Life history patterns of modern and fossil Mercenaria spp. from warm vs. cold climates

response of modern and old wheat cultivars improved to fit moderate, cold and warm climates of iran to source strength reduction

source limitation during grain filling is important for both management and breeding strategies of grain crops. there is little information on the sensitivity of grain yield to various source-sink ratios in various wheat (triticum aestivum) cultivars. the objective of the current study was to evaluate the response of grain yield as well as yield components to different source-sink ratios during...

“icehouse” (cold) Climates

Earth's climate has changed, within life-sustaining bounds, from warm to cool intervals, on scales from thousands to hundreds of millions of years. In the Phanerozoic Eon there have been three intervals of glaciation (Ordovician, Carboniferous and Cenozoic) lasting tens of millions of years, with ice down to sea level at mid-latitudes (Frakes et al., 1992; Crowell, 1999). These cool " ice-house...
