However, the diversity and dynamics of ambrosia beetles, other wood-boring insects, and their fungi remain relatively poorly understood in the forests of temperate South America. Baseline knowledge of insect and fungal diversity is therefore needed to provide a foundation for understanding the potential future dynamics of these critically important ecosystems in the context of global change. This study aimed to document fungal diversity that could be obtained in culture from larvae, adults, and galleries of ambrosia beetles (<i>Gnathotrupes</i> spp.) and a carpenter moth (<i>Chilecomadia valdiviana</i>) from lenga (<i>Nothofagus pumilio</i>) in northwest Patagonia, Argentina. Long molecular barcodes from fungal cultures isolated from galleries, larvae, and adult insects were obtained using nanopore sequencing. Fungal assemblages associated with <i>Gnathotrupes</i> spp. (32 unique taxa) and <i>C. valdiviana</i> (17 unique taxa) differed in structure and composition but shared 11 distinct taxa. Differences were found between fungal assemblages associated with <i>C. valdiviana</i> gut tracts and galleries. Fungal assemblages found in galleries and insect bodies of <i>Gnathotrupes</i> varied among species, seasons, and health conditions of the host crown. Our results also showed that the ophiostomatoid fungi <i>Raffaelea</i> spp. and yeast <i>Cyberlindnera</i> sp. were commonly found with <i>Gnathotrupes</i> spp. whereas <i>Ambrosiozyma angophorae</i> and <i>Oidiodendron</i> sp. were found with <i>C. valdiviana</i>.

The ability of lichens to synthesize melanins is an important adaptation in response to adverse light conditions, including ultraviolet (UV) irradiation and high light. Previously, we demonstrated that melanization of the lichen <i>Lobaria pulmonaria</i> is accompanied by the accumulation of melanin granules in the upper cortex. However, very little information is available on the morphology and physicochemical properties of these particles. Here, for the first time, we used polyclonal antibodies against eumelanin to visualize melanin in the upper cortex of <i>L. pulmonaria</i> and confirm its identity. Using scanning electron microscopy, we showed that extracted melanins are large, spherical aggregates, with an average size of 230 nm. The aggregates had an irregular and unstable structure and displayed high adhesive properties, according to atomic force microscopy. Purification using size exclusion chromatography showed that melanins coeluted with polysaccharides. Purified particles were visualized as discrete structures (subaggregates) with an average size of 42 nm and displayed higher stability and lower adhesive properties than non-purified aggregates. In colloidal aqueous systems, melanin particles formed aggregates with particle sizes of 279 and 212 nm for the non-purified and purified samples, respectively, suggesting that the removal of the polysaccharide component during purification causes the condensation of the polyaromatic structure of melanin. Taken together, our results suggest that melanin particles extracted from UV-melanized thalli of the lichen <i>L. pulmonaria</i> comprise a supramolecular assembly of melanin and polysaccharides. Analysis of the size, ζ-potential, and polydispersity index suggests that melanin particles are capable of structural rearrangements that lead to changes in their nanomechanical properties.
