Flashcard 1: What is the reproductive strategy of equilibrium species?
Answer: K-selected strategy. Equilibrium species maintain stable populations near carrying capacity.
Flashcard 2: What is a defining trait of r-selected species?
Answer: High reproductive rates and short gestation. r-selected species prioritize rapid reproduction for population growth.
Flashcard 3: What is a common reproductive strategy for K-selected species?
Answer: Producing few, well-cared-for offspring. Quality strategy invests heavily in each offspring's survival.
Flashcard 4: What is a life history trait of K-selected species?
Answer: Long lifespan. Extended lifespan allows for repeated reproductive opportunities.
Flashcard 5: What is the reproductive strategy of equilibrium species?
Answer: K-selected strategy. Equilibrium species maintain stable populations near carrying capacity.
Flashcard 6: Which species type often experiences boom-and-bust population cycles?
Answer: r-selected species. High reproductive rates cause rapid population increases and crashes.
Flashcard 7: What is a common reproductive strategy for K-selected species?
Answer: Producing few, well-cared-for offspring. Quality strategy invests heavily in each offspring's survival.
Flashcard 8: What is a defining trait of r-selected species?
Answer: High reproductive rates and short gestation. r-selected species prioritize rapid reproduction for population growth.
Flashcard 9: Which species type typically has a longer lifespan?
Answer: K-selected species. Lower mortality rates and investment in survival extend lifespan.
Flashcard 10: What is the reproductive strategy of opportunistic species?
Answer: r-selected strategy. Opportunistic species exploit temporary resource availability rapidly.
Flashcard 11: Which type of species has a higher chance of offspring survival?
Answer: K-selected species. Intensive parental care increases individual offspring survival rates.
Flashcard 12: What is an example of an r-selected species?
Answer: Mice. Small mammals with rapid reproduction and short generation times.
Flashcard 13: Which type of species is more likely to have parental care?
Answer: K-selected species. Investment in fewer offspring allows for extensive parental care.
Flashcard 14: Which species type is more likely to be affected by density-independent factors?
Answer: r-selected species. Population changes driven by external environmental disturbances.
Flashcard 15: What is a key characteristic of K-selected species?
Answer: Long gestation periods and fewer offspring. K-selected species prioritize quality over quantity in reproduction.
Flashcard 16: Identify a factor limiting K-selected species' population growth.
Answer: Carrying capacity of the environment. Population stabilizes near maximum sustainable population size.
Flashcard 17: What is a life history trait of r-selected species?
Answer: Short lifespan. Fast turnover maximizes reproductive output in limited time.
Flashcard 18: How do K-selected species populations typically grow?
Answer: S-shaped logistic growth curve. Population growth slows as it approaches carrying capacity limits.
Flashcard 19: Which type of species has a lower reproductive rate?
Answer: K-selected species. Energy invested in fewer, higher-quality offspring reduces reproductive rate.
Flashcard 20: Which type of species is more likely to be invasive?
Answer: r-selected species. Rapid reproduction enables quick establishment in new habitats.
Flashcard 21: What is the typical population size trend for K-selected species?
Answer: Stable near carrying capacity. Populations remain close to maximum sustainable levels.
Flashcard 22: Which type of species invests more energy in offspring care?
Answer: K-selected species. Fewer offspring allow for greater parental investment per individual.
Flashcard 23: Which species type is better suited for climax communities?
Answer: K-selected species. Competitive advantages suit stable, mature ecosystem conditions.
Flashcard 24: What is the typical population size trend for r-selected species?
Answer: Fluctuates widely. Boom-and-bust cycles create dramatic population changes.
Flashcard 25: What is a survival strategy of r-selected species?
Answer: Maximizing reproduction rate. High reproductive output compensates for environmental uncertainty.
Flashcard 26: What is a survival strategy of K-selected species?
Answer: Investing in offspring quality. Parental investment increases individual offspring survival and fitness.
Flashcard 27: Which type of species is more likely to be an apex predator?
Answer: K-selected species. Large size and competitive ability suit top predator roles.
Flashcard 28: Which type of species is more likely to exhibit territorial behavior?
Answer: K-selected species. Territory defense secures resources for fewer, well-cared offspring.
Flashcard 29: Which species type has typically more offspring per reproductive event?
Answer: r-selected species. High fecundity maximizes reproductive output per breeding cycle.
Flashcard 30: Which species type is better suited for pioneer stages of succession?
Answer: r-selected species. Rapid colonization ability suits early succession environments.
