These fish closely relate to ecology and evolution. The researchers original findings are different than that of Robinson’s field study. His hypothesis states that the threespine sticklebacks varied phenotypes are the handiwork of natural selection supporting the discrepancy in the population. Diet and the

Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species
