Concepts
35 concepts
floral visitation rate
Frequency of pollinator visits to flowers measured as visits per individual per minute or visits per flower per minute
nectar traits
Nectar volume, nectar sugar concentration, and total nectar sugar content measured from individual flowers
floral abundance
The total number of flowers available as nectar and pollen resources measured as flowers per meter
floral morphology
The structural characteristics of flowers, categorized as complex or open based on accessibility to pollinators
pollen provision composition
floral resources
Availability of flowering plants that provide pollen and nectar for bee reproduction, quantified as floral density in standardized plots
flower color
foraging efficiency
A measure of how successful a bird is at food acquisition, quantified through observations as foraging rate (number of forages divided by time observed)
lecty
Diet breadth of bees classified as oligolectic (collect pollen from flowers in multiple plant families) or polylectic (collect pollen from flowers in just one family)
spatial autocorrelation
The degree to which values at nearby locations are correlated, used to assess spatial clustering in disease patterns
sex ratio
Population parameter measuring the relative frequency of males and females, specifically operational sex ratio of flowering individuals
corolla length
The length of flower tubes, which correlates with bumble bee proboscis length and determines flower accessibility
host plant quality
fruit set
metabarcoding
The identification of species from environmental DNA samples using target capture sequencing and database matching
floral longevity
The duration from when a flower's corolla first opens until either the corolla falls off or the stigma closes after opening
flower sex phases
Sequential developmental stages of individual flowers progressing through male phases (M1, M2), inter-phase, and female phase
individual-based rarefaction
Statistical method to compare species richness across samples by generating accumulation curves based on individual encounters
herkogamy
critical thermal maximum
The upper thermal limit when the bumblebee loses its motor function as a result of high temperatures
season length
Duration of favorable conditions for bee development and reproduction, shorter at high elevations
alkaloids
amino acids
conspecific density
The number of flowering individuals of the same species in the local area during an individual's peak bloom
critical thermal maximum
Upper temperature limit where organisms lose fitness and performance ability
distributional moments
Mathematical moments describing trait distributions including mean, variance, skew and kurtosis that characterize central tendency, spread, asymmetry and tail behavior
foraging investment
The energetic cost of provisioning brood cells, measured by number of foraging flights per completed cell and provision mass
organic functional groups
pollinator exclusion
Method of covering flowers with mesh bags to prevent pollinator access and allow nectar accumulation for sampling
provision weight
style length
tongue length
functional evenness
handling time
handling time
The duration a pollinator spends foraging on each flower, calculated by dividing total foraging bout duration by number of flowers visited
