Submerged aquatic vegetation, water quality (pH, salinity, and turbidity) and waterfowl abundance data from 1991-2017 in Back Bay, Virginia
<p><span>Back Bay, Virginia, has been documented as an important foraging area for waterfowl since at least the mid-1800s. Expansive submerged plant beds historically supported diverse assemblages of non-breeding waterfowl, however coastal development and other anthropogenic influences have since led to fluctuations in submerged aquatic vegetation (SAV) and an associated decline in waterfowl abundance in the bay. To gain insight into the effects of environmental drivers on waterfowl foraging guilds, our study explores the effects of SAV frequency and water quality on the abundance of dabbling ducks, diving ducks, and swans and geese in Back Bay. We use 8 years of SAV, water quality, and waterfowl monitoring data collected by state and federal agencies to model the effects of salinity, turbidity, pH, and percent frequency of SAV on the relative abundance of waterfowl by foraging guild in Back Bay. The appropriateness of the data and reasonability of the preliminary results were then evaluated through semi-structured interviews with 11 local informants representing state, federal, and non-governmental organizations. Quantitative results indicated that dabbling ducks are affected differently than other guilds by water quality and percent frequency of SAV. Thematic analysis of the interview data revealed a number of potential explanations for the model results, as well as highlighted areas of uncertainty in need of further research. In a test of face validity, participants demonstrated a significant degree of belief in turbidity, salinity, and SAV as drivers of waterfowl abundance, but were not convinced by the potential effects of pH as demonstrated by the model. This mixed methods study provides insights that could potentially influence the management and conservation of non-breeding waterfowl populations by challenging the assumption that particular environmental conditions serve all foraging groups equally.</span></p>
Effect of Water Level and Submergence Time on Leaf Growth, Stoichiometry and Homeostasis of Carex brevicuspis
<p>Water level and submergence time are important factors influencing plant growth and plant C:N:P characteristics in freshwater wetlands. However, the effect of their interaction on plant stoichiometry and homeostasis is far from clear. Here, we performed a controlled experiment using four water levels (0, 10, 20, and 40 cm, relative to the soil surface) and under three submergence times (30, 60, and 90 days) with the aim of investigating the changes in plant growth and stoichiometric characteristics, as well as the strength of N, P, and N:P homeostasis in <em>C. brevicuspis</em> in the Dongting Lake, China. Results showed that biomass, density, height, and total carbon (TC) decreased significantly with increasing water level; however, the latter total nitrogen (TN) and total phosphorus (TP) increased significantly. The highest TN and TP were at 40 cm water level, while the highest C:N, C:P, and N:P ratios were at 0 cm water level. Furthermore, significant stoichiometric homeostasis of <em>C. brevicuspis</em> was found for N (<em>H</em><sub>N</sub>) and P (<em>H</em><sub>P</sub>) except for N:P (<em>H</em><sub>N:P</sub>). <em>H</em><sub>N</sub> and <em>H</em><sub>P </sub>decreased with increasing submergence time, and<em> H</em><sub>N</sub> was consistently greater than <em>H</em><sub>P</sub>, indicating that <em>C. brevicuspis</em> had a weak ability to maintain its internal P balance under long-term submergence. Therefore, the impact of water level and submergence time on plant growth and stoichiometric characteristics in this study, are applicable to the conservation and management of the wetlands dominated with <em>C. brevicuspis</em>.</p>

Data from: Responses of four submerged macrophytes to freshwater snail density (Radix swinhoei) under clear-water conditions: a mesocosm study
<p>Macrophytes play a key role in stabilizing clear-water conditions in shallow freshwater ecosystems. Their populations are maintained by a balance between plant grazing and plant growth. As a freshwater snail commonly found in shallow lakes, <i>Radix swinhoei</i> can affect the growth of submerged macrophytes by removing epiphyton from the surface of aquatic plants and by grazing directly on macrophyte organs. Thus, we conducted a long-term (11-month) experiment to explore the effects of snail density on macrophytes with distinctive structures in an out-door clear-water mesocosm system (with relatively low total nitrogen (TN, 0.66 ± 0.27 mg L<sup>-1</sup>) and total phosphorus (TP, 36 ± 20 μg L<sup>-1</sup>) and a phytoplankton chlorophyll a (Chla) range of 14.8 ± 4.9 μg L<sup>-1</sup>) based on two different snail densities (low and high) and four macrophyte species treatments (<i>Myriophyllum spicatum</i>, <i>Potamogeton wrightii</i>, <i>P. crispus</i>,<i> </i>and <i>P. oxyphyllus</i>). In the high-density treatment, snail biomass and abundance (36.5 ± 16.5 g m<sup>-2</sup> and 169 ± 92 ind m<sup>-2</sup>, respectively) were approximately twice that observed in the low-density treatment, resulting in lower total and aboveground biomass and ramet number in the macrophytes. In addition, plant height and plant volume inhabited (PVI) showed species-specific responses to snail densities, i.e., the height of <i>P. oxyphyllus</i> and PVI of <i>M. spicatum</i> were both higher under low-density treatment. Thus, compared to low-density treatment, the inhibitory effects of long-term high snail density on macrophytes by direct feeding may be greater than the positive effects resulting from epiphyton clearance when under clear-water conditions with low epiphyton biomass. Thus, under clear-water conditions, the growth and community composition of submerged macrophytes could be potentially modified by the manual addition of invertebrates (i.e., snails) to lakes if the inhibitory effects from predatory fish are minor.</p>
