Regulated Commercial Harvest To Manage Overabundant White-Tailed Deer: An Idea To Consider?, Kurt C. Vercauteren, Charles W. Anderson, Timothy R. Van Deelen, David Drake, W. David Walter, Stephen Vantassel, Scott E. Hygnstrom

United States Department of Agriculture Wildlife Services: Staff Publications

Declines in hunter recruitment coupled with dramatic growth in numbers of white-tailed deer (Odocoileus virginianus) have challenged our ability to manage deer populations through regulated hunting. We review the efficacy of current regulated hunting methods and explain how they are unable to reduce deer numbers sufficiently in some environments. Regulated commercial harvest would provide an additional tool to help state wildlife agencies manage overabundant populations of white-tailed deer. We outline potential means to govern regulated commercial deer harvest and explain how it is compatible with the North American Model of Wildlife Conservation. We identified several benefits, including reduced …

Cd-Induced Responses In Plasma Ionic Regulation And Oxidative Stress In Rainbow Trout (O. Mykiss) Or Lake Whitefish (C. Clupeaformis) During Chronic Waterborne Exposure, Amanda Mancini

Theses and Dissertations (Comprehensive)

During chronic exposure to Cd or other metals, freshwater fish generally undergo physiological changes that results in acclimation, following a phase of damage and subsequent repair. The mechanisms associated with deleterious cellular effects induced by Cd throughout long-term exposures are less understood than those of acute toxicity, and may relate to an over-production of reactive oxygen species. The objectives of the present study were to examine the changes in, and relationship between, tissue-specific oxidative damage and antioxidant response, as well as plasma ionic regulation and tissue accumulation, in two freshwater salmonids throughout chronic Cd exposure. Rainbow trout (O. mykiss …

Linking Cd Accumulation And Effect In Resistant And Sensitive Freshwater Invertebrates, Tony Straus

Theses and Dissertations (Comprehensive)

There has been recent discussion within the field of environmental toxicology as to the viability of using the bioaccumulation of a chemical toxicant to predict toxic effects. Current literature has shown this concept to carry some merit, although there is a major flaw in that with many cases, namely those involving sensitive species, body burdens cannot be reliably linked to effects (Adams et al. (2010)). Bearing this issue in mind the goal of this thesis was to assess the viability of using bioaccumulation as a measure of effect in a different way.

The proposed idea utilized Cd accumulation in a …

Characterization Of Photochromogenic Mycobacterium Spp. From Chesapeake Bay Striped Bass Morone Saxatilis, D. T. Gauthier, A. M. Helenthal, M. W. Rhodes, W. K. Vogelbein, H. I. Kator

Biological Sciences Faculty Publications

A large diversity of Mycobacterium spp. has been isolated from striped bass Morone saxatilis in Chesapeake Bay, USA. The new species M. shottsii and M. pseudoshottsii are the dominant isolates, while the classical fish pathogen M. marinum is found much less frequently. M. fortuitum and M. chelonae, other Mycobacterium spp. known to commonly infect fishes, have not yet been aseptically isolated from striped bass within Chesapeake Bay. While M. pseudoshottsii and M. shottsii have been phenotypically and genotypically characterized, other less common mycobacterial isolates have not. In the present study, we describe 17 photochromogenic isolates from Chesapeake …

Disease Effects On Lobster Fisheries, Ecology, And Culture: Overview Of Dao Special 6, Donald C. Behringer, Mark J. Butler Iv, Grant D. Stentiford

Biological Sciences Faculty Publications

Lobsters are prized by commercial and recreational fishermen worldwide, and their populations are therefore buffeted by fishery practices. But lobsters also remain integral members of their benthic communities where predator-prey relationships, competitive interactions, and host-pathogen dynamics push and pull at their population dynamics. Although lobsters have few reported pathogens and parasites relative to other decapod crustaceans, the rise of diseases with consequences for lobster fisheries and aquaculture has spotlighted the importance of disease for lobster biology, population dynamics and ecology. Researchers, managers, and fishers thus increasingly recognize the need to understand lobster pathogens and parasites so they can be managed …

