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.

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.

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).

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.

Monitoring the Zebra Mussel Invasion Front: Use of New Technology

Thu, 02/09/2012 - 15:39
Abstract: Zebra mussels are invasive mollusks that are affecting the well-being of the water bodies in the United States. This study uses environmental DNA (eDNA) is a sensitive early detection system that may be useful in monitoring their spread. The purpose of this study is to determine the effectiveness of eDNA technology in identifying infested water bodies, to determine if zebra mussel DNA is in the Adirondack water bodies not known to be infested, if the water chemistry of these water bodies is favorable for zebra mussel establishment, and if the eDNA technology is transferable to an institution like Paul Smith’s College. Eighteen lakes, all in New York State were sampled, fifteen of which are located in the Adirondack Park. DNA was extracted from water and plankton samples and species specific primers were used for PCR amplification to determine if zebra mussel DNA was present. Of seven samples taken from sites known to be infested, five of these tested positive for zebra mussel eDNA. Four lakes not known to be infested within the Park also tested positive for zebra mussel eDNA. Based on zebra mussel risk parameters (water chemistry) applied to 1,469 Adirondack water bodies, less than 3% are at risk of zebra mussel establishment. However it is possible that established populations could occur at microsites that may have locally high levels of calcium and higher pH.

Promoting Conservation of Biodiversity in the Adirondack Park Through Understanding and Engaging Stakeholders

Thu, 02/09/2012 - 11:31
Abstract: Anthropogenic disturbance of natural environments has led to the widespread loss of native biodiversity and degradation of ecosystems. It is increasingly recognized that addressing this “biodiversity crisis” entails understanding the societal drivers of unsustainable patterns of use. Conservation psychology is a new discipline that specifically focuses on understanding the linkages between human behavior and action and promoting a healthy and sustainable relationship between humans and nature. In this project, we employed principles of conservation psychology with the goal of improving the efficacy and efficiency of conservation of biodiversity in the Adirondack Park (AP). To meet this goal we employed three specific strategies. The first of these strategies was the use of surveys to assess the values, attitudes, and actions different stakeholders have in regards to conservation of biodiversity in the AP. These surveys were disseminated via both direct mailings and online, and included 30 questions. Our second strategy was to use discourse analysis to create a dictionary of terms and phrases employed in a positive, neutral, and negative light in regard to conservation of biodiversity. This entailed analysis of 30 emic accounts derived from opinion articles written by stakeholders in the AP, as well as analysis of a number of etic accounts drawn from online sources. Our third strategy was to use conservation psychology literature to assess ways in which the presentation of information and peer-dynamics influenced the responses of stakeholders towards conservation of biodiversity. Using the combination of these three strategies, we were able to provide a holistic understanding of how different stakeholders in the AP perceive and act towards biodiversity conservation; identify language that can be used to illicit a more positive response from these stakeholders; and identify specific tools based on principles of psychology that can encourage more active and effective engagement in conservation of biodiversity by different stakeholders. Our research findings will allow groups focusing on promoting conservation of biodiversity in the AP to be more effective and efficient in their work in the future.

Assessment of Anion Retention within Variable-Charged Eastern-Central Adirondack Forest Sub-Soils

Mon, 12/05/2011 - 10:20
Abstract: Anthropogenic influences such as acid deposition and road salting have caused shifts in both the pools and fluxes of nutrients within Earth’s biogeochemical cycles. The mobility of ions within forest soils is a very well documented concept; however the significant mechanisms affecting these patterns are poorly understood. One mechanism affecting anion retention is the electrostatic attraction to soil colloid surfaces, which is poorly documented in the Adirondack Park. Soils were sampled from both glacial till and outwash sites with predominantly deciduous canopies. The amount of anion retention was documented through multiple soil ion extractions over a pH gradient from 2 to 9. A loss on ignition procedure was used to understand the relationship between both organic matter or Fe/Al oxides and the overall soil surface charge. The estimated retention of Cl- and NO3- is 252 Kg/Ha and 440 Kg/Ha, respectively. Using hypothetical watersheds, we calculated that it will take 14 years to saturate the subsoil with NO3- and only 7 years to saturate with Cl-. These results suggest that the effects of acid deposition may be seen up to 14 years even after deposition has ceased. The relatively limited retention of Cl- however, may explain increased salinization of freshwater ecosystems.

