Document Summary

If temperature increases, development should be faster. Developmental time (degree in c * days) Time for development expressed in relation to temperature. Time for development expressed with relation to temperature (zygote to adult in ambient temperature) Developmental time (deg c* days)= time (days)*(average ambient temperature (deeg c)-threshold temperature for development (deg c)) Determine the most sensitive phase of life cycle (shelford"s law) Determine the range of tolerances during this phase. Use a map of the geographic distribution you are studying, measure temperature inside and outside of where species occurs. Microclimate: temperature in the kinds of places the species like to live. Establish cause and effect by experimental manipulation. Northern limit of geographic distribution: 4 deg c minimum temperature isotherm. Northern edge of its geographic distribution: 4 deg c average january temperature. Not flowering and setting seeds below this temperature. Send the night in holes in trees. Coniferous forest extend farther north chickadee"s distribution than black capped.
