Cultural eutrophication of Lower Saint Regis Lake using diatoms and organic content as indicators of eutrophication.

Tue, 04/28/2020 - 12:06
Abstract: Cultural eutrophication can greatly affect water quality, leading to algae blooms and can affect fish communities. Throughout the history of Paul Smith’s Hotel and College, development along Lower St. Regis lake has led to increases in eutrophic conditions, which has detrimental effects on water quality. In this study, a sediment core from Lower St. Regis Lake was analyzed to determine when past eutrophication events occurred. This was accomplished using species counts of diatoms from every 1.0 cm of sediment. The relative abundance of diatom species such as Tabellaria flocculosa, Asterionella formosa, and Fragilaria crotonensis were used as indicators of more eutrophic conditions. Loss on ignition (LOI) was also used to measure the organic content in the sediment at increments of 0.5 cm. The higher percent lost on ignition indicates higher productivity in the lake and more eutrophic conditions. Some samples from the sediment core were also dated using lead-210 to create a timeline that could be compared to known dates of events occurring along the lake that could have affected the trophic status of Lower St. Regis Lake. There was a sudden spike in the relative abundance of F. crotonensis and an increase in organic content at a depth of 20 cm in the core, indicating that conditions became more eutrophic. Based on the lead-210 dates, this spike in F. crotonensis and organic content occurred between 1898 and 1908, when development around the lake was increasing and Paul Smith’s Hotel added indoor plumbing with poor wastewater treatment practices.

Fusion Confusion

Wed, 05/06/2020 - 10:27
Abstract: Fusion cuisine is confusing is a statement and a question. The question half of it is a double-edged answer. Fusion is in itself simple but, when applying it to food, the idea can get muddled. To fully understand the meaning of this we will have to take a deeper look at the history behind food itself. Afterall knowledge is to be built on a strong foundation, much like food.

Food Sustainability

Sun, 05/03/2020 - 22:50
Abstract: The purpose of my research was to find and use the various methods of food sustainability. That meant participating in the local farmers market and getting to know the community and sustainable practices. This research also gave me the chance to look at different cultures and practice of whole animal cooking, how they give back to their environment. This became more than just putting food on the plate, it's about how we get it there and what was done to accomplish that. What can we do in a modern era to keep sustainability alive and keep our stomachs full? Hopefully I was able to line out the few suggestions in my paper.

The Influence of Microtopography on the Spatial Distribution of Peatland Plants

Mon, 04/27/2020 - 13:01
Abstract: Microtopography in peatlands creates structural patterns within the environment that, if understood, could allow for more comprehensive wetland management and restoration plans to be constructed. The objectives of this study are to determine: 1) the spatial scale at which microtopography occurs on in Adirondack peatlands; 2) if hummock size changes in relation to the distance from the forested wetland edge; and 3) if individual plant species respond to, or vary, in relation to microtopography and abiotic factors. To determine the influence of microtopography on peatland plants, data were collected on the surface area and height distributions of hummocks, the distance between hummocks and the abiotic soil characteristics. Plant species richness, and percent cover data were collected on hummocks only. The spatial scale of microtopography was determined to be regularly distributed across the sampling area. There was no significant correlation between the distance from the coniferous-edge and the relative size of hummocks. Plant species richness was found to be higher on hummocks as opposed to hollows. Using a combination of correlation and multiple regression analysis we determined that leather leaf (Chamaedaphne calyculata), lowbush blueberry (Vaccinium angustifolium), and common cranberry (Vaccinium macrocarpa) were correlated to individual abiotic variables. The variability of the percent cover of leather leaf was explained by increasing surface area, lower soil temperatures, and lower pH; the variability of the percent cover of lowbush blueberry was explained by increasing oxidation-reduction potential (ORP) and lower pH; and the variability of the percent cover of common cranberry was explained by lower hummock height alone. Only three of the common plants identified were correlated with the abiotic variables measured. Further research should be done to continue to determine the primary influence of the elevational gradients on the plant species composition and to determine the resilience of these systems to changing climate.

