This isn't just a low quality paper. It is two paragraphs long. Its very last sentence is a sentence fragment. It just says "Rest may be important for train operators. Rest is also important for this particular kind of fly species."

I've seen low quality papers get published before, but they are enormously better than this. Even the very worst papers I've ever seen in peer review and given strong rejects to are enormously better than this. This wouldn't even cut it for a poster proposal at a conference.

I would expect a 6th grader writing a science report that they were given two weeks to complete to produce better writing than this.
