Ecology lab report
An organism has several ways to avoid being prated upon. One way to avoid this is to practice crptis. Crypis is the action of organisms avoiding predation by blending in with their backgrounds and matching the color pattern of a bark, twigs or leaves. Palatable animals often utilize this strategy as well. Another type of defense is aposematism or warning coloratio. Organisms that produce noxious chemicals or accumalate them from food plants, advertise the fact that they are harmful with conspicous color patterns. Mimicry is the resemblence of an organism toward some other organism or an object inthe enviroment, evolved to decieve predators or prey into confuding the organism with that which it mimics. The prey involved within this experiment utilized mimisry as their defense stategy. Batesia mimicry, Mullerian mimicry, and aggressive mimicry are all various forms of mimicry. Batesian mimicry is a resemblance of an unpalatable species (model) by an edible species (mimic) to decieve predators. Mullerian minicry is a mutual resemblance of two or more conspicuousyly marked upalatable species to enhance predator avoidance. Aggressive mimicry is a tactic that enables predators to avoid being detected by their prey
For day one, the lime larvae was 66, while the observed removed was 0. 991 which is the chi analysis given in the book. The total # of prey removed for day 1 was 3. For day 8 of the lime larvae, deployed was 55, while the observed removed was 0. A refrigerator was utalized for the storage of prepared petri dishes with larvae. The red color had 100% mimicry, (palatable) and 0% for models (unpalatable). After graphing the data, I failed to accept my null hypothesis. For example blue unpalatable would be next to the lime palatable. Then we would add them up to get the chi analysis. Even the blue larvae was removed about as much as s the lime was another indication that mimicry had occured.
