Abstract: Much is still unknown about the ecology of snakes, especially in remote geographic regions or spatially-difficult areas to access. In general, snakes are elusive and may be difficult to capture, either because of their habits or because they are venomous. However, it is possible to utilize the “unwanted” portions of snakes, and other animals for that matter, to learn a great deal about various aspects of ecology and biology, including diet, reproduction, seasonal activity, population dynamics and morphology. Recently a study of regurgitations produced data that lead to the recovery of the United States Federally Threatened Lake Erie Watersnake (Nerodia sipedon insularum) and fecal samples allowed for the discovery of a new primary diet item for Mollusk-eating Snakes (Dipsas spp.). Another much understudied resource is dead specimens found runover on roads, commonly called DORs (dead on road). Although not in the best condition, these specimens can provide a tremendous amount of data and ample tissue samples without harm to a live individual. Currently, analyses of DORs are revealing new dietary records for elusive Coralsnakes (Micrurus), information about female reproductive cycles (e.g., Sibon) and leading to new taxonomic relationships for rare snakes (e.g., Masticophis). Here we present information on current research, as well as, the potential data available and the conservation-oriented advantages of using these underappreciated and unwanted parts of organisms. Being able to learn important ecological information from typically discarded portions is one more way to help conserve species and advance science.
