متن کاملIsotopic 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...
متن کاملWalleye and Northern Pike
Introductions of nonnative walleye (Stizostedion vitreum) and northern pike (Esox lucius) have created popular recreational fisheries in many Northwestern waters. Rising demand for expanded angling opportunities for these species, especially walleye, has been met with growing concern about longterm risks associated with the introduction of a top predator. Proposed introductions are often contro...
متن کاملEditorial: Using Paleolimnology for Lake Restoration and Management
Paleolimnology has been used for decades to reconstruct past environments and more recently, to quantify the observed changes. Various organisms preserve in sediment of lakes and wetlands and can be used to reconstruct how a water body and the surrounding landscape looked like and has changed through time. For example, pollen, charcoal, and macrofossils can be used to reconstruct vegetation and...
