... a herd every year, but the elephants continue to exist (Ward, 1997). It would have been harder though, for the mammoths and mastodons to survive a drought. Because of their size and weight, the Ice Age Proboscidea had longer gestation periods, which meant lower birth rates. If too much of the population was lost due to a severe drought, the population would be at ... of today. From this information, Haynes was able to deduce an assumption about reproductive patterns in the mastodon. The longer gestation periods in the prehistoric animals, because of their heavier weight, implies slower ...

Loss of habitat, climate change and UV radiation are just a few reasons for earths dramatic drop in amphibian's population in the recent years. Amphibians have lived on our earth longer then humans and adapt to a wide variety of habitats over the years. A recent study had proved that human neglect and ignorance has greatly impacted the amphibian population. In the remaining amphibian populations deformities such as extra eyes, or limbs have been reported in as many as 44 states. Some deformities are natural but in some areas up to 60% of amphibians have been reported ta have these defects. Our...
