No full textNotes on Marchantiaceae taxa in East Asia With the publication of novel and regionally recorded taxa, the Marchantiaceae in East Asia is represented by three well-recognized genera (Zheng & Shimamura 2022a), including 14 taxa (Bischler-Causse 1989; Long & Crandall-Stotler 2020; Xiang et al. 2016, 2022; Zheng & Shimamura 2020, 2022a, 2022b; Zheng & Long, 2023). Among them, some taxa doubtfully recorded in the Chinese bryoflora (Marchantia emarginata subsp. emarginata and M. stoloniscyphulus (Gao & Chang 1982: 114) Piippo 1990: 134) warrant a brief discussion in this study. Marchantia emarginata subsp. emarginata was first reported by Chao (1943, as “ M. palmata Nees ”) and subsequently recorded in some regional studies (Jia & He 2013; Xiong & Cao 2018) in China. However, Zheng (unpublished) found that (1) subgeneric classification of the M. emarginata complex is geographical rather than morphological, (2) there is excessive morphological diversity within the specimens identified as subsp. emarginata by the original author and (3) the distinguishing character of this subspecies (e.g., epidermal papillae and narrower appendages of ventral median scales) are not easily observed in some Southeast Asian specimens, indicating that the present treatments and morphological definition of subsp. emarginata are not tenable and need to be further reviewed. For M. stoloniscyphulus, Zheng et al. (unpublished) have been able to show that it is conspecific with M. papillata Raddi (1822: 20) subsp. grossibarba (Stephani 1894b: 221) Bischler (1989: 78) rather than being an independent species. Therefore, both taxa should be excluded from the following key.Published as part of Zheng, Tian-Xiong, Long, David G. & Shimamura, Masaki, 2023, Range extension of Marchantia formosana (Marchantiaceae, Marchantiophyta), with an updated key to Marchantiaceae taxa in East Asia, pp. 93-98 in Phytotaxa 612 (1) on page 96, DOI: 10.11646/phytotaxa.612.1.8, http://zenodo.org/record/830890

Spatial patterns of water properties in Mizoro-ga-ike pond
No full text湿地において，人為起源の養分の流入は湿地の富栄養化やそれに伴う生物多様性の減少を引き起こす。京都市北区にある深泥池は，多様な生物が生息・生育する池である。池の中央部には浮島がある。この池は1950-60年代に，水道水や下水などが流入し富栄養化が進行したが、その後に行われた水質対策は必ずしも十分ではなかった。現在の深泥池の水質分布特性を調べ，池の水質の現状評価を行った。その結果，池の北側を走る道路からの汚水，特に冬場の凍結防止剤に使用されるCaCl2や，池南東部にある松ヶ崎浄水場からの水道水が，現在の富栄養化を進行させる要因となっていた。また，ヨシやマコモなどの抽水植物がこれらの汚水の流入地点付近で繁茂し，栄養塩を除去し，開水面などで稀少な保護対象植物の生育が可能となっている事が示唆された。Artificial nutrient loading has been linked to decrease in plant diversity in peatlands, riparian areas and swamps. Mizoro-ga-ike pond in Kyoto City is one of the natural monuments of Japan bearing temperate floating mat and diverse plant community. The pond had experienced eutrophication by sewage and tap-water in 1960-70s. As the inflows of nutrient rich water had been lessened, amount of source area of the pond decreased to 30 %. We investigated factors that control water chemistry in and around the pond to assess the present situation of the pond.湿地において，人為起源の養分の流入は湿地の富栄養化やそれに伴う生物多様性の減少を引き起こす。京都市北区にある深泥池は，多様な生物が生息・生育する池である。池の中央部には浮島がある。この池は1950-60年代に，水道水や下水などが流入し富栄養化が進行したが、その後に行われた水質対策は必ずしも十分ではなかった。現在の深泥池の水質分布特性を調べ，池の水質の現状評価を行った。その結果，池の北側を走る道路からの汚水，特に冬場の凍結防止剤に使用されるCaCl2や，池南東部にある松ヶ崎浄水場からの水道水が，現在の富栄養化を進行させる要因となっていた。また，ヨシやマコモなどの抽水植物がこれらの汚水の流入地点付近で繁茂し，栄養塩を除去し，開水面などで稀少な保護対象植物の生育が可能となっている事が示唆された。Artificial nutrient loading has been linked to decrease in plant diversity in peatlands, riparian areas and swamps.

