User:Chikyra/Evaluate an Article

Which article are you evaluating?
Freshwater ecosystem

Why you have chosen this article to evaluate?
To begin, I wanted to do just aquatic ecosystems in general, but I then chose freshwater ecosystems because I felt like I had better knowledge on its definition to perform a better evaluation. I also feel like it would be a heavily trafficked page due to its relevance to many introduction-level biology and ecology courses, so I thought it would be an important page to review.

Evaluate the article
In the lead section, while there is a reference at the end of it, I found one sentence rather obscure and lacking substance, which was "Freshwater ecosystems have undergone substantial transformations over time, which has impacted various characteristics of the ecosystems." Perhaps it could be stronger if the author explained what kinds of changes, such as geological changes, or evolutionary changes in organisms, etc. Furthermore, it could be worth having a section about the dynamism of freshwater ecosystems and the cycles which underpin them, such as the hydrogeological cycle and their subjectivity to seasonality. Furthermore, the article has no images. I would include a diagram of the multiple types of freshwater ecosystems, or perhaps their percentage of freshwater in general on Earth to give more perspective in the lead section.

The thing that struck me the most (which I also found in a comment from 2018 on the talk page) is that the sections include threats and extinction, yet no mention of key characteristics, or ecological factors. Besides the lead section, there is nothing about the distribution, occurrence, ecology or biology of freshwater ecosystems. It takes an entirely social approach, which should be included, but not comprise the entirety of the page. I think most pressing is that multiple sections need to be added to this page.
