FIRES IN MEXICO AND CENTRAL AMERICA
Wildfires in Mexico and Central America have been burning
for months, devastating millions of acres of forest and grassland
in the region and blanketing parts of the United States with
smoke that has created health emergencies. The fires have been
caused by a variety of sources, including the practice of slash-
and-burn, when farmers, developers, and loggers clear the land.
These fires have been exacerbated by the worst droughts and some
of the highest temperatures of the century as a result of El
Nino.
According to Mexico's environmental ministry, more than
700,000 acres of national forests, fragile jungle, grassland and
farmland have been consumed by fire this year in Mexico. In
Guatemala, Honduras and Nicaragua, an estimated 2,146 square
miles have burned. In the state of Michoacan, a forest that is
part of the wintering ground of the monarch butterfly has been
threatened as well as some of the Mayan ruins in Guatemala. Many
birds, mammals and rare plants in some of Mexico's fragile
ecosystems have also suffered. The fires have followed much the
same pattern as those that devoured farmlands across South East
Asia last year and sent smoke billowing into Japan, Singapore and
Thailand.
BRAZIL PROTECTS AMAZON FORESTS
On April 29 the president of Brazil announced plans for the
creation and implementation of 25 million hectares (about the
size of the United Kingdom) of new protected areas in the Amazon
rain forest by the year 2000. Brazil is the first country to join
the alliance between the World Bank and WWF for the protection of
at least 10% of the world's forests by the year 2000 (see
December 1997 Biological Conservation Newsletter).
Four new protected areas will be created, two in the Amazon
region and two in the Atlantic Forest. These new areas total
about seven times more than the area of parks and reserves
created in Brazil since 1992. This will almost triple the area
under protection in the Amazon rain forest.
NEW U.S. NATIONAL WILDLIFE REFUGE
On May 16 the Waccamaw National Wildlife Refuge in South Carolina was dedicated, making it the 514th refuge in the United States National Wildlife Refuge System. The refuge covers approximately 49,800 acres of wetland and upland forests that provide habitat for numerous wildlife species including the red- cockaded woodpecker, bald eagle and wood stork, all federally- listed and endangered species. The shortnose sturgeon, another endangered species, inhabits the area's waterways. In addition, the refuge provides valuable breeding habitat for wood ducks and wintering grounds for migratory waterfowl and is recognized as a key area in the North American Waterfowl Management Plan.
UNITED STATES SIGNS DOLPHIN PACT
On May 21, the U.S. Secretary of State, Madeleine Albright,
and representatives from eight other nations (Mexico, Panama,
Ecuador, Nicaragua, Costa Rica, Venezuela, Honduras, and Vanuatu)
signed on to the Agreement on the International Dolphin
Conservation Program. The agreement allows depleted dolphin
stocks to recover, prevents and minimizes bycatch of other marine
life, conserves tuna stocks and tuna fishery, and promotes more
effective tracking of tuna to differentiate between dolphin-safe
and unsafe tuna. According to Roger McManus, president of the
Center for Marine Conservation (CMC), "this is a significant step
toward finally resolving a 25-year conflict about dolphins
drowning in tuna nets. After years of hard work in bringing about
this agreement, the Center for Marine Conservation will now focus
its efforts on making sure the agreement is fully implemented and
enforced."
The Center for Marine Conservation, established in 1972, is
the leading non-profit organization dedicated to the protection,
research, advocacy, and public education of marine conservation
issues in the United States and worldwide. It seeks to protect
ocean environments and conserve global marine diversity. For more

NEW JOURNAL
ECOLOGY LETTERS
In July, Blackwell Science Ltd., in association with the
Centre National de la Recherche Scientifique, is launching a new
journal, Ecology Letters, a forum for the very rapid
publication of original research in ecology. Manuscripts relating
to the ecology of all taxa, in any biome and geographic area,
will be considered, and priority will be given to those papers
exploring or testing clearly stated hypotheses. The journal aims
to publish concise papers that merit urgent publication by virtue
of their originality and general interest and their contribution
to new developments in ecology. Purely descriptive papers or
those that merely extend observations firmly established in one
species to another will not be accepted unless there are strong
reasons for doing so.
Three types of articles will be published in Ecology
Letters: 1) letters, exciting findings in fast-moving areas;
2) ideas, very short essays expressing novel ideas or
correspondence with respect to previous work; and 3) reports,
more lengthy research findings or reviews of subjects of general
interest. For instructions for authors and subscription
information, contact: Blackwell Science, Ltd., Osney Mead, Oxford

