In this first comprehensive synthesis of the literature on food hoarding in animals, Stephen B. Vander Wall discusses how animals store food, they use and affects individual fitness, why evolved, cached is lost, mechanisms for protecting recovering physiological behavioral factors that influence hoarding, impact have plant populations dispersal. He then provides detailed coverage behavior across taxa-mammals, birds, arthropods-to address issues evolution, ecology, behavior. Drawings,...

Abstract Roads present formidable barriers to dispersal. We examine movements of two highly mobile carnivores across the Ventura Freeway near Los Angeles, one busiest highways in United States. The species, bobcats and coyotes, can disappear from habitats isolated fragmented by roads, their ability disperse tests limits vertebrates overcome anthropogenic obstacles. combine radio‐telemetry data genetically based assignments identify individuals that have crossed freeway. Although freeway is a...
Methods are presented for estimating survival and cause-specific mortality rates from radiomarked animals. Time is partitioned into intervals during which the daily assumed to be constant. The estimated number of transmitter-days, mortalities due particular causes, days in time intervals. Potential biases arising combining data several individuals marked at different times within an interval or identified. Variances confidence estimators presented. Hypothesis testing sample-size...
Abstract: Urbanization and habitat fragmentation are major threats to wildlife populations, especially mammalian carnivores. We studied the ecology behavior of bobcats ( Lynx rufus ) coyotes Canis latrans relative development in a fragmented landscape southern California from 1996 2000. captured radiocollared 50 86 coyotes, determined home ranges for 35 40 measured their exposure “urban association” as percentage each range composed developed or modified areas. Both species occupied...
The status of many carnivore populations is growing concern to scientists and conservationists, making the need for data pertaining distribution, abundance, habitat use ever more pressing. Recent developments in noninvasive research techniques - those that minimize disturbance animal being studied have resulted a greatly expanded toolbox wildlife practitioner.Presented straightforward readable style, Noninvasive Survey Methods Carnivores comprehensive guide researchers who seek conduct...
To evaluate whether the abundance of eoyotes Canis latrans was influenced by availability anthropogenic foods in a humanized landscape. we compared three neighboring areas (hereafter referred to as NA. CA. and SA) under contrasting human pressures within Santa Monica Mountains California. USA. We quantified use anthropegenic coyotes assessed local densities these regions. Overall. 76 coyote feces were analyzed: identified food items categorized into 11 lypes (7 native 4 anthropogenic)....
ABSTRACT Several potential proximate causes may be implicated in a recent (post-1984) decline moose (Alces alces andersoni) numbers at their southern range periphery northwest Minnesota, USA. These include deleterious effects of infectious pathogens, some which are associated with white-tailed deer (Odocoileus virginianus), negative climate change, increased food competition or moose, legal illegal hunting, and predation by gray wolves (Canis lupus) black bears (Ursus americanus)....
Summary Temporal variability in habitat suitability has important conservation and ecological implications. In grasslands, changes resource availability can occur at broad spatial scales enlarge area requirements of ungulate populations, which increases their vulnerability to loss fragmentation. Understanding predicting these dynamics, although critical, received little attention so far. We investigated dynamics for Mongolian gazelles ( Procapra gutturosa Pallas) the eastern steppes...
Aim To demonstrate how the interrelations of individual movements form large-scale population-level movement patterns and these are associated with underlying landscape dynamics by comparing ungulate across species. Locations Arctic tundra in Alaska Canada, temperate forests Massachusetts, Patagonian Steppes Argentina, Eastern Mongolia. Methods We used relocation data from four species (barren-ground caribou, Mongolian gazelle, guanaco moose) to examine interrelation among individuals....
To evaluate whether the abundance of coyotes Canis latrans was influenced by availability anthropogenic foods in a humanized landscape, we compared three neighboring areas (hereafter referred to as NA, CA, and SA) under contrasting human pressures within Santa Monica Mountains California, USA. We quantified use assessed local densities these regions. Overall, 761 coyote feces were analyzed; identified food items categorized into 11 types (7 native 4 anthropogenic). Though small mammals...
Large carnivores are of vital importance to the stability and integrity most ecosystems, but recent declines in free-ranging populations have highlighted potentially devastating effect infectious diseases on their conservation. We reviewed literature 34 large (maximum body mass adults >20 kg) terrestrial carnivore species, 18 which considered be threatened wild, examined reports antibody prevalence (seroprevalence) cases infection, mortality population decline. Of 52 examined, 44% were...
Summary A pack of 17–43 African wild dogs living in southwestern Kenya was located on 55 days during January 1988‐June 1989 when it ranged over at least 650 km 2 . During mid‐July to mid‐August the monitored daily and 250 , travelling an average 10 per day. Dogs killed most often just before or within hours after sunrise 1 hour sunset. After started hunting they generally travelled 1–2 about 30 minutes killed. Thomson's gazelle were (67% 60 kills), their biomass (48% total) equal combined...
In discussions about the relative rate of molecular evolution, intraspecific variability in is rarely considered. An underlying assumption that sequence differences are small, and thus variations would be difficult to detect or not affect comparisons among distantly related taxa. However, several studies on mammalian mitochondrial DNA (mtDNA) have revealed considerable divergence. this report, we test for evolution by comparing mtDNA sequences, as inferred from restriction site polymorphisms...
Abstract Hybridization presents a unique challenge for conservation biologists and managers. While hybridization is an important evolutionary process, also threat formany native species. The endangered species recovery effort the red wolf Canis rufus classic system understanding addressing challenges of hybridization. From 1987?1993, 63 wolves were released from captivity in eastern North Carolina, USA, to establish free-ranging, non-essential experimental population. By 1999, managers...
Wolf (Canis lupus) activity and interactions with white-tailed deer (Odocoileus virginianus) were monitored in north central Minnesota during six winters which mean January–February snow depth alternated between shallow (19–26 cm) relatively deep (40–47 (winter severity index; L. J. Verme. 1968. Wildl. Manage. 32: 566–574) mild (71–98) moderately severe (126–137). Wolves traveled farther more often spent less time other pack members than winters. Radio-marked wolves used conifer cover less,...
Serum samples from 76 free-ranging adult jackals of three species four localities in Kenya were examined for circulating antibodies against canine pathogens: rabies virus, parvovirus (CPV-2), distemper virus (CDV), and Ehrlichia canis. Samples collected between April 1987 January 1988. Among black-backed (Canis mesomelas), the most sampled species, mean prevalence to CPV-2, CDV, E. canis was 34% (14 positive/55 sampled), 9% (4/55), 3% (1/28), 2% (1/36), respectively. There no significantly...
Abstract: The secretive nature of snow leopards ( Uncia uncia ) makes them difficult to monitor, yet conservation efforts require accurate and precise methods estimate abundance. We assessed accuracy Snow Leopard Information Management System (SLIMS) sign surveys by comparing with 4 for estimating leopard abundance: predator:prey biomass ratios, capture‐recapture density estimation, photo‐capture rate, individual identification through genetic analysis. recorded during standardized in the...
