AB - We examined the expansion of Amanita muscaria into native protected Nothofagaceae forests of Patagonian Argentina and documented its occurrence in pure stands of Nothofagus dombeyi and Lophozonia alpina. We confirmed the ectomycorrhizal association between A. muscaria and L. alpina root tips, representing the first verified record of this symbiosis in Patagonia. We provided detailed morphological descriptions of the ectomycorrhizas formed with N. dombeyi and L. alpina and compared them with those formed with the most planted Pinus spp. These descriptions revealed diagnostic traits that allowed us to reliably distinguish the new associations from previously known A. muscaria morphotypes. Our results support the use of ectomycorrhizal morphotyping as a low-cost and practical tool for monitoring invaded stands and for evaluating the impact and effectiveness of forest management interventions across these native forests.

AB - Several tree-killing bark beetle species have nutritional mutualisms with specific fungi. However, few secondary bark beetles (those that colonize weak or dying trees) have been investigated for symbiotic fungi and most are thought to have only incidental fungal associates and no dependence on fungi for nutritional or other benefits. In contrast to this supposition, we consistently isolated (> 97%) a fungus from adult Ips confusus (pinyon ips) collected from Pinus edulis (two-needle pinyon pine) from Arizona and New Mexico, USA. Using morphology and DNA sequences for three gene regions, we found the fungus is most closely related to an obligate mutualist fungus of Dendroctonus ponderosae (mountain pine beetle), Ophiostoma montium (Ascomycota: Ophiostomatales), but is morphologically and genetically distinct from it and other known species in Ophiostoma. It is also capable of growth at relatively high temperatures compared with other Ophiostoma, reflective of its southwestern USA distribution. The high frequency of its association with the beetle indicates it is symbiotic and suggests it may be a mutualist. LA - English DB - MTMT ER - TY - JOUR AU - Kutty, M. Sangeeta AU - Jyothymol, C. P.

AB - Bark beetles are fundamental drivers of forest ecosystem dynamics. However, some species within this group have recently also emerged as significant pests in environments managed by humans, including nurseries, orchards, and urban areas. Specifically, certain Scolytus species pose potential economic and ecological threats to stone fruit cultivation across the Mediterranean basin. Although the role of the mycobiome in mediating bark beetle-host interactions has been well documented for many forest models, the symbiotic associations between beetles and fungi in cultivated Mediterranean agroecosystems remain poorly understood. This study provides the first comprehensive characterization of the fungal community associated with the almond bark beetle Scolytus amygdali in southern Mediterranean almond orchards. Integrating culture-dependent isolations with culture-independent approaches, i.e., high-throughput sequencing, allowed us to assess the beetle mycobiome across beetle adults, gallery systems, and associated necrotic wood lesions. Molecular characterization revealed Geosmithia, Paecilomyces, and Quambalaria to be the dominant taxa within the S. amygdali mycobiome. Their frequent occurrence suggests that they may be recurrent associates in the gallery environment, although their functional roles remain unclear. Furthermore, metabarcoding analyses provided additional novel insights into the beetle mycobiome, identifying Candida and Yamadazyma yeasts as potential core constituents of the gut microbiome. Future research should prioritize elucidating the role of these putative fungal symbionts for the beetles, particularly the pathogenic potential on almonds, and the functional efficiency of S. amygdali as a vector. Overall, our findings elucidate the complex taxonomic diversity of these associations. Moreover, obtained results provide a foundational ecological framework to better understand to what extent these associations can threaten host plants and to develop future sustainable management strategies in managed ecosystems.
