Although these literature searches were originally conceived as providing working documents for our own researches, it soon became apparent that this comprehensive catalogue of literature and illustrations should be made generally available rapidly and freely as a working tool for all those interested in working on Trichoptera material from Africa, especially for colleagues in far-distant institutes and without access to large libraries. Each page will record the name of the species, its distribution, the best illustrations of its diagnostic characters available in the literature, usually of genital structures, and the appropriate original literature. This bibliographic reference work containing over 1200 species and subspecies in 26 families and 109 genera makes no claim to be complete. The clarification of problematic systematic questions or synonyms was also not one of its aims. ... [Information of the supplier]
This site is being made to speed up the general identification of dried specimens of Neotropical plants. It will be most useful to professional biologists and others doing species inventories of natural areas, ecology, and ethnobotany. It will be useful for identifying families, genera or plant species in regions for which comprehensive field guides are not available, or where manuals depend on the use of technical floral or fruit characters absent in the voucher specimens. It will even be useful to paleobotanists and others with interest in comparative morphology of tropical plants. To this end we are providing a desktop reference set of high-quality images of dried herbarium specimens for comparison. These will represent a broad range of Neotropical genera and common species. The underlying strategy is to have just a few examples of each species, specimens that are typical or illustrative of that species. Preference is given to specimens that have a good set of leaves as well as flowers or fruit, and to specimens with an authoritative identification. Specimens of juveniles will be included when available and when significantly different in appearance from adults. ... [Information of the supplier]
