Collecting and Preparing Specimens of Araceae

Preparing Amphibians as Scientific Specimens

Documentation of the species recorded in biodiversity and inventory projects frequently involves preparation of voucher specimens, which are extremely important for the credibility of such studies (see Chapter 5). In addition, these specimens and their accompanying field notes are valuable sources of scientific information used in systematic, biogeographic, evolutionary, and ecological studies....

Demonstration of Ramsay Smith's Method of Rapidly Preparing Histological Specimens

as ethyl chloride, and much cheaper.) 2. The method of cutting, which consists of a continuous raising of the screw with the left hand simultaneously with a rapid to and fro movement of the knife, without any attempt to adapt the screw at each cut. This is not only rapid, but gives exceedingly good sections, although the exact measurement of them is not attempted. 3. The method of mounting perm...

P96 Technique for Tissue Plastination in Preparing Long-Lasting Anatomical Specimens

Background: Plastination is a technique of long-term preservation of the natural tissues without the typical problems related to wet specimens. Plastinated specimens are durable, dry, and flexible. In this process, the water and fat in biological tissues are substituted by a curable polymeric resin, i.e., subsequently cured. In this study, a new unsaturated polyester resin (P96) was synthesized...
