Concepts
20 concepts
genotype by environment interaction
Differential expression of genotypes across environmental conditions, indicating genetic variation in phenotypic plasticity
drought resilience
Ability of forest ecosystems to maintain function during water-limited conditions through adaptive water use strategies
evolutionary trap
When previously adaptive traits become maladaptive due to rapid environmental change, such that organisms are attracted to resources that reduce their fitness
climate change effects on behavior
How changing weather patterns and climate conditions influence animal behavioral strategies
pleiotropic effects
When single genes or alleles influence multiple, seemingly unrelated traits
population decline
Reduction in population growth rates, size, or occurrence across species ranges
adaptive polymorphism
Genetic variation maintained in populations by natural selection where different alleles are favored under different conditions
larval food stress
Nutritional limitation during larval development that affects adult phenotype
leaf mining behavior
Feeding behavior where insect larvae create tunnels within plant leaves between epidermal layers
shade avoidance syndrome
Suite of plant responses to shade including stem elongation, reduced branching, and accelerated flowering to compete for light
chemical defences
chromosomal inversion
Chromosomal rearrangement where a segment is reversed in orientation, potentially suppressing recombination and maintaining linkage between beneficial alleles
defence polymorphism
Genetic variation in defensive traits maintained within populations
heterozygote deficiency
Lower than expected frequency of heterozygous genotypes in a population
light gradient
Environmental gradient of light availability from open sun through intermediate shade to deep shade habitats
cross-resistance
When prior infection by one natural enemy affects the plant's resistance or susceptibility to attack by a different natural enemy
ecological trap
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
