The Persian leopard Panthera pardus tulliana is an endangered large felid living in mountainous landscapes of the Caucasus, Southwest Asia and parts of Central Asia. In this paper, we review available literature to update our information on the status, population, ecology, threats, and management recommendations in regard to this big cat in the region. Most of the Alborz and Kopetdag Ecoregions harbour the largest population of Persian leopard with some protected areas having the highest densities of these carnivores. A total of 348 to 440 leopards are guessed to exist in the region, making it one of the largest continuous leopard hotspots across Asia. Almost 80% of the population exists in Iran, followed by Turkmenistan which holds the second largest Persian leopard population, while the leopard population in Kazakhstan mainly depends on transboundary transient individuals from Turkmenistan.

Монография представляет собой эколого-фаунистическую сводку научно-популярного характера о животном мире Туркменистана и вопросам его охраны. Книга содержит обобщающие и детальные сведения по истории изучения позвоночных животных, особенностям среды их обитания, составу, эколого-фаунистическим и зоогеографическим характеристикам, о роли позвоночных животных в экосистемах и жизни человека, биологическом разнообразии, его охране в целом и в частностях, включая систему особо охраняемых природных территорий Туркменистана.

Toxicity tests are commonly used as a tool to determine the standards of water quality for chemicals and to discover appropriate organisms as bioindicators in toxicological studies, and also could be used as an essential tool for evaluation of the pollutant effects in aquatic ecosystems. The aim of the present study was to evaluate the sensitivity of two Caspian fish species, Caspian trout as an endangered species and Caspian Kutum using the static acute toxicity in response to nonylphenol, which is widely discharged into the Caspian Sea environment.

In addition, Caspian trout was approximately 6 times more sensitive than Caspian Kutum. Nonylphenol was reflected to be "highly toxic" to Caspian trout and "moderately toxic" to Caspian Kutum. The results could be considered in preparing plans for conservation and restocking management of Caspian Kutum and the endangered Caspian trout.
