Sulfur in lucinid bivalves inhibits intake rates of a molluscivore shorebird ...
A forager?s energy intake rate is usually constrained by a combination of handling time, encounter rate and digestion rate. On top of that, food intake may be constrained when a forager can only process a maximum amount of certain toxic compounds. The latter constraint is well described for herbivor...
