Topical application of ice-nucleating-active bacteria decreases insect cold tolerance
The majority of overwintering insects avoid lethal freezing by lowering the temperature at which ice spontaneously nucleates within their body fluids. We examined the effect of ice-nucleating-active bacteria on the ... -
Using microrespirometers to measure oxygen consumption by insects and small invertebrates.
A variety of physiological studies require the measurement of oxygen consumption. Unfortunately, the techniques for measuring respiration rate often require expensive equipment or difficult procedures that are not available ... -
Winter biology & freeze tolerance in the goldenrod gall fly
Birds migrate. Bears hibernate. Turtles and frogs retreat to the bottom of lakes. Most animals must avoid harsh winter conditions; few can survive freezing. Larvae of the goldenrod gall fly (Eurosta solidaginis), can ...
