title: Source-Sink Dynamics of Garlic Mustard Invasion at Harvard Forest 2004-2006

description: We are investigating the role of disturbance history, source-sink metapopulation dynamics, and genetic adaptation to different canopy environments in the invasion success of Alliaria petiolata in the New England understory. In these studies, we employ a combination of population-level experiments, metapopulation studies, and landscape-level historical analyses. We have initiated a statewide survey of forested locations to determine the presence and absence of garlic mustard with respect to major pathways of invasion via past and present habitat disturbances. More explicit spatial analyses will test whether past sites of open canopy could have acted as corridors for the spread of invasive populations to present locations. This broad analysis will enable us to evaluate the generality of emerging conclusions from our population-level studies for predicting the broad-scale factors controlling the distribution, pattern and abundance of non-native species. At the population-level, we have begun long term demographic modeling of A. petiolata and experiments to test for habitat-specific natural selection on physiological, phenological, and allocational traits in sites with different canopy structure (edge or understory). In long term demographic analyses, we will use matrix population models to determine the relative contributions of subpopulations in different habitats to forest invasion. In ongoing reciprocal transplant studies, we will asses whether the maternal source habitat of a propagule contributes to its germination and survival in contrasting habitats.

title: Ennya Chrysura ecdysis

description: This data file reports the observed variables' results during pre-ecdysis, ecdysis proper, and postecdysis of Ennya chrysura (Hemiptera, Membracidae) for 11 individuals, six females (F) and five males (M). Units for all variables are seconds (s) except for contractions or frequencies, in which the unit is either the number of contractions, contractions per second or contractions per minute. The point of posterior process of the pronotum seems to break before the point of the dorsal elevation in individual 11, however, it could have been that the angle of the video did not allow us to observe the real moment of the rupture of the dorsal elevation.

title: Scientific Data Provenance in R: RDataTracker and DDG Explorer

description: Scientific data provenance is the information required to document the history of an item of data, including how it was created and how it was transformed. Data provenance has great potential to improve the transparency, reliability, and reproducibility of scientific results. However it has been little used to date by domain scientists because most systems that collect provenance require scientists to learn specialized software tools and jargon. This project is developing tools that allow scientists to collect, visualize, and query provenance directly from the R statistical language. The first tool (RDataTracker) is a library of R functions that can be downloaded and installed as an R package. RDataTracker allows the scientist to collect data provenance while executing an R script or during an R console session. The resulting provenance is stored on the scientist's computer as a DDG or data derivation graph. The second tool (DDG Explorer) is written in Java and allows the scientist to visualize, store, and query DDGs. Both tools are included in a single install package.

title: Hydraulic Pathways in Leaves of Temperate Trees at Harvard Forest 2002

description: The transport of water, sugar and nutrients in trees is restricted to specific vascular pathways, and thus organs may be relatively isolated from one another (=sectored). Strongly sectored leaf-to-leaf pathways have been shown for the transport of sugar and signal molecules within a shoot, but not previously for water transport. The hydraulic sectoriality of leaf-to-leaf pathways was determined for current year shoots of six temperate deciduous tree species (three ring-porous: Castanea dentata, Fraxinus americana and Quercus rubra, and three diffuse-porous: Acer saccharum, Betula papyrifera and Liriodendron tulipifera). Hydraulic sectoriality was determined using dye staining and a hydraulic method. In the dye method, leaf blades were removed, and dye was forced into the most proximal petiole. For each petiole we counted the vascular traces shared with the proximal petiole. For other shoots, measurements were made of the leaf-area specific hydraulic conductivity for leaf-to-leaf pathways (kLL). In five of six species patterns of sectoriality reflected phyllotaxy; both the sharing of vascular bundles between leaves and kLL were higher for orthostichous than non-orthostichous leaf pairs. Species-differences in leaf-to-leaf sectoriality were determined as the proportional differences between non-orthostichous vs. orthostichous leaf pairs in their staining of shared vascular bundles and in their kLL; for the six species these two indices of sectoriality were strongly correlated (R2 = 0.94; P less than 0.001). Species varied 8-fold in their kLL-based sectoriality, and ring-porous species were more sectored than diffuse-porous species. Differential leaf-to-leaf sectoriality has implications for species-specific coordination of leaf gas exchange and water relations within a branch, especially during fluctuations in irradiance, water and nutrient availability.