Cost-Benefit Analysis Of Managed Shotgun Hunts For Suburban White-Tailed Deer, Ryan D. Hubbard, Clayton K. Nielsen

Human–Wildlife Interactions

Deer managers often utilize managed hunts to curtail burgeoning white-tailed deer (Odocoileus virginianus) populations in suburban areas. Although several studies have used population modeling to focus management, these efforts generally provide only harvest numbers, without considering the spatial placement of hunters on the landscape. Further, few studies have modeled management effort as deer density changes during the hunt. We modeled 2 types of managed shotgun hunts, a replacement hunt, where the stand of each successful hunter would be filled the following day, thus, ensuring the same number of hunters would be present each day of the hunt, and …

Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks

Human–Wildlife Interactions

Damage to field corn (Zea mays) by white-tailed deer (Odocoileus virginianus) can be substantial, resulting in millions of dollars lost annually. Numerous methods exist to minimize deer depredation, but all have met with varying degrees of success. Currently, little information is available on preference of white-tailed deer for corn hybrids during the growing season and how that preference might affect depredation patterns. We used adult female white-tailed deer in captivity to study the effect of herbicide treatments on deer-use (treatment versus no treatment) of corn in 2005 and to document preference among specific corn hybrids in …

Feed Depredation By European Starlings In A Kansas Feedlot, Brandon E. Depenbusch, James S. Drouillard, Charles D. Lee

Human–Wildlife Interactions

Confinement cattle-feeding operations have been associated with large populations of starlings (Sturnus vulgaris) during the winter months. Starlings can eat nearly 1 kg each of feed per month (Besser et al. 1968). In the first of our 2 studies, we evaluated feed selection and feed depredation by starlings using 5 concentrate-based cattle finishing diets. Four diets evaluated were in traditional meal-type form, and 1 diet was an extruded pellet. We placed rations into a section of the feed trough that we made accessible to starlings but not to cattle. Of the original 13.6 kg of steam-flaked corn and …

Livestock And Domestic Dog Predations By Wolves In Michigan, Justin L. Edge, Dean E. Beyer Jr., Jerrold L. Belant, Mark J. Jordan, Brian J. Roell

Human–Wildlife Interactions

Wolves (Canis spp.) have recolonized the Great Lakes region and expanded into agricultural areas where there is increasing concern of conflict with livestock. We documented 121 wolf predation events on captive or domestic animals in the Upper Peninsula (UP) of Michigan between April 1996 and April 2009. We investigated the relationship between annual wolf abundance and predation events, seasonality of predations on livestock, and the association between previous winter severity and predations on livestock. The annual number of predations on livestock increased with wolf abundance, and overall, predations on cattle and calves increased during calving season. We observed a …

Too Many Hogs? A Review Of Methods To Mitigate Impact By Wild Boar And Feral Hogs, Giovanna Massei, Sugoto Roy, Richard Bunting

Human–Wildlife Interactions

Feral hogs (Sus scrofa) are among the most widely-distributed mammals in the world and have the highest reproductive output compared with other ungulates. Worldwide, feral hogs are increasing in range and numbers. Human–feral hog conflicts include impact on abundance and richness of plant and animal species, crop damage, predation on livestock, vehicle collisions, and disease transmission. We reviewed methods employed to mitigate the impact of feral hogs on human activities and discussed these methods in terms of effectiveness, feasibility, costs, and social acceptance. Traditional methods of control include trapping, angering, shooting, poisoning, and Judas hogs. Nonlethal methods of …

Good Fences Make Good Neighbors: Implementation Of Electric Fencing For Establishing Effective Livestock-Protection Dogs, Thomas M. Gehring, Kurt C. Vercauteren, Anna C. Cellar

