Article analysis:

The article provides a comprehensive overview of the influence of environmental factors on phytoplankton community structure and abundance in the Northern East China Sea (NECS). The authors have used correlation heatmaps and generalized additive models (GAMs) to explore the interannual variations in major phytoplankton groups and their relationships to environmental factors. The article also provides a detailed description of the sampling sites, water sampling methods, data analysis techniques, and results.

The article appears to be reliable as it provides evidence for its claims with references from previous studies. However, there are some potential biases that should be noted. For example, the authors have focused primarily on large phytoplankton groups such as diatoms and dinoflagellates which may not provide an accurate representation of all phytoplankton species present in the NECS. Additionally, while the authors have discussed potential impacts of climate change on phytoplankton communities, they do not provide any evidence or data to support this claim. Furthermore, while they discuss potential anthropogenic impacts on phytoplankton communities due to large hydraulic engineering construction such as Three Gorges Dam, they do not provide any information about how these impacts might manifest or what effects they might have on phytoplankton communities.

In conclusion, while this article provides a comprehensive overview of environmental influences on phytoplankton community structure in the NECS, there are some potential biases that should be noted when considering its trustworthiness and reliability.
