What is a fire regime?
A fire regime is defined as the frequency, season, intensity, type, and size (area burned) that prevails in an ecosystem.
What are serotinous cones and fruits?
Serotinous cones and fruits are woody structures that store seeds on the mother plant for several years and release them when exposed to the heat of fire.
What is a fundamental niche?
The fundamental niche is the range of environmental conditions under which a species can persist.
What are realized niches?
Realized niches are the actual range of environmental conditions utilized by a species when other species (competitors, predators, parasites) are present.
What is competitive displacement?
Competitive displacement is a reduction in the range of conditions that a species occupies, due to competition with other species.
What is niche partitioning?
Niche partitioning is the process by which natural selection drives competing species into different patterns of resource use.
What is ecological niche modeling?
Ecological niche modeling refers to computational tools to predict the distribution of species across geographic space and time.
What does social behavior include?
Social behavior includes all interactions among individuals of the same species, involving interaction with mates, offspring, other relatives, and unrelated individuals.
What is the many-eyes effect?
The many-eyes effect refers to having more eyes to watch for predators.
What is the dilution effect?
The dilution effect is the reduced risk that you will be the one to become a predator’s supper.
Who are donors and recipients in social behavior?
Donors are individuals initiating behaviors, while recipients are individuals toward whom behaviors are directed.
What is cooperation in social behavior?
Cooperation occurs when both the donor and the recipient of a social behavior experience increased fitness from an interaction (e.g., when a group of lions kill prey).
What is selfishness in social behavior?
Selfishness occurs when the donor of a social behavior experiences increased fitness, while the recipient experiences decreased fitness (e.g., competition for food).
What is spitefulness in social behavior?
Spitefulness is when a social interaction reduces fitness of both donor and recipient, and is not favored by natural selection.
What is altruism in social behavior?
Altruism increases recipient fitness and decreases fitness of the donor.
What is direct fitness?
Direct fitness is the fitness you gain by passing on copies of your genes to your offspring.
What is indirect fitness?
Indirect fitness is the fitness you gain by helping a relative pass on to its offspring copies of genes that the relative shares with you.
What is inclusive fitness?
Inclusive fitness is the sum of direct and indirect fitness.
What is sexual reproduction?
Sexual reproduction is a mechanism in which progeny inherit DNA from two gametes (eggs, sperm), usually from two parents.
What is asexual reproduction?
Asexual reproduction is a mechanism in which progeny inherit DNA from a single parent.
What is vegetative reproduction?
Vegetative reproduction is a form of asexual reproduction in which an individual plant is produced from the nonsexual tissues of a parent.
What are clones?
Clones are individuals that descend asexually from the same parent and bear the same genotype.
What is binary fission?
Binary fission is reproduction through duplication of genes followed by division of the cell into two identical cells.
What is parthenogenesis?
Parthenogenesis is a form of asexual reproduction in which an embryo is produced without fertilization.
