Carcasses of animals, faeces and other biological material found in the wild may be very useful for obtaining data about wild populations. The importance of information about diseases is self-understood. Carcasses of animals healthy when killed, such as road kills or victims of poachers, may provide valuable information about normal, healthy tissues (Wobeser, Spraker 1980). Besides, information and materials not related to diseases, but useful for other research may be obtained.
It can no longer be regarded as ethical to kill threatened wild animals
for research or for obtaining specimens for collections. Carcasses found
or confiscated may serve as a better source of material for reference collections.
Therefore, before a necropsy is done, initial careful consideration will
be necessary which parts have to be damaged or destroyed for detection
of disease, and which should rather be preserved for some other purpose.
Such parts may for instance be skins, skeletal material for taxonomic reference
collections or the preserved alimentary tract together with its content
for nutritional analysis, se also sampling recommendations for reference
collections (one of us: A. Nekaris; see also Groves, 2002 in press)
The usefulness of collected data and specimens largely depends on adequate collection methods, recording, labelling and preservation. Different preservation methods are necessary, dependant on the kind of material and data needed. This chapter tries to provide all necessary information to get a maximum amount of information from carcasses and other materials, allowing better protection of populations and maybe their habitats.
In cases of possible epidemics or zoonoses, it will of course be necessary
to consider all necessary measures and legal requirements to assure that
no dangerous infectious agent is spread into other regions by collected
items (one of us: K. Petry).
