Good colonizer, tolerate harsh conditions, makes environment friendly for other species
What is R-species or Pioneer species
100
What percent of energy is passed on at each trophic level?
What is 10 percent?
100
What is positive feedback and negative feedback?
What is Positive: changes in environment that further accelerate global warming. Negative: changes in environment that cause uptake of CO2 reduce global warming
100
Why are you more vulnerable on edge of habitat?
What is higher invasive species rates, worse soil, lower fitness?
100
4 reasons being in a group helps fitness...
What is Dilution, Confusion, Group Defense, Detection of Predation
200
Stable, final community from ecological succession
What is Climax community
200
Substance increases in concentration at higher trophic levels
What is Biomagnification?
200
What is NPP?
What is rate at which biomass is produced?
200
What is a wildlife corridor?
What is strip of undeveloped habitat that connects preserved areas?
200
Equilibrium number is influenced by what?
What is Island size and location (proximity to mainland)?
300
One Pathway energy flows among trophic levels
What is Food Chain
300
(Double Jeopardy) How gain nutrients in ecosystem? (3 reasons)
What is Weathering of rocks, Nitrogen fixing bacteria, deposition by wind, water?
300
When predator develops trait and then prey develops trait to counteract then predator back and forth..
What is Coevolutionary arms race?
300
Manage and use of resources only as fast as being replenished
What is sustainability?
300
What is a stochastic event and examples? Why does it pose a threat to small populations?
What is Chance event examples: fires, floods, disease etc. Increases probability of small populations going extinct
400
When changes in top-down control affects changes two or three links away
What is Trophic Cascade
400
Rate at which nutrients cycle limited by what? And what influences the limiting thing?
What is Rate of decomposition of detritus? Influenced by abiotic factors (oxygen, temperature etc.) and by quality of detritus (high in Nitrogen and low in lignin is good)?
400
(Double Jeopardy) Difference between parasitism and predation? 3 ways parasite changes host and benefits to parasite?
What is differences: parasite usually smaller than host and doesn't kill host. Parasite changes morphology of host ex: better attachment/growth of parasite to host, changes in behavior of host ex- helps parasite get passed on, countering host immune system ex: keep parasite alive
400
Preservation of species in artificial settings
What is Ex situ conservation?
400
What happens as species richness increases on island to the immigration and extinction rates and why?
What is Immigration rates decrease and extinction rates increase?
500
Why greater species richness equals greater resilience and resistance? (2 reasons)
What is Less likely to be wiped out by disturbance and less likely for invasive species to take over; niches already filled
500
Tell me or better yet draw out the complete carbon and nitrogen cycles and narrate while you do so?
What is (see drawing)?
500
The 6 things a prey will try to not get eaten...
What is escape behavior, armor weapons/active defenses, mimicry, camouflage, defensive chemicals/warning coloration, school/flock/herd formation?
500
What is biggest threat to biodiversity of terrestrial species, freshwater species, marine species and mammal species?
What is Habitat degredation or destruction, pollution, overexploitation, overhunting?
500
What does a p-value tell you in a T-test, Linear regression test and Chi-squared test?
What is T-test: there is a relationship between continuous variable and categorical variable. Linear regression: one variable is affecting another. Chi-squared: relationship between continuous variables?
