title: Population Dynamics of Pink Lady Slipper in Weston MA since 2014

description: The pink lady slipper (Cypripedium acaule) is an iconic understory plant of Massachusetts forests. It is easy to find and identify and is on the United States Forest Service list of white-tailed deer browse. Brian Donahue and members of the Weston Conservation Commission engaged a local garden club to start surveying trails for pink lady slippers. The project was designed to engage the community in a citizen science project that would bring community members into the discussion of conservation land management decisions. It also supports the long-term goal of linking white-tailed deer browse to lady slipper community dynamics.

title: Supplemental material for Cotterill et al. 2020: Parsing the effects of demography, climate, and management on recurrent brucellosis outbreaks in elk. Journal of Applied Ecology.

description: Zoonotic pathogens can harm human health and wellbeing directly or by impacting livestock. Pathogens that spillover from wildlife can also impair conservation efforts if humans perceive wildlife as pests. Brucellosis, caused by the bacterium Brucella abortus, circulates in elk and bison herds of the Greater Yellowstone Ecosystem and poses a risk to cattle and humans. Our goal was to understand the relative effects of climatic drivers, host demography, and management control programs on disease dynamics.

Synthesis and applications: Positive serostatus is often weakly correlated with infectiousness but is nevertheless used to make management decisions including lethal removal in wildlife disease systems. We show how this can have adverse consequences whereas efforts that maintain herd immunity can have longer-term protective effects. Climatic drivers may not result in synchronous disease dynamics across populations unless vital rates are also similar because demographic factors have a large influence on disease patterns.

title: Impacts of Hemlock Woolly Adelgid After Preventative Treatment in Lincoln MA 2015-2018

description: In 2007 the town of Lincoln, MA treated the hemlock stand at the Codman estate with root injections of imidacloprid to suppress the invasive insect Hemlock Wooly Adelgid (HWA). This hemlock grove is unique for this area of Massachusetts and dominated by eastern hemlock of approximately 2 feet in diameter with many trees reaching heights of over 120 feet. The treatment goal was to conserve the trees and the stand’s cathedral-like characteristics. To accomplish this goal, every big canopy tree was treated.

title: R Code and Images for Developing a Spatial Concordance Coefficient at Harvard Forest 2010

description: Concordance correlation coefficients have been developed in a variety of different contexts. This problem has been widely addressed in a non-spatial context, but here we consider a coefficient that for a fixed spatial lag allows the comparison of two spatial sequences (e.g., images). We define a spatial concordance coefficient for second-order stationary processes.

title: Development of a Low-Cost, Open Source Miniature Rotary Cell Culture System to Simulate Microgravity within an Irradiated Environment

description: A major challenge for astronauts in long-duration space travel is combatting the hazardous spaceflight environment caused by microgravity and increased levels of ionizing radiation. Microgravity damages cellular DNA by increasing the production of harmful reactive oxygen species, while ionizing radiation damages DNA by creating double-stranded DNA (dsDNA) breaks. Cellular damage due to microgravity and radiation has been investigated using ground-based models, but most models consider microgravity and ionizing radiation alone, or asynchronously. Synchronous modeling better mimics spaceflight conditions and can be used to understand the combined effects of microgravity and ionizing radiation. However, commercially available devices to model microgravity and radiation are rare and costly, requiring both a rotary cell culture system and beam time at a national lab or an independent radiation source. While independent radiation sources are becoming less difficult to use or purchase, commercially available devices to simulate microgravity are still cost prohibitive to many researchers.

In this study, we developed a low-cost, open source cell culture system for studying the role that synchronous ionizing radiation and microgravity play in pathophysiology during spaceflight conditions. Our system was validated by exposing C2C12 mouse myoblast cells to ionizing radiation at levels approximating 9-month and 10-year Mars missions while simulating microgravity. DNA damage to cells was quantified using -H2AX (a fluorescent marker for double-stranded breaks), while reactive oxygen species production was visualized using CellROX green. Cells exposed to long-term mission doses had statistically significant increases in DNA damage and ROS production compared to both the short-term and control conditions. Our proof of concept shows that the low-cost, open source mini-RCCS can be used to mimic the radiation and microgravity hazards of the spaceflight environment at the same level as expensive commercial systems.

title: Northern Range Limit of Aphaenogaster picea in Maine 2015

description: Low temperatures at poleward range margins of terrestrial species tend to match cold tolerance limits, suggesting that range boundaries may be set by evolutionary constraints on cold physiology. The northeastern woodland ant, Aphaenogaster picea, occurs up to approximately 45 °N in central Maine. We combined presence-absence surveys with regression-tree analysis to characterize its northern range limit, and assayed two measures of cold tolerance operating on different time-scales to determine whether and how marginal populations adapt to environmental extremes. The boundary was predicted primarily by temperature, but low winter temperatures did not emerge as the primary correlate of species occurrence. Low summer temperatures and high seasonal variability predicted absence above the boundary, whereas high mean annual temperature (MAT) predicted presence in southern Maine. Locations between these zones formed an east-west band where presence was conditional on precipitation. In contrast, assays of cold tolerance across multiple sites indicated substantial local adaptation of cold tolerance at the range edge, with a 4-minute reduction in chill-coma recovery time across a 2-degree reduction in MAT. Baseline tolerance and capacity for additional plastic cold-hardening shifted in opposite directions, with hardening capacity approaching zero at the coldest sites. This trade-off suggests that populations at range edges may adapt to colder temperatures through genetic assimilation of plastic responses, potentially constraining further adaptation and range expansion.

