abstract:
Two ponds were studied in the Echo pond complex – one large and one small. A total of 3011 water mite specimens belonging to 44 species were collected. The fauna of the large pond was much more abundant – 2956 specimens belonging to 40 species were collected, while 55 specimens from 12 species were collected from the small pond. Lake forms clearly predominated in the large pond, while in the small pond crenophile and rheophile species were found. The differences in the fauna of the two ponds indicate that hydrotechnical restructuring involving elimination of smaller water bodies will contribute to a decrease in Hydrachnidia biodiversity.
