75 concepts
light gradient
Environmental gradient of light availability from open sun through intermediate shade to deep shade habitats
nutritional ecology
Study of how organisms obtain and use nutrients and how nutrition affects fitness
reactive oxygen species
Oxygen-containing reactive molecules with considerable environmental importance due to their high reactivity in mediating redox transformations
vernalization
Requirement for extended cold treatment to trigger flowering in some plant species
BC-ratio
The proportion of aliphatic GS derived from branched-chain amino acid (Val and Ile) precursors, representing quantitative trait variation controlled by known biosynthetic locus
Bateman's index
Constancy index that distinguishes between complete constancy, random transitions, and complete inconstancy
biophysical models
Tools implemented to accurately predict an organism's physiological response to attributes of interest such as water loss and body temperature
comparative genomics
Approach to compare genome features across multiple species to identify conserved and variable elements.
cross-resistance
When prior infection by one natural enemy affects the plant's resistance or susceptibility to attack by a different natural enemy
cue similarity
The degree to which novel resources resemble historical resources in their chemical or physical cues
differential gene expression
Genes that show significantly different expression levels between treatment conditions
ecological trap
emergence success
genome polishing
Computational method to improve genome assembly accuracy by using short reads to correct errors in long-read assemblies
heat shock proteins
Molecular chaperones that help cells cope with protein folding stress under adverse conditions
matrix resistance
The relative difficulty of movement through different types of non-habitat matrix surrounding habitat patches
microevolution
Genetic change in a trait if there is heritable variation, selection, and heritability
nesting aggregation
Multiple individuals of solitary nesting species choosing to nest in close proximity to one another
predator-prey interactions
Interspecific interactions between caddisfly larvae and their predators affecting case size and behavior
seed dormancy
A state where viable seeds do not germinate immediately even under favorable conditions
soil sterilization
Experimental technique to remove soil microbial communities via autoclaving
viability selection
Selection on body mass accounting for juvenile survival until reproduction but may weaken after recruitment
color discrimination
metabolic flight capacity
Peak metabolic rate and total energy expenditure during forced flight as measures of dispersal ability
