Turkish Journal of Veterinary & Animal Sciences

The aim of this retrospective study was to evaluate the effects of breed, parity, and season on the reproductive parameters in bitches reared under a temperate climate. Breeding and pregnancy statuses, proestrus, estrus, and pregnancy durations, litter size, and cycle interval were recorded from German shepherds (GS, n = 34), Labrador retrievers (LA, n = 23), Belgian Malinois dogs (BM, n = 13), and Pointers (PO, n = 9) up to 10th parities. The mean age at first breeding (464.8 ± 26.2 days, mean ± SD) and the pregnancy rate (74.6%) were not different among breeds. The pregnancy duration was …

Conservation And Management Of Fallow Deer (Dama Dama Dama L.)On Lemnos Island, Greece, Mariama Mattila, Ioannis Hadjigeorgiou Jan 2015

Conservation And Management Of Fallow Deer (Dama Dama Dama L.)On Lemnos Island, Greece, Mariama Mattila, Ioannis Hadjigeorgiou

Turkish Journal of Veterinary & Animal Sciences

A small population of European fallow deer (Dama dama dama L.) was transferred to Myrina, Lemnos Island, Greece, in the early 1970s from the island of Rhodes. Since the Rhodian population may preserve a remarkable proportion of the original genetic diversity, it is necessary to preserve its offspring population. Our objective was to estimate population size, vegetation cover, and key stakeholder attitudes towards deer on the island, based on personal interviews. Following the visual inspection method, we estimated that there were 47 fallow deer in the fortress area (38 females, 3 males, and 6 fawns). For the total ground cover …

Evaluation Of The Genetic Resistance Status To Classical And Atypicalscrapie In Karacabey Merino Rams, Yalçin Yaman, Mehmet İhsan Soysal, Cemal Ün Jan 2015

Evaluation Of The Genetic Resistance Status To Classical And Atypicalscrapie In Karacabey Merino Rams, Yalçin Yaman, Mehmet İhsan Soysal, Cemal Ün

Turkish Journal of Veterinary & Animal Sciences

Scrapie, the oldest prion disease of sheep, has two types: classical and atypical scrapie. It was determined that some nucleotide polymorphisms in the PrP coding gene have affected classical and atypical scrapie susceptibility. Consequently, EU member states have established breeding programs aiming to increase genetic resistance of their flocks to classical scrapie. These breeding programs have primarily been implemented in economically important breeds. Thus, we investigated classical and atypical scrapie related PrP genotypes of the Karacabey merino breed, which is of great economic importance in western regions of Turkey. In relation to classical scrapie, three alleles (ARR, ARQ, and VRQ) …

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America.

Climatic Preferences And Distribution Of 6 Evolutionary Lineages Oftyphlops Vermicularis Merrem, 1820 In Turkey Using Ecological Niche Modeling, Serkan Gül, Yusuf Kumlutaş, Çeti̇n Ilgaz Jan 2015

Climatic Preferences And Distribution Of 6 Evolutionary Lineages Oftyphlops Vermicularis Merrem, 1820 In Turkey Using Ecological Niche Modeling, Serkan Gül, Yusuf Kumlutaş, Çeti̇n Ilgaz

Turkish Journal of Zoology

According to evolutionary biologists, ecology is a very important factor in speciation. Ecology may be effective at driving adaptive divergence between lineages in different environments and climatic conditions. Because Anatolia has major mountain belts, paleogeographic characteristics, and unique climatic traits, it plays an important role in speciation and shows a barrier effect for many terrestrial species. In this study, we investigated the climatic preferences of 6 isolated evolutionary lineages of Typhlops vermicularis in Anatolia using ecological niche modeling. Our results revealed that both glacial (Last Glacial Maximum) and interglacial (Last Interglacial) modeling, as well as current modeling, showed the most …

A New And Simple Technique For The Isolation Of Symbiotic Bacteria Associated With Entomopathogenic Nematodes (Heterorhabditidae And Steinernematidae), Derya Uluğ, Canan Hazir, Selçuk Hazir Jan 2015

A New And Simple Technique For The Isolation Of Symbiotic Bacteria Associated With Entomopathogenic Nematodes (Heterorhabditidae And Steinernematidae), Derya Uluğ, Canan Hazir, Selçuk Hazir

Turkish Journal of Zoology

This study describes a new, simple, and economical method for isolation of symbiotic bacteria from entomopathogenic nematodes. Isolation of the symbiotic bacteria from entomopathogenic nematodes is useful for mass production of the nematodes. In addition to traditional isolation methods from infected insect larvae or infective juveniles, we show a new method of isolating symbiotic bacteria from either gravid females or females in the endotokia matricida stage, producing symbiont colonies after a very short period of surface sterilization.

