1.  Drought meets acid: three new genera in a dothidealean clade of extremotolerant fungi 
Studies in Mycology  2008;61:1-20.
Fungal strains isolated from rocks and lichens collected in the Antarctic ice-free area of the Victoria Land, one of the coldest and driest habitats on earth, were found in two phylogenetically isolated positions within the subclass Dothideomycetidae. They are here reported as new genera and species, Recurvomyces mirabilis gen. nov., sp. nov. and Elasticomyces elasticus gen. nov., sp. nov. The nearest neighbours within the clades were other rock-inhabiting fungi from dry environments, either cold or hot. Plant-associated Mycosphaerella-like species, known as invaders of leathery leaves in semi-arid climates, are also phylogenetically related with the new taxa. The clusters are also related to the halophilic species Hortaea werneckii, as well as to acidophilic fungi. One of the latter, able to grow at pH 0, is Scytalidium acidophilum, which is ascribed here to the newly validated genus Acidomyces. The ecological implications of this finding are discussed.

2.  Resistance of Antarctic black fungi and cryptoendolithic communities to simulated space and Martian conditions 
Studies in Mycology  2008;61:99-109.
Dried colonies of the Antarctic rock-inhabiting meristematic fungi Cryomyces antarcticus CCFEE 515, CCFEE 534 and C. minteri CCFEE 5187, as well as fragments of rocks colonized by the Antarctic cryptoendolithic community, were exposed to a set of ground-based experiment verification tests (EVTs) at the German Aerospace Center (DLR, Köln, Germany). These were carried out to test the tolerance of these organisms in view of their possible exposure to space conditions outside of the International Space Station (ISS). Tests included single or combined simulated space and Martian conditions. Responses were analysed both by cultural and microscopic methods. Thereby, colony formation capacities were measured and the cellular viability was assessed using live/dead dyes FUN 1 and SYTOX Green. The results clearly suggest a general good resistance of all the samples investigated. C. minteri CCFEE 5187, C. antarcticus CCFEE 515 and colonized rocks were selected as suitable candidates to withstand space flight and long-term permanence in space on the ISS in the framework of the LIchens and Fungi Experiments (LIFE programme, European Space Agency).

3.  Health status indicators for the year 2000: projections for Allegheny County, Pennsylvania. 
Public Health Reports  1993;108(6):711-715.
A consensus set of health status indicators was released in July 1991 by the Centers for Disease Control and Prevention for use by public health officials at the Federal, State, and local levels in identifying and monitoring issues of public health importance. These health status indicators have been projected for the Year 2000 in Allegheny County, PA, with linear regression analyses of historical data. Indications are that mortality rates for black infants, breast cancer mortality, suicide, lung cancer mortality, incidence of acquired immunodeficiency syndrome, and the number of measles cases likely will not meet the year 2000 targets in Allegheny County. These data will prove useful in monitoring progress towards the year 2000 objectives and provide comparative data for other geographic areas of the United States with similar demographic characteristics.
