biogeography

Question 1

what is biogeography

study of the ________ distribution of species

Answer 1

what is biogeography

study of the geographic distribution of species

Question 2

______, ______(______ stratification

), competition, and stability all contribute to the biodiversity present in a region

Answer 2

climate(whether more and moist, warm means longer days around, more photosynthesis), topography(Altitudinal stratification
), competition(drives formation of new species), and stability all contribute to the biodiversity present in a region

Question 3

Biodiversity hotspots are areas of conservation concern delineated based on biodiversity, ______, and ______

Answer 3

Biodiversity hotspots are areas of conservation concern delineated based on biodiversity, endemics, and threats

Question 4

species diversity is calculated based on ________ and ______. It is also important to consider species composition and taxonomic diversity when considering biodiversity

Answer 4

species diversity is calculated based on richness and evenness. It is also important to consider species composition and taxonomic diversity when considering biodiversity

Question 5

Current geographic species distributions may reflect historical continental configuration that has since changed due to _______ and/or past extinction events. Sometimes ______ evolution can result in similar looking species being geographically distant

Answer 5

Current geographic species distributions may reflect historical continental configuration that has since changed due to current/recent and/or past extinction events. Sometimes convergent evolution can result in similar looking species being geographically distant

Question 6

Species diversity: combines species richness and species evenness(Shannon Weiner Index)
Species _______: number of species in a region/community
Species ______: relative _______ of species in a region/community compared with one another (0 = no evenness, 1= complete evenness)
Species composition: identity of species in a region/community

Answer 6

Species diversity: combines species richness and species evenness(Shannon Weiner Index)
Species richness: number of species in a region/community
Species evenness: relative abundances of species in a region/community compared with one another (0 = no evenness, 1= complete evenness)
Species composition: identity of species in a region/community

Question 7

pattern of hotspot
near \_\_\_\_\_(more \_\_\_\_\_\_)
near \_\_\_\_\_\_\_ (tropics) 
islands(\_\_\_\_\_\_ species, due to isolation 
Coastal (\_\_\_\_\_\_\_)

Answer 7

near water(more isolation)
near equator (tropics)
islands(endemic species, due to isolation
Coastal (threatened)
