Fatty acid signatures (FAS) are currently used in food web studies to provide insights into long term feeding habits of predators based on the degree of similarity between their FAS and that of their prey. To date, FAS data of fish from Lake Ontario are limited and are required to better understand how FAS variation in prey fish affects top predators. In this study, three major prey fish (alewife - Alosa pseudoharengus, rainbow smelt - Osmerus mordax, and round goby - Neogobius melanostomus) were collected at three sites along the south shore of Lake Ontario (Olcott, Rochester, and Oswego) during the spring and fall of 2013. Using multivariate statistics, we will compare FAS among species as well as their spatiotemporal variation. These data will further our understanding of predator-prey interactions in Lake Ontario’s food web.

EFFECT OF SAMPLING TIME ON CAMERA TRAP RESULTS

Joseph M. Beck, John VanNiel
Department of Environmental Conservation and Horticulture, Finger Lakes Community College, 3325 Marvin Sands Drive, Canandaigua, New York 14424.

Ten weeks of camera trap data from a single location was analyzed for mammal species richness, latency to detection and capture frequency for each species. The camera trap was placed in a wetland area at the FLCC Muller Field Station. Analyses were completed for the entire ten week period as well as sub-sampling for two- and one-week periods in order to compare results and recommend duration of placement for future studies. A total of ten species were captured with raccoon (Procyon lotor), Eastern chipmunk (Tamias striatus), and North American river otter (Lontra canadensis) being observed most frequently, in that order. The species with the shortest latency to detection was the deer mouse (Peromyscus sp.) which was viewed on the first day. The species with the longest latency to detection was American black bear (Ursus americanus), having been first viewed on the last day of the study.

BIOLOGICAL SURVEY FOR INVASIVE SPECIES IN LOON LAKE AND THE SURROUNDING WATERSHED, STEUBEN COUNTY, NEW YORK

Managing invasive species first requires knowledge of their local presence, frequency of occurrence and population abundance.  With limited existing information available for Loon Lake and its watershed, this project was undertaken to fill gaps in knowledge by surveying the fish and littoral communities in the lake, and terrestrial plants in the surrounding upland landscape.  Fieldwork was conducted during fall 2014 and invasive species with an earlier phenology may not have been detected, so these survey results should be considered a working inventory.

Lake fisheries were assessed through afternoon and evening electro-shocking and detected 13 species with yellow perch (Perca flavescens) being most common.  A regionally uncommon species, the creek chubsucker (Erimyzon oblongus) was present.  The only invasive fish species was the common or European carp (Cyprinus carpio).

Lake macrophytes and other littoral organisms were documented by raking in deeper waters and wading in shallower areas.  Twenty seven macrophytes were present, including submerged (n=13), floating leaved (n=9) and emergent (n=5) species. Invasive macrophytes included Eurasian water milfoil (Myriophyllum spicatum), curly leaf pondweed (Potamogeton crispus) and yellow iris (Iris pseudoacorus).  Invasive dreissenid mussels, including regionally abundant zebra mussels (Dreissena polymorpha), were not detected in Loon Lake but the introduced banded mystery snail (Viviparous georgianus) was common.

Visual survey of the watershed from municipal roads, farm lanes and otherwise accessible areas helped determine the extent of terrestrial invasive plants.  Notable invasive species observed included Norway maple (Acer platanoides), goutweed (Aegopodium podagraria), garlic mustard (Alliaria petiolata), common mugwort (Artemisia vulgaris), Japanese barberry (Berberis thunbergii), spotted knapweed (Centaurea maculosa), Canada thistle (Cirsium arvense), crown vetch (Coronilla varia), autumn olive (Elaeagnus umbellata), Japanese knotweed (Fallopia japonica), dame’s rocket (Hesperis matronalis), everlasting pea (Lathyrus latifolius), Tartarian honeysuckle (Lonicera tatarica), moneywort (Lysimachia nummularia), wild parsnip (Pastinaca sativa), reed canary grass (Phalaris arundinacea), European buckthorn (Rhamnus cathartica), black locust (Robinia pseudoacacia), sweetbrier rose (Rosa eglanteria), multiflora rose (Rosa multiflora), and garden valerian (Valeriana officinalis).

This research study was supported by the Finger Lakes Partnership for Regional Invasive Species Management (FL-PRISM).

