Experiential Student Learning and Collaborative Research: Understanding Tropical Ecosystem Response to Climate Change from Leaves to Landscapes.

During January 2012, I traveled to Costa Rica to visit potential field sites for a future UNH J-term course in Tropical Ecology and to collect preliminary data for a new research project linked to the course. Both of these initiatives are in collaboration with Dr. Michael Palace, a research scientist at UNH’s Earth Systems Research Center. Together, we visited three sites in Costa Rica, each having very different climates and vegetation: Curu Wildlife Refuge, a tropical dry deciduous forest receiving only about 1,500mm …

Demographic Change In The Northern Forest, Kenneth M. Johnson, Susan I. Stewart, Miranda H. Mockrin

Carsey Publications

This brief examines the population redistribution in the Northern Forest, which includes thirty-four counties scattered across northern and central Maine, New Hampshire, New York, and Vermont. Authors Ken Johnson, Susan Stewart, and Miranda Mockrin report that the population of the Northern Forest grew modestly between 2000 and 2010, and the population gains were greatest in recreational areas and least in manufacturing areas. Racial and ethnic diversity is also growing in the Northern Forest, and the population is getting older due to aging in place among current residents and net outmigration among younger populations.

Spatiotemporal Studies Of Black Spruce Forest Soils And Implications For The Fate Of C, Jennifer Harden, Kristen L. Manies, Jonathan O'Donnell, Kristofer Johnson, Steve Frolking, Zhaosheng Fan

Earth Sciences

Post-fire storage of carbon (C) in organic-soil horizons was measured in one Canadian and three Alaskan chronosequences in black spruce forests, together spanning stand ages of nearly 200 yrs. We used a simple mass balance model to derive estimates of inputs, losses, and accumulation rates of C on timescales of years to centuries. The model performed well for the surface and total organic soil layers and presented questions for resolving the dynamics of deeper organic soils. C accumulation in all study areas is on the order of 20–40 gC/m²_/yr for stand ages up to ∼200 yrs. Much …

Permanganate Oxidizable Carbon Reflects A Processed Soil Fraction That Is Sensitive To Management, Steven W. Culman, Sieglinde S. Snapp, Mark A. Freeman, Meagan E.

Permanganate oxidizable C (POXC; i.e., active C) is a relatively new method that can quantify labile soil C rapidly and inexpensively. Despite limited reports of positive correlations with particulate organic C (POC), microbial biomass C (MBC), and other soil C fractions, little is known about what soil fractions POXC most closely reflects. We measured POXC across a wide range of soil types, ecosystems, and geographic areas (12 studies, 53 total sites, n = 1379) to: (i) determine the relationship between POXC and POC, MBC and soil organic C (SOC) fractions, and (ii) determine the relative sensitivity of POXC as a …

Soil Bacterial Communities Of A Calcium-Supplemented And A Reference Watershed At The Hubbard Brook Experimental Forest (Hbef), New Hampshire, Usa, Ganapathi Sridevi, Rakesh Minocha, Swathi A. Turlapati, Katherine C. Goldfarb, Eoin L. Brodie, Louis S. Tisa, Subhash C. Minocha

New Hampshire Agricultural Experiment Station Publications

Soil Ca depletion because of acidic deposition-related soil chemistry changes has led to the decline of forest productivity and carbon sequestration in the northeastern USA. In 1999, acidic watershed (WS) 1 at the Hubbard Brook Experimental Forest (HBEF), NH, USA was amended with Ca silicate to restore soil Ca pools. In 2006, soil samples were collected from the Ca-amended (WS1) and reference watershed (WS3) for comparison of bacterial community composition between the two watersheds. The sites were about 125 m apart and were known to have similar stream chemistry and tree populations before Ca amendment. Ca-amended soil had higher Ca …

Patterns And Perceptions Of Climate Change In A Biodiversity Conservation Hotspot, Joel N. Hartter, Mary D. Stampone, Sadie J. Ryan, Karen Kirner, Colin A. Chapman, Abraham Goldman

Geography

Quantifying local people's perceptions to climate change, and their assessments of which changes matter, is fundamental to addressing the dual challenge of land conservation and poverty alleviation in densely populated tropical regions To develop appropriate policies and responses, it will be important not only to anticipate the nature of expected changes, but also how they are perceived, interpreted and adapted to by local residents. The Albertine Rift region in East Africa is one of the world's most threatened biodiversity hotspots due to dense smallholder agriculture, high levels of land and resource pressures, and habitat loss and conversion. Results of three …

Flow Dynamics Of An Accumulation Basin: A Case Study Of Upper Kahiltna Glacier, Mount Mckinley, Alaska, Seth Campbell, K Kreutz, Erich Osterberg, Steven Arcone, Cameron P. Wake, Kevin Volkening, Dominic Winski

Earth Sciences

We interpreted flow dynamics of the Kahiltna Pass Basin accumulation zone on Mount McKinley, Alaska, USA, using 40, 100 and 900 MHz ground-penetrating radar profiles and GPS surface velocity measurements. We found dipping, englacial surface-conformable strata that experienced vertical thickening as the glacier flowed westward from a steep, higher-velocity (60 m a–1) region into flat terrain associated with a 908 bend in the glacier and lower velocities (15 m a–1) to the south. Stratigraphy near the western side of the basin was surface-conformable to 170 m depth and thinned as flow diverged southward, down-glacier. We found complex strata beneath the …

Melt Regimes, Internal Stratigraphy, And Flow Dynamics Of Three Glaciers In The Alaska Range, Seth Campbell, K Kreutz, Erich Osterberg, Steven Arcone, Cameron P. Wake, Douglas Introne, Kevin Volkening, Dominic Winski

Earth Sciences

We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska. We show the wet, percolation and dry snow zones located below 2700 m a.s.l., at 2700 to 3900 m a.s.l. and above 3900 m a.s.l., respectively. We successfully imaged glacier ice depths upwards of 480 m using 40–100 MHz GPR frequencies. This depth is nearly double previous depth measurements reached using mid-frequency GPR systems on temperate glaciers. Few Holocene-length climate records are available in …
