Particularly, the extinction of a host species can\u00a0result in the co-extinction of the parasites that infect that host and may also influence the overall network of host-parasite interactions. This idea was the premise of a recent article by Tad Dallas and Emily Cornelius in <em>Nature Scientific Reports<\/em>. The specific goals were\u00a0to determine the degree to which each host contributed to the structure of the host-parasite network, to determine if that contribution was predictable based on host traits, and then to examine what would happen to the network if these hosts were sequentially removed. To address this, they studied a data set on\u00a0fish parasites in the Paran\u00e1 River Floodplain that had been collected as part of a long term research effort. What they found was that hosts contributed differentially to network structure, implying that\u00a0certain hosts function as\u00a0keystone species whose loss would cause a disproportionately large reduction in parasite diversity and aspects of network structure previously related to network stability.
