Forest Ecology Midterm Flashcards
Ecological equivalence
similar vegetation may occur on different sites: makes similar environmental factors, can predict with SMR, SNR, climate and ground surface materials
Coenocline
sequence of biotic communities along an environmental gradient (plant communities response to environment)
Site quaility
the sum total of all the many environmental factors affecting the biotic community
Commensalism
relationship between two different species in which only one benefits (epiphytic plants)
Ecotone
transitional areas between two adjacent biotic associations
fundamental niche
this is the maximum niche a species can occupy in the absence of competition from other species
realized niche
a portion of the fundamnetal niche occipied with a species within the presence of competition
Ecosystem classification
organizes ecosystems according to their similarities(structure/composition/vegeation/site attritbutes
Habitiat
type of range of environments in which a species lives
Radiation frost
occurs when the ground surface cools below 0 C through the net loss of long wave radiation to the atmosphere
advection frost
occurs when air, which radiatively cooled to below freezing at another location, flows onto a site (also referred to as cold air ponding or pooling)
Site factors that affect precipitation
geo location
elevation
topography
In terms of SMR and SNR what does Oplopanax, Calamagrostis and Blechnum
Skunk Cabbage SMR 6(very wet) SNR 3(rich) Pinegrass SMR 2 SNR 2 Deer Fern SMR 4 SNR 1
Draw solar radiation changes with slope percent and aspect
draw
burning/tropical shifting, sustainable?
removing fire has effects that change the environment
