Impacts of Minnow Species Composition on Marsh Feeding Ecology: A Look at Minnow Composition in Heron Marsh

Mon, 11/30/2020 - 16:07
Abstract: Minnows play an important role in marsh ecosystems as both predator and prey. The abundance of minnows in water systems makes them important tools for studying the feeding ecology of small prey fish. Minnow traps were set within specific regions and plots located in the Heron Marsh in the Adirondack Park, New York. These traps were baited and checked the next day, and minnows were identified by species then released. Trophic guilds were assigned to each minnow species based on literature and feeding habits. ANOVA tests were conducted to compare minnow species composition from the fall of 2020 in all regions of the marsh. Histograms were used to compare length-frequency over time and sites where minnows frequent. The composition of trophic guilds showed that carnivores were scarce, as creek chub only over 100mm were considered predatory, and they were not as frequent as smaller creek chub. Omnivorous generalist feeders were common but no specific site in the marsh had more omnivorous feeders than other sites. Finally, the abundance of insectivores was high in most sites, and highest in the forest ecology trail site. Length frequency of the two most caught fish, creek chub and finescale dace, were represented with histograms. Creek chub under 100mm were more abundant in every site than individuals larger than 100mm. Similarly, finescale dace 70mm and smaller were more common in every site.

An Ecological History of the Albany Pine Bush, Albany NY

Mon, 11/30/2020 - 15:45
Abstract: Paleoecology allows us to look backward in time thousands of years to see the long-term ecological history of an area. The main focus was to conduct the first exploratory investigations of the wetland located in the Albany Pine Bush Preserve (APBP) and Stump Pond deposits and the first directly dated ecological history of the pine bush. Irregular fire regimes and land development have caused a massive loss to the pine bush. Between 1940 and 1990 the pine bush has experienced an 81% change in land cover. Despite this, the APBP is home to many rare and endangered species in need of habitat restoration. Three samples (APB1-A, APB1-C, & APB2) were collected from a wetland within the boundaries of the APBP and one sample (Stump-1) was collected from a nearby pond. Cores were analyzed for pollen assemblages to reconstruct the tree community. APB cores revealed that Pinus and Quercus pollen grains made up the majority of all pollen found from Present – 6600 years ago Stump-1 pollen assemblages were dominated by Pinus and Picea indicating that between 6600 and 10,600 years ago the ecosystem transformed into the pitch pine- scrub oak ecosystem we see today. This information can help the APBP justify future preservation and restoration work.

Small Mammal Presence and Predation of Boreal Bird Nests in Forested vs. Open Peatlands in the Northern Adirondack Park, NY

Mon, 11/30/2020 - 16:07
Abstract: Recent declines of many boreal birds have been documented in the last decade and area attributed to changing climate and human development. One factor that has not been studied in the critical boreal peatland habitats in the Adirondack Park is the occurrence and influence of small mammals preying on passerine boreal bird nests. The hypotheses tested were (1) small mammals occupy forested peatlands in a higher abundance than open peatlands at the study sites and (2) boreal bird nests in forested peatlands are more likely to be preyed on by small mammals than nests in open peatlands. Baited track tubes were placed on transects within open and forested peatlands and activity was estimated from prints left on contact paper, and artificial nests and eggs were used to compare the difference in nest predation between open and forested peatlands. There was a difference in small mammal activity between forested and open bog at the Paul Smith’s VIC study area, but results were not significant at Shingle Shanty medium bog. 67% of artificial nests in the forested bog at the VIC were destroyed, and only 14% were destroyed in the open bog. At Shingle Shanty, 83% of the nests were destroyed in the forested bog and 0% of artificial nests were damaged in the open bog.

Distribution and Abundance of Larval Yellow Perch (Perca flavescens) in Lake St. Clair and the Lower St. Clair River, 2018

Mon, 12/02/2019 - 21:23
Abstract: Spatial and temporal dynamics of fish larvae play an important role in determining year-class strength due to variation in habitat quality and food resources that influence larval growth, development, and survival rates. Surveys conducted during the past decade in the St. Clair-Detroit River System have revealed a decline of yellow perch. Genetic and microchemistry analyses showed that these fish make a substantial contribution to the yellow perch stock in western Lake Erie. Our study examines the spatial and temporal distributions of larval yellow perch in Lake St. Clair and the lower St. Clair River to identify important spawning and nursery areas and other ecological factors influencing their early life history. We employed a lake-wide daytime sampling program in 2018 using paired bongo nets to sample pelagic larvae throughout 33 sample locations beginning in mid-March before yellow perch had hatched and continued through mid-July when larvae were absent from samples. Based on our spatial analysis results, Mitchell Bay and Anchor Bay appear as the primary regions for yellow perch spawning habitat and/or nursery grounds for larvae. It is difficult to conclude which factors are influencing the distribution of yellow perch the greatest, but submerged aquatic vegetation, water temperature and clarity likely influence yellow perch vital rates, based on our study. The results from this study give us a growing understanding of the ecological interactions underlying larval yellow perch and their habitat usage during their early life history.

