Multiple Mates Worth the Risk for Female Prairie Dogs

December 4, 2013 by PDP

Dec. 4, 2013 — Mating with more than one male increases reproductive success for female prairie dogs, despite an increase in risks. This is according to a new study published in The Journal of Mammalogy by behavioral ecologist John Hoogland, Professor at the University of Maryland Center for Environmental Science’s Appalachian Laboratory.

Gunnison’s Prairie Dogs

September 11, 2010 by PDP


Description: Yellowish buff mixed with black above, slightly paler below. Short, white-tipped tail. Terminal half of tail grayish white in center. 12-14″ in height, weighing 23-42 ounces. Lives 3-5 years in the wild, longer in captivity.

Similar Species: White-tailed and Utah prairie dogs have white in center of tail rather than grayish. Black-tailed Prairie Dog’s tail has black tip.

Breeding: 1 litter per year of 1–8 young, born in early May; gestation 27–33 days, pups emerge mid June.

Habitat: Short grass prairies in high mountain valleys and plateaus of southern Rocky Mountains at elevations of 6,000–12,000’ (1,800–3,600 m). Habitat is much more variable topographically and vegetationally than that of the Black-tailed Prairie Dog, which occurs at lower elevations.

Range: Southeastern Utah, south and central Colorado, northeast and central Arizona, and northwest New Mexico.

Discussion: The Gunnison’s Prairie Dog, like the rest of its kin, is active only when the sun is up, and is most energetic near dawn and dusk. It is constantly vigilant while aboveground, often sitting upright on its hind feet while it pursues its main activities: mainly feeding, but also grooming and playing. This animal generally is seen from April to October. It hibernates (torpor) in winter, living on stored body fat. It usually emerges in April, though they will emerge earlier if the winter is mild. Gunnison’s Prairie Dog feeds on green vegetation, particularly grasses, but also forbs, sedges, and shrubs, as well as a few insects. Its colonies are generally smaller and less closely knit than those of other prairie dogs, resembling ground squirrel aggregations, with fewer than 50 to 100 individuals. The animals in the colony cannot always see one another because their habitat is in such varied and patchy terrain, which is caused in part by human activities. On flat ground and where this prairie dog is protected colonies are much larger and more extensive. This species’ burrow systems can be up to 80 feet long and 16 feet deep in well-established colonies. Burrows can have food storage, flood, nesting, communal and excrement chambers. Territoriality is not well developed in Gunnison’s Prairie Dog, although old males may defend small areas outside their burrows. Mother-young relationships form the basic social unit. Newborns remain in the burrow about three weeks before emerging and are weaned about three weeks later. The female sits almost straight up on her haunches to nurse her young, who suckle either pectoral or inguinal (hind leg) nipples. Gunnison’s alarm call, distinctive among prairie dogs, is important to the survival and structure of the community. It is a series of high-pitched barks of one or two distinct syllables, with the second syllable lower and more guttural. The call may be repeated frequently and may continue for as long as half an hour. It increases in intensity as danger escalates, and ends in chatter as the animal enters its burrow. Predators include American Badgers, Coyotes, weasels, and raptors. Plague (Yersina pestis), carried by fleas, can decimate populations of this species. However, humans, through their extermination programs, are the chief enemy of Gunnison’s Prairie Dog.

Prairie Dog Facts

September 11, 2010 by PDP

  • Two of the five species of prairie dogs are protected under The Endangered Species Act. Black-tailed prairie dogs have been granted a “Warranted but Precluded” Threatened Species listing, which means that biologically they deserve protection but the government does not have the resources required for enforcement at this time.
  • Overall, prairie dogs inhabit less than 1% of their former range. New Mexico has the smallest remaining acreage of prairie dogs across their historical range. Best estimates on Gunnison’s populations are that they inhabit about 2% of their former region. This means overall numbers are dangerously low since their range is much smaller than that of the Black-tailed Prairie Dog. A surprisingly large percentage of remaining prairie dog colonies live in urban environments.
  • Black Footed FerretsPrairie dogs are known as a “keystone species.” Over 160 vertebrates alone are associated with large prairie dog colonies and over 80 on “urban” colonies. Possibly the world’s most endangered animal, the Black-footed Ferret, cannot live without prairie dogs. Some other federally protected species are nearly as dependent including the Ferruginous Hawk, the Burrowing Owl, the Swift Fox and the Mountain Plover. Biologists have termed them “perhaps the most important mammal on earth.”

