Paternal Mitochondrial Transmission in Intra-Species Caenorhabditis briggsae Hybrids

To study mitochondrial-nuclear genetic interactions in the nematode Caenorhabditis briggsae, our three laboratories independently created 38 intra-species cytoplasmic-nuclear hybrid (cybrid) lines. Although the cross design combines maternal mitotypes with paternal nuclear genotypes, eight lines (21%) unexpectedly contained paternal mitotypes. All eight share in common ancestry of one of two ge...

way to a further divergence between medical researchers, such as comparative anatomists, and clinical practitioners during the era of university reform after the breakup of the Holy Roman Empire and the ReichsdeputationshauptschluJ3 of 1803. The competing cultural politics of the German states provided another public sphere for this theory-practice division. In his conclusions Broman notes that...

Memoirs on Highway Traffic Flow Theory in the 1950s

T has been a revival of interest in traffic flow theory in the late 1990s, mostly because vehicle detectors have been installed at many highway locations throughout the world to record the passing of vehicles. The purpose of these detectors is to monitor congestion and provide information for possible control or to advise motorists of possible alternative routing. To understand the consequences...

DIFFERENTIAL IMpACTS OF EChINOID gRAzERS ON CORAL RECRUITMENT

It has been argued that recent phase-shifts towards algal dominance in the Caribbean could have a profoundly negative influence on the future survival of settling corals. In the lower Florida Keys, USA, we used field surveys in areas with recovering populations of the formerly abundant herbivorous black urchin Diadema antillarum (philippi, 1845) and comparatively stable populations of the urchi...
