QuestionAnswer
A mass extinction of large mammals occurred during the ________ epoch.pleistocene epoch (The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago), and is ongoing.).
As latitude increases, the number of terrestrial species ________.decreases.
Total species diversity, or species richness, of individual communities is referred to as ________ diversity.local or alpha. (Beta - within a given region, variation in species diversity among communities. Ragional / gamma - total diversity/species richness across all communities within a geographic area).
Which taxa contain the largest number of known species?Coleoptera (biller).
When was the largest extinction in Earth's history?Permian
What is the evidence that exists to support the idea that the greater area of the tropics is the reason for higher diversity?The area between 0° and 10° is greater than between 60° and 70° latitude.
In relation to the stability hypothesis of diversity, which area provides the best evidence that glaciation reduced temperate tree diversity?Europe
What does this figure suggest?Mammalian diversity is highest at the equator
What is PET?potential evapotranspiration (potentiel fordampningstranspiration). An integrated measure of energy input to the ecosystem - species richness of terrestrial vertebrates is correlated with PET. (Actual evapotranspiration is an index that includes both the flux of thermal energy and water availability for evaporation(fordampning) - plant species richness is correlated with this).
Which of the following is strongly associated with net primary productivity? -actual evapotranspiration -ocean biodiversity -increased altitude -sea surface temperaturesactual evapotranspiration (an index that includes both the flux of thermal energy (strøm af termisk energi/varmeenergi) and water availability for evaporation(fordampning)).
As temperatures increase during seasonal fluctuations in marine environments,(what happens to species richness?)species richness decreases and species dominance increases.
Terrestrial vertebrate richness is most strongly tied topotential evapotranspiration (an integrated measure of energy input to the ecosystem).
Which of the following is increased amphibian diversity correlated with? -sea surface temperature -net primary productivity -altitude -distribution of land area across the globealtitude
A measure of diversity between sites (communities) is calledbeta diversity
Which state is most likely to be a hotspot for biodiversity?California