WHAT’S HAPPENING TO ZEBRA MUSSELS (Dreissena polymorpha) IN HONEOYE LAKE? 

Bruce Gilman, Jason Hanselman and Nadia Harvieux
Department of Environmental Conservation and Horticulture, Finger Lakes Community College, 3325 Marvin Sands Drive, Canandaigua, New York 14424.

In 2001, unusually large foam streaks appeared on the surface of Canandaigua Lake while at the same time zebra mussel (Dreissena polymorpha) shells were washing up in great numbers along the shoreline.  It was hypothesized that a mussel die-off had occurred and that their dead remains were contributing to the foam.  The following year, a PONAR dredge was used to sample the lake bottom at several locations.  Using shell length as a proxy for mussel age, dredge data indicated that nearly all of the living mussels were less than a year old, verifying that a die-off had indeed taken place the prior year.  To compare the Canandaigua Lake “recolonizing” population age-class structure to a normal one composed of multiple year cohorts, the Honeoye Lake zebra mussel population was also sampled in the summer of 2002.

During fall 2013, Honeoye Lake residents reported that they were finding very few zebra mussels on their docks when they were removed in preparation for the winter.  Had a die-off of mussels also occurred in Honeoye Lake?  There were no tell-tale foam streaks or large wrack lines of empty shells, but perhaps those conditions should not have been expected.  With most of the Honeoye lake bottom composed of soft substrates, the zebra mussel populations were never as large as in neighboring Canandaigua Lake.  Perhaps they had declined due to lack of palatable algae brought on by their own selective filter feeding on the phytoplankton community.  The best way to verify a zebra mussel population decline would be to resample the same locations studied in 2002, and compare results.  This would also provide an opportunity to discover if other benthic invasive species had entered the lake, especially Asian clams (Corbicula fluminea) and quagga mussels (Dreissena rostriformis bugensis).

In summer 2014, the zebra mussel population in Honeoye Lake was again sampled at the same locations.  Samples were processed by tallying and weighing the mussels.  Overall, the zebra mussel density declined by about 30% (from 1647/m2 in 2002 to 1199/m2 in 2014).  Total mussel biomass declined by about 35% (from 292 g/m2 in 2002 to 188 g/m2 in 2014).  Indeed the perception of the public was correct.  And about the other benthic invasive species, both good news and bad news – no quagga mussels or Asian clams were found in the dredge samples but four European fingernail clams (Sphaerium corneum) were collected on gravelly substrates along the northeastern shore of the Honeoye Lake.

EIGHTEEN YEAR TREND IN SUMMER SURFACE WATER TEMPERATURES (C°) OF CANANDAIGUA LAKE, NEW YORK. 

Bruce Gilman1 and Kevin Olvany2
1Muller Field Station, Department of Environmental Conservation and Horticulture, Finger Lakes Community College, 3325 Marvin Sands Drive, Canandaigua, New York 14424, and 2Canandaigua Lake Watershed Council, 205 Saltonstall Street, Canandaigua, New York 14424.

Perhaps no other factor has as strong an influence on the limnology of Canandaigua Lake as water temperature. Nutrient solubility, water density, water circulation patterns, photosynthesis and biological respiration are all directly regulated by water temperature regime. Monthly temperature profiles through the water column have been collected April to November at two mid-lake monitoring stations since 1996.  These depth profiles track the change from nearly isothermal conditions in late April, to periods of strong stratification in summer, then finally a return to nearly isothermal conditions in late November that drive the fall turnover typical of this warm, monomictic lake.

Summer surface water temperatures from the top of these depth profiles may be a good indicator of long-term atmospheric temperature tendencies due to the high specific heat of water.  Simply put, lakes are less susceptible to the daily fluctuations reported from terrestrial weather monitoring stations because they buffer atmospheric temperature extremes.  Average summer surface water temperatures, calculated as the mean of surface water temperatures during the end of June, July and August at the Deep Run and Seneca Point mid-lake stations, document a variable but gradual increase over the 18 years of record.  A trend line fit to the mean temperature data indicates a 2.2°C increase since 1996 thus providing information on the extent of recent climate change in western New York.  Warmer summer surface water likely alters biological relationships among lake organisms and may, in part, contribute to the recent dominance of blue-green algae within the phytoplankton community.

