Quiz 1: Definitions and Important Info

Question 1

Xeric vs. Mesic vs. Hydric

Answer 1

• Xeric: dry environment/soil conditions w/ little moisture (drought tolerant plants)
• Mesic: moderate/well-balanced moisture conditions (supports wide variety of species)
• Hydric: Wet/saturated soil conditions where soil is waterlogged for part of growing season

Question 2

Define vertical structure

Answer 2

Layering of vegetation in a forest/plant community from the ground the the upper canopy

Question 3

What characteristics differentiate trees?

Answer 3

Leaf shape, compoundedness, serration, size
Bark patterns, depth, shape, thickness
Fruits, flowers, age, canopy

Question 4

What is bark plasticity?

Answer 4

Determined by biology w/ some flexibility through both biology (reproduction, hybridization, mutations) and environment (density of growing area, sunlight availability, temp. differences):
* environment can lead to darkening of bark color (white oak) or the lightening of it (black cherry)
* Biology sets in stone bark length, color, texture, and thickness

Question 11

Forest Cover

Answer 11

Question 12

Soil/land types for Forest growth

Answer 12

• Alluvial: loose sediment deposited by plowing water
• Palustrine: saturated/flooded for significant portion of growing season (ocean derived salts)
• Lacustrine: Standing water; sedimentary rock formations at bottom of ancient lakes
