Biologist Frank Oliver described the broken up old growth forests by saying, “There are more ___ in the blanket than there is blanket.”
What are holes
In a prairie biome, the alpha richness (# of species in local area) is 4 and the gamma richness (total # of species in a larger region) is 10, what is the beta richness?
What is 2.5
Allopatric speciation is when a single population is split by what?
What is geographic location
Introduced from southeast Asia, this fungal pathogen is believed to have driven at least 30 amphibian species in Panama extinct since 1998.
What is chytrid
What extinct bird was native to Mauritius?
What is the Dodo Bird
Even where the timber industry has replanted, these broken topped dead trees, favored by the owl, osprey, and pileated woodpecker, are gone.
What are snags?
Name 2 of the 4 environmental gradients causing geographical differences in species diversity.
What is Productivity, Latitude, Elevation, Complexity
What is the difference between microevolution and macroevolution?
What is:
Micro is change of traits from one generation to the next, macro is the creation of species from a common ancestor over many generations
Globalization moving pathogens into host populations that have never been exposed to the pathogen before is described by this word
What is naïve
Name 3 categories of the IUCN Red List.
What is Least concern, Near Threatened, Vulnerable, Endangered, Critically endangered, Extinct in the wild, or Extinct
Oliver and other biologists observed that it is not the age of a forest that seems critical to owl habitat, but rather these two qualities of the forest.
What are its structure and character
Name one benefit and one criticism of the biodiversity hotspot approach.
Benefit example: High proportion of species diversity done relatively cheap by targeting a few areas with high diversity
Criticism example: doesn’t necessarily conserve the full range of species, doesn’t consider genetic diversity, doesn’t consider difference in cost of land, doesn’t consider ecosystem process and services
If you have a normal or background rate of speciation, and an elevated rate of extinction, what will happen to the species diversity?
What is it will go down
The fungus behind white nose syndrome persists in caves even after the bats are gone, making it an example of which of the three reasons behind disease induced extinctions.
