Bacterial protection of beetle-fungus mutualism.
Host-microbe symbioses play a critical role in the evolution of biological diversity and complexity. In a notably intricate system, southern pine beetles use symbiotic fungi to help overcome host-tree defenses and to provide nutrition for their larvae. We show that this beetle-fungal mutualism is chemically mediated by a bacterially produced polyunsaturated peroxide. The molecule's selective to...
متن کاملTrade-offs in an ant-plant-fungus mutualism.
Species engaged in multiple, simultaneous mutualisms are subject to trade-offs in their mutualistic investment if the traits involved in each interaction are overlapping, which can lead to conflicts and affect the longevity of these associations. We investigate this issue via a tripartite mutualism involving an ant plant, two competing ant species and a fungus the ants cultivate to build galler...
متن کاملRepeatability of Feather Mite Prevalence and Intensity in Passerine Birds
Understanding why host species differ so much in symbiont loads and how this depends on ecological host and symbiont traits is a major issue in the ecology of symbiosis. A first step in this inquiry is to know whether observed differences among host species are species-specific traits or more related with host-symbiont environmental conditions. Here we analysed the repeatability (R) of the inte...
متن کاملTwo new quill mite species (Prostigmata: Syringophilidae) parasitizing Australian birds.
Two new quill mite species (Prostigmata: Cheyletoidea: Syringophilidae), Syringophilopsis philemonis sp. nov. from Philemon citreogularis (Gould) (Passeriformes: Meliphagidae) and Megasyringophilus cacatua sp. nov. from Cacatua galerita (Latham) (Psittaciformes: Psittacidae) are described from Australia.
متن کاملExploiting a mutualism: parasite specialization on cultivars within the fungus-growing ant symbiosis.
Fungus-growing ants, their cultivated fungi and the cultivar-attacking parasite Escovopsis coevolve as a complex community. Higher-level phylogenetic congruence of the symbionts suggests specialized long-term associations of host-parasite clades but reveals little about parasite specificity at finer scales of species-species and genotype-genotype interactions. By coupling sequence and amplified...
