Ecology of ants

Ant Mosaics and Dominance

ants role in ecosystems
Ants` role in ecosystems
  • 40-60% of all animal biomass
  • predation & scavenging
ants role in ecosystems1
Ants` role in ecosystems
  • niche diversification
  • structuring

the invertebrate

community

community ecology of ants
Community ecology of ants
  • convenient model organisms
  • modular, sessile organisms
  • parallel with plants
ant functional groups
Ant Functional Groups
  • Andersen 1986
  • parallel to

Grime`s

classification

Dominant

Dolichoderinae

Subordinate

Camponotini Generalized

Myrmicinae

ant mosaics
Ant Mosaics
  • groups of particular co-occurring ant species
  • specific functional groups
  • positive & negative associations

ant dominance
Ant Dominance
  • space and food resources monopolization
  • different types of dominance:

1. Ecological

2. Behavioural

3. Numerical

ant dominance1
Ant Dominance
  • cca. 150 of 12 000 species referred as dominant

Dolichoderinae

Formicinae

Myrmicinae

ant dominance2
Ant Dominance
  • trophobiosis
  • arboreal ants
  • nitrogen gained from

lower trophic levels
