“…Globally, fungi form an important component in the diet of a wide array of birds, mammals and reptiles (Fogel & Trappe 1978; Elliott et al . 2019a,b). After ingesting reproductive parts of fungal fruiting bodies, animals disperse, via their scats, viable fungal spores that can form mycorrhizal associations with plants (Trappe & Maser 1976; Reddell et al .…”

Thirty camera traps were deployed for a total of 4179 trap-nights between January and June 2020 as part of a project assessing post-fire recovery of pademelons (Thylogale spp.) in northern New South Wales. By chance, one camera documented a site that was highly productive for the ectomycorrhizal fungal genus Amanita. This camera provided a rare opportunity to document a diversity of co-habitating vertebrates that utilise these ectomycorrhizal fungi for food and in turn perform an important ecosystem function through the dispersal of their spores. Our camera recorded eleven vertebrate species; of these, we captured photographic evidence of Australian brush-turkeys (Alectura lathami), a parma wallaby (Notamacropus parma), long-nosed bandicoots (Perameles nasuta), red-legged pademelons (Thylogale stigmatica) and red-necked pademelons (T. thetis) feeding on fungal fruiting bodies.

“…They may even preferentially eat fungi. Previous dietary research on the species may have overlooked mycophagy since ornithological studies seldom use appropriate methodologies to detect fungal spores in scats or stomachs (Elliott & Vernes 2019;Elliott et al 2019a).…”

“…The role of wood‐decay fungi as precursors for cavity excavation was verified for several woodpecker species in temperate systems of North America and Europe (Elliott et al., 2019). Yet woodpecker–fungi interactions remain poorly known for most Picid species, especially those that inhabit the Neotropics, Africa and Asia.…”

Decay fungi associated with cavity excavation by a large South American woodpecker

In temperate systems of the Northern Hemisphere, wood‐decay fungi are known to facilitate cavity excavation by woodpeckers. For South America, woodpecker–fungi interactions have not been explored. The aim of this work was to identify wood‐decay fungi associated with the process of cavity excavation by the Magellanic woodpecker (Campephilus magellanicus), a large South American picid that excavates on living trees. The survey was conducted in old‐growth Nothofagus pumilio forests of Patagonia. For freshly excavated cavities, wood condition was assessed, adjacent basidiocarps were collected, and fungal cultures were obtained from wood samples taken to the laboratory. All cavities exhibited softened wood. Four Agaricomycotina were isolated in cultures: Stereum hirsutum was the most frequent, followed by Postia pelliculosa, Nothophellinus andinopatagonicus and Aurantiporus albidus. Basidiocarps around cavities were of two species that did not develop in cultures: Laetiporus portentosus and Macrohyporia dictyopora. Excavations were slightly more frequent in white rot colonized than brown rot colonized wood, but this may be an artefact of differential success in fungal isolation and culturing, since several cavities that showed visual symptoms of brown wood rots did not yield mycelia of those wood‐decay fungi. As shown by research elsewhere, basidiocarps underestimated heart rot on cavity walls and revealed additional wood‐decay species living on the same trees; therefore, assessments of fungal diversity in substrates used for cavity excavation should be based on culturing and/or DNA extraction. Because fungal communities in the southern Andes are poorly known, decay fungi and their roles in ecosystem development should be studied across different forest areas, where samples from non‐cavity‐bearing (control) trees should also be taken in order to determine excavation‐site selection.

“…These dispersal mechanisms are diverse and ecologically complex, which makes them challenging to measure or predict; this in turn limits the predictive capacity of dispersal models, almost all of which have been developed for seeds of plants (Aslan et al., 2019). The role of animals in fungal spore dispersal is similarly complex and ecologically important but has been far less thoroughly studied (Elliott, Bower, et al., 2019; Elliott, Jusino, et al., 2019; Fogel & Trappe, 1978; Tuno, 1998; Vašutová et al., 2019).…”

“…The spores of truffle‐like fungi tend to be deposited in situ (Miller et al., 1994) or transported short distances by invertebrates (Houston & Bougher, 2010; Lilleskov & Bruns, 2005; Reddell & Spain, 1991). For LDD to occur, however, vertebrate vectors such as mammals, birds, or reptiles are needed (Cooper & Vernes, 2011; Elliott, Bower, et al., 2019; Elliott, Jusino, et al., 2019; Fogel & Trappe, 1978; Luoma et al., 2003). Animal vectors of spore dispersal (particularly those traversing habitat boundaries) are crucial to assisting truffle‐like fungi in the colonization of associated plants in naturally patchy habitats, modified landscapes or “new” habitats such as glacial forefronts (Cázares & Trappe, 1994), beaver meadows (Terwilliger & Pastor, 1999), and stabilizing sand dunes (Ashkannejhad & Horton, 2005).…”

Animal movement patterns play a role in animal-mediated ecological processes, including propagule dispersal. Mechanisms of propagule dispersal have been widely studied, particularly among plants (Levin et al., 2003). These dispersal mechanisms are diverse and ecologically complex, which makes them challenging to measure or predict; this in turn limits the predictive capacity of dispersal models, almost all of which have been developed for seeds of plants (Aslan et al., 2019). The role of animals in fungal spore dispersal is similarly complex and ecologically important but has been far less thoroughly studied (
