You hypothesize that prey choice and gender of the predator are not independent of each other when it comes to hawk feeding beheavior. Using the table of data below, determine if the data supports independence of those two categorical variable.

  Squirrel prey    Pigeon prey

Male hawk    64 42

Female hawk    37    46

What is your null and alternate hypothesis?  Calculate if the factors are independent of each other.  Clearly indicate why you reject, or fail to reject, your null hypothesis, and why

Predator-Prey You are a scientist that studies raccoon behavior and diet. Although raccoons are carnivores, they have a very diverse and opportunistic diet. As part of your research you are collecting scats (raccoon poop) from rural areas in the Shawnee National Forest, as well as urban areas (neighborhoods of Carbondale and Marion, Illinois). Explain in detail how you will use the raccoon scats to identify diet items of raccoons (include some of the techniques you will use). Do you expect...

Studies of mimicry in predator-prey systems often use plastic/clay replicas of prey species to determine if predators preferentially avoid the mimic and model, just the model, just the mimic, or even additional species not thought to be the model or the mimic. Replicas are placed for days to weeks in habitats thought to contain predators, models, and mimic, and researchers then count the number of “wounds” or missing replicas as an indication of whether models and mimics are equally avoided/attacked....

1. How does distance of a prey item affect the net energy gain of the predator? 2. How does prey size affect the optimal distance at which to pursue prey? 3. How does abundance of prey affect the optimal distance? 4. What is the relationship between net energy gain and distance to the prey item for small prey?

Please USE C++ The goal for this Project is to create a simple two-dimensional predator-prey simulation. In this simulation the prey are ants and the pred-ators are doodlebugs. These critters live in a world composed of a 20 × 20 grid of cells. Only one critter may occupy a cell at a time. The grid is enclosed, so a critter is not allowed to move off the edges of the world. Time is simulated in time steps. Each critter performs...

The predator-prey relationship between gray wolves and moose on Isle Royal in Lake Michigan has been studied for decades. Although both populations fluctuate, the moose have never been driven to extinction. In this case, as well as many others, wildlife ecologists and managers often refer to the victims of predation as a “doomed surplus.” Use the concepts of reproductive value and survivorship to discuss what this means.

Hypothesize how your two buffers’ pHs will compare to each other. (Will one be higher than the other? If so, which one?) Explain.  One solution will need 28-32 mL of NaH2PO4 and 18-22 mL Na2HPO4.  The other will need 18-22 mL of NaH2PO4 and 28-32 mL Na2HPO4. Assume you make a buffer with 20 mL KH2PO4 and 30 mL K2HPO4. Both solutions are provided at a concentration of 0.2000 M and are made to a final volume of...