title: Anticancer peptide

description: Currently, anticancer peptides (ACPs) are categorized into two distinct types. The first type exhibits cytotoxic effects against bacteria and cancer cells while being non-toxic to normal cells, with notable examples including cecropins and magainins. The second type, represented by insect defensins and tachyplesin II, demonstrates destructive effects on bacteria, cancer cells, and normal cells alike. The non-toxic nature of the first type to normal cells endows them with considerable research significance and prospective applications.In our recent collection, we have focused exclusively on the first type of anticancer peptides. These peptides exhibit diversity in length and sequence, yet most share two common characteristics: cationic and amphipathic properties. Typically composed of 5 to 40 amino acids, these peptides contain arginine, lysine, and histidine, imparting them with a strong cationic nature, as evidenced by their surface net charges ranging from +2 to +9. The structural composition of these peptides, including hydrophilic and hydrophobic side chains, confers them with both hydrophilicity and lipophilicity. Most anticancer peptides possess either α-helical or β-sheet structures, wherein the amphipathic side chains are distributed on either side of the α-helix or concentrated at the extremities, resulting in distinct hydrophilic and hydrophobic faces or ends.This dataset of anticancer peptides, primarily focusing on the first type, is of paramount clinical research and application value. Therefore, we have decided to make this dataset publicly available for the prediction of broad-spectrum pharmacological anticancer peptides. This initiative not only facilitates the exploration of novel anticancer therapeutics but also contributes significantly to the advancement of cancer treatment research.

title: Ecology and Biogeography of a Northern Caddisfly in Cape Cod MA 1996-2002

description: We have documented a large population of a rarely collected northern caddisfly, Phanocelia canadensis (Banks) (Trichoptera: Limnephilidae), on Cape Cod, Massachusetts. This species' range is generally considered to be centered in northern Canada, although there are individual records of adults from eastern Maine and New Hampshire, and a single adult was collected from Sherborn, Massachusetts, in the 1920s. The scarcity of this species in collections may reflect true rarity, with populations sparsely but widely distributed across the northern part of the continent. Alternately, it may reflect a sampling bias, in that the larvae of this species were unknown until the late 1980s, adults are diurnal and fly late in the fall, and larvae occur in wetlands and are closely associated with Sphagnum, from which they make their cases. We have carried out an in-depth habitat comparison of sites in which we found or did not find larvae on Cape Cod in seven years of intensive sampling. Habitat characteristics distinguishing wetlands with and without Phanocelia include dominance by Sphagnum sp., shrub cover, and low pH. We are currently searching in similar habitats across the state for additional populations.

title: Physiological Ecology of Euryhaline Chironomid Midges in Cape Cod MA 2002-2003

description: In summer, 2002, hundreds of thousands of salt-tolerant midges (Chironomus decorus group, Diptera, Chironomidae) emerged from Pilgrim Lake/East Harbor, Truro, MA. The lake is a former estuary but has been separated from the sea for over 150 years by restrictions associated with railroad and highway construction. Brackish conditions caused by leaky tide gates designed to drain excess freshwater from the lake, coupled with high nutrient levels exacerbated by a massive fish kill the previous year, created conditions that supported densities of midge larvae of more than 5,000/m2 and produced a severe public nuisance in the vicinity of the lake when the adult midges emerged. The emergence coincided with National Park Service efforts to increase tidal flow into the lake, as part of a long-term commitment to restoration of restricted coastal waters within the Cape Cod National Seashore. We are studying the effects of increased tidal flow on midge populations, and in particular evaluating how high salinities need to be to reduce the potential for further nuisance outbreaks of the midges.

title: Headwater Habitat Streams in Central Massachusetts 2002-2005

description: Headwater streams, particularly those that flow only during part of the year, are understudied and underprotected in Massachusetts. Research being conducted elsewhere suggests that these "Headwater Habitat Streams" are important both for aquatic biodiversity and for ecological function of lower stream reaches. We are carrying out baseline research, involving research scientists and volunteers, on hydrology and habitat characteristics in headwater streams in northern Worcester County, MA. We hypothesized that headwater streams exhibit a longitudinal gradient of hydrology, from (1) ephemeral channels that flow only in response to storms, through (2) intermittent sections that flow seasonally until the groundwater table falls below the channel and are dry the rest of the year, to (3) interstitial reaches that flow seasonally and retain pools connected by subsurface flow during the summer, to (4) the perennial stream. Results to date show a high degree of longitudinal heterogeneity in the study streams, with interspersion of perennially flowing reaches among low-gradient sections of vegetated wetland, high-gradient boulder piles, and braided channels. Perennial flow is found high up in some watersheds. We expect our methods and results will have implications throughout the Commonwealth for local conservation commissions and other municipal officials responsible for land-use planning and regulation, state agencies responsible for land management and the protection of wildlife, regulators reviewing projects affecting streams, watershed managers, teachers and their students, private land trusts, conservation advocates, and citizen-naturalists.

