web structure and ecosystem services insights from the Serengeti Biology Diagrams The central organizing theme of this paper is to discuss the dynamics of the Serengeti grassland ecosystem from the perspective of recent developments in food-web theory. The seasonal rainfall patterns that characterize the East African climate create an annually oscillating, large-scale, spatial mo โฆ
We apply this method to a newly compiled plant-mammal food web from the Serengeti ecosystem that includes high taxonomic resolution at the plant level, allowing a simultaneous examination of the signature of both habitat and trophic roles in network structure. Food Chain* Humans Markov Chains Models, Statistical Models, Theoretical The species interactions between herbivores and plants, and carnivores and herbivores, are hierarchically nested in the Serengeti food web, with the largest bodied consumers on each trophic level having the broadest diets that include species from a large variety of different habitats in the ecosystem.

Serengeti food web and food chain by Soma Aref on Prezi Biology Diagrams
The Serengeti food web seemed highly robust to deletion of nodes according to the removal of large to small body-sized nodes, as well as of poor to highly connected nodes, with a slight increase in secondary extinctions as the number of primary species losses progressed . Both yielded R 50 values of 0ยท465 and 0ยท442, respectively. The Serengeti food web. The network is shown organized and colored by group according to the consensus partition method and arranged by trophic level from left (plants) to right (carnivores). The Food Web of the Serengeti. These organisms are generally on the bottom of the food chain. Primary Consumers: A primary consumer is an animal that eats producers - plants. They are also called herbivores, and include animals such as Buffaloes, Gazelles and Zebras.
Groups Identified in the Serengeti Food Web. The groups identified in the Serengeti food web in the consensus partition contain trophically similar species, with all groups restricted to a single trophic level (plants, herbivores, or carnivores). The consensus partition, with 14 groups, is shown in Table 2. The partition includes 2 groups of
