Little is known about microbial communities of aquatic plants despite their crucial ecosystem function in aquatic ecosystems. Here, we analyzed the microbiota of an aquatic rheophyte, Hanseniella heterophylla, growing at three areas differing in their degree of anthropogenic disturbance in Thailand employing a metabarcoding approach. Our results sh...

Human activity negatively affects the sustainability of forest ecosystems globally. Disturbed forests may or may not recover by themselves in a certain period of time. However, it is still unclear as to what parameters can be used to reasonably predict the potential for self-recovery of human-disturbed forests. Here, we combined seed rain, soil see...

Podostemaceae show different patterns of morphological variation relative to molecular ones between genera and between species, but additional material was necessary to make the patterns clearer. Using new material collected from Cambodia, we compared the variations of Terniopsis chanthaburiensis and T. heterostaminata in Cambodia, Laos and Thailan...

In this paper, based on recent collections, we add three species of Podostemaceae to the flora of Thailand. First, Cladopus pierrei was newly recorded from Sa Kaeo Province, southeastern Thailand. Phylogenetic analysis showed that C. pierrei is a paraphyletic species, in which plants from Thailand have a sister relationship with C. doianus. The num...

In order to understand the evolution of the body plan characteristic of the unique aquatic Podostemaceae, seedlings of crustose-rooted species of the Hydrobryum clade, i.e., Hanseniella heterophylla, Hydrobryum loeicum, Hy. tardhuangense, Hy. vientianense and Thawatchaia trilobata, were studied by sectioning and scanning electron microscopy. In all...

... The average value of percent functional assignment of FUNGuild is 43% (ranging from 38-46%). These values are consistent with the percentage points of functional assignment of FUNGuild reported before in many publications [39,46,47]. Nevertheless, it is known that the percentage points of functional assignments of taxonomically dependent functional annotation tool highly depends on the quality and quantity of the database backbone of each sequence data, taxonomic identification and functional description [48]. ...
... X capability of roots, which is essential for the haptophytic life, although other differences are not excluded. In other areas, too, foliose species of Hydrobryum are sympatric with ribbon-like species of Cladopus in, e.g., two waterfalls in Khao Yai National Park, central Thailand; a waterfall in Sa Kaeo, eastern Thailand; and two rapids in Kagoshima, Japan (Kato 2004(Kato , 2006(Kato , 2008Koi and Kato 2012;Werukamkul et al. 2018;Kato unpubl. observations). ...
... H. heterophylla is one of the rheophyte species in which the developing root became lobed and produced additional tufts of leaves in its more distal part. The leaf is filiform with thin dense hairs on the ventral side; by this mechanism, they adapt themselves to the rock surface and extreme water current (Koi et al., 2012). Similar to other plant species in Podostemaceae, H. heterophylla develop so-called adhesive hairs on its undersurface. ...
