These invaders arrived on ships from England, pumped out through the ballast. Zebra mussels are from a different environment (England), thus they are classified as an exotic species. These pesky animals thr

Pollution in our oceans is a serious problem. According to Marie Wild in her article “Ocean Pollution”, “Ocean pollution is one of the major killers of our sea animals.”. Most of the waste that is dumped is plastic, which takes hundreds of years to break down (Oceanic Research Foundation [ORF]). Everyday millions of animals are caught in fishing nets and six pack beer rings. It is thought that only fish are affected from getting caught in these. In reality they also kill birds

The Key Deer is a small species (in population and in stature) of deer that lives in the Florida Keys. It is in the same family as the Virginia white tailed deer.

They drop their antlers at the beginning of spring, and they grow back by June. The deer feed on indigenous plants including the red mangrove, the black mangrove, and the white mangrove. The K

Population estimation Introduction Estimates of population size play a vital role in many fisheries management decisions. The numbers of fish in a stock are used to identify influences of environmental factors, human exploitation, and ultimately to identify the effectiveness of management strategies. (Van Den Avyle & Hayward 1999) The three most common methods of population estimation among biologist are sample plots, mark and recapture, and removal. Counts on sample plots is based

Both bears can be perceived as large, clumsy and lumbering

Spiders This report deals with testing the toxicity of certain chemicals on spiders, and determining the toxicity by how it affects it’s ability to weave it’s web. This report contains research on the four chemicals (benzedrine, chloral hydrate, caffeine, and alcohol) as wellas the spiders and their webs. Spiders are of course found in the class Arachnidia, which also contain mites, scorpions, and other arthropods. The order which spiders are classified under is called Araneae

Introduction Malaria is one of the most prevalent and dangerous diseases known to man. It has existed for centuries and affects a myriad of people in the tropical region. Even today, with our newly discovered treatments for many of the tropical diseases, over 10% of the people that are infected with malaria each year and do not receive proper treatment die. In Africa alone, over 1 million children die each year because of malaria and new cases are reported frequently. Malaria is very

MANTODEA Most commonly known as the Praying Mantis, order mantodea is a group of about 1800 carnivorous insects which prodominatley live in tropical regions of the earth. Though certain species can be found in locations with moderate climate. With an extremely striking appearence, mantids almost have human like qualities with the ability to hold an erect stance, and arms that face forward.
