Genetic, geographic, and environmental correlates of human temporal bone variation.

Temporal bone shape has been shown to reflect molecular phylogenetic relationships among hominoids and offers significant morphological detail for distinguishing taxa. Although it is generally accepted that temporal bone shape, like other aspects of morphology, has an underlying genetic component, the relative influence of genetic and environmental factors is unclear. To determine the impact of...

Adaptive basis of geographic variation: genetic, phenotypic and environmental differences among beach mouse populations.

A major goal in evolutionary biology is to understand how and why populations differentiate, both genetically and phenotypically, as they invade a novel habitat. A classical example of adaptation is the pale colour of beach mice, relative to their dark mainland ancestors, which colonized the isolated sandy dunes and barrier islands on Florida's Gulf Coast. However, much less is known about diff...

Genetic analysis of environmental variation.

Environmental variation (VE) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either between repeated expressions of the same trait within individuals (e.g. for bilateral traits), in the phenotype of different individuals, where...

Age-structured genetic analysis reveals temporal and geographic variation within and between two cryptic rockfish species

The spatial patterns of genetic structure among juveniles of long-lived species can reveal the extent of interannual and geographic variation in realized larval dispersal as well as the processes that determine ecologically relevant patterns of population connectivity. However, few studies examine this temporal and spatial variation over large portions of a species’ geographic range or between ...

Geographic variation in public health spending: correlates and consequences.

OBJECTIVES To examine the extent of variation in public health agency spending levels across communities and over time, and to identify institutional and community correlates of this variation. DATA SOURCES AND SETTING Three cross-sectional surveys of the nation's 2,900 local public health agencies conducted by the National Association of County and City Health Officials in 1993, 1997, and 20...
