The authors describe five new species of Pristionchus from Japan and Hongkong. Scarab beetle samplings in Hongkong identified P. hongkongensis sp. n. and P. neolucani sp. n., representing the first beetle-associated Pristionchus species from China. Surprisingly, samplings of millipedes in Japan revealed a previously unknown association of Pristionchus nematodes with these arthropods. Specifically, the authors found three previously known Pristionchus species, P. arcanus, P. entomophagus, and P

. was isolated from Holotricha sp. (Coleoptera: Melolonthinae) in Japan and belongs to the lheritieri-species-complex. P. paulseni sp. n. was isolated from Taiwan and represents the gonochoristic sister species of P. fissidentatus. This species exhibits a mouth dimorphism found in many Pristionchus species, suggesting that mouth-form plasticity is an ancestral character in the genus. Most importantly, P. paulseni sp. n. and P. fissidentatus form a new species group of the genus that represents the

zones (PB63S, PBo6S, PxS, P234, P112 – Poland; PB7’96, PB8 – Japan, PUSAS – the USA) of P. ostreatus were analyzed. All strains were shared by the Department of Fruit, Vegetable and Mushroom Technology at the University of Life Sciences in Lublin. According to our knowledge, the strains analyzed were never cultivated on media containing antibiotics. Before experiments the fungal strains were cultivated for seven days in 28°C on Petri dishes with onion medium (onion extract 1000 ml (150 g of chopped

Millipedes may cause unexpected damage when they are introduced to new locations, becoming invaders that leave behind their old parasites and predators. Therefore, it was interesting to find numerous rhabditid nematodes within the gut of the invasive phytophagous millipede Chamberlinius hualienensis Wang, 1956 (Diplopoda, Paradoxosomatidae) from Hachijojima (Japan) in November, 2014. This millipede originated in Taiwan but was discovered in Japan in 1986. The nematodes were identified as

Mitogenomic diversity and genetic population structure of the pinewood nematode (PWN) Bursaphelenchus xylophilus inhabiting Kyushu, Japan were analyzed. A method for performing long PCR using single nematodes and sequencing nematode mitochondrial genomes individually is presented here. About 8 kb (∼55%) of the complete mitochondrial genome was successfully obtained from 285 individuals collected from 12 populations. The 158 single nucleotide polymorphisms detected corresponded to 30 haplotypes

Xiphinema parachambersi n. sp. recovered in Ningbo, China, from the rhizosphere of ornamental plants (Gardenia jasminoides and Euonymus hamiltonianus) imported from Japan is described. The new species is characterized by a long female body 1,830 to 2,109 μm long, odontostyle 105 to 116 μm long, reproductive system mono-opisthodelphic, vulva located anteriorly at 25.2 to 27.7% of total body, long ovary 119 to 292 μm with simple uterus and Z-organ absent, female tail elongated conoid with a

Sugarcane (Saccharum spp. hybrids) is an economically important crop in subtropical and tropical regions. Okinawa is located in the subtropical region in Japan and half of its farmland acreage is used for sugarcane cultivation. Many remote islands in Okinawa are economically reliant on sugarcane-related industries.
Plant-parasitic nematodes are one of the major yield limiting factors of sugarcane production (Cadet and Spaull, 2005). Previous studies revealed that 20 to 30% sugarcane yield

), parthenogenesis may have evolved twice independently in these two genera. Consequently, the genome for a Halicephalobus species may reveal illuminating parallelisms in how asexuality influences genomic evolution.
Here, we have sequenced the genome of a Halicephalobus strain (NKZ332) isolated from termites in Japan. Because of the paucity of reliable diagnostic morphology for the genus (Anderson et al., 1998), combined with the inability to test species boundaries through crossing experiments, assignment of a

One of the most popular flowers in Japan is chrysanthemum (Chrysanthemum morifolium Ramat.), that is used on ornamental purposes in many occasions especially for new year’s and religious ceremonies, and even recognized as an edible plant in Japan. The total production of chrysanthemum in Japan in 2016 was 68bn yen (ca. $620m), which consisted one-third of the total cut-flower production and was the number one product of all the cut-flower categories (Statistics by the Japanese Ministry of

This study investigated the experiences of men and women with vision disabilities knowing about and participating in information programs provided by guide dog organisations; and investigated the way information programs affect people’s perceptions and attitudes towards guide dogs in Japan where people are hesitant to acquire a guide dog. The results suggest that the information programs had been widely publicised and were familiar to participants. Younger women were the most experienced

containment building and the cooling of the core meltdown in the reactor. Confirming the progressive state of diagnosis and the cooling of the reactor core when the serious accident occurs is a very important factor in the development of response strategies after the accident. Japan has taken various measures to deal with accidents after the nuclear accident of Fukushima. Strengthening the reliability of the instrumentation system is also included in the counterstrategies. Therefore, this paper presents

At the same time, huge alterations in the within-country mortality rankings can be observed. Australia, Japan, Taiwan, Austria and Luxembourg may be said to be the “winners” while most of the post-communist countries are among the “losers”.

Xiphinema japonicum n. sp., isolated in Ningbo, China, from the rhizosphere of Podocarpus macrophyllus (Thunb.) imported from Japan is described. The new species belongs to Xiphinema non-americanum group 7 and is characterized by medium body length (3.0–3.7 mm), total stylet length 190–201 μm, vulva located anteriorly (V = 30.5%–35.3%), two equally developed female genital branches without uterine differentiation (no Z or pseudo-Z organ and/or spines in the uteri), short tail, convex-conoid

Asia has emerged as a hotspot of Pristionchus speciation and recent samplings have therefore focused on Islands and mainland settings in East Asia. Here, we describe in a series of three publications the results of our sampling efforts in Taiwan, Japan, and Hongkong in 2016 and 2017. We describe a total of nine new species that cover different phylogenetic species-complexes of the Pristionchus genus. In this first publication, we describe two new species, Pristionchus sikae sp. n. and Pristionchus

segregation is important because it creates gender stereotypes and strengthens traditional gender roles. Second, it prevents people from understanding each gender and makes romantic relationships more complex. Third, interactions of both genders enhance the social capital of women.
