Team Leader Dr. Antônio Batista Pereira Vice-Team Leader Dr. Maria Virgínia Petry Introduction The module theme “Global Change Impact on the Antarctic Environment,” which investigates the impact of global change on terrestrial environment, develops a set of research areas thaw of Antarctica, to obtain data which help to explain the effects of environmental change on biological communities. Besides trying to understand the dynamics of populations and their relationships. The study of vegetation develops surveys to describe and map the plant communities in ice-free areas, aiming to understand their evolution, the relationships with the soil microbial community and birds colony and the emission of greenhouse gases that contribute to global warming. With the data obtained are expected to contribute to the monitoring of ice-free ecosystems, assessing the possible environmental impacts by human occupation or natural phenomena. Based on this objective, was chosen two indicators, “plant biodiversity” and “plant cover”. The use of “plant biodiversity” as an indicator of environmental impacts, based on the fact that most plants that grow in ice-free areas of Antarctica can be classified into ornithocropróphylous or ornithocopróphobous. Soon, all changes that occur in bird populations will be reflected in the biodiversity of plant communities. The “plant cover” is important because the global changes are altering the ice cover in Antarctica, contributing to changing environments and expansion of ice-free areas. With the data obtained will be possible to identify, locate and describe each plant every community. Through georeferencing of each community will be possible to prepare maps of vegetation, which can be compared with those developed in the period 1995- 2012, thus allowing the assessment of the evolution of each community, and contribute to building methodologies for monitoring plant communities of ice-free areas. The study of soil microbial communities and the gases flow that contribute to global warming started in 2010/2011 will continue collecting data in the same areas associated with working on vegetation. The main goal of studying the distribution and dynamics of seabird populations is understand the complex relations between populations and oceanic factors. Seabirds are useful as tools for understand and monitor the effects of global change whereas they provide a link between marine and terrestrial environments. It is, many population measures we obtain in land are reflection of conditions that the birds are experiencing off sea. Sea climate and productivity can affect the foraging efficiency of seabirds and affect their breeding decisions. Seabirds are on the top of food webs, then, they reflect the status of all the levels above. As they rely on sea productivity – Zooplankton, Krill, fishes and squids – any abrupt changes on lower levels of the food webs can affect demography parameters such as number of breeding pairs, survival, breeding success, breeding desertion rates, and so on. All factors are connected: the productivity on Antarctic waters clearly depends on the balance of sea-ice-sheets dynamic which is correlated to sea-surface warming, sea level pressure and wind regime shifts. All those changes can directly or indirectly influence seabirds. As a linkage between sea and land, seabirds drive the structure of terrestrial communities, be they microbial, plants, lichens or invertebrates, by “fertilizing” soils and inputting energy from the ocean on the land. Measure all those connections is necessary so the whole picture of terrestrial communities responses to global changes can be achieved. Furthermore, seabirds can forage far from breeding grounds, many reaching subantarctic waters at north or going south into the Antarctic Circumpolar Currents, as demonstrated by the study “Oceanic habitat use of an Antarctic Southern Giant Petrel population during breeding period”. Through geolocation techniques we were able to access the ocean areas used by the species. Giant Petrels Science Highlights - Thematic Area 2 | 47
