It has been proposed that predation pressure on nests was the major selective force leading to cave breeding and roosting [20].
Geographic variation in the thermal environment impacts a broad range of biochemical and physiological processes and can be a major selective force leading to local population adaptation.
Mutation and recombination are the major evolutionary forces leading to emergence of genetically diverse EV71 variants that have accounted for the recurrent HFMD outbreaks.
A magnetic field H y = 0.4 T was placed perpendicular to the direction of the current (I x ), so that the majority charge carriers (electrons, e−) flowing in the x-direction will be swept down by the effect of the resulting Lorentz force, leading to a major accumulation of valance band holes (h+) at the HF-silicon interface, promoting the reaction.
Perceived force to move against flipping was rated qualitatively on a three-point scale (0=no force; 1=weak torque force leading to reorientation; 2=strong torque dislodgement forcing reorientation).
Now, the Nusra Front has become a major force on the battlefield, leading other rebel groups in more conventional fights.
Adaptation to diverse ecological habitats is a major force driving population differentiation, leading to the evolution of reproductive isolation, and ultimately speciation (Schluter, [ 1, 2]; Coyne & Orr, [ 3]; Rundle & Nosil, [ 4]; Sobel et al.[ 5]).
COPENHAGEN — Widely recognized as Denmark's leading composer, Poul Ruders established himself as a major force in opera with "The Handmaid's Tale," a harrowing treatment of Margaret Atwood's futuristic best-seller that received its premiere at the Royal Danish Opera in 2000.
But that would seem to beg the question of why the UK became the world's leading nation for synth-pop, and later the major force in electronic dance music all through the 90s.
