First fossil finds of some Australian Bryozoa (Cheilostomata)

The abundant fossil record of well-preserved Bryozoa in samples from the Tertiary of Victoria and South Australia includes some \u27first fossil finds\u27 which are recorded here. Several are of species known from the Recent of the Australian or Indo-West-Pacific regions, but some represent genera with a much wider temporal and geographical range. Of the 11 species illustrated, six are known, or may be inferred, to have inhabited \u27sand fauna\u27 environments. Specimens of one species are complete enough to allow its formal description as Chlidoniopsis inopina sp. nov. <br /

Trends in Antarctic ecological research in Latin America shown by publications in international journals

Antarctica is a highly interesting region for ecologists because of its extreme climatic conditions and the uniqueness of its species. In this article, we describe the trends in Antarctic ecological research participation by Latin American countries. In a survey of articles indexed by the ISI Web of Science, we searched under the categories &#x201C;Ecology,&#x201D; &#x201C;Biodiversity Conservation&#x201D; and &#x201C;Evolutionary Biology&#x201D; and found a total of 254 research articles published by Latin American countries. We classified these articles according to the country of affiliation, kingdom of the study species, level of biological organization and environment. Our main finding is that there is a steady increase in the relative contribution of Latin American countries to Antarctic ecological research. Within each category, we found that marine studies are more common than terrestrial studies. Between the different kingdoms, most studies focus on animals and most studies use a community approach. The leading countries in terms of productivity were Argentina, Chile and Brazil, with Argentina showing the highest rate of increase