Developing a Bird Integrity Index (BII) for Use as an Indicator of Stream Condition in the Northern Adirondack Park

Mon, 04/27/2020 - 12:50
Abstract: The primary goal of this research was to create a Bird Integrity Index (BII) to be used for the ecological integrity analysis of streams and their related riparian zones in the northern Adirondack Park based on frameworks provided by previous research in Oregon. Fifty-eight metrics were tested from avian survey (point count) data along fifteen stream reaches of 0.5km in length. These metrics represented aspects of avian taxonomic richness, dietary preferences, foraging techniques, tolerance or intolerance to human disturbance, and nesting strategies. To evaluate the responsiveness of each metric, they were plotted against an index of stream condition based on sampling of benthic macroinvertebrates according to the outline provided by the stream biomonitoring research unit of the New York State Department of Environmental Conservation. Five of the fifty-eight candidate metrics remained after removing metrics that had an R2 value of less than .2 or were highly correlated. Individual avian metric scores ranged from 0-10 and BII scores were set on a scale of 0-100. While the BII presented here was successful in responding to varying conditions based on disturbance levels (R2= .64), due to multiple unexpected relationships between avian metrics and stream condition, it is proposed that more in-depth and comparative research be completed before an Adirondack specific BII is presented for field usage.

south island kaka managment plan

Mon, 05/04/2020 - 22:29
Abstract: The south island kaka (Nestor meridionalis meridionalis) is a large olive brown parrot endemic to the low to mid elevation forests of New Zealand. Their historic range spanned all 3 large islands and many of the smaller offshore islands as well. Unfortunate in the past century human involvement has caused these birds to be listed by the IUCN. In 1988 they were listed as near threatened with a continual decreasing population leaving them as endanger with less than 1000 individuals left in the wild in 2019 with a thin fragmented forest prone to die back and full of invasive species. To combat this, we have come up with a management plan to restore a 1000 acre plot of land on Stewart Island west of Half Moon Bay where their historic population was estimated to be the most concentrated on the island. To do this we plan on removing invasive white-tailed deer by using the local hunters to decrease their population supplemented with contraceptive bait piles to decrease their fecundity. On this plot we will manage and monitor the growth of this forest to help it develop into an even aged stand that is less prone to die off and with high productivity that is suitable breeding ground for south island kaka. After 50 years of managing for native plant species and trapping and poisoning of invasive mammals such as stoats, rats and bush tailed possum most if not all invasive will be removed. We will then release 100 kaka into the management area. We will monitor their movement and use of the habitat to better protect them from invasive species in hope to increase their survival closer to their historical percentages (90%). Once this is accomplished we will continue to monitor the area until their population becomes stable and no sign of invasive mammals are impacting their survivability.

Ten Year Management Plan on Jaguar (Panthera onca) Populations in Brazil

Sun, 05/03/2020 - 11:27
Abstract: Jaguars (Panthera onca) are the world’s third largest big cat and are found throughout Latin America and small parts of the United States of America. They are solitary, elusive carnivores that serves an ecological role as a keystone species throughout their distribution by maintaining populations of herbivorous species which provides more habitat availability and suitability for other wildlife species. Their populations are going through a decline and now 173000 individuals are currently inhabiting about half of their historical range. The factors that endanger jaguar populations are habitat destruction, illegal hunting, and loss of prey. The increase in ranching and the need for more communities for the growing human population are the reasons for the continuation in habitat destruction and the confrontations between people and jaguars. The goal for this management plan is to increase the jaguar populations by 10-15% within 10 years and maintain the populations throughout the country of Brazil. There are currently 86,800 individual jaguars in Brazil and reaching the goals in maintain populations will require improving their habitat and prey availability while reducing the factors that are the direct cause in their decline. The objectives include focusing conservation efforts on certain age classes to increase the survivability of individuals and the chances of reproduction to add individuals to a population. They also include mitigating human and jaguar conflicts, making environmental protections and wildlife management a bigger priority in the public, politics, and laws, and reducing the rate of habitat fragmentation by 20% throughout the country of Brazil. Some actions to make these objectives successful include conducting further research on the life cycle and natural behaviors on jaguars to support conservation efforts needed to benefit the populations and continuing current methods that are used to reduce human and jaguar conflicts. To monitor the success and failures of this management plan, public surveys for the residents’ perspective on the jaguars will be conducted yearly along with some population counts on the jaguars in each region of Brazil. Jaguars are currently listed as near threatened by the International Union for Conservation of Nature (IUCN) red list and due to the population declines and the continuation of factors effecting the populations, they will mostly likely be listed as vulnerable in 30 years. If there is an increase in conservation efforts and a reduction in conflicts between jaguars and human communities, then the jaguars will have a smaller chance of reaching extinction.
