Packet 5: Bonus 14
Hubbard Brook is an “experimental” one of these ecosystems in New Hampshire that functions as an outdoor laboratory for ecological studies. For 10 points each:
[10e] Name these ecosystems, whose “boreal” variety is characterized by dense canopy cover from conifers like pines and spruces.
ANSWER: forests [accept boreal forests; accept northern hardwood forests; accept experimental forests; accept Hubbard Brook Experimental Forest; reject “woodlands” or “jungles”]
[10m] This process studied at Hubbard Brook occurs when pioneer species colonize barren land. The “secondary” form of this process describes how species compositions change after a disturbance like a wildfire.
ANSWER: ecological succession [accept secondary succession; accept primary succession]
[10h] Researchers at Hubbard Brook measure the dimensions of plants to estimate this quantity, which equals net biomass accumulation plus organic matter losses due to mortality, herbivory, leaching, and volatilization.
ANSWER: net primary productivity [or net primary production or NPP; accept gross primary productivity or gross primary production or GPP; prompt on productivity or production; reject “secondary productivity” or “secondary production”]
