Module 9: Biodiversity and Healthy Society Flashcards
The variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which include diversity within species, between species, and of ecosystems.
Biodiversity
Is a group of organisms that can breed and produce viable and fertile offspring. two animals are NOT the same species if they cannot mate, and produce a living, fertile baby.
Species
Are building block of earth that supports system. Without these, there is no human in a society.
Species
What are the three kinds of Biodiversity?
Genetic Diversity
Species Diversity
Ecosystem Diversity
Variations of all living forms at the genetic level: genes, alleles, or nucleic acids.
Genetic Diversity
It is the number of different species present in an ecosystem and relative abundance of each of those species. Diversity is greatest when all the species present are equally abundant in the area.
Species Diversity
Number of different species present in an ecosystem. Tropical areas have greater species richness as the environment is conducive for a large number of species.
Species Richness
Relative abundance of individuals of each of those species. if the number of individuals within a species is fairly constant across communities, it is said to have a high evenness and if the number of individuals varies from species, it is said to have low evenness. High evenness leads to greater specific diversity.
Species Evenness
The different habitats, biological communities, and ecological processes, as well as variation within individual ecosystems.
Ecosystem Diversity
Decrease of the population in size, usually due to adverse environment factors. During this, a population shrinks temporarily and therefore loses genetic variation. It also result from alterations in gene flow such as decreased migration, expansion into new habitats or population.
Bottlenecks
He is an American Biologist and the father of biodiversity.
Edward Osborne Wilson
Lost species may contain important scientific information or benefits to humankind, including “undeveloped medicines, crops, pharmaceuticals, timber fibers, pulp, soil-restoring vegetation, petroleum substitutes, and other products.
(The Diversity of Life, 2013)
HIPPO stands for what? (E.O. Wilson)
H = Habitat Loss
I = Invasive Species
P = Pollution
P = Human Population
O = Overharvesting
What year did Edward Osborne Wilson coined the acronym HIPPO to summarize those threats in order of descending importance?
2005
The areas that support natural ecosystems that are intact and where native species and communities associated with these ecosystems are well represented are called what?
Biodiversity hotspots
