Social, Spacing, And Cooperative Behavior Of The Collared Peccary, Tayassu Tajacu, John A. Byers, Marc Bekoff
Social, Spacing, And Cooperative Behavior Of The Collared Peccary, Tayassu Tajacu, John A. Byers, Marc Bekoff
Ethology Collection
Social behavior of the collared peccary was studied on the lower, eastern slopes of the Mazatzal Mountains, Arizona. The social unit in this species is a cohesive herd, in which small inter-individual distances are maintained. Two conspicuous acts, one olfactory and one auditory, functioned to maintain close spacing. Social interactions were brief but tended to synchronize the activities of animals and also to bring them closer together. Amicable and neutral actions occurred far more frequently than agonistic interactions. Most agonistic behavior did not involve physical contact. Cooperative nursing, predator defense, and feeding occurred; all adults were tolerant of young, and …
Activity Of Moose And White-Tailed Deer At Mineral Springs, D. Fraser, H. Hristienko
Activity Of Moose And White-Tailed Deer At Mineral Springs, D. Fraser, H. Hristienko
Social Behavior Collection
Activity of moose (Alces alces) and white-tailed deer (Odocoileus virginianus) was studied at two natural mineral springs (licks) in Ontario during the springtime and summer of 1977 to 1980. Most adult moose appeared to use a lick during a single 1- to 5-day period in a year; some returned at intervals during the season; and all seemed drawn principally by the mineral-rich water. Some young moose remained in the lick vicinity for 3 weeks or more, and often wandered in and out of the licks, grazing herbage as well as drinking. This suggested a social as well as a nutritional …
Behavioural Budgeting By Wild Coyotes: The Influence Of Food Resources And Social Organization, Marc Bekoff, Michael C. Wells
Behavioural Budgeting By Wild Coyotes: The Influence Of Food Resources And Social Organization, Marc Bekoff, Michael C. Wells
Ethology Collection
Daytime behavioural budgets of coyotes (Canis latrans) living in the Grand Teton National Park Jackson, Wyoming, were analysed in order to determine how activity patterns ' ere influenced by food resources and social organization. In winter coyotes rested more-and hunted less than in other seasons. Pack-living coyotes rested more and travelled less than resident pairs or solitary resident or transients during winter months when the major food resource was ungulate (predominantly elk, Cervus canadensis) carrion. A mated female living in a pack rested significantly more and travelled significantly less than a mated female living only with her mate (as a …
An Observational Study Of Coyote (Canis Latrans) Scent-Marking And Territoriality In Yellowstone National Park, Joseph J. Allen, Marc Bekoff, Robert L. Crabtree
An Observational Study Of Coyote (Canis Latrans) Scent-Marking And Territoriality In Yellowstone National Park, Joseph J. Allen, Marc Bekoff, Robert L. Crabtree
Ethology Collection
Free-ranging coyotes (Canis latrans) living in neighboring packs were observed in the Lamar Valley of Yellowstone National Park, Wyoming, from Jan. to May 1997. Through direct observation, we recorded the location of coyote scent marks and information regarding the identity of the marking animal. Patterns of scent-marking were then analyzed spatially and demographically. All of the evidence from the present study supports a strong relationship between scent-marking and territoriality in these coyotes, and all predictions were met. A preponderance of scent marks was found in the periphery of territories. Most of those marks were raised-leg urinations (RLUs) and forward-lean urinations …
An Observational Study Of Scent-Marking In Coyotes, Canis Latrans, Michael C. Wells, Marc Bekoff
An Observational Study Of Scent-Marking In Coyotes, Canis Latrans, Michael C. Wells, Marc Bekoff
Ethology Collection
Urination and defaecation patterns of free-ranging coyotes (Canis latrans) were studied in the Grand Teton National Park, Jackson, Wyoming, for two years. The vast majority of urinations by adult males and females were involved in 'marking,' and differentiating between 'marking' and 'elimination' may not be necessary. Our results may be summarized as follows: 1) Raised-leg urinations (RLU) performed by males were most frequently used in marking. (2) Females marked throughout the year using the squat (SQU) posture. (3) Snow tracking and reading snow sign resulted in a gross underestimate of the relative frequency of SQU's and a large overestimate in …
Equine Behavior Problems In Relation To Humane Management, Katherine A. Houpt
Equine Behavior Problems In Relation To Humane Management, Katherine A. Houpt
Equines Collection
