SummaryIn northern Victoria Land (continental Antarctica, between 72° and 76°S, 162° and 169°E), 18 moss samples have been collected and analysed for the presence of pollen. In turfs and cushions of 8 different moss species, at least 27 pollen taxa could be identified. The pinus-type pollen and those of grasses were very common. More than 60% of the total grains were damaged or could not be identified. There is evidence that the Antarctic continent could act as a sink for wind-transported… 
Genetic diversity in the moss Pohlia nutans on geothermal ground of Mount Rittmann, Victoria Land, Antarctica
The only known population of the moss Pohlia nutans in continental Antarctica occurs on geothermally heated ground of volcanic Mt. Rittmann in northern Victoria Land, and appears to be derived from a single immigration event followed by vegetative growth, mutation and dispersal.
Pollen Dispersal and Deposition on the Quelccaya Ice Cap, Peru
The relatively young science of tropical ice-core palynology has proven effective in the study of paleoenvironments by its ability to produce long-term and highresolution paleoclimatic data. However,
Trajectories associated to regional and extra-regional pollen transport in the southeast of Buenos Aires province, Mar del Plata (Argentina)
Backward trajectories of Celtis and Nothofagus pollen grains trapped over a meteorological station outside Mar del Plata City were calculated using the regional hybrid model developed by the NOAA and the data of the NCEP filed in the NOAA server and showed that the observed trajectories agree with the location of vegetation sources of the collected tree species.
Microorganisms in the atmosphere over Antarctica.
The behaviour of microorganisms in the Antarctic aerial environment is examined and the extent to which these microorganisms might influence Antarctic microbial biodiversity is examined.
Plants and Lichens in the Antarctic, Their Way of Life and Their Relevance to Soil Formation
In classical terms, soil is a product of rock weathering and influences of soil organisms, dead and transformed organic substances, water and air (Scheffer and Schachtschabel 1984). In other words,
Emerging spatial patterns in Antarctic prokaryotes
It is clear that spatial patterns of Antarctic prokaryotes can be unique at local scales, while the limited evidence available to date supports the group exhibiting overall regional biogeographical patterns similar to the eukaryotes.
A methodological proposal for the recovery of palynomorphs from snow and ice samples
The procedures for a set of techniques to recover grains of pollen 26 and spores from liquid samples are described. Liquefied samples of matrices, such as melting lakes, snow and ice, can provide a
Terrestrial Antarctic ecosystems in the changing world: an overview.
Although the Antarctic has avoided the worst effects of alien species, its future seems endangered due to increasing natural and man−made pressures. Rapid changes in three major environmental


Pollen and spores transport into the Antarctic
The low frequency of pollen in Wilkes Land indicates a separation of this part of Antarctica from propagule exchange with other continents and the cryptogams of most of the Antarctic continent may represent a largely relictual flora which survived in ice-free refugia.
Exotic Pollen and Long-Distance wind Dispersal at a Sub-Antarctic Island
Abstract Exotic pollen grains on Marion Island (southern Indian Ocean) make up ±1.2% of the spectra recorded in samples of various surface soils, peat profiles and a moraine matrix. They consist
Long-distance pollen transport over the southern Tasman Sea: evidence from Macquarie Island
Abstract Numerous exotic pollen and spore types occur in Holocene lake deposits on Macquarie Island. Most are con~idered to be derived from sources in the south-east Australian region. Myrtaceae
Pollen morphology of Myrtaceae from the south-west Pacific area
The pollen grains of 300 species of 71 genera of the family Myrtaceae have been examined and their characteristic features summarized in tabular form and the significance of pollen characters for distinguishing genera and species within the family is discussed.
Postglacial Pollen Diagrams from South Georgia (Sub-Antarctic) and West Falkland Island (South Atlantic)
Six pollen diagrams are presented, five from South Georgia, and one from near Port Howard, West Falkland Island, which are the first published for either island and establish the status of Montia fontana, Sphagnum fimbriatum and Poa annua as being native and as being a probable introduction since c.
Taxonomic and ecological investigations of algae on steam-warmed soil on Mt Erebus, Ross Island, Antarctica
Micro-algae and protonematal moss grow on steam-warmed, fumarolic ground at approximately 3500 m altitude on the active volcano Mt Erebus and the algal flora comprises four species of Cyanobacteria and 11 species and two varieties of Chlorophyta, which are typical mesophiles.
Biology of Polar Bryophytes and Lichens
The study of plant ecology in these areas has advanced dramatically and the results synthesised here contribute to a general understanding both of polar ecosystems and of the environmental relationships of bryophytes and lichens.
Mature Pollen and its Impact on Plant and Man
The ultimate goal of the pollen grain is to contribute to zygote formation, but many more pollen grains are processed than are necessary for the fertilization of all female receptive cells, at least in most of the angiosperm plant species.
The biota and environment of fumaroles on Mt Melbourne, northern Victoria Land
The biota and environment of fumarolic ground close to the summit of Mt Melbourne are compared with those found at other thermal localities in Antarctica and the dispersal of propagules to these areas is discussed.