University Faculty and Staff Publications

Documenting and responding to species invasions requires innovative strategies that account for ecological and societal complexities. We used the recent expansion of Indo-Pacific lionfish (Pterois volitans/miles) throughout northern Gulf of Mexico coastal waters to evaluate the role of stakeholders in documenting and responding to a rapid marine invasion. We coupled an online survey of spearfishers and citizen science monitoring programs with traditional fishery-independent data sources and found that citizen observations documented lionfish 1–2 years earlier and more frequently than traditional reef fish monitoring programs. Citizen observations first documented lionfish in 2010 followed by rapid expansion and proliferation in …

Observations Of Hippopotamus H. Amphibius In The Little Scarcies River Of Sierra Leone And Arguments For Their Conservation Based On Roles They Play In Riverine Grasslands And Nutrient Loading, Lindsey R. Perry

Dissertations, Master's Theses and Master's Reports

A small population of Hippopotamus amphibius remains in Sierra Leone and conservation efforts may be needed to support the Hippos and their indirect benefits to fisheries and grassland production. The hippo is a known ecosystem engineer, and a potentially important contributor of nutrients to the river systems they inhabit supporting the food web and local fisheries. In this study I observed hippos in the Little Scarcies River and uplands of the Outamba-Kilimi National Park to estimate their numbers and ultimately their potential input of nutrients into the river. Hippos forage at night in grasslands neighboring rivers, removing up to 3.62 …

Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer Jan 2015

Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Northern Range (NR) of Yellowstone National Park (YNP) hosts a higher prey biomass density in the form of elk (Cervus elaphus L., 1758) than any other system of gray wolves (Canis lupus L., 1758) and prey reported. Therefore, it is important to determine whether that wolf–prey system fits a long-standing model relating wolf density to prey biomass. Using data from 2005 to 2012 after elk population fluctuations dampened 10 years subsequent to wolf reintroduction, we found that NR prey biomass predicted wolf density. This finding and the trajectory of the regression extend the validity of the model …

Harvest Demographics Of Temperate-Breeding Canada Geese In South Dakota, 1967–1995, Jeffrey S. Gleason, Jonathan A. Jenks, David E. Naugle, Paul W. Mammenga, Spencer J. Vaa, Jennifer M. Pritchett Jan 2015

Harvest Demographics Of Temperate-Breeding Canada Geese In South Dakota, 1967–1995, Jeffrey S. Gleason, Jonathan A. Jenks, David E. Naugle, Paul W. Mammenga, Spencer J. Vaa, Jennifer M. Pritchett

Human–Wildlife Interactions

In South Dakota, breeding giant Canada geese (Branta canadensis maxima) have increased substantially, and harvest management strategies have been implemented to maximize hunting opportunity (e.g., special early-September seasons) on local, as well as molt-migrant giant Canada geese (B. c. interior) while still protecting lesser abundant Arctic breeding Canada geese and cackling geese (e.g., B. hutchinsii, B. minima). Information on important parameters, such as survival and recovery rates, are generally lacking for giant Canada geese in the northern Great Plains. Patterns in Canada goose band recoveries can provide insight into the distribution, chronology, and harvest pressures …

Methodology For Estimating Deer Browsing Impact, Timothy G. Pierson, David S. Decalesta Jan 2015

Methodology For Estimating Deer Browsing Impact, Timothy G. Pierson, David S. Decalesta

Human–Wildlife Interactions

Because there were no reliable indicators of deer browsing on tree seedling regeneration, we developed methodology that can be used to measure deer browsing impact. We compared 11 years (2002 to 2012) of annual estimates of deer density with coarse (percent-plots-no-regeneration, percent-plots-no-impact) and fine (3 levels of impact on 6 indicator seedling species) indicators within a 29,642-ha study area in northwestern Pennsylvania. Coarse and fine measures met established criteria for indicators of environmental stress (e.g., high deer density); they were predictive of stresses that can be: avoided by management; integrative with causes of stress; responsive to disturbances and changes over …

Changes In Distribution Of Canada Geese Nesting In Arkansas, M. Eliese Ronke, David G. Krementz

Human–Wildlife Interactions

The reintroduced Canada goose (Branta canadensis) population in Arkansas has grown in range and abundance in recent decades. We determined the geographic range of Arkansas resident Canada geese from 2004 to 2012 using volume contour maps from citizen science observations using eBird, a citizen science website, and hunter recovery locations from the U.S. Geological Survey Bird Banding Laboratory. Resulting maps indicate an increase in Canada goose encounters toward northwestern and southwestern Arkansas from the original relocations in the Arkansas River valley. We examined movement of Canada geese banded and recovered in Arkansas by determining the distance and angle …

Characterizing Nontarget Species Use At Bait Sites For White-Tailed Deer, Brent Bowman, Jerrold L. Belant, Dean E. Beyer Jr., Deborah Martel

