Determining Presence/Absence And Abundance Of Declining Shrubland-Dependent Songbirds In Human-Created Shrublands In Southeastern New Hampshire, Erica Holm, Jenny Leigh Gibson Kerr

Inquiry Journal 2016

Shrubland habitat and wildlife species have been declining throughout most of New England since the 1950s. Many songbirds have been declining at a rate of 4 to 7 percent per year in New England, and these species require large openings to breed. Large shrubland openings are uncommon and today’s birds rely primarily on humans to create and maintain their required habitats. Our study focused on prairie warblers and field sparrows. We determined presence/absence and abundance of these birds in 53 shrubland habitats in Stafford County, New Hampshire, of four types: recent clearcuts, powerline rights-of-way, regenerating old fields and gravel pits. …

Comparison Of Cuticular Hydrocarbons In Three Populations Of The Carpenter Bee “Ceratina Calcarata” To Help Understand Their Role In Social Evolution, Sean Lombard

Inquiry Journal 2016

For the second summer in a row I analysed the composition of cuticular hydrocarbons (CHCs) on carpenter bees Ceratina calcarata, this time in populations from Missouri and Georgia as well as from New Hampshire. My goal was to find out if the CHC compositions differed significantly among these three populations. My results affirmed our prediction that the CHC composition varies by population, though there does appear to be some overlap across populations. The CHC variation observed suggests that chemical composition changes with latitude. CHCs are thought to have initially evolved to prevent water loss and then became part of chemical …

A High-Density Linkage Map Of The Ancestral Diploid Strawberry, Fragaria Iinumae, Constructed With Single Nucleotide Polymorphism Markers From The Istraw90 Array And Genotyping By Sequencing, Lise L. Mahoney, Daniel J. Sargent, Feseha Abebe-Akele, David J. Wood, Judson A. Ward, Nahla V. Bassil, James F. Hancock, Kevin M. Folta, Thomas M. Davis

New Hampshire Agricultural Experiment Station Publications

Fragaria iinumae Makino is recognized as an ancestor of the octoploid strawberry species, which includes the cultivated strawberry, Fragaria ×ananassa Duchesne ex Rozier. Here we report the construction of the first high-density linkage map for F. iinumae. The F. iinumae linkage map (Fii map) is based on two high-throughput techniques of single nucleotide polymorphism (SNP) genotyping: the IStraw90 Array (hereafter “Array”), and genotyping by sequencing (GBS). The F2 generation mapping population was derived by selfing F. iinumae hybrid F1D, the product of a cross between two divergent F. iinumae accessions collected from Hokkaido, Japan. The Fii map consists of seven …

Zonal tillage (e.g. ridge tillage, RT) separates management of row and inter-row positions, while non-zonal tillage (e.g. chisel plough, CP) applies management uniformly across a field. This may have large effects on soil hydrothermal properties, affecting soil processes and crop development. We examined the effects of RT versus CP on soil hydrothermal conditions under maize (Zea mays L.) at four sites spanning the US Corn Belt over two growing seasons (2012–2013). We also investigated whether RT, as a result of changes in hydrothermal conditions, could stimulate greater soil nitrogen (N) availability during peak maize N demand. We captured wide variation …

Monitoring Macroalgae In The Great Bay Estuary For 2014, David M. Burdick, Arthur C. Mathieson, Sydney Nick

PREP Reports & Publications

Four more intertidal fixed transect sites were added to the long5term macroalgal monitoring array, resulting in a total of eight sites for the Great Bay Estuary. Monitoring results from 2014 show high levels of cover of nuisance green and red algae (Ulva and Gracilaria, respectively) at all sites except near the mouth of the Estuary. Seasonal sampling of algal cover confirmed earlier work that showed mid5summer accumulations of green algae (primarily Ulva)lactuca) were largely replaced in late summer and fall by red algae (two species of Graciliaria, one native and the other introduced). A determination of whether intertidal macroalgal populations …

Differential Introgression And The Maintenance Of Species Boundaries In An Advanced Generation Avian Hybrid Zone, Jennifer Walsh, W. Gregory Shriver, Brian J. Olsen, Adrienne I. Kovach

New Hampshire Agricultural Experiment Station Publications

Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others. Differential introgression of molecular or phenotypic markers can thus provide insight into factors contributing to reproductive isolation. We characterized patterns of genetic variation across a hybrid zone between two tidal marsh birds, Saltmarsh (Ammodramus caudacutus) and Nelson’s (A. nelsoni) sparrows (n = 286), and compared patterns of introgression among multiple genetic markers and phenotypic traits.

