Associating with kin selects against disease tolerance

J. C. Walsman, M. Lambe, J. F. Stephenson

The paper models how kin association influences the evolution of resistance and tolerance in hosts, finding that weak kin ties can promote altruistic resistance in infected hosts, reducing disease.

A paradox of parasite resistance: Disease-driven trophic cascades increase the cost of resistance, selecting for lower resistance with parasites than without them

J. C. Walsman, A. T. Strauss, J. Hite, M. S. Shocket, S. R. Hall

The paper shows that parasites can reduce host resistance through resource feedbacks, contradicting the expectation that parasites increase resistance during epidemics.

Social hosts evade predation but have deadlier parasites

J. C. Walsman, M. J. Janecka, D. R. Clark, R. D. Kramp, F. Rovenolt, R. Patrick, R. S. Mohammed, M. Konczal, C. E. Cressler, J. F. Stephenson

The paper shows that predator-induced host social grouping increases parasite transmission, favoring more virulent parasites, and finds that high predation guppy populations have more virulent Gyrodactyus spp. parasites.

Parasite-driven cascades or hydra effects: susceptibility and foraging depression shape parasite-host-resource interactions

J. C. Walsman, A. T. Strauss, S. R. Hall

The paper investigates how parasite-driven mortality and foraging depression influence host density during epidemics, revealing conditions under which trophic cascades or hydra effects occur.

'Resistance is futile': Weaker selection for resistance during larger epidemics further increases prevalence and depresses host density

J. C. Walsman, M. A. Duffy, C. E. Caceres, S. R. Hall

The paper shows that higher epidemic drivers lead to lower host resistance, increasing parasite prevalence and reducing host density through mathematical, experimental, and field analyses.
