Question
Chapter 54.4, Problem 3CC
Summary Introduction
To analyze:
The comparison of species richness of birds on an island with snakes and lizards.
Introduction:
The island equilibrium model describes the immigration and extinction of species on an island. It shows the species' relation with the habitat and the equilibrium among them.

. Simulations 4-6 had lower density of birds (more spacing), how did this influence their ability to escape predation? With more spacing, which number of Junco’s was most advantageous (4, 8, and 16)? Ecologically explain this result.
If this flock of birds occurred in an area with low food availability what flock density would you predict? Explain how food availability impacts flock size/competition.
Was there a relationship between prop. Vigilance (proportion of birds looking up right before Hawk attack) and the rate at which they escaped predation?
Was there a relationship between Mean vigilance (average number of birds looking up each tick) and the rate at which the Junco’s the escaped predation? Was there a relationship between Mean vigilance and the number of birds in the flock?
Is this correct??? or is it the other way around
OBSERVATIONS
• Sea otters feed significantly on sea urchins, often keeping urchin abundance 'in check'.
• Sea urchins feed heavily on kelp, decimating kelp forests when urchin abundance is high.
• Kelp forests protect the shoreline from coastal erosion by buffering wave action.
• Orcas have been observed feeding on sea otters in the kelp forests of western Alaska.

- Think about a predator-prey system that perfectly follows Lotka-Volterra dynamics. The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle insteadarrow_forwardAn example of niche differentiation? *both forage in trees for insects and seeds *when sympatric, chestnut-backed tends to forage in higher branches than black-capped Chestnut-backed Chickadee Black-capped Chickadee ( - Black-capped (----) Chestnut - backed O Mike Hopiak 40 80 00 120 140 HEIGHT (feet) FiG. 1.

Kangaroo rats are endemic to the deserts of the American southwest. In one region, two kangaroo rat species eat only seeds and are biologically extremely similar.
