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

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