Creating an ArcGIS Mapbook for Aquatic Invasive Species in NY Lakes

Brandon Kenny and Eric Scaraglino
Rochester Institute of Technology, One Lomb Memorial Drive, Rochester, NY 14623-5603

This capstone project is developing an ArcGIS Mapbook showing invasive aquatic vegetation in NY lakes monitored by the NY iMap Invasives Program, in partnership with the NY State Federation of Lake Associations (NYSFOLA).  The project goal is to provide an easy to use tool to help the lake associations monitor the spread of aquatic invasive species.  The Mapbook displays each lake separately, using ArcGIS’s Data Driven Page (DDP) tool to automate the layouts within a map book. Linked to the map pages are data pages containing information about the lake properties and the invasive species found within the lakes.  Data pages provide a description and photo of the species, steps on how to identify the species, how to report findings to iMapInvasive, and when possible, treatments recommended for eradication or control.  By providing a less technical digital tool for mapping lake information, the mapbook is geared to promote public outreach and help lake association members become more involved in maintaining the health of their lake’s ecosystem.  This project will be formally presented at the NYSFOLA Annual Conference in May, 2015.

THIRTY YEARS OF CHANGE IN THE FALL STANDING CROP BIOMASS OF MACROPHYTE COMMUNITIES IN HONEOYE LAKE. 

Bruce Gilman, John Foust, and Jason Hanselman,
Department of Environmental Conservation and Horticulture, Finger Lakes Community College, 3325 Marvin Sands Drive, Canandaigua, New York 14424-8395.

Aquatic macrophyte communities were sampled along 20 transects through use of SCUBA.  Each transect began at the shoreline and extended perpendicularly towards the lake center.  Plants were hand harvested within submerged quadrat frames from 5 sites of varying water depths along each transect, then sorted by species and air-dried in the college greenhouse.  Individual sites were summarized by species composition, sample richness, overall diversity and standing crop biomass.  Among the vegetated samples, richness ranged from 1 to 13 species while dry weight biomass ranged from 0.06 g/m2 to 516.56 g/m2.

Similar investigations in 1984, 1994 and 2004 allowed for long-term trend analyses in macrophyte community structure and function.  Trends are hypothesized to result, in part, from changes in water quality following the installation of a perimeter sewer system in 1980, the introduction and establishment of an invasive zebra mussel (Dreissena polymorpha) population, resource competition between the macrophyte and phytoplankton communities, and changes in external nutrient loading associated with an increase in extreme storm events.  Macrophyte community response to changes in water clarity (Zsd) has altered the maximum depth of the littoral zone during the thirty years of record but the optimal depth range of individual species has remained fairly constant.  In 2014, macrophyte community composition was dominated by native species including eelgrass (Vallisneria americana), coontail (Ceratophyllum demersum), flat-stem pondweed (Potamogeton zosteriformis), water stargrass (Heteranthera dubia), small pondweed (Potamogeton pusillus), elodea (Elodea canadensis), star-leaved duckweed (Lemna trisulca), large-leaf pondweed (Potamogeton amplifolius) and Richardson’ pondweed (Potamogeton richardsonii).  Invasive species included Eurasian water milfoil (Myriophyllum spicatum) and curly-leaf pondweed (Potamogeton crispus).

Engineered nanomaterials are increasingly adopted in renewable energy systems, as in the case of nano-iron phosphate used to enhance performance of lithium-ion batteries. However, the potential ecosystem-level impacts of nanomaterial release to the environment when these batteries are disposed or recycled is poorly understood. To address this knowledge gap, this study has developed a microcosm-based approach to analyze the effect of nano-iron phosphate on the biogeochemistry and ecosystem health on a freshwater ecosystem. These impacts were assessed by measuring sediment-water column fluxes of oxygen, nitrogen and phosphorus, microalgal photosynthesis and benthic ecosystem metabolism. No acute (48-hour) or chronic (30 days) impacts were observed, at both environmentally relevant concentrations or extreme concentrations. This is likely due to poor solubility of nano-iron phosphate in water. Long-term dissociation in anoxic sediments did not appear to have an impact on the benthic communities. This poster will report the development of the novel microcosm approach, the variable aqueous solubility resulting from two material preparation methods, and the acute and chronic impacts to ecosystem health. These experiments will elucidate the environmental implications of nanomaterial production and use, and contribute to a greater understanding of their fate and impact on the natural environment.

