Sentences with phrase «estimating snow leopard population»

Estimating snow leopard population abundance using photography and capture — recapture techniques.

Not exact matches

While estimates of the amount of small mammals snow leopards consume may have been overstated, the importance of large ungulate populations to the snow leopard's diets may have been understated, as this study suggests stable snow leopard populations are possibly more reliant upon large ungulate prey than previously understood.

In order to create effective conservation programs to help protect and conserve populations of endangered snow leopards, whose estimated population is between 4,500 - 7,500 in the wild, University of Delaware researchers are studying their scat to try and understand what the large cats are eating.

Weiskopf explained that a big problem with collecting and identifying scat in the field is that researchers mostly rely on morphological characteristics such as shape, size or associated signs of snow leopards, and since scat from different species can look similar, this can lead to misrepresented population estimates and errors in reporting what the snow leopards are actually eating.

The current estimate for the number of snow leopards is at 20 - 50 individual cats, which is less than 1 % of the global population.

The adult population was estimated separately for each year using photographic data of 8, 11, 13 and 13 adult snow leopards identified respectively for each year.

Comparison of model results with the «known population» of radio - collared snow leopards suggested high accuracy in our estimates.

However, assuming individuals that migrated permanently were lost from the study population (died), we estimated the life expectancy of adult snow leopards to be 5 years (95 % CI: 2.05 — 13.78 years).

The snow leopard population size was estimated independently for each year.

Our work, apart from providing the first estimates of vital rates and other population characteristics of the endangered snow leopard, reiterates the value of long - term monitoring of both abundance and population dynamics for conservation planning and action.

We examine the trends in population abundance and sex ratio, and estimate the detectability, survival probability and probabilities of temporary emigration and immigration for adult and young snow leopards.

Yet, while the abundance estimates indicate a stable snow leopard population in Tost, a closer examination reveals vigorous underlying dynamics.

In this first ever multi-year monitoring of snow leopards, we found the population in Tost Mountains of South Gobi to have remained almost constant, and the estimated mean adult population remained between 12 and 14, and the total population (including young) between 19 and 21.

For felid species with individually distinct fur patterns, such as tigers Panthera tigris [8], jaguars Panthera onca [10]--[12], snow leopards Panthera uncia [13], leopards Panthera pardus [14], cheetahs Acinonyx jubatus [15] and ocelots Leopardus pardalis [16], [17], data from camera - trapping can be analysed using capture - recapture models to estimate abundances and population dynamics [2].

With this, we created the first estimates for snow leopard prey populations.
