Several taper studies have analysed the countries harbouring boreal forests. However, this study presents an initial attempt to develop stem models using fixed- mixed-effects modelling for white Xiaoxing’an Mountains, Ten commonly used were evaluated by 228 dest...

The chemical composition of kelps (e.g. polyphenolics) deters grazing by herbivores, but kelp detritus is potentially a source of nutrition for suspension feeders. The effects of kelp detritus derived from two species [Agarum fimbriatum Harvey and Costaria costata (Turner) Saunders] on feeding of oysters, Crassostrea gigas Thunberg, and mussels, Mytilus trossulus Gould, were examined in feeding...
