Vista Wellness: An Educational Community Center for the Glenview Preserve

Fri, 12/14/2018 - 23:29
Abstract: The Glenview Preserve is home to a beautiful open vista of the High Peaks. This land was recently purchased by the Adirondack Land Trust and is looking for ways to sustainably manage the property by utilizing Paul Smith’s College capstone students for recommendations. One viable opportunity the ALT can incorporate, is the addition of a sustainable forum and conference center. With a community-oriented mind, Vista Wellness will provide a multitude of spaces for businesses and individuals to retreat while partaking in recreational activities. Vista Wellness is designed to be low impact with features such as a living roof and LEED certification. Using a promotional commercial and an intricate model, using state of the art construction supplies, we are able to convey the need for this addition to the Glenview property.

Influence of Slope on Soil Organic Carbon on Costa Rican Coffee Farms.

Mon, 05/07/2018 - 10:21
Abstract: Soil management is an important factor on agroforestry farms that help with soil fertility and carbon storage. Coffee agroforestry farms in Central Valley Atenas, Costa Rica were analyzed between November 2008 and May 2017. The objective of this study was to see if there is a relationship between mean slope and annual soil organic carbon sequestration (Mg/ha), and mean slope and soil organic carbon storage (Mg/ha), from samples taken on November 2008/May 2009 and November2016/ May 2017. Sample were taken on five farms with twenty 0.05 ha plots. Many coffee farms in the central valley are assembled on steep slopes or sides of mountains. Steep slopes are susceptible to erosion affecting the amount of soil organic carbon sequestration and storage. There was not a significant relationship found between mean slope and loss of carbon sequestration annually in November 2016/ May 2017 (Mg/ha). Mean slope and soil organic carbon storage from November 2016/May 2017 were compared by testing the effects of slope with carbon storage and there was no relationship. Whereas a statistically significant positive relationship was found between mean slope and soil organic carbon storage from November 2008/ May 2009. Additional data was examined to look at annual carbon sequestration loss on conventional and organic farms. However there was not a significant difference between the two. When all farms were compared for their annual carbon sequestration loss, marginally significant difference was found, but reasons for these differences remain a hypothesis. Further research to examine these differences may include practices of the farmers and erosion steeper slopes before erosion implications were taken by the farmers.

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.

Special Topic: An Investigation of Long Term Monitoring of Fishes in Two Aquatic Ecosystems

Fri, 05/11/2018 - 10:06
Abstract: Lower St. Regis Lake Abstract Long-term ecological research is important in understanding how fish communities change over time. The objective of this study was to determine how fish communities in Lower St. Regis Lake have changed. From 2004 - 2017 fisheries students at Paul Smith’s College have conducted lake surveys on Lower St. Regis Lake using standardized sampling protocols. This study showed shifts in fish community composition, changes in size structure, and variable body condition. As Lower St. Regis Lake changes, continued long-term ecological research will provide an opportunity for students monitor and study factors that may be effecting fish populations and communities. Smitty Creek Abstract Long term ecological monitoring of streams provides an effective means to evaluate changing habitat conditions on fish population dynamics. Our objective was to use long-term data from four tributaries in Smitty Creek Watershed to explore the relationship of age-0 brook trout densities to regional weather conditions. Catch data of age 0 brook trout was collected during the fall from 2004 to 2017. Average monthly precipitation and temperature data was taken from the Lake Clear regional weather station. Of four streams, Little Aldo showed correlation of age-0 brook trout with the precipitation and temperature data. Future work should include improved instrumentation within the reaches and the use of site-specific data.

Management Plan to Increase Nesting Success of Northern Pintails (Anas acuta) in the Prairie Pothole Region of North Dakota

Mon, 05/07/2018 - 17:36
Abstract: Once one of the most abundant ducks in North America, northern pintails have significantly declined since the 1960s when populations reached about 10 million. Over the past 40 years they have declined 78%, or about 2.4% per year between 1966 and 2015, due to expanding agricultural activity in their prairie pothole breeding grounds. In 2009 that the pintail population was estimated at 3.2 million, which is substantially below the 5.6 million population goal set by the North American Waterfowl Management Plan. The northern pintail population is substantially impacted by drought; and a loss of grasslands and wetland habitat in the prairie pothole region. Without proper breeding habitat pintails migrate further north to the Artic lowland tundra, where wetland conditions are more stable. However, when large numbers breed in these regions fewer young are produced. As a result, the prairies are where the fate of the pintail population lies. Throughout North America the northern pintail is listed as a migratory bird species where it is protected under the Migratory Bird Treaty Act and receives some management under the North American Waterfowl Management Plan. In North Dakota, the northern pintail is listed as a level II species of concern and there it receives management under the State Wildlife Action Plan, but because it is only a level II species it does not receive the management until all actions are covered for level I species. However, due to the species large geographic range and large worldwide population estimate it is listed as a species of Least Concern with a declining population on the International Union for Conservation of Species (IUCN) Red List of threatened species. The goals of this plan are to increase the abundance and distribution of northern pintails in North Dakota over the next 10 years and to provide information that leads to greater public involvement for the management of the species in North Dakota. The objectives to achieve these goals include: mitigation of agricultural impacts on nests, reductions of egg, hatchling, and hen predation via predator exclusion, increase in nesting habitat via Farm Bill practices and State Wildlife Grants, and the education of the public about the nesting requirements of northern pintails and the potential impacts of agriculture as well management practices to avoid these impacts. Based on population modeling, egg, hatchling, and hen survival is the key factor to focus on when managing for this species. An increase of about 50% nest success (eggs) and reduced predation rate on hatchlings and hens should result in a positive population trend, yielding a population of 6.7 million in 10 years, with a greater than 50% increase being more favorable to the overall goals and objectives. Northern pintails are a game species that needs management action in breeding areas to ensure their survival and growth for the enjoyment of current and future generations.

