Two species of pines, Pinus radiata and Pinus muricota, live in the same regions of
California and are capable of forming hybrids under laboratory conditions. However,
they do not interbreed because one releases pollen in February and the other in
April. What genetic isolating mechanism is involved?

Elevated carbon dioxide levels have been shown to contribute to the greenhouse
effect, resulting in an increase in mean global temperature. Ecosystems where the
largest warming has already occurred include snow-covered northern coniferous