Human–Wildlife Interactions

To be effective, livestock protection dogs (LPDs) must be carefully integrated with the livestock they will be protecting. Others have developed guidelines to assist producers in this training and assimilation process. In many areas fencing is necessary; however, guidelines for containing LPDs and their livestock behind electric fencing are lacking. We present results from larger projects involving LPDs where we encountered issues with fencing and preventing LPDs from roaming from their owner’s property. We found that ranging and escaping from pastures was exhibited by LPDs that were not properly introduced and trained to electric fencing at an early age. LPDs …

Public Perceptions Of Bears And Management Interventions In Japan, Ryo Sakurai, Susan K. Jacobson

Human–Wildlife Interactions

Conservation of bears is a challenge globally. In Japan, Asiatic black bears (Ursus thibetanus) and brown bears (Ursus arctos) are considered a nuisance because of agricultural and property damage and personal human danger due to occasional human casualties. Reduction of human–bear conflicts in Japan would improve long-term conservation of bears and reduce risks to human health and safety. To understand Japanese perceptions of and experience with bears, we analyzed results of 5 public surveys and reviewed 29 articles from the research and gray literature in Japan. We compared recommendations for interventions to reduce human–bear conflicts with …

Factors Governing Risk Of Cougar Attacks On Humans, David Mattson, Kenneth Logan, Linda Sweanor

Human–Wildlife Interactions

Since the 1980s wildlife managers in the United States and Canada have expressed increasing concern about the physical threat posed by cougars (Puma concolor) to humans. We developed a conceptual framework and analyzed 386 human– cougar encounters (29 fatal attacks, 171 instances of nonfatal contact, and 186 close-threatening encounters) to provide information relevant to public safety. We conceived of human injury and death as the outcome of 4 transitions affected by different suites of factors: (1) a human encountering a cougar: (2) given an encounter, odds that the cougar would be aggressive; (3) given aggression, odds that the …

A Phylogeographic And Population Genetic Analysis Of A Widespread, Sedentary North American Bird: The Hairy Woodpecker (Picoides Villosus), John Klicka, Garth M. Spellman, Kevin Winker, Vivien Chua, Brian T. Smith

Ornithology Program (HRC)

The Hairy Woodpecker (Picoides villosus) has one of the broadest breeding distributions of any North American bird and is also one of the most morphologically variable with as many as 21 described subspecies. This wide distribution and high degree of phenotypic diversity suggests the presence of underlying genetic structure. We used ND2 sequence from 296 individuals from 89 localities throughout the Hairy Woodpecker distribution to address this question and to explore this species’ evolutionary history. Phylogenetic analyses identified three main Hairy Woodpecker clades, each ~1.5% divergent from one another. One clade was comprised of birds from boreal and eastern zones …

A Standardized Terminology For Describing Reproductive Development In Fishes, Nancy J. Brown-Peterson

Faculty Publications

As the number of fish reproduction studies has proliferated, so has the number of gonadal classification schemes and terms. This hasmade it difficult for both scientists and resourcemanagers to communicate and for comparisons to be made among studies. We propose the adoption of a simple, universal terminology for the phases in the reproductive cycle, which can be applied to all male and female elasmobranch and teleost fishes. These phases were chosen because they define key milestones in the reproductive cycle; the phases include immature, developing, spawning capable, regressing, and regenerating. Although the temporal sequence of events during gamete development in …

Maximum Swimming Speed Predictions For Mullus Barbatus (Linnaeus, 1758) And Diplodus Annularis (Linnaeus, 1758), Hüseyi̇n Özbi̇lgi̇n, Murat Pehli̇van, Fati̇h Başaran

Turkish Journal of Zoology

Maximum swimming speed of red mullet (Mullus barbatus) and annular sea bream (Diplodus annularis) was estimated based on muscle twitch experiments. The maximum estimated speed of red mullet (mean length: 16.9 cm) was 3.14 m/s (18.6 bl/s) at 26 °C. At 20 °C the maximum estimated speed of annular sea bream (mean length: 11.5 cm) was 1.92 m/s (16.7 bl/s). Maximum swimming speed of annular sea bream decreased as the temperature decreased.

