lake acidification

It is not simply fish species which have suffered from lake acidification.

However, this is the only duck in North America known to derive short-term benefits from lake acidification.

But the agency said, "The report data suggests that chronic regional lake acidification has not occurred in the mountainous areas of the West."

Very long-term records of lake acidification can provide quite dramatic evidence for the recent accentuation of the acid deposition problem.

It is generally accepted that increasing lake acidification due to acid deposition has caused fish kills and stock depletion (figure 4.14).

Consequences of climate warming and lake acidification for UV-b penetration in North American boreal lakes.

Topics include: lake acidification caused by acid rain, sewage input and fertilizer runoff (eutrophication); studies of contaminant transport; and a large program on climatic change.

Though not the single source of lake acidification, it appears even the heavily industrialized Ohio Valley has contributed to the ecological problem of lakes as far north as northern Ontario.

As concern has grown over lake acidification in diverse parts of Europe and North America during the last 20 years, the influence of changes in land use has become a prominent part of the debate.

Lake acidification studies in the Experimental Lake Area (ELA) in northwestern Ontario clearly demonstrated the negative effects of increased acidity on a native fish species: lake trout (Salvelinus namaycush) recruitment and growth dramatically decreased due to extirpation of its key prey species during acidification.
