Interaction Between Climate Change Scenarios and Biological Invasion Reveals Complex Cascading Effects in Freshwater EcosystemsNARA Subscribed
Climate change often facilitates biological invasions, leading to potential interactive impacts of these global drivers on freshwater ecosystems. Although climatic mitigation efforts may reduce the magnitude of these interactive impacts, we are still missing experimental evidence for such effects under multiple climate change scenarios within a multi‐trophic framework. To address this knowledge gap, we experimentally compared...
Tracking long‐distance migration of marine fishes using compound‐specific stable isotope analysis of amino acidsNARA Subscribed
The long‐distance migrations by marine fishes are difficult to track by field observation. Here, we propose a new method to track such migrations using stable nitrogen isotopic composition at the base of the food web ( δ 15 N Base ), which can be estimated by using compound‐specific isotope analysis. δ 15 N Base exclusively reflects the δ 15 N of nitrate in the ocean at a regional scale and is not affected by the trophic posit...
Examining the impact of CITES listing of sharks and rays in Southeast Asian fisheriesNARA Subscribed
CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) aims to ensure that international trade in specimens of wild animals and plants does not threaten their survival. However, measuring the effectiveness and impacts of these trade regulations for commercially exploited aquatic species remains challenging. This study highlights observed or documented changes in elasmobranch fisheries in ei...
Spatial variations in time‐integrated plankton metabolic rates in Sagami Bay using triple oxygen isotopes and O2:Ar ratiosNARA Subscribed
Plankton metabolic rates, such as rates of gross, net community production and community respiration, were measured in the surface waters using triple oxygen isotopes and O 2 : Ar ratios. The 17D anomaly showed clear coastal and offshore gradients that were consistent with the distribution of chlorophyll a and oxygen saturation. Gross primary production (GPP) rates in coastal regions were several times higher than offshore reg...
