In an attempt to get scholarship for doctoral studies, generally I (we) have two options: participation in structured doctoral studies or proposal of individual PhD thesis wich allows greater flexibility and requiring greater individual initiation. I will apply for both types, and would like to ask zoochatters what are the possibilities that zoos (eg. in Germany or in Netherlands, or other country) would share their info and matherials (samples of diets, samples of tissues of died zoo animals, space for observation, etc.) and to ask (experienced) zoochatters for their opinion about shaping/eligibility of theses titles involving next goals (two different theses): 1. ''Taurine levels and bioavailability from diets of captive small felids in zoos and their relationship with success of breeding of small cats in captivity'' 2. ''Trying different procedures for behavioral enrichment of zoo snakes, and outcome of such procedures measured by observation, analysing data (eg. breeding success, longevity, reaction to different stimuli, health records, etc.) and laboratory work (eg. measuring stress hormones in snakes?)'' Thank you, Mistakes in writing corrected.
