oligolectic
omnivory
Animals which feed on both plant and prey sources, allowing them to effect multiple trophic levels within a food web
onlap
open system dynamics
Population dynamics in systems characterized by high levels of dispersal and recruitment from external sources
open systems
operational taxonomic units
Term used to represent each morphospecies of culturable fungi in lieu of species name as species has not currently been established by means of sequencing
opportunity cost
Cost of remaining in refuge measured as lost foraging opportunities or other beneficial activities
optimal allocation theory
Theory predicting that parents should allocate investment amongst their progeny according to an optimum at which their own (i.e., the parents') fitness is maximized
optimal cluster size hypothesis
The hypothesis that there is an optimal egg cluster size that maximizes fitness by balancing benefits and costs of aggregation
optimal control theory
optix transcription factor
Transcription factor gene controlling scale development and coloration in butterflies
orbital forcing
Climate changes driven by variations in Earth's orbital parameters affecting incoming solar radiation distribution
ordinal logistic regression
A regression approach that allows for multiple ordered response categories and provides more specific interpretation of exact probability of socioeconomic characteristics on constraints
ore shoots
Local concentrations of ore minerals within veins
organization structure
ortholog hit ratio
Measure of genome annotation quality based on similarity of predicted proteins to reference orthologs
outdoor recreation constraints
Barriers that can be impediments to individuals participating in outdoor recreational activities, often reflected in sociocultural issues
outlier detection
Statistical identification of observations that deviate significantly from expected patterns in meteorological data
ovarian diapause
Reproductive strategy where females delay egg development and deposit eggs in terrestrial habitats during autumn after entering diapause
ovary development
overlap coefficient
A measure of the degree to which two phenological distributions overlap in time, calculated by integrating the area under both probability density curves
overpopulation
Population density exceeding the carrying capacity of available resources, leading to reduced individual condition
oxbow deposits
Diffusion-limited organic-rich deposits that result from river meanders with fine-grained nature producing near-zero rate of water flow
oxygen A-band absorption
Atmospheric absorption of solar radiation by molecular oxygen around 760nm wavelength used for pressure level determination
oxytocin
Neuropeptide hormone often called 'love drug' or 'cuddle hormone' that mediates a suite of behavioral traits ranging from ultrasocial to antisocial
pace-of-life hypothesis
Hypothesis proposing that individuals vary in life-history strategies covarying with suites of morphological, physiological and behavioural characteristics, where fast-growing individuals should be mo...
pace-of-life syndrome
Correlations between boldness and an individual's willingness to face risk for food, linked to growth rate
pace-of-life syndrome
Hypothesis positing that a series of behavioural and physiological axes of variation correlates with the individual slow-fast continuum
paired watershed study
An experimental design using matched watershed pairs to isolate treatment effects while controlling for natural variation
palatability
The acceptability of food items based on taste, texture, and chemical composition
paleo-valley
An ancient valley system that may have influenced past patterns of erosion and exhumation
paleocurrent analysis
Analysis of directional sedimentary structures to determine ancient flow directions
paleoecology
paleoglacier reconstruction
Reconstruction of past glacier extents and ice thickness using geomorphic evidence and numerical modeling
paleomagnetic data
paleosalinity reconstruction
Determination of ancient water salinity conditions using geochemical and paleontological indicators
pan trap sampling bias
The differential attraction of insects to certain colored traps, potentially leading to non-representative samples of the true community
panorama
Large-scale moving or stationary paintings designed to create immersive visual experiences for 19th-century audiences
paragenesis
The sequence of mineral formation and deposition in ore deposits
parallax correction
Geometric correction for apparent horizontal displacement of cloud location due to satellite viewing angle
parallel trends assumption
parasite aggregation
Non-random distribution of parasites among hosts with most hosts having few parasites
parasite-mediated sexual selection
The influence of parasites on sexually selected traits and mate choice decisions
parasitism
Attack by parasitoid species that use lycaenid larvae as hosts for their development
parasitoid wasp DNA
parent-child spatial relationships
parental care trade-offs
The conflicting pressures parent birds face between maintaining optimal nest conditions and foraging to meet metabolic needs
parental desertion model
Theoretical framework predicting when parents will abandon offspring based on costs and benefits of continued care versus seeking additional mating opportunities
parsivoltinism
Life cycle strategy where organisms take more than one year to complete development
partial life-cycle model
Age-structured demographic model where fertility is approximated by an average fertility parameter and age-specific survival from α until death
