Biodiversity
Species that live only in a narrow range of biotic or abiotic conditions.
What are specialists?
A good produced by an ecosystem that humans can use directly.
What is a provision?
Describe the relationship between a natural disruption's spatial extent and its duration.
What is a positive linear relationship. Natural disruptions that last longer tend to affect a larger area.
Evolution at the population level.
What is microevolution?
Ecological succession occurring on surfaces with bare rock and no soil.
What is primary succession?
Species that can live in a wide range of biotic and abiotic conditions.
What are generalists?
Name the two physical characteristics of an island that affect the colonization rate of islands.
What are distance from mainland and size of island?
This kind of disruption occurs regularly, such as the daily cycles of day and night.
What is a periodic disruption?
Evolution that leads to new species.
What is macroevolution?
In primary succession, species that can survive with little or no soil.
What are pioneer species?
The number of species in a region or a particular ecosystem.
What is species diversity?
A description of how the number of species on an island increases with the area of the island.
What is the species-area curve?
The combination of abiotic conditions under which a species can survive, grow and reproduce.
What is fundamental niche? (Also known as ecological tolerance.)
A trait that improves an individual's fitness.
What is an adaptation?
A species that is not very abundant but has large effects on an ecological community.
What is a keystone species?
The relative proportion of individuals within the different species in a given area.
What is species evenness?
Specialists on islands are particularly vulnerable to these.
What are invasive species?
This Greek-derived word means "relating to or caused by humans".
What is anthropogenic?
The process in which the environment determines which individuals survive and reproduce.
What is evolution by natural selection?
A species that demonstrates a particular characteristic of an ecosystem.
What is an indicator species?
List the four scales of biodiversity?
What are genetic, species, habitat, ecosystem?
Plants removing half of the carbon dioxide that humans emit into the atmosphere every year is an example of this kind of ecological service.
What is a regulating service?
This satisfies the biotic AND abiotic conditions that a species needs to survive, grow and reproduce.
What is a species' realized niche?
An organism produced by copying genes from a species with some desirable trait and inserting them into other species of plants, animals, or microbes.
What is a genetically modified organism (GMO)?
What are species richness, total biomass, and productivity?