title: Dataset for "Attributes of Phragmites australis in response to climate change using a common garden study"

description: The response of plant species to environmental change, including climate, is based on phenotypic plasticity. Empirical research can help in understanding how invasive plants adapt to changing conditions for successful establishment. Our goal was to assess the effect of environment of origin and ecotypic variation on phenotypic response of native and invasive Phragmites australis using morphological and ecophysiological measurements. We established a common garden study using seeds collected from Southwest, Midwest, and Great Lakes regions that crossed longitudinal and latitudinal gradients of the US. Within and end of growing season measurements were made for morphological (e.g., height, leaf size, inflorescence) and ecophysiological (e.g., photosynthesis, stomatal conductance, water use efficiency) attributes of all P. australis lineages. Native and invasive lineages differed significantly across regions in the categories of maximum height and stem diameter along with the probability of inflorescence. However, lineages were fairly similar across regions with regard to photosynthesis, stomatal conductance, transpiration and water use efficiency throughout the growing season. The general insignificance in ecophysiology among the lineages and across regions demonstrates adaption or phenotypic plasticity of P. australis. However, morphological characteristics of P. australis may not be as evolutionarily advanced in response to changing conditions, especially drought.

title: Coqui Frog Predator Avoidance and Recognition

description: The purpose of this study was to determine whether coqui frogs from their non-native range responded to native predators the same way as frogs from their native range. Frogs were collected from two sites in Puerto Rico (El Yunque and Rio Abajo) in May 2006 and one site in Hawaii (Hilo) in June 2006. At each site, frogs were collected from a high (> 700 m) and low (< 300 m) elevation population. Of the total number of frogs collected, 100 males were randomly selected to be used in this study (45 and 55 from Hawaii and Puerto Rico, respectively). Three tailless whipscorpions (Phrynus longipes) and three tarantulas (Avicularia laeta) were also collected in Puerto Rico in field sites where frogs were collected and shipped back to a laboratory.

title: Carbon Budget at the Harvard Forest 1992-2015

description: How, where, and why carbon (C) moves into and out of an ecosystem through time are long-standing questions in biogeochemistry. Here, we bring together hundreds of thousands of C-cycle observations at the Harvard Forest in central Massachusetts, USA, a mid-latitude landscape dominated by 80–120-year-old closed-canopy forests. These data answered four questions: (i) where and how much C is presently stored in dominant forest types; (ii) what are current rates of C accrual or loss; (iii) what biotic and abiotic factors contribute to variability in these rates; and (iv) is climate change affecting the forest’s C cycle? Harvard Forest is an active C sink resulting from forest regrowth following land abandonment. Soil and tree biomass comprise nearly equal portions of existing C stocks. Net primary production (NPP) averaged 750–970 g C m-2 yr-1; belowground NPP contributed 30–60% of the total. Mineral soil C measured in the same inventory plots in 1992 and 2013 were too heterogeneous to detect change in soil-C pools; however, radiocarbon data suggest a small but persistent sink of 10–30 g C m-2 yr-1. Net ecosystem production (NEP) in hardwood stands averaged ~300 g C m-2 yr-1. NEP in hemlock-dominated forests averaged ~450 g C m-2 yr-1 prior to infestation by the hemlock woolly adelgid (HWA) in 2013, and then became a net C source. Stand dynamics and climate change in the last three decades enhanced the C sink in hardwood stands; NPP increased 26% between 2000–2014 (p = 0.02) and NEP increased 93% between 1992–2015 (p = 0.13). Compared to long-term global change experiments at the Harvard Forest, the C sink in regrowing biomass equaled or exceeded C cycle modifications imposed by soil warming, N saturation, and hemlock removal. Median forest biomass in the surrounding ecoregion was only 78% of that at the Harvard Forest due to higher timber harvesting rates across the region. Results of this synthesis and comparison to simulation models suggest that forests across the region are likely to accrue C for decades to come but may be disrupted if the frequency or severity of disturbance increases.

