The Trials of Scipio
Introduction I teach two sections of high school statistics at the North Carolina School of Science and Mathematics. Students here doing research projects in biology occasionally need help with the design of their experiments and the analysis of their data, and my statistics colleagues and I may be called upon to provide this help. Two years ago I worked with a student named Tommy Miller, who w...
متن کاملRevised Host Range and Studies on the Life Cycle of Longidorus africanus.
The host range of Longidorus africanus was demonstrated to be much wider than previously reported. All commercial crop plants tested, except two of four crucifers, were hosts of L. africanus. The nematode was widespread in fields, and soil type did not appear to be related to its distribution. The minimum time to complete a life cycle was 9 weeks at 28 C in a plant growth chamber. Field observa...
متن کاملMetacarpal proportions in Australopithecus africanus.
Recent work has shown that, despite being craniodentally more derived, Australopithecus africanus had more apelike limb-size proportions than A. afarensis. Here, we test whether the A. africanus hand, as judged by metacarpal shaft and articular proportions, was similarly apelike. More specifically, did A. africanus have a short and narrow first metacarpal (MC1) relative to the other metacarpals...
متن کاملComment on “Human-like hand use in Australopithecus africanus”
Skinner and colleagues (Research Article, 23 January 2015, p. 395), based on metacarpal trabecular bone structure, argue that Australopithecus africanus employed human-like dexterity for stone tool making and use 3 million years ago. However, their evolutionary and biological assumptions are misinformed, failing to refute the previously existing hypothesis that human-like manipulation preceded ...
متن کاملEmergomyces africanus in Soil, South Africa
We detected Emergomyces africanus, a thermally dimorphic fungus that causes an HIV-associated systemic mycosis, by PCR in 18 (30%) of 60 soil samples from a wide range of habitats in South Africa. Direct and indirect culture techniques were unsuccessful. Experimental intraperitoneal inoculation of conidia induced murine disease.
