    The colonisation of land by plants may not have been possible without mycorrhizae, which supply the majority of land plants with nutrients, water and other benefits. In this sense, the mycorrhization of basal groups of land plants such as ferns and lycophytes is of particular interest, yet only about 9% of fern and lycophyte species have been sampled for their mycorrhization status, and no community-level analyses exist for tropical fern communities. In the present study, we screened 170 specimens of ferns and lycophytes from Malaysia and Sulawesi (Indonesia), representing 126 species, and report the mycorrhization status for 109 species and 19 genera for the first time. Mycorrhizal colonisations were detected in 96 (56.5%) of the specimens, 85 of which corresponded to arbuscular mycorrhizae (AMF), three to dark-septate endophytes (DSE) and four to mixed colonisations (AMF + DSE). DSE colonisations were lower than in comparable samples of ferns from the Andes, suggesting a geographical or taxonomic pattern in this type of colonisation. Epiphytes had significantly lower levels of colonisation (26.1%) than terrestrial plants (70.7%), probably due to the difficulty of establishment of mycorrhizal fungi in the canopy habitat.
  2. Fulltext Craspedotropis gretathunbergae, a new species of Cyclophoridae (Gastropoda: Caenogastropoda), discovered and described on a field course to Kuala Belalong rainforest, Brunei
    Schilthuizen M, Lim JP, van Peursen ADP, Alfano M, Jenging AB, Cicuzza D, et al.
    Biodivers Data J, 2020;8:e47484.
    PMID: 32132859 DOI: 10.3897/BDJ.8.e47484
    Background: Terrestrial Caenogastropoda form an important but threatened component of the Borneo tropical rainforest malacofauna, where the group is nearly as rich in species as the Stylommatophora. They are, however, more sensitive to drought, temperature extremes and forest degradation.

    New information: On a field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new caenogastropod species, belonging to the genus Craspedotropis, was discovered by the course participants. The participants decided to name the species Craspedotropis gretathunbergae n. sp., in honour of the climate change activist Greta Thunberg, as caenogastropod land snails, such as this species, are likely to suffer because of climate change.

  3. Fulltext A new species of Clavicornaltica (Coleoptera: Chrysomelidae), discovered and described on a field course to Kuala Belalong, Brunei
    Schilthuizen M, Berenyi AEA, Limin A, Brahim A, Cicuzza D, Eales AJ, et al.
    Biodivers Data J, 2019.
    PMID: 30740026 DOI: 10.3897/BDJ.7.e32555
    Background: Clavicornaltica is a genus of very small flea beetles living in the leaf litter layer of Asian forests, easily sampled with Winkler extraction. The genus is presumably very rich in species, but their taxonomy is hampered by their small size and morphological uniformity.

    New information: On a 'taxon expedition'-style field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new species, Clavicornaltica belalongensis n. sp., was discovered and taxonomically treated by the course participants. We also present the first DNA barcodes for the genus.
