8.2 A Local Ecosystem 1. The distribution‚ diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors Students Learn to: * Compare the abiotic characteristics of aquatic and terrestrial environments The impact of abiotic characteristics on environments Abiotic Characteristic | Differences | Similarities | | Aquatic | Terrestrial | | Temperature | * Small‚ gradual changes occur | * Large variations may occur | * Temperature

factors which may include natural selection and mating patterns. With the results from the Blanding’s Turtle experiment‚ who are listed as an endangered species‚ the topic of genetic diversity and genetic variation will further be discussed and researched. Genetic variation describes genetic differences among individuals of the same species. In a population‚ it is derived from a wide assortment of genes and alleles. This variation allows flexibility and survival of a population when the environment

a formal system of naming species of living things by giving each a name composed of two parts‚ both of which use Latin grammatical forms‚ although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial")‚ a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example

occurs between the individuals of the same species (T. Smith & R. Smith pg. 222). On the other hand‚ interspecific competition is the competition that occurs between the individuals of the different species (T. Smith & R. Smith‚ pg. 257). In this experiment‚ three basic experiments were conducted. The goal was to observe the effects of the competition in each instance. The first one was to observe the intraspecific competition between the mustard plant species. The second one was to observe the intraspecific

variety of genes in populations of single species‚ through species‚ on up to the array of natural ecosystems." This includes plants‚ animals‚ insects‚ fungi‚ bacteria‚ and all microorganisms. All of these things create what is known as a web. These things interact with each other in some way there for they depend on one another throughout their lifetime. There are many separate ways in which we can study biodiversity. These ways include‚ genetic‚ species‚ community‚ ecosystem‚ and taxonomic diversity

A trophic cascade is defined as ecological changes such as alterations in species abundance or composition‚ nutrient concentrations of plants‚ and the physical structure of the vegetation and environment. After wolves were eradicated from Yellow Stone National Park it caused a collapse in the tri-trophic cascade of predators‚ prey‚ and vegetation. They were reintroduced to restore the cascade that was present in the past to the park. The reintroduction of the wolves resulted in a major decline in

Co evolution is the evolution of two or more interdependent species‚ each adapting to changes in the other. It occurs‚ for example‚ between predators and prey and between insects and the flowers that they pollinate. (www.dictionary.com) This relationship between two species allows for their existence. They work together to ensure the survival of the other. The Bumble Bee Orchid (Ophrys bombyliflora) is a species of orchid that closely resemble a female bumble bee in both looks as well as smell

This short essay contains an outline of the pertinent points and concepts discussed by R. Buckminster Fuller in his essay Operating Manual for Spaceship Earth‚ which puts forward one argument for evolution. ‘Earth is only eight thousand miles in diameter‚ which is almost a negligible dimension in the great vastness of space. Our nearest star - the sun - is ninety-two million miles away. The nearest star’ after that ‘is one hundred thousand times further. It takes approximately four and one-third

Darwin’s theory of evolution can be broken down into two parts: the theory of microevolution and the theory of macroevolution. “Microevolution is the theory that natural selection can‚ overtime‚ take and organism and transform it into a more specialized species of that organism.” Macroevolution is the hypothesis that processes similar to those at work in microevolution can‚ over eons of time‚ transform an organism into a completely different kind of organism.” (Wile and Durnell 268). I am against the theory

Montana Paleontologists Compile Growth Series Analyses Adversely Affecting Dinosaur Species Diversity Holly Brown ABSTRACT The purpose of this paper is to report the findings of paleontologists Horner‚ Scanella‚ Goodwin and others regarding their study of growth series analysis in dinosaurs. They have provided evidence that what once was considered multiple different species of dinosaurs are actually varying stages of development in one genus. Utilizing the extensive fossil record at hand for