High Ruffed Grouse (Bonasa umbellus) Relative Abundance in a Transitional, Early-Successional Habitat

Mon, 12/05/2011 - 10:34
Abstract: Abstract I recorded and examined ruffed grouse (Bonasa umbellus) flush data across upland hardwoods, lowland coniferous, and transitional habitats within the Adirondack State Park, New York. The flush data was recorded throughout September, 2011. Study site areas were accounted for to establish a flush per hectare rate. Contrary to my hypothesis the transitional habitat produced significantly more flushes (x2, p<0.0001) than the hardwoods and coniferous habitats. Lowland (conifer + transitional) and upland flush per hour rates were compared to a mean central Adirondack rate. I was unable to establish a significant conclusion from this comparison. A habitat suitability index indicated that stem density and the absence of aspen (Populus tremuloides, Populus gradidentata) appeared to be the limiting factors within the hardwoods habitat. Unanimous upland stem density suitability index values (SIV3) of zero resulted in an upland fall to spring cover value (FSCOV) of zero. If stem density was suitable throughout the upland habitat the quality of grouse cover would have increased significantly (FSCOV=0.9). However, aspen would have to be established to create quality grouse habitat with adequate cover and forage. Therefore, I concluded that as the upland forest stand ages and stem density increases, grouse densities are also likely to increase.

Burrow characteristics, nest success, and chick productivity of the black guillemot (Cepphus grylle) on two islands in the Gulf of Maine.

Mon, 12/05/2011 - 13:54
Abstract: Knowledge of the black guillemot Cepphus grylle population, nesting habitat preference, nest success and chick growth in North America is limited as the majority of studies on this species have been conducted in other northern countries such as Ireland and Greenland. Petit Manan Island and Eastern Brothers Island (Gulf of Maine, ME) each offer unique black guillemot nesting habitat from each other. Petit Manan offers predominately debris-like habitat (driftwood, buoys, etc.) and Eastern Brothers offers traditional rock-cliff habitat. I investigated the influence of burrow characteristics on nest success and chick growth on both islands. Burrow measurements were particle size of nest substrate, nest depth, nest cup diameter, light penetration, and neighbor distance. Nest success was scored by number of eggs hatched and chick growth was measured through body mass indices (mass/wing chord). Nest cup diameters were significantly larger in debris than in rock burrows which were typically tight crevices. No other characteristics were statistically significant different between debris or rock burrows. Consequently, nest success and chick growth was not affected by type of burrow.

An analysis of social behavior in captive gray wolves and its effects on pack dynamics

Mon, 12/05/2011 - 17:55
Abstract: Animals live in groups for a variety of reasons, including access to certain prey items, defense of territory, and protection of resources. Canids have proved a popular subject for studies in social behavior, and many variables of behavior have been tested, providing an in-depth picture of how these animals typically live. Gray wolves (Canis lupus) in particular have been studied extensively throughout the years, both in the wild and in captivity. This study investigated social behaviors within a captive wolf pack so that an activity budget could be established with aid of an ethogram. A pack hierarchy was also established using tail positions as a guide, and behavior frequency was compared between each gender. Overall, resting behaviors were the most common for the pack under study, and most common for both males and females. This is likely because the study took place during the summer when temperatures were high and the animals didn’t expend much energy. Males and females did not show a significant difference in the proportion of time spent exhibiting each behavior (X2=1), likely because each sex plays a similar role in the pack. While play behaviors comprised only 12% of all recorded, I believe that social play is an important function for providing social cohesion and an outlet for aggression. Since there is still much to be understood about social play in adult wolves, I believe that it should be the focus of future studies. I also believe that this study can provide a framework for future investigations of a similar nature, and that such future studies should also attempt to draw comparisons between wild and captive wolf packs, as they differ in several respects.
