TY - JOUR. T1 - Antleroma in a Free-ranging White-tailed Deer (Odocoileus virginianus). AU - Munk, Brandon A.. AU - Garrison, E.. AU - Clemons, B.. AU - Keel, Michael K. PY - 2015/1/29. Y1 - 2015/1/29. N2 - A 2-year-old male free-ranging white-tailed deer (Odocoileus virginianus) was diagnosed with bilateral expansile tumors of antler origin. The deer was found dead by a landowner in High Springs, Florida. Two roughly spherical, multilobular, broad-based, bony, velvet-covered masses originated from each antler pedicle. These masses replaced or displaced many of the bones and soft tissues of the skull and extended through the left cribriform plate and the right petrous temporal bone, compressing portions of the brain. Microscopically, the masses closely resembled normal-growing antler, containing all the elements thereof but with areas of necrosis and hemorrhage suggestive of ischemi or trauma. Tumorlike outgrowths termed antleromas have been described in free-ranging and captive cervids and ...
White-tailed deer populations in suburban and urban areas have expanded dramatically in recent years and have produced widespread problems across the United States. Currently there are several methods to control the size and growth of deer populations. I modeled the use of immunocontraception on a hypothetical, urban deer population and found 60% of the does would need to be vaccinated with porcine zona pellucida (PZP) in order to stabilize the herd. I also found that the population would decrease after 70% of the females received the immunocontraceptive. The cost of administering the drug significantly out-weighs the price per dose of PZP, making the use of immunocontraceptives on urban white-tailed deer populations cost-inefficient..

The exact incubation period for natural CWD in cervids is not known and may vary between species. However the youngest clinically affected free-living elk (Cervus elaphus nelsoni - Rocky Mountain Elk (Cervus elaphus - Red deer)) was 21 months old, the youngest captive elk was 17 months. In Odocoileus hemionus - Mule deer the youngest naturally infected individual with clinical signs was 18 months old. In Odocoileus virginianus - White-tailed deer the youngest individual with clinical signs was 1.5 years old. Data from two outbreaks in a wildlife research facility in Colorado suggested an incubation period of 18-36 months. An incubation period of 17-24 months was seen following experimental infection by intracerebral inoculation. With experimental oral infection the incubation period was 12-34 months in elk while in mule deer the earliest onset of clinical signs occurred at 15 months after oral inoculation ...
The authors studied some reproductive characteristics of wild female sika deer (Cervus nippon yesoensis Heude, 1884) in Ashoro District, Hokkaido. Large numbers of females attained sexual maturation at the age of yearling, and the pregnancy rate of y
Odocileus hemionus columbianus. Black-tailed Deer are a sub-species of Mule Deer (Odeocileus hemionus hemionus) found west of the Cascade Mountains. Black-tailed Deer have all black tails, while Mule Deer have white tails with black tips. Otherwise Black-tailed Deer and Mule Deer are very similar, both in appearance and behavior. Black-tailed Deer, like Mule Deer, have large, fuzzy, mule-like ears, red-brown coats, and white rumps. These deer are found widely in the parks forested regions. In summer, bucks will move to higher elevations while does and fawns stay at lower regions. Deer are most active at dawn and dusk and they eat a variety of grasses and vegetation. In winter their diet shifts to include more twigs and woody vegetation ...
Some black-tailed deer populations have been declining in western Oregon and Washington, and often the declines are attributed to large-scale changes to the structure of their forest habitats. A common hypothesis is that use of herbicides in managed forests contributes to deer population declines by reducing availability of nutritious forbs and shrubs. This hypothesis will be tested in a study of the grazing behavior and nutritional status of trained black-tail deer on a variety of habitat types in forested landscapes. Investigators include Professor Lisa Shipley (Washington State University); Amy Ulappa (Ph.D. candidate at WSU); and Drs. Rachel and John Cook (NCASI). Preparations for field work include bottle-raising black-tailed deer fawns obtained from rehabbers across the western portion of Washington and from the Muckleshoot Tribe. The experimental herd includes 13 females and two males for breeding. Beginning in June 2012, Rachel and Amy will be taking these animals out into the woods in ...
