Predicting adaptive evolution under elevated atmospheric CO2 in the perennial grass Bromus erectus

Increasing concentrations of CO2 in the atmosphere are likely to affect the ecological dynamics of plant populations and communities worldwide, yet little is known about potential evolutionary consequences of high CO2. We employed a quantitative genetic framework to examine how the expression of genetic variation and covariation in fitnessrelated traits, and thus, the evolutionary potential of ...

Flavonoids from Ficaria verna Huds.

A phytochemical investigation of the flowers and leaves of Ficaria verna Huds. (Ranunculaceae) yielded four additional known flavonoid compounds including: kaempferol 3-O-beta-D-(6"-a-L-rhamnopyranosyl)-glucopyranoside (nicotiflorin), apigenin 8-C-beta-D-glucopyranoside (vitexin), luteolin 8-C-beta-D-glucopyranoside (orientin) and apigenin 8-C-beta-D-(2"-O-beta-D-glucopyranosyl)-glucopyranoside...

Homo Erectus India

The Quaternary tract of Narmada basin covers an area of abut 12950 sq.km starting from west of Jabalpur (2307790530) to east of Handia (22 29’; 76 58’) for a distance of about 320 km. It is found to be ideal locus of Quaternary sedimentation in Central India, as witnessed by multi-cyclic sequence of Quaternary terraces in the valley. The total estimated thickness of Quaternary sediments in the ...

Pathway HUDs: Are They Viable?

We describe two experiments that examine 3D pathway displays in a head-up location for aircraft landing and taxi. We address both guidance performance and pilot strategies in dividing, focusing, and allocating attention between flight path information and event monitoring. In Experiment 1 the 3D pathway head-up display (HUD) was compared with a conventional 2D HUD. The former was found to produ...

A counterexample to a conjecture of Harrison and Wein 1

For two{station closed queueing networks, Harrison and Wein studied a Reeected Brownian Motion approximation and conjectured an explicit formula for the asymptotic loss of any buuer priority policy. Here we show by explicit solution of two examples that this conjecture is not true for unbalanced networks, even though they are eecient. However, when these networks are balanced, the true asymptot...
