A protocol for the use of roadkill or stranded animals as material for research and teaching

Abstract

Many aspects of the Brazilian fauna dynamics remain unknown. Often, researches on zoology depend on invasive protocols that require the death of specimens of rare or endangered species. This is the first time a combined protocol is proposed for the use of roadkill or stranded animals in research and teaching by different professionals. It turns such undesired deaths into a source of taxonomic material, tissue for histology, DNA analysis and parasitological tests and as ecological evidence. This is a non-invasive protocol that requires no sacrifice of any specimens. Skins and skeletons can be processed as taxonomic material and stomach contents provide information about feeding habits and ecology. In addition, regional zoological collections can be improved and these specimens can be used for practical classes in different areas, including environmental conservation. This article thus describes thirteen steps which can be taken to take the best advantage of these victims of human progress.