CONCORD, N.H. - New Hampshires white-tailed deer population once again showed no evidence of chronic wasting disease (CWD), based on monitoring data gathered during the 2014 hunting season. New Hampshire Fish and Game Deer Biologist Dan Bergeron recently received results from a federally certified veterinary diagnostic laboratory that indicate that all the deer tissue samples taken during last falls hunting season tested negative for CWD. A total of 423 tissue samples were tested.. Chronic wasting disease is a neurological disorder that is fatal to white-tailed deer, mule deer, elk and moose, but the World Health Organization has concluded that there is no evidence that people can become infected with CWD.. CWD is transmitted by an abnormal prion protein present in the nervous system and lymphatic tissue of infected animals. These abnormal proteins are very stable and may persist in the environment for several years, posing a risk to animals that come into contact with them. The abnormal ...
A survey of 41 mule deer (Odocolleus hemionus) and three white-tailed deer (O. virginianus) for bovine tuberculosis was conducted on a Montana (USA) cattle ranch from 2 November 1993 through January 1994. Gross and microscopic lesions typical of tuberculosis were present in tonsil and lymph nodes of the head, thorax, and abdomen of one adult female mule deer. Additionally, a single microgranuloma considered morphologically suggestive of tuberculosis was present in one lymph node of the head of a second mule deer. Mycobacterial isolates from lymph nodes of the head and thorax of the first deer were identified as Mycobacterium bovis.
Several natural predators of white-tailed deer occur. Wolves, cougars, American alligators, jaguars (in the tropics), and humans are the most effective natural predators of white-tailed deer. These predators frequently pick out easily caught young or infirm deer (which is believed to improve the genetic stock of a population), but can and do take healthy adults of any size. Bobcats, Canada lynx, bears, wolverines, and packs of coyotes usually prey mainly on fawns. Bears may sometimes attack adult deer, while lynxes, coyotes, and wolverines are most likely to take adult deer when the ungulates are weakened by harsh winter weather.[12] Many scavengers rely on deer as carrion, including New World vultures, raptors, foxes, and corvids. Few wild predators can afford to be picky and any will readily consume deer as carrion. Records exist of American crows attempting to prey on white-tailed deer fawns by pecking around their face and eyes, though no accounts of success are given.[29] Occasionally, both ...
Abstract. White-tailed deer (Odocoileus virginianus) are an abundant mammal with a wide geographic distribution in the United States, which make them good sentinels for monitoring arboviral activity across the country. Exposure to various arboviruses has been detected in white-tailed deer, typically in conjunction with another diagnostic finding. To better assess the exposure of white-tailed deer to seven arboviruses, we tested 1,508 sera collected from 2010 to 2016 for antibodies to eastern equine encephalitis (2.5%), Powassan (4.2%), St. Louis encephalitis, (3.7%), West Nile (6.0%), Maguari (19.4%), La Crosse (30.3%), and bluetongue (7.8%) viruses. At least one arbovirus was detected in 51.3%, and exposure to more than one arbovirus was identified in 17.6% of the white-tailed deer sampled.
Sampling in Oneida County To Date Shows No Signs of CWD in Wild Herd. The New York State Department of Environmental Conservation (DEC) today announced that the initial round of sampling results for chronic wasting disease (CWD) in Oneida County wild deer has shown no signs of the disease to date in New York States wild deer population.. Sample tissues from 64 wild deer were sent to the New York State Veterinary Diagnostic Laboratory at Cornell University to be analyzed for CWD. None of the 64 samples showed a positive result for CWD. DEC has implemented intensive monitoring efforts after CWD was found in two captive white-tailed deer herds in Oneida County - the first incidents of CWD in New York State. Earlier this month, the State Department of Agriculture and Markets (DAM) completed testing of the captive deer and found a total of five positive results for CWD in the two captive herds.. In addition to sampling the wild deer population in the immediate area of the Oneida County farms, DEC ...
