Field Test Of A Remote Multi-Path Clads Methane Sensor, Genevieve Plant, Michal Nikodem, Phil Mulhall, Ruth K. Varner, David Sonnenfroh, Gerard Wysocki

Faculty Publications

Existing technologies for quantifying methane emissions are often limited to single point sensors, making large area environmental observations challenging. We demonstrate the operation of a remote, multi-path system using Chirped Laser Dispersion Spectroscopy (CLaDS) for quantification of atmospheric methane concentrations over extended areas, a technology that shows potential for monitoring emissions from wetlands.

Long-Term Trends Of Changes In Pine And Oak Foliar Nitrogen Metabolism In Response To Chronic Nitrogen Amendments At Harvard Forest, Ma, Rakesh Minocha, Swathi A. Turlapati, Stephanie Long, William H. Mcdowell, Subhash C. Minocha

New Hampshire Agricultural Experiment Station Publications

We evaluated the long-term (1995–2008) trends in foliar and sapwood metabolism, soil solution chemistry and tree mortality rates in response to chronic nitrogen (N) additions to pine and hardwood stands at the Harvard Forest Long Term Ecological Research (LTER) site. Common stress-related metabolites like polyamines (PAs), free amino acids (AAs) and inorganic elements were analyzed for control, low N (LN, 50 kg NH4NO3 ha−1 year−1) and high N (HN, 150 kg NH4NO3 ha−1 year−1) treatments. In the pine stands, partitioning of excess N into foliar PAs and AAs increased with both N treatments until 2002. By 2005, several of these …

Urban Evolution: The Role Of Water, Sujay S. Kaushal, William H. Mcdowell, Wilfred M. Wollheim, Tamara A. Newcomer Johnson, Paul M. Mayer, Kenneth T. Belt, Michael J. Pennino

Faculty Publications

The structure, function, and services of urban ecosystems evolve over time scales from seconds to centuries as Earth’s population grows, infrastructure ages, and sociopolitical values alter them. In order to systematically study changes over time, the concept of “urban evolution” was proposed. It allows urban planning, management, and restoration to move beyond reactive management to predictive management based on past observations of consistent patterns. Here, we define and review a glossary of core concepts for studying urban evolution, which includes the mechanisms of urban selective pressure and urban adaptation. Urban selective pressure is an environmental or societal driver contributing to …

Genome Sequence And Comparative Analysis Of A Putative Entomopathogenic Serratia Isolated From Caenorhabditis Briggsae, Feseha Abebe-Akele, Louis S. Tisa, Vaughn S. Cooper, Philip J. Hatcher, Eyualem Abebe, William Kelley Thomas

New Hampshire Agricultural Experiment Station Publications

Background: Entomopathogenic associations between nematodes in the genera Steinernema and Heterorhabdus with their cognate bacteria from the bacterial genera Xenorhabdus and Photorhabdus, respectively, are extensively studied for their potential as biological control agents against invasive insect species. These two highly coevolved associations were results of convergent evolution. Given the natural abundance of bacteria, nematodes and insects, it is surprising that only these two associations with no intermediate forms are widely studied in the entomopathogenic context. Discovering analogous systems involving novel bacterial and nematode species would shed light on the evolutionary processes involved in the transition from free living organisms to …

Elucidation Of The Photorhabdus Temperata Genome And Generation Of A Transposon Mutant Library To Identify Motility Mutants Altered In Pathogenesis, Sheldon G. Hurst Iv, Holli Rowedder, Brandye Michaels, Hannah Bullock, Ryan Jackobeck, Feseha Abebe-Akele, Umjia Durakovic, Jon Gately, Erik Janicki, Louis S. Tisa

New Hampshire Agricultural Experiment Station Publications

The entomopathogenic nematode Heterorhabditis bacteriophora forms a specific mutualistic association with its bacterial partner Photorhabdus temperata. The microbial symbiont is required for nematode growth and development, and symbiont recognition is strain specific. The aim of this study was to sequence the genome of P. temperata and identify genes that plays a role in the pathogenesis of the Photorhabdus-Heterorhabditis symbiosis. A draft genome sequence of P. temperata strain NC19 was generated. The 5.2-Mb genome was organized into 17 scaffolds and contained 4,808 coding sequences (CDS). A genetic approach was also pursued to identify mutants with altered motility. A bank of 10,000 …

Modeling Impacts Of Changes In Temperature And Water Table On C Gas Fluxes In An Alaskan Peatland, Jia Deng, Changsheng Li, Steve Frolking

