Population Ecology, Community Ecology.

1. Pick a plant and an animal and tell me how these how plants and animals arrive, find, migrate or develop their habitat, respond to the food chain, climate and other living and non living factors. Give an example or short explanation of each. This will show you how the ecology works together

2. Ecology is called nature's laboratory. Why? What causes species distribution?

3. What is the current plight of the honey bee? What will be the outcome?

4. What causes extinction? What enhances resilience? Give examples of each.

The creosote bushes are the most common plants in the desert habitat ( Sonoran, Chihuanhuan and Mojave Deserts) of North America. The related species are also found in South America (Southern Peru, Bolivia, and Argentina). (1) Creosote bushes originated in South America and spread on to North America during the Pleistocene era at about 1 million - 10,000 years ago. (1) They are often found on dry, flat terrain where there are rainfall of about 8-10 cm per year. (1) They are like cactus found in the Chihuanhuna Desert and in the Sonoran Desert.

Creosote bush is very drought tolerance land plant of North America, and they can live without water for about 2 years. They usually shed their leaves, but sometime retain them and allowing them to dry to golden brown (1). The leaves can synthesize sugars which allow the the plant to live long in the desert. There are several factors that allow them to tolerate drought condition: 1) their leaves have small surface area that prevent water loss, 2) their leaves have thick, waxy cuticle with high stomatal resistance 3) their leaves has high water potentials.
They live for a long time up to 100-200 years. They have the same genetic make-up and seem to have the same uniformity in appearance. For many centuries, new shoots continually produced ...
