... from Imperial College, explains: "This complicated-sounding theory basically says that nutrient availability will only have an impact on the diversity of an organism, if the organism is involved in a ...
... ," the scientists conclude in their paper. "Rather, feeding behavior and fat metabolism are coordinated but independent responses of the nervous system to the perception of nutrient availability."
... in the worms are consistent with the nerve messenger's role as a sensory gauge of nutrient availability, the researchers said. When resources are scarce, worms build up their fat reserves. Thus, the ...

Soils in undisturbed wetlands present harsh conditions, with elevated acidity and low oxygen and nutrient availability in which fewer bacterial groups can survive and grow, they explained. In ...

The research team also found that when a cell is perturbed (when there is a change in the nutrients available or a gene is shut down), the number of biochemical reactions it ...