Human–Wildlife Interactions

Baiting white-tailed deer (Odocoileus virginianus) has evolved into a controversial issue of wildlife management. During August–September 2012, we established a grid of 64 cameras in the Upper Peninsula of Michigan at sites baited with corn that simulated legal bait sites for white-tailed deer to characterize presence, diversity, and frequency of species use. We detected >20 species of wildlife that visited bait sites. We categorized 3,177 of 11,194 images as independent detections (i.e., species detected >1 hour apart). White-tailed deer had the greatest detection rate (47%), but overall detections of nontarget species was slightly greater (53%). Most frequent nontarget …

Brown Bear And Human Recreational Use Of Trails In Anchorage, Alaska, Jessica A. Coltrane, Rick Sinnott Jan 2015

Brown Bear And Human Recreational Use Of Trails In Anchorage, Alaska, Jessica A. Coltrane, Rick Sinnott

Human–Wildlife Interactions

Anchorage, Alaska, has 301,000 human residents and hundreds of thousands of visitors each year. Anchorage also supports a viable population of brown bears (Ursus arctos). As a result, human–bear encounters are common. We used camera traps to monitor recreational trails near salmon spawning streams at 3 study sites during the summers of 2009 to 2012 to better understand daily and seasonal activity patterns of bears and humans on these trails. The more remote study sites had the least human activity and the most bear activity. Human–bear encounters were most likely to occur from July through early September due …

Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband Jan 2015

Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband

Human–Wildlife Interactions

Managing damage by wild vertebrates often is important, and wildlife damage management (WDM) has incorporated important tenets of integrated pest management (IPM). However, largely separate academic backgrounds have nurtured the IPM and WDM communities. The controversial “hot button” topics have tended to differ. While WDM research and outreach have received some IPM funding, and wildlife studies occasionally appear in IPM journals, attendance at infrequent wildlife sessions during IPM meetings has been sparse. The objectives of this paper are to review important examples of collaboration, and evaluate possibilities for future synergy between these related disciplines.

Winter Habitat Associations Of Blackbirds And Starlings Wintering In The South-Central United States, Matthew Strassburg, Shawn M. Crimmins, Patrick C. Mckann, Wayne E. Thogmartin

Human–Wildlife Interactions

Birds can cause extensive crop damage in the United States. In some regions, depredating species comprise a substantial portion of the total avian population, emphasizing their importance both economically and ecologically. We used the National Audubon Society Christmas Bird Count data from the south-central United States and mixed-effects models to identify habitat factors associated with population trend and abundance for 5 species: red-winged blackbird (Agelaius phoeniceus), common grackle (Quiscalus quiscula), rusty blackbird (Euphagus carolinus), Brewer’s blackbird (Euphagus cyanocephalus), and European starling (Sturnus vulgaris). Overall, we found positive associations between bird …

Does Body Condition Affect Immediate Post-Capture Survival Of Ungulates?, Louis C. Bender Jan 2015

Does Body Condition Affect Immediate Post-Capture Survival Of Ungulates?, Louis C. Bender

Human–Wildlife Interactions

Many factors are known or are thought to increase vulnerability to capture-related mortality in ungulates. I compared body condition of Rocky Mountain elk (Cervus elaphus nelson), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) to assess whether those that survived capture differed from those that did not. Fate of ungulates was generally not related to condition (F1,646 = 1.6; P = 0.21), and this relationship was similar among species (species × fate interaction: F4,646 = 1.3; P = 0.29), season of capture (species × season × fate interaction: F6,646 = …

Quantitative Assessment Of Bullet Fragments In Viscera Of Sheep Carcasses As Surrogates For White-Tailed Deer, Luis Cruz-Martinez, Marrett D. Grund, Patrick T. Redig Jan 2015

Quantitative Assessment Of Bullet Fragments In Viscera Of Sheep Carcasses As Surrogates For White-Tailed Deer, Luis Cruz-Martinez, Marrett D. Grund, Patrick T. Redig

Human–Wildlife Interactions

Avian scavengers, such as bald eagles (Haliaeetus leucocephalus), can be exposed to lead through the consumption of spent lead from ammunition in carcasses of animals shot with lead-based projectiles. Few studies have examined the degree of bullet fragmentation in viscera (offal) of game mammals. Our objective was to quantify the number of bullet fragments deposited in sheep carcasses shot with different types of lead and lead-free, high-velocity centerfire rifle bullets and with lead projectiles fired from shotguns and muzzleloader rifles marketed for hunting white-tailed deer (Odocoileus virginianus). We hypothesized that after controlling for velocity, angle of …

Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund Jan 2015

Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund

Human–Wildlife Interactions

Most state wildlife agencies consider public input in the management of whitetailed deer (Odocoileus virginianus) populations. In 2013, we surveyed deer hunters (n = 3,600) and landowners (n = 4,604) in southwest Minnesota to gauge their preferences for managing deer. We hypothesized a priori that, irrespective of their perceived impacts of deer, hunters would prefer deer populations to be increased and landowners would prefer deer populations to be decreased. Our findings suggest that defining stakeholder groups according to primary associations with deer (i.e., farming and hunting) accurately categorized differences in tolerance levels for deer populations in …
