Concepts

The hypothesis that caddisflies gain nutritional benefits both from consuming conditioned detritus and from consuming algae that grows from nutrients released during detritus processing

A measure of drift standardized by the benthic density of the source population, calculated as drift density divided by benthic density

hypothesis that animals will avoid feeding in areas with high dust deposition

Recognizing and gleaning information from a communication intended for someone else

Having the greatest foraging success relative to abundance in the environment

Parasites that live on the external surface of their hosts

External parasitic infestation that can be costly to avian hosts, causing feather and skin damage as well as anemia due to blood loss

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

Exotic species benefit from the loss of a subset of their natural enemies during immigration

A phenomenon where the action of one exploiter species opens the opportunity for exploitation by a second species

Consumption of aquatic or semi-aquatic insects by fish during oviposition or other water surface activities

Leaf-level characteristics including nitrogen content, carbon content, leaf mass per area, and water content that can be measured and mapped using spectroscopy

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

Process where remaining plant community converged functionally toward a species composition whose traits resembled the previously removed dominant species

Classification of species based on ecological traits like nesting habits, diet, sociality, and body size rather than phylogenetic relationships

Diversity and abundance of fungal morphotypes colonizing organic substrates

Infection of aspen trees by heartrot fungus that softens wood for cavity excavation

Communication signals that vary continuously rather than discretely to convey information about intensity or degree

The algal trophic pathway involving primary production and photosynthesis

Taxonomically or functionally related species grouped together, such as trophic levels, functional groups, and guilds

Experimental clipping treatment to reduce photosynthetic capacity and stress plant-fungal associations

Critical point where herbivore grazing pressure begins to regulate algal biomass rather than resource limitation

Community assembly process where environmental conditions favor similar microbial communities, resulting in communities more similar than expected by chance

The convergent set of floral traits (red color, tubular morphology, dilute nectar) expected to evolve in flowers adapted for hummingbird pollination

A model suggesting that plant diversity peaks at intermediate productivity, is low at high productivity where few species dominate available resources, and is low at low productivity where few species...

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