1. Population genetics- Population Genetics is the study of the distributions and changes of allele frequency in a population. As demonstrated with the popgen fishbowl  stimulation, the population is subject to the four main evolutionary processes also known as natural selection, genetic drift, mutation flow, and gene flow.

• 2. Population Ecology- The Logistic Growth model demonstrates resource limited population growth. Populations have a per capita growth rate and carrying capacity and individuals in a population are views in windows, which show that there are still births/deaths in the population.  Population sizes can be predicted through direct sampling, sampling with removal, and mark/recapture. 
• 3.Community Ecology: A model of Connell's 1960 competition experiment if of realized niches of two species of barnacles, Chthamalus and Balanus. In addition, microcosm is a simulation which demonstrates Gauss (1934) experiment with protists. The two Paramecium species compete for resources. 
• 4. Behavioral Ecology: In Foraging, the model demonstrates a behavior of honeybees.  It represents  Charnov's (1976) Marginal Value Theorem, which predicts how long an animal should forage in a given patch. In Vigilance Behavior (Collective),  the model is shown of Pulliam's (1973) vigilance model  suggests that an advantage to birds of feeding in flocks is that there are multiple eyes eyes watching for predators. In Vigilance Behavior   (Individual) the parameters for individual birds can be adjusted.  In Foraging, the model simulates the foraging behavior of two predator species and tracks the mean and standard deviation in energy for each species. 
• 5. Conservation Ecology: In biomagnificaion, Rachel Carson published 'Silent Spring' which drew attention to how the use of pesticides was indirectly decimating bird populations by causing thinning of egg-shells in 1962. The model demonstrates how DDT in near-shore waters accumulates in a 'food chain' of phytoplankton, zooplankton, smelt, salmon, and pelicans. In Tragedy of the Commons  Garrett Hardin (1968) describs how multiple individuals acting in their own interests, while using a common resource, will overuse the resource.   This model shows the concept in a common field where four farmers are grazing cattle.  
•  6. Biodiversity: In island Biogeography, a model MacArthur & Wilson's 1963 Island Biogeography Equilibrium  paper is demonstrated. In estimating stream diversity, the model shows a stream of animal life and displays the species"disocvery to effort" to curve. In estimating plant diversity, it is a model to clacuate data for anlayses of biodiversity.

Evolutionary Creature in the Ice Age

I created a creature called the Bunnusoaious that lives in both the land and the sea during the Ice Age. This creature evolved because brown rabbits were getting rapidly eaten by the polar bears because they were the only prey left after its other prey got extinct because of the ice age. It has a fin which helps it navigate its way through the ocean when escaping from predators on land. This creature spends most of its time on land which is indicated from its bunny legs as it hops around on land to find food. It has two sharp and long teeth to help it hunt for food in the water (fish) and on land (small mice found in the snow). It two long ears to help it hear when its prey and predators are nearby. It has fur on its fish-like body to help it survive the cold. It is also the color white on the top to help it blend into the surroundings so to not be hunted easily and is able to live in a habitat in the snow. However, it also has blue on its belly to camouflage into the water to escape its predators under water and white fur to escape its predators on land. It also has gills to help it breath in the water when it goes into the icy, cold ocean.

Evolutionary Bird

This bird is called the Tribirbeakasours. It has two long wings that help it glide through the sky because it lives high in the mountains, its natural habitat. It has two pairs of legs, the one with big nails and fingers to grab its prey when its swoops down underneath to catch its prey, and the little birds one to sit in it cave in the mountains. The bird has two different hunting beaks in addition to help support to catch its prey. This bird lives in the sky and deep into the heart of the mountain. It is red and gray to help blend into the mountain and and has a feather on the top of its head to mate with other birds of its kind.

Fake Fossil Blog

The fossil I found was 3.2 centimeters wide and 2.8 centimeters in length. It had ridges and some damage had been done to the fossil. The fossil had an oval shape that was not perfect. It was buried 4. 3 centimeters deep and had a shallow hole. It was clear that the fossil had been buried in the  recent years because the fossil was in good condition. The fossil was also buried in the ocean as could tell because it was within a hole. Overall, my conclusion is that this fossil is a shell.

My partner and I were the spooned beak birds. I struggled to survive the first round and sadly died because I could not adapt, while Shirley barely survived. In round 3 I went to different island in order to obtain more food. I tried to scooping the m and m together but not seem to find a solution to fix the problem.  I was better adapted to the bigger seeds as Shirley and I appeared to struggle on the first island. I would identify myself and Shirley would be the vegetarian finches because  we struggled on both islands, only one of us surviving to barely survive. I struggled very much to work together with Shirley because I thought it would be better to hunt on my own for food. Overall, I was better adapted to the small sized seeds I faced Intraspecific competion, as I struggled to fight Rui who was a forked beak to get small seeds.

The paleolithic

Your first blog is a possible history of your geologic area Include
density of fossils and why they are in one area and not another
density of fossils 2 where are there the most samples why
type of fossils and what that says about the area

The density of fossils for the Paleolithic Era was on the right side of the shoe box. This may have possibly been because there was land on the left side and ocean on the right side. One shark tooth which was found in H1 indicates that ocean life existed on the right side and 2F which is petrified wood indicates that  it was a lake that had trees right new to it.  Almost little to no animals life was on land as there was only one dinosaur bone found. However, there was much plant life on land and in the ocean as can tell by the 5 fossils found of corals and wood.
