All Flashcards
What are the effects of a population bottleneck?
Reduced genetic diversity, increased vulnerability to extinction.
How does clearing a forest impact biodiversity?
Reduces genetic, species, and habitat diversity, disrupting ecosystem processes.
What is the effect of low ecosystem resistance?
The ecosystem is severely impacted by a disturbance.
What is the effect of low ecosystem resilience?
The ecosystem takes a long time to recover from a disturbance, or may not recover at all.
Define biodiversity.
The variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it.
What is genetic diversity?
The variety of genes within a single species.
Define species diversity.
The variety of different species within an ecosystem.
What is habitat diversity?
The variety of different habitats in a given area.
Define population bottleneck.
A sharp reduction in the size of a population due to environmental events or human activities, which reduces genetic diversity.
What is species richness?
The number of different species present in an ecosystem.
What is species evenness?
How evenly distributed the populations of each species are in an ecosystem.
Define ecosystem resistance.
The ability of an ecosystem to withstand or resist changes caused by disturbances.
What is ecosystem resilience?
The ability of an ecosystem to recover quickly after a disturbance.
Define Simpson's Diversity Index.
A quantitative measure that estimates the species diversity of a community. A higher value indicates greater diversity.
Define biodiversity.
Variety of life on Earth, including plants, animals, and microorganisms.
What is genetic diversity?
Variety of genes within a single species.
Define species diversity.
Variety of different species in an ecosystem.
What is habitat diversity?
Variety of different habitats in a given area.
Define population bottleneck.
Dramatic reduction in population size, leading to loss of genetic diversity.
What is species richness?
The number of different species present in an ecosystem.
Define species evenness.
How evenly distributed the populations of each species are in an ecosystem.
What is ecosystem resistance?
How much an ecosystem is affected by a disturbance.
Define ecosystem resilience.
How quickly an ecosystem recovers after a disturbance.
