Millipedes and Their Defense Mechanisms Abstract The class the millipedes are in‚ Diplopoda‚ is intriguing because it is thought to be one of the first animals to make the transition from water to land. Our lab group sought to find out under what circumstances and how millipedes use defense mechanisms. Do the millipedes curl up into a ball to evade predators? Do they bite predators and prey to inject a venom? Do they have a camouflage coating? These questions were answered by our lab experiment

increase causing there to be less plants in the area. Fewer resources could cause some organisms population‚ which depends on this source for food‚ to deplete. So if this keystone specie is lost‚ the whole ecosystem is affected. Not only is predation observed‚ but symbiotic relationships are also seen: mutualism‚ commensalism and parasitism. An example of mutualism would be the

proximity. This social behavior deviates from other cercopithecines (Kummer‚ 1968). A possible reason for this deviation is due to their predators. Males who condition females to stay close in proximity have a higher chance of protecting the female from predation. Consequently‚ their environment presents a high vulnerability rate from their predators because of the lack of tree coverage. Therefore‚ following the male leaders command increases the chances of survival. Furthermore‚ male leaders are the only

PREDATOR RELATIONSHIP OVER POPULATION DENSITY Study of species interaction has always interested ecologist. These studies help to develop the food web or chain where we see very simplified picture of interaction of species specifically about Prey and predation relationship .Prey predator relationship has been widely studied in ecology. An important general relation between prey and predator population was given by LOTKA-VOLERRA EQN. Which is a first-order non linear differential eqn given as: 1.dx/dt=x(A-By)

In the experiment‚ the selective pressure that affected the bivalves was the predation they faced from moon snails. The adaptive trait that was observed was the

Pythons do have predators. Younger snakes are more subject to predation from larger birds. Ball Pythons also can get eaten by wild dogs‚ hyenas‚ larger snakes‚ and some insects. This is a (+/-)
