In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction

University of Florida campus in Gainesville‚ FL. Spanish moss is an atmospheric epiphyte and the Southern live oak is a hardwood tree. Some possible interactions between the two species were neutralism‚ commensalisms‚ mutualism‚ and parasitism. It was hypothesized that the relationship would be commensalism‚ with Spanish moss benefited and the Southern live oak neither benefited nor harmed. The type of symbiotic relationship was determined using two factors‚ the relative health of the host oak tree and

ecological community consists of all the interactive species living within a certain area or a certain habitat. Most species have interacted over a long period of time. The interactions fall into categories including commensalism‚ competition‚ parasitism‚ predation‚ and mutualism. Commensalism is when one species will

Essay Of the Differences Between Desert And Coral Reef Coral reef and Desert ecosystem. The coral reef and desert ecosystem can be very similar or very different.The difference between the biotic and abiotic factors in the coral reef and the desert the ones in the coral reef live under water ‚and in the desert none of them live under water only some of the fish do. Some of the biotic animals in the coral reef are dolphins and seals. bivalves‚ gastropods‚ tunicates‚ sponges‚ polychaete and feather

Species Interaction * The relationships between two species in an ecosystem. * The interactions between two species need not be through direct contact. Species may affect each other through intermediaries such as shared resources or common enemies. Major factors in evolution and adaptation: * Predation * Competition for scarce resources Terminologies: * Habitat – the actual physical location where a species lives. * Conditions – physical or chemical attributes of the

If you are not sure of what the concept is or means search for the answer in your textbook and write it on a separate sheet of paper. If you know these terms you should do well on the test. Chapter 52 – Ecology and the Biosphere 1. Distinguish among the following types of ecology: organismal‚ population‚ community‚ ecosystem‚ and landscape. 2. Explain how dispersal may contribute to a species’ distribution.