NEW PUBLICATIONS
The first Atlas of Australian Birds (1984) was a landmark
event in the history of Australian ornithology. From 1977-81,
over 3,000 birdwatchers collected a total of 3 million records
for the first comprehensive survey of the distribution and
relative abundance of every Australian bird species in a given
period of time. In the first atlas project birdwatchers compiled
species lists for every one-degree latitude/longitude grid block
across the continent. This atlas remains the largest and most
comprehensive wildlife database in Australia.
Over the past 15 years, about 10 million hectares of native
vegetation have been cleared in Australia and at least 150
species and races of birds are threatened with extinction. This
land clearance and other changes have prompted the updated
assessment of the status and distribution of birds, particularly
threatened species, identification of areas of high biodiversity
and conservation importance, and development of conservation
strategies.
Workshops to define methodology and coordinate participation
among birdwatchers were held earlier this year with additional
data collection to begin soon, which will continue for five
years. For more information, contact Birds Australia National
Office, 415 Riversdale Rd., Hawthorn East, Victoria 3123,
Australia. Tel.: 61 3 9882-2622; Fax: 61 3 9882 2677; Web site:

Coastally Restricted Forests, edited by Aimlee D.
Laderman, is the first book to assemble and compare information
on widely dispersed coastal forests of the Northern Hemisphere.
Authorities on each system explore the properties of these
unusual trees and their habitats, and formulate guidelines for
their appropriate management and protection. The thirty-six
contributing authors include natural resource managers and
regulators, ecologists, lumbermen, geneticists, botanists, and
paleontologists. The book draws from work on three continents,
eight countries, and 23 states of the United States. One-half of
the volume is devoted to the seven highly-prized commercially
valuable Chamaecyparis species.
The book is available for $79 (plus $4 for shipping) from
Oxford University Press, 2001 Evans Road, Cary, NC 27513; Tel.:
1-800-451-7556.
FUTURE MEETINGS
August 2-6. The American Institute of Biological Sciences' (AIBS) annual meeting will be held at the Baltimore Convention Center in Baltimore, Maryland. This year's theme is "Managing Human-Impacted Systems."

INFORMATION HIGHWAY HI-LITES
By Gene Rosenberg and
Paula DePriest
In February and March, the Smithsonian Institutions's Botany
Department premiered two World Wide Web sites, on algae and
lichens. Both are accessible from the department's home page
(http://www.nmnh.si.edu/botany). The new Web
sites represent significant advances in the department's efforts
to make information from the Smithsonian's plant collections and
databases available to users around the world.
The algae site is located at http://www.nmnh.si.edu/botany/projects/algae. The Smithsonian
holds one of the largest collections of algae in the world,
including over 183,000 pressed specimens, and 61,600 specimens on
microscope slides, in boxes, or preserved in liquid. The
collection includes algae from marine, estuarine, freshwater,
terrestrial (including caves), and airborne habitats, with
principal holdings of green, brown and red marine macroalgae,
diatoms and cyanobacteria. The collection has a strong
representation from the Gulf of California, Pacific Mexico,
southern and central California and the Channel Islands, the
Galapagos Islands, Aldabra Atoll, and the Caribbean (especially
Florida, Belize, the Bahamas, and Panama).
The algae Web site currently allows searches and data
retrieval for brown algae (Phaeophyta) in the Type Collection.
Efforts are underway to expand direct access to all of the algal
type holdings. Data for the main collection (including the
complete Type Database) can be obtained from in-house staff.
Research interest profiles and regularly updated lists of
publications (including many abstracts) by the staff are
included.
Basic information is also provided on the different algal
groups, their economic uses, collecting and preserving algae,
references for published marine floras, and hypertext links to
other algal sites on the World Wide Web. The new Web site was
developed by Robert Sims and other botany staff. Comments and
suggestions may be sent to Sims or James Norris
(sims.robert@nmnh.si.edu or norris.james@nmnh.si.edu).
The new lichen Web site
(http://www.nmnh.si.edu/botany/projects/lichens) provides an
introduction to the lichen collection and associated research at
the U.S. National Herbarium. The lichen collection, estimated at
250,000 specimens, is the largest in North America and one of the
ten largest in the world. The collection is worldwide in
coverage, and especially rich in North America, emphasizing
Parmeliaceae and Cladoniaceae.
The site was designed to provide electronic access to
databases, keys, descriptions, maps and illustrations that will
be produced in a five year NSF PEET project, Monographic Studies
in the Cladoniaceae, centered at the Smithsonian. Currently, the
site provides abstracts and descriptions of this and related
projects, a biographical sketch and selected bibliography for
Paula DePriest, and links to the Web sites of other researchers.
A link to a sister site maintained by Samuel Hammer at Boston
University will be added.
Currently, there are links to a number of existing
electronic databases, including the type specimen register and
type holdings from Bouly de Lesdain's Lichens du Mexique
(1922). A database of species epithets in the parmelioid genera
will be added in the near future. The site also provides links to
checklists and keys to lichens of the Guianas produced by Harrie
Sipman that reside on the Biological Diversity of the Guianas
Program Web site (http://www.nmnh.si.edu/biodiversity/bdg.htm).
The page "What is a lichen" answers basic questions about
lichens. The Web site was designed by Ellen Farr from materials
provided by Paul DePriest. Comments are welcome: contact
depriest.paula@nmnh.si.edu.
