of the sandhills. Microtus ochrogaster occupies the dense grass, Dipodomys ordii occupies the open sandy area, and Perognathus hispidus and P. flavescens occupy a mixed grass-forb zone. Advantages of the fluorescent method over more traditional methods of determining habitat use are presented. There are significant differences in the trails of species at the fine 10-cm scale, but these differences disappear at a larger 3-m scale. The significance …

Factors Influencing Best Annual Racing Time In Finnish Horses, M. Ojala, L. Dale Van Vleck, R. L. Quaas

Department of Animal Science: Faculty Publications

The fixed effects of year of race, season of race, sex, method of start, annual number of starts, length of race and racetrack were evaluated on best annual racing time in Finnish Horses. Data included 1,378 records for 554 horses by 206 sires. Five models were assumed within the age groups from 3 to 6 yr. The annual number of starts, method of start and season of race effects were interrelated. An increase in number of starts was associated with considerable improvement in a horse's best annual racing time. Records should not, however, be adjusted for effect of annual number …

Study Of A Small Mammal Population In Bowling Green, Kentucky, Richard Cambron

Masters Theses & Specialist Projects

The small mammal population of a restricted study area was live-trapped on the University farm at Western Kentucky University from November 1984 through November 1985. A total of 1800 trap-nights yielded 81 different individuals representing five species. Members of the genera Peromyscus and Microtus were the dominant individuals representing over 90% of the total. Also caught were Mus musculus and Blarina brevicauda. The members of the two major genera were examined for population size and dynamics. In addition, a statistical analysis was carried out on the randomness of the location of the home ranges. This analysis gave evidence that …

Brook Trout Enhancement Through Rainbow Trout Removal By Electroshocking In The Great Smoky Mountains National Park, Jeanne Dyanne Riley

Masters Theses

Brook trout ( Salvelinus fontinalis) populations have declined in the Great Smoky Mountains National Park since the early 1900's. The continuing range loss of the Parks' only native trout species has been attributed mainly to the introduced rainbow trout ( Salmo gairdneri ) . Past studies have indicated that removal of introduced trout by electroshocking results in the enhancement of brook trout populations.

Twelve study streams in the Park were grouped as control and treatment streams. Removal efforts of one, two, and three passes consecutively were conducted on treatment streams to determine the effort needed to control rainbow trout populations. …

Effects Of Acid Ph On Embryonic And Juvenile Freshwater Fish, Barbara A. Ramey, Lee E. Colton

KWRRI Research Reports

The effects of sulfuric acid on embryos, larvae, and juvenile fish were examined using standard bioassay techniques, as well as in a preference/ avoidance behavioral test. The objectives were to compare the sensitivities of the various ages of fish to acid and to assess the use of the behavioral test in a hazard assessment program. In an 8-day static renewal bioassay, embryos and larvae of the fathead minnow were not affected at a pH of 4.92 and above, but pH 3.57 produced complete mortality prior to hatching. In 96- hr acute bioassays, 8-wk juvenile fathead minnows survived 100% at pH's …

Lambing Performance Of Morlam And Dorset Ewes Under Accelerated Lambing Systems, L. C. Iniguez, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Two accelerated lambing systems, Morlam using Morlam sheep (USDA, Beltsville 1966 to 1975) and Carnal using Dorset ewes (Cornell 1978 to 1981), were evaluated for first lambing ages, interlambing intervals and conception probabilities. Morlam ewes were continuously exposed to rams over the year, while Carnal Dorset ewes were exposed every other month. Morlam lambs were mated as early as 367 d of age and Carnal Dorset lambs as early as 340 d. Early lambing was associated with higher rates of perinatal mortality (P>.05) and smaller litter size (P<.O1). Lambing years among Morlam ewes and season of birth of Carnal Dorset ewes influenced (P<.01) their first lambing ages. Lambing intervals averaged 293 and 303 d among Morlam and Carnal Dorset ewes, respectively. Age at first lambing and season in which the previous lambing occurred with influential factors (P<.01) on lambing intervals of Morlam ewes; longer intervals resulted when ewe lambs were mated at early ages (<12 mo), and when the previous lambing occurred in winter. Estimates of conditional probabilities of conception by month given the occurrence of estrus, reflected seasonal changes in both systems. The overall probability of conception for the Morlain system (P=.16) was relatively higher than that for the Carnal Dorset system (P=.14); numbers of lambings per ewe per yr were 1.28 and 1.21, respectively. Estimates of heritability for age at first lambing, lambing interval and conception probability were. 31, .06 and .30, respectively.

Body Size And Condition, Timing Of Breeding, And Aspects Of Egg Production In Eastern Kingbirds, Michael T. Murphy

Biology Faculty Publications and Presentations

Variation in timing of breeding in Eastern Kingbirds (Tyrannus tyrannus) was correlated only weakly with external morphological characters, but was correlated positively and significantly with estimates of body size based on measurements of skeletons and muscle weights. Small females apparently held a reproductive advantage in being able to mobilize resources for reproduction before large females. Egg weight was independent of all measures of female size, but was directly and significantly (P = 0.03) correlated with standard flight muscle weight, a relative index of body condition. Egg size was thus a function more of female body condition than size. On average, …

Brood Parasitism Of Eastern Kingbirds By Brown-Headed Cowbirds, Michael T. Murphy

Biology Faculty Publications and Presentations

Understanding why brood parasites lay eggs in the nests of hosts that reject eggs is hampered by insuf-ficient data on the frequency with which parasites lay in rejecter nests, and by ignorance of which in-dividuals practice this seemingly inappropriate be-havior. Parasitism rates of rejecters can be deter-mined only when host nests are observed during egg laying because most parasite eggs are rejected rapidly (e.g. Scott 1977). Even then, however, a certain per-centage of parasitized nests may go undetected. De-termining the selective value of host defense mech-anisms also depends on knowledge of the frequency of parasitism, and the amount of reproductive …

Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.
