What is Biodiversity?
The variety of life in an ecosystem, including diversity within and between species.
What is Genetic Diversity?
The variations within a species, providing the raw material for adaptation and survival.
What is Species Diversity?
The variety of different species in an ecosystem.
What is a Keystone Species?
A species that has a disproportionately large effect on its ecosystem relative to its abundance.
What is Ecosystem Resistance?
A measure of how much a disturbance affects an ecosystem's functioning; high resistance means less affected by changes.
What is Ecosystem Resilience?
A measure of how quickly an ecosystem recovers after a disturbance; high resilience means faster recovery.
What are the key differences between Ecosystem Resistance and Ecosystem Resilience?
Resistance: Ability to withstand disturbance | Resilience: Ability to recover from disturbance.
What are the differences between a Keystone Species and a Dominant Species?
Keystone Species: Disproportionate impact | Dominant Species: Most abundant.
What is the effect of low genetic diversity in a population?
Increased vulnerability to extinction due to reduced adaptability to environmental changes and diseases.
What is the effect of removing a keystone species from an ecosystem?
Catastrophic ecosystem effects, potentially leading to collapse due to the disruption of essential ecosystem services and food web dynamics.
What is the effect of increased biodiversity on ecosystem resistance and resilience?
Increased resistance and resilience, enabling the ecosystem to better withstand and recover from disturbances.
What is the effect of a pathogen outbreak on a population with high genetic diversity?
The population is more likely to survive because some individuals may have natural immunity.