In an attempt to establish reference values for sperm morphology in wild red deer, genital tracts were collected from thirty-six 3-11 years old free-ranging, wild red deer stags (Cervus elaphus L) shot down during 3 consecutive mating seasons (1996-1998) at three different environmental regions of Poland, defining two major ecotypes: (i) highland (outer eastern Carpathian range, Bieszczady mountains) and, (ii) lowland (Mazuria and Pomerania) and studied within 4.5h-49h after death for testis (T), epididymides (E) and vesicular gland (VG) variables. Spermatozoa collected from the E-cauda were examined for motility and morphology (light and electron microscopy levels). Both T size and weight and VS-weight differed with age (P,0.05-0.01) while habitat influenced T size and weight (P,0.01) a well as sperm motility (P,0.05). Neither sperm numbers nor morphology showed significant differences, mostly owing to. the large variation recorded among stags (range 1-72%). Domain-grouped sperm morphological ...

The decline of the Siberian Musk Deers population began in China where most of the deer population was abundant. Most notably in the Sichuan plains, the musk production was accounted for 80% of the domestic trade in the 1950s.[4] New sightings of musk deer was later spotted in the upper northeast Asia and Russia; these spotted places soon opened their own musk market. After the 1980s, the production begins to steadily decline due to hunting for their musk glands. Then the cycle of over-harvesting the deers musk continued until the exploitation severely reduced the musk deers population. Another threat comes from the habitat loss by deforestation. For a long period, China cut more of its forest than they could replant. 200million cm3[4] of Chinas forest recourses were cut down in the past 25 years in order to harvest the timber stock in trade for commerce. Deforestation is a severe threat to the musk deers long term survival because the deer can only live in a few areas. ...
Chronic wasting disease (CWD) is a unique transmissible spongiform encephalopathy (TSE) of mule deer (Odocoileus hemionus), white-tailed deer (O. virginianus), and Rocky Mountain elk (Cervus elaphus nelsoni). Still many facts regarding this disease remain unclear. A very interesting brandnew article...

In general, feeding of wild deer is not a popular pastime in the UK and this is probably to their favour. Wildlife services in the USA have considerable problems with landowners putting out food for deer during the winter months. The issue revolves around the fact that deer are ruminants. As mentioned elsewhere (see Food & Feeding), deer share a syntrophic relationship with numerous species of microbe that breakdown the food they eat. Moreover, the species of bacteria, protozoa, fungi or archea present is related to the individual deers diet. Thus, a deer feeding on grass and saplings have different species of bacteria to one feeding on bark and heather. This presents a problem when putting out food for them.. In Montana, for example, people put out corn and hay for deer over the winter months. The deer-which have been grazing in spring pastures-dont have the gut microorganisms necessary to digest this food. Unfortunately, deer are understandably unaware of their digestive predicament and will ...
Were seeing deer densities of somewhere between 26 and 32 deer per mile in our area," says Wolff. "Ideally, according to the MASSWildlife biologists, the ideal carrying capacity is 6 to 8 deer per mile in our area. If we can significantly reduce the number of deer, it will help control the number of ticks and their potential for disease to spread.". The ongoing population among whitetail deer in the suburban area has led to an explosion in tick populations; capable of laying up to 3,000 eggs. The explosion has translated into more human-tick interactions that have led to the spread of diseases like babesiosis, anaplasmosis, Powwasan virus and Lyme disease.. In an effort to control numbers of suburban deer (and ticks), homeowners and municipalities are turning to Wolffs group, Mass Deer Service.. "Because these are residential areas, firearms arent really an option," says Wolff. "So what Ive done is created a group that insures and qualifies individual bowhunters to come into residential ...
