What is interspecific competition?
when two or more species are competing for the same resource
100
In the magnitude of interspecific competition equation, ahat does Byx stand for?
The biomass of plant y when grown with plant x
100
In the allocation of biomass equation, what does Bpart stand for?
biomass of the plant part of interest
100
What is the equation for logistic population growth?
dN/dT=rmaxN(k-N/k)
100
in the determining population size equation, what does x represent?
the number of individuals tagged at a later observation
200
For magnitude of interspecific competition, the ________ the number, the greater the effect that one species has on the growth of the other species
greater
200
The allocation of biomass to different parts of a plant's anatomy can change with different...?
environmental stresses
200
Bio mass is the ______ per capita ______
average, weight
200
What is an equation used for determining population size?
N=sn/x
200
What is the mark recapture method?
a sample of individuals in a population are identified or tagged so that they can be easily identified the next time they are seen
300

Cyx=(By-Byx)/By
300
What is the allocation of biomass equation?
Ppart=Bpart/Btotal

In the population size equation, what does N stand for?
estimated size of population
300
What is the way the textbook shows how to calculate estimated population using mark recapture?
(number of marked individuals observed in second sample, x)/(total number of individuals in second sample n) = (number of individuals originally marked s)/(estimated number of individuals in population N)
400
In the magnitude of interspecific competition formula, what does the Cyx stand for?
effect plant x has on plant y
400
In the allocation of biomass equation, what does Ppart stand for?
proportion of biomass allocated to the plant part of interest
400
Allocation of biomass is a response to what common type of stress?
competition
400
in the determining population size equation, what does s stand for?
number of animals tagged
400
What are assumptions made when using the mark recapture method?
no migration, all individuals have equal chance of being captured and recaptured, mark or tag doesn't affect the likelihood than an individual will be recaptured, and that marked individuals do not lose their tags before recapture takes place
500
