Interpreting Plots
100
Density dependent population growth will lead to either a decrease in fecundity an increase in _______ or both
mortality
100
The process by which two species undergo reciprocal evolutionary change due to reciprocal natural selection for example a prey that becomes better at escaping will lead to predators that are better at stalking is known as?
coevolution
100
There are this many potential outcomes of competition between 2 species.
4
100
This is the term for the hunting strategy with a short search period, but a long and energetically costly chase.
pursuit
100
A clear sign of immune response from a parasitic infection and the first-line of defense from a host is _________
inflammation
100
This plot indicates that overall plant _______ increases with greater water holding capacity?
density
150
What is the term used when a tree extends its roots and utilizes soil water to the extent that there is not enough water for others to survive within their proximity?
exploitation
150
The total habitable space meeting a species needs is known as its
fundamental niche
150
This is the process by which competing species use the environment in different ways to coexist, reducing direct competition.
Niche partitioning
150
In addition to the lethal effects a predator population exerts on a prey population, non-lethal effects can also affect prey dynamics. A key example is the _________ response of Elks when there is a presence or absence of wolves.
behavioral
150
Disregarding its size classification, a tapeworm is an example of what kind of parasite?
endoparasite
150
Given the population birth and death rate plot, what is represented by the arrow and dashed lines when b=d?
K, carrying capacity
200
This form of competition occurs when growth and reproduction are depressed equally across individuals as competition intensity increases, a common example is planktonic species competing.
Scramble competition
200
This is a term used for when the effects of sharing space lead to partitioning of resources and divergence of traits reflected by phenotypic plasticity
adaptive radiation
200
The occupation of space by a barnacle precludes the establishment of another species, this is referred to as _______ ________
preemptive competition
200
The increase in predator reproduction rates in response to an increase in the consumption of prey is called the ________ _________
numerical response
200
This type of mutualist cannot survive without the interaction.
obligate
200
If the reproduction rate (r) of the prey is 10 and their capture rate is 2 (c), what would happen to the prey population if there are 6 predators?
Decrease
250
contrary to the availability of key resources, a stochastic event could be described as what relative to density?
independent
250
An epiphyte living on the bark of a tree can be described by what type of relationship?
commensalism
250
When a change in an abiotic factor like temperature allows creek chubs to drastically shoot up in population compared to trouts this highlights what well-demonstrated principle?
competitive exclusion principle
250
Some organisms living in the same habitat with inedible species evolve a coloration that resembles the warning coloration of the toxic species. This is referred to as _________ __________
Batesian mimicry
250
Plant parasites that are photosynthetic but draw water and nutrients from their hosts are known as
hemiparasites
250
Given your understanding of (a), the interaction between species 1 and 2 in plot b indicates that due to their mutual presence have adapted to their ________ ________.
realized niche
300
This is the term for the negative impact when population densities are too low
Alee effect
300
A fungi that naturally produces an antibiotic like penicillin in relation to the nearby bacterial colonies could be described as what kind of relationship?
amensalism
300
This is an interspecific competitive response characterized as a chemical interaction that limits growth or kills another organism in plants
allelopathy
300
Describes the similarity in color patterns among many unpalatable or venomous species.
Mullerian mimicry
300
This type of parasitic strategy is typically the case when a situation of originally commensal parasitism becomes mutualistic through an evolutionary shift
vertical transmission
300
What kind of functional response in gammarus is evidenced by this plot showing predation by sticklebacks on gammarus and artemia
Type 3
