Intraspecific Population Regulation

100

Density dependent population growth will lead to either a decrease in fecundity an increase in _______ or both

mortality 

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

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

250

contrary to the availability of key resources, a stochastic event could be described as what relative to density? 

independent

300

This is the term for the negative impact when population densities are too low 

Alee effect

Species Interactions

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 

150

The total habitable space meeting a species needs is known as its

fundamental niche

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

250

An epiphyte living on the bark of a tree can be described by what type of relationship?

commensalism

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

Interspecific Competition

100

There are this many potential outcomes of competition between 2 species.

4

150

This is the process by which competing species use the environment in different ways to coexist, reducing direct competition.

Niche partitioning

200

The occupation of space by a barnacle precludes the establishment of another species, this is referred to as _______ ________

preemptive competition

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

300

This is an interspecific competitive response characterized as a chemical interaction that limits growth or kills another organism in plants

allelopathy

Predation

100

This is the term for the hunting strategy with a short search period, but a long and energetically costly chase.

pursuit

150

This functional response occurs when the rate at which prey are consumed is low at first, increasing in a sigmoid fashion as the rate of predation approaches the maximum value, often due to prey behavior like escape or hiding that limits predator success when prey populations are low

Type III

200

The increase in predator reproduction rates in response to an increase in the consumption of prey is called the ________ _________

numerical response

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

300

Describes the similarity in color patterns among many unpalatable or venomous species.

Mullerian mimicry 

Parasitism & Mutualism

100

A clear sign of immune response from a parasitic infection and the first-line of defense from a host is _________

inflammation

150

Disregarding its size classification, a tapeworm is an example of what kind of parasite? 

endoparasite

200

This type of mutualist cannot survive without the interaction.

obligate

250

Plant parasites that are photosynthetic but draw water and nutrients from their hosts are known as 

hemiparasites

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

Energetics

100

Plants assimilate energy from solar radiation through this process

photosynthesis

150

Which factor is the primary control of productivity in aquatic systems?

light

200

This is the term used when assimilated energy is used for production of new tissue

secondary production

250

This color of light has wavelengths that are most efficient for photosynthesis

red

300

The river continuum concept suggest that this source of carbon is more prevalent and important in headwater streams.

Allochthonous 

Decomposition

100

Vegetative litter degrades into a homogenous organic component of soil known as 

humus

150

The rate of decomposition is greatest in these two types of environments

warm and moist

200

The decomposition of suspended organic matter and resulting nutrient recycling in the water column critical for fueling primary production is called the

microbial loop

250

Process by which nutrients are converted from an organic to inorganic form that is useable by photoautotrophs is called

Mineralization

300

This is the most recalcitrant form of carbon

Lignin
