• Sommario/riassunto: Food chains are representations of the predator-prey relationships ; between species within an ecosystem or habitat. This title presents research across a spectrum in the study of food chains, including ciguatera shellfish poisoning; survival domain of the top-predator in lattice ecosystems; and, the Azorean cheesemaking food chain.
