Concepts

Variation in interspecific interactions across time periods over which organisms co-occur that leads to flexible network structure

The positive relationship between species richness and the surveyed area, described by the power-law S=cA^z where c is the intercept and z measures the rate of community turnover

Loss of species diversity through various processes including lack of adaptation to changing conditions, phenological changes, shifts in species abundance and ranges, and habitat loss

Alpine plants growing in clumps with multiple species interacting in close proximity, affecting microhabitats and species interactions

Temporal alignment between consumer energy requirements and food source availability across trophic levels

Chemical cues released by predators that benefit prey by providing information about predator presence

Bacterial communities that colonize and live within floral nectar, potentially affecting nectar chemistry and pollinator behavior

The tendency for flower foragers to visit a single flower species during foraging trips even when alternative rewarding species are available

Effects of human recreational activities on wildlife communities through habitat alteration, disturbance, and behavioral changes

Social ranking system based on agonistic interactions where some individuals consistently dominate others

The degree to which parasites show preference or restriction to particular host species rather than being generalist

Internal aboveground symbionts living within plant tissues that can produce alkaloids for plant defense

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

Shift toward woody plant encroachment into nonwoody meadows and grasslands

Species-specific selection for particular combinations of physical habitat characteristics like water depth, current velocity, and substrate size

Tree mortality and ecosystem disruption caused by bark beetle infestation, resulting in pulsed release of conifer needles and altered biogeochemical cycling

Behavior where caddisfly larvae consume material from their own or others' protective cases

Daily behavioral pattern where aquatic organisms move vertically in the water column, typically showing different activity levels during day versus night periods

Chemical compounds overproduced by queens compared to workers that potentially regulate worker reproduction

The tendency of foragers to maintain a consistent foraging strategy across multiple floral visits rather than switching between different tactics

When organisms switch from their primary food to secondary food sources under conditions of high competition or resource limitation

Chemical signals that organisms use to obtain information about their environment

When prior infection by one natural enemy affects the plant's resistance or susceptibility to attack by a different natural enemy

Differential prey use based on habitat type, with fairy shrimp comprising majority of diet in temporary ponds

Decrease in compositional similarity between communities with increasing geographic distance or environmental separation

A habitat not well suited for survival and reproduction that animals are attracted to for foraging if the threat of vehicles is not recognized

Algae growing attached to surfaces such as decomposing plant material

Seeds present in the soil that represent the potential for future plant community recruitment and composition

The relationship between the microbiome and sociality in animals

When plants are found adjacent to one another with less than two finger-widths between them or when one plant surrounds another

Communities of cyanobacteria, lichens, and mosses that live on soil surfaces and contribute to soil stability and fertility

Simultaneous attack of hosts by multiple enemies, in this case herbivores and bacterial pathogens

Parasites that live on the external surface of their hosts

Insects that complete larval development in aquatic systems and emerge as adults into terrestrial environment, serving as important link between freshwater and terrestrial ecosystems

Temporal and spatial patterns of ant foraging behavior on extrafloral nectaries throughout the day and season

Areas of low velocity and reduced hydraulic stress that provide shelter for aquatic organisms from strong flow forces

Imbalance between carbohydrates and protein availability that affects ant behavior and foraging strategies
