This is an excellent paper on the value of urban centres as refuges for wildlife.

well, the target spawning-site to which the following study is focused is surely man-made

Thanks for everyone for the responses! I will check the material provided.

@Ladislav Miko: My work is focused on macroscopic invertebrates of lakes formed in gravel pits and until now find some - at least for me - interesting features about the wild life of my study area (e.g. community structure).

”macroscopic invertebrates”...

meaning zooplankton (copepods, cladocerans etc.)?

or other groups, too? (e.g. larvae of insect)

p.s. on the arid continental plateau around us there are several natural (and in many cases temporary) pools (having only few square meter surface and less than 50 cm depth) with rocky bottom (even if they are in a loess-dominated region) that are very good sites for studies on seasonal dinamics of (aquatic and semi-aquatic) fauna

These are benthic organisms, eg. mayfly, stonefly larvae, crustaceans, water bugs. The size of these creatures are >2mm. Zooplankton is considered to be microscopic.

The temporary pools are an interesting issue. It was the theme of my work for the Scientific Youth Conference ("TDK") last year.

Hi Peter, There is not one, but a series of papers investigating the role of different aspects of urban habitat for invertebrates, plants and vertebrates in the UK. The project's name is Biodiversity in Urban Gardens - BUGS. These papers were very important to me and I think they will give you lots of data to support your study. You can downloads the pdfs from here: http://www.bugs.group.shef.ac.uk/

And I have made a study of cultivated plants in a Brazilian city and compared it to a natural reference area to discuss the potential role of cultivated plants for urban biodiversity:

Well, I am finishing a paper on this subject. As son as I have it ready, I'll send it to yu via this page, unless you want to provide me with an address

Thank you! It will be okay to send it via this page! 

Hi Peter, the BUGs project (Biodiversity in Urban Gardens) evaluated this aspect in urban areas of England. You can download the pdfs from their website: http://www.bugs.group.shef.ac.uk/

I evaluated the lack of perception of value of native biodiversity in a tropical city here: http://www.sciencedirect.com/science/article/pii/S1618866714000090

All the best,

There is a nature reserve in the area of a barrage on the river Inn between Germany and Austria. There are a lot of publications about this area.

Prof. Josef H. Reichholf, knows a lot about this area.