The deer plague is out of control - and costing one farmer $80,000 a year. Hes not the only one - landholders around the state are out of pocket. NSW Farmers are lobbying for farmers rights to manage deer populations.
We found that oestrous hinds given a relative choice between the two male pitch variants spent more time in close proximity to speakers broadcasting high-pitched male roars. Given that previous work on red deer failed to detect a differential response by females to playback stimuli representing different male pitch variants (McComb 1991; Charlton et al. 2008b), the current research emphasizes that experimental investigation of female choice in mammals should be conducted during the females peak conception times (for review see Charlton 2008). Differences in the behaviour of oestrous versus non-oestrous females in mate choice situations have previously been reported in fallow deer, with oestrous females displaying a strong preference that was absent in non-oestrous ones (McComb & Clutton-Brock 1994).. To our knowledge, the results presented here constitute the first evidence of a female preference based on the fundamental frequency of a male call in a non-human mammal-but crucially, in the ...
The 2013 hunting season is looking very promising because the politics of deer management is changing, starting with the House Fish and Game Committee in Harrisburg. An economic study showed that the state is making a couple of million dollars on certified timber sales each year while losing $185 million generated by hunters and other sportsmen - more than $1 billion since the Pennsylvania Game Commission and Dr. Gary Alt, the commissions deer management supervisor from 1999 to 2004, started a poorly conceived kill-the-deer management policy. That policy, which stressed habitat restoration and decreasing state herds, included multiple-doe and Deer Management Assistance Program (DMAP) permits on public land. Public land with good deer population draws hunters to rural Pennsylvania. The hunters spend money all across the state. But with a sharp decline in deer populations and fewer people hunting, The region north of Interstate 80 known as the Pennsylvania Wilds has suffered with businesses ...
Shiga toxin-producing E. coli carrying the stx1 and/or stx2 genes can cause multi-symptomatic illness in humans. A variety of terrestrial and aquatic environmental reservoirs of stx have been described. Culture based detection of microbes in deer species have found a low percentage of samples that have tested positive for Stx-producing microbes, suggesting that while deer may contain these microbes, their overall abundance in deer is low. In this study, quantitative PCR (qPCR) was utilized to test for the presence of stx genes in white-tailed deer fecal matter in western Pennsylvania. In this culture independent screening, nearly half of the samples tested positive for the stx2 gene, with a bias towards samples that were concentrated with stx2. This study, while limited in scope, suggests that deer may be a greater reservoir for stx than was previously thought.
Readers have turned up another photo documenting European fallow deer in Mariposa County.. The photo that appears with this update was posted on the GAZETTEs Facebook page on Aug. 12 by Shelly Sprague Jouett. The photo was taken by Spragues husband off Agua Fria Road this past spring.. The presence of the European deer in Mariposa County seems to be a recent development. According to a 2012 California Fish and Wildlife report, only about 500 of the deer were known to be in the entire state--most around Point Reyes National Recreation Area. Additional fallow deer have been documented in Mendocino County ...
The Iowa Department of Natural Resources is keeping a close eye on the deer population as a fatal disease spreads across the Midwest.
Argos, it is true that contraception has not yet been proven to reduce wild deer populations to the carrying capacity of the Crum Woods. There hasnt been enough interest in ecology to conduct a study like that; most communities just care about reducing deer-human conflicts. So is there a degree of uncertainty involved in this discussion? Of course. But the absence of such data does not belie the positive implications of the studies that have already been conducted. From tests on deer populations in Maryland, New Jersey, and New York, we know that the drug works: a single dose renders 80% of female deer infertile for up to 5 years, a second dose 100% for life. Over the course of 6 years, one population was reduced by over 50%, while another was reduced by 40% in 5 years. And from information that Bryon Schlisser himself provided on April 25, 2007 in Science Center 101, we know that wild deer, especially in suburban settings, live in small, fixed home ranges and have a relatively low dispersal ...

