Marriage and association between He Shi from Lujiang and Wang Shi from Lang Ye in the Eastern Jin and the Southern Dynasties;

Determination of the Physiological Reference Values and Comparation Between Equus przewalskii and Domestic Horse;

Study on Mitochondrial DNA D-loop Sequence Variation in Przewalski s Horse(Equus przewalskii);

The Agonistic Behavior and Hierarchical Formation of the Equus przewalskii Herd in the Individual Coalition and Initial Releasing Period

the experiment of parasite esexpelling was made on captive and released Przewalskii horses.

The behavior of Przewalskii horse which lives in different conditions of stalled, semi-released and reintroduced in the Xinjiang Prezwalski Horse Breeding and Studying Center, and the Kalamaili Ungulate Reserve in North Xinjiang, were studied in comparative way, including individual, sub-group and group behavior pattern, time budgets and daily activity pattern from July to September in 2003.

Investigation on genetic diversity between Przewalski horses and Mongolian horses using cytochrome b sequences;

This work aims to study the physiological stress of the captive and released adult male Przewalski horse Equus przewalskii, using the non-invasive method to determine the fecal glucocorticoid metabolites(FGM), in Xinjiang Przewalski Horse Breeding and Studying Centre (89°14′–89°36′N,45°49′–46°04′E) and Kalamaili Natural Reserve of north Xinjiang(44°36′–46°00′E,88°30′–90°03′N) from 2006 to 2007.

The recent study on the new suid materials from the Tuozi Cave shows that they represent a new subspecies:Sus lydekkeri tangshanensis subsp,nov.
