A Taste of Tea

Thu, 11/30/2017 - 14:49
Abstract: Originating in Southeast China, tea is one of the most consumed beverages in the world, second only to water with coffee in third. Though tea has many names, they all come from the same plant, Camellia sinensis. There’s white, yellow, green, oolong, pu-erh, and black or red tea; each has its own variants and processing methods to distinguish them. Tea has spread throughout the world and each culture took these leaves and made it their own in different ways. The journey it has taken is an interesting one with a lot of controversy, conflict, and corruption once introduced to the British Empire.

Does the presence of Malus spp. increase the fertility of the soil surface in pastures?

Mon, 05/01/2017 - 18:24
Abstract: Techniques to increase soil fertility in a pasture can benefit the system by combating soil degradation and increasing the health of vegetation. The use of apple trees (Malus spp.) may be particularly beneficial in achieving this due to reliable fruit yields, ease of management, and variety of suitable habitat. We hypothesized that soil directly under the canopy of apple trees would be higher in nutrients (C, Ca, K, Mg, N, & P) than soil in areas with no tree cover. Soil samples were taken from the top 15 cm of the soil surface under apple trees and in areas without trees at 14 sites in Massachusetts and New York. Samples were analyzed using spectrometry and color imagery to determine nutrient content. Potassium and magnesium concentrations were found to be significantly higher in under-canopy samples. Further research may expand these results and determine if the application of apple trees can be used to increase the health of pasture systems.

Comparison of Cyprinid Composition and Abundance in Relation to Microhabitat Characteristics within Heron Marsh, in the Adirondack Park, NY

Mon, 04/24/2017 - 15:47
Abstract: Cyprinids are susceptible to local, watershed, and regional extirpation within the United States. Habitat alterations, non-indigenous species introductions, changes in water quality, and anthropogenic barriers have resulted in a decrease in overall cyprinid biodiversity. The objectives of this study are (1) to establish baseline water quality characteristics among sites in summer and fall, 2016, (2) to compare minnow densities to percent macrophyte cover among trap sites for common species, and (3) to compare 2016 minnow densities by species and combined with 2014 and 2012 density estimates. Heron Marsh is a shallow marsh located with the Adirondack Park, NY, that supports a wide variety of fishes in the Cyprinidae family. Baseline water quality was collected using an YSI meter, cyprinid densities were estimated using galvanized steel minnow traps, and macrophyte cover data was estimated using a 21-point grid system for trap sites within the marsh. Water quality monitoring will help assess changes in the marsh over time due to global warming. More minnow trap sites must be established to determine if there is a relationship between macrophyte cover and cyprinid abundance. This will allow the statistical power of our tests to become robust to assumptions that were otherwise violated. Cyprinid biodiversity and abundance were highest amongst the upper region of the marsh for most years. This suggests that the upper region of the marsh may be a sanctuary or refuge for certain cyprinid species.

Wildlife Habitat Conservation and Management of Invasive North American Beavers (Castor canadensis) in Southern Patagonia from 2017-2037

Tue, 04/25/2017 - 13:40
Abstract: Importing the incisor-toothed ecosystem engineers from Canada to the southernmost tip of South America seemed like an innovative idea in 1946. Since this early introduction by the Argentine Navy, this species has grown exponentially (5,000 times their initial population) to 35,000 and 50,000 in Tierra del Fuego. Their density (0.2–5.8 colonies/km2) in this geographic region is even higher than North America (0.08-1-4 colonies/km2). North American beaver (Castor canadensis) are notorious hydrologists and modify their habitat to construct dams, canals, and dens. This species presents ecological, economical, and socio-cultural detriments. These factors have the potential to migrate to northern territories with the beaver due to climatic conditions favoring the species propagation. This population’s exponential growth is deemed larger than predicted due to the lag in local inhabitants noticing the rodents’ presence. To address beaver management, Chile and Argentina are working together under a bi-national agreement. Their goal is to restore Southern Patagonian ecosystems with total eradication of invasive beavers. The 2017-2037 Southern Patagonian Beaver Management Plan identifies the following goals: 1) Decrease the population of North American beavers (Castor canadensis) in S. Patagonia. 2) Define beaver-absent areas near invaded territories that have the potential to become occupied by this plastic species in the near future due to similar habitat criteria. 3) Education, information, and outreach on S. Patagonia beaver management is improved. 4) Zoonotic implications of beaver are monitored, investigated and managed. Objectives for each of these goals are included within the management plan. Wildlife biologists, trappers, and public input are essential to this management plan. Surveys issued to trappers and citizens aid in monitoring of zoonotic diseases related to beavers as well as determine public opinion of this species. Trapping will continue to be integral in beaver management.

