PROJECTS
In an ongoing effort to preserve and promote biodiversity, TCA
scientists are locating and identifying many rare and endangered
animals in various habitats around the world, discovering new
species and species previously thought to be extinct.
Our record of
discoveries includes more than 20 new species of mammals, reptiles,
and amphibians. Dozens of animals thought to be lost or extinct have
been rediscovered, among them Darlington's Flat Beetle, Walsingham's
Virgin Moth, the spectacular Everett's Flying Dragon, and the Silver
Rice Rat - the latter declared extinct and rediscovered twice.
Hundreds of new insect species have been discovered as well.
If you
would like to be involved in this type of research and if you like to
travel, please contact us for more information. Perhaps you will be
joining us on our next expedition!
Narragansett Bay Coyote Study (NBCS) - This study of
coyotes on Conanicut and Aquidneck Islands will improve the quality of
public information about Rhode Island's coyotes as well as the quality
of public outreach through valid scientific sources. Through extensive
cooperation with local school systems, data created by this study will
be immediately incorporated into the schools' lesson plans, and school
children will be able, through the Internet, to check the coyotes'
movements daily and learn about their behavior and habits. In the final
stage of NBCS we will create Management Strategies for Coyotes on
Conanicut and Aquidneck Islands.
Narragansett Bay - The Conservation Agency Circuit
Biologist Program provides continuity contributing to a cohesive
strategy for managing threatened species or habitats on Aquidneck and
Conanicut Islands, increases data acquisition, and allows for a unified
and centralized system of data management.
The Conservation Agency has provided consulting for land trusts in
Newport County over the past decade documenting environmental conditions
and making management recommendations concerning native plants, animals,
wetlands, habitat corridors, rare species, and invasive exotic species.
Turks & Caicos Islands - The Big Ambergris Cay iguana
relocation project conducted by the Department of Environment and
Coastal Resources, Turks and Caicos Island (TCI), The Conservation
Agency (TCA), and the Denver Zoo continues to progress well. Since our
first translocation in November 1999, we have relocated a total of 404
iguanas.
We continue to collect data on iguana habitat use, burrow location, home
range dynamics, and information on reproduction and recruitment of
young. Since all Long Cay founders are PIT tagged, and dispersal to the
cay is unlikely, we can be reasonably sure that untagged iguanas were
born there. In January 2001 we confirmed the presence of Long Cay
hatchlings. Volunteers are always welcome and should contact Numi
Mitchell regarding expedition schedules.
Flamingo Reintroduction to Anegada, BVI - Dr. James (Skip)
Lazell first recognized the potential for successful reintroduction of
flamingos to the salt ponds of Anegada in the early 1980's. Cooperating
organizations and individuals, including the Bermuda Aquarium Museum and
Zoo (BAMZ); Richard Winchell, Mocata Corporation; Dr. Henry Jarecki, the
BVI National Parks Trust (NPT) Director; Nick Clark; and others moved a
small test group from Bermuda to the small salt pond on Guana Island.
The Guana transplant has been successful but the flock is too small to
breed. Therefore we got another batch of 18 flamingos and settled
them on Anegada in the BVI. This flock attracted four more wild
birds and began nesting. By 2007 the Anegada flock had expanded to
about 200 flamingos. Details of the story are presented in
Lazell's book, Island - Fact and Theory in Nature. See
Publications.
Western Hemisphere - The Conservation Agency has supported
projects in the Western Hemisphere from Newfoundland to Brazil. In the
Canadian Maritimes and New England our subjects have been whales, marine
and salt-marsh turtles, vernal pond wildlife, salamanders and acid rain,
wetlands protection, and coastal island biogeography.
Asia - Since 1980 significant ongoing research has drawn us
to the islands of the South China Sea. Here we have discovered many new
populations, several new species of land vertebrates, and have
documented life histories of threatened species such as Romer's frog,
white-headed blindsnake, and the Chinese pangolin (a scaly ant-eating
mammal). We have concentrated efforts on islands in the South
China Sea including the geologically ancient island of Nan Ao, in far
eastern Guangdong Province, China. On Nan Ao we discovered many
populations of species previously known only from inland, upland, and
central China. Often these isolated Nan Ao populations are
replaced by more tropical relatives on the adjacent mainland. This
pattern, dubbed "Austro-boreal disjunction", is strikingly like that
observed in species or subspecies found in the Florida Keys and then
again in northern Florida or Georgia. Austro-boreal disjunction
has become a topic of great interest in biogeography.
Australia and the Pacific - We successfully documented the
migratory route of the orange-bellied parrot, extended the known ranges
of dozens of species from the red-necked kangaroo to Peripatus insignis
(a bizarre primitive invertebrate), and collected life-history data on
marsupial carnivores such as swamp antechinus, white-footed dunnart, and
quoll. Further, we produced the first-ever demographic study of the
Tasmanian devil. On New Caledonia, in the Coral Sea, we have
concentrated our efforts on lizards on the offshore islets around Grande
Terre, the largest island. We discovered 47 previously
undocumented populations, many of rare or little-known species. We
added another two dozen significant range extensions for species on the
Grande Terre main.