Provincial wildlife officials are concerned that a disease killing deer and elk on the prairies could soon spread into B.C.. Chronic wasting disease, a degenerative nervous system condition similar to so-called mad cow disease, has been discovered in an animal 30 kilometres southeast of Edmonton.. Thats the furthest west - by about 100 kilometres - that biologists have detected the deadly disease and the discovery intensifies concerns that infected deer may make their way to B.C.. No infected animals have been found yet in B.C. but wildlife health staff are stepping up monitoring efforts in the Peace and Kootenay regions, where deer are most at-risk.. Hunters are being asked to help by donating deer, elk and moose heads for analysis. Drop-off locations are listed at www.stopchronicwastingdisease.ca.. Anyone who encounters a sick or dead deer is urged to report it to B.C.s wildlife health program by emailing [email protected] Although chronic wasting disease is similar to bovine ...
Pathogenesis and transmission of the prion disorders (transmissible spongiform encephalopathies, TSEs) are mediated by a modified isoform of the prion protein (PrP). Prion protein gene (PRNP) alleles associated with relative susceptibility to TSE have been identified in sheep, humans and possibly elk. Comparable data have not been derived for mule deer, a species susceptible to the TSE chronic wasting disease (CWD). Initial analysis of the open reading frame (ORF) in exon 3 of the mule deer PRNP gene revealed polymorphisms in all 145 samples analyzed, with 10 potential polymorphic sites. Because 144/145 (99.3%) of the samples were heterozygous for a coding change (N/ S) at codon 138 (bp 412) and a non-coding polymorphism at bp 418, and individual deer with three or four different alleles were identified a possible gene duplication was indicated. Analysis of BAC clones containing mule deer PRNP genes revealed a full length functional gene and a processed pseudogene. The pseudogene was characteristic of

DES MOINES, Iowa - Iowa officials are planning a second special deer hunt in northeast Iowa to test the animals for chronic wasting disease.. The state hopes to collect up to 300 samples from mature deer in Clayton County, about 25 miles north of Dubuque, from Saturday through March 5, The Des Moines Register reported. The Iowa Department of Natural Resources wants hunters who will receive special scientific licenses to focus on an area about 10 miles west of Elkader.. The disease is fatal, according to Dale Garner, the DNRs conservation and recreation division chief. No human cases have ever been recorded.. Ten wild deer in neighboring Allamakee County tested positive for chronic wasting disease last year, bringing the total to 16 since 2013. Another infected deer was found during the first special collection earlier this month. A wild deer tested positive for the disease last year in Clayton County.. Both counties are popular locations for deer hunting.. The disease is caused by an abnormal ...
Now that spring is finally here and folks are venturing outdoors again, there is a certain insect that everyone should be aware of: the deer tick. Turkey hunters and anglers are especially vulnerable because they hunt and fish in ideal deer tick habitat. Sitting in the woods with your back against a tree or wading through streamside brush makes both of these outdoor enthusiasts a prime candidate for an encounter with deer ticks.. The deer tick is a tiny hard-bodied insect that can be found throughout the East and northern states of the Midwest. Not much bigger than a pinhead, it is a carrier of several diseases that can infect animals and humans alike, including Lyme disease. Whitetail deer are the primary hosts of this infectious parasite-hence the name-but it is also commonly found on mice, black bears, and wild birds, including turkeys.. Deer ticks are bloodsuckers and like mosquitoes, only the female deer tick bites and parasitizes. She has a two-year life cycle during which she goes through ...

In use since 1950s, Maines deer allocation system has worked very successfully; however, with a changing climate, changing landscapes, and perhaps, missing data for the 2 extremes of our winter weather - the very mild and the very severe - it was time for the WSI system to be re-evaluated. Kyle Ravana, the lead MDIFW deer biologist, recently initiated a 5-yr study to conduct deer population monitoring using GPS satellite collar technology to track survival and mortality trends in Maines antlerless deer - i.e. does and fawns.. The Goals of the project are to:. 1) Reevaluate the correlation between WSI and WMR for white-tailed deer. 2) Assess seasonal survival rates for the adult female (?1.5 years) and fawn segments of the population. 3) Assess cause-specific mortality of our adult female and fawn populations. 4) Reassess the current winter severity index and try to identify a new, and more simplistic metric" ,,,Read More,,,.

