5 Matching questions

  1. bioinformatics
  2. local extinction
  3. ecosystem approach
  4. wildlife
  5. population viability analysis (PVA)
  1. a Applied science of managing, analyzing, and communicating biological information.
  2. b Occurs when a species disappears from a part of its range but persists elsewhere.
  3. c Use of mathematical models to estimate a population's risk of extinction.
  4. d All free, undomesticated species. Sometimes the term is used to describe only free, undomesticated animal species.
  5. e Goal: to protect populations of species in their natural habitats.
    Strategy: preserve sufficient areas of habitats in different biomes and aquatic systems.
    Tactics: protecting habitat areas through private purchase or government action; eliminating or reducing populations of nonnative species from protected areas; managing protected areas to sustain native species; and restoring degraded ecosystems.

5 Multiple choice questions

  1. Mostly trees that can tolerate shade and form a fairly stable complex forest community.
  2. Species that is found in only one area. Such species are especially vulnerable to extinction.
  3. So few members remain that the species cannot maintain its ecological role, or members only survive in captivity.
  4. Manipulation of populations of wild species (especially game species) and their habitats for (1) human benefit, (2) the welfare of other species, and (3) the preservation of threatened and endangered wildlife species.
  5. Type of wild animal that people hunt or fish for, for sport and recreation and sometimes for food.

5 True/False questions

  1. minimum viable population (MVP)Minimum area of suitable habitat needed to maintain the minimum viable population. See minimum viable population.


  2. minimum dynamic area (MDA)Estimate of the smallest number of individuals necessary to ensure the survival of a population in a region for a specified time period, typically ranging from decades to 100 years.


  3. instrumental valueValue of an organism, species, ecosystem, or the earth's biodiversity based on its usefulness to us.


  4. threatened speciesWild species that is still abundant in its natural range but likely to become endangered because of a decline in numbers.


  5. wild speciesSpecies found in the natural environment.
