Insights into Ontogenetic Niche Changes in Bluegill, Lepomis macrochirus, Applying Combined Analyses of Stomach Content and Stable Isotopes

Autor: Yeong-Ho Kwak, Seung-Yong Kim, Young-Shin Go, Dong-Hun Lee, Ha-Yun Song, Sang Ok Chung, Jeong Bae Kim, Bohyung Choi

Publikováno v: Water, Vol 15, Iss 19, p 3488 (2023)

We integrated stomach content analysis (SCA) and stable isotope analysis (SIA) to understand ontogenetic niche shifts in the invasive freshwater fish, bluegill, Lepomis macrochirus, inhabiting the Yedang Reservoir in Korea. Based on the total length

Microbial alteration in marine sediments: Insights from compound-specific isotopic compositions of amino acids in subseafloor environments

Autor: Hyuntae Choi, Bohyung Choi, Yoshito Chikaraishi, Yoshinori Takano, Haryun Kim, Kitack Lee, Dhongil Lim, Kyung-Hoon Shin

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

The proportion of amino acids (AAs) in sediment can be used as an indicator of microbial degradation, which is primarily the product of benthic prokaryote activity. The microbial activity would be reflected with the stable isotope ratio of nitrogen (

Amino acid nitrogen and carbon isotope data: Potential and implications for ecological studies

Autor: Hee Young Yun, Thomas Larsen, Bohyung Choi, Eun‐Ji Won, Kyung‐Hoon Shin

Publikováno v: Ecology and Evolution, Vol 12, Iss 6, Pp n/a-n/a (2022)

Abstract Explaining food web dynamics, stability, and functioning depend substantially on understanding of feeding relations within a community. Bulk stable isotope ratios (SIRs) in natural abundance are well‐established tools to express direct and

A new insight into isotopic fractionation associated with decarboxylation in organisms: implications for amino acid isotope approaches in biogeoscience

Autor: Yuko Takizawa, Yoshinori Takano, Bohyung Choi, Prarthana S. Dharampal, Shawn A. Steffan, Nanako O. Ogawa, Naohiko Ohkouchi, Yoshito Chikaraishi

Publikováno v: Progress in Earth and Planetary Science, Vol 7, Iss 1, Pp 1-13 (2020)

Abstract Stable nitrogen (15N/14N) and carbon (13C/12C) isotopic compositions of amino acids in organisms have widely been employed as a powerful tool to evaluate resource utilization and trophic connection among organisms in diverse ecosystems. Howe

Trophic response to ecological conditions of habitats: Evidence from trophic variability of freshwater fish

Autor: Bohyung Choi, Changhwa Lee, Yuko Takizawa, Yoshito Chikaraishi, Hye‐Ji Oh, Kwang‐Hyeon Chang, Min‐Ho Jang, Hyun‐Woo Kim, Kyung‐Lak Lee, Kyung‐Hoon Shin

Publikováno v: Ecology and Evolution, Vol 10, Iss 14, Pp 7250-7260 (2020)

Abstract To adapt to ecological and environmental conditions, species can change their ecological niche (e.g., interactions among species) and function (e.g., prey‐predation, diet competition, and habitat segregation) at the species and guild level
