The rabbit bandicoot also known as the Biliby is endangered‚ and has been for eight years. It has been vulnerable to the environment for three years. They are endangered because feral cats and other larger animals hunt them. Also‚ there is competition between other animals for food. Another reason why they are endangered is because of land clearing and livestock grazing habits the grasslands are disappearing‚ which is where the Bilibies live. It is important to save these animals because they used

We hit the age where we can genetically alter foods with specific genetic engineering. Genetically altering certain foods sounds like a great idea‚ some companies modify their rice to contain a high amount of Vitamin A. That’s one example of the many genetically modified foods today. It seems like theres a high promise for genetically modifying crops to contain certain vitamins and to be able to withstand certain pesticides but there is the fear of the unknown. There are many reasons why people are

There is only one plant that the Callippe Silverspot will lay their eggs‚ and that is on a Jump-up‚ a relative of the violet. Once the larvae hatch in the early summer they begin to feed on the egg shell before going into a dormant stage of inactivity and low metabolism (U.C. Berkley‚ 1997). After winter is over the caterpillar emerge from their silk pad and feed on the now green Jump-up

A steep decline of predatory fish and a new oceanography that allows larvae to flow into their “nursery”. 9. There are signs that the numbers may be dropping. What are the plans to try and keep the industry booming? Maine will be putting in more rules and regulations on how many lobster traps each lobsterman can use and

The Organic Farmer A large section of the Kenyan population is unable to afford high protein food with adequate proteins‚ such as meat and eggs. This is where beans play a very important part; they are a cheap source of proteins. Unfortunately‚ the production of beans in most parts of the country is declining. The problem is the lack of good seeds

Ozone Depletion: An Introduction Planet Earth has its own natural sunscreen that shields us from the sun’s damaging ultraviolet radiation. It’s called the ozone layer: a fragile band of gases beginning 15 kilometres above our planet‚ and reaching up to the 40-kilometre level. Human activities have caused a substantial thinning of this protective covering — not only over the North and South Poles‚ but right over our heads. Stopping ozone layer depletion is one of the major challenges facing the

This is critical to the reproductive success of many amphibian and invertebrate species. Whom rely on habitats for breeding that are free of fish predators. Fish prey heavily on eggs and larvae and without seasonal pools most species would not be able to reproduce. Image on page 4‚ vernal pool in early spring.

CHAPTER 5. DISCUSSION 5.1. Water quality The average water temperature and average dissolved oxygen obtained during the experiment has been reported as the optimum range (3-10mg/l) for tilapia growth and yields (Meske‚ 1985). Siddiqui et al. (1989) stated that Oreochromis mossambicus has a low oxygen demand and can survive at low oxygen levels (1-2mg/l). Riche and Garling (2003) reported that dissolved oxygen levels should be maintained above 4.9 mg/l for best growth. The water quality tolerance
