List of research projects that have been conducted or supported by the Jerusalem Zoo in recent years

Enrichment and captive management: 

1. Affects of food dispersal on zebra behaviour and exhibit-area use
2. Affects of sleeping arrangements on male white-rhino hormone levels and behaviour 
3. Use of various playbacks on Siamang behaviour and exhibit-area use 
4. Comparative study of affects of enrichment on behaviour of various feline species 

Re-introduction:

1. Preliminary ecological survey of the critically endangered Negev tortoise (Testudo werneri) populations in the western Negev sands 
2. Comparative mitochondrial DNA analysis of Testudo werneri specimens from the wild and the Tisch Family Zoological Gardens
3. Short-term dispersal of re-introduced Mesopotamian fallow-deer in the Jerusalem Hills region
4. Temporal changes in stress and sex hormone levels of Mesopotamian fallow-deer during re-introduction
5. Behavioural differences in Mesopotamian fallow-deer between the Zoo and the acclimatization enclosure (prior to re-introduction)
6. Behavioural changes of Mesopotamian fallow-deer individuals after re-introduction
7. Endozoochory (seed-dispersal) by re-introduced Mesopotamian fallow-deer
8. Evaluating a method for long-term study of dispersal, behavioural patterns and habitat preference of re-introduced Mesopotamian fallow-deer
9. GIS analysis of proposed area for sand-cat re-introduction 

Reproduction:

1. Temporal changes in female and male cheetah sex hormone levels
2. Sex hormone levels in Asian elephant cows before, during and after pregnancy 

Veterinary:

1. Profiling temporal changes of, and treatment effects on re-current keratitis among Asian elephants
2. Efficiency of long-acting anti-fungal treatment in Siamang gibbons
3. Efficiency of a slow-release implant as a long-acting antibiotic treatment in large herbivores
4. Characterization of rabies blood neutralizing antibody levels in vaccinated Asian elephants
5. The efficiency of darted GnRH agonist (deslorin) implant as a contraceptive in Giraffe

Others:

1. Antler asymmetry in Mesopotamian fallow-deer, a highly inbred species
2. Insectivore bat diversity at the Tisch Family Zoological Gardens
