The purpose of this study was to establish morphometric data for the human scaphoid, document variation in scaphoid dimensions between genders, and to evaluate symmetry in scaphoid measurements between the two sides.
The impact of temperature and gas composition on respiration rates of postharvest produce is well understood, but only a few studies have documented variation in respiration rates of different varieties and at different harvest times of the growing season.
Moreover, it has been difficult to link documented variation in Middle Paleolithic artifact diversity or complexity to environmental factors [9], [10] or even hominin species.
While previous studies have documented variation in migration direction through the Strait of Georgia among species or populations [2], [3], we found intra-population variation among individuals, in three different species.
