Evaluate the drafted changes
 Lead 

The lead has been updated and starts off with a good introductory sentence that defines biological dispersal. The article draft is undergoing changes, so the brief brief description of major sections is not included as of yet. It would be beneficial to return to the lead section after having organized the article into major sections and add information about them. There is information added towards the end of the lead that briefly touches upon limitations faced by biological dispersal in certain environments like an urban environment. The addition is well placed, and the removal of the main articles last few sentences serves to make it concise overall.

Content
The content that is added is relevant to the topic and is up-to-date. In the draft following the lead the draft goes directly into a section titled 'Urban Environments' followed by 'Consequences of Dispersal,' I found the location of the two sections immediately after the lead to be a bit confusing. I would recommend retaining and editing the section titled 'Types of Dispersal' from the original article before introducing newer sections as it builds up to the broader applications of the concept. The content used is relevant but could benefit from citation to sources that provide evidence regarding the claims being made, like the patterns of biological dispersion in urban environments or the section discussing transfer of zebra mussels or Chinese bighead silver carp. The missing source citations seem to be found mainly in the 'Urban Environments' and 'Consequences of Dispersal' sections whereas the lead and the beginning of the 'observational Methods' provide citations as evidence to reinforce the statements.

Sources and References

There is information that is used without being backed up by a reliable source of secondary information in the two sections immediately after the lead. The content does reflect what the cited sources say accurately, however the missing sources in those two sections would benefit greatly from secondary source because without them it would just appear to be broad statements made without any proof. The sources are thorough, they are mostly papers that have been published within the last few years, the oldest publication was published nearly 20 years ago. Overall, the references are well chosen, published by different authors, and most are recently printed.

Organization
The content that has been added is well written, especially the addition to the lead and the beginning of the 'Observational Methods.' The other two sections being drafted currently provide valuable information but do so in a way that blends one occurrence with the next without providing sufficient relevant context to the detriment of the value of the statements. It is advised to rephrase and perhaps add more detail along with primary or secondary sources in the sections currently titles 'Urban Environments' and 'Consequences of Dispersal.'

Images and Media
There has been no additional changes to the images and media of the original article. It is recommended that a few more images be added within relevant context to allow for not only visual purposes but to show the overview of certain information or patterns.
