Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

On the horizontal distribution of algal-bloom in Chaohu lake and its formation process

, 2014
 Based on the remote sensing images of algae, the present work analyzes the horizontal distribution characteristics of algal blooms in Chaohu Lake, China, which also reveals the frequency of algal blooms under different wind directions.

A Comparative Analysis of Machine Learning Methods for Algal Bloom Detection Using Remote Sensing Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Algal blooms are a major environmental challenge for lakes and reservoirs and pose severe threats to water on both aquatic and human health. Conventional algorithms used for algal bloom detection based on remote sensing reflectance proved to be effective

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Surface primary producer phenology in Dease Strait, NU, Canada, examined using submersed oceanographic sensors and satellite remote sensing

Arctic Science
Thinning sea ice cover and earlier melt in the Arctic impact primary producer (PP) phenology, causing earlier ice algal bloom termination and phytoplankton bloom commencement.

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

Limnology 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 ...

Harmful Algal Blooms

, 2023
Harmful algal blooms (HABs) in marine, brackish, and fresh-water environments are caused by a variety of microscopic algae and cyanobacteria. HABs are hazardous and sometimes fatal to human and animal populations, either through toxicity, or by creating ecological conditions, such as oxygen depletion, which can kill fish and other economically or ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

A novel algal bloom risk assessment framework by integrating environmental factors based on explainable machine learning

Ecological Informatics
In recent years, the algal blooms have intensified, posing mounting threats to aquatic ecosystems and water security. However, most previous studies merely detected algal blooms according to the characteristics of the water body at the time of algal ...

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

Oikos, EarlyView.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context