Management Plan to Increase Gould’s Wild Turkey (Meleagris gallopavo mexicana) Population in New Mexico

Wed, 04/26/2017 - 20:57
Abstract: Gould’s wild turkeys (Meleagris gallopavo mexicana) are the largest subspecies of wild turkey in United States, but are also the most geographically restricted. In New Mexico, Gould’s populations occur in the Peloncillo, Animas and San Luis mountain ranges located in Hidalgo County, southwest New Mexico. This subspecies faces threats of habitat loss by several factors that including severe wildfires, competition with livestock grazing, lack of sustaining water sources. Gould’s wild turkeys are a popular United States subspecies for avid hunters seeking the completion of the Royal or Grand Slam wild turkey hunts. With the proper management, New Mexico could provide an increase of habitat for the Gould’s wild turkey. The overall goal of this management plan is to increase and maintain the Gould’s wild turkey population in southwest New Mexico to maximize hunting and recreational viewing opportunities. Objectives to be taken to achieve this goal includes: 1. Improvement and maintain the occupied and potential turkey habitat in their native range within 10 years. 2. Obtain suitable habitats through conservation easements within 5 years. 3. Increase and maintain a sustainable population within 10 years. 4. Gain landowner and volunteer participation through outreach and funding through partnerships with organizations within 10 years. The increase of Gould’s wild turkey populations will positively affect hunting and viewing opportunities and economics from higher populations of Gould’s wild turkey. This management plan will be implemented for the next 10 years, starting in 2018 and ending in 2028. Once this plan is complete, we will then assess the actions and implement further management needs for the future.

Preventing the Spread of Eurasian Boar (Sus scrofa) into New York State

Thu, 04/27/2017 - 09:28
Abstract: Eurasian boars (Sus scrofa) pose a large threat as they are destructive in their feeding habits. According to the USDA, roughly 5 million wild Eurasian boar live inside the United States, and are currently found in 31 states. This species is responsible for $1.5 billion dollars in crop destruction, property damage, and management efforts annually. Eurasian boars are an exotic invasive species originating from Eurasia, and were introduced to the United States during the 1500s for meat and hunting purposes. This species survives and successfully breeds in a large range of habitats, and outcompete native fauna. The goal of this management plan is to prevent Eurasian boar populations from becoming established in New York State. Preventing the spread of this species is important because they are not native to New York, and can become an economic burden to farmers and local residents. There is currently no known breeding populations inside of New York, but Eurasian boars have come into New York in the past and are likely to return. The following objectives will be enacted to achieve the overall goal for preventing the spread of this species: (1) Educate the public on the dangers and negative impacts from Eurasian boars (2) Update and maintain current legal policies that prevent the importation, sale, trade, or ownership of Eurasian boar (3) Establish response teams that would eradicate wild Eurasian boar populations. This management plan will be implemented for the next 10 years (2017-2027). Once completed, the successfulness of this management plan will be reviewed and reassessed.

Recovery Plan for the Wood Turtle (Glyptemys insculpta) in Connecticut

Thu, 04/27/2017 - 10:16
Abstract: Since European colonization began in North America, turtle populations have declined across the entire continent, due to habitat conversion and overharvesting. Wood turtles (Glyptemys insculpta) are medium-sized freshwater turtles, and the most terrestrial of North American turtles, though they still require year-round flowing streams. They are found throughout southern Canada, the Great Lakes region, and the northeastern United States south to Virginia. Wild adults attain sexual maturity at 10-14 and have been known to reach 50 years of age. Their populations have survived the impacts of human development until recent history, when automobiles and the expansion of road systems caused far greater adult mortality. This species is considered rare, but widespread, and is threatened with extinction due to small local population size, and components of their life history strategy. Like many turtles, wood turtle populations exhibit a Type 3 survivorship curve, with high nest and hatchling mortality, and low adult mortality. Their small disjunct breeding populations experience unnaturally high adult mortality from road crossings, illegal collection, agricultural mortality, subsidized depredation, and possibly forestry and dam practices. These problems are compounded by a lack of information regarding the species’s ecology. Currently there is no accurate population estimate, though the Canadian government estimates near or above 10,000 individuals range-wide. The focus of current management is to promote the survivorship of adult wood turtles, since adult survivorship is more essential to healthy populations than that of nests or juveniles. Emphasis is placed on reducing mortality from road crossings through fencing and underpasses, and reducing illegal collection. In areas where human development is less, collection may be the only serious threat. This management plan presents a comprehensive research plan that focuses on understanding the ecology of wood turtles, and outlines adaptive management strategies to increase survivorship. The goal of this plan is to ensure that a comprehensive and adaptive strategy is in place to reestablish the long-term stability of wood turtle populations in Connecticut.

