Topography of Teeth:Smithsonian Scientist Strengthens Tools To Track Animal,Ecosystem Responses to Major Environmental Changes
Topography of Teeth Smithsonian Scientist Strengthens Tools Track Animal Ecosystem Responses Environmental Changes
2016/11/29
By charting the slopes and crags on animals’ teeth as if they were mountain ranges, scientists at the Smithsonian’s National Museum of Natural History have created a powerful new way to lear...

Holocene Climate and Environmental Changes Disentangling Natural Anthropogenic Signals Sedimentary Record of Lake Lilandsvatnet
2014/10/21
This thesis presents a multi-proxy paleoenvironmental reconstruction from the sedimentary archives of Lilandsvatnet, a small arctic lake on Vestvågøy, in the Lofoten Islands, Norway. Lofoten...
The Expression of Leptin, Estrogen Receptors, and Vitellogenin mRNAs in Migrating Female Chum Salmon, Oncorhynchus keta: The Effects of Hypo-osmotic Environmental Changes
Chum Salmon Estrogen Receptors Leptin Maturation Salinity Change Vitellogenin
2016/5/16
Leptin plays an important role in energy homeostasis and reproductive function in fish, especially in reproduction. Migrating fish, such as salmonoids, are affected by external environmental factors, ...

The study area is located in the Pampean Plain (C髍doba, Argentina), where the groundwater resources of major interest are confined deep aquifers, which are often used due to the poor quality of the sh...
Foraminiferal response to environmental changes in Kiel Fjord, SW Baltic Sea
Foraminiferal response environmental changes Kiel Fjord, SW Baltic Sea
2010/9/28
The living benthic foraminiferal assemblages in Kiel Fjord (SW Baltic Sea) were investigated in the years 2005 and 2006. The faunal studies were accomplished by geochemical analyses of surface sedimen...
