Plant Community Structure Mediates Potential Methane Production And Potential Iron Reduction In Wetland Mesocosms., Sarah E. Andrews, R Schultz, Serita D. Frey, V Bouchard, R Varner, Mark J. Ducey

Natural Resources & the Environment

Abstract

Wetlands are the largest natural source of methane to the atmosphere, but factors controlling methane emissions from wetlands are a major source of uncertainty in greenhouse gas budgets and projections of future climate change. We conducted a controlled outdoor mesocosm experiment to assess the effects of plant community structure (functional group richness and composition) on potential methane production and potential iron reduction in freshwater emergent marshes. Four plant functional groups (facultative annuals, obligate annuals, reeds, and tussocks) were arranged in a full-factorial design and additional mesocosms were assigned as no-plant controls. Soil samples from the top 10 cm were …

Trends In Stream Nitrogen Concentrations For Forested Reference Catchments Across The Usa, A. Argerich, S. L. Johnson, S. D. Sebestyen, C. C. Rhoades, E. Greathouse, J. D. Knoepp, M. B. Adams, G. E. Likens, J. L. Campbell, William H. Mcdowell, F. N. Scatena, G. G. Ice

New Hampshire EPSCoR

To examine whether stream nitrogen concentrations in forested reference catchments have changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr of data collected from 22 catchments at seven USDA Forest Service Experimental Forests. Trends in stream nitrogen presented high spatial variability both among catchments at a site and among sites across the USA. We found both increasing and decreasing trends in monthly flow-weighted stream nitrate and ammonium concentrations. At a subset of the catchments, we found that the length and period of analysis influenced whether trends were positive, negative or non-significant. Trends …

Experimental And Natural Warming Elevates Mercury Concentrations In Estuarine Fish, Jennifer A. Dijkstra, Kate L. Buckman, Darren Ward, David W. Evans, Michele Dionne, Celia Chen

Center for Coastal and Ocean Mapping

Marine food webs are the most important link between the global contaminant, methylmercury (MeHg), and human exposure through consumption of seafood. Warming temperatures may increase human exposure to MeHg, a potent neurotoxin, by increasing MeHg production as well as bioaccumulation and trophic transfer through marine food webs. Studies of the effects of temperature on MeHg bioaccumulation are rare and no study has specifically related temperature to MeHg fate by linking laboratory experiments with natural field manipulations in coastal ecosystems. We performed laboratory and field experiments on MeHg accumulation under varying temperature regimes using the killifish, Fundulus heteroclitus. Temperature treatments were …

Comparison Of Forest Attributes Derived From Two Terrestrial Lidar Systems., Mark J. Ducey, Rasmus Astrup, Stefan Seifart, Hans Pretzsch, Bruce C. Larson, K David Coates

Natural Resources & the Environment

Terrestrial lidar (TLS) is an emerging technology for deriving forest attributes, including conventional inventory and canopy characterizations. However, little is known about the influence of scanner specifications on derived forest parameters. We compared two TLS systems at two sites in British Columbia. Common scanning benchmarks and identical algorithms were used to obtain estimates of tree diameter, position, and canopy characteristics. Visualization of range images and point clouds showed clear differences, even though both scanners were relatively high-resolution instruments. These translated into quantifiable differences in impulse penetration, characterization of stems and crowns far from the scan location, and gap fraction. Differences …

Sobol' Sensitivity Analysis Of The Holocene Peat Model: What Drives Carbon Accumulation In Peatlands?, Anne Quillet, Michelle Garneau, Steve Frolking

Earth Sciences

Understanding the development of northern peatlands and their carbon accumulation dynamics is crucial in order to confidently integrate northern peatlands into global carbon cycle models. To achieve this, northern peatland models are becoming increasingly complex and now include feedback processes between peat depth, decomposition, hydrology, and vegetation composition and productivity. Here we present results from a global sensitivity analysis performed to assess the behavior and parameter interaction of a peatland simulation model. A series of simulations of the Holocene Peat Model were performed with different parameter combinations in order to assess the role of parameter interactions on the simulated total …

Evidence For Elevated Emissions From High-Latitude Wetlands Contributing To High Atmospheric Ch4 Concentration In The Early Holocene, Zicheng Yu, Julie Loisel, Merritt R. Turetsky, Shanshan Cai, Yan Zhao, Steve Frolking, Glenn M. Macdonald, Jill L. Bubier

Earth Sciences

The major increase in atmospheric methane (CH₄) concentration during the last glacial-interglacial transition provides a useful example for understanding the interactions and feedbacks among Earth's climate, biosphere carbon cycling, and atmospheric chemistry. However, the causes of CH₄ doubling during the last deglaciation are still uncertain and debated. Although the ice-core data consistently suggest a dominant contribution from northern high-latitude wetlands in the early Holocene, identifying the actual sources from the ground-based data has been elusive. Here we present data syntheses and a case study from Alaska to demonstrate the importance of northern wetlands in contributing to high …

Testing Of Great Bay Oysters For Two Protozoan Pathogens, New Hampshire Fish And Game Department, Douglas E. Grout

PREP Reports & Publications

Two protozoan pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo), are known to be present in Great Bay oysters. With funds provided by the Piscataqua Region Estuaries Partnership (PREP), the Marine Fisheries Division of the New Hampshire Fish and Game Department (NHF&G) continues to assess the presence and intensity of both of these disease conditions in oysters from the major beds within the Great Bay estuarine system. Histological examinations of Great Bay oysters have also revealed other endoparasites.

The Crater Special Issue Of Space Weather: Building The Observational Foundation To Deduce Biological Effects Of Space Radiation, Nathan A. Schwadron, Sonya S. Smith, Harlan E. Spence

Physics & Astronomy

[1] The United States is preparing for exploration beyond low-Earth Orbit (LEO). However, the space radiation environment poses significant risks. The radiation hazard is potentially severe but not sufficiently well characterized to determine if long missions outside LEO can be accomplished with acceptable risk [Cucinotta et al., 2001; Schwadron et al., 2010; Cucinotta et al., 2010]. Radiation hazards may be over- or under-stated through incomplete characterization in terms of net quantities such as accumulated dose. Time-dependent characterization often changes acute risk estimates [NCRP, 1989; Cucinotta, 1999; Cucinotta et al., 2000; George et al., 2002]. For example, events with high accumulated …

Climate Change At The Ecosystem Scale: A 50-Year Record In New Hampshire, Steven P. Hamburg, Matthew A. Vadeboncoeur, Andrew D. Richardson, Amey S. Bailey

All Materials

Observing the full range of climate change impacts at the local scale is difficult. Predicted rates of change are often small relative to interannual variability, and few locations have sufficiently comprehensive long-term records of environmental variables to enable researchers to observe the fine-scale patterns that may be important to understanding the influence of climate change on biological systems at the taxon, community, and ecosystem levels. We examined a 50-year meteorological and hydrological record from the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, an intensively monitored Long-Term Ecological Research site. Of the examined climate metrics, trends in temperature were the …
