Data
the "magic number" for a p-value
p< 0.05
measure of how many species in an ecosystem
species richness
1m X 1m square
Quadrat
r=(b+ i)- (d+ e). what do b,i,d and e represent
births, immigration, deaths, emigration
biological species concept
2 animals capable of interbreeding and producing fertile offspring
the value for a regression
R2
what does SDI mean
the chances of having 2 individuals picked at random being different species
line with quadrats at equal intervals
belt transect
how much population an ecosystem can sustain
carrying capacity
T/F asexual species cannot meet standard of biological species concept
True- asexual species dont interbreed
something with a p value of 6.54E^-10
significant difference
species evenness
how even the spread of individuals across species.
trap that is dug into ground
pitfall
use the population graph to determine classification of species by reproduction
r- strategists (from J curve)
concept based on what species look like
morphospecies
which species from the table is the most accurate
Adiantum Spp.
S=√(s/N)
species richness
3 Rs
replication, representative, random
population from 200 original captures, 200 on second capture with 20 recaptures. using N= (M X n)/m
2000
domain, kingdom, phylum, class, order, family, genus, species
when you would use a spearman correlation coefficient
for a non-linear correlation
chances of 2 individuals selected at random being the same species at farm ecosystem- see image
27%
a way to minimise bias that isnt random number generators or sample size
calibrating equipment or setting criteria for data gathering
how would you identify recaptures in an ecosystem
notch on ear, tags, or collars
animal with the scientific name "Ornithorhynchus anatinus"
Platypus
