Interactions Of Sandhill Cranes And Whooping Cranes With Foreign Objects In Florida, Martin J. Folk, Stephen A. Nesbitt, Marilyn G. Spalding
Interactions Of Sandhill Cranes And Whooping Cranes With Foreign Objects In Florida, Martin J. Folk, Stephen A. Nesbitt, Marilyn G. Spalding
Proceedings of the North American Crane Workshop
During studies of Florida sandhill cranes (Grus canadensis pralensis), greater sandhill cranes (G. c. tabida), and whooping cranes (G. americana) in Florida, we documented cases where these birds were in contact with human-produced objects that resulted in injury or death. We describe >40 instances in which cranes collided with powerlines or fences, became entangled in string or fishing line, or ingested foreign objects. The effect of human-produced objects on crane populations, particularly small populations, may be significant.

Diversity And Abundance Of Seaweeds On The Coral Reef Flats At Cape Rachado, West Coast Peninsular Malaysia, Jillian Lean Sim Ooi
Student Works (2000-2009)
Three sites on the fringing coral reef flats at Cape Rachado, West Coast Peninsular Malaysia, were selected for the study of seaweed diversity and abundance. Each of these sites was identifiable with exposure to a particular environmental stress. Site A suffered from heavy loads of total suspended solids (TSS) caused by the removal of its adjoining coastal mangrove stand. Site B, by virtue of its accessibility and location on a popular stretch of beach, received a greater number of swimmers and beachwalkers. Water effluent (sewage) outlets from the various resorts lining the coast were observed at sites A and B. …

Managing Minnesota's Recovered Wolves, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The Minnesota wolf (Canis lupus) population was estimated by the Minnesota Department of Natural Resources at 2,450 during winter 1997-1998 and had increased at an average annual rate of 4.5°% since winter 1988-1989. The population may be removed from the federal endangered species list by 2002, and management would then return to the state. A federal recovery team recommended a population goal of 1,250-1,400 wolves for Minnesota, with none in the agricultural region. A plan approved by the Minnesota legislature, however, continues the protection of wolves, except for pet and livestock depredation control, for at least 5 years …

Harold W. Manter Laboratory of Parasitology: Faculty Publications
Biodiversity survey and inventory have resulted in new information on the distribution of Protostrongylidae in Dall’s sheep (Ovis dalli dalli) from the Northwest Territories (Northwest Territories, Canada) and from Alaska (Alaska, USA). In 1998, Parelaphostrongylus odocoilei adults were found for the first time in the skeletal muscles of Dall’s sheep in the Mackenzie Mountains (Northwest Territories). Adult P. odocoilei were associated with petechial and ecchymotic hemorrhages and localized myositis; eggs and larvae in the lungs were associated with diffuse granulomatous pneumonia. Experimental infections of the slugs Deroceras laeve and Deroceras reticulatum with dorsal-spined first-stage larvae assumed to be …

Among the objectives of the study are to survey and document the diversity and richness of the Zingiber species for the purpose of conservation. A total of 144 accessions from 32 Zingiber species including 8 varieties have been recorded throughout Peninsular Malaysia. These represent 20% out of the 150 species in the Zingibcraceae family, known to exist in Malaysia. Nine new species and two new varieties have been described. An anatomical study was conducted on 15 Zingiber species based on observation of anatomical structures of the leaves and petioles. The anatomy of the leaves and petioles shows some variation of …

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
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 …

