Abstract Background & aims. Tea tree (Melaleuca alternifolia) is an economically important crop plant with a limited natural distribution in eastern Australia. Coastal and upland tea ecotypes have been identified based on unique shoot root traits. Dual mycorrhization, the ability of plants to associate both arbuscular mycorrhizal (AM) ectomycorrhizal (ECM) fungi, particularly frequent among Australian Myrtaceae, including Melaleuca species. However, type currently unknown. Methods. We investigated associations three coastal two populations using ITS2 metabarcoding anatomical observations. Results. Our results revealed that dual showing variability symbioses populations. found ECM percentage colonisation was significantly lower compared populations, despite exhibiting higher levels fungal richness. In contrast, we showed moderate evidence AM richness than ecotypes, yet comparable were observed between ecotypes. Mycorrhizal community composition also differed plants. Conclusions. study provides dual-mycorrhizal species can host fungi simultaneously within individual findings suggest environmental factors sites, soil drainage nitrogen availability, affect traits native

Orchidaceae is one of the most species-rich families flowering plants, with current diversity having evolved within last 5 My. Patterns associated species richness and rapid diversification have been identified but not often evolutionary processes. We review frequently correlates suggest that processes rate by which they occur vary geographically are largely dependent on persistent pulses habitat instabilities, especially for epiphytes. Aggressive orogenesis creates fragmented habitats while global climatic cycles exacerbate ecological instabilities. The need repeated dispersal results in frequent founder events, sets stage allopatric via bouts genetic drift natural selection. allopatry requirement can be bypassed pollination systems involving flowers attracting pollinators through production sex signaling semiochemicals. drift-selection model diversification, coupled instability throughout geological time scales, likely components a multifactorial process leading to rapid, recent this family.

Societal Impact Statement Biological samples and their associated information are an essential resource used by scientists, governments, policymakers, practitioners communities to ensure that biodiversity can be appropriately protected sustainably used. Yet, considering the enormous task of documenting vast numbers as‐yet‐unknown plant fungal species, greater international coordination for biological collecting recording is necessary, built on equitable practices standards. Here, we propose five commitments accelerate enhance scientific knowledge diversity, while increasing collaboration, benefit sharing efficiency. Summary Almost all life depends plants fungi, making diversity distribution—primarily derived from collections—fundamental national conservation, restoration sustainable use commitments. However, it estimated some 15% species over 90% have not yet been scientifically described, hampering our ability assess demonstrate impact efforts halt loss. In addition, organisations researchers around world lack a concerted strategy complementarity avoiding overlap in botanical mycological research, particularly relation collection specimens. We here present 2030 Declaration Scientific Plant Fungal Collecting, summarising commitment towards such necessary strategy. Its components were identified discussions during after series four workshops plenary at 2023 State World's Plants Fungi symposium convened Royal Botanic Gardens, Kew, then consolidated into form authors. The was subsequently opened up endorsement signatories. Collectively, agree set cataloguing world's flora funga, designed maximise efficiency, facilitate exchange promote collaborations: (1) evidence‐based strategies; (2) strengthen local capacity; (3) collaborate across taxa disciplines; (4) collect future; (5) share benefits. This first step increased global regional efforts.

Sites were categorized (17-18-year-old plantations) three age classes (8-29, 30-55, 65-131-year-old stands). High-throughput sequencing applied samples investigate assemblages. Native forests showed higher ectomycorrhizal (EcM) OTU than plantations, regardless age.

Fungi are arguably the most diverse eukaryotic kingdom of organisms in terms number estimated species, trophic and life history strategies, their functions ecosystems. However, our knowledge fungi is limited due to a distributional bias; vast majority available data on have been compiled from non-tropical regions. Far less known about tropical regions, with bulk these being temporally surveys for fungal species diversity. Long-term studies (LTS), or repeated sampling same region over extended periods, necessary fully capture extent diversity region, but LTS regions almost non-existent. In this paper, we discuss contributions alpha diversity, ecological functional biogeography, hypothesis testing, conservation-with an emphasis ongoing Pakaraima Mountains Guyana. We show how refine understanding Fungi. also that public repositories such as NCBI, IUCN, iNaturalist contain information compared fungi, discrepancies more pronounced than plants animals.

Fairy Circles (FCs) are roughly circular, spatially periodic barren patches occurring both along the southwestern African coast, spanning Namib Desert (NFCs), and in Pilbara region of Western Australia (AFCs). The origin NFC AFC patterns is still debatable a subject ongoing research. Recently, it was argued that pathogenic soil microbes may contribute to ring formation Triodia basedowii grass which same species forms AFCs. We have analyzed, under controlled laboratory conditions, samples taken from different parts AFCs (center, periphery m3atrix) for microbiological activities by Lettuce germination experiments manipulations. In seven circles, out an average 13, root lengths germinated seeds were strongly inhibited center, lesser extent, matrix.
