Chapter 12 - Predation and Herbivory Flashcards
A trophic interaction where a predator consumes a prey
Predation
The one that consumes an individual
Predator
The one that is being consumed
Prey
Predation wherein the predator and prey are both animals
Carnivory
Predation where the predator is an animal, while the prey is either a plant or algae
Herbivory
Predation where the predator lives in symbiosis with its prey
Parasitism
Close physical and/or physiological contact between the predator and its prey
Symbiosis
What do you call the predator in parasitism
Parasite
What do you call the prey in parasitism
Host
Parasites that can cause disease in their hosts
Pathogens
Insects that typically lay one or few eggs on or in another insect
Parasitoids
T/F: Carnivores have narrow diets
F - remember na mobile ang preys here so di sila pwede maging choosy hahah kasi mahirap humuli :3
Function of search time or the time it takes to search and find prey
Encounter time
Time it takes to subdue and consume the prey
Handling time
T/F: herbivores are specialists
T - again, narrow diets sila then broad diets if carnivores
Predators blend into their environment so well that prey may be unaware of their presence until it is too late
Mimicry
Species that often contain powerful toxins are ____ colored
Brightly
Provide protection from predators which may instinctually avoid prey that are brightly colored or may learn from experience not to eat them
Warning (aposematic) coloration
Form of mimicry where species have a shape or coloration that provides camouflage, allowing them to avoid detection by predators
Crypsis
T/F: asawa ba ako ni shohei, mingyu, wonwoo, zhou, sebastian, jaekyung, taesoo, etc.?
T - subukan mong mag F
Form of mimicry where the shape and coloration mimic those of a species that is fierce or that contains a potent toxin
False advertising
Allows plants to hide (in time) from seed-eating herbivores, then overwhelm them by sheer numbers
Masting
Occurs when removal of plant tissues stimulates a plant to produce new tissues, allowing for relatively rapid replacement of the material eaten by herbivores
Compensation
____ defense is stimulated by herbivore attacc
Induced
The wide variety of chemicals that plants produce that function to reduce herbivory
Secondary compounds
T/F: the production of secondary compound is an induced defense
T hahahahhahahahahahahhaha
Compounds that deter herbivores directly
Toxic secondary compounds
Compounds that deter herbivores indirectly by attracting predators and parasitoids
Volatile compounds
What do you call the model that represents the dynamics of predator-prey interactions?
Lotka-Volterra predator-prey model
- ALFRED LOTKA AND VITO VOLTERRA
The condition in which the population size of the prey does not change in size for a given number of predators
Isocline OR zero population growth isocline
Magnitude by which predator and prey numbers rise and fall
Amplitude of the cycle
Alternating phases of population growth and decline
Boom bust cycle
