Squam Lake's water quality through time
Get PDFI am doing water quality research on Squam and Newfound Lake, to find whether the water quality is driven by local drivers or a bigger driver like climate. My hypothesis is that an outside the watershed factor, climate, is what is driving the water quality of Newfound and Squam Lakes. If this is true, the two lakes will go through the same changes such as algal blooms around the same time. If not, then there will be different patterns in the water chemistry and diatoms due to local factors. I will be collecting water samples for water chemistry analysis and collecting diatoms for diatom identification. These lakes are in separate watersheds so, if their water quality is driven by local factors theses should have different water quality chemistry and diatoms. This project is the primary step of the project before analyzing both Squam and Newfound Lakes. This step included taking water samples for water chemistry, analyzing diatoms in a sediment core from Squam Lake from 2014 to learn about the past water quality. Also, analyzing diatoms from a pond that was under eutrophication to compare the diatoms to see if Squam Lake has been through eutrophication in the past.Student Showcase of Research & Engagement Spring 201

SDS and recollections of a '60s radical
Get PDFDuring the 1960s in Denver, Colorado, Gary McCool was an activist in the civil rights movement and especially in the anti-Vietnam War movement. His activism developed out of a growing awareness of the injustices in the country at the time and was largely centered on the Vietnam War. As a graduate student in History at the University of Denver, Gary and a doctoral student at DU formed a campus chapter of the New Left student group Students for a Democratic Society (SDS). In this presentation, Gary will discuss the roots of SDS, the influence of its founding document – the Port Huron Statement – and a particular anti-war protest at DU in 1966 involving then Secretary of State Dean Rusk.Presentation
Wild brook trout (Salvelinus fontinalis) demographics and movement in the presence of undersized road crossings in headwater streams in central New Hampshire
Get PDFElectronic Thesis or DissertationPopulations of wild Brook Trout (Salvelinus fontinalis) continue to decline across their historic range, making relatively healthy populations and intact habitats within northern New England increasingly important for conservation. The Beebe River watershed, located in central New Hampshire, is home to intact headwater populations of wild Brook Trout despite movement barriers and riparian manipulation affecting tributaries to the mainstem river. The region has also experienced two centuries of widespread timber harvest and a century of stream acidification, creating further ecological stressors. We focused on three headwater tributaries with 1) impassable road crossing and reduced canopy cover, 2) passable road crossing and reduced canopy cover, and 3) no impediments to movement and unaltered canopy. We documented Brook Trout abundance, density, age structure, condition, biomass, growth, net movement, cumulative movement, home range, and recruitment with the goal of better understanding potential habitat influences on fish across tributaries and among geomorphic threshold regions. Our primary sampling methods included depletion electrofishing, PIT tag mark-recapture techniques, and detailed habitat assessments and temperature monitoring. We hypothesized that undersized crossings and no-low canopy reaches would create physical and thermal barriers for fish. In particular, we predicted that fish in streams with these barriers would exhibit lower density, fewer age classes and lower growth rates while seasonal and annual movement would increase compared to fish in an unimpacted stream. Overall, tributary populations were comprised of young fish that exhibited little movement. We failed to support many of our hypothesis metrics due to underestimating the indirect influences of no-low canopy reaches. Although we documented a crossing barrier inhibiting upstream movement, fish with unrestricted access to the no-low canopy primarily grew more and moved less, while density remained stable interannually. In contrast, fish in the most impacted stream and the unimpacted stream exhibited increased movement and significant declines in interannual density. This project was a unique opportunity to compile a detailed description of the spatial and temporal differences in Brook trout populations for two seasons prior to multiple crossing replacements and habitat enhancement. Our research helps fisheries managers to better understand the benefit of watershed-wide restoration to inform the protection of wild Brook Trout populations
Effects of foam rolling on aerobic performance
Get PDFPhysical activity causes microtrauma, fascial scar tissue, and other muscle damage leading to delayed onset muscle soreness (DOMS). Foam rolling (FR) has been shown to be an effective cool down technique to reduce DOMS. Currently, there is no research regarding the use of FR as a warm-up for aerobic training. PURPOSE: The purpose of the study was to examine the effect of various warm-up techniques on aerobic performance in Division III soccer players. METHODS: Seven male and nine female Division III soccer players completed the study. Baseline measurements of each participant were taken including height, weight, and body composition. Participants performed the Multistage Fitness Test three times with 1 week in between trials. Before each test, participants completed a warm-up of either FR, dynamic stretching (DS), or a combination of both (FR/DS). RESULTS: There was no significant difference in VO2max between the warm-up techniques (FR: 44.44 ± 5.11 mL/kg/min, DS: 43.34 ± 4.84 mL/kg/min, FR/DS: 43.91 ± 5.10 mL/kg/min). CONCLUSION: FR or FR/DS can be as effective as DS when used for a warm-up prior to aerobic performance.Student Showcase of Research & Engagement Spring 201
Analysis of water vapor transport and precipitation over the Russian River and Santa Ana River watersheds in California.