Results: Geographic and genomic cline analyses revealed variable patterns of introgression among marker types. Most markers exhibited …

Nitrogen (N) supply often limits the productivity of temperate forests and is regulated by a complex mix of biological and climatic drivers. In excess, N is linked to a variety of soil, water, and air pollution issues. Here, we use results from an elevation gradient study and historical data from the long‐term Hubbard Brook Ecosystem Study (New Hampshire, USA) to examine relationships between changes in climate, especially during winter, and N supply to northern hardwood forest ecosystems. Low elevation plots with less snow, more soil freezing, and more freeze/thaw cycles supported lower rates of N mineralization than high elevation plots, …

Human impacts on biogeochemical cycles are evident around the world, from changes to forest structure and function due to atmospheric deposition, to eutrophication of surface waters from agricultural effluent, and increasing concentrations of carbon dioxide (CO2) in the atmosphere. The National Ecological Observatory Network (NEON) will contribute to understanding human effects on biogeochemical cycles from local to continental scales. The broad NEON biogeochemistry measurement design focuses on measuring atmospheric deposition of reactive mineral compounds and CO2 fluxes, ecosystem carbon (C) and nutrient stocks, and surface water chemistry across 20 eco‐climatic domains within the United States for 30 yr. Herein, we …

Anthropogenic Habitats Facilitate Dispersal Of An Early Successional Obligate: Implications For Restoration Of An Endangered Ecosystem, Katrina E. Amaral, Michael W. Palace, Kathleen M. O'Brien, Lindsey E. Fenderson, Adrienne I. Kovach

New Hampshire Agricultural Experiment Station Publications

Landscape modification and habitat fragmentation disrupt the connectivity of natural landscapes, with major consequences for biodiversity. Species that require patchily distributed habitats, such as those that specialize on early successional ecosystems, must disperse through a landscape matrix with unsuitable habitat types. We evaluated landscape effects on dispersal of an early successional obligate, the New England cottontail (Sylvilagus transitionalis). Using a landscape genetics approach, we identified barriers and facilitators of gene flow and connectivity corridors for a population of cottontails in the northeastern United States. We modeled dispersal in relation to landscape structure and composition and tested hypotheses about the influence …

Stoichiometry And Change Of The Mrna Closed-Loop Factors As Translating Ribosomes Transit From Initiation To Elongation, Xin Wang, Wen Xi, Shaun Toomey, Yueh-Chin Chiang, Jiri Hasek, Thomas M. Laue, Clyde L. Denis

New Hampshire Agricultural Experiment Station Publications

Protein synthesis is a highly efficient process and is under exacting control. Yet, the actual abundance of translation factors present in translating complexes and how these abundances change during the transit of a ribosome across an mRNA remains unknown. Using analytical ultracentrifugation with fluorescent detection we have determined the stoichiometry of the closed-loop translation factors for translating ribosomes. A variety of pools of translating polysomes and monosomes were identified, each containing different abundances of the closed-loop factors eIF4E, eIF4G, and PAB1 and that of the translational repressor, SBP1. We establish that closed-loop factors eIF4E/eIF4G dissociated both as ribosomes transited polyadenylated …

De Novo Genome Assembly Of Geosmithia Morbida, The Causal Agent Of Thousand Cankers Disease, Taruna A. Schuelke, Anthony Westbrook, Kirk Broders, Keith Woeste, Matthew D. Macmanes

New Hampshire Agricultural Experiment Station Publications

Geosmithia morbida is a filamentous ascomycete that causes thousand cankers disease in the eastern black walnut tree. This pathogen is commonly found in the western U.S.; however, recently the disease was also detected in several eastern states where the black walnut lumber industry is concentrated. G. morbida is one of two known phytopathogens within the genus Geosmithia, and it is vectored into the host tree via the walnut twig beetle. We present the first de novo draft genome of G. morbida. It is 26.5 Mbp in length and contains less than 1% repetitive elements. The genome possesses an estimated 6,273 …

The Educated Citizen And Global Public Health Issues: One Model For Integration Into The Undergraduate Curriculum, Rosemary M. Caron

Health Management & Policy

The Educated Citizen Initiative proposes that an understanding of public-health issues is a core component of an educated citizenry and is essential to develop one’s societal responsibility. This initiative supports the Institute of Medicine’s recommendation that “all undergraduates should have access to education in public health.” Furthermore, the Liberal Education and America’s Promise (LEAP) framework developed by the Association of American Colleges and Universities supports the “integration of public-health education into general and liberal education with an aim to produce an educated citizenry.” The LEAP framework is implemented by teaching about the role of social determinants in a population’s health …
