Detailed accounts are given for each collected species containing morphometric and scalation data, information on natural history, comments regarding their distribution, the conservation status and key literature. Eleven new species were discovered and described during the survey period. At least five additional taxa might also represent new species but more field work and data collection are necessary to determine their status. For two snake species we provide the first country record and for 23 further species new departamental records are provided. Ongoing phylogenetic studies on the collected material aim to identify and describe further new and cryptic species.
Analyses of the stomach contents of the preserved specimens are used to study aspects of the biological diversity, ecology and behavior of animals. In fact, the diet is one of the major aspects of the ecology of a species. Diet composition can give information on trophic relationships between a species and its environment; it gives insights in feeding behavior and foraging strategies and uncovers sexual or ontogenetic differences within a species.