The genetic diversity and effective population size (Ne) of a population of Odocoileus virginianus veraecrucis in captivity were characterized in the Wildlife Management Unit
The principal aim of this study was to improve the laboratory diagnosis of inflammation in farmed red deer, primarily through the investigation of blood cells and inflammatory proteins in a variety of inflammatory conditions. The objectives were: 1) To establish solidly based reference values for haematological parameters and certain acute phase proteins, including fibrinogen, that may be useful in detecting and assessing infection in red deer. 2) To investigate various factors that might affect the results for these parameters, such information being essential for correct interpretation of test results. 3) To investigate aspects of the acute phase response in red deer. 4) To investigate changes in the above parameters in deer in a selection of infections. 5) To explore the observed responses in terms of possible functions of the components by reference to the literature. Despite a lower content of myeloperoxidase in deer leucocytes, automated leucocyte differential equipment (Technicon H6000/C) ...
The Florida Fish and Wildlife Commission (FWC) has been collecting biological data since 2009 from white-tailed deer to estimate the breeding dates for deer across the state. These data have been used to inform management decisions regarding hunting season dates and location of zonal lines. In addition, the data provides local information on peak breeding, something that is of interest to white-tail enthusiasts.. In northern deer ranges, the duration of the breeding season (or rut) is short and there is little variation from area to area. Breeding occurs in the fall, and fawning occurs in the spring. In the southeast, the timing is not as short and deer breeding activity is more variable. However, Florida has more variability in breeding than any other state -- from July in southern Florida to February in northwest Florida. During this ongoing study, FWC biologists have documented breeding to occur in every single month except May. FWC will continue to collect breeding chronology data as needed. ...
Despite of important advances in the knowledge of the reproductive biology of several deer species (mainly, red deer), there is a lot to investigate. We are trying to answer a practical and a basic question: how can we improve sperm cryopreservation in cervids? and, which underlying, cellular and molecular, changes occur during cooling and cryopreservation?. These are important questions not only for our Iberian deer species (Iberian red deer and roe deer), but also to endangered cervids elsewhere in the world (specially South-American species such as the huemul and pudu). Technology transfer from well-known species to related but less studied species might improve their conservation.. ...
The changes address containment and surveillance measures, and permitted movement of live deer, in portions of Bandera, Medina, and Uvalde counties as well as zone delineations in the northwest Panhandle.. Last year, the Commission established a CWD Surveillance Zone (SZ) in portions of Bandera, Medina, and Uvalde counties as a result of CWD being confirmed in permitted deer breeding facilities in the area. A containment Zone (CZ) was not established in this area because the disease had been detected only in permitted deer breeding facilities or their adjacent release sites, all of which had been issued hold orders or quarantines by Texas Animal Health Commission; these measures included requirements that satisfied the need for a CZ. This particular SZ was exempted from mandatory sampling and carcass movement restrictions in lieu of a local voluntary hunter and landowner effort to submit samples.. However, CWD was subsequently detected in a free-ranging white-tailed deer within that SZ, which ...
The adult arterial nematode worm lives primarily in the deers carotid arteries. High worm infestations reduce blood flow, which causes partial paralysis of the deers jaw muscles. Food becomes impacted inside the deers mouth due to the jaw muscle paralysis. The food impaction causes the "lumpy jaw" appearance. The common horsefly passes the nematode larvae from an infected deer to an uninfected one by feeding on deer blood. Infection rates are not high enough to impact deer populations and no human health implication has been reported. ...
