Let's Get Specific
A species is defined as a population of organisms that can do these two things.
What are interbreed and produce viable offspring?
The combined genetic information of a population.
What is the gene pool?
Competition between different species.
What is interspecific competition?
A pattern of growth in a constant amount.
What is linear/arithmetic growth?
Populations will not increase indefinitely. This model of growth demonstrates that.
What is a logistic model/S Curve?
The Javan Rhino exists in a single national park in Indonesia, with an estimated 50 individuals remaining in the population. They are an example of this classification for species.
What is endangered?
The process by which one species develops into a new one.
What is speciation?
Competition among members of the same species.
What is intraspecific competition?
A pattern of growth at a constant rate.
What is exponential/geometric growth?
The number of offspring produced.
What is fertility?
Habitat loss, the introduction of invasive species, and pollution are all factors that can lead to this unfortunate end for a species.
What is extinction?
What is temporal isolation?
Two species competing for the same limited resource cannot both thrive.
What is the Principle of Competitive Exclusion?
The graph of population growth without any constraining factors.
What is a J Curve?
The ability to reproduce.
What is fecundity?
What is 5-30 million?
Populations have been separated by geographic barriers that prevent reproduction
What is geographic isolation?
When two species compete for a limited resources, one of these two results will occur.
What is extinction or adaptation?
The number of organisms that can be supported by an environment for a long period of time.
What is carrying capacity?
Humans demonstrate a Type 1 Survivorship Curve, have a long life history, and invest in their offspring. These are all example of this type of species.
What is a K-Strategist?
This landmark piece of legislation protects endangered species by placing trade restrictions and designating critical habitats as protecting.
What is the Endangered Species Act of 1973?
A catastrophic event severely reduces the number of individuals in a population, drastically reducing their genetic variation.
What is the Bottleneck Effect?
A small portion of an outcompeted population relocates in search of a better habitat. The genetic variation of the new population is much smaller than the parent population. This is an example of this effect.
What is the Founder Effect?
Temperature, storms, floods, and droughts are all examples of these.
What are density-independent factors?
A population pyramid of a country with a population in early decline will have this shape.
What is an onion?
