Concepts

Interactions involving three species or groups, such as soil microbes, plants, and pollinators

Distribution of plant growth and resources between aboveground (shoots) and belowground (roots) structures

Introduction of natural enemies to reduce pest population density through environmentally friendly means

Nectar-secreting organs located on leaf laminae, petioles, rachis, bracts, stipules, pedicels, or fruit that attract arthropods

How male and female plants of dioecious species differ in their interactions with insects

The formation of predictive relationships between contingent stimuli in the environment

Initial colonization phase when winged aphids establish new colonies on host plants

Experimental design testing multiple factors simultaneously in all combinations

Sugar composition of plant phloem sap which honeydew is derived from, potentially altered by temperature affecting ant recruitment or tending behavior

Experimental design where subjects choose between two alternative options to assess preferences

Method for quantifying the proportion of overall variance explained by different factors or pathways using R² calculations

Transmission of endosymbionts from mother to clonal offspring through the maternal lineage.

Non-living environmental factors such as climate, light, and temperature that influence organism performance

The excretion of sugar-rich liquid waste by herbivorous hemipterans feeding on plant sap

The abundance or availability of resources in a given area

The concept that higher trophic levels are more sensitive to environmental change due to their smaller population sizes and greater environmental demands

The accumulation of substances like sodium in organisms through their food chain, allowing carnivores to obtain adequate salt from prey

Chemical compounds with therapeutic or biological activity

Chemical signals that organisms use to obtain information about their environment

The balance between costs and benefits that determines whether species interactions are mutualistic or antagonistic

The hypothesis that species that are competitively dominant have reduced ability to discover new resources quickly

Behavioral patterns of wasps that parasitize other arthropods, particularly aphids

Sampling method using buried containers with killing solution to capture ground-dwelling invertebrates

Experimental technique to prevent predator access while maintaining other ecological interactions

Aphid colony growth rate calculated as ln(n1)-ln(n0)/t where n1 and n0 are final and initial colony sizes

The sharing of liquid food resources between nestmates through specialized anatomical and behavioral adaptations

Having the greatest foraging success relative to abundance in the environment
