Life history - Answer: individual (vary phenotypically)
Life history strategy - Answer: summarizes typical range or
average values
for all life history traits for a population/ species
,LHS is response to - Answer: Physical conditions
-temp effects growth rate, stress level, food availability
Food supply
Predators
Competiton
Different pressures result in - Answer: different LHS among
species
Clutch size determined by - Answer: ability of parents
Different environmental pressures result in - Answer: diffeent LHS
among populations (location of ginseng)
Phenotypic plasticity - Answer: When a genotype can display a
range of phenotypes depending on environmental conditions
(NB adjust growth rate but NJ doesn't)
(plants increase root growth when h20 is scarce)
Plasticity in LHT can cause - Answer: variability in adult morph
, (height vs width in ponderosa pine pop)
(length vs width in dif spadefoot toad pops)
Polyphenism - Answer: distinct, discrete morphologies (morphs)
arise from a single genotype
as a result of differing environmental conditions (not continuum)
Plasticity vs. acclimatization - Answer: acc - short term
pheno changes not related to acc may or may not be reversible
(body shape)
plas enables acc, determines extent
Plasticity vs. adaptation - Answer: adap = pop changes from
natural selec for beneficial trait
all abilities to acclimat and plasticity degree are adaptations
Optimal life history - Answer: One that maximizes an
individual's contribution
to future generations
(i.e. reproduction)