A Phylogenetic Hypothesis For Species Of The Genus Taenia (Eucestoda: Taeniidae), Eric P. Hoberg, Arlene Jones, Robert L. Rausch, Keeseon S. Eom, Scott Lyell Gardner
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cladistic analysis of a numerical data matrix describing 27 characters for species of Taenia resulted in four most parsimonious phylogenetic trees (174 steps; consistency index = 0.28; homoplasy index = 0.72; retention index = 0.48). Monophyly for Taenia is diagnosed by the metacestode that is either a cysticercus or a form derived from a bladder-like larva; no other unequivocal synapomorphies are evident. Tree structure provides no support for recognition of a diversity of tribes or genera within the Taeniinae: Fimbriotaeniini and Taeniini have no phylogenetic basis. Hydatigera, Fimbriotaenia, Fossor, Monordotaenia, Multiceps, Taeniarhynchus, Tetratirotaenia must …
Leadership In Wolf, Canis Lupus, Packs, L. David Mech
Leadership In Wolf, Canis Lupus, Packs, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
I examine leadership in Wolf (Callis lupus) packs based on published observations and data gathered during summers from 1986 to 1998 studying a free-ranging pack of Wolves on Ellesmere Island that were habituated to my presence. The breeding male tended to initiate activities associated with foraging and travel, and the breeding female to initiate, and predominate in, pup care and protection. However, there was considerable overlap and interaction during these activities such that leadership could be considered a joint function. In packs with multiple breeders, quantitative information about leadership is needed.
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
We used simple linear regression to analyze 8-23 years of data on a wolf (Canis lupus) population and human harvest of white-tailed deer (Odocoileus virginianus) bucks in northeastern Minnesota to determine any effects of wolves on buck harvesting. Over the long term, wolves accounted for at least 14-22% inter-year variation in buck harvest in the region, but an unknown amount of variation in hunter effort have obscured any more precise estimate. For part of the area with poorest habitat, we found strong relationships (r2 = 0.66-0.84) between annual wolf numbers and buck harvests from 1988 …
Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul
Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolf (Canis lupus) depredations on livestock cause considerable conflict and expense in Minnesota. Furthermore, claims are made that such depredations are fostered by the type of animal husbandry practiced. Thus, we tried to detect factors that might predispose farms in Minnesota to wolf depredations. We compared results of interviews with 41 cattle farmers experiencing chronic cattle losses to wolves (chronic farms) with results from 41 nearby "matched" farms with no wolf losses to determine farm characteristics or husbandry practices that differed and that therefore might have affected wolf depredations. We also used a Geographic Information System (GIS) to …

The Dyke Marsh Preserve Ecosystem, David W. Johnston
The Dyke Marsh Preserve Ecosystem, David W. Johnston
Virginia Journal of Science
For over a century, Dyke marsh along the Potomac River just south of Alexandria, VA, has been a favorite site for natural history studies. Despite earlier attempts at diking to create agricultural land and dredging for sand and gravel, the remaining marsh represents the last major tidal freshwater wetland on the upper Potomac River, and is now owned and maintained by the National Park Service as the Dyke Marsh Preserve. In the present paper historical data on physical properties and biota are compared and contrasted with more recent biological investigations to show functioning ecosystem components, interrelationships among the flora and …

Prolonged Winter Undernutrition And The Interpretation Of Urinary Allantoin:Creatinine Ratios In White-Tailed Deer, Glenn D. Delgiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The urinary allantoin:creatinine (A:C) ratio (expressed in micromoles of allantoin to micromoles of creatinine) has shown potential as an index of recent winter energy intake in preliminary controlled studies of elk (Cervus elaphus) involving mild condition deterioration (up to 11% loss of body mass). To ensure reliable nutritional assessments of free-ranging cervids by measuring A:C ratios of urine in snow, it is essential to extend this work. We assessed the effect of moderate and severe winter nutritional restriction on urinary A:C ratios of captive white-tailed deer (Odocoileus virginianus) that lost up to 32% body mass and …
Clonal Growth Of Lithospermum Caroliniense (Boraginaceae) In Contrasting Sand Dune Habitats, Stephen G. Weller, Kathleen H. Keeler, Barbara A. Thomson
Clonal Growth Of Lithospermum Caroliniense (Boraginaceae) In Contrasting Sand Dune Habitats, Stephen G. Weller, Kathleen H. Keeler, Barbara A. Thomson
School of Biological Sciences: Faculty Publications
The occurrence of clonal growth of distylous Lithospermum caroliniense was investigated in a population in the Nebraska Sandhills, an area where sand dunes have been relatively stable for at least 1,500–3,000 yr, and compared to a population occurring at the Indiana Dunes, an area of active sand dune formation. Spatial autocorrelation analysis indicated the occurrence of significant clonal propagation of genetically based floral morphs at Arapaho Prairie, but not for the Indiana Dunes. Apparent clonal growth in the Sandhills population had no overall negative effect on pollen deposition or fecundity relative to the Indiana population, although in some large clones …

Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Seven adult female White-tailed Deer (Odocoileus virginianus) in northeastern Minnesota lived within 1.8 km of Wolf pack (Canis lupus) homesites without vacating their home ranges. Six of these deer and at least three of their fawns survived through the Wolf homesite period.
A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech
A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
This report documents a pack of 22-23 Wolves (Canis lupus) in central Minnesota. This is larger than the largest pack previously observed on the mainland in the midwestern U.s. during 650 wolf pack-years. Because this record-large pack preyed on White-tailed Deer (Odocoileus virginianus), one of the Wolfs smaller prey, it is evidence that pack size and prey size are not tightly related. It also indicates the size that Wolf packs can attain in the area if fully protected from human persecution.
Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech
Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
A lack of young muskoxen (Ovibos moschatus) and arctic hares (Lepus arcticus) in the Eureka area of Ellesmere Island, Northwest Territories (now Nunavut), Canada, was observed during summer 1998, in contrast to most other years since 1986. Evidence of malnourished muskoxen was also found. Early winter weather and a consequent 50% reduction of the 1997 summer replenishment period appeared to be the most likely cause, giving rise to a new hypothesis about conditions that might cause adverse demographic effects in arctic herbivores.
Durant l’été 1998, et ce, à la différence de la plupart des années depuis …
Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech
Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
We evaluated the accuracy and precision of tooth wear for aging gray wolves (Canis lupus) from Alaska, Minnesota, and Ontario based on 47 known-age or known-minimum-age skuIIs. Estimates of age using tooth wear and a commercial cementum annuli-aging service were useful for wolves up to 14 years old. The precision of estimates from cementum annuli was greater than estimates from tooth wear, but tooth wear estimates are more applicable in the field. We tended to overestimate age by 1-2 years and occasionaIIy by 3 or 4 years. The commercial service aged young wolves with cementum annuli to within …

Harold W. Manter Laboratory of Parasitology: Faculty Publications
Nuclear ribosomal sequence data from the internal transcribed spacers (ITS-1 and ITS-2), 5.8S subunit, and regions of the 18S and 28S genes were used to investigate sequence diversity among geographic samples of Nematodirus battus, and to infer phylogenetic relationships among Nematodirus species. Phylogenetic analysis of these data yielded strong support for relationships among species, depicting Nematodirus helvetianus and Nematodirus spathiger as sister-taxa and a clade of these two species and Nematodirus filicollis. This tree is consistent with caprine bovids as ancestral hosts, with a subsequent host shift to Bovinae in N. helvetianus. Eleven of fourteen N. battus sequences …

Salinity And Shade Preferences Result In Ovipositional Differences Between Sympatric Tiger Beetle Species, W. Wyatt Hoback, Douglas A. Golick, Tina Marie Svatos, Stephen M. Spomer, Leon G. Higley
Department of Entomology: Faculty Publications
1. Adult tiger beetles of the genus Cicindela often co-occur within a habitat but larvae do not. Larvae are sedentary and form usually permanent burrows at the site of oviposition where they require 1-3 years for development.
2. To test niche partitioning based on ovipositional preference, the behavior of two sympatric salt marsh tiger beetles, Cicindela circumpicta and C. togata (Coleoptera: Cicindelidae), were examined.
3. In laboratory studies, female C. circumpicta and C. togata distinguished between experimental salinities, with the former preferring 4 parts per thousand (ppt) and the latter preferring 12 ppt. In the field, C. circumpicta larvae were …

A study of abundance and biomass of the macrofauna in the mangroves in Sementa (Selangor) and Kuala Sepetang (Perak) was carried out monthly from September 1993 to December 1994 and from January 1994 to December 1994 . Two sites, a forested and a cleared area (deforested) were selected in each location for the study. Sampling for macrofauna was done by randomly selecting a spot and then pressing an aluminium quadrate of 40 cm x 40 cm into the sediment up to a depth of 20 cm. Eight quadrates were sampled on each occasion. The macrofauna community consisted of the following …

Student Works (2000-2009)
Fish and macroinvertebrate distribution and abundance in the Klang Strait (Malaysia) were investigated in relation to waler and bottom sediment characteristics. Thirteen water and bottom sediment parameters were measured and analysed using principal component analysis (PCA). PCA of these parameters distinguished three major habitat groupings in the Klang Strait: ( I) nearshore estuaries and mudflats, characterized by very turbid, lower salinity waters and muddy substrates, (2) offshore sandy habitat centred around the northern half of Angsa Bank, and characterized by less turbid, oxygen-riched and higher salinity water, and (3) offshore very fine sand habitat located largely on the southern half …

Distribution Of Some Heavy Metals In Selected Components Of A Coral Reef Ecoysystem At Cape Rachado, Malaysia, Abdulbaset Abdurrahman Ab. Abuissa
Student Works (2000-2009)
The coral reef ecosystem at Cape Rachado, is the only remaining fringing coral reef along the west coast of Peninsular Malaysia. The reef represents an interesting ecosystem with diverse flora and fauna and possesses a critical geographical location at the Straits of Malacca. The reef ecosystem especially the associated seaweed flora, was shown to be sensitive to development when increased silt levels led to loss of sensitive species of seaweeds. As yet, no study of heavy metal distribution and bioaccumulation in the coral reef area has been done. This study was aimed to investigate the distribution and bioaccumulation of iron, …
