may not be as glamorous as the megafauna of the Serengeti or the bird life of Borneo‚ but these “rocky intertidal” areas turn out to be great places to study community ecology. An ecological community is a group of species that live together and interact with each other. Some species eat others‚ some provide shelter for their neighbors‚ and some compete with each other for food and/or space. These relationships bind a community together and determine the local community structure: the composition

Why Zoos Are Necessary for the Cognitive Expansion of Humanity I. Introduction Since their inception in Ancient Egypt‚ (Rose‚ 2009) zoos have a place in our society‚ and always will. They are living museums of the saga of all natural life; bearing witness to a countless parade of evolutional history. The public has an unalienable right to experience these ecological wonders in a safe‚ welcoming environment. II. Argument A. Education of the Masses Zoos provide an invaluable service

While the name Aiptasia may mean “Beautiful”‚ Aiptasia pallida are an invasive sea anemone when it comes to saltwater fish tanks‚ but in the ocean‚ they are an important biological factor. Aiptasia come from the Class Anthozoa‚ and are commonly known as Glass‚ Rock‚ Tube‚ or Glass Rose anemones. They received their common name because they are semi-transparent (translucent) (Aiptasia Anemone). While much of this species of anemone are translucent‚ others are light brown or tan due to their symbiotic

They support life system of many species out of which 32% species population is occupied by the invertebrates alone (USDA‚ 2011). Invertebrates are the most versatile type of animal which can be found in almost all kinds of ecosystem and an astounding 90% of total animal species in the earth is occupied by them in terms of numbers (Kellert‚ 1993). The credit of their versatility can be given to the

members of Bryopsidales‚ Codium is siphonous and spreads quickly‚ often becoming a nuisance algae (Silva‚ 2008). There are many species within the genus Codium‚ but most of them are characterized by their spongy texture and the presence of utricles (Huisman et al. 2007). Species vary in color‚ sizes and shapes. They can be dark green to olive green in color. Different species vary in morphology‚ including‚ branched or unbranched‚ flattened‚ globose‚ terete‚ prostrate‚ or upright (Huisman et al. 2004)

Beetles have been around for over 270 million years and are one of the most diverse insects to roam the Earth and come in all shapes‚ sizes and colors. There are 350‚000 different species of beetles throughout the world and more yet to be discovered. They make up for twenty-five percent of all living things; There are so many of them because of their ability to adapt to any type of environment and live in almost every habitat except for polar regions or the ocean. Beetles are usually around habitats
