Background. Aims and Scope Lakes developing in volcano craters can become highly acidic through the influx of volcanic gases, yielding one of the chemically most extreme natural environments on earth. The Kawah Ijen crater lake in East Java (Indonesia) has a pH 〈 0.3. It is the source of the extremely acid and metal-polluted river Banyupahit (45 km). The lake has a significant impact on the river ecosystem as well as on a densely populated area downstream, where agricultural fields are… 

Leaf Decomposition in an Extremely Acidic River of Volcanic Origin in Indonesia

Functional processes in freshwater ecosystems are highly influenced by acidic conditions. Foodwebs are affected and macroinvertebrate species diversity is decreased. This study aims to investigate

Rivers and Lakes: Acidification

The pH values of most natural, river, and lake waters are in the range of 6–9. There are natural and anthropogenic sources that may influence the acidification of surface inland waters. The former

Microbial Communities in the World's Largest Acidic Volcanic Lake, Kawah Ijen in Indonesia, and in the Banyupahit River Originating from It

The acidity gradient of the Banyupahit–Banyuputih river has a clear effect on microbial community composition and biodiversity, and tolerance to extreme acidity in this system is developed most extensively among Archaea.

A tale of two lakes: the Newberry Volcano twin crater lakes, Oregon, USA

Abstract Newberry Volcano in Oregon, USA, has two small crater lakes inside its caldera: East Lake and Paulina Lake. The 50–80 m deep lakes differ in morphology, water chemistry and sediment

Findings indicate that species tolerant of low pH (i.e., <4.5) are not confined to humic waters as has been postulated, but also occur in soft, non-humic waters where concentrations of labile,non-organically bound aluminium may be elevated.
