Document Summary

Naming conventions: genus is always capitalized and species is lowercase, always italicized. Long nectar spurs (specialized), evolved over time to hid the nectar so most things cannot get it. con: convergent evolution, analogous traits (not homologous) Spruce tree distribution, glaciers have melted away which has influenced distribution. Frozen frogs: they will freeze as soon as they come into contact with the cold or something frozen, bodily organs will come toegher and the internal liquids center in the body and then freeze. Convergent evolution (evolution of similar traits: same looking plant in california and south africa, one is a cactus and one isn"t, they are not actually the same. Bergmann"s rule: cool habitats, concerned about getting too cold. In more arctic locations, mammals tend to be bigger which lowers their surface : volume ratio: warm habitats, more surface area per volume so you can diffuse the body heat, meaning mammals tend to be smaller.
