Oecologia, 01 Sep. 2022, [Reviewed] - Microbial mutualism promoting the coexistence of competing species: Double-layer model for two competing hosts and one microbial species.
Yokoi H; Takeuchi Y; Ichinose G; Kitade O; Tainaka K., Gause's law of competitive exclusion holds that the coexistence of competing species is extremely unlikely when niches are not differentiated. This law is supported by many mathematical studies, yet the coexistence of competing species is nearly ubiquitous in real ecosystems. We pay attention to the fact that plants and animals usually contact with microbial species as mutualistic partners. The activity spaces of host species are different from those of micro-organisms. In the present study, we apply double-layer model to the association of two competing hosts and a microorganism. Two lattices are prepared: one is for hosts, and the other is for microorganism. The basic equation obtained by mean-field theory is an extension of Lotka-Volterra competition model. Both mathematical analysis and numerical simulations reveal that a shared microbial mutualist can permit the coexistence of competing hosts. From the derived condition of coexistence, we believe the microbial mutualism promotes biodiversity in many ecological systems., Elsevier

Kitade; O. and Hayashi; Y., Lead, The distributional range of Reticulitermes kanmonensis, a termite species so far recorded only in and around Shimonoseki, Japan, was investigated. On the Honshu side of the Kanmon Strait where Shimonoseki is located, R. kanmonensis has a wider distributional range than has been thought; colonies were found not only in areas along the coast, but also in inland areas including forests with natural vegetation. In Kyushu the termite was found only in and around the Kiku Peninsula. The distributional patterns of R. kanmonensis and related species and the historical background of the distributional area strongly suggest the artificial introduction of this species into Shimonoseki., Entomological Society of Japan

SOCIOBIOLOGY, 2001, [Reviewed] - A reexamination of the taxonomic position of Chinese Heterotermes aculabialis (Isoptera : Rhinotermitidae) based on the mitochondrial cytochrome oxydase II gene.
Xing; L.; Maekawa; K.; Miura; T.; Kitade; O. and Matsumoto; T., Although Heterotermes has been thought to be confined to tropical areas, some Chinese taxonomists suggest that this genus is also distributed in subtropical to temperate areas and treat some Chinese species as Heterotermes. We sequenced 677 bp of the mitochondrial COII gene of several Reticulitermes and Heterotermes species from Australia, France, China, Indonesia and Japan. The inferred molecular phylogeny showed that Heterotermes aculabialis from China and Reticulitermes species from various localities of the world formed a monophyletic group, suggesting that the Chinese Heterotermes aculabialis should be transferred to Reticulitermes. Our preliminary findings of the flagellate fauna in the hindgut of this species support this suggestion., Entomological Society of Japan

Molecular Phylogenetics and Evdution., 1999 - Phylogenetic comparison of endosymbionts with their host ants based on molecular evidence.
Sameshima; S.; Hasegawa; E.; Kitade; O.; Minaka; N. and Matsumoto; T., Some Formicid ants have symbiotic intracellular bacteria in the epithelial cells of their midgut. These endosymbionts are believed to be derived from a common ancestor. A recent study revealed that endosymbionts of the ant genus Camponotus are closely related to Enterobacteriaceae, but their relationship to endosymbionts of other genera of ants is unknown. In this study, the nucleotide sequences of 16S ribosomal RNA (rRNA) of endosymbionts and mitochondrial cytochrome oxidase subunit I (COl) of their host were determined in five genera of the subfamily Formicinae (Hymenoptera: Formicidae). Based on these molecular data, we constructed phylogenetic trees in order to characterize the systematic position of the symbionts and to estimate the relationship of symbionts and hosts. The analysis showed that the endosymbionts were all connected with the Enterobacteriaceae but did not constitute a monophylitic group, while the three genera belonging to the tribe Camponotini, the endosymbionts and their hosts made a clade. The topologies of these trees were identical for the most part. These results suggest that the endosymbionts of ants have plural origins, and that in the Camponotini, ancestral symbionts have coevolved with their host ants, which are so divergent to several genera as to construct one tribe., Zoological Society of Japan

Maeyama; T.; Kitade; O. and Matsumoto; T., There are many ccological studies of ants. occupying the myrmecophytes. in relation to the infractions between hosts and symbionts. However, the other occupants of myrmecophytes have been scarcely studicd. It is very important to investigate all the occupants and arboreal fauna to clarify their symbiotic relationships. Wc surveyed the complete occupant fauna inhabiting the epiphytic myrmecophytes, Hydnophytum moseleyanum in mangrove forests in Papua New Guinea. A diverse fauna was revealed, that was composed of 11 ant species and 39 spceies of other animal groups. Almost all the occupant species would be comrnensals facultatively utilizing the space inside the myrmecophytcs for their inhabitation. The existence of the epiphytic myrmecophyteg. should play a significant role for the maintenance of arboreal biodiversity because myrmecophytes provide the shelters and moisture for arboreal animals and markedly increase potential sites for their dwelling., JAPAN SOCIETY OF TROPICAL ECOLOGY
