What is the species-area relationship in conservation biology?
Answer: Larger habitat areas support more species
The species-area relationship states that larger habitat areas typically contain more species than smaller areas of the same habitat type.
What is a wildlife corridor and what is its purpose?
Answer: A strip of habitat connecting isolated patches; allows animal movement and gene flow
Wildlife corridors are strips of habitat connecting fragmented patches, allowing animals to move, find mates, and maintain genetic diversity.
Which concept describes the minimum viable population (MVP) in conservation?
Answer: The smallest population size with a high probability of persisting long-term
MVP is the smallest population size estimated to have a reasonable chance of surviving genetic, demographic, and environmental stochasticity.
Which treaty regulates international trade in endangered species?
Answer: CITES
CITES (Convention on International Trade in Endangered Species) lists species and controls or bans international commercial trade in them.
What is bioremediation?
Answer: Using microorganisms to break down pollutants in contaminated environments
Bioremediation uses naturally occurring or engineered microorganisms to metabolize and neutralize environmental pollutants.
What is phytoremediation?
Answer: Using plants to absorb, contain, or detoxify soil pollutants
Phytoremediation uses hyperaccumulator plants to absorb heavy metals and other contaminants from soil and water.
