Chihiro Yoshimura 교수의 연구실은 강의 수문학적 특성과 유기물 순환 메커니즘을 중심으로 한 수생 생태계 연구를 수행합니다. 특히, 강의 급격한 유량 변화와 높은 유기물 분해 속도가 특징인 일본의 지형적 조건을 바탕으로, 미세 유기물(FPOM)의 화학적 성질과 미생물 호흡, 현장 분해 속도의 기초 메커니즘을 규명하고자 합니다. 연구는 주로 토양 및 식물 유래 유기물이 강의 생태계 기능에 미치는 영향을 분석하며, 특히 분해자인 갈색게(Gammarus spp.)를 활용한 실험적 접근이 특징입니다.

Abstract The Japanese Archipelago (land area: 377 880 km 2 ) extends over a distance of c . 2000 km, with a maximum width of 300 km. Geologically, it is a young and tectonically very active area. Japan is a mountainous, wet and forested country, with its people concentrated in densely populated urban areas along the coast and on alluvial plains. Rivers are short (max. length: 370 km), steep, and exhibit flashy flow regimes. The river regime coefficient ranges from 200 to 400, which is up to an o
Fine particulate organic matter (FPOM) plays a critical role in structuring and sustaining stream food webs by providing an essential resource for various organisms. Our goal was to elucidate FPOM dynamics by determining chemical properties, microbial respiration, and in situ decomposition rates of different FPOM fractions in relation to the parent coarse particulate organic matter (CPOM). FPOM (100–500 μm) of defined quality was produced by feeding 5 types of CPOM to shredding amphipods (<I&
