Winter biomass and nutrient values of three seagrass species as potential foods for redheads (Aythya americana eyton) in Chandeleur Sound, Louisiana
We studied biomass and macronutrient content of Halodule wrightii (shoalgrass) throughout the winter and of Thalassia testudinum (turtlegrass) and Syringodium filiforme (manateegrass) in January in Chandeleur Sound, Louisiana Halodule , the primary fcod of wintering redheads, had the lowest biomass of the three species on the study area in mid-winter. Macronutrient content of Halodule did not change during the winter, but aboveground and belowground biomass showed a 90 and 49% ( P <0.0001) decrease from October to March. Macronutrient content seems not to be the basis for selection by redheads of Halodule over the other two seagrass species or of selection of belowground over aboveground parts.
