Please contact her with any FFSG related issues in the next six months. Miss Suzanne Turnock Suzanne studied for a B.Sc. in Wildlife Conservation at Liverpool John Moores University, and went on to obtain an M.Sc. in Primate Conservation from Oxford Brookes University. Follow- ing university, Suzanne built up her experience by working with various conservation organisations on a voluntary basis, includ- ing the Sumatran Orangutan Society, the Great Apes Film Ini- tiative and Wirral Environmental Network. During her volun- teer work, Suzanne gained valuable experience, particularly in fundraising, publicity and event management. After working as a Primatologist for Operation Wallacea in Honduras for the 2010 field season, Suzanne joined Chester Zoo as Research Assistant. Working as Research Assistant for the past two and a half years, she has worked on a range of projects with a variety of species, from giant otters to jaguars to Humboldt penguins to Chilean pudus! Her work has not only focused on carrying out scientific research but she has also played a key part in revamping the zoo’s research review processes, writing the science webpages and designing the annual review reporting on the scientific activities at Chester Zoo. Suzanne is now looking forward to bringing the skills and knowledge she has developed in her previous positions to the role of Programme Officer and is very excited to be covering Kati’s maternity leave over the next six months. 4 5 Introducing FFSG Regions Southwest Asia and Oriental Realms.

An ex situ conservation project for two critically endangered, endemic species (the thermal rudd Scardinius racovitzai and Melanopsis parreyssii) was developed. A detailed study on the morphometry and ex situ reproduction biology of the thermal rudd provided detailed information for the morphological characterization of this endemic population and for the requirements for its reproduction in captivity and conservation. Introduction This study is a part of a larger research regarding the ex situ conserva- tion of two critically endangered animal species, endemic for the thermal lake in “Peţea Spring” Natural Reserve, near Oradea, northern-western Romania: the thermal rudd Scardinius racovitzai Müller 1958 and the snail Melanopsis parreys- 104 Grigoraș et al. sii (Philippi 1847).

Its population has declined by more than 30% in the past 10 years due to river regulation and drainage of wetlands for agriculture which resulted in a reduced number of backwaters. This species is therefore classed as Vulnerable. Photograph © Andreas Hartl.
