(M.A., Applied Geography) Predictive ecological modeling of grey wolf (Canis lupus) movement using agent-based modeling and GIS Thesis directed by Associate Professor Steve Jennings, Emeritus ABSTRACT There is a wide-spread loss of large predators being witnessed across ecosystems globally. The large, apex predators are either displaced from habitat destruction, or killed directly by anthropogenic disturbances. We need apex predators for tri-trophic cascades, mesopredator control, and to promote biodiversity in ecosystems. Previous ecology research highlights how a tri-trophic cascade, or a series of dynamic interactions between predator, prey, and vegetation, is vital for allowing the ecosystem to be resilient and sustainable to disturbances. Technology equips us with new methods of exploring ecosystem functions, animal behavior, and how changing landscapes affect animal movement. By constructing an ABM for grey wolves in North America, we experimented with different predator efficiencies to test how grey wolves could possibly recolonize Moffat County, Colorado. Results from the ABM showed patterns of wolf occupation along low-elevation, river valleys, the wolves did not impact or disrupt prey population demographics, and wolves were able to recolonize the region despite the different predator efficiencies.

    Dissertation 2011-2012 Vanessa Almeida da Silva Amorim Wolf V Dog – Predator V Pet 4 BDAO Titel Predator V Pet – the difference between wolves and dogs Abstract Dogs play a prominent role in modern day society. Most of them are kept for companionship which translates into a very close dog-human relationship. Canis familiaris have adapted incredibly well to man-made society however with an increasing number of cases ending up in shelters it is fair to say that this subject still needs further exploration. A lot has been written about the way dogs behave and how owners can improve their relationship with their pet. A very popular vision on dog behaviour is the wolf pack theory also called lupomorphism. For a long time the interpretation of this vision consisted in the need for a dog owner to be a leader by any means. If an owner is not strong enough as a leader a dog will try to take over this role and show behaviour that is not desirable. Recent studies have shown that there are gaps in this theory. The vision on how a wolf pack functions has changed and there is an increasing number of experts that agree that the best study subject for dog behaviour is in fact the dog itself. The goal of this thesis is to clarify how dogs and wolves relate to each other as species both biologically and psychologically. A lot of literature research has gone into this thesis to try and find out what really goes on inside a dog’s head and if comparing them to wolves is useful to grasp that idea.

  • To Howl Or Not to Howl? the Nature of Synchrony in Wolf Chorus Howling
    To Howl or not to Howl? The Nature of Synchrony in Wolf Chorus Howling Rebecca Barrett Abstract As apex predators, grey wolves (Canis lupus) are in direct conflict with humans and have been historically persecuted due to livestock depredation. Their numbers fell dramatically in the 20th century but following reintroduction and the establishment of a protected status, wolves are recolonizing many areas of their historical range. Effective wild management schemes are necessary to minimise further human-wolf conflict. To develop effective management schemes, a more complete understanding of wolf vocal behaviour is needed. The recording of wolf howls could provide a non-invasive method to monitor population sizes and territories in the wild. Wolf howls are used for long range communication and play a role in territory maintenance and pack assembly. Chorus howls are thought to have similar functions. In this study we recorded howls of captive wolves to investigate the structure of choruses and elucidate whether this is related to individual wolf characteristics such as howl frequency, age, sex or dominance rank. We found that while some individuals led more chorus howls than others, the initiation success of each wolf was equal. Chorus leadership does not appear to be dominated by specific individuals or determined by specific howl characteristics. Instead, the leading of choruses appears to be a by-product of increased howling rate and duration. These results improve our understanding of wolf chorus howls and could prove useful in the development of monitoring schemes and long-range pack identification in the wild. 1 Introduction Acoustic signals play an important role in animal communication by allowing messages to be conveyed rapidly over long distances without the need for physical or visual contact (Hopp et al.

  • Wolves, by the Numbers Larry Desjardin
    Wolves, by the Numbers Larry Desjardin In November 2020, Colorado citizens will vote on Proposition 114, the Gray Wolf Reintroduction Initiative. It would mandate Colorado Parks and Wildlife (CPW) to develop a plan to reintroduce gray wolves onto lands west of the Continental Divide by 2023. There has been much debate on what impact wolves would have on Colorado ungulate herds, ranching, and hunting. Much of the debate has been qualitative in nature- citing advantages and disadvantages of wolves on the landscape. This paper describes a wolf/prey simulator that quantitatively models the impacts of wolves on Colorado ungulates (specifically elk, deer, and moose) and the associated changes in hunting to maintain stable herd sizes. The results are compared to documented observations and studies of wolves reintroduced into Yellowstone National Park. This paper also looks at livestock depredation impacts, modeled by the historical record in Montana. The conclusion of the analysis is that the impact from wolves is highly correlated to their total population. Wolf/Prey Simulator A wolf/prey simulator was developed combining a yield analysis of each ungulate species together with a biomass consumption model for wolves. The simulator has two distinct pieces to it: The simulation engine itself, and the biological and herd parameters that it simulates. For any one scenario (the set of biological parameters) the number of wolves may be varied to model the impact. The simulator comes with default parameters that describe the standard model. Any of these parameters may be modified by a user. To test the credibility of the simulator, the results of the standard model are compared to observed elk consumption by wolves from numerous studies.

The use of olfactory enrichment can improve captive welfare of mammals and has a variety of applications in captive animal management. This study explores the effects of 3 aromatherapy scents (tangerine, peppermint and rosemary) as olfactory enrichment on 5 key behaviours of 4 captive grey wolves housed at the UK Wolf Conservation Trust. The wolves were exposed to each of the scents repeatedly over a period of weeks. Behavioural observations were made every day and scents administered twice a week. The scent was administered via a dilute solution poured over a straw bail.
