Post-2000 efforts to protect China’s grassland areas are distinct from earlier efforts in that funding for the most recent round of policies and programs is commensurate with the task. Among the most controversial of the current policies is the provision of an annual subsidy ranging from 2 yuan to 20 yuan/mu (1/15 hectare) to herders to not graze livestock contracted by their families for periods from 3-10 years. Many other recent policies, such as fencing programs and hunting and burning bans to protect keystone species are also controversial. Ideally, the policies are intended to protect grassland ecological systems while assuring …

In most host-pathogen systems, the key feature of transmission dynamics and rate of spread of a parasite or disease is the variation among hosts in the numbers of parasites they harbor and the factors controlling infection. Pathogens are typically aggregated across their host populations: relatively few individuals are heavily infected, while most potential hosts suffer light infections or remain uninfected. Aggregation among hosts may be generated by variation among individuals in their exposure to parasite infective stages and by variation in susceptibility once an infectious agent has been encountered. Host heterogeneity in parasite burden has a strong influence on the …