Water and Energy Balance of the Mizoro-ga-ike Pond
No full text京都市の深泥池には，高層湿原の浮島が存在し，動植物の希少種が豊富であるためその生物群集全体が天然記念物に指定されている。しかし，集水域の開発による涵養水減少や富栄養化の進行が保全上の問題となっている。深泥池にとっての健全な水環境を維持するためには，現在の深泥池の水・熱循環を知るとともに集水域面積や植生様式が変化した場合の水・物質収支を予測する必要がある。そこで本研究では，深泥池の富栄養化過程を伴う植生様式の変化を航空写真の画像解析によって明らかにした上で，浮島や抽水植物の植生別面積を考慮した水・熱循環の特性を現地観測によって明らかにした。その結果，浮島の存在が水温変動を緩和する効果を有していることが明らかとなった。これは，浮島が1年を通しての浮沈運動に伴って熱容量を変化させる，という性質を有することに起因すると考えられた。また，池からの蒸発散量が植生割合の変化に伴って変化することが分かった。その結果，過去と比較して現在は，池からの蒸発散量が減少している可能性があることが示された。To clarify and quantify the energy and water balance of Mizoro-ga-ike Pond, observation system for collecting micrometeorological elements and related hydrological elements has been set up from the beginning of 2005. Comparing the mean daily water temperature, the range of annual fluctuation(max-min) was 18.5℃ at floating island and was 23℃ at open water. This difference shows a thermal insulation effect of floating island which can mild the temperature of the pond. In addition, so that the floating island moves ups and downs through the year, heat capacity changes at each month. It is clarified that water and the heat circulation of Mizoro-ga-ike Pond have uniqueness because of the existence of the floating island. In addition, so that the floating island moves ups and downs through the year, heat capacity changes at each month. Moreover, it has been understood that there is a possibility that the amount of the evaporation decreases.京都市の深泥池には，高層湿原の浮島が存在し，動植物の希少種が豊富であるためその生物群集全体が天然記念物に指定されている。しかし，集水域の開発による涵養水減少や富栄養化の進行が保全上の問題となっている。深泥池にとっての健全な水環境を維持するためには，現在の深泥池の水・熱循環を知るとともに集水域面積や植生様式が変化した場合の水・物質収支を予測する必要がある。そこで本研究では，深泥池の富栄養化過程を伴う植生様式の変化を航空写真の画像解析によって明らかにした上で，浮島や抽水植物の植生別面積を考慮した水・熱循環の特性を現地観測によって明らかにした。その結果，浮島の存在が水温変動を緩和する効果を有していることが明らかとなった。これは，浮島が1年を通しての浮沈運動に伴って熱容量を変化させる，という性質を有することに起因すると考えられた。また，池からの蒸発散量が植生割合の変化に伴って変化することが分かった。その結果，過去と比較して現在は，池からの蒸発散量が減少している可能性があることが示された。To clarify and quantify the energy and water balance of Mizoro-ga-ike Pond, observation system for collecting micrometeorological elements and related hydrological elements has been set up from the beginning of 2005.

Rescue of Metabolic Alterations in AR113Q Skeletal Muscle by Peripheral Androgen Receptor Gene Silencing
No full textSummarySpinal and bulbar muscular atrophy (SBMA), a progressive degenerative disorder, is caused by a CAG/glutamine expansion in the androgen receptor (polyQ AR). Recent studies demonstrate that skeletal muscle is an important site of toxicity that contributes to the SBMA phenotype. Here, we sought to identify critical pathways altered in muscle that underlie disease manifestations in AR113Q mice. This led to the unanticipated identification of gene expression changes affecting regulators of carbohydrate metabolism, similar to those triggered by denervation. AR113Q muscle exhibits diminished glycolysis, altered mitochondria, and an impaired response to exercise. Strikingly, the expression of genes regulating muscle energy metabolism is rescued following peripheral polyQ AR gene silencing by antisense oligonucleotides (ASO), a therapeutic strategy that alleviates disease. Our data establish the occurrence of a metabolic imbalance in SBMA muscle triggered by peripheral expression of the polyQ AR and indicate that alterations in energy utilization contribute to non-neuronal disease manifestations
Letter from residents requesting prisoner release, February 18, 1944
No full textLetter from residents requesting the release of two incarerees: Wataru Obara, and Hiroichi Shimamura, detained in army stockades at Tule Lake Camp.The Willard Schmidt collection, documents some of the administrative duties of Willard Schmidt, the Chief of Internal Security for the War Relocation Authority and the Tule Lake incarceration/segregation camp. This collection contains administrative records and photos documenting the Tule Lake camp, the largest incarceration camp with a peak population of 18,789 and with the most turbulent history. In 1943, the camp was turned into a segregation center to house "disloyal" Japanese Americans relocated from other camps based on their answers to a confusing loyalty questionnaire. The camp endured martial law from November 1943- Jan 1944 after escalating protests and unrest. The hostile environment of the camp lead to many incarcerees renouncing their American citizenship upon the end of incarceration, a process which took 14 years to reverse if they did not wish to be deported to Japan
