A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Seagrass species diversity in Tanzania based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Numerical simulation of tidal bore based on CFD method

open access: yesShuili Shuiyun Gongcheng Xuebao, 2019
The tidal bore is a kind of nonlinear strong discontinuous flow that has great impact on wading structures. The small-scale fine simulation of the tidal bore is the premise for analyzing the structural stability of the wading structures under tidal ...

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

open access: yesOikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Impact of Coastal Squeeze Induced by Erosion and Land Reclamation on Salt Marsh Wetlands

open access: yesJournal of Marine Science and Engineering
Salt marshes are declining due to the dual pressures of coastal erosion and land reclamation. However, there remains a lack of quantitative analysis regarding this reduction process and its driving mechanisms.

Characterising fine‐scale habitat associations for range expanding species with limited data: a case study on the West Nile Virus vector, Culex modestus

open access: yesOikos, EarlyView.
The ecological and epidemiological consequences of species expanding into new areas are growing concomitantly with climate change. Those aiming to monitor species expanding in range must make optimal use of finite resources to deliver effective surveillance capable of detecting new incursions and range expansions.

Spatiotemporal dynamics and influencing factors of native and invasive saltmarshes in a rapidly silting bay during 1985–2023

open access: yesFrontiers in Marine Science
Globally, native saltmarshes are declining, while invasive saltmarshes are expanding rapidly. However, the underlying processes and driving mechanisms behind these trends remain poorly understood, particularly in rapidly silting coastal bays.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...
