Yet More “Weeds” in the Garden: Fungal Novelties from Nests of Leaf-Cutting Ants
BACKGROUND Symbiotic relationships modulate the evolution of living organisms in all levels of biological organization. A notable example of symbiosis is that of attine ants (Attini; Formicidae: Hymenoptera) and their fungal cultivars (Lepiotaceae and Pterulaceae; Agaricales: Basidiomycota). In recent years, this mutualism has emerged as a model system for studying coevolution, speciation, and ...
متن کاملFungal-Fungal Interactions in Leaf-Cutting Ant Agriculture
Many organisms participate in symbiotic relationships with other organisms, yet studies of symbioses typically have focused on the reciprocal costs and benefits within a particular host-symbiont pair. Recent studies indicate that many ecological interactions involve alliances of symbionts acting together as mutualistic consortia against other consortia. Such interacting consortia are likely to ...
متن کاملFungal endophyte effects on leaf chemistry alter the invitro growth rates of leaf-cutting ants' fungal mutualist, Leucocoprinus gongylophorus
Fungal symbionts that colonize leaf tissue asymptomatically (endophytes) can alter the foraging behaviour of leaf-cutting ants, and decrease the productivity of this herbivore’s mutualistic fungal cultivar, Leucocoprinus gongylophorus. This negative effect of endophytes on the ant’s cultivar could be the result of direct fungalefungal interaction or indirect reductions in the quality of leaves,...
متن کاملNovel fungal disease in complex leaf-cutting ant societies
1. The leaf-cutting ants practise an advanced system of mycophagy where they grow a fungus as a food source. As a consequence of parasite threats to their crops, they have evolved a system of morphological, behavioural, and chemical defences, particularly against fungal pathogens (mycopathogens). 2. Specific fungal diseases of the leaf-cutting ants themselves have not been described, possibly b...
متن کاملMathematical modeling on obligate mutualism: Interactions between leaf-cutter ants and their fungus garden.
We propose a simple mathematical model by applying Michaelis-Menton equations of enzyme kinetics to study the mutualistic interaction between the leaf cutter ant and its fungus garden at the early stage of colony expansion. We derive sufficient conditions on the extinction and coexistence of these two species. In addition, we give a region of initial condition that leads to the extinction of tw...
