In the Mongolian Altai are 9 species: 6 widely distributed in the Palearctic, Deraeocoris annulipes (Herrich-Schaeffer, 1842), Dichrooscytus intermedius Reuter, 1885, Pinalitus rubricatus (Fallén, 1807), Atractotomus mor...
متن کاملNotes on the Cainozoic History of Western Tasmania- " Malanna" Glaciation
The Cainozoic history of the Malanna area included faulting, deposition of sediments by streams or in lakes and swamps, two epochs of planation, and stream erosion. There is no physiographic, depositional or structural evidence for gladation in this area, the type area of Lewis's Malanna Phase of the Pleistocene glaciation. This phase must be considered invalid on the eviaence available in the ...

متن کاملPlasticity in physiological traits in conifers: implications for response to climate change in the western U.S.
Population variation in ecophysiological traits of four co-occurring montane conifers was measured on a large latitudinal gradient to quantitatively assess their potential for response to environmental change. White fir (Abies concolor) had the highest variability, gross photosynthetic rate (Pg), and foliar carbon (C) and nitrogen (N) content. Despite low water use efficiency (WUE), stomatal co...
