Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Soil-plant mercury concentrations in the Idrijca river terraces (Slovenia)

Geologija, 2004
The subjects of research are mercury contents in plants and soils on river terraces in the lower reaches of the Idrijca River. Samples of averaged meadow forage and plaintain (Plantago lanceolata) contain from 0.055 to 0.220 mg Hg/kg in dry matter.

A Macroinvertebrate‐Based Flow Index Elucidates Responses to Environmental Water in a Highly Regulated River

River Research and Applications, EarlyView.
ABSTRACT Macroinvertebrate‐based flow indices have potential application to guiding environmental flow allocations and monitoring their effectiveness, but their sensitivity to such flows has seldom been tested. We examined the response of the Australian Macroinvertebrate Flow Index (AMFI), calculated from family‐level data, to three stages of ...

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

River Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

River Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.
