Question 1: population ecology
Answer:
The study of factors that cause populations to increase or decrease.
Question 2: resource partitioning
Answer:
When two species divide a resource based on differences in their behavior
Question 3: population distribution
Answer:
A description of how individuals are distributed with respect to one another.
Question 4: k-selected species
Answer:
A species with a low intrinsic growth rate that causes the population to increase slowly until it reaches carrying capacity.
Question 5: demographer
Answer:
A scientist in the field of demography.
Question 6: die off
Answer:
A rapid decline in a population due to death.
Question 7: population growth rate
Answer:
The number of offspring an individual can produce in a given time period, minus the deaths of the individual or its offspring during the same period.
Question 8: community
Answer:
All of the populations of organisms within a given area.
Question 9: limiting resource
Answer:
A resource that a population cannot live without and that occurs in quantities lower than the population would require to increase in size.
Question 10: j-shaped curve
Answer:
the curve of the exponential growth model when graphed
Question 11: population
Answer:
the individuals that belong to the same species and live in a given area at a particular time.
Question 12: keystone species
Answer:
A species that plays a far more important in its community than its relative abundance might suggest.
Question 13: metapopulation
Answer:
A group of spatially distinct populations that are connected by occasional movements of individuals between them.
Question 14: ecological succession
Answer:
The predictable replacement of one group of species by another group of species over time
Question 15: overshoot
Answer:
When a population becomes larger than the environment's carrying capacity.
Question 16: interbreeding depression
Answer:
When individuals with similar genotypes-typically relatives-breed with each other and produce offspring that have an impaired ability to survive and reproduce.
Question 17: doubling time
Answer:
The number of years it takes a population to double. (Rule of 70)
Question 18: commensalism
Answer:
A relationship between species in which one species benefits and the other species is neither harmed nor helped.
Question 19: exponential growth model
Answer:
(Nt = N0ert ) A growth model that estimates a population's future size (Nt ) after a period of time (t), based on the intrinsic growth rate (r) and the number of reproducing individuals currently in the population (N0)
Question 20: demography
Answer:
The study of human populations and population trends.
Question 21: density-dependent factor
Answer:
A factor that influences an individual's probability of survival and reproduction in a manner that depends on the size of the population.
Question 22: secondary succession
Answer:
The succession of plant life that occurs in areas that have been disturbed but have not lost their soil.
Question 23: r-selected species
Answer:
A species that has a high intrinsic growth rate, which often leads to population overshoots and die-offs.
Question 24: net migration rate
Answer:
The difference between immigration and emigration in a given year per 1,000 people in a country.
Question 25: crude birth rate
Answer:
The number of births per 1,000 individuals per year.
Question 26: symbiotic relationship
Answer:
The relationship between two species that live in close association with each other.
Question 27: type 2 survivorship curve
Answer:
A pattern of survival over time in which there is a relatively constant decline in survivorship throughout most of the life span.