Prairie dogs are important to their environment in three ways:

  • They are the primary prey on rangelands and their colonies also provide a greater density of other prey species.
  • They provide homes or shelters for dozens of species.
  • Their positive effect on soil and vegetation conditions.

 

  • Prairie dogs are annual breeders. About half of the females over two years of age will give birth to 3-5 pups in the spring. The overwhelming majority will not live six months.
  • Prairie dogs are highly social and possess the most complex language of any animal ever studied. They display different calls for raptors, coyotes, humans and even humans carrying guns. They have numerous other calls totaling over fifty distinct “words.” Kissing, hugging and grooming are regular pastimes. Burrows are much like homes possessing front and back doors, toilets, listening posts, sleeping quarters and storage rooms.
  • Poisoning prairie dogs is unacceptable. The primary poison used induces a slow, painful death that may take up to 72 hours. Other residents of their burrows suffer the same fate. Poisoning for population control is counter-productive. A mature colony left alone tends to expand about 2% per year. A poisoned colony expands at the rate of about 70% per year. Left to their own devices, prairie dogs experience their own natural population declines. They never undergo these decreases if we are constantly inducing our own, unnatural removal on their colonies.
  • Shooting definitely has a significant impact on prairie dog populations. One heavily shot area was reduced by 10,000 acres in just a couple of years. Shooting promotes disease, discourages other species from hunting or living in the colony, and is not “hunting.”

Prairie Dog Talking Points

September 11, 2010 by PDP

  • Prairie dogs are a keystone species with up to 205 associated vertebrates (9 considered dependent) living with them, using their burrows, or predating upon them
  • There are 5 species of prairie dogs. The ones in Albuquerque are Gunnison’s, the others include Mexican, Utah, white and black tailed.
  • Gunnison’s prairie dogs hibernate during the winter months.
  • Over the last 100 years prairie dogs have been reduced to 1% of their former range and 2% of their population.
  • Some of the species are listed under the Endangered Species Act. Others are being considered for listing.
  • New Mexico has the smallest remaining acreage of prairie dogs.
  • Prairie dogs are territorial and will remain in or near their ancestral habitat if at all possible. The prairie dogs you see here in Albuquerque are the remnants of vast prairie dog towns that existed for hundreds of years.
  • Prairie dogs live an average of 3-5 years in the wild.
  • Prairie dogs are annual breeders. 50% of females over 2 years of age will breed and produce an average of 4 pups.
  • Pups are usually born in early May and will emerge from their burrows after about thirty days.
  • Prairie dogs have the most complex language of any animal ever studied.
  • They have over 200 words and can form sentences identifying intruders by color, size and type of risk.
  • Burrows are complex with a different area for each function of life. There are living chambers, sleeping and nesting rooms, a food storage area,
  • toilet rooms, and flood chambers. The burrows themselves generally include a second entrance or escape way, air chambers, and listening posts in addition to the main entrance.
  • As with humans, prairie dogs are the victims of plague. Virus carrying fleas are brought into the colony by wild animals or off leash cats or dogs.
  • As they have no immunity to the plague they will die within days.
  • Poisoning prairie dogs in both cruel and ineffective. The poison causes a slow agonizing death that may take up to three days.
  • A mature colony tends to expand at approximately 2% annually. A poisoned colony can expand at an annual rate of 70%. Additionally the poison can pose a danger to humans, cats, dogs, and other animals in the area.
