The impact of climate and ocean circulation changes on marine carbon and nitrogen cycling was investigated for a period covering the Late Ordovician Hirnantian glaciation. Three sections were studied: two from Nevada, one proximal and one distal; and

International audience; Abstract Males of sibling orchid bees Euglossa viridissima and Euglossa dilemma are morphologically cryptic, except for the number and shape of mandibular teeth. An alternative morph of E. viridissima has a third tooth similar

Phenotypic plasticity is a developmental process that plays a role as a source of variation for evolution. Models of adaptive divergence make the prediction that increasing ecological specialization should be associated with lower levels of plasticit

A number of statistical tests have been developed to determine what type of dynamics underlie observed changes in morphology in evolutionary time series, based on the pattern of change within the time series. The theory of the 'scaled maximum', the '

T present trend to more severe operating conditions in turbine engines will require fairly sophisticated cooling schemes. The thermal barrier, a low conductivity coating, is a means of reducing the cooling requirements. The chief benefit of a thermal
