Concepts
15 concepts
interspecific competition
Negative interactions between individuals of different species competing for limited resources
mutualistic relationships
Mutually beneficial herbivore-predator associations where sap-feeding insects provide honeydew food for ants in exchange for protection against predators
facilitative interactions
Positive species interactions such as nurse plant effects by cushion-forming species that increase reproductive success for neighboring plants
tripartite interactions
Interactions involving three species or groups, such as soil microbes, plants, and pollinators
biomass allocation
Distribution of plant growth and resources between aboveground (shoots) and belowground (roots) structures
associative learning
The formation of predictive relationships between contingent stimuli in the environment
colony establishment
Initial colonization phase when winged aphids establish new colonies on host plants
vertical transmission
Transmission of endosymbionts from mother to clonal offspring through the maternal lineage.
honeydew production
The excretion of sugar-rich liquid waste by herbivorous hemipterans feeding on plant sap
experimental treatment
exploitation competition
Competition through depletion of shared resources without direct interaction
hyperaccumulation
parasitoid behavior
Behavioral patterns of wasps that parasitize other arthropods, particularly aphids
top-down control
trophallaxis
The sharing of liquid food resources between nestmates through specialized anatomical and behavioral adaptations
