Ch.4 Reading (Week 1) Flashcards
what effects broad and local vegetation type (5)?
precipitation, temp (broad), soil, landform, and history (local)
Trees use a great deal of water when….
precipitation is too low
North America is controlled less by total yearly participation and more by…
seasonal distribution
How much does the temperature differ in tropical forest?
no more than 5 degrees C
What are two key characterizations of temperate forest?
-distinct winter
-precipitation concentrated in the winter and long growing seasons
Boreal forest are home to… type of trees
hardwoods (birch, aspen, alder)
What type of winters and summers do Boreal forest have?
temps falling below -40 degreesC (winter)
short, moist, and warm summers
Deep supercooling
in plant tissues prevents intracellular freezing while limiting the degree of cellular dehydration
Forest on high mountains are called
Montane
Hopkins Bio geoclimatic Law
temp change over 1000 m in elevation is similar to that occurring of 5 degrees of latitude.
How do trees in tropical forest do when drought last long
shed leaves
What are the four types of tropical forest
evergreen tropical rainforest, seasonal rain forest, tropical semievergreen forest, and deciduous tropical forest
Types of temperate forest…. (4)
moist conifer forest and evergreen broad leaved forest (rainfall concentrated in winter)
dry conifer forest, temperate broad leaved rainforest
Mediterranean
Climate where precipation is concentrated in the winter and precipitation is around 1000mm/yr
sclerophyllous
leaves of broad leaved trees
What type of tree has a higher productivity than many tropical forest
Redwoods
the three patterns of particular relevance to ecology and forestry are…
species diversity, distribution and cycling of essential elements, and productivity
Where is there a higher concentration of mosquitos , lizards and amphibians but fungi do not follow this trend?
The equator
- diversity of plant and animals species drop sharply as one moves from tropics to higher latitudes
Rapid decomposition in tropical forest is matches by…
rapid nutrient uptake
What happens if migration of trees does does keep up with climate change
it leaves space for weedy species eventually declining and deaths of forest
Holdridge Life Zone Classification
used to see how relating vegetation types to avg. annual temp and precipitation. (climate change)
Model is not perfect
Forest that support more leaves than do other vegetation types require more…
water
