a requirement of the hypothesis that PT started in Neoproterozoic time is that the immediately preceding epoch – the Mesoproterozoic – was a SL episode. Stern10identified three SL indicators: (1) elevated thermal regime; (2) abundance of unusual dry magmas such as A-type granites and anorthosi...
Mesopelagic prey have a more restricted vertical migration and higher relative abundance closer to the surface where Circumpolar Deep Water rises to shallower depths. Combining these observations with a future projection of Southern Ocean conditions we show that changes in the coupling of surface and ...
Natural abundance of 15N and 13C in fish tissues and the use of stable isotopes as dietary protein tracers in rainbow trout and gilthead sea bream For developing efficient diets, two sets of experiments examined whether the use and allocation of dietary protein can be traced by labelling with ...
