Volume Method

We conducted an analysis of dabbling duck food habits in the fall of 2002 and 2003 in the Heron Lake system. Gizzard contents of hunter-harvested birds were analyzed using the percent aggregate volume method to determine what food items were consumed and in what quantity. Curltop Ladysthumb (Polygonum lapathifolium) was the food item consumed most often (82.2%) and in the greatest volume (34.2 ml). Sago Pondweed (Stuckenia pectinata) was the only food item of which multiple plant parts were consumed. However, the seeds and tubers only comprised 1.27 and 0.07 of the total aggregate percent.

Abstract The possibility to remove nutrients from two eutrophic fishponds in the Czech Republic through harvesting the dominant submerged species, Ceratophyllum demersum and Stuckenia pectinata, was evaluated. Both plants were sampled in three locations within the fishpond in two-week intervals from late June to late September 2016. In the biomass of both plants nitrogen and phosphorus concentrations were measured and, subsequently, standing stocks of both elements were calculated. The results revealed that the maximum biomass occurred at different times, in June for S. pectinata and in July for C. demersum. The maximum standing stocks were 3.61 and 7.44 g N m−2 and 0.13 and 0.53 g P m−2, respectively.. These values are within the range reported in the literature for the studied species, but they are about one order of magnitude lower when compared to tall emergent species. The total amount of removable nutrients in the monitored fishponds varied between 448 and 842 kg N and between 30.5 and 31.9 kg P.

Phosphorus Partitioning

Abstract Storm water ponds are commonly employed to trap sediments, nutrients and other pollutants in non-point runoff. Aquatic macrophytes are thought to offer enhanced nutrient control via nutrient uptake and other processes. This study sampled and compared the phosphorus contents of water, sediment, and a dominant macrophyte, Stuckenia pectinata (Sago Pond Weed), in a storm water detention pond in the fall of 2013 and 2014. Phosphorus concentrations [ug P (g material)−1] were much higher in macrophyte tissues than in sediment and water, but the areal amounts of phosphorus (mg P m−2) bound in these three forms were ranked differently: sediment>>water>macrophyte, with macrophyte-bound P accounting for only <1–2% of total P in this pond. Macrophyte management may, therefore, have only marginal effectiveness in nutrient control by storm water detention ponds, although macrophytes support a variety of other ecosystem services.

Stuckenia Pectinata

El presente trabajo tuvo como objetivo identificar la composición florística del sistema de drenaje en el Alto Valle de Río Negro y comprender aspectos taxonómicos y biológicos. El listado florístico se obtuvo de 150 censos de vegetación (Braun-Blanquet, 1979) cuyas especies se registraron con valores de cobertura. Las macrófitas acuáticas vasculares se clasificaron según Sculthorpe (1967) y Schmidt-Mumm (1998). Los desagües fueron catalogados en rurales y urbanos según su ubicación y el origen de sus efluentes. Se evaluaron las diferencias florísticas de cada ambiente por medio de la diversidad α -calculada través de la riqueza (S)-, índice de Shannon (H), índice de equidad de Pielou (J), valor de importancia por especie y diversidad β a través del índice de similitud de Sørensen. El catálogo florístico exhibe 45 especies distribuidas en 32 géneros correspondientes a 23 familias, de las cuales las más representativas son Poaceae, Cyperaceae y Typhaceae. Se amplía el área de distribución de ocho especies para la provincia de Río Negro. Predominan las plantas de ciclo perenne, hábito herbáceo, tipo emergente y biotipo helophyta (82%). El mayor valor de importancia en los ambientes urbanos corresponde a Stuckenia pectinata, mientras que en los rurales a Nasturtium officinale y Azolla filiculoides. Esta investigación presenta información de base para estudios posteriores sobre el potencial bioindicador y fitorremediador de las macrófitas acuáticas vasculares del sistema de drenaje.