Management Plan for Red-throated loons (Gavia stellata) in North America

Thu, 04/27/2017 - 10:44
Abstract: Red-throated loons (Gavia stellata) are an indicator species for aquatic ecosystems and environmental impacts. Although red-throated loons are listed as a species of least concern, their population is overall declining and not much is understood as to why this is occurring. Their population in Europe, Asia, and Russia are declining, but the North American population has remained stable for the last 40 years. From 1977-1993, the red-throated loon population in Alaska declined by 53% due to the 1985 T/V Exxon oil spill in the North Pacific Ocean. The current issue with red-throated loons is that there is no current data on their behavior, demographics and environmental threats, which makes it difficult to determine what best management practices are needed in order to maintain their population in North America. This management plan is designed to maintain the stable red-throated loon population, increase the understanding of their behavior, increase the public awareness on their ecological role, and monitor environmental impacts that affect red-throated loons for duration of 10 years. This will be done through a series of objectives such as: increasing first year survival rates and nesting success; maintaining the annual adult survival rate at its current rate; educating fish market industries, oil and gas industries, and the general public on the ecological role of red-throated loons; conducting behavioral studies and monitoring concentrations of contaminants that affect red-throated loons.

Management plan for the rusty patched bumble bee (Bombus affinis) in Indiana (2017-2027)

Thu, 04/27/2017 - 11:30
Abstract: The rusty patched bumble bee (Bombus affinis) used to be widely distributed throughout much of the Midwest and Northeast United States. However, B. affinis has experienced precipitous declines over the last two decades in part due to habitat loss, climate change, pathogens, and agricultural pesticides. Loss of crop pollination by insect pollinators like B. affinis, which supports large portions of our agricultural industry, presents an imminent threat to our economy and culture by reducing the diversity and security of crops produced nationally. Because recent political turmoil obfuscates federal responses to wildlife conservation, including enforcing the recently acquired endangered species status of B. affinis, state-level management plans may become integral for protecting endangered species. The state of Indiana has historically had large populations of B. affinis and is one of few states with such historical populations that also have counties with documented occurrences of B. affinis between 2000 and 2015. This management plan aims to stabilize B. affinis populations in the state of Indiana by 2027. Surveys will determine the extent to which B. affinis occur in counties with recent occurrence records by 2020, and long-term studies will aim to inform adaptive aspects of the plan and bridge gaps in knowledge about the ecology of B. affinis by 2027. Habitat management is addressed through creation or maintenance of spatially and temporally diverse floral resources by 2027 that will bolster the ability of queens to found colonies, and for colonies to produce more workers and queens throughout their whole cycle. Lastly, the lead state agency will propose legislation that bans the use of harmful neonicotinoids statewide by 2022 in order to increase queen reproductive success. The rusty patched bumble bee represents a culturally and financially significant species of conservation concern; this management plan details state-level actions that will stabilize B. affinis populations by 2027 independent of federal action.

Management Plan for Saker Falcons (Falco cherrug) in Ukraine

Thu, 04/27/2017 - 11:31
Abstract: The Saker falcon (Falco cherrug) is a critical species in Ukraine’s dry grassland ecosystem. It is a large falcon that varies in coloration, ranging from dark brown to a light cream color. It is sexually dimorphic only by size, with the female being larger than the male. This falcon preys primarily on small mammals and medium-sized game birds within the grassland ecosystem. This raptor species was nearly extirpated from Ukraine due to heavy pesticide use and nest robbing. At the beginning of the 20th century an estimated 120-140 pairs of Saker falcons resided in Ukraine. The population has increased slowly since protection was enacted in 2001, and in 2010 the population reached 400 estimated pairs. The population has remained steady since it reached this level. However, the Saker falcon still remains endangered in Ukraine. The current threats of the Saker falcons in Ukraine include lack of nesting habitat, which prevents population from increasing, loss of grassland habitat for hunting, and a lowered availability of prey species such as the European ground squirrel (Spermophilus citellus). Prey availability has decreased due to loss of grassland habitat. This management plan outlines actions to increase the Saker falcon population by 70% from 2018 to 2038. This will be accomplished by increasing nesting habitat, improving grassland habitat in order to increase the European ground squirrel population, and enacting polices that will regulate the illegal taking of eyesses (a young bird taken from the nest before it has fledged) and wild juvenile Saker falcons for use in falconry. The projected population increase from these actions will allow for the delisting of Saker falcons in Ukraine by 2038.
