Yet, it is not always clear how different measurements relate to different hypotheses of the adaptive function of coloration, or the life-history variability that underpins the pigments themselves.
Here, we quantify the influences of oceanographic flow and early life-history variability on the population genetic structure of C. gunnari and N. rossii in the Scotia Sea.
Local adaptation may be inferred from neutral genetic structure coincident with habitat or life-history variability (Olsen et al. 2011; Blankenship et al. 2011).
The frequency of such follow-up is not established and is likely to depend on the natural history and variability of patients' health status and the availability and use of appropriate treatments.
The significance and natural history of variability in Aβ tissue concentration in the lens and its possible relationship to the brain in DS are subjects of ongoing investigation.
Validation of a marker for use in a population requires attention to issues of background prevalence, sample size, natural history, persistence, variability, confounding factors, and predictive value.
The numerical models projected the observed population genetic structure of both species with a high degree of accuracy, suggesting that parameters used in the model (principally early life history and variability in ocean flows) were a reasonable approximation of reality.
All studies on predicted climate change for the area agree that: This in turn will contribute directly to water shortages; There is little agreement on changes in rainfall, but most models suggest decreases are possible; Based on past history, climate variability (inter-annual, seasonal and spatial) will contribute to water shortages and land degradation.
In conclusion, complex patterns of population dynamics, seasonal variation in life histories, and variability of behaviour due to asset-protection may cause complex seasonal behavioural dynamics in a population.
Finally genotype-by-environment interactions can also account for variability in life-history strategies [18].
