Title: 日本海堆積物に記録された過去の東アジア冬モンスーン変動 
(Reconstruction of east Asian winter monsoon in the past using sediment
archives in the Japan Sea)
Language: Japanese
Chair: 堀之内武（地球圏科学部門）

要旨

東アジアの気候は、夏の多雨と冬の厳寒で特徴づけられ、それぞれ東アジア夏モンスーン、冬モンスーンと呼ばれている。夏モンスーン期には、揚子江の流出に伴って塩分が低く栄養塩に富んだ東シナ海表層水が対馬海峡を通して日本海に流入し、日本海表層の成層と生物生産を維持している。また冬モンスーンによる日本海表層水の冷却は、海氷の生産と表層水の中深層への沈み込みによる換気をもたらしている。一方、日本海の海底堆積物への有機物の埋没フラックスは、生物生産と底層水酸化還元度に依存した有機物の分解とに制御されるので、夏モンスーンによる栄養塩に富む東シナ海沿岸水の日本海への張り出しと、冬モンスーンによる底層水の換気の程度のバランスで決まると考えられる。2013年に行われた統合深海掘削計画第346次調査航海（IODP Exp. 346）では、日本海の中で330 mから 3429 mにいたる様々な水深の7地点から連続な堆積物が掘削された。水深の最も浅いU1427地点を除くU1422-U1426およびU1430地点の堆積相は、千年スケールで繰り返す明暗互層をなす半遠洋性堆積物で、それらの明暗パターンは同時間面として広く対比でき、どのサイトの年代モデルも確立している。また日本海堆積物の明度は、有機炭素（TOC）含有量と強く逆相関することが分かっているので、堆積物写真、堆積物全体のガンマ線吸収率（GRA）からそれぞれ算出される明度、乾燥かさ密度を用いることで、各地点各時代のTOCフラックスを計算できる。そこで過去における冬モンスーンによる日本海中深層の換気パターンを復元するために、TOCフラックスの深度分布の時代変化を利用し、過去100万年間にわたる数万年スケールでの冬モンスーン変動の評価を試みる。

タイトル：有性生殖の進化生態学：性選択、繁殖干渉、群集構造

Evolutionary ecology of sexual reproduction: sexual selection, reproductive interference, and community structure

 

Daisuke Kyogoku (The Museum of Nature and Human Activities)

 

In sexually reproducing organisms, mating with individuals of the opposite sex is necessary to produce offspring. Mating process raises competition for mating opportunities among same-sex individuals (i.e. sexual selection) and the conflict of evolutionary interest between the sexes (sexual conflict), which drive the evolution of reproductive traits. Because reproductive traits can mediate interspecific interactions (e.g. reproductive interference), reproductive trait evolution can eventually influence the community structure. In this talk, I present three different studies that are related to the evolutionary ecology of sexual reproduction, and by doing so I discuss ways in which sexual reproduction is relevant to the origin and/or maintenance of biodiversity. First, I show a likely case of sexual conflict in a sexually reproducing dandelion, where the timing of flower closure is influenced by the identity of the pollen deposited on the stigma. Second, I present a case study of how reproductive trait evolution due to within-species sexual selection can mediate the strength of reproductive interference in a pair of seed beetle species. Third, I present a simulation model of secondary contact with genetically incompatible hybridization. This model suggests that habitat segregation can evolve without tradeoff in resource use ability and that habitat segregation is more likely to be found in nature than species recognition divergence, which has historically been more appreciated than habitat segregation in this context. I will also briefly present some of my ongoing projects and discuss future research plans.

 

有性生殖の進化生態学：性選択、繁殖干渉、群集構造

 

京極大助（兵庫県立人と自然の博物館）

 