Lower St. Regis Lake Survey: A Comparative Study of Fish Population Structure and Function over Time

Thu, 12/13/2018 - 14:24
Abstract: Lake surveys are performed on bodies of water to provide a health analysis of fish populations over time. Lake surveys can be conducted in a variety of ways to attain specific data. Lower St. Regis Lake was surveyed to determine the fish community composition and to understand fish population traits. Using fyke nets placed at six predetermined locations for 24 hours, as well as fishing, we collected data for age, length (mm), weight (g), and parasites present. Data was analyzed in the lab using Excel to form graphs and tables to demonstrate our findings. Catch rates were lower compared to years before and comparing our data to New York State Department of Conservation data found that our length-at-age data was lower for the six-species sampled. Pumpkinseed and yellow perch were the only two species to have over twenty fish sampled. Decreased air temperatures brought in by a cold front during the week of our sampling may have been a reason for our lower number of fish caught. Mesh size is also a bias while using these nets as smaller fish can escape, and predatory fish can prey on smaller fish while in the net. Some species of fish such as black crappie may be more susceptible to capture due to its habit of associating with structure.

Assessing the Use of Backpack Electrofishing to Index Age-0 Fish Abundance in Woody Structure Adjacent to the Lakeshore

Fri, 12/14/2018 - 10:50
Abstract: The preservation and monitoring of age-0 fishes and their habitat is imperative to the overall health of a lake and its fishery. The effectiveness of backpack electrofishing at capturing age-0 fishes along shorelines with coarse woody structure was assessed by attempting to correlate electrofishing catch rates with known population sizes. A 60x2m controlled study area along the shoreline of Lower St. Regis lake was selected and blocked off through use of a net encompassing the perimeter. Known population sizes were stocked into the net and a three-pass electrofishing depletion was conducted within the study area. Results indicated that there was no significant correlation between the known population size and the population estimate generated through electrofishing (p = 0.172). The lack of correlation may have been due to failure of the block net encompassing the study area.

Minnow Abundance in Heron Marsh: Spatial Variation, the Status of the Non-Native Fathead Minnow, and Hybridized Redbelly and Finescale Dace

Fri, 12/14/2018 - 09:27
Abstract: Due to their distinct influence on surrounding ecosystems and food web dynamics, minnow populations have been monitored in Heron Marsh, in the northern Adirondacks in New York, since fall of 2012. This study documented the presence of species known to predate on minnows, the hybridization between redbelly dace (Chrosomus eos) and finescale dace (Phoxinus neogaeus), and the presence of the recently documented fathead minnow (Pimephales prometas). To survey piscivores, two fyke nets were set around the marsh for one trap night. The fishes were then identified and measured. The collection of predators is part of a preliminary study to document the presence of predator fish species within Heron Marsh. Minnow data was collected via minnow traps set at long term study sites and one new site. The traps were set over night and collected the following day. The minnows were identified and measured to the nearest mm. When analyzing the data collected in the field, the data from previous years was compared to this years data. The findings indicate that hybrids of redbelly and finescale dace can be observed only at sites where both parent species exist. This 2018 study was the first one to document hybrid species though they have been observed in past years. The status of the fathead minnow is not significantly different from findings from 2017 however, their populations are noticeably smaller than previous years. Predator composition was primarily brown bullhead (Ameiurus nebulosus) and creek chub (Semtilus atromaculatus).

A USE VERSUS AVAILABILITY DIET STUDY OF AGE-0 FISHES IN NEAR SHORE WOODY STRUCTURE

Thu, 12/13/2018 - 14:09
Abstract: In 2014, the need for an ecological restoration program began at Paul Smiths College in attempt to restore or improve the shoreline along Lower St. Regis Lake. When restoring a shoreline, one must look at what organisms are using the area and how they are doing it. Invertebrates and fishes play a large role in distinguishing problems or changes in an environment, so we sampled both to add useful knowledge to the restoration program. Specifically, we looked to see if fishes were selecting for specific invertebrates (food), or if they did not have a preference. We used a backpack electrofishing unit to sample young of the year fishes near shore along three 60-meter segments, and a 100-foot bag seine to collect fishes offshore along the same segments. Invertebrates were sampled along the same segments and was done so by picking up all coarse woody debris and brushing the pieces off with our hands into a sieve bucket. Woody debris too large to pick up were scraped underwater using a standard kick net. Invertebrates were identified to order level, and fish stomach contents were also identified to the order so that we could conduct a comparison. After using a Chi Square test, we found that according to our p-value (0.2796) fishes were not selecting against any individual taxonomic group. Smallmouth bass were also the dominant present species along nearshore woody debris which could either suggest a higher recruitment than other species, a preference of use by the smallmouth bass, or human introduced capturing bias. Although we can’t indefinitely say fishes were selecting for Dipterans, data shows that dipterans made up just 4.5% of the total invertebrate composition on CWD but made up 9% of the fishes’ stomach contents suggesting fishes may be selecting for them.

Feasibility Study of an Outdoor Classroom Area in Glenview Preserve

Fri, 12/14/2018 - 21:36
Abstract: The Glenview Property is 238 acres with a lot of potential. One of those potentials could be to create a sustainable education area for the public. The Glenview Preserve is known for its scenic view of the mountains, its lowland boreal forest, and its productive farmland. The Adirondacks are known for its forestry, agriculture, and open space recreation. The Adirondack Land Trust owns and manages this area. The ideal main uses of this property are agricultural, educational, sustainable outreach programs, and a balance between natural and artificial scenery (Adirondack Land Trust, 2017). Within the Adirondacks, where the beauty is breathtaking, recreation is at world-class level, and the land is environmentally protected, experiences are held in order to promote environmental awareness. With local resources and the natural growing land space, a sustainable education area can be built. Additional projects within the area includes an amphitheater, a kiln, and raised garden spaces.
