BIOL 127 Lecture Notes - Lecture 2: Serpentine Soil, Heliconius, Spruce Budworm
Document Summary
January 10th, 2018: characteristics of population, we want to define the time interval, space where the population is found, what is a population, populations have collective or emergent properties: That individuals don"t have and emergent properties of biological organization above a population: where the meadow really is, conconcered with number of individuals that are there at different times, special cases, deme. Metapopulation: small local populations: example of this is a checkerspot butterfly, larvae is found on serpentine soils (high in mag, low in calc, have toxins and toxic chemicals, etc. ) Diversified from other populations but not reproductively isolated. Morphs can interchange genes even though they look very different: example: heliconius butterflies, different morphs of the same species, hybrids between the morphs, evolved a similar color pattern, share common predators. Predators have learned uliarian mimicry (distasteful: form races, can interchange genes (but are infrequent, partial populations. Different developmental stages: special cases: partial populations, holometabolous: wings develop internal.
