Pond ecosystems can have substantial impacts on water quality, support diverse flora and fauna, and provide essential resources for human consumption. However, their small size makes them vulnerable to biological invasions. Floating primrose-willow (Ludwigia peploides [(Kunth) P.H. Raven]; hereafter FPW) is an aquatic plant known to in the littoral areas of pond systems and grows in dense mats horizontally and vertically similarly to the aquatic plant common water hyacinth (Eichhornia crassipes [Emmerik]). To understand how FPW influences pond environmental conditions and aquatic macroinvertebrate communities, we compared littoral habitats dominated by FPW to adjacent non-vegetated habitats within an invaded pond at the Kern Water Bank, CA. We predicted that nutrient concentrations would be greater and light availability and water clarity will be reduced in habitats with FPW compared to habitats without aquatic vegetation due to the dense vegetation mats that limit sunlight reaching the water column. We also predicted that macroinvertebrate density and diversity would be highest in FPW habitats and that macroinvertebrate communities would differ taxonomically and functionally, with collector-gatherers, detritivores, and predators dominating areas beneath FPW mats, and grazers and predators dominating non-vegetated habitats. Colorimetric methods were used to determine nutrient concentrations, background environmental data were measured across habitat types, and macroinvertebrates were collected using D-frame net sweeps within 1.0 m² plots (n = 10). Organisms were identified to family level and assigned to functional feeding groups to evaluate taxonomic and functional differences between habitats. Preliminary results suggest that FPW presence produces measurable differences in environmental conditions and macroinvertebrate communities. Littoral areas with FPW supported greater macroinvertebrate abundance and higher diversity compared to non-vegetated habitats. Macroinvertebrate communities beneath FPW mats were dominated by Chironomidae and copepods, whereas Daphnia spp. dominated non-vegetated zones. Understanding how invasive aquatic plants reshape pond habitats will aid in effective management and restoration efforts in freshwater systems.