The behavior problems of horses are frequently related to management practices. Behaviors that are termed stall vices appear to be either stereotyped behaviors that occur in reaction to stress, or patterns that emerge when natural behaviors such as grazing are prevented. The behavior cases presented to the New York State College of Veterinary Medicine, Cornell University, were tabulated: 27% were stall vices and 27% were some form of aggression. The stall vices were circling, digging, kicking the stall, chewing wood, swallowing air or self-mutilation. Management of horses on pasture rather than in stalls prevents the development of many of these …
The Metaphysics Of Anthropocentrism: A Review Of Paul Ehrenfeld's "The Arrogance Of Humanism" And Mary Midgley's "Beast And Man", Bernard E. Rollin
The Metaphysics Of Anthropocentrism: A Review Of Paul Ehrenfeld's "The Arrogance Of Humanism" And Mary Midgley's "Beast And Man", Bernard E. Rollin
Attitudes Towards Animals Collection
Our attitudes and behavior toward nature and toward other forms of life are clearly in the forefront of contemporary ethical concern. It thus becomes necessary to examine critically the metaphysics which has traditionally grounded these attitudes. Unquestionably, the key feature of the dominant underlying conceptual scheme has been the positing of a clear-cut dichotomy between man and the natural world. For most of the Greeks, man is radically separated from nature- he lives in the realm of nomos, convention, somehow above the realm of physis, nature. He can reason, communicate, choose, create a social order, apprehend ultimate reality, and even …
Where To Put Your Choker, Roger A. Mugford
Where To Put Your Choker, Roger A. Mugford
Pets Collection
The choke chain has come to be regarded as an indispensable aid to training dogs, but even the most time-hallowed practices deserve an occasional critical review. The author has recently completed an investigation into the uses and abuses of choke chains, and failed to find any benefit from using a choker rather than a conventional leather collar. Indeed, there are some very considerable dangers and disadvantages associated with the device. These charges may sound like heresy to many dog-trainers, but to others, it may strike a sympathetic chord.
The Buller-Steer Syndrome, Richard Ulbrich
The Buller-Steer Syndrome, Richard Ulbrich
Ethology Collection
Bulling among steers is an abnormal behavioral trait and is a common health and economic problem in feedlot operations. Factors associated with the buller-steer syndrome are hormonal implantation, seasonality and environmental conditions, stress, overcrowding, and social interaction between individuals. Research has examined relationships between these and other factors and buller occurrence. Boredom of feedlot cattle may contribute to buller occurrence and other undesirable behavior more than we might suspect. Research is needed to determine the feasibility of enriching the environment of penned livestock in general, the goal of which would be, in theory, the elimination of undesirable behavior as well …
Social And Cognitive Capabilities Of Nonhuman Primates: Lessons From The Wild To Captivity, William C. Mcgrew
Social And Cognitive Capabilities Of Nonhuman Primates: Lessons From The Wild To Captivity, William C. Mcgrew
Sentience Collection
All anthropoid primates in nature lead highly sociable lives. In infancy and childhood this is characterized by stability and familiarity for both sexes; in adulthood either one or the other sex changes groups. The natal group provides a social network of matrilineal kinship; after sexual maturity incest avoidance and exogamy are the rule. Important differences exist across species and between the sexes in mating strategies. In most species, males emigrate, but in others females do so. Male sexual behavior is based on competition between peers; females exercise choice in selecting sexual partners. Normal development of sexual behavior and maternal caretaking …
Abnormal Behavior As An Indication Of Immaterial Suffering, Hans Hinrich Sambraus
Abnormal Behavior As An Indication Of Immaterial Suffering, Hans Hinrich Sambraus
Sentience Collection
Reactive abnormal behavior is the convincing proof of immaterial suffering for the ethologist. We consider abnormal that behavior which does not correspond to, or is without object, which appears with sharply increased or decreased frequency, or which is abnormal in its motor pattern. Moreover, much reactive abnormal behavior manifests itself in stereotypies, i.e., the movement is repeated continuously in the same way. Among wild animals and in traditional forms of animal production abnormal behavior is unknown. However, it is encountered often in animals in intensive husbandry systems, and it can be demonstrated that abnormal behavior is actually brought about by …
