Nematodes Associated with Plants from Naturally Acidic Wetlands Soil
Abstract
Four plants, Cyperus ochraceus, Eriocaulon compressum, Lythrum alatum, and Xyris jupicai, growing along the shoreline of an oligotrophic lake in north central Florida were sampled for nematodes. The nematodes recovered were placed in four trophic groups: bacterivores, herbivores, omnivores, and predators. When the nematodes on all plants were considered, 27% were bacterivores, 23% were herbivores, 7% were omnivores, and 43% were predators. Tripyla was the dominant predator and the dominant genus of all nematodes, and Malenchus was the dominant herbivore. Dominance was not clearly pronounced in the other trophic groups. Key words: acidic soil, bacterivore, Cyperus ochraceus, Eriocaulon compressum, herbivore, Lythrum alatum, nematode, oligotrophic lake, omnivore, predator, Xyrisjupicai.Downloads