title: Nitrogen Cycling Dynamics in Sarracenia Purpurea at Harvard Forest 2004-2005

description: In nutrient poor systems, plants employ many strategies in order to acquire and recycle scarce nutrients, including nitrogen. Low leaf N content is associated with low photosynthetic rates, but carnivorous plants have unusually low photosynthetic rates given their N content. The northern pitcher plant Sarracenia purpurea readily uses any available nitrogen: NH4 and NO3 dissolved in precipitation; N mineralized from captured prey; the scant N in saturated peat; and N remobilized from storage. However, the dynamics of N cycling within S. purpurea are poorly understood. We conducted two greenhouse experiments to examine N-cycling dynamics of S. purpurea at the whole-plant and individual-leaf levels. In the first experiment we assessed assimilation, translocation, storage, and remobilization of 15N supplied to pitchers and roots. In the second experiment, we examined how 15N assimilated by the first pitcher produced at the start of the growing season contributed to the production and maintenance of subsequent pitchers, roots, and rhizomes. Patterns of N cycling were similar at the individual-leaf and whole-plant level. Pitchers assimilated 55 - 69% of available 15N and served both as the largest sink for newly assimilated N (more than 90% of the 15N assimilated during 2004) and the largest source of N remobilization the following spring. In contrast, N assimilated by roots was low and accounted for less than 2.5% of the overall S. purpurea N budget. S. purpurea uses both stored N and newly-acquired N throughout the growing season. The importance of stored N decreases throughout the growing season as newly assimilated N contributes more to later pitcher production.

title: Allochthonous Nutrients in the Sarracenia Microecosystem at Harvard Forest 2005-2007

description: Linkages between detritus-based ("brown") food webs and producer-based ("green") food webs are critical components of ecosystem functionality, but these linkages are difficult to study because soil is opaque and brown food webs are poorly characterized. We used the well-defined detritus-based food web that forms in water-filled leaves of the pitcher plant Sarracenia purpurea to directly study how food web structure affects nitrogen (N) transformation and N-uptake by the plant itself. We used isotopically-enriched prey (detritus) and soluble inorganic N to test three predictions of the hypotheses that N uptake efficiency (UE) by S. purpurea is enhanced by the presence of a complete food web in its pitchers: (1) presence of top trophic levels increases UE of prey-derived, but not inorganic, N; (2) UE is contingent on availability of different forms of N; and (3) congeneric Sarracenia species that do not host food webs differ from S. purpurea in UE of prey-derived N. Surprisingly, none of these predictions were borne out in a 3-month greenhouse experiment. We conclude that the higher trophic-level members of this brown food web actively process detritus, but it is the activity of the microbial component of this web that ultimately influences N-availability in S. purpurea.

title: Stream Periphyton Response to Hemlock Mortality in Central Massachusetts 2006

description: The Hemlock Wooly Adelgid (HWA) invasion is expected to cause widespread mortality of eastern hemlock [Tsuga canadensis (L.) Carriere] throughout much of New England. Light levels in streams with hemlock riparian zones are anticipated to increase as hemlock are replaced by deciduous trees. We sought to: 1) quantify differences in light reaching streams with hemlock and deciduous riparian zones, 2) determine if increases in light result in higher periphyton biomass, and 3) explore the role of macroinvertebrate grazing on periphyton biomass as light increases in an attempt to help predict stream ecosystem responses to hemlock mortality. Light measurements were taken along 100-800m stream reaches with riparian zones of healthy hemlock and deciduous trees in MA and CT in order to document an integrated light profile for each stream. In addition, a 2 x 2 factorial experimental design with five replicates was executed on a deciduous reach of Egypt Brook in central MA, in which light (high light vs. low light) and grazing (high grazing vs. low grazing) were manipulated. Light measurements were significantly higher for streams with deciduous riparian zones than hemlock riparian zones. Controlled shading reduced chlorophyll a, while excluding grazing yielded inconclusive results. Periphyton biomass in Egypt Brook was found to be light limited, and grazing did not suppress periphyton biomass. As hemlocks die, in-stream light will be significantly augmented, and periphyton biomass will increase. A challenge for stream ecologists will be to incorporate multiple physical, chemical, and biological controls on biota in order to fully understand how regional hemlock mortality will alter stream periphyton biomass.
