THE GOOD SPRUCE MOUNT
Having been commissioned to set up two herbariums for the City of St. Cloud, Minnesota, I found myself returning to my plant taxonomy professor to learn if he might have any insight into solving my dilemma--the needles always fell off my mounted spruce specimens. "I have never seen a good spruce mount," was his reply. I returned several months later catching his attention by flipping a mount toward him saying, "Dr. Lindstrom, here's a good spruce mount." His face expressed shock as it flew in his direction, hit the desk, then fell on the floor specimen down. He picked it up and every needle was intact. Here is how it is done.
The materials required are: newspaper (lots of it); 1" x 12" x 16" foam rubber (available at many fabric stores); a 12" x 16" board; a heavy weight (I used a Webster's Unabridged Dictionary); a large cake pan (large enough to hold specimens); a wire rack to cover cake pan; mounting cement (I use polyvinyl acetate); and weights to hold specimen flat while drying.
Instructions. Do not dry/press specimen with heat; instead do the following. 1. Place specimen between several thicknesses of folded newspaper, then set on a hard, flat surface. 2. Place the foam rubber on top of the newspaper, covering it with the board, and setting the weight upon the board. If more than one specimen is to be processed at the same time, a separate board should be used for each specimen. If the weight is not heavy enough to smash the foam rubber, then push down on the weight until it does so smash; this often tears the newspaper but forces the needles to lie flat. 3. Depending upon conditions, one to ten days may elapse before the specimen will lie flat and hold a prostrate shape. If mounting Tsuga (hemlock), about two days is a maximum drying time. If a specimen dries too long, needles fall off during later steps. 4. Place the flattened specimen into the cake pan and pour mounting cement to completely cover the specimen. 5. Remove specimen immediately and place on wire rack allowing excess cement to drip back into pan. Dripping time is less than crucial in high humidity conditions but should be held to a minimum during low humidity. 6. Remove specimen from rack, place it within several thicknesses of folded newspaper, and squeegee off excess glue by pressing with the fingers and palms of the hands through the newspaper. Work fast! Repeat this as often as necessary. Do not invert the specimen; the down-side during drying should remain the down-side during this step and should be the downside for mounting. Inverting the specimen breaks the needles. 7. Cease squeegeeing when the glue becomes tacky enough so that specimen starts to adhere to the newspaper. Then place the specimen on mounting paper and continue squeegeeing, working faster than before, with newspaper from the top-side, pressing the needles onto the mounting paper while removing excess glue. If work proceeds too slowly, the finished specimen will exhibit unsightly crusts of dried cement. 8. Place weights on all parts of the specimen.
This step is crucial because the needles tend to lose their prostrate rigidity while the cement dries. 9. Watch carefully. Usually within minutes, the cement becomes very tacky and, with the needles firmly fixed, it is time to remove the weights. Roll the weights off in the direction of the tips of the needles. If the weights are left in place too long, the beads of cement that tend to accumulate under them will not disperse, detracting from the overall dried appearance. 10. Remove very noticeable beads of cement with a pen knife and allow the specimen to dry completely.
No serious botanist would abuse any specimens, but these can be walked upon without fear of major damage. Because the cement coats the entire specimen with a film, the luster of the fresh specimen remains. This process is being used for all members of the Pinaceae with equal success. One exception is Pinus strobus because the cement fuses the needles together so that it resembles Pinus resinosa and heavy drenchings of spray lacquer were used with this species instead to achieve a similar effect.
This process takes a bit more time, and special handling, but the finished product makes the extra effort very worthwhile.
Tropical South American Plant Project
As tropical forests are destroyed, count-less plant species face certain extinction. Many of these species are unknown to science; their potential benefits therefore remain unknown and unrealized. One particularly cost-effective method of identifying potentially useful tropical plant species is the science of ethnobotany, the study of the use of plants by aboriginal peoples who have an intimate knowledge of these forests and the useful products that they contain. By studying the ethnobotanical lore of these people, we can find new and useful plant species, while generating important economic data for emphasizing the importance of tropical forest conservation.
In recognition of the importance of ethnobotany as a means of demonstrating the inherent value of tropical plant diversity, WWF - U.S. initiated a project entitled "Conservation and Ethnobotany in Tropical South America" in September of 1981. One of the major components of this study has been the development of a standardized format for organizing the wealth of available data on useful plants of lowland South America. To date, a catalogue of over 1000 useful species has been compiled, including data on Latin and vernacular names, distribution, aboriginal use, culture and cultivation, and chemical composition. It is increasingly clear that the magnitude of the information available requires the collaboration of the scientific community to organize the data in a meaningful way.
At a meeting of the Ethnobotany Project Advisory Group (Dr. T. Lovejoy, World Wild-life Fund -- U.S., Chairman; Dr. H. Eshbaugh, Miami University of Ohio; Dr. R. A. Mittermeier, World Wildlife Fund -- U.S.: Dr. T. Plowman, Field Museum of Natural History; and Dr. G. T. Prance, New York Botanical Garden) in February of 1984, it was decided to publish a standardized format which has been developed and invite other researchers to adapt their data to this format which would then be computerized at the Species Conservation Monitoring Unit in Cambridge, England. To request copies of this form, please write: Mark J. Plotkin, Harvard Botanical Museum, Oxford St., Cambridge, MA 02138.
A complete up-to-date treatise on Dino-flagellates will be available from Academic Press late 1984. Edited by David L. Spector the book addresses the following topics: Cell Biology (cell cortex, nuclear structure, cell cycle and mitosis, sexual reproduction, cysts, and unusual inclusion), Biochemistry (physiology and biochemistry, blooms and toxins, and biorhythms), Genetics, Taxonomy, Culturing and Evolution.
AIBS Supports National Biological Survey
The Public Responsibilities Committee of the American Institute of Biological Sciences supports the proposal for a Biological Survey of the United States (BISUS). AIBS suggests that a national survey be a long-term effort spread over several years. It should support the recruiting of new scientists, as well as updating the knowledge and skills of more experienced scientists in the field of systematic biology, as long as such activities fall within the scope of the survey. Initiation of a survey would require the collaboration of scientific organizations and federal and state government agencies to develop a plan or model for the conduct of the survey that would include identification of the kind and extent of effort required, the roles of various participants and where an archive or number of archives should be located and how they would be maintained. In order to pre-vent duplication of effort, collaboration is also needed to identify activities currently conducted throughout the government and elsewhere that are of value to the survey.
A Biological Survey of the United States that would identify and collect information on the characteristics of the plants and animals of the U.S., conduct taxonomic research on the information collected, retain germ plasms and other substances in systematic collections and produce catalogs, maps, and
other printed materials from the information collected is urgently needed. The final products of such a survey would be of significant value to the research and educational activities of all biological scientists and provide a repository of information and specimens that could be used to enhance the quality of all life.
BIOSIS to Increase Coverage
After careful deliberation, the board has approved the largest percentage increase in BIOSIS coverage in the last decade and the largest net increase in the history of the organization. In 1985, BIOSIS will include 440,000 items, a 22% increase in coverage. This advance is in recognition of the in-creasing volume of publications in the life sciences and our perceived responsibility to make BIOSIS the world's most comprehensive source of research information in this field.
