population transience
Higher frequency of movement into and out of habitat patches, as indicated by more abandoned middens in smaller patches
positioning periodicity
positive frequency dependence
predation risk
Risk of being consumed by predators, which differs between fish-containing and fishless streams
prey aggregation
The clustering of prey organisms in particular locations or habitats
primitively eusocial
Bee social organization with multiple broods per year, cooperative breeding, and castes, but with small morphological differences between castes compared to fully eusocial species.
prior experience
problem-solving behaviors
pseudoflower formation
Developmental hijacking where infected plants produce bright yellow flower-like clusters that mimic co-occurring blooms to attract pollinators for pathogen reproduction
puddling behavior
A form of supplemental feeding for nectivorous Lepidoptera to acquire necessary mineral nutrients, primarily sodium, that are otherwise absent from their nectar diets
quantitative resistance
Plant defense that reduces but does not eliminate herbivore performance, mediated by multiple genes with additive effects
rarity
Species characterized by low local abundance and small geographic range size
redox gradients
Sharp redox gradients that favor the generation of ROS, created by mixing between waters with largely different chemical compositions
redox microsites
Non-majority spatially heterogeneous soil volumes possessing conditions differing from the bulk matrix, where internal oxygen consumption exceeds the rate of oxygen supply
redox zones
redox-active mountainous floodplain sediments
regression to the mean
relatedness asymmetry
Difference in genetic relatedness that workers have to brothers versus sisters due to haplodiploidy in Hymenoptera
remote undergraduate research experiences
Undergraduate research programs conducted entirely or primarily at a distance using online technologies and virtual interactions
reproductive cycle variation
Seasonal changes in ant colony composition between sexual and worker ant production phases
residual layer
Remnant of previous day's mixed layer that persists aloft after surface cooling and formation of stable nocturnal boundary layer
resource availability
The availability of food resources which may affect severity of ectoparasitic infestation, manipulated through food supplementation treatments
rock glacier
Lobate or tongue-shaped masses of rock and ice that form under cold climates in alpine regions and at high latitudes
root bimodality
rosette growth form
Plant architecture where leaves are arranged in a circular pattern close to the ground before bolting
rural poverty
saprolite
Weathered bedrock zone between soil and unweathered bedrock that retains original rock structure
satellite availability
The temporal patterns of GPS satellite accessibility affecting positioning accuracy
scale-free networks
Networks where the degree distribution follows a power law, giving similar properties such as robustness to random removal of individuals
seasonal isolation
Periods when remote ecosystems become inaccessible due to winter conditions like snow and ice cover
seasonal streamflow variation
Variations in water quality concentrations due to observed seasonal streamflow fluctuations, with smaller concentrations noted through the 1980-81 period for sampling sites downstream from mine draina...
self-similarity
A thing is self-similar if it does not vary over spatial scales
sensor drift
sex-specific climate response
Differential responses between sexes to environmental variation potentially creating imbalance in the frequency of males and females
sexual dimorphism in immune response
Marked differences between sexes in immune response, with males often having smaller spleens and higher testosterone levels linked to immunosuppression
signal synchronization
Temporal coordination of different signal components within multimodal displays
site abandonment
small-world networks
Networks with a combination of highly clustered subgroups and short average path lengths, efficient for communication
snow heterogeneity
Spatial fragmentation of snow cover, referring to patchiness conditions
social mobility
The ability of individuals to move up or down in socioeconomic status within their lifetime
social structure
Organization of individuals within populations based on family groups and territorial patterns
soil nitrogen saturation
Loss of biodiversity and decreased soil nitrogen retention when nitrogen availability exceeds plant demand
solitary bees
Bee species where females provision individual nests independently, comprising over 85% of bee species but receiving less research attention than eusocial species.
specialist herbivore
Herbivorous insects that have evolved to feed on glucosinolate-producing plants without deleterious consequences
species overabundance
When species limit the abundance or occurrence of other resources or hinder an ecosystem process or human activity
sperm storage
Retention of viable sperm in female spermatheca after mating for extended periods allowing delayed fertilization
spring freshette
status signaling
stooling
structural breakpoint
Unexpected or sudden changes over time in time series, representing shifts in temporal patterns of meteorological variables
