Editor's Notes
- Just the bare bones of it…folks!! I think you notice some skeletal similarities.... Bones of the wing are the same as those in the human arm and hand, but the finger bones are very long …
- Life in America would not be the same without bats. Desert ecosystems rely on nectar-feeding bats as primary pollinators of giant cacti, including the famous organ pipe and saguaro of Arizona. They also assist in seed dispersal for these plants. Note: The turquoise colored footnotes in this presentation are quoted from Important Bat Facts – a pamphlet published by Bat Conservation International **Bat Fact --Tequila is produced from agave plants whose seed production drops to 1/3000th of normal without bat pollinators. You may want to think of the long-nosed bats as the tequila connection.
