Evolution of hosts paying manifold costs of defence.
Hosts are expected to incur several physiological costs in defending against parasites. These include constitutive energetic (or other resource) costs of a defence system, facultative resource costs of deploying defences when parasites strike, and immunopathological costs of collateral damage. Here, we investigate the evolution of host recovery rates, varying the source and magnitude of immune ...
متن کاملPHAS: A Prefix Hijack Alert System
In a BGP prefix hijacking event, a router originates a route to a prefix, but does not provide data delivery to the actual prefix. Prefix hijacking events have been widely reported and are a serious problem in the Internet. This paper presents a new Prefix Hijack Alert System (PHAS). PHAS is a real-time notification system that alerts prefix owners when their BGP origin changes. By providing re...
متن کاملHow viruses hijack the ERAD tuning machinery.
An essential step during the intracellular life cycle of many positive-strand RNA viruses is the rearrangement of host cell membranes to generate membrane-bound replication platforms. For example, Nidovirales and Flaviviridae subvert the membrane of the endoplasmic reticulum (ER) for their replication. However, the absence of conventional ER and secretory pathway markers in virus-induced ER-der...
متن کاملHi-BGP: A Lightweight Hijack-proof Inter-domain Routing Protocol
BGP is the cornerstone of the Internet. However, the implicit trust assumption in BGP’s design destines its inherited vulnerability. Prefix hijacking is one of the large-scale BGPspecific routing anomalies that are able to paralyze the Internet. This calls for a hijack-proof security solution. By putting the protection against prefix hijacking the top priority, we design a lightweight hijack-pr...
متن کاملCollective defence portfolios of ant hosts shift with social parasite pressure.
Host defences become increasingly costly as parasites breach successive lines of defence. Because selection favours hosts that successfully resist parasitism at the lowest possible cost, escalating coevolutionary arms races are likely to drive host defence portfolios towards ever more expensive strategies. We investigated the interplay between host defence portfolios and social parasite pressur...