有性生殖をする生物では、子孫を残すために異性個体との配偶が必要である。繁殖プロセスは、同性個体（特にオス）間の繁殖機会をめぐる競争（i.e. 性選択）やオスとメスの利害対立（性的対立）を生み出すことで、繁殖形質の進化を駆動する。またこうして進化した繁殖形質は繁殖干渉などの種間相互作用を介在するため、群集構造にも影響を与えると期待される。本発表ではこうした有性生殖にまつわる進化生態学的な話題を3つ提供し、全体として有性生殖が多様性の創出と維持にどのように関わっているのかを議論する。まず有性タンポポを例にオスとメスの利害対立の例と考えられる事例（花を閉じる時刻が受け入れた花粉の性質に影響される）を紹介する。続いて、種内の性選択により進化した繁殖形質がいかに繁殖干渉の強さに影響するかを昆虫のマメゾウムシ類で検証した例を紹介する。最後に、繁殖干渉によって資源利用能力のトレードオフ無しに棲み分けが進化しうること（さらには、棲み分けのほうが従来重視されてきた種認識の分化よりも進化しやすいと考えられること）を示した数理モデル研究を紹介する。発表では現在行っている研究についても簡単に紹介し、将来の展望についても議論したい。

List of possible research subjects (2022)

Title: Applications of InSAR and PolInSAR techniques to monitor forests biophysical parameters

Associate Professor: Ram Avtar

Forest cover almost one third of the earth’s surface and are recognized to have an impact on the global climate. Deforestation and forest degradation is one of the major causes of increase of greenhouse gases. Forests biophysical parameters (viz. height, structure, density and biomass) are essential for sustainable management. However, in-situ measurement of biophysical parameters are time and labour extensive. Therefore, the goal of the proposed research is to use advanced InSAR and PolInSAR techniques to monitor forests biophysical parameters. Successful candidate is required to have knowledge of geospatial data and tools to engage in relevant research.

 

Title: Impact of freshwater discharge along the Eurasian and North American continental margins on the ocean circulation in the North Pacific: present and past

Professor: Humio Mitsudera

This program deals with the meridional overturning in the North Pacific Ocean, which is controlled by Dense Shelf Water (DSW) formation in the Sea of Okhotsk. DSW entrains a lot of materials, such as dissolved oxygen, CO2 and iron, and carries them to the North Pacific through the intermediate layer of the ocean. The overturning intensity due to the DSW formation is determined by salinity along the northern coast of the Sea of Okhotsk. One of controlling factors is surface salinity anomaly originating in the North Pacific Ocean, which propagates into the Sea of Okhotsk via the Kuril Straits. Here, we propose to investigate the effects of freshwater discharges from the Eurasian and North American continents on the overturning circulation in the North Pacific. The riverine freshwater causes salinity anomaly along the continental margins, reaches the region of the DSW formation, and controls the overturning circulation efficiently. We pay attention not only to the effects of the freshwater discharge in the present days but also to those in the Last Glacier Maximum, during which rapid ice sheet discharge occurred around the Gulf of Alaska preceding the Heinrich events.

 

Title: Development of Photonic Superlattices of Semiconductor Quantum Dots

Professor: Vasudevan Pillai Biju

Novel semiconductor materials are necessary for next-generation energy efficient optoelectronic and photovoltaic applications. Such materials should be environment friendly and cost-effective. Also, characteristics such as efficient absorption of light, low exciton binding energy, minimal nonradiative carrier recombination, and defect-free structures are some of the pre-requisites of high quality semiconductors for optical and photovoltaic applications. Superlattices of such quantum dots offer many-fold opportunities to develop energy efficient photonic and photovoltaic devices. The purpose of this research is to develop novel non-toxic and low bandgap semiconductor quantum dots (QDs) and preparation of their superlattices for efficient utilization and harvesting of energy. A successful candidate is expected have a Masters Degree in Chemistry at the time of joining and he/she is required to have the knowledge of wet chemical reactions, and fundamentals of electronic spectroscopy.

 

English Program of Environmental Earth Science for a Sustainable Society (EPEES)

Introduction
Globalization has caused various environmental issues around the world that often transcend borders. In order to solve these problems, to conserve the earth’s precious environment for future generations and to build up a sustainable society, this program is intended to foster the development of professionals and researchers who can contribute to the protection of global and local environments based on extensive knowledge, global perspectives and the ability to act practically using their expertise. Graduates are expected to understand different cultures, customs and values, and to be able to cope with environmental problems in collaboration with researchers and experts from various countries. The program involves practical education in English through classes, work and seminars with the aim of seeking ways to maintain and enhance the sustainability of the earth’s system. Students adopt a main theme for their Master’s or Doctoral thesis under a supervisor, and simultaneously study a sub-research topic from a different field within a study group. This approach fosters the ability to judge international environmental problems appropriately on the basis of interdisciplinary focus.
