trend estimation
trophic cascade
Indirect effects of ant nutrition on aphid populations and natural enemy abundance mediated through changes in ant behavior
trophic transfer efficiency
The efficiency with which energy is transferred between trophic levels in food webs
tropospheric profiling
tundra vegetation change
Directional changes in plant community composition, abundance, and structure in tundra ecosystems over time
turnover time
The average time required for dead wood to decompose, calculated as the inverse of the decay rate constant
uncertainty
Difference in means of the distributions when the difference in means is smaller, the stimulus is more uncertain and the state of the world is more ambiguous
uncertainty propagation
Statistical approach that carries forward uncertainty from one stage of analysis to subsequent modeling stages
underrepresented minority students
Students from racial/ethnic groups that are underrepresented in STEM fields
unidirectional percolation
uniparental care
Parental care provided by only one parent, either male or female
univoltine
Having one generation per year, characteristic of high-altitude mosquito species
utility values of research
vaccine efficacy
vagility
Dispersal ability or mobility of an organism
valley width
value of information
The change in the animal's expectation of the state of the world after receiving stimulus information
values alignment
The extent to which students see their personal values as aligning with values of the scientific community.
valve morphology
The structural characteristics of diatom valves including shape, size, and ornamental features
vapor depositional growth
variance inflation factor
vector competence
vector mosquito autogeny
vegetation boundaries
Multi-scalar or hierarchical entities where environmental conditions act as site-dependent filters of varying degree to create a present landscape
vegetation density patterns
Spatial distribution of plant species abundance in relation to ant nest locations
vegetative overlap
Spatial overlap between plant canopies used as a proxy for microenvironment modification strength
vegetative structural complexity
Suite of variables including foliage height diversity, average height, coefficient of variation in height, willow frequency, patchiness, and cover
venation theory
Theory predicting that variation in leaf venation network geometry implies physiological trade-offs that then generate LES correlations.
vesicular stomatitis
Vector-borne livestock disease caused by vesicular stomatitis viruses that produces blister-like lesions on muzzle, lips, tongue, and other areas
viewshed analysis
GIS tool used for determining general visibility from specific locations to assess predator detection capability.
vigilance
Head up while sitting or walking, or sitting upright on haunches and surveying surroundings
virulence evolution
visual cues
Light-based signals that influence animal behavior and decision-making
visual culture
The study of how visual technologies and representations function within broader cultural and economic systems
visual documentation
The use of paintings and photographs to record and represent industrial and environmental processes
visual obstruction effects
How physical barriers affect an animal's ability to detect predators and influence anti-predatory behavior patterns
vocal learning
volatile organic compound degradation
Microbial breakdown of plant-emitted volatile compounds such as monoterpenes for carbon and energy sources
volatile organic compounds
Chemical compounds emitted by carcasses that attract carrion feeders and can be suppressed by burial and maintenance behaviors
volumetric approach
volution
volution coiling
vulnerability index
A quantitative measure of forest growth sensitivity to climate change based on correlations between historical growth and climate data
water conservation payments
water conservation policy
Policy approaches to reduce agricultural water consumption through compensation mechanisms and voluntary conservation programs
water discharge
watershed flashiness
weight-length relationship
Mathematical relationship between fish weight and length represented by the improved model W(L)=1000(L/L1)^b
weighted gene coexpression network analysis
Method to identify modules of coexpressed genes and relate them to phenotypic traits
western genre
Film genre characterized by frontier settings, masculine heroism, and themes of civilization versus wilderness
