Journal ArticleDOI
Determination of aquatic food-web structure based on compound-specific nitrogen isotopic composition of amino acids
Yoshito Chikaraishi,Nanako O. Ogawa,Yuichiro Kashiyama,Yoshinori Takano,Hisami Suga,Akiko Tomitani,Hideaki Miyashita,Hiroshi Kitazato,Naohiko Ohkouchi +8 more
TL;DR: This study investigated the δ15N signatures of amino acids in 17 photoautotrophs and the trophic relationships during four controlled feeding experiments using green algae, zooplankton, and fish, implying that the amino acid method can be applied to a variety of organisms.
Journal ArticleDOI
Paleoenvironmental Changes in the Japan Sea During the Last 85,000 Years
TL;DR: In this paper, five distinct changes in the paleoenvironment of the Japan Sea within the last 85,000 years are revealed from the sedimentary record of a piston core recovered from the Oki Ridge.
Journal ArticleDOI
Foraminifera promote calcification by elevating their intracellular pH
TL;DR: The results show that ongoing ocean acidification can result in a decrease of calcite production by these abundant calcifyers, suggesting that elevating the pH at the site of calcification is a widespread strategy among foraminifera to promote calcite precipitation.
Journal ArticleDOI
Metabolic control of nitrogen isotope composition of amino acids in macroalgae and gastropods: implications for aquatic food web studies
TL;DR: It is suggested here that metabolic fate is an impor- tant factor in producing distinct trophic relationships in nitrogen isotopic compositions between amino acids.
Journal ArticleDOI
High rates of microbial carbon turnover in sediments in the deepest oceanic trench on Earth
Ronnie N. Glud,Ronnie N. Glud,Frank Wenzhöfer,Frank Wenzhöfer,Mathias Middelboe,Kazumasa Oguri,Robert Turnewitsch,Donald E. Canfield,Hiroshi Kitazato +8 more
TL;DR: In this article, the authors used an autonomous micro-profiling system to assess benthic oxygen consumption rates at Challenger Deep in the Mariana Trench in the central west Pacific, which at almost 11,000m depth represents the deepest oceanic site on Earth.