Earth Sciences

Northern peatlands have accumulated a large amount of organic carbon (C) in their thick peat profile. Climate change and associated variations in soil environments are expected to have significant impacts on the C balance of these ecosystems, but the magnitude is still highly uncertain. Verifying and understanding the influences of changes in environmental factors on C gas fluxes in biogeochemical models are essential for forecasting feedbacks between C gas fluxes and climate change. In this study, we applied a biogeochemical model, DeNitrification-DeComposition (DNDC), to assess impacts of air temperature (T_A) and water table (WT) on C gas fluxes …

Relationship Of Phenotypic Variation And Genetic Admixture In The Saltmarsh–Nelson's Sparrow Hybrid Zone, Jennifer Walsh, W. Gregory Shriver, Brian J. Olsen, Kathleen M. O'Brien, Adrienne I. Kovach

New Hampshire Agricultural Experiment Station Publications

Hybridization is influential in shaping species' dynamics and has many evolutionary and conservation implications. Identification of hybrid individuals typically relies on morphological data, but the assumption that hybrids express intermediate traits is not always valid, because of complex patterns of introgression and selection. We characterized phenotypic and genotypic variation across a hybrid zone between 2 tidal-marsh birds, the Saltmarsh Sparrow (Ammodramus caudacutus) and Nelson's Sparrow (A. nelsoni) (n = 290), and we sought to identify morphological traits that could be used to classify admixed individuals. Sparrows were sampled from a total of 34 marshes, including 23 sympatric and 11 putatively …

Extension Stakeholder Engagement: Adapting To The Twenty-First Century, Charles A. French

Natural Resources & the Environment

Over the past 100 years, a number of societal trends have influenced how Cooperative Extension engages public audiences in its outreach and education efforts. These trends include rapid evolution in communication technology, greater specialization of Land-Grant University faculty, and diversification of funding sources. In response, Extension organizations have adapted their engagement approach, incorporated new technologies, modified their organizational structures, and even expanded the notion of public stakeholders to include funders, program nonparticipants, and others. This article explores the implications for future Extension efforts using two case studies—one which explores how a community visioning program incorporated new ways of engaging local …

The Personality Systems Framework: Current Theory And Development, John D. Mayer

Psychology

The personality systems framework is a fieldwide outline for organizing the contemporary science of personality. I examine the theoretical impact of systems thinking on the discipline and, drawing on ideas from general systems theory, argue that personality psychologists understand individuals’ personalities by studying four topics: (a) personality’s definition, (b) personality’s parts (e.g., traits, schemas, etc.), (c) its organization and (d) development. This framework draws on theories from the field to create a global view of personality including its position and major areas of function. The global view gives rise to new theories such as personal intelligence—the idea that people guide …

Understorey Plant Community And Light Availability In Conifer Plantations And Natural Hardwood Forests In Taiwan, Tzu-Yang Liu, Kuo-Chuan Lin, Matthew A. Vadeboncoeur, Ming-Zhen Chen, Meng-Yuan Huang, Teng-Chiu Lin

Faculty Publications

Questions: What are the effects of replacing mixed species natural forests with Cryptomeria japonica plantations on understorey plant functional and species diversity? What is the role of the understorey light environment in determining understorey diversity and community in the two types of forest?

Location: Subtropical northeast Taiwan.

Methods: We examined light environments using hemispherical photography, and diversity and composition of understorey plants of a 35‐yr C. japonica plantation and an adjacent natural hardwood forest.

Results: Understorey plant species richness was similar in the two forests, but the communities were different; only 18 of the 91 recorded understorey plant species occurred …

Crop Rotational Diversity Enhances Belowground Communities And Functions In An Agroecosystem, L. K. Tiemann, A. Stuart Grandy, E. E. Atkinson, E. Marin-Spiotta, M. D. Mcdaniel

Faculty Publications

Biodiversity loss, an important consequence of agricultural intensification, can lead to reductions in agroecosystem functions and services. Increasing crop diversity through rotation may alleviate these negative consequences by restoring positive aboveground–belowground interactions. Positive impacts of aboveground biodiversity on belowground communities and processes have primarily been observed in natural systems. Here, we test for the effects of increased diversity in an agroecosystem, where plant diversity is increased over time through crop rotation. As crop diversity increased from one to five species, distinct soil microbial communities were related to increases in soil aggregation, organic carbon, total nitrogen, microbial activity and decreases in …
