Concepts
18 concepts
temporal dynamics
Changes in ecological patterns and processes across different time scales
oviposition host plant choice
The selection of specific plants by female insects for egg-laying that affects larval survival and development
gene flow
Movement of genes between populations through migration and reproduction
individual fitness
balancing selection
Selection that maintains multiple alleles in a population at frequencies above those expected from mutation alone
Larval survival rate
population structure
The organization of genetic variation within and among populations, reflecting patterns of gene flow, drift, and selection
plant density effects
How plant population density affects individual plant growth, morphology, and susceptibility to herbivory through competition and resource availability
population decline
Reduction in population growth rates, size, or occurrence across species ranges
Microclimate Selection Hypothesis
Females should choose nesting sites that best protect them and their offspring from severe or unpredictable weather events, such as extreme temperatures or high wind
larval food stress
Nutritional limitation during larval development that affects adult phenotype
defence polymorphism
Genetic variation in defensive traits maintained within populations
heterozygote deficiency
Lower than expected frequency of heterozygous genotypes in a population
emergence success
nesting aggregation
Multiple individuals of solitary nesting species choosing to nest in close proximity to one another
seed dormancy
A state where viable seeds do not germinate immediately even under favorable conditions
viability selection
Selection on body mass accounting for juvenile survival until reproduction but may weaken after recruitment
metabolic flight capacity
Peak metabolic rate and total energy expenditure during forced flight as measures of dispersal ability
