consumer-resource interaction
core microbiome
A set of organisms present across multiple sites that are not statistically associated with any specific location and represent shared metabolic potential
cover of bare ground
damage by adult B. pulicarius
decoupling
discovery ability
Having the ability to discover resources quickly due to high foraging efficiency or abundance
disturbance regime
Pattern of ecological disturbances created by beaver activity that favors species adapted to highly variable environments
dominance-impoverishment rule
The rule predicts that species diversity should decrease linearly as the number or abundance of dominant species increases.
double benefit hypothesis
The hypothesis that caddisflies gain nutritional benefits both from consuming conditioned detritus and from consuming algae that grows from nutrients released during detritus processing
drift propensity
A measure of drift standardized by the benthic density of the source population, calculated as drift density divided by benthic density
dust aversion hypothesis
hypothesis that animals will avoid feeding in areas with high dust deposition
eavesdropping
Recognizing and gleaning information from a communication intended for someone else
ecological dominance
Having the greatest foraging success relative to abundance in the environment
ectoparasite
Parasites that live on the external surface of their hosts
ectoparasitism
External parasitic infestation that can be costly to avian hosts, causing feather and skin damage as well as anemia due to blood loss
emergent aquatic insects
Insects that complete larval development in aquatic systems and emerge as adults into terrestrial environment, serving as important link between freshwater and terrestrial ecosystems
enemy release hypothesis
enemy release hypothesis
Exotic species benefit from the loss of a subset of their natural enemies during immigration
enemy-free space hypothesis
epiphyte
facilitated exploitation
A phenomenon where the action of one exploiter species opens the opportunity for exploitation by a second species
fish predation
Consumption of aquatic or semi-aquatic insects by fish during oviposition or other water surface activities
floral bullseye size
flower piercing
foliar traits
Leaf-level characteristics including nitrogen content, carbon content, leaf mass per area, and water content that can be measured and mapped using spectroscopy
foraging patterns
Temporal and spatial patterns of ant foraging behavior on extrafloral nectaries throughout the day and season
functional convergence
Process where remaining plant community converged functionally toward a species composition whose traits resembled the previously removed dominant species
functional divergence
functional evenness
functional group composition
Classification of species based on ecological traits like nesting habits, diet, sociality, and body size rather than phylogenetic relationships
fungal community composition
Diversity and abundance of fungal morphotypes colonizing organic substrates
fungal infection
Infection of aspen trees by heartrot fungus that softens wood for cavity excavation
graded signals
Communication signals that vary continuously rather than discretely to convey information about intensity or degree
green trophic pathway
The algal trophic pathway involving primary production and photosynthesis
grooming attenuation coefficient
grooming behavior
guild
Taxonomically or functionally related species grouped together, such as trophic levels, functional groups, and guilds
herbivory simulation
Experimental clipping treatment to reduce photosynthetic capacity and stress plant-fungal associations
herbivory threshold
Critical point where herbivore grazing pressure begins to regulate algal biomass rather than resource limitation
homogenizing selection
Community assembly process where environmental conditions favor similar microbial communities, resulting in communities more similar than expected by chance
honeydew
host manipulation
host range expansion
host-vector interaction
hummingbird flower syndrome
The convergent set of floral traits (red color, tubular morphology, dilute nectar) expected to evolve in flowers adapted for hummingbird pollination
humped-back model
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...
hydraulic refugia
Areas of low velocity and reduced hydraulic stress that provide shelter for aquatic organisms from strong flow forces
