Extinction. \n  \n\nExtinction is a hot topic, of central interest to conservation, environmentalism and also to academic ecology. Ecologists are increasingly realizing that extinction has shaped the communities and ecosystems we see today, and that it operates on a range of timescales and spatial scales. \n\nExtinction doesn't just involve the complete loss of species, vanishing from the Earth. Extinction of local populations is often of key importance in shaping communities, even though other populations of the same species may exist in the same general area. \n  \n\nLocal extinction of populations. \n\nIn any area of forest, or patch of swamp, or coral reef, populations of animals and plants will be coming and going. If you were to compile lists of (say) all the bird species nesting in an fairly small isolated area of forest in Connecticut in one year then come back 20 years later, although most of the species in the list would be the same, the chances are that some of them would be absent (but quite likely replaced by other species). The ones that have come and gone would likely be the ones that had relatively few nesting pairs there anyway. \n\nWhy would they have gone extinct? Well, most often it would simply be that the population had a run of bad luck. Maybe there were 3 pairs nesting, and just by chance there for several years in a row there were late frosts that killed all the insects so the parents had nothing to feed their young, so the nestlings all died. Small populations are at the mercy of such 'bad luck', known as stochasticity. Even an initially abundant population (of say 150 nesting pairs) might still suffer a series of bad luck events (an exceptionally cold winter knocking back the population, followed by the late spring frosts) that can take it down from abundance to nothing at all in a few generations. \n\nAnother problem in a small population might be inbreeding. In species that normally have quite large populations and lots of exchange of genes, a range of harmful recessive genes can be present in the population without often showing themselves. Only when the population shrinks due to bad luck is there a significant chance of close relatives mating (e.g. if there are only 2 nesting pairs in the forest each year, the young are bound to end up mating with close relatives). When close relatives mate, they each have a good chance of carrying some recessive lethal genes in common; the result may be high mortality among the offspring. Experiments with repeated brother-sister crossings in domesticated animals (for several generations in a row) show that within 3 or 4 generations the young almost never survive to maturity because they have so many things wrong with them. This inbreeding effect is thought likely to hammer many isolated populations as their numbers get low, adding to the bad luck, although there are no well-documented cases of it occurring in wild populations. An apparent example of inbreeding effects appears to be the cheetah (see below), which has very low genetic variability apparently due to its numbers crashing to only 4 or 5 individuals at some unknown time in the last 10,000 years, then expanding rapidly again. Cheetahs have low fertility rates (e.g. very low viable sperm counts), and their cubs have high death rates that seem to be the result of its recent history of inbreeding. In this case, the population remained viable and recovered despite the inbreeding effects, but one can imagine that the problems might equally well kill off less lucky populations/species that reach very low numbers. \n\nObservations suggesting the importance of inbreeding in causing near-extinction:\n\n1) Gray Wolves of Isle Royale, Canada. The population was established by 1 breeding pair of wolves around 1949. By 1980 the population had grown to approximately 50 individuals, but by 1990 it had dropped to 14. Few pups were sighted by investigators who also noted that females were not breeding. Furth

Your best bet is to go to your teacher and schedule extra hours with them each day and study a lot. Keep doing the problems over and over until it becomes automatic. There are a lot of homework helpers out there if you do a little research you will find one. Your school can help you with this. Find a teacher to help you that you like and  you can relate to and learn from-that's important

I've found that the home is probably one of the worst places to do homework. Try staying later at school to study, or go to a library. This will minimize the numerous distractions like television.
