Examples from human and wildlife disease systems are reviewed to illustrate the challenges inherent in understanding the mechanisms and impacts of seasonal environmental drivers, and to highlight general insights that are relevant to other ecological interactions.
Impacts of biodiversity on the emergence and transmission of infectious diseases
Overall, despite many remaining questions, current evidence indicates that preserving intact ecosystems and their endemic biodiversity should generally reduce the prevalence of infectious diseases.
Keeping the herds healthy and alert: implications of predator control for infectious disease
This work develops models for microparasitic and macroparAsitic infection that specify the conditions where predator removal will increase the incidence of parasitic infection, reduce the number of healthy individuals in the prey population and decrease the overall size of the predator population.
The ecology of wildlife diseases
- P. Hudson
- Biology, Geography
The ecology of tick-borne infections in wildlife reservoirs and the role of pathogens in biological conservation are studied.
Prevention of population cycles by parasite removal.
Treatment of the grouse population prevented population crashes, demonstrating that parasites were the cause of the cyclic fluctuations.
Is a healthy ecosystem one that is rich in parasites?
Epidemic Dynamics at the Human-Animal Interface
The use of analytical mathematical tools, particularly modeling, in the development of control policies and research agendas is reviewed and significant gaps are highlighted in analytical efforts during spillover transmission from animals into humans.
Understanding the net effects of pesticides on amphibian trematode infections.
The reduction in exposure to trematodes due to pesticides-induced cercarial mortality was smaller than the pesticide-induced increase in amphibian susceptibility (a trait-mediated effect), suggesting that the net effect of exposure to environmentally realistic levels of pesticides will be to elevate amphibian trematode infections.
Do parasites make prey vulnerable to predation? Red grouse and parasites
The proportion of grouse with high levels of parasite infection increased with the intensity of predator control as measured indirectly through keeper density, and this suggests that predators selectively prey on heavily infected grouse.
Molecular epidemiology of Rabbit haemorrhagic disease virus.
RHDV circulated as an apparently avirulent virus throughout Britain more than 50 years ago and more than 30 years before the disease itself was identified, based on molecular phylogenetic analysis of British and European RHDV sequences.