Get PDFCalifornia water resources are heavily dependent on the precipitation associated with atmospheric rivers (ARs). This study is a 20-yr cool season (October-March) climatology that examines the vertical distribution of (IVT) in ARs over the Russian River (RRW) and Santa Ana River Watersheds (SARW). Cool-season precipitation data from PRISM is averaged over the RRW and SARW for the 20-year period 1999-2019. IVT magnitude and direction are calculated using water vapor flux and wind data from NASA MERRA in 50-hPa layers at 38°N 123.125°W for the RRW and 33°N 117.125°W for the SARW. AR events with IVT magnitudes greater than 250 kg m-1s-1(IVT250 events) in the RRW generate up to ~70% of total annual precipitation and generate up to ~60% of total annual precipitation in the SARW. The vertical structure of IVT250 events is analyzed to investigate the distribution of water vapor flux in the lower troposphere (1000-700 hPa), the upper troposphere (700-300-hPa), the direction of IVT relative to terrain, and precipitation totals. IVT concentrated in the 1000-700-hPa layer, and southwesterly ARs explains 73% of the variance of precipitation totals in the RRW and 48% of the variance in the SARW.Student Showcase of Research & Engagement Fall 201
Chemosensory behavior and temperature preferences of northern crayfish (Faxonius virilis) and rusty crayfish (Faxonius rusticus)
Get PDFElectronic Thesis or DissertationInvasive crayfish can alter aspects of the behavior of native crayfish with consequences that are yet to be fully understood. Crayfish respond to water temperature and chemosensory cues as they navigate, forage, find mates, and encounter predators. Given the disruptive effects invasive species can directly have on native species, it is important to also establish how cues from non-native species may affect the sensory landscape and alter behavior of native species even in the absence of physical contact. We collected a resident species in New Hampshire, the northern crayfish (Faxonius virilis), and quantified the effects of cues (alarm substances and physical presence) from the non-native rusty crayfish (Faxonius rusticus) on its activity. We also quantified the temperature preferences of both species and tested for any interactive effects of temperature and rusty crayfish cues on the behavior of northern crayfish. We found that these two species differed in their temperature preference, with northern crayfish preferring a warmer temperature than the rusty crayfish. The alarm cue from rusty crayfish altered the behavior of northern crayfish, inducing them to move more slowly. We also found that temperature affected how northern crayfish reacted to rusty crayfish cues in terms of movement distance. Our findings suggest that chemosensory cues from non-native crayfish may have an effect on resident species during an invasion process. Future investigation into population- and region- specific chemosensory-induced behavioral changes in native crayfish species is warranted
Teachers' tales go online: digitizing oral histories on cassettes
Get PDFFor a time beginning in the 1970s, cassette tapes were very popular for recording oral histories. Today, these cassettes have exceeded their expected lifespan. Photographs, newspapers, and yearbooks fill many online repositories, but libraries and archives may find themselves wondering how to digitize an audio collection. This article presents a case study of one librarian's effort to run a pilot digitization project for twenty-one oral history cassettes.Article
Hydrometeorological characteristics of ice jams on the Pemigewasset River in central New Hampshire
Get PDFIce jams that occurred on the Pemigewasset River in central New Hampshire on 26 February 2017 and 13 January 2018 resulted in significant localized flooding in the towns of Plymouth and Holderness. The precipitation events that preceded these floods occurred in association with regions of enhanced moisture and moisture transport known as atmospheric rivers (ARs). ARs are well known to be responsible for wintertime extreme precipitation events, flooding, and variability in annual precipitation on the U.S. West Coast, while their association with extreme precipitation and flood events on the U.S. East Coast is less understood. The role of ARs in flooding associated with ice jams is likely complicated by frozen soils, snow cover, and river ice during the winter, which all can influence the hydrologic response to wintertime liquid precipitation. The goal of this paper is to investigate the hydrometeorological characteristics preceding 20 ice jams on the Pemigewasset River in central New Hampshire and identify the possible role of ARs. The February 2017 and January 2018 events represent two case studies characterized by different antecedent conditions that ultimately yielded the same result. The February 2017 event featured a “long melting period with low precipitation” scenario, with several days of very warm (5°–20°C) daytime temperatures that resulted in xiii extensive snow melt followed by short-duration, weak AR-associated rainfall ~10–15 mm during a 6-h period immediately prior to the formation of the ice jam. The January 2018 event featured a “short melting period with high precipitation” scenario with snow melt that occurred primarily during a more intense and long-duration AR that resulted in >50 mm of rainfall during a 30-h period. Composite analysis of 20 ice jam events support the linkage of these events to ARs: 19 of 20 events were preceded by integrated vapor transport (IVT) magnitudes >250 kg m−1 s−1 in the 2 days prior to the ice jam date and are associated with a composite corridor of enhanced integrated water vapor >25 mm collocated with IVT magnitudes >600 kg m−1 s−1 extending poleward along the U.S. East Coast.Electronic Thesis or Dissertatio
