The Pacific white shrimp (Litopenaeus vannamei), a euryhaline crustacean of significant economic importance, is widely cultivated for its adaptability to diverse salinity levels. Aquaporins (AQPs) are membrane channel proteins that mediate the transport of water and small solutes across biological membranes. Among them, aquaporin 11 (AQP11) is classified as a superaquaporin, and its physiological roles remain unclear. In this...

Niche breadth variation represents a kind of evolutionary trade‐off among traits on resource utility and stress tolerance, which constrains the taxa not to be widely distributed. Regional species pools provide a reservoir of genetic material for organisms with different niche breadths, yet their role in niche breadth variation remains unclear. Here we conducted a large‐scale soil survey across China, including agricultural, fo...
