Abstract: Empirical data on behavior, such as space‐use patterns, are important to the success of animal reintroductions. We studied space‐use patterns in a growing population of Asiatic wild ass (   Equus hemionus) reintroduced into the Ramon erosion cirque in the Negev desert, Israel. Between 1988 and 1995 we used direct observation to determine the location and association of males and females. All adult females and dominant males were individually recognized. Home ranges of dominant males… 
Space Use, Survival, Movements, and Reproduction of Reintroduced Louisiana Black Bears
TLDR
The results suggest that the Louisiana reintroduction program is proceeding favorably; however, future studies should continue to monitor survival and reproduction of reintroduced females in Louisiana, and additional demographic parameters should be estimated to determine if the new population is self-sustaining.
Exploratory and territorial behavior in a reintroduced population of Iberian lynx
TLDR
Findings indicate that the Iberian lynx population has successfully been established but it takes more than 5 years to stabilize the territories in the area, and an effect of sex on the sizes of the territories established.
Impact of repeated releases on space-use patterns of Persian fallow deer
TLDR
Movement patterns of released Persian fallow deer in this reintroduction indicate a slow, gradual movement away from the release site and establishment of a home range within a year.
Space-Use Patterns of the Asiatic Wild Ass (Equus hemionus): Complementary Insights from Displacement, Recursion Movement and Habitat Selection Analyses
TLDR
This study studied the endangered Asiatic wild ass in the Negev Desert, Israel, using GPS monitoring and direct observation and found that the main landscape-related factors affecting the species’ space-use patterns, on a daily and seasonal basis, were vegetation cover, water sources and topography.
Effectiveness of Multiple Release Sites in Reintroduction of Persian Fallow Deer
TLDR
In this model, releasing animals into the wild at multiple sites produced higher population growth and greater spatial expansion than releasing animals at only one site and a consecutive-release approach was superior to an alternate- release approach.
Development of genetic structure in a heterogeneous landscape over a short time frame: the reintroduced Asiatic wild ass
TLDR
This work explored the development of population genetic structure in the reintroduced Asiatic wild ass in Israel, four generations after the onset of reintroduction, during which the population experienced demographic growth and range expansion over a complex landscape.
Post-release Movement Behaviour and Survival of Kulan Reintroduced to the Steppes and Deserts of Central Kazakhstan
Asiatic wild ass, or kulan (Equus hemionus kulan) were once a key species of the Eurasian steppes and deserts. In Kazakhstan they went extinct by the 1930s. Early reintroductions have reestablished
Seasonal and circadian changes in the home ranges of reintroduced Persian fallow deer
TLDR
It is suggested that so far, the reintroduced Persian fallow deer have adjusted well to living in the wild and that the chances of achieving A self-wild population are good, however, further research for extended period should verify these conclusions.
Subspecies hybridization as a potential conservation tool in species reintroductions
TLDR
The study provides rare empirical evidence of the successful application of subspecies hybridization in a reintroduction and supports use of intraspecific hybridization as a tool to increase genetic diversity in conservation translocations.

Population Dynamics of a Reintroduced Asiatic Wild Ass (Equus Hemionus) Herd
TLDR
The dynamics of a reintroduced Asiatic wild ass (Equus hemionus) population for 10 yr following the first successful release into the wild is studied, concluding that the slow growth of the female population was due to a low reproductive success of females in the early years following reintro- duction, and a male-skewed progeny sex ratio among prime-aged reintroduced females.
Observations on social organization and behaviour of African and Asiatic wild asses (Equus africanus and E. hemionus).

TLDR
Territoriality in E. africanus and E. hemionus was found to be basically identical to that of Grevy's zebra, and members of both species live in unstable groups of variable composition.

The problems posed by threatened populations are stimulating innovative research in a variety of fields. We introduce four areas that have emerged over the past decade: descriptive genetics, captive

As the number of threatened species increases, and as we understand more about the extent of the problem, the need for effective and efficient means of identifying endangered species and populations
Minimum Population Sizes for Species Conservation
Many species cannot survive in mandominated habitats. Reserves of essentially undisturbed habitat are necessary if such species are to survive in the wild. Aside from increased efforts to accelerate

TLDR
Evidence is presented that, rather than killing infants directly, invading males induce abortions in females unprotected by their resident stallions and these females are then inseminated by the new males.