Like many watersheds, the headwaters of Castle Creek (Geneva, NY) are surrounded by a mixture of agricultural and forested land, flowing through suburbia and then intense urbanization.  As indicators of water quality, benthic macroinvertebrate (BMI) communities also vary depending on available habitat and season. This long-term study examines both spatial and temporal changes in BMI across rural-urban sites over two years. BMI were sampled in riffles (5m diagonal) using a D-net, then subsampled and identified in the lab. Water quality (dissolved oxygen, temperature, pH, conductivity and chloride) was also measured at each site.  A Percent Model Affinity (PMA) score was calculated for each site and date.  Preliminary data indicate that suburban sites generally have the highest PMA scores. Temporal variability occurs within each site, most likely due to changes in habitat and life history stages of benthos.  However, there was a decreasing trend in channel stability and percent predator metrics along the rural-urban gradient. Chloride and conductivity were significantly higher in suburban and urban sites than in rural sites. It was determined that urbanization impacts on Castle Creek are severe throughout the year, and restoration of downstream reaches would promote better stream health.

Century- and Decade-Scale Fluctuations in Seneca Lake Major Ion and Water Clarity

Seneca Lake has elevated chloride and sodium ion concentrations compared to the smaller Finger Lakes in central New York.  Previous research hypothesized that the deep lake bottom intersects Silurian halite (NaCl) deposits, which facilitated a groundwater connection and a constant flux of saline groundwater over time to the lake.  Municipal water supply data from the past century and our monitoring efforts reveal that Seneca Lake chloride concentrations increased from 50 to over 200 ppm from 1900 to 1970 and decreased since then to 120 ppm in 2014.  The change does not mimic century-scale changes from increased road salt applications observed in Skaneateles, Hemlock and Canadice Lakes but instead parallels local salt mining activities, which may have caused a fluctuation in the saline groundwater flux. 

Weekly Secchi disk depth and chlorophyll-a concentration data over the past two decades reveal a rapid increase in water clarity after the invasion of Dreissena species in 1992 (zebra then quagga a decade later) and a subsequent decrease in water clarity since 1998 due to nutrient loading and declining Dreissena populations.  Increased water clarity during the early spring since 2007 and from shallow (25 m) to deep (100 m) water sites suggests continued seasonal and spatial influence by mussel filtration.

Early Detection of Invasive Species Trhough Assessment of the Aquatic Plant Community in Northern Seneca and Cayuga Lakes, New York.

Samuel Burrell, Lisa Cleckner, and Hilary R. Mosher
Hobart and William Smith Colleges, Geneva, NY
Twenty sampling points randomly placed within each of the northern ends of Seneca and Cayuga Lakes were surveyed using a rake-toss method in order to obtain plant species distributions. In an effort to monitor for harmful invasive species such as Hydrilla verticillata, careful analysis of plant genus and species were recorded for each rake-toss. A total of twelve species of aquatic plants and algae were found at the Cayuga and Seneca Lakes sampling sites, with invasive Eurasian watermilfoil (Myriophyllum spicatum) and curly-leaf pondweed (Potamogeton crispus) proving more dominant in Seneca Lake despite a larger total plant density in Cayuga Lake. Overall, native plants still collectively dominated invasive plants, making up over half the total plant frequency on both lakes. The absence of Hydrilla was reassuring, and these results provide a good basis for an otherwise lacking amount of information about macrophyte population composition and density.

Zurich Bog is a National Natural Historic Landmark in Arcadia, New York owned by the Bergen Swamp Preservation Society.  This 650 acres site includes various types of wetland communities that are relatively rare in this region.  Students in Finger Lakes Community College’s Spring 2014 Wetland Science and Practice class completed a GIS-based ecological community map of Zurich Bog using the Draft Ecological Communities of New York State classification scheme by the New York State Department of Environmental Conservation (DEC). Existing geospatial data layers were used to identify likely changes in ecological communities and qualitative vegetation sampling was conducted to classify and delineate community boundaries.  In addition, the students completed a preliminary hydrologic monitoring study comparing differences in water level fluctuations in two of the mapped ecological communities, an area dominated by Sphagnum spp. and ericaceous shrubs as well as an area with a greater presence of sedges and grasses.  Continuous water level measurements were recorded for a week-long period in early April using Hobo water level loggers.
