what are some of the ecosystem services forest provide? - ANSWERSlocal climate, wild life habitat,
recreation, fuel, biogeochemical and hydrolic pump, steam function, water quality and streamflow, wood
& flow
how are coniferous and deciduous forests different? and explain the difference in leaf structure and
development of trunk and branches - ANSWERSconiferous= evergreen, needleleaf trees-reduces water
loss Branch structure maximizes light, Straight trunks, branch loss. Northern altitudes, boreal forest, taiga
Few species, spruce dominant
Cool, 50 cm rain annually
Moist soils, bogs common
Soils usually acidic, little other vegetation
Less dense, structural lumber (so\woods)
Deciduous= Broadleaf, nutrient resorption prior to prewinter leaf fall Curved trunks, permanent
branches
High transpiration potential
Four seasons, 75-150 cm rainfall
Rich soils from annual litter deposition
Widespread conversion to agriculture
Dense, high-quality wood (hardwoods)
what are the key factors that make primary and secondary succession different? - ANSWERS
What is the difference in the appearance of secondary & old growth forests and what are the key factors
that make them different? - ANSWERS
, What is the age maturity difference between angiosperms and gymnosperm? - ANSWERSgymnosperms
mature later meanig they have lower density (less of them) an ex would be walnut trees
list some soil characteristics. - ANSWERS
list some factors influencing forest development. Explain how/why they are important - ANSWERStemp,
rainfall, aspect, elevation, salinity, and shade tolerance.
explain the difference between shade tolerant and shade intolerant species - ANSWERSshade intolerant
species need sunlight during early growth and are usually Pioneer species, Inferior competitor for light,
Commercially important species. and shade tolerant species are able to flourish under a canopy, Often
dominant during late succession, Superior competitor for light, Commercially important species.
ex of shade tolerant and shade intolerant species - ANSWERSshade tolerant= magnolia, oaks, dogwood
shade intolerant=long leaf pine, douglas fir
what are some seeding and germination habits (bee video) - ANSWERSinsect, bird, and mammal
pollinators
- bird and small mammal seed dispersers
- indirect effects on forest production (co-evolution)
pattern and rate of growth of trees depends on ____ - ANSWERScompetition for light
- young trees grow fast to escape from herbivory
- recovery after disturbance
tell me a little about life history strategies of trees and fire, surface and crown, fire climax communities
and prescribed burning. - ANSWERSnegative forest impact or key role in forest ecology?
- thick, fire-resistant bark
- rapid regeneration after fire
- fire climax community
- part of tree life history
