Biodiversity
This type of biodiversity refers to the variety of genotypes available to a population
Genetic Biodiversity
This type of succession begins after an event that exposes bare soil to the surface, like a fire or heavy storm.
Secondary Succession
Resistance is the ability for a population to avoiding changing as a result of disturbances. This other word describes their ability to recover after a change.
What is Resilience?
One of methods that genes change within a population is with this event, in which a random mistake in the copying of genes can cause the appearance of new traits. Doesn't actually cause X-men.
Mutation
The limit of how many individuals in a population the environment can sustain. It's denoted by "K"
What is Carrying Capacity?
Some species, often called these, are vital to the health of the ecosystem, which would dissolve without them. They may help engineer the conditions of the ecosystem, like beavers, or function as limiter on herbivore species, like starfish.
Keystone Species
These two factors influence the number of different species that can be found on an island
Size and Distance from Mainland
The range of abiotic and biotic conditions under which a species actually lives.
What is Realized Niche?
In Darwin's original text on evolution, he describes this term as applying to individuals have the highest likelihood of surviving and reproducing.
Fitness
A resource that a population cannot live without and that occurs in quantities lower than the population would require to increase in size.
What is Limiting Resource?
Species Evenness
One service the ecosystem can provide is the harvesting of goods, called these. Some examples include lumber, honey, or medicinal ingredients.
Provisions
Based on our knowledge, earth has experienced 5 of these events in which many species die off in a short period of time. We are currently in the 6th.
What is Mass Extinction?
Physical separation of a group of individuals from others of the same species.
What is Geographic Isolation?
A factor that has the same effect on an individual's probability of survival and the amount of reproduction at any population size.
What is Density-Independent factor?
Before the later stages of succession can begin, the first plant life, often called these species, must settle in an area. They are usually things like mosses, lichens and algae.
Pioneer Species
Once succession concludes, the ecosystem is said to have reached this, which usually has lower biodiversity, biomass, and productivity than some of the earlier stages.
Climax Community
Some species function as an early indicator of change or ecological problems. Frogs, crustaceans, and some mammals are examples of this type of organism.
Indicator Species
Sometimes humans start to meddle in adaptations of species to benefit ourselves, like in dog breeding or agriculture. We call that this process, as opposed to the natural alternative.
Artificial Selection
The principle stating that 2 species competing for the same limiting resource cannot coexist.
What is Competitive Exclusion Principle?
Monarch Butterflies are this kind of species, as they only consume one type of food source, and rely on a specific path of migration to avoid cold temperatures.
Specialists
This type of ecological service usually applies to areas of religious or historical significance, exceptional beauty, or profound meaning to the local people
Cultural Services
This idea suggests that it is actually better for biodiversity for ecosystems to have some amount of disturbances. Not enough to prevent population growth, but also not so few as to allow some species to become hyper dominant.
Intermediate Disturbance Hypothesis
Major changes in the gene pool can occur when a large part of the population dies suddenly. Often called this effect, it can result in limited genetic diversity for the population going forward.
Bottleneck Effect
These are the 3 types of population distribution.
What are Random, Uniform, and Clumped?
