Summary
This Project is a part of the Framework Project: BIODIVERSITY AND ECOLOGY ON
ANTARCTIC CONTINENTAL ENVIRONMENTS' ALGAE

This project continues the one initiated by our research group in 1989, on
taxonomy and ecology of Antarctic freshwater algae. It aims to obtain a
thorough survey of the algal biodiversity in areas of Maritime Antarctica.

Within ... this framework, the structure and composition of the algal communities
epiphytic on aquatic mosses in lakes from Potter Peninsula (25 de Mayo Island,
South Shetland Islands) will be studied. The environmental factors influencing
the distribution of epiphytic algae along a transect from the water body to the
surrounding mosses will be analyzed. Also, biogeographical links will be sought
between the diatoms epiphytic on mosses from Subantarctic Islands and Maritime
Antarctic. In order to attempt an integrated study of the trophic interactions
in this particular type of freshwater environment, other algal communities
(phytoplankton, epilithon) as well as the bacterioplankton and associated
microfauna will also be analyzed.

PICTA-07-2004 "Biodiversidad y ecologia de algas epifitas sobre musgos en los
lagos de peninsula Potter (Shetland del Sur, Antartida)", Dir Alicia Vinocur:

Este proyecto es continuacion del iniciado por nuestro grupo de investigacion
en 1989, sobre taxonomia y ecologia de algas de agua dulce antarticas. El mismo
apunta a obtener un exhaustivo relevamiento de la diversidad algal en zonas de
la Antartida Maritima (insular y peninsular).

En el marco de este proyecto, se estudiaran la composicion y estructura de las
comunidades de algas epifitas sobre musgos acuaticos en lagos de Peninsula
Potter (Isla 25 de Mayo, Shetland del Sur). Se analizaran los factores
ambientales que inciden en la distribucion de estos organismos a lo largo de
una transecta desde el seno del cuerpo de agua hasta los musgos de la
periferia. Tambien se tratara de establecer relaciones biogeograficas entre las
diatomeas epifitas sobre musgos de zonas subantarticas y de la Antartida
Maritima. Con el objetivo de encarar el estudio integrado de las interacciones
troficas de este tipo particular de ambiente lacustre se analizaran las otras
comunidades algales presentes (fitoplancton y epiliton), el bacterioplancton y
la microfauna Asociada.
