quantitative resistance
Plant defense that reduces but does not eliminate herbivore performance, mediated by multiple genes with additive effects
queen nest searching
race for life model
Model predicting FID based on combined effects of predator and prey speeds, distances and directions to refuge, and margin of safety
ramet damage
rare species monitoring
Systematic approaches for tracking populations of uncommon or threatened species over time
receiver response
recolonization
recovery
relative weight
An indicator of plumpness defined as 100 times the actual weight divided by the expected weight, suggesting the abundance of food available for each member of the population relative to the energy dem...
relaxed behaviors
Non-vigilant behaviors including foraging, preening, walking, and singing
reliability assessment
The evaluation of how consistently an individual's alarm calls are associated with actual predation risk
reproductive components analysis
Decomposition of total seed production into multiplicative components to identify sensitive life stages
reproductive cycle variation
Seasonal changes in ant colony composition between sexual and worker ant production phases
reproductive ecology
Study of plant reproductive strategies and their ecological consequences
reproductive effort
The relative amount of available carbon that has been allocated to reproductive tissues, calculated as the ratio of carbon allocated to reproductive tissues versus total available carbon
reproductive stage vulnerability
Different stages of reproduction (gestation, lactation, post-reproduction) may predispose females to different levels of roadkill risk due to varying energy demands and foraging behavior
residence time
Average time organisms spend in a given stream reach before drifting, calculated as benthic abundance divided by drift rate
resource use
Individual differences in accessing and utilizing resources such as perches that provide enhanced visibility for predator detection
root presence
safe site model
Model assuming limited number of sites suitable for germination and recruitment with only one juvenile per safe site
sap well density
The number of active sap wells created by sapsuckers per unit area
seasonal relapse
secondary production
The flux of energy through a stream invertebrate by altering individual life-history and development patterns
selection surfaces
selective caching behavior
Differential selection of plant materials for storage based on nutritional quality rather than random sampling of available vegetation
self-thinning
sender condition
sex ratio manipulation
Bees controlling the sex of their offspring via haplodiploid sex determination, with fertilized eggs becoming females and unfertilized eggs developing into males
sex-specific interactions
Differential effects of male versus female neighbors on focal individual fitness due to varying resource needs or allocation patterns
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
sexual readiness
State of being ready for reproduction, measured by cloacal swelling in this study
shade-seeking
shy-bold continuum
Behavioral axis ranging from shy (less interactive, avoidant) to bold (more interactive, approaching) behavioral responses
signal convention reinforcement
site abandonment
situational specificity
The concept that alarm calls can be situationally variable, encoding information about events and stimuli external to callers
social constraints
social fence hypothesis
high density population reduces dispersal because immigration of new individuals will increase negative encounters
social position
social structure
Organization of individuals within populations based on family groups and territorial patterns
social subordination hypothesis
Hypothesis that dominant individuals can force subordinates to leave natal territory through aggression or control over resources
social transmission
The process of scrounging new innovations that can efficiently diffuse novel traits through a population by social learning
society formation
The process by which animals form social groups that share and defend space, distinguish group members from nonmembers, and may persist for many generations
socioeconomic status
The social standing or class of an individual or group, often measured as a combination of education, income and occupation
solitary
solitary species
Species that live alone rather than in groups, potentially making changes in antipredator behavior more impactful to individual survival.
space-use overlap
measure of which individuals share critical resources of burrow sites and foraging areas
spatial proximity
Physical nearness or distance between individuals influencing social interaction probability
spawning
species overabundance
When species limit the abundance or occurrence of other resources or hinder an ecosystem process or human activity
