lecture 4 Flashcards
how does monogamy benefit eusociality
it is better to have full sisters than half sisters because you are more related to full sisters
if inbreeding increases r, why is it bad
inbreeding depression is bad
genetic purging, get rid of bad alleles then not everyone is susceptible to the same level of genetic purging
what is spatial scale
distribution and distribution of species
what is geographical range and structure
geographical range: where to find all pops of species and the potential habitats
structure: distance from one pop to another
what is subpop and metapop
subpop, small pops, subset
metapop, collection of subpop, exchanges genetic info
what is pop abundance and pop size
abundance: species per unit area
pop size: how many individuals are in a pop
what is random distribution
individuals have no affect on one another
seeds dispersed or left behind
what is clumped distribution
clumped for resource
what is uniform distribution
negative interactions to have more space
how to use qudrats
find average in quadrats counted then multiply byall the quadrats there are
how to use mark recapture method
N/M=n/R
what are the effects of too much or too little flow
too much: lose structure
too little: isolated pops
what is levin’s metapop concept
assumes 100% extinction or colonization
habitat matrix prevents too much gene flow, but there is still some
events are not synchronized
local extinctions and local colonizations happen in a cycle with stochastic events
what are corridors
areas for gene flow to maintain structure
moss experiment
