Which article are you evaluating?

[edit]

Signal crayfish

Why you have chosen this article to evaluate?

[edit]

I chose this article as it seems a similar invasive species to the one that I would like to write about, the Northern Ringed Crayfish. I am hoping to learn some details about items that I may try to replicate and steer away from when writing my own Wikipedia article.

Evaluate the article

[edit]

Lead Section:

[edit]

The lead section begins with a very brief sentence on the signal crayfish, that may benefit from one other additional fact. There is a general description of the passages that follow (Description and ecology, Native range, and Introduction into Europe). The lead section is concise and only touches upon matter that is already present throughout the rest of the article.

Content:

[edit]

The content listed for the signal crayfish is up-to-date, and stays on topic with relevant information about this species.

Tone and Balance:

[edit]

The article is neutral while describing the disruptive effects of the introduction of this species to Europe, and how it has spread the crayfish plague to native European crayfish species. Much of the article touches upon the damaging effects of the signal crayfish, and the article may benefit from further details on its life in its native habitat.

Sources and References:

[edit]

There are a total of 18 sources listed for this article, and 9 are from 2010 to present. Many appear to be scientific peer-reviewed articles. Some are data sheets from the U.S. fish and wildlife service, and personal blogs. A reviewer may want to go through the references for this article to help determine factual basis.

Organization and Writing Quality:

[edit]

The article is clear, but sometimes feels like the narrative "jumps". This could be due to only wanting to include data about the signal crayfish, and removing any filler details. Grammar is almost entirely free of errors, but it would benefit from further editing.

Images and Media:

[edit]

There are three images in this article that all assist in providing a sense of what the signal crayfish looks like and any distinguishing characteristics.

Talk Page Discussion:

[edit]

The talk page has one comment and I agree with what is said:

This page needs some info on the actual natural history of this crayfish - although internationally known for it's introduction elsewhere, it does have behaviour and distribution in it's own right which should be listed here. Kert01 12:10, 10 August 2006 (UTC)

This page is a member of WikiProject Arthropods.

Overall Impressions:

[edit]

I feel that this article would benefit from greater details about the species in its native habitat, as well as other distinguishing behaviors (besides having been a progenitor of crayfish plague in Europe). I also feel that some of the language and sentence structure could be improved upon to enhance readability.
