摘要: An approach to modelling food web biomass flows among live and dead compartments within species is formulated using metaphysiological principles that characterise population growth in terms of basal metabolism, feeding, senescence exploitation. This leads a unified interactions plants, herbivores, carnivores, scavengers, parasites their resources. Also, dichotomising sessile miners from mobile gatherers resources, with relevance feeding starvation time scales, suggests new classification scheme involving 10 primary categories consumer types. These types, various combinations, rigorously distinguish scavenger parasite, herbivory phytophagy detritivore decomposer. Application the particular consumer-resource demonstrated, culminating construction an anthrax-centred model, parameters applicable Etosha National Park, Namibia, where deaths elephants zebra bacterial pathogen, Bacillus anthracis, provide significant subsidies jackals, vultures other scavengers.
