“…There are many reasons for the disappearance of some species, abiotic ones such as toxic concentrations of hydrogen ions or other chemicals, or biotic ones such as changes in feeding conditions, competition or predation relations (Eriksson et al, 1980;Nilssen et aL, 1984).…”

The hydroseral development of a former small lake in Southern Finland was studied by means of subfossil cladoceran remains, diatoms, pollen, plant macrofossils and other sediment data. The diatom analysis shows the lake to have become markedly acid during the Early Holocene. This is reflected in the cladoceran communities in the form of a fall in the proportions of Bosmina longirostris etc. and a reciprocal rise in Bosmina (Eubosmina) longispina, an increase in the proportions of the chydorid species indicative of acidity, and the appearance of certain new morphotypes. The concentrations of both planktonic and littoral species and the numbers of such species increase with acidification. Advancement in the hydroseral succession is reflected in the disappearance of benthic species from the chydorid communities and a pronounced increase in exclusively phytophile species. Sedimentation and the drop in water levels are seen to have led to a spread of helophytes and floating-leaved plants over the water body around 6500-7000 B.P., and a vegetation-filled swamp was created at the site. The zooplankton was practically exterminated, but the concentrations of littoral cladocerans reached their peak at this point. The basin became overgrown completely at the beginning of the Subboreal chronozone (approx. 4600-4800 B.P.), simultaneously with the low-water phase observed in many lakes. It became covered with a Sphagnum stand, and this in turn led to complete destruction of the cladoceran communities. The planktonic/littoral ratio among the Cladocera closely reflected the relation between open water and the macrophyte zone as a function of time. Climatically induced rises and falls in water level are shown to have played a significant role in promoting the advancement of the hydroseral succession.

“…2) sure from fish has resulted in abundant populations of pelagic insects (e.g. Eriksson et al, 1980;Henrikson & Oscarson, 1981, 1985Nilssen et al, 1984), and food does not, initially, limit the recovery growth of a perch population after liming (e.g. Eriksson et al, 1983).…”

Gill net catches of perch Percafluviatilis in eight acidified lakes immediately before liming are compared with catches in the same lakes two years after liming. Simultaneously, six control lakes, not limed, were investigated with the same procedures. A significant increase in the average'catches of perch was found in the limed lakes, but not in the control lakes. This result confirms earlier reports, although seldom supported with data from controls, on successful recovery after liming.

“…Species substitutions within cladocerans during acidification are fairly well known (Roff & Kwiatkowski 1977;Nilssen 1980Nilssen , 1984Nilssen et al 1984;Hobaek & Raddum 1980;Yan & Strus 1980;UimonenSimola & Tolonen 1987;Marmorek & Korman 1993), but their quantitative spatial and temporal distribution, ecology, and life histories during acidification are less well known. Such and similar types of information are available from non-acidic sites (Lynch 1980;Kankaala 1983;Hessen & Schartau 1988;Lampert 2001;Sarma et al 2005; and references in all).…”

“…The dominant Daphnia species in the present geographical area comprise D. lacustris and D. longispina (Nilssen 1980(Nilssen , 1984Nilssen et al 2007). It has been known for many decades that D. longispina is physiologically sensitive to low pH, like the rest of the species within the genus (Skadovsky 1926;Nilssen et al 1984;Brett 1989). The two former species generally decrease strongly at pH below 5.0-5.5 (Nilssen 1980;Nilssen & Waervågen 2002b;Bērziņš & Bertilsson 1990).…”
