  Title Unsupervised recognition of individual tigers and snow leopards from their footprints Type Miscellaneous
  Year 1998 Publication Animal Conservation Abbreviated Journal (up)  
  Volume 1 Issue Pages 253-262  
  Keywords captive; panthera tigris; panthera uncia; snow leopard; techniques; tiger  
  Abstract This study presents the testing of two unsupervised classification methods for their ability to accurately identify unknown individual tigers, Panthera tigris, and snow leopards, Panthera uncia, from their footprints. A neural-network based method, the Kohonen self-organizing map (SOM), and a Bayesian method, AutoClass, were assessed using hind footprints taken from captive animals under standardized conditions. AutoClass successfully discriminated individuals of both species from their footprints. Classification accuracy was greatest for tigers, with more misclassification of individuals occurring for snow leopards. Examination of variable influence on class formations failed to identify consistently influential measurements for either species. The self-organizing map did not provide accurate classification of individuals for either species. Results were not substantially improved by altering map dimensions nor by using principal components derived from the original data. The interpretation of resulting classifications and the importance of using such techniques in the study of wild animal populations are discussed. The need for further testing in the field is highlighted.

  Title Multiple ocular colobomas in the snow leopard (Uncia uncia) Type Miscellaneous
  Year 2002 Publication Veterinary Ophthalmology Abbreviated Journal (up)  
  Volume 5 Issue Pages 197-199  
  Keywords captive; Coloboma; cub; eyelid; ocular fundus; snow leopard; Uncia uncia  
  Abstract Two singleton female snow leopard cubs are reported with bilateral central upper lid colobomas. In addition, one cub had a coloboma of the fundus in one eye extending from the lower optic disc region. Surgical treatment by wedge resection was successful in both cases. Details of ocular colobomas in the other snow leopards reported in the literature are described and it is suggested that the exact etiology of the condition in this species may be discovered by further study of similar colobomas in the domestic cat.

  Title Serum concentrations of oestradiol and progesterone, and sexual behaviour during the normal oestrous cycle in the leopard (Panthera pardus) Type Miscellaneous
  Year 1988 Publication Journal of Reproductive Fertility Abbreviated Journal (up)  
  Volume 82 Issue Pages 43-49  
  Keywords captive; Ovulation; Panthera pardus; Progesterone; Serum; sexual behaviour  
  Abstract Three mature nulliparous female leopards were studied for 5 years. During three separate 6-month periods serum oestradiol and progesterone concentrations were measured at weekly intervals. Oestradiol was elevated over 21 pg/ml for 54 weeks during these 3 periods, and 36 oestradiol peaks (65\m=.\8\m=+-\6\m=.\3pg/ml (mean \m=+-\s.e.m.), range 21\p=n-\172pg/ml) were identified. Daily frequency of feline reproductive behaviours averaged over each week increased from 1\m=.\9\m=+-\0\m=.\2(n = 93) during weeks with low serum oestradiol concentrations (<21 pg/ml) to 5\m=.\3\m=+-\0\m=.\6(n = 54) during weeks when serum oestradiol concentrations (>21 pg/ml) were high. Increased serum progesterone concentrations (13\p=n-\98n/gml) were observed on 5 occasions in 2 leopards housed together. These presumptive luteal phases lasted from 1 to 5 weeks. Baseline progesterone values were 1\m=.\6\m=+-\0\m=.\4 ng/m(nl= 131). No progesterone increments were observed in isolated animals, and serum concentrations remained at baseline levels. These limited observations suggest that female leopards do not require intromission to induce ovulation and luteal function. The average interval between oestradiol peaks for cycles with no progesterone increment was 3\m=.\4weeks (range 1\p=n-\6weeks). The interval for the 3 complete cycles associated with elevated progesterone concentrations was 7\m=.\3weeks. Analysis of sexual behaviours over the 5-year study period revealed no evidence of seasonality in these

captive leopards.

  Title A Survey of Serum and Dietary Carotenoids in Captive Wild Animals Type Journal Article
  Year 1999 Publication The Journal of Nutrition Abbreviated Journal (up)  
  Volume 129 Issue Pages 380-390  
  Keywords captive; carotenoids; dietary; Serum; snow leopard; survey; wild; Animals; Animal  
  Abstract Accumulation of carotenoids varies greatly among animal species and is not fully characterized.

Circulating carotenoid concentration data in captive wild animals are limited and may be useful for their management.

