Recently, Education Week highlighted the growing national interest in preschool science education (Viadero, 2010, January 20). The story leaves the impression that educating preschoolers in science is poised to become a national movement. Science education for preschoolers is supported in policy by a recent National Research Council (2007) report advocating preschool science instruction, backed...

Endocarpon pusillum is a lichen-forming fungus with an outstanding stress resistance property closely related to its antioxidant system. In this study, thioredoxin (Trx), one of the main components of antioxidant defense systems in E. pusillum (EpTrx), was characterized and analyzed both in transgenic yeasts and in vitro. Our analyses identified that the heterologous expression of EpTrx in the ...

The genus PeniciUium has been separated by Raper & Thom (1949) in their Manual of the Penicillia into fourmajor sections, Monoverticillata, Asymmetrica, Biverticillata-Symmetrica and Polyverticillata. The section Asymmetrica is further divided into five subsections: Divaricata, Velutina, Lanata, Funiculosa and Fasciculata. The subsection Asymnietrica-Fasciculata, in its turn, is subdivided into...

Nine eriophyoid mites, including two new species and five new records, from Iran are described and illustrated. They are Aceria acroptiloni Shevchenko & Kacalev, 1974, rec. n. on Rhaponticum repens (L.) Hidalgo (Asteraceae); Aceria anthocoptes (Nalepa, 1892), rec. n. on Cirsium arvense (L.) Scop. (Asteraceae); Aceria lactucae (Canestrini, 1893), rec. n. on Lactuca virosa L. (Asteraceae); Aceria...

In recent years there has been an increasing interest in several aspects of plant biology in the alpine zone of Mount Kenya. To my knowledge, at least a dozen research projects were carried out between 1977 and 1984. Fortunately, the flora of the region has been the subject of a fine monograph by Hedberg (1957), and the currently available volumes of the Flora of Tropical East Africa (FTEA here...

Photo 1. Our study site was located in the Hengill geothermal area, 40 km east of Reykjavik, Iceland, (64°03′N; 21°18′W, ~360 m.a.s.l.), at base volcanic system. The comprising ~1 km2, includes Fremstidalur (left) and Miðdalur valleys (center right), main vegetation type consists unmanaged, but grazed, subarctic grassland. There are large differences soil temperature over distances only a few m...

A Hereford steer and heifer were used to compare rumen removal rates of forage nutrients from Kansas Flint Hills range over a 2-year period. Rumens were emptied after an overnight fast and the contents sampled, weighed, and returned to the mmen. The cattle were then fed a known amount of range forage and fasted for 12 hours, at which time the rumen evacuation procedure was repeated. Removal rat...

This study was part of the International Tundra Experiment (ITEX) and examined the effects of increased winter snow depth and decreased growing season length on the phenology of four arctic plant species (Betula nana, Salix pulchra, Eriophorum vaginatum, and Vaccinium vitis-idaea) and seasonal nitrogen availability in arctic snowbed communities. Increased snow depth had a large effect on the te...

Agraecia Audinet-Serville, the type-genus of Agraeciini, comprises fifteen species names: thirteen used for extant species, one junior synonym, and one fossil. The species are morphologically very dissimilar, and were collected and described from different localities of the world. The genus was reassessed based on recently collected specimens from Brazil and Argentina as well as museum specimen...
