title: Litterfall in Hemlock Removal Experiment at Harvard Forest since 2005

description: Hemlock decline in New England is caused by direct and indirect effects of invasion of the hemlock woolly adelgid. Direct damage from the insect is causing gradual mortality of hemlock, and widespread harvesting of hemlock in advance of mortality, in contrast, causes immediate mortality and removal of biomass from the site. Although both processes affect thousands of acres of forest annually we have only a limited understanding of their effects on forest ecosystem function and productivity and the nature of the subsequent forest community. We anticipate that harvesting will yield different consequences than gradual mortality from the insect. Therefore we designed an experiment to simulate these contrasting impacts, by logging or girdling hemlock stands. Results from the experimental treatments will be compared to the changes observed in forests that are being infested by the adelgid, and can also be included in integrated analyses of a suite of large experiments that form a core component of the Harvard Forest LTER program.

title: Plantation Biodiversity Plots at Harvard Forest since 2007

description: Plantations have been part of forestry at Harvard Forest since its beginning. Plantations were established from 1911-1944, usually on open or cut-over land. The objectives for plantation forests at Harvard Forest were to: increase amount of productive forest land; examine the suitability of various species and cultivars to New England conditions; and test planting and tending methods. At first, mainly small plantings (less than 1 to 4 acres) were established primarily on "blank" lands. Some larger plantations (20+ acres) were established on cut-over land around 1930.
 The bulk of the plantings were red pine, white pine and spruce (white and Norway), but several other conifers were also planted. The maximum amount of land in plantations came to about 270 acres (less than 10% of Harvard Forest’s land base). Tending of the plantations, especially weeding in the decade following establishment, but also in-filling, pruning and thinning, was conducted and carefully documented. However, tending of plantations ceased about 1950.
 Since then, the fate of the plantations has been mixed. Some plantations were out-competed by native forest with only scattered planted trees remaining. A few acres of plantations were harvested in the 1950s. About 40 acres of plantations were harvested in the 1990s. As of 2007, approximately 135 acres remained. These stands range in age from 60-90 years old. Some stands have substantial areas blown down. We developed a management plan to harvest about 80 acres of mature plantation forests beginning in 2008 in order to terminate these long term experiments, to regenerate a diversity of native tree species and restore native forests to these sites, and to initiate a new suite of long term experiments. For the next 10-15 years, the harvested areas will provide early successional habitat for a variety of wildlife species.
 A suite of permanent vegetation plots was established throughout the plantations to assess vegetation structure in plantations and predict future dynamics in harvested and early seral habitats. An initial objective of the baseline survey was to characterize current tree regeneration and understory flora that will in large part determine the future composition of these forests as the overstory is harvested or senesces.

title: Arctic maritime incident records with weather observations (2005-2017)

description: A new database has been created for the risk analysis of Arctic maritime incidents by combining data from two sources. The first dataset contains records of incidents occurring between 2005 and 2017, featuring information on date, location, vessel type, incident type, and vessel length. The second dataset includes weather variables extracted for the same period, filtered to match the location and date of the incidents. These datasets have been integrated to form a comprehensive database that combines incident details, vessel characteristics, and environmental conditions.

title: Short-Term Effects on Vegetation in Soil Warming Plus Nitrogen Addition Experiment at Harvard Forest 2006

description: The purpose of this experiment is to examine the interactive affects of warming and N additions on plant diversity. The experiment consists of four treatments (control, heated +N, heated -N, +N only) with six replicates per treatment in a completely randomized design. Average soil temperature in the heated plots will be elevated 5 deg C above ambient by the use of buried heating cables placed at 10 cm depth in the soil and spaced 20 cm apart. The heating cables will be controlled by a data logger that monitors thermistors (5 per plot) every 10 min. Plots will automatically turn on and off to maintain a 5 deg C temperature difference between the heated and control plots. The N addition plots (heated +N, +N only) will be fertilized following the protocol of the Chronic Nitrogen Addition Study. An aqueous solution of NH4NO3 will be applied at a rate equivalent to the low N plots at the chronic N study (5 g m-2 yr-1). Fertilizer will be applied in equal monthly doses during the growing season (Apr-Oct). The control plots and unfertilized, heated plots (heated -N) will receive water only.

