Potamogeton polygonifolius in Newfoundland

DNA barcoding reveals a new record of Potamogeton distinctus (Potamogetonaceae) and its natural hybrids, Potamogeton distinctus × Potamogeton nodosus and Potamogeton distinctus × Potamogeton wrightii (Potamogeton ×malainoides) from Myanmar

Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...

Vehicle-moose accidents in Newfoundland.

During 1987 and 1988, in Newfoundland, there were 661 motor-vehicle accidents involving a moose; 133 people were injured and three died. This constitutes a major problem for the provincial health-care system. In 95 per cent of the patients who were involved in fifty-five primary collisions (the vehicle hit only the moose), the injury-severity score was less than 9 (mean and standard deviation, ...
