Ostracods as ecological and isotopic indicators of lake water salinity changes: the Lake Van example

Paleoecological response of ostracods to early Late Pleistocene lake-level changes in Lake Malawi, East Africa

a r t i c l e i n f o Keywords: Lake Malawi Ostracoda Lake levels Climate change Ostracod species from at least seven genera were recovered from drill cores recently collected at Lake Malawi, a large (29,500 km 2) and deep (706 m) African rift valley lake located in the southern African tropics (9–14° S). Allocypria? and an unknown Cypridosine. Taphonomic variables such as the percentage of val...

Isotopic paleolimnology of Lake Kinneret

The carbonate, organic C, and N contents and their respective d13C were measured in four cores from Lake Kinneret, Israel. Using these data and the isotopic difference between coexisting carbonate and organic C, Dd13C, we attempted to reconstruct the lake’s productivity and regional climatic conditions during the late Holocene. The sedimentary record of the last 120 yr (for which climatological...

Urmia Lake desiccation and the signs of local climate changes

The water crisis is one of the important issues in the Middle East countries. Many lakes are ‎drying up and/or facing critical situations, exerting tremendous impacts on the socio-economics ‎of their region. Lake Urmia, in northwestern Iran, currently is facing critical situations and is on ‎the brink of total ‎shrinkage and environmental disaster. This paper investigates the roots of crises ‎t...

Morphological and Ecological Differences Between Shallow- and Deep-water Lake Trout in Lake Mistassini, Quebec

Lake trout (Salvelinus namaycush) in Lake Mistassini, Quebec, were investigated to determine whether they resembled the lean and siscowet morphotypes of Lake Superior and Great Slave Lake. Lake trout caught in deep water were predicted to resemble the siscowet morphotype and to be better adapted for vertical migration (i.e., low percent buoyancy) than those caught in shallow water. The research...
