HETEROLOGOUS EXPRESSION OF GENES MEDIATING ENHANCED FUNGAL RESISTANCE IN TRANSGENIC WHEAT


Ice and mineral licks used by caribou in winter

In winter, barren-ground caribou obtain minerals from ice and soil licks.Between December and April we have seen caribou cratering on the surface of frozen lakes and licking the ice.Ice samples from eight Stove Temperature Sensor licks on four lakes contained concentrations of calcium, magnesium, sodium, potassium, phosphorus, chloride and sulphate