title: Glucocorticoids, Energy Metabolites, and Immunity Vary Across Allostatic States for Plateau Side-Blotched Lizards (Uta stansburiana uniformis) Residing in a Heterogeneous Thermal Environment

description: Reptiles rely on thermal heat exchange to achieve body temperatures (Tbody) conducive to maintaining homeostasis. Diurnal changes in the thermal environment are therefore liable to influence allostatic mediation of survival processes (e.g., immunity) during environmental challenges or stressors. However, the extent to which Tbody prompts individual variation in physiology remains largely unexplored in reptiles. Our study tested how circulating energy-mobilizing hormone, energy metabolites, and immunity can vary across basal and stress-induced allostatic states for plateau side-blotched lizards (Uta stansburiana uniformis) residing in a heterogeneous thermal environment. We collected baseline and acute stress blood samples from male lizards to compare changes in plasma corticosterone (CORT), glucose, and bacterial killing ability (BKA) in relation to each other and Tbody. We hypothesized each physiological parameter differs between allostatic states, whereby stress-induced activity increases from baseline. At basal and stress-induced states, we also hypothesized circulating CORT, glucose, and BKA directly correspond with each other and Tbody. We found both CORT and BKA increased while glucose instead decreased from acute stress. At basal and stress-induced allostatic states, we found CORT to be directly related to Tbody while BKA was inversely related to CORT. We also found BKA and glucose were directly related at baseline, but inversely related following acute stress. Overall, these results demonstrate allostatic outcomes from acute stress in a free-living reptile and the role of temperature in mediating energetic state and immunity. Future research on reptilian allostasis should consider multiple environmental conditions and their implications for physiological performance and survival.

title: Determining How Increasing Precipitation Intensity Will Impact Rangelands in Utah.

description: As the atmosphere warms, precipitation events become larger, but less frequent. Yet, there is fundamental disagreement about how increased precipitation intensity will affect vegetation. Walter’s two-layer hypothesis and experiments testing it have demonstrated that precipitation intensity can increase woody plant growth. Observational studies have found the opposite pattern. Not only are the patterns contradictory, but inference is largely limited to grasslands and savannas. We tested the effects of increased precipitation intensity in a shrub-steppe ecosystem that receives >30% of its precipitation as snow. We used 11 (8 m x 8 m) shelters to collect and redeposit rain and snow as larger, more intense events. Total annual precipitation was the same in all plots, but each plot received different precipitation event sizes ranging from 1 mm to 18 mm. Over three growing seasons, larger precipitation event sizes increased soil water availability, sagebrush (Artemisia tridentata) stem radius, and canopy greenness, decreased new root growth in shallow soils, and had no effect on herbaceous plant cover. Thus, we found that increased precipitation intensity can increase soil water availability and woody plant growth in a cold semi-arid system. Assuming that stem growth is positively correlated with shrub reproduction, establishment and spread, results suggest that woody plant encroachment observed around the world in the past 50 years may be explained in part by increasing precipitation intensity. Further, continued atmospheric warming that is likely to increase precipitation intensity may also potentially increase shrub encroachment in the future

title: LANDIS-II PnET Impacts of Warming on Forest Net Primary Productivity in New England 2010-2100

description: Climate warming is expected to lengthen growing seasons of temperate forest ecosystems and increase gross primary productivity. Simultaneously, warming is expected to increase summer ecosystem respiration, which could offset gains accrued from longer growing seasons. These responses have been observed during anomalously warm years, but the role of future climate change on phenological trade‐offs and how they affect net primary productivity (NPP) at regional scales in temperate forests remain unexplored. We simulated scenarios of climate change on monthly forest NPP throughout 18 million hectares of temperate forests in New England, USA, through year 2100. Using an ecophysiological model coupled to a forest landscape model, we simulated scenarios of climate change on monthly NPP. A high emission scenario (RCP 8.5), resulted in longer growing seasons that offset midsummer ecosystem respiration costs and produced greater annual NPP throughout the study landscape compared to simulations using the current climate. In spring and autumn months, temperature was positively associated with greater NPP; in summer months, the relationship was negative. Spatially, the greatest increase in NPP occurred in the warmer southern region under a warm climate scenario with increased precipitation. Under a warm scenario with drier conditions, the greatest increase in NPP occurred in the cooler northern region. Phenological trade‐offs will affect NPP of future forests and their potential to serve as a negative feedback to climate change. Barring other limitations, longer growing seasons will offset greater respiratory demands and contribute to increases in NPP throughout the temperate forests of New England in the future.

title: Data for: Vestibular attenuation to random-waveform galvanic vestibular stimulation during standing and treadmill walking

description: The ability to move and maintain posture in space is critically dependent on motion and orientation information provided by the vestibular system. When this system delivers noisy or erred information it can, in some cases, be disregarded through habituation. Here we investigate whether multiple mechanisms of habituation act to attenuate vestibulomotor gain due to noise added using random-waveform electric vestibular stimulation (EVS). Forty-five participants completed one of three conditions. Each condition consisted of two four-minute standing periods with stimulation surrounding a one-hour period of either walking with stimulation, walking without stimulation, or sitting quietly. Participants stood and walked on an instrumented treadmill to record horizontal forces at the feet. We quantified habituation by comparing vestibular stimulus-horizontal force gain between conditions. First stimulus exposure caused an 18% decrease in gain during the first forty seconds of standing. Habituation recommenced only when subjects walked with stimulation; resulting in a 38% decrease in gain over sixty-minutes that did not transfer to standing following walking. The disparity in habituation dynamics and absent carry over between standing and walking suggests that at least two habituative mechanisms, one associated with first exposure to the stimulus and another that is task specific, act to attenuate vestibulomotor gain.
