“…According to Stoufflet and Caillol (1988), in early pregnancy females are hardly receptive to males and this would increase male activity for mating. Similar values have been reported in other lagomorphs such as the cottontail rabbit (Sylvilagus floridanus) (Trent and Rongstad, 1974). In contrast, a marked reduction in activity was observed from April to October, which could be attributed to the changes in environmental conditions and decreased food and water availability, though both requirements were provided ad libitum (Boyd, 1986;Boag, 1992;Eiserman et al, 1993;Ballinger and Morgan, 2002).…”

The activity of 2 populations of wild rabbits (Oryctolagus cuniculus, L. 1758), consisting of 14 adults (>9 mo of age) each (4 males and 10 females), was analysed over 2 consecutive years. Rabbits were captured in the wild and kept in 2 separate enclosures of 0.5 ha, with each enclosure divided into 2 zones: a smaller area where warrens were located (breeding area) and a larger area where food and water were provided (feeding area). Seven rabbits in each enclosure were individually tagged with a microchip (2 males and 5 females) and, after installing 2 detection devices, it was possible to identify which of the 2 areas they were located in and record the length of time spent in each. To regulate the size of the breeding population, young rabbits produced in the enclosures were captured and removed regularly. Considering the number of movements between areas and the time spent in the feeding area, a circadian activity pattern was found, reporting 2 maximum activity peaks coinciding with twilight (18.35% of the total movements, 6-8 a.m.) and daybreak (22.95%, 7-10 p.m.) while activity was dramatically decreased during the midday hours (1.86%, 10 a.m.-4 p.m.). Rabbits displayed a seasonal pattern throughout the year, with maximum activity levels during winter (45.76% of the total movements, January-March) and spring (42.91%, April-June), which could be related to higher reproductive activity at this time of the year as a higher breeding output was reported in June and September. The levels of activity exhibited by males (13.44% daily activity rate) were significantly higher than those displayed by females (9.80%). No significant differences were found regarding time spent on the feeding area in relation to season or gender. The average duration of each foray to the feeding area was higher during the summer, higher for females than males and higher during the middle of the night than the rest of the day.

“…We examined the percentage of pups surviving to 5 months of age as a measure of reproductive success (at 5 months the pups were independent of parental care and recruited into the population). We calculated annual survival rates, using MICROMORT (Heisey and Fuller 1985), for the various cohorts by extrapolating daily survival rates (Trent and Rongstad 1974) using animals of known fate. Dispersal rates were estimated similarly to survival rates but substituting dispersal for death in the calculation (Fuller 1989).…”

Territorial defense and maintenance are an important facet of the social ecology of most carnivore species. From January 1991 to June 1993, we observed 54 coyotes (Canis latrans) for 2507 h in Yellowstone National Park, Wyoming, during which we observed 112 instances of territory defense. The identity of the coyotes involved in challenging and evicting intruding animals was known. Alpha coyotes were most likely to be involved in territorial evictions of intruding animals, followed by beta individuals; pups participated little in territory defense. Coyotes evicting intruders generally had a numerical advantage when challenging the intruders. Territory-defense rates were highest during and immediately after the breeding season and during the time of pup emergence from the den. All chases of intruders ended at the boundary of the resident coyote pack's territory. Physical contact between the intruding animal and resident pack members occurred with no intruders being killed or seriously injured. Physical contact consisted of fighting and ritualized behaviors, with only a few instances in which fighting led to blood being drawn or minor injuries to the intruder. Most encounters resulted in a hasty retreat from the area by the intruder(s). While indirect means of territory maintenance (i.e., howling and scent-marking) were utilized by resident packs, trespassing still occurred and direct confrontation was needed to enforce boundaries and assert occupancy against other resident packs, as well as against lone intruders seeking territory vacancies. Territoriality was advantageous in that territory holders generally had higher survival rates (except pups), contributed all the reproductive effort to the population, and had greater access to food resources. In contrast, nonterritorial animals had lower survival rates, did not breed, and had reduced access to food (ungulate carcasses) during winter.Résumé : La défense et la conservation du territoire constituent une facette importante de l'écologie sociale de la plupart des espèces de carnivores. De janvier 1991 à juin 1993, nous avons observé 54 coyotes (Canis latrans) pendant 2507 h dans le parc national de Yellowstone, au Wyoming, au cours desquelles nous avons étudié 112 cas de défense de territoire. Les coyotes qui ont défié et chassé des intrus de leur territoire ont été identifiés. Les coyotes alpha sont plus enclins à évincer les intrus de leur territoire, suivis des coyotes bêta; les petits participent peu à la défense territoriale. Les coyotes qui évincent des intrus ont généralement l'avantage numérique lorsqu'ils les poursuivent. La fré-quence des cas de défense territoriale est maximale pendant et immédiatement après la saison de reproduction et au moment de la sortie des petits des terriers. Toutes les poursuites observées ont pris fin à la frontière du territoire de la meute résidante. Les contacts physiques entre intrus et résidants de la meute n'ont jamais abouti à la mort d'un intrus, ni même à des blessures graves. Les contacts physiques se limit...

Once found throughout the Rocky Mountains and forests of the northern states, the lynx now hides in pockets of its former range while feeding mostly on small animals like snowshoe hares. A team of government and university scientists review the newest scientific knowledge of this unique cat's history, distribution, and ecology. The chapters on this web site provide information for current scientific and public debates regarding the fate of the lynx in the United States. Chapters look at the relationships among lynx, its habitat, and its prey. The attributes of northern versus southern lynx populations are compared and contrasted. The authors caution against making decisions without enough knowledge and show where we lack information. While the authors present the latest preliminary research results on lynx and offer some qualified insights into lynx management, the book's intent is to assess the current state of knowledge regarding lynx.Hard copies of the report will be available in late 1999 from the University Press of Colorado,
