Question

Two separate ponds were sampled for amphibian diversity Both ponds had the same number of specious was 1.3 for Pond 1 and 2.1 for Pond 2. What accounts for the difference in H' ? A. There is a mistake in the calculations for H' B. The Pond 2 is a larger pond and had more habitat C. Pond 1 was possibly dominated by one or two species D. Pond 2 had one species that was more abundant than the other species Which of the following would be considered an disturbance? A. variations in pH in an estuary B. hurricane C. seasonal temperature variations in the temperate zone D. disease What will happen to a population in a highly variable climate? A increase B. remain stable C. fluctuate (change a lot) D. decline Which of the following species is most vulnerable to extinction? ____ A. one with extensive geographic range, narrow habitat tolerance, and small local population B. one with restricted geographic range, narrow habitat tolerance, and small local population C. one with restricted geographic range, narrow habitat tolerance, and large local population D. one with extensive geographic range, narrow habitat tolerance, and large local population E. one with extensive geographic range, broad habitat tolerance, and large local population If the net reproduction rate of a population is greater than 1.0. what is the fate of this population? A. increase B. remain stable C. decline D. become highly dynamic Biotic factors that exert their influence on population density is called ____ factors. A. resource partitioning B. density dependent C. density independent D. competitive exclusion In fragmented patchy habitats, population abundance is determined by all of the following except: A. Sue of the habitat patch size B. How many habitat patches there are C. If the habitat patches are temporary D. Dispersal distance between habitat patches E. All are important It is difficult to show meta population dynamics in plants because A. Recolonization by dispersal is too infrequent B. Actual-extinction rarely occurs C. Recolonization facilitates germination of the seed bank D. The environment is too dynamic and the plant community is constantly changing In gap dynamics, the recolonization of the gap where all species have an equal ability to invade the gap and it is come first hold is called: A Competitive lottery A Subpopulation B Dominance controlled D. Community succession E. Synchronized succession A flood wiped out a section of the riparian habitat along the river. Ten years later, the plant community is diverse and has high structural complexity. The successional processes likely reflected in this community was A. Founder control B. Metapopulation control C. dominance control D. predator control Which of the following characteristics NOT describe a late succession species characteristic? A. Few seeds B. Large seeds C. Large dispersal distance D. Long viability E. High structural strength

Explanation / Answer

Abiotic disturbances – disturbances caused by non-living factors – are a natural and integral part of forest ecosystems that have major impacts, positive and negative.B: hurricane is abiotic
