Intraguild predation among snails drives human schistosome amplification despite susceptible host regulation.

Competitors and predators of hosts can alter transmission dynamics within host-parasite systems. Biocontrol aims to harness these effects to mitigate disease, but these attempts may backfire without an understanding of the ecological interactions involved. We investigated how resource competition among snail species affects transmission potential of the human flatworm parasite from its snail intermediate host, .

Parasite transmission in size-structured populations.

Host heterogeneity can affect parasite transmission, but determining underlying traits and incorporating them into transmission models remains challenging. Body size is easily measured and affects numerous ecological interactions, including transmission. In the snail-schistosome system, larger snails have a higher exposure to parasites but lower susceptibility to infection per parasite.

A Baboon Brain Atlas for Magnetic Resonance Imaging and Positron Emission Tomography Image Analysis.

The olive baboon () is phylogenetically proximal to humans. Investigation into the baboon brain has shed light on the function and organization of the human brain, as well as on the mechanistic insights of neurological disorders such as Alzheimer's and Parkinson's. Non-invasive brain imaging, including positron emission tomography (PET) and magnetic resonance imaging (MRI), are the primary outcome measures frequently used in baboon studies.
