The Institute of Arctic and Alpine Research, University of Colorado, has
recently published two more titles in its Occasional Paper series.
ECOLOGICAL PROCESSES IN A COLD DESERT ECOSYSTEM: THE ABUNDANCE AND SPECIES
DISTRIBUTION OF ALGAL MATS IN GLACIAL MELTWATER STREAMS IN TAYLOR VALLEY,
ANTARCTICA. By A. S. Alger, D. M. McKnight, S. A. Spaulding, C. M. Tate, G.
H. Shupe, K. A. Welch, R. Edwards, E. D. Andrews, and H. R. Rouse.
Occasional Paper No. 51, 1997. 108 pp. $15 plus $2 shipping and handling.
Abstract: The McMurdo Dry Valleys, and Long-Term Ecological Research site
located in South Victoria Land, are the largest of the polar desert oases
found along the coast of Antarctica. Glacial meltwater streams are an
important aquatic habitat in the McMurdo Dry Valleys. This report presents
results on the abundance and species distribution of algal mats of 16
streams in Taylor Valley. Results indicate that species of filamentous
cynbacteria are the most abundant algae in the dry valleys streams.
PROCEEDINGS OF THE SECOND CIRCUMPOLAR ARCTIC VEGETATION MAPPING WORKSHOP,
ARENDAL, NORWAY, 19-24 MAY 1996; THE CAVM-NORTH AMERICA WORKSHOP, ANCHORAGE,
ALASKA, US, 14-16 JANUARY 1997. Edited by Donald A. Walker and Andrew C.
Occasional Paper No. 52, 1997. 62 pp. $10 plus $2 shipping and handling.
Abstract: This publication contains the proceedings from two workshops that
describe progress toward a Circumpolar Arctic Vegetation Map (CAVM). The
bulk of the volume is devoted to the Second International CAVM Workshop,
which was attended by representatives from all the circumpolar nations.
Extended abstracts of 27 papers describe the progress that has been made
since the first workshop in St. Petersburg, Russia, 1994. The abstracts are
preceded by introductory address and a keynote address. The second part
contains results from the CAVM- North American workshop, which was attended
by participants from Greenland, Canada, and the U.S. A summary of the
proceedings and a paper describing a prototype map for northern Alaska are
