Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

Limnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Highly mobile pelagic species co‐occur with fine‐scale ocean fronts

Limnology and Oceanography, EarlyView.
Abstract Coastal areas are an important source of food and a valuable tourism asset for communities, but also highly dynamic and heterogeneous environments. Understanding how marine species respond to the variability of their habitat is essential to sustainably manage coastal resources.

Pre‐existing phytoplankton biomass concentrations shape coastal plankton response to fire‐generated ash leachate

Limnology and Oceanography, EarlyView.
Abstract Climate‐driven warming is projected to intensify wildfires, increasing their frequency and severity globally. Wildfires are an increasingly significant source of atmospheric deposition, delivering nutrients, organic matter, and trace metals to coastal and open ocean waters.

Concurrent global change and marine heatwaves disturb phototrophic more than heterotrophic protist diversity

Limnology and Oceanography Letters, EarlyView.
Abstract Anthropogenic pressures like ocean warming, acidification, rising N : P ratios, and marine heatwaves (MHWs) are affecting eukaryotic plankton diversity, though their combined impacts are rarely studied. To address this, we conducted a mesocosm experiment on a North Sea plankton community, testing the influence of a MHW under ambient and future

MARS: Programmable multipurpose auto‐release system for aquatic observations

Limnology and Oceanography: Methods, EarlyView.
Abstract Aquatic biodiversity assessments are often labor‐intensive due to the large size of the equipment and the complex logistics of sea vessel operations. Traditional drift and drop cameras are typically tethered to the surface, causing cable and line clutter on sea vessels.

Monitoring Euplotes species dynamics in mixed experiments using genetic markers for quantitative polymerase chain reaction

Limnology and Oceanography: Methods, EarlyView.
Abstract Ciliates are widespread and play a major role in ecosystems as they form an important link between primary producers and higher trophic levels. They have been used as a classic model to study predator–prey interactions of co‐evolutionary processes.

Calibration of the transparency tube for estimating turbidity in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Turbidity, quantified in turbidity units (nephelometric or formazin), is a common and valid measure of water quality related to transparency. A transparency tube (TT) is an economical tool developed to estimate water clarity as an alternative to the Secchi disk, but it is also frequently used to estimate turbidity.

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Stability and Hopf Bifurcations Analysis in a Three‐Phase Dengue Diffusion Model With Time Delay in Fractional Derivative and Laplace–Adomian Decomposition Numerical Approach

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the complex dynamics of dengue transmission by incorporating time delay into a comprehensive model. The model is designed to capture several essential components, including steady‐state events, immune waning, recuperation from infection, and partial shielding in human populations.
