Our knowledge about the glaciation history in the Russian Arctic has to a large extent been based on geomorphological mapping supplemented by studies of short stratigraphical sequences found in exposed sections. Here we present new geochronological data from the Polar Ural Mountains along with a high‐resolution sediment record from Bolshoye Shchuchye, the largest and deepest lake in the mountain range...
The heavy metal cadmium (Cd), an environmentally ubiquitous contaminant, is a potent teratogen in mice. When administered parenterally, it induces an array of malformations that vary in scope and severity with the route, dose, time of administration, and the strain of the animal. When administered intraperitoneally on day 9.0 of gestation, 4 mg/kg cadmium chloride produces forelimb defects (predominantly...
We examined the characteristics of fluorescent powder as dye in bait for the purpose of studying individual foraging areas of the root vole Microtus oeconomus (Pallas, 1776). Colours were visible in the faeces 2-3 h after consumption, and were still evident 36-48 h after the removal of bait. It was possible to distinguish up to four different colours in faeces from one individual if the appropriate...
