On spatiotemporal patchiness and the coexistence of five species of Chronogaster (Nematoda: Chronogasteridae) in a riparian wetland.

abstract：:Understanding the differences in fine-root traits among different species is essential to gain a detailed understanding of resource conservation and acquisition strategies of plants. We aimed to explore whether certain root traits are consistent among subsets of species and characterize species together into meaningfu...
