Two major volatiles produced by the mycelia and fruiting bodies of Tricholoma matsutake (1-octen-3-ol and methyl cinnamate) repel a mycophagous collembolan, Proisotoma minuta. Aggregation of the collembolans on their diet was significantly inhibited by exposure to 1 ppm methyl cinnamate or 10 to 100 ppm 1-octen-3-ol. The aggregation activity decreased(More)
Dileptid and tracheliid ciliates have been traditionally classified within the subclass Haptoria of the class Litostomatea. However, their phylogenetic position among haptorians has been controversial and indicated that they may play a key role in understanding litostomatean evolution. In order to reconstruct the evolutionary history of dileptids and(More)
Ciliates play important roles as prey and predators in ecosystems. Changes in the ciliate community can affect the composition and population of microfauna and microflora in ecosystems. To investigate the structure of ciliate communities, we developed a nested PCR-DGGE method, which combines a universal eukaryotic-specific primer set in the first PCR step(More)
To minimize the degradation of soil organic matter (SOM) content in conventional sugarcane cropping, it is important to understand how the fungal community contributes to SOM dynamics during the decomposition of sugarcane leaf litter. However, our knowledge of fungal diversity in tropical agroecosystems is currently limited. Thus, we determined the fungal(More)
This study examined the effect of conversion from a conventional tillage (CT) to a no-tillage (NT) practice and of bagasse mulching (M) on soil microbial community composition and potential functions, using phospholipid fatty acid (PLFA) analysis and shotgun metagenome sequencing. Our results showed that both the NT and the M treatment increased microbial(More)
This article discusses a business-school collaborative learning partnership in the Regional Centre of Expertise (RCE) on Education for Sustainable Development (ESD) in Greater Sendai. This partnership is further linked to a broader context of multi-stakeholder public participation in the RCE that was set up to advance the ESD agenda in the region. The(More)
The first detailed description of adults of Achipteria setulosa Golosova, 1981 with illustrations are provided, based on materials from central Japan. This species is placed in the subgenus Achipteria (Izuachipteria) Balogh & Mahunka, 1979. In addition, the species grouping of the known species in the genus Achipteria is briefly discussed, and three(More)
The morphology of adult instars of two oribatid mites of the genus Neoribates, N. pallidus Aoki, 1988 and N. alius Fujikawa, 2007, is analyzed. Comparisons were based on holotype and paratypes (for N. alius) and specimens identified by the original author (for N. pallidus). Both species were described from Japan. Neoribates alius is recognized as a junior(More)
Ophiocordyceps sessilis, a new species of Ophiocordycipitaceae, Hypocreales, was found on Camponotus obscuripes ants, where the ants were primarily infected by another close relative, O. pulvinata. Morphological observation clearly indicated that O. sessilis and O. pulvinata are distinct species. Ophiocordyceps sessilis exhibited superficial development of(More)
