Baltimore Ecosystem Study LTER site, station USGS Stream Gage 01589238, Gywnns Falls Tributary, McDonogh, MD, study of total phosphorus in streamwater in units of milligramsPerLiter on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Baltimore Ecosystem Study LTER (BES) contains total phosphorus in streamwater measurements in milligramsPerLiter units and were aggregated to a yearly timescale.

Data from: Environmental DNA detection of rare and invasive fish species in two Great Lakes tributaries
The extraction and characterization of DNA from aquatic environmental samples offers an alternative, non-invasive approach for the detection of rare species. Environmental DNA, coupled with PCR and next-generation sequencing ("metabarcoding"), has proven to be very sensitive for the detection of rare aquatic species. Our study used a custom designed group-specific primer set and next-generation sequencing for the detection of three species at risk; (Eastern Sand Darter, Ammocrypta pellucida; Northern Madtom, Noturus stigmosus; and Silver Shiner, Notropis photogenis), one invasive species (Round Goby, Neogobius melanostomus) and an additional 78 native species from two large Great Lakes tributary rivers in southern Ontario, Canada; the Grand River and the Sydenham River. Out of 82 fish species detected in both rivers using capture-based and eDNA methods, our eDNA method detected 86.2% and 72.0% of the fish species in the Grand River and the Sydenham River, respectively, which included our four target species. Our analyses also identified significant positive and negative species co-occurrence patterns between our target species and other identified species. Our results demonstrate that eDNA metabarcoding that targets the fish community as well as individual species of interest provides a better understanding of factors affecting the target species spatial distribution in an ecosystem than possible with only target species data. Additionally, eDNA is easily implemented as an initial survey tool, or alongside capture-based methods, for improved mapping of species distribution patterns.
Data from: Investigation of nitrogen and phosphorus contents in water in the tributaries of Danjiangkou Reservoir
.As part of the efforts to ensure adequate supply of quality water from Danjiangkou Reservoir to Beijing, surface water were sampled from the tributaries of Danjiangkou Reservoir in normal (May), flood (August) and dry (December) seasons of 2014, and characterized for nitrogen and phosphorus contents as specified in the applicable standards. Test results indicated that 1)the organic pollutions in Sihe and Shendinghe rivers were more serious than those in other tributaries, and the concentrations of nitrogen and phosphorus favoured the growth of most algae; 2) total phosphorus (TP), total nitrogen (TN) and dissolved inorganic nitrogen (DIN) were in the forms of dissolved phosphorus (DTP), dissolved nitrogen (DTN) and nitrate nitrogen (NO3-N) in these seasons, respectively; 3) compared with nitrogen, phosphorus was more likely to block phytoplankton overrunning; 4)TN, TP, permanganate index (CODMn) and other ions were positively correlated. These findings provided an important basis for the effective measures taken later on as appropriate to ensure adequate supply of quality water from Danjiangkou Reservoir to Beijing.

Character evolution has been studied in Mesquite (Maddison and Maddison 2004) using unambiguous optimization: white numbers in black boxes: unique synapomorphies; white numbers in grey boxes: unique autapomorphies or synapomorphies within complex transformations; black numbers in white boxes: convergent autapomorphies. For multistate characters the character state is shown after the hyphen.
