Species richness Study guides, Class notes & Summaries

Define biodiversity - ANSWER the diversity of plant and animal life in a particular habitat (or in the world as a whole) Define genetic diversity - ANSWER the total genetic information contained within all individuals of a species, population, or community Why is genetic diversity important? - ANSWER provides the raw materials for adaptive change Define adaptive change - ANSWER change in response to the environment's "natural selection: Define species diversity - ANSWER the diversi...

What is a population? - ANSWER interbreeding of a group of individuals who have the same species, geographics and time period. The population is exchanging genes What is the purpose of variability within a pop? - ANSWER some genetic variants have advantages and natural selection can act on variation Two process that can occur if a pop. cant exchange genes - ANSWER genetic divergence and speciation Decreasing variation in a species leads to- - ANSWER instability 3 levels of biodiversi...

population - ANSWER an interbreeding (sharing genetic information) group of individuals who live in the same geographic area and exist at the same time variability within a species/population (importance) - ANSWER important because: -some genetic variations have advantages over others -natural selection can act on the variation that arises What if populations are separated and can't exchange genes? - ANSWER two processes can occur: 1. genetic divergence 2. speciation genetic diverg...

What is FSC? What do they do? : Forest Stewardship Council Certifies forests, companies and products that meet sustainability standards Who is Thomas Lovejoy? : Founder of BDFFP (Biological Dynamics of Forest Fragments Project) He went to the Amazon Rainforest and purposefully created forest fragments What is BDFFP? : Biological Dynamics of Forest Fragments Project What is species richness? : the number of species in a community How does fragmentation affect species richness? 2 | P a ...

Genetic Diversity - correct answer measures variety of different versions of same genes within a species Species Diversity - correct answer measures number of different kinds of organisms within a community Ecological Diversity - correct answer measures richness and complexity of a community Fragmentation/Cloning - correct answer causes less genetic diversity within an ecosystem Species Richness - correct answer total number of species in a community Species Evenness - ...

Test 3 SCI 225What is an ecosystem? - correct answer a community of organism interacting with each other and their physical environment (biotic and abiotic) What is a community? - correct answer multiple species of organisms interacting with each other (biotic) what is a population? - correct answer one species What is species richness - correct answer the count, or total number of unique species within a given biological community, ecosystem, biome, or other defined area what is spe...

Define the term biodiversity - diversity of important ecological entities that span multiple spatial scales, from genes, to species to communities - biological diversity encompasses all species of plants, animals, and microorganisms, and the ecosystems and processes of which they are part Explain how the terms species, richness, evenness, and diversity are related Species richness: a count of all the different species in a prescribed area Species evenness: a measure of the rareness or c...

sci 225species richness - correct answer the total number of different species in a community species evenness - correct answer the relative abundance of species in a community (concentration of that species) which statement best describes biodiversity at the equator - correct answer species richness is higher at the equator than at the poles sedimentary rocks provide evidence of - correct answer long term (more than 1 million years) regional climate change a genetic mutation causes ...
