Macroparasite dynamics of migratory host populations.
Spatial variability in host density is a key factor affecting disease dynamics of wildlife, and yet there are few spatially explicit models of host-macroparasite dynamics. This limits our understanding of parasitism in migratory hosts, whose densities change considerably in both space and time. In this paper, we develop a model for host-macroparasite dynamics that considers the directional move...
متن کاملSeasonal forcing in a host-macroparasite system.
Seasonal forcing represents a pervasive source of environmental variability in natural systems. Whilst it is reasonably well understood in interacting populations and host-microparasite systems, it has not been studied in detail for host-macroparasite systems. In this paper we analyse the effect of seasonal forcing in a general host-macroparasite system with explicit inclusion of the parasite l...
متن کاملModels for Host-macroparasite Systems: a Comparison between Spatially Structured and Unstructured Models
We consider classical host-parasite systems consisting of ordinary differential equations for the total numbers of hosts, parasites,and larvae. We also consider a newer, spatially structured model that consists of a partial differential equation for each of those populations. We finally compare the behavior of solutions for the spatially homogeneous model to that of the solutions for the spatia...
متن کاملPatterns of macroparasite aggregation in wildlife host populations.
Frequency distributions from 49 published wildlife host-macroparasite systems were analysed by maximum likelihood for goodness of fit to the negative binomial distribution. In 45 of the 49 (90%) data-sets, the negative binomial distribution provided a statistically satisfactory fit. In the other 4 data-sets the negative binomial distribution still provided a better fit than the Poisson distribu...
متن کاملGenotype-Specific vs. Cross-Reactive Host Immunity against a Macroparasite
Vertebrate hosts often defend themselves against several co-infecting parasite genotypes simultaneously. This has important implications for the ecological dynamics and the evolution of host defence systems and parasite strategies. For example, it can drive the specificity of the adaptive immune system towards high genotype-specificity or cross-reactivity against several parasite genotypes depe...
