Causes of Variations in Effectiveness of Bracon cephi (Gahan) (Hymenoptera: Braconidae) as a Parasite of the Wheat Stem Sawfly
TLDR
It appears that moderate to high levels of parasitism required that the crop ripen late in at least one year out of two, whereas a moderately high level occurred even though the weather of the current year was conducive to early ripening, provided that the wheat in the preceding year had ripened late. Expand
The Effect of Temperature on Anopheles Mosquito Population Dynamics and the Potential for Malaria Transmission
TLDR
A temperature-dependent, stage-structured delayed differential equation model is developed to better understand how climate determines risk and reveals that the mosquito population abundance is more sensitive to temperature than previously thought. Expand
Disentangling the interaction among host resources, the immune system and pathogens
TLDR
A series of models are derived to describe the energetic interaction between the immune system and pathogens, from fully independent resources to direct competition for the same resource, and show that increasing within-host resource supply has qualitatively distinct effects under these different scenarios. Expand
Small-amplitude cycles emerge from stage-structured interactions in Daphnia–algal systems
TLDR
It is shown that resource-dependent mortality and a dynamic developmental delay in consumers produces a new type of small-amplitude cycle that coexists with large-amPLitude fluctuations in coupled consumer–resource systems. Expand
CHEMOTHERAPY, WITHIN‐HOST ECOLOGY AND THE FITNESS OF DRUG‐RESISTANT MALARIA PARASITES
TLDR
The hypothesis that the spread of resistance can be slowed by reducing drug treatment and hence restricting competitive release is tested and raises the question whether the aggressive treatment regimens aimed at complete parasite clearance are the best resistance‐management strategies for humans. Expand
The fitness of drug‐resistant malaria parasites in a rodent model: multiplicity of infection
TLDR
Strong competitive suppression of resistant parasites in untreated infections and marked competitive release following treatment are found and the magnitude of competitive suppression depended on competitor identity. Expand
Enhanced Transmission of Drug-Resistant Parasites to Mosquitoes following Drug Treatment in Rodent Malaria
TLDR
It is reported that for the murine model Plasmodium chabaudi, co-infection with drug-sensitive parasites can prevent the transmission of initially rare resistant parasites to mosquitoes, and the genetic composition of gametocyte populations in host venous blood accurately reflects the Genetic composition ofgametocytes taken up by mosquitoes. Expand
Starvation reveals the cause of infection-induced castration and gigantism
TLDR
The results show that starvation primarily affects investment in reproduction, and increasing starvation stress reduces gigantism and parasite fitness without affecting castration, consistent with an energetic structure where the parasite uses growth energy as a resource. Expand
