| Abstract |
In late summer, in a semi-arid mountain range in Nepal, we compared 3 field methods for determining the botanical composition of herbivore diets. Data were collected from the same animals belonging to 1 herd of domestic yak (Bos grunniens) and 2 herds of mixed smallstock, consisting of domestic goats (Capra hircus) and sheep (Ovis aries). Bite count, feeding site examination, and microhistological analysis of feces gave different estimates of forage categories and plant species in both animal groups. Because yaks grazed in other vegetation communities when not observed for bite-counts and feeding signs, the results from the latter methods could not be compared directly with that from fecal analysis. In smallstock, feeding site examination gave higher estimates of graminoids and lower estimates of shrubs than the other 2 methods, probably because all feeding signs on shrubs were not detected. Bite-counts and fecal analysis gave comparable results, except that forbs were underestimated by fecal analysis, presumably due to their more complete digestion. Owing to the difficulty in collecting samples that are representative of the entire grazing period and the problem of recording feeding signs correctly, both feeding site examination and bite-counts are unsuitable methods for studying the food habits of free ranging domestic and wild herbivores. Microhistological analysis of feces appears to be the most appropriate method, but correction factors are needed to adjust for differential digestion. The systematic use of photomicrographs improves the speed and accuracy of the fecal analysis. |

| Abstract |
The purpose of this study was to determine the molecular basis for a relative deficiency in the cat of cytosolic arylamine N- acetyltransferase (NAT), an enzyme family that is important in the metabolism of xenobiotics and that normally consists of at least two related enzymes, NAT1 and NAT2. N-acetyltransferase in feline liver showed high affinity (mean Km = 2.1 microM) for p-aminobenzoic acid, an NAT1 selective substrate in humans and rabbits, but showed a very poor affinity (mean Km > 10 mM) for sulfamethazine, an NAT2 selective substrate in humans and rabbits. Immunoreactive N-acetyltransferase was detected in feline liver, bladder and colon using an NAT1-specific antipeptide antibody, but was not detected in any tissues using an NAT2- specific antibody. Southern blot analysis of genomic DNA demonstrated a single band in domestic cats using each of six restriction digests; single bands were also found on Southern blot analysis of six wild felids. The deduced amino acid sequence of the central portion of feline N-acetyltransferase, obtained by polymerase chain reaction amplification in both domestic cats and seven wild felids (lion, tiger, lynx, snow leopard, bobcat, Asian leopard cat and cheetah), contained three residues, Phe125, Arg127, and Tyr129, which determine NAT1-like substrate specificity in humans. These results support the conclusion that cytosolic arylamine N-acetylation activity is low in the cat because of the presence of a single N-acetyltransferase that has substrate specificity, immunogenicity and sequence characteristics similar to human NAT1, and that the unusual presence of only a single N- acetyltransferase gene appears to be a family wide trait shared by other felids. |

| Abstract |
An expert evaluation of the numbers of snow leopard and its preys, Siberian ibex and long-tailed marmot, was made on the basis of surveys conducted in Hissar nature reserve in 1999. The total number of the snow leopard is estimated at 12-16 individuals, whereas that of the Siberian ibex at 1000 individuals. An average density of the population of the long tailed marmot ranges at 4,8 individuals per ha. The ratio of the numbers between the snow leopard, Siberian ibex and long tailed marmot is 1:68:450. The major threats for the snow leopard are poaching on the borders of the nature reserve, a decrease in of preys, shrinking of the range in areas adjoining the nature reserve as a result of intensification of industrial activities and disturbing factors. For the Siberian ibex and long tailed marmot the major limiting factors are the shrinking of the areas and deterioration of the forage value of the high-mountain pastures, as well as the direct competition for forage with domestic animals at the sites adjoining the territory of the nature, as well as disturbing factors. |

| Abstract |
A high percentage of rare species in Central Asia experience limited conditions for distribution. Geographic centers with higher species diversity are generally constrained in terms of territory: they are formed when ranges overlap. But in Central Asia and along its borders with Russia, centers of biodiversity overlap at the very marginal edges of ranges. Central Asian species cross into Russian territory, where desert and steppe are replaced by thick forest. Here the northern borders of their ranges are sharply fragmented and isolated. Typical examples for Central Asia are the ranges of the cheetah (Acinonyx jubatus), Asian leopard (Panthera pardus caucasica), striped hyena (Hyaena hyaena), Bukhara deer (Census elaphus bactrianus), markhor (Capra falconeri), blue sheep (Pseudois nayauf) and argali (Ovis ammon). In Russia are the Altai subspecies of argali, the Siberian argali (O.a.ammon), the mountain goat (Capra sibirica), Mongolian gazelle (Procapra gutturosa), snow leopard (Uncia uncia), Pallas' cat (Felis manul), dhole (Cuon alpinus), grey marmot (Marmota baibacina), Mongolian marmot (M. sibirica) and tolai hare (Lepus tolai). Where the numbers o f individuals has fallen to extreme lows, the most effective mechanism for species survival may be supporting the integrity of ranges, in order to preserve population exchanges between neighboring groups. The geographic location of reserves and other protected territories is vitally important for the survival of Central Asian species, given the acute fragmentation of their ranges. These reserves should include significant, viable centers of population the key places. Wherever the creation of permanent protected territories is impossible, a new tactic must be found, such as introducing temporary limitations on the use of land for agriculture and hunting. But all protected territories, whether temporary or permanent, should be connected, forming a core and periphery. The marginal range areas must not be forgotten, if total protection of endangered populations is to be accomplished. |