One can see a herd of 10-20 deer roaming in the fields and meadows," L Krishnamurthy, field director of KNPTR, who has worked for the deers conservation, said. Swam deer are already extinct in Pakistan and Bangladesh. It is now found only in south- western Nepal and central and northeastern India. There are three subspecies of swamp deer found in the Indian Subcontinent. The western swamp deer (Rucervus duvaucelii) found in Nepal, southern swamp deer (Rucervus duvaucelii branderi) found in central and north India and eastern swamp deer (Rucervus duvaucelii ranjitsinhi) found in the Kaziranga and Dudhwa National Parks.. ...

Preserving the health of white-tailed deer populations is a top priority for state and federal resource agencies because of their role in maintaining healthy ecosystems, preserving our hunting heritage, and providing a stable source of wildlife funding. The emergence of chronic wasting disease (CWD) in free-ranging cervid populations threatens the sustainable future of white-tailed deer because long-term population declines are associated with this disease. This project aims to develop scientifically-based surveillance and monitoring techniques through risk-based assessments of human and wildlife factors associated with CWD outbreaks. Using data from CWD-endemic areas provides valuable insight into how CWD spreads on the landscape and why the disease can show sporadic distribution. The ultimate goal of the project is to identify and remove diseased animals quickly before CWD becomes well-established ...

The largest population is located in the Royal National Park (RNP), New South Wales, Australia. Although the deer are considered a pest in certain areas, they are also commercially valuable. Using molecular markers we aimed to characterise the level of genetic diversity within the RNP population and identify a possible genetic bottleneck associated with the introduction of seven founding individuals. We also aimed to identify appropriate polymorphic microsatellite loci that could assist in commercial breeding programmes and wild population management in Australia. The results indicate that Javan rusa deer from the RNP (n = 37) had an average (± SE) of only 2.29 ± 0.095 ...
Reproductive control in wildlife management has been assessed for several decades across multiple species. Its use has gained more attention as the public has become more interested in wildlife management decisions. For reproductive control agents to effectively reduce deer population size, they must decrease the reproductive rate to less than the mortality rate. In urban deer populations, mortality rates are generally very low (approximately 10%). Also, to control the growth of the deer population, it is necessary to treat 70%-90% of the female deer with a highly effective product to successfully reduce or halt population growth in a closed population without immigration or emigration (Rudolph, Porter, and Underwood 2000; Hobbs, Bowden, and Baker 2000). The science and understanding of fertility control are evolving. The most updated information about fertility control is summarized in appendix D. The terms fertility control and reproductive control are used synonymously in this ...

If you had to pick buying the most premium deer decoys, the most premium deer calls, or the most premium deer urine, you should prioritize buying premium deer urine (and were not just making that up because were a deer urine company!). The fact is, deer urine is the closest attractant to a real deer as it actually co
Epizootic hemorrhagic disease (EHD) is a hemorrhagic disease caused by a virus. EHD is similar to bluetongue, another viral disease that can affect deer. It spreads from deer to deer by the bite of a small insect known as a midge. The disease quickly kills the deer through hemorrhaging within the body. A high fever may result, causing the deer to seek water to cool off. Dead deer usually are found in or near water. Deer may show bleeding from body openings, although they usually are in good body condition because of the quickness of the disease. EHD is not a threat to humans ...
The April issue of the newsletter of the Maine Woodland Owners includes an important article on deer, ticks, and Lyme disease, written by Peter Rand, MD, and Charles Lubelczyk, Vector Ecologist. The writers are associated with the Vector-borne Disease Laboratory of the Maine Medical Center Research Institute in Scarborough.. Among the interesting information presented was this sobering conclusion: "As unpopular as it may be, deer control by lethal means remains a primary tool in what should be an integrated approach to reducing the threat. Where deer can be excluded or maintained well below 10 per square mile, little else may be needed to control deer ticks.". I encourage you to read this entire article. We all need to know more about deer ticks and Lyme disease, particularly because this is a significant issue as a new 15-year deer management plan is created.. MWO Article. Last year, despite the summer drought that should have depleted their numbers, deer ticks, which are now transmitting the ...
