SEASONAL VARIATION AND EFFECTS OF WINTER TICKS (DERMACENTOR ALBIPICTUS) ON CONSUMPTION OF FOOD BY CAPTIVE MOOSE (ALCES ALCES) CALVES
Effects of season and level of winter tick (Dermacentor albipictus) infestation on food intake by moose (Alces alces) were evaluated using 4 heavily infested calves (41,000 larval ticks), 4 moderately infested claves (21,000 larval ticks) and 4 uninfested calves. Food intake for all moose averaged 0...
