the region’s carnivores. Conservationists working in these<br />

underdeveloped areas that face serious economic impacts<br />

from livestock losses have turned to incentive schemes<br />

to motivate local communities to protect carnivores. We<br />

describe a pilot incentive experiment in India that aims<br />

at enhancing wild prey density by creating livestock-free<br />

areas on common land. We also describe how income<br />

generation from handicrafts and tourism in Mongolia is<br />

helping to curtail poaching and retaliatory killing of snow<br />

leopards. However, initiatives that have tried to offset the<br />

costs of living with carnivores and to make conservation<br />

beneficial to the affected people have thus far been small,<br />

isolated, and heavily subsidized. Making these initiatives<br />

more comprehensive, expanding their coverage, and<br />

internalizing their costs are future challenges for<br />

conserving large carnivores like the snow leopard.<br />

lynx predation for roe deer Capreolus capreolus and<br />

chamois Rupicapra rupicapra mortality in the Swiss<br />

Jura Mountains. Wildlife Biology 8(2):109-115.<br />

Prey class selection and kill rates by lynx Lynx lynx<br />

were studied in the Swiss Jura Mountains from March<br />

1988 until May 1998 to evaluate the significance of lynx<br />

predation for roe deer Capreolus capreolus and chamois<br />

Rupicapra rupicapra. We found clear differences in<br />

the kill rates and prey class selection between lynx<br />

of different age, sex and breeding status. Male lynx<br />

killed more chamois than female lynx, and chamois<br />

was never found in kill series of subadult lynx. Family<br />

groups had the highest kill rate. They killed an ungulate<br />

every 5.0 days, compared to an average of 6.2-6.6 days<br />

for single lynx. During our 10-year study, the density<br />

of independent lynx was rather stable, ranging within<br />

0.94-1.01 individuals/100 km 2 . Based on the observed<br />

kill rates and the estimated lynx population structure<br />

we calculated that lynx killed 354 +/-13 roe deer and<br />

8713 chamois annually in the 710 km 2 study area. The<br />

magnitude of lynx predation on roe deer and chamois<br />

was primarily shaped by the lynx population structure. A<br />

decline in the number of resident male lynx reduced the<br />

number of chamois killed in the study area by 1/4 of the<br />

previous number due to the difference in prey selection<br />

of male and female lynx. There was a difference in the<br />

most frequently killed age and sex classes between roe<br />

deer and chamois: lynx killed more male chamois (39%)<br />

than females or fawns, whereas in roe deer, does (38%)<br />

were most often killed. By altering adult survival, lynx<br />

predation has a significant impact on prey population<br />

dynamics. Lynx killed a maximum of 9% of the roe deer<br />

and 11% of the chamois spring population. Considering<br />

the differences in the recruitment potential of the two<br />

prey species, lynx has a greater impact on chamois than<br />

on roe deer.<br />

population size of grizzly bears using hair capture,<br />

DNA profiling, and mark-recapture analysis. Journal<br />

of Wildlife Management 64:183-193.<br />

We used. DNA analysis to estimate grizzly bear (Ursus<br />

arctos) population size in a 9,866 km 2 area in southeast<br />

British Columbia and a 5,030 km 2 area in southwest<br />

Alberta. We sampled bears by removing hair at bait<br />

sites surrounded by a single strand of barbed, wire. DNA<br />

profiling with microsatellites of the root portion of the<br />

hair was used to identify individuals. We collected hair<br />

from 109 different bears and had 25 recaptures in 5 10-<br />

day trapping sessions in British Columbia. In Alberta we<br />

collected hair from 37 bears and had 9 recaptures in 4<br />

14-day sessions. A model in program CAPTURE (M-h)<br />

that accommodates heterogeneity in individual capture<br />

probabilities estimated the population size in British<br />

Columbia as 262 (95% CI = 224-313) and in Alberta as<br />

74 (60- 100). We believe that hair capture combined, with<br />

DNA profiling is a promising technique for estimating<br />

distribution and abundance of bears and potentially<br />

many other species. This approach is of special interest<br />

to management biologists because it can be applied at the<br />

scale conservation and management decisions are made.<br />

Fuller. 1999. Infectious disease and the conservation<br />

of free-ranging large carnivores. Animal Conservation<br />

2:241-254.<br />

Large carnivores are of vital importance to the stability<br />

and integrity of most ecosystems, but recent declines in<br />

free-ranging populations have highlighted the potentially<br />

devastating effect of infectious diseases on their<br />

conservation. We reviewed the literature on infectious<br />

diseases of 34 large (maximum body mass of adults<br />

>20 kg) terrestrial carnivore species, 18 of which are<br />

considered to be threatened in the wild, and examined<br />

reports of antibody prevalence (seroprevalence) and<br />

cases of infection, mortality and population decline. Of<br />

52 diseases examined, 44% were viral, 31% bacterial and<br />

the remainder were protozoal or fungal. Many infections<br />

were endemic in carnivores and/or infected multiple<br />

taxonomic families, with the majority probably occurring<br />

via inhalation or ingestion. Most disease studies<br />

consisted of serological surveys for disease antibodies,<br />

and antibody detection tended to be widespread implying<br />

that exposure to micro-organisms was common.<br />

Seroprevalence was higher in tropical than temperate<br />

areas, and marginally higher for infections known<br />

to occur in multiple carnivore groups. Confirmation<br />

of active infection via micro-organism recovery was<br />

less common for ursids than other taxonomic groups.<br />

Published descriptions of disease-induced population<br />

decline or extinction were rare, and most outbreaks were<br />

allegedly the result of direct transmission of rabies or<br />

canine distemper virus (CDV) from abundant carnivore<br />

species to less-common large carnivores. We conclude<br />

that the threat of disease epidemics in large carnivores<br />

may be serious if otherwise lethal infections are endemic<br />

in reservoir hosts and transmitted horizontally among<br />
