Predator-prey Interactions
Concepts
Beneficial Interactions Between Species #
Diversity and scale
Diversity and Latitude
Predator selection among Multiple Prey
Competition Between Species
One Predator, One prey
Apparent Competition
Metapopulations in Patchy Enviroments
Interconnections of species: food Chains and Food Webs
Food chains
Food webs
Interaction of spiceies
communities
community restoration
climax community
habitat
habitat loss
habitat fragmentation
large=more diverse
more populations
Species-area relationship
north= less diverse
climate
prey-dependent
functional response
zero growth isocline
paradox of enrichment
choice of prey #
probability of encounter
decision after encounter
ease of consumption
optimal foraging theory
exploitation competition
interface competion
shared recources
not actually competing for recources
mutualism
both benefit
facilitation
one helps but gets no benefit
nurse plants
source habitat
sink habitat
low quality
high quality
four assumptions
occupation
colonization by migration
location #
local extinction
location factors with diversity
choose one predator
network of prey
energy flow web
keystone species
food chains also are determined by choices
