Is there such a vocabulary available?

There are several "common" ontologies published for Open Data. Here are some:
Linked Open Vocabulary (LOV): http://lov.okfn.org/dataset/lov/
Linked Open Data (LOD) : http://linkeddata.org/
We (OpenGeoCode) have our own published ontology:
Vocabulary: http://www.opengeocode.org/cude1.2/LinkedCSV-Vocab.php
Specification: http://www.opengeocode.org/cude1.2/csv1.2.php
The open directory project DMOZ is probably too shallow for scientific use, but maybe appropriate to get a "average Joe" perspective on concepts visible in such topics as
Another more extensive, but messier and more involved procedure to look into the structure of Wikipedia categories. Here is an example tree for Environment. Problem: they are chaos.
You could also take a look at Adam Pease's SUMO (Suggested Upper Merged Ontology) which is quite broad and covers those knowledge domains.