Management Plan to Increase King Rail (Rallus elegans) Populations in the Northeastern United States (2019-2034)

Fri, 05/04/2018 - 19:00
Abstract: King rails (Rallus elegans) live in freshwater marshlands and rice field habitats. These habitats are often associated with food sources and nesting cover. Diet consists of 58% animal matter ranging from small crustaceans to fish and frogs. Nests are placed in large clumps of grass throughout dense vegetation, or in a tussock. Outside the nesting and breeding season, rails found in the northeastern United States migrate south in search of food opportunities. With only 10% of natural wetlands remaining from destruction and alterations in farming techniques, major threats associated with king rail populations have rose. King rails are listed as near threatened throughout the United States and under no protection aside from the Migratory Bird Act. The IUCN Red List reported that the current population trend is decreasing at rate of 30% over 14 years. Based on population models, survival within the fledgling stage is the key factor to focus on during conservation practices. The goal of this plan is to increase the population from its current state to a sustainable level for maximum viewing and ecological stability throughout the northeastern states of Maryland, Delaware and New Jersey within the next 15 years. The objectives to reach this goal include: find population estimates to better assess the species abundance of king rails, obtain lands for king rails species to inhabit, decrease the amount of selected marshland being restructured, and increase the fledgling stage survival rate of king rails. King rails are an understudied species that deserve conservation help to ensure survival.

Rock Pigeons of Portland, Oregon: 10 Year Management Plan (2018-2028)

Thu, 05/03/2018 - 12:56
Abstract: Rock pigeons (Columba livia) of the family Columbidae are urban exploiters with a worldwide distribution. Pigeons commonly present a management issue in urban areas due to their high density and opportunistic feeding habits. Rock pigeons are not protected under the Migratory Bird Treaty Act as they are non-migratory however, their versatile nature as wild, feral, and domestic stock tends to lead to their exclusion from hunting seasons and similar legislation. Property damage caused by pigeons in Portland is intensified in areas where the birds roost such as the site of a deconstruction grant program where roosting pigeons caused irreparable damage to over 66% of previously recoverable siding material. The view of pigeons as a nuisance by residents and the potential for disease transmission to people add to human-pigeon conflict within Portland. At its current trajectory, the rock pigeon population of Portland, Oregon will continue to rise above the social carrying capacity until it reaches the biological caring capacity. The goal of this management plan is to reduce human-pigeon conflict in Portland, Oregon. This goal requires a reduction in the population size of pigeons in the city, a reduction in pigeon related damages to public and private property, a decrease in disease transmission potential of the pigeon population, and offering a controlled opportunity for human pigeon interaction.

Managing Raccoons (Procyon lotor) to Benefit Allegheny Woodrats (Neotoma magister) in New York, New Jersey, and Pennsylvania.

Thu, 05/03/2018 - 10:45
Abstract: Raccoons (Procyon lotor) are a generalist species whose populations are on the rise throughout the United States. Raccoons are well known for carrying rabies, mange, and many other diseases that can be transmitted to other species. However, it’s the lesser known raccoon round worm (Baylisascaris procyonis) that is having a dramatic effect in the Northeastern United States. The adult worms reside in the small intestine of the raccoon and the eggs are passed in its feces which is then transferred to a new host. The round worms are not fatal to raccoons but can be to other species. One of those species, the Allegheny woodrat (Neotoma magister) collects the feces of other animals to eat the seeds out of it, meaning when they collect raccoon feces they are susceptible to contracting raccoon round worm. The Alleghany woodrat is endangered in New York state and threatened in New Jersey (Sheldon 2004). Therefore, it has become necessary to manage raccoons, the host of the round worm, in a way that will benefit the Allegheny wood rat. This includes decreasing raccoon populations, deworming raccoons, and getting the public more involved with the management of raccoons. If all of this were completed then the Allegheny wood rat would be much more stable and possibly able to recolonize the habitat it’s been extirpated from.
