Biodiversity
The four types of biodiversity.
What are species diversity, genetic diversity, ecosystem diversity, and functional diversity?
The role the species plays in an ecosystem and everything that affects its survival and reproduction.
What is a niche?
The mechanism for evolution.
What is natural selection?
The normal, gradual change in species composition in a given geographic area.
What is ecological succession?
The maximum population of a given species that a habitat can sustain indefinitely.
What is carrying capacity?
What is between 2-29%?
A species that eats a wide variety of foods and can live in a wide range of environments.
What is a generalist species?
The mechanism for evolution within a population.
What is gene mutation?
The timeframe for primary succession to occur.
What is hundreds to thousands of years?
The type of factor that becomes more important as population size increases.
What is a density-dependent factor?
The variety of processes that occur within ecosystems, such as energy flow and matter cycling.
What is functional diversity?
A species that affects the types and abundance of other species in an ecosystem.
What is a keystone species?
Any heritable trait that gives individuals some advantage over others in a population.
What is an adaptation?
What is by increasing species diversity and interaction among species?
The type of curve that represents exponential growth.
What is the J-curve?
The idea that biodiversity correlates with an ecosystem's ability to resist decline in their functioning when changes in the environment occur.
What is the insurance hypothesis?
When two species interact over a long period of time resulting in changes in the gene pool of one species causing changes in the gene pool of the other.
What is coevolution?
The limiting factors for natural selection.
What are that the genetic traits must already be present in a population's gene pool and that the ability to adapt may be limited by reproductive capacity?
The mechanism by which secondary succession enhances sustainability.
What is by promoting population control, which in turn increases the complexity of food webs, enhances energy flow, and increases nutrient cycling?
Reproductive strategy where the species are opportunists that can reproduce rapidly under favorable environmental condition.
What is an r-selected species?
The mechanism by which biodiversity is beneficial to humans.
What is by increasing natural capital?
The type of interaction that best describes a barnacle being attached to the side of a whale.
What is commensalism because the barnacle benefits by having a place to live and access to food while the whale is largely unaffected?
The ability of one or more organisms in a population to tolerate chemicals designed to kill the population.
What is genetic resistance?
The difference between inertia and resilience.
What is that inertia is the ability of an ecosystem to survive moderate disturbance and resilience is the ability of an ecosystem to be restored via secondary succession after a severe disturbance?
The survivorship curve for a species where few individuals die in early and middle life and most die at an old age.
What is a late loss survivorship curve?
