ABSTRACT Nanoplanktonic diatoms (2–20 μm) are a significant yet historically understudied component of marine ecosystems. We investigated three recently isolated nanoplanktonic diatoms from the Northwest Atlantic Ocean (NWA): Minidiscus spinulatus, Mediolabrus comicus, and Minidiscus trioculatus.

ABSTRACT Nitrofuran metabolites, including semicarbazide, pose significant risks to food safety, particularly in the aquatic industry. Bangladesh's shrimp industry faced major challenges due to nitrofuran contamination, leading to a voluntary export suspension to the European Union (EU).

Direct Evidence of Nutrient Upwelling and Phytoplankton Enhancement at a Continental Shelf Break
Abstract A long‐standing hypothesis postulates that the elevated productivity at continental shelf break regions is stimulated by enhanced nutrient supply to the surface sunlit depths, however, direct, quantitative evidence has been lacking. We tested this hypothesis with a set of high‐resolution physical and biogeochemical observations from repeated ...

Abstract This study simulates circulation patterns in Lake Tanganyika, an economically vital lake in East and Central Africa that has experienced significant warming, and reduced fishery yields in recent decades. We use Regional Ocean Modeling System to analyze thermal stratification, wind‐driven processes, and circulation dynamics within the lake. Our

Over the last 70 years, seabird populations have declined by up to 70% across the globe. Compared to other seabirds, little is known about Snow Petrels and their marine habitat use—especially in East Antarctica. This study addresses the former knowledge gap while simultaneously comparing how outputs differ when data collection methods vary.

The deep‐pelagic fish community showed differences in functional strategies along the depth gradient. Epipelagic species exhibited significant trait convergence with traits adapted to the prey‐tracking strategy, while bathypelagic species exhibited significantly higher functional richness values than expected at random.

New Approaches to Assess Food Web Stability in Aquatic Ecosystems: A Case Study on Baiyangdian Lake
A method for calculating the interaction strength of a phytoplankton‐based and a detritus food web. A geometric mean ratio of predator‐to‐prey biomass BCBPt$$ {\left(\frac{B_C}{B_P}\right)}_t $$ as an alternative indicator for food web stability. The changes in the stability of the BYD Lake from the 1950s to the 2010s indicate that two steady‐state ...

Hypothesis‐Driven Research on Multiple Stressors: An Analytical Framework for Stressor Interactions
Multiple‐stressor research is relevant across ecological sub‐disciplines (terrestrial, marine, and freshwater), aiming to predict how anthropogenic stressors combine. Different null models have been developed for this purpose. Here, we introduce an analytical framework to statistically evaluate any a priori chosen null model to facilitate hypothesis ...
