query: What is the role of nematomorphs in shaping community ecology?
answer: Nematomorphs, by parasitizing orthopterans, can significantly influence community ecology.  One study showed they make orthopterans 20 times more likely to enter water, impacting the diet of predators like the Kirikuchi char that rely on these insects as a food source.  The absence of nematomorphs can lead to changes in the char's predation patterns and broader ecological effects.