title: Umbilicaria Mammulata and Nitrogen Deposition at Harvard Forest 2006

description: Atmospheric N has quadrupled due to anthropogenic inputs and is projected to double again by 2050. The lichen Umbilicaria mammulata relies primarily on atmospheric deposition for nutrients, including N. Much of this species’ geographic distribution coincides with the N deposition gradient in the eastern US. We were interested in the potential impacts of N deposition on this species under realistic field conditions. Lichens were collected at six sites, ranging from Maine (low deposition) to West Virginia (high deposition). Thalli were analyzed for %C, %N, C:N, specific thallus weight (a measure of thickness), chlorophyll content, and chlorophyll fluorescence. Using stepwise regression we identified the most predictive model(s) using N deposition, environmental variables, and climate to predict differences in lichen ecophysiology and biochemistry across the gradient. While N deposition was important in predicting some responses, the model that best predicted %N in lichen only included mean minimum temperature, mean annual precipitation, and substrate slope. In controlled experiments at Grandfather Mountain (Linville NC) lichens were fertilized in situ with N to mimic deposition projected for 2050. There were no significant differences between control and fertilized thalli for any response variables, but differences did exist among sites. The results of this study highlight the complexities associated with sampling along a gradient of one factor in a multivariate environment.

title: 20-Year Root Mass in Chronic Nitrogen Amendment Experiment at Harvard Forest 2008

description: Forests typically respond to nitrogen additions with increased productivity, hence a long-held paradigm was that chronic additions of anthropogenically-derived atmospheric deposition would have positive ecosystem effects. However, twenty years of work at the Harvard Forest Chronic N Deposition plots, and in other forest ecosystems as well, has shown that that this simplistic view is incomplete. For example, enhanced ammonium uptake increases soil acidity, leading to mobilization of aluminum, and loss of nutrient cations (e.g. Mg2+, Ca2+, and K+ ) all of which influence root mass, turnover, and activity. 
 To address long-term impacts of N additions on forest root mass, we removed O-horizon (forest floor) samples from the Chronic N hardwood and red pine stands to quantify the total mass of roots.
 We found that long term N additions had contrasting results in the two forests. In the hardwood plots, total root mass (less than 2mm) increased from 0.167 + 0.026 (S.E.) kg m-2 in the control plot to 0.434 + 0.170 kg m-2 in the high N plots. In contrast, in the red pine stand, roots declined from 0.074 + 0.011 (S.E.) kg m-2 in the control plot to 0.031 + 0.016 kg m-2 in the high N plots. These data are in agreement with data for aboveground productivity at the Chronic N plots, which show stimulated growth in the hardwoods and severe growth declines and enhanced mortality in the pine stand.

An explanatory design with latent variables and the statistical software SAS 9.4 were used for the validation and adaptation to Spanish and analysis of the data of the items, dimensions, fit of the model in the Virtuous Leadership Questionnaire in work psychologists and organizations and people who exercise leadership functions in Chile. The levels of agreement between judges for the adaptation to the Spanish language, the confirmatory factorial analysis of first order with four dimensions shows statistical indices of inefficient for the absolute, comparative and parsimonious adjustments. However, second-order confirmatory factor analysis with two dimensions shows an efficient fit for the item, model, and parameter matrices.

title: Autumnal Litter Input in DIRT Litter Manipulation Experiment at Harvard Forest 2008

description: Climate change will alter forest ecosystem productivity, changing the quantity and quality of detrital inputs to soil and altering rates of soil organic matter (SOM) accumulation and stabilization. To examine changes in forest soil SOM pools, we have used the Detritus Input and Removal Treatments (DIRT) Project to alter organic matter input rates and sources (roots, leaves) to soils, allowing us to measure contributions of organic matter sources to long-term SOM storage at five temperate forests (Harvard Forest, HJ Andrews, Bousson (PA) Experimental Forest (BEF), U. Michigan Biological Station (UMBS), Síkfokut ILTER, Hungary). Organic matter inputs are altered by excluding or adding leaf inputs, or by excluding roots from forested plots. Soil respiration partitioning at HF, BEF, and UMBS shows that soil fertility controls the allocation of C to above- and belowground tissue. At UMBS, glacial outwash sandy soils are extremely low in N, and C released from root respiration plus root litter decomposition is 87% of total soil respiration. Conversely, at the N-rich BEF site, total belowground sources of CO2 are only 61% of soil respiration, with 47% attributed to root litter. These data suggest that at BEF, leaf litter, comprising only 39% of soil respiration, would be a more important source of long-term SOM than root litter. However, soil chemistry and radiocarbon data have shown us that long-term soil C storage is complex.
 The year 2010 represents the 20-year anniversary of the initiation of DIRT treatments at the Harvard Forest (2010), and we are therefore planning to conduct systematic sampling campaigns for a comprehensive study of changes in SOM quality after long-term manipulation of inputs. One objective is to quantify how 20 years of litter input alterations have affected SOM quantity and quality at the surface (0-20 cm) and deeper in the soil profile (20-100 cm). To uderstand these changes, we need to quantify the quantity and quality of aboveground litter inputs.
 Total aboveground litter inputs were 300.4 + 8.9 (SE, n=21) g m-2. In congruence with the data for aboveground biomass, black oak contributed the dominant mass (73.9%) of litter inputs; red maple and paper birch together contributed 23.26% of the total. Six other tree species collectively constituted the balance of litter inputs.
