CSR theory2), these drivers are often confounded in real ecosystems. Agricultural systems in particular, tend to be found on a continuum between low intensity (low disturbance, no nutrient input) and high intensity (high disturbance, such as mowing, and high nutrient input). We ...
A total of 85 biochemical compounds satisfactorily retained and baseline separated were tentatively identified from the different seaweed extracts analyzed, which could be broadly categorized into diverse phytochemical classes including fatty acids and their derivatives, flavonoids, phenolic acid, phlorotannins...

We investigated this effect of breast milk by comparing the suscep- tibility to infection assessed in terms of adherent bacterial colo- nization of the intestinal tissue (AdC) and bacterial translocation (BT) between breast-fed and formula-fed newborn rats. Three- day-old rat pups were ...
Notwithstanding differences between the yeasts, arabinitol, glycerol, succinic acid and ethyl acetate were produced from 8 sugars but not from lactose. Although the yield of lactic acid was generally low; it was still produced from all sugars. Citric acid was produced widely but negligibly from...
