Document Summary
Bis 2b lecture #1 - intro to ecology and evolution. The study of interactions between organisms and their environment; the goal being to determine the distribution and abundance of species. A single change in any environmental factor will most likely have a direct or indirect effect on all life forms within a habitat, including humans. Potential to develop the ability to predict future size and distribution of populations (in short, a scientific way of telling the future). Basic math and a bit of calculus. Understanding of complex interactions that affect all life. How your environment directly and indirectly affects you. The changing in properties of populations spanning over generations. Different reproductive rates of different alleles spur evolution. Ecology and evolution mutually influence each other. Ecology influences evolution through changing habitats and environmental factors. Evolution influences ecology because a species" characteristics determines where it lives, what it eats, etc. There are 1. 9 million described eukaryotic species on earth.
