As the area enters the hot millennium, mankind faces a sequence ofnew prob­ lems, lots of them created through guy himself. those comprise overpopulation, air and water pollutants, international warming, accumulation of greenhouse gases, darnage to the ozone layer and lack of biodiversity. might be those difficulties have been round even previous in an incipient degree, yet they've got now assumed international proportions and are uppermost within the minds of all. A traditional con­ series is improved curiosity in sciences attached with those difficulties. Ecology is a box that's immensely necessary in figuring out a lot of them. within the seventies, nature conservation turned a priority of vast sections of society, way past the small team of professional ecologists. Species extinc­ tion and depletion of organic assets have been visible as significant threats to human welfare. It was once consequently common for scientists from varied disci­ plines to hunt purposes at the back of those advancements. We have been no exceptions and while chance to engage with ecologists as statistreal experts got here, we discovered ourselves examining increasingly more of ecology and evolution­ ary biology. numerous years in the past we proposed beginning of an non-obligatory one semester path on statistical ecology for graduate scholars of data of Pune University.

Such models are called deterministic. In real life situations, more often than not, Nt is a random variable. The events associated with Nt viz. births, deaths , fertilization etc . have an inherent element of uncertainty. The statement that birth rate is A does not mean that every individual will produce A offspring in unit time. It just indicates the average number of offspring produced in unit time. The actual number is a random variable. Hence we model not Nt but p(Nt): the probability that population will be of size Nt at time t .

19) Clearly we expect to see oscillations in all these cases since we have a linear combination of two oscillating functions of t. If k is less than 1 these oscillations are damped but not otherwise. 7. THE ALLEE EFFECT So far we have tried to relax many assumptions involved in the c1assical logistic model. Inst ead of a linear per capita growth rate we considered a nonlinear one. In place of instantaneous response, we considered time delays . As alternative to continuous time we used discret e time etc.

Inst ead, it is possible that at very low dens ities say below a threshold L, difficulties other than resource limit ati on may arise. For example, individuals may find greater difficulty in locating mating par t ners. Or bir t h rates may get dep resse d and death rates increased because of inbreeding i. e. mating among closely related individuals. Eco logists call this 'A llee effect ' after t he scientist who discusse d it in a book in 1931. One way of incorporat ing such aspects into the model would be to intro duce an extra factor in per capita growth rate that causes its reduction when population falls be low the threshold L.
