Abstract Understanding the mechanisms of adaptation to spatiotemporal environmental variation is a fundamental goal of evolutionary biology. This issue also has important implications for anticipating biological responses to contemporary climate warming and determining the processes by which invasive species are able to spread rapidly across broad(More)
The objective of the present study was to determine the amount of agreement among three clinicians in the clinical assessment of dorsal mobility of the foot's first ray and the agreement between their assessments and that of a mechanical device designed to quantify first-ray mobility. Sixty feet from 30 individuals evaluated clinically by three health-care(More)
BACKGROUND Hypomobility and hypermobility of the first ray have been implicated in the literature as a primary cause of mechanical foot problems because of proposed obligatory and compensatory movements. Despite these theoretical links, research is sparse regarding the effect on kinematic and plantar pressure patterns as a result of altered first ray(More)
Emerging and re-emerging vector-borne diseases represent an increasingly significant public health challenge. While geographic variation among populations of vector species for susceptibility to pathogen infection and vector competence has been thoroughly documented, relatively little attention has been devoted to understanding the ultimate evolutionary(More)
Aedes albopictus (Skuse) (Diptera: Culicidae) invaded the United States in 1985 and spread rapidly across eastern North America, whereas Aedes japonicus (Theobald) invaded and became established in the United States more recently (1998). The two species may co-occur in container habitats, and they are of potential public health concern as arbovirus vectors.(More)
BACKGROUND The purpose of this study was to determine the interrater reliability of visual rating of forefoot frontal plane deformities among clinicians with different training. METHODS Thirty individuals (16 men and 14 women) between the ages of 22 and 52 years of age participated in the study. None of the patients had a history of congenital deformity,(More)