Growth, The Length-Weight Relationship, And Reproduction In Vimba (Vimba Vimba L. 1758) Sampled From An Oligo-Mesotrophic Lake In Northwest Anatolia (Turkey), Hacer Okgerman, Mahmut Elp, Cumhur H. Yardimci

Turkish Journal of Zoology

The growth parameters and reproduction period in vimba (Vimba vimba L. 1758) sampled from Sapanca Lake were determined monthly between September 2003 and July 2004. The 335 vimba specimens caught ranged in age from 2^+ to 6^+ years, and the majority of the samples consisted of individuals of the 4^{+}-year-old age group. The length-weight relationship was estimated to be W = 0.0084 FL^{3.1797±0.0035} for males (r^2 = 0.94, P < 0.05) and W = 0.0089 FL^{3.1572±0.0033} for females (r^2 = 0.93, P < 0.05). Regression coefficients for sex were significant (t-test, P < 0.05). The slope (b) significantly differed (ANCOVA, P < 0.05) between months. The fact that the b values for male and female vimba specimens differed from 3.0 indicates that there was positive allometric growth. The von Bertalanffy equation was determined using Lt = 28.940 (1-exp {-0.123[t+2.193]}), \phi': 2.030, (r = 0.999) for males and Lt = 24.708 [1-exp {-0.205[t+1.464]}), \phi': 2.097, (r = 0.999) for females. The sex ratio was 1:1.86 (\chi^2; P < 0.05). The spawning period of vimba began at the end of April and continued until the beginning of July; the water temperature during this period was between 14.8 and 25.9 °C.

Turkish Journal of Zoology

Distribution and biometric information for Macropipus tuberculatus of the Strait of Sicily were obtained via an experimental bottom trawl survey carried out in 2000. The species occurred with low frequency (20%) and abundance (365 specimens), showing a scattered spatial distribution, split in 2 preferential depth levels (90-160 m and 230-460 m). Males were larger and more abundant than females. The carapace length width relationship was allometric positive (b > 1), and the carapace length weight relationship was isometric (b = 3).

Gender-Based Differences In Stride And Limb Dimensions Between Healthy Red-Wing Tinamou (Rhynchotus Rufescens) Temminck, 1815, Sandra Aidar De Queiroz, Ross Gordon Cooper

Turkish Journal of Zoology

The red-wing tinamou (Rhynchotus rufescens) is economically important as food. The current study investigated the limb and trunk characteristics in age-matched [year-of-hatch (yoh) 2004 and 2005], gender segregated birds, and determined differences in stride between cocks and hens. The locomotion trial was completed in a corridor of 0.6 × 2.36 m dimension. The girth was significantly higher in cocks than in hens, while body weight was slightly higher in hens. Cocks had a greater height than hens. The time to walk 2.36 m was longer for cocks than for hens. This was related to an attenuated speed and stride length …

Investigation Of The Influence Of The Juvenile Hormone Analogue Fenoxycarb On Major Hemolymph Proteins Of The Silkworm Bombyx Mori During The Last Larval Instar, Ramazan Uranli, Ebru Göncü, Osman Parlak

Turkish Journal of Zoology

Fenoxycarb 0-ethyl N-(2-(4-pheoxyphenoxy)-ethyl) carbamate is the most potent juvenile hormone analogue (JHA) against a variety of insect species including the silkworm Bombyx mori. In this study, we aimed to demonstrate the effects of this juvenile hormone on major hemolymph proteins of Bombyx mori during the fifth larval instar, by using fenoxycarb and clarifying the interactions between these proteins and the juvenile hormone. Topical applications of fenoxycarb to the fifth instar larvae of Bombyx mori were performed immediately after the fourth ecdysis (on day 0) and at the beginning of the prepupal period (on day 6). Fenoxycarb application on day 0 …
