Warming is a trend that is set against the underlying variation in natural climate.
Although exact mechanisms underlying variation of [11C]HMS011 metabolism among subjects remain unknown, it is likely related to individual variation of activity of hepatic cytochrome system that is involved in the metabolism of this drug.
It is not clear if these state-level differences are due to underlying variation in medical coding practice, time period, population rates for SUDs and/or utilization of mental health services, or other factors.
Moreover, anatomical structure underlying variation in leaf density and thickness may differ depending on the nature of the species and their environment (Garnier and Laurent 1994; Van Arendonk and Poorter 1994; Poorter et al. 2009).
The field of plant evolutionary development (evo-devo) integrates molecular genetics, phylogenetics, comparative morphology, and modern evolutionary theory to understand developmental and genetic changes underlying variation in plant form and function.
We performed the first genome-wide association study of Cloninger's temperament scales in a sample of 5117 individuals, in order to identify common genetic variants underlying variation in personality.
Variation in individual response thresholds may reveal underlying variation in queen-worker reproductive conflict.
However, the underlying variation in this duct has not been assessed across populations and species.
However, current evidence does not support plasticity as a major factor underlying variation in trophic morphology for female guppies.
A matrix of pairwise correlations among significant transcripts was constructed in an attempt to elucidate the genetic networks underlying variation in individual retinue response.
An implication of more genes underlying variation in a particular trait is systematically lower additive genetic variance for larger networks at simulation initiation [31].
