There is a constant threat of animals being shortlisted onto endangered Specie lists. It appears we will only be able to deal with a fraction of those on the endangered list because of the large costs in keeping the population as it once was. The same can be said for plants whose native habitat is being destroyed systematically.

Plants are the major source of the foods that we consume every day. Plants are the major source of many products that we use.

Further study on the interactive behavior between predator and prey or between competing predators have shown that previous information is incomplete or erroneous. Relationships between large predators are complicated involving territorial recognition and lately crowding has probably increased the incidents regarding potential conflicts.Animals that were once considered lesser hunters have been found to outwit their larger competing animals.

Outlines of the major differences of the process of RNA Transcription in Prokaryotes and Eukaryotes. Major transcription stages are listen and described in detail the specific differences. The stages are Initiation of DNA transcription to RNA, elongation of the RNA strand and termination of transcription that indicates the next step of translation.

The mollusk biomphalaria glabrata is a freshwater snail that has a protective shell. The biomaterial shell is composed of calcium carbonate and some matrix proteins. Because the freshwater can reproduce asexually or sexually, the snail can choose to mate or not. It can be found in lakes, swamps, and streams in South America. With only 18 chromosomes, it is consider to have a simple genome.

Humpback whales migrate north from Antarctic to warmer northern Pacific feeding and breeding grounds during the winter months of June and July. They pass through the waters of Cook Strait, New Zealand, where an annual survey monitors population numbers, establishing the rate of recovery of these mammals since commercial whaling was banned in New Zealand in 1964. The 2012 survey began on Saturday 9 June.

With animals becoming endangered and extinct at an alarmingly rapid rate due to human encroachment, environmental issues and other factors it is so important that we become familiar with the animals that share this planet with us. Too often we humans have taken the Earth for granted and naively ignored the impact we have environmentally.

There are so many amazing and truly strange creatures that we never really know about, much less learn about. It's fun to find out new information about an animal that you never really knew existed before. In the ever pressing demand to save more animal species knowledge is the best weapon against extinction.

In northern California oak woodlands cover nearly 4.5 million acres of typically rolling terrain that is bounded by valley grassland, chaparall, and montane forest (Holmes, 1990). Oaks are mostly found at high elevations under cool or temperate climate. The oak communities in California include blue oak (Quercus douglasii), blue oak-foothill pine (Pinus sabiniana), coast live oak (Quercus agrifolia), and valley oak (Quercus lobata) (Purcell, 2006). Throughout their evolution oak trees acquir...

It is not an airplane, it is not superman, it is not a space shuttle. It is the Bar-Tailed Godwit. The Bar-Tailed Godwit can fly for 8 days non-stop. Scientists tagged this bird and found out that it is the record holder for long distance flight. The Bar-Tail makes the world's longest trip in air without stopping for food or water. This bird traveled from Alaska to New Zealand (7,258 mi) without getting any sleep and it does not need a co-pilot.Consider this, the Bar-Tail travels farther than an...