Serum carotenoid concentrations and dietary intakes were surveyed and the extent of accumulation

categorized for 76 species of captive wild animals at Brookfield Zoo. Blood samples were obtained opportunistically

from 275 individual animals immobilized for a variety of reasons; serum was analyzed for a- and b-carotene,

lutein 1 zeaxanthin, lycopene, b-cryptoxanthin and canthaxanthin. Total carotenoid content of diets was calculated

from tables and chemical analyses of commonly consumed dietary components. Diets were categorized as

low, moderate or high in carotenoid content as were total serum carotenoid concentrations. Animals were

classified as unknown, high, moderate or low (non-) accumulators of dietary cartenoids. Nonaccumulators had total

serum carotenoid concentrations of 0-101 nmol/L, whereas accumulators had concentrations that ranged widely,

from 225 to 35,351 nmol/L. Primates were uniquely distinguished by the widest range of type and concentration

of carotenoids in their sera. Most were classified as high to moderate accumulators. Felids had high accumulation

of b-carotene regardless of dietary intake, whereas a wide range of exotic birds accumulated only the xanthophylls,

lutein 1 zeaxanthin, canthaxanthin or cryptoxanthin. The exotic ungulates, with the exception of the bovids, had

negligible or nondetectable carotenoid serum concentrations despite moderate intakes. Bovids accumulated only

b-carotene despite moderately high lutein 1 zeaxanthin intakes. Wild captive species demonstrated a wide variety

of carotenoid accumulation patterns, which could be exploited to answer remaining questions concerning carotenoid

metabolism and function.

  Title Big cats in captivity: a quantitative analysis of enrichment Type Journal Article

  Keywords abnormal-behavior; behavior; captive-animal-care; endangered; threatened-species; zoos; enrichment; abnormal; captive; Animal; care; threatened; species; browse; 1280; study; big; big cats; Cats; cat; zoo; effects; Lions; lion; jaguar; snow; snow leopards; snow leopard; snow-leopards; snow-leopard; leopards; leopard; behaviour; using; activity; activities; change; presence; enclosures; range; scent; cage; horse; hides; management  
  Abstract Studies on three species of big cats at Dublin Zoo have led to firm conclusions about the effects of certain forms of enrichment, some of which will be presented here. Lions, jaguars, and snow leopards were studied over two years and their behaviours quantified using focal animal sampling during selected hours during daylight. By comparison of these activity budgets with and without the enrichments being present, it was possible to identify the exact behavioural changes caused by each enrichment method, and to quantify these changes. In this contribution we present results showing that the presence of a platform in both lion and jaguar enclosures dramatically reduced stereotypic pacing behaviour. We will demonstrate that the effects of short term enrichment devices may have a wide range of effects on behaviours which outlast the presence of the stimulus. For instance scents added to the cage, or food/play items such as horse hides, hidden fish or ice-blocks often reduce pacing and increase resting later in the day, even after the cats have ceased using the enrichment items. This reduction in pacing and increase in resting time often meant that the amount of the enclosure used per hour was actually reduced with the presence of new stimuli, as result opposite to what might have been expected. The results of these studies will be discussed in relation to effective animal management.

  Title Effects of construction noise on behaviour of and exhibit use by Snow leopards Uncia uncia at Basel zoo Type Miscellaneous
  Year 2008 Publication International Zoo Yearbook Abbreviated Journal (up)  
  Volume 42 Issue Pages 199-205  
  Keywords behaviour; captive; construction noise; exhibit use; snow leopard; Uncia uncia; zoo  
  Abstract Noise caused by human activities can cause stress in animals. We examined whether noise from construction sites affects the behaviour of and exhibit use by three Snow leopards Uncia uncia at Basel zoo. The behaviour and location of the animals were recorded at 1 minute intervals, using the instantaneous scan sampling method over a period of 216 hours (104 hours on noisy days and 112 hours on quiet days). The animals differed individually in their responses to the construction noise. On noisy days, the Snow leopards generally spent less time in locomotion and more time resting, but even on quiet days, resting was the predominant behaviour performed. Under noisy conditions, they increased social resting and decreased resting alone. Walking and social walking were also reduced on noisy days. Furthermore, the Snow leopards spent considerably more time in the remote offexhibit enclosure under noisy conditions. Independent of background noise, they stayed more than half of the time in the caves and the forecourts of the outdoor enclosure. On quiet days, the Snow leopards used more sectors of their exhibit than on noisy days. The results indicate that the Snow leopards responded to construction noise by increasing the amount of time spent resting and by withdrawing to the remote parts of their exhibit.
