Geographic areas that have similar climates and ecosystems (classified by the types of life living there)
1 of 15
How is a Biogeographical Region classified?
Classified by why partcualr life lives there by accounting for anthropogenic, ecological and other biotic factors
2 of 15
How many Bio-Geo regions are there an which are part of the Holarctic?
There are 7 regions, two of which belong to the Holarctic, called Neoarctic and the Antarctic
3 of 15
What are the 5 regions that all belong to the Paleotropic relm?
Neotropical, Afrotropical, Australian, Palaearctic and Indomalayan
4 of 15
What continents do the Neotropical and Palaearcic regions cover?
Neotropical - South America. Palaerctic - Russia, north Africa and Europe
5 of 15
What are the charctersitics that differ between Savannas and Deserts? (How are they different)?
Both have high temperatures but Deserts have a dryer environment with poorer developed soils. And so Savannas have more vegetative growth than Deserts
6 of 15
What does Diurnal change mean? and what biome is this associated with?
Tropical Deserts - Is where there is large fluctuation between day and night
7 of 15
What biomes come under the Temperate biome relm?
Mediterranean Chaparral, temperature grasslands, evergreen forests and deciduous woodlands
8 of 15
What are the 3 main characteristics of the Mediterranean Chaparral?
There is high temperature all year with low rainfall and thus limiting the vegetation to mainly shrub-land
9 of 15
What characterises areas of being Grassland?
There must be less than 500mm of rainfall annually
10 of 15
How do evergreen forests and deciduous woodlands differ?
Evergeen forests are more simple with little ground cover of vegetation. Deciduous woodlands have more complex vegetation cover with high developed soils with also moist conditions
11 of 15
Which out of the 2 Polar/cold biomes has trees ?and what are the general characteristics of these 2 biomes?
Both biomes have low rainfall and low temperatures (Taiga has higher temperatures) with also only Taiga containing trees
12 of 15
How is the polar/cold Tundra able to have grass even though the temperatures are very low?
There must be 2 months of temperatures existing above 0 degrees during the summer so the soil has time to defrost to allow roots to grow
13 of 15
Why is the Arctic / Antarctic not really classified in a Biome?
Because there is no life (vegetation) there... Biomes are classified by the flaura and forna in that area
14 of 15
What is the link between Rainfall and the overall biota of an area?
High rainfall = more developed soils and so allowing large veetation and trees to grow as opposed to grass or shrubs and thus sustaining a large biodiversity and allowing a wider variety of organisms to occupy different niches
