title: Designing Sustainable Landscapes: Watershed habitat loss, watershed imperviousness, road salt, sediment, nutrients, and dam intensity metrics

description: This document describes a suite of stressor metrics that assess the various effects of development in the watershed of the focal cell, as opposed to a (usually) circular window around the focal cell, as with the other metrics. These metrics are used for lotic, lentic, and wetland systems. All effects are weighted by a the time of flow from each stressor source to the focal cell, thus, stressor sources that fall within a stream have a greater effect than those in distant uplands within the watershed. These share a common algorithm, but each has unique parameters. These metrics are elements of the ecological integrity analysis of the Designing Sustainable Landscapes (DSL) project (see technical document on integrity, McGarigal et al 2014). Consisting of a composite of 21 stressor and resiliency metrics, the index of ecological integrity (IEI) assesses the relative intactness and resiliency to environmental change of ecological systems throughout the northeast. These stressor metrics range from 0 (no effect) to maximum values that differ for each metric (severe effect). See Table 1 for parameters for each metric.

title: Limits of economy and fidelity for programmable assembly of size-controlled triply-periodic polyhedra

description: We propose and investigate an extension of the Caspar-Klug symmetry principles for viral capsid assembly to the programmable assembly of size-controlled triply-periodic polyhedra, discrete variants of the Primitive, Diamond, and Gyroid cubic minimal surfaces. Inspired by a recent class of programmable DNA origami colloids, we demonstrate that the economy of design in these crystalline assemblies -- in terms of the growth of the number of distinct particle species required with the increased size-scale (e.g. periodicity) -- is comparable to viral shells. We further test the role of geometric specificity in these assemblies via dynamical assembly simulations, which show that conditions for simultaneously efficient and high-fidelity assembly require an intermediate degree of flexibility of local angles and lengths in programmed assembly. Off-target misassembly occurs via incorporation of a variant of disclination defects, generalized to the case of hyperbolic crystals. The possibility of these topological defects is a direct consequence of the very same symmetry principles that underlie the economical design, exposing a basic tradeoff between design economy and fidelity of programmable, size controlled assembly.

title: Designing Sustainable Landscapes: Probability of Development

description: The integrated probability of development (probDevelop) is derived from an extraordinarily complex urban growth model described in detail in the technical document on urban growth (McGarigal et al 2017). The urban growth model is one of the major landscape change drivers in our Landscape Change, Assessment and Design (LCAD) model, in which it functions to simulate the stochastic growth of low-, moderate- and highintensity development during each 10-year timestep of a 70-year simulation between 2010- 2080. Because the urban growth model simulates the spatial footprint of development as a stochastic process, the development that occurs in any one simulation is merely a single stochastic realization of what could happen. Thus, any single urban growth realization is not particularly useful in landscape design. Instead, we developed this product to represent the integrated probability of development occurring between 2010-2080, which accounts for the type (low-, medium-, and high-intensity), amount and spatial pattern of development. This index represents the probability of development integrated across all of the possible development transitions occurring sometime between 2010 and 2080 at the 30 m cell level.

title: Massachusetts Beach Grain Size and Slope Data

description: This data repository contains grain size and beach face slope data from approximately 100 paired summer and winter transects collected along 18 separate beaches in southern New England. The study is focused to beaches of Massachusetts, which represents a particularly unique section of the Northeastern US coast in that it: 1) lies at the interface between New England’s paraglacial lowlands and Mid-Atlantic Coastal Plain, 2) spans both micro- and meso- tidal regimes, 3) encompasses a wide range of seasonally varying wave conditions, and 4) contains a diverse array of geomorphic and grain size characteristics. Between 2 and 10 intertidal transects were conducted for each of the sites depending on the length of the beach and accessibility. Transect positions were chosen at representative locations along the beach and equally spaced when possible. At each transect at least three separate samples were collected at near 1) high-tide, 2) mid-tide and 3) low-tide. When possible, additional samples were collected along berm crest, storm berms and dune. To assess seasonal variations in grain size distribution and slope, all transects along beaches were sampled and surveyed twice, once at the end of the summer and then revisited again at the end of the winter season. Surface sediments from the top 15-30 cm were collected from sites primarily composed of sand and pebbles (i.e. &lt; 64 mm), and brought back to the University of Massachusetts in Amherst, MA for analysis. Exclusively sand samples were collected in 1-liter (1-quart) bags, predominantly sand samples were collected in 4-liter (1-gallon) bags and mixed sand and pebble samples in 19 -liter (5 gallon) buckets. Areas comprised primarily of cobbles and boulder (&gt; 64 mm) were measured in the field using a gravelometer and standard pebble count technique. Sediment samples were washed and dried thoroughly to remove salt and debris (sticks, seaweed, etc.). Each sample was weighed and sub-divided into fractions greater and less than 4 mm. Distributions for grains greater than 4 mm were obtained via standard sieving techniques. Grain size distributions for sample fractions &lt; 4 mm were measured on a CAMSIZER digital particle size analyzer capable of measuring particles between 30 μm and 4 mm. The elevation of each sampling location as well as inter-tidal beach slope for each transect was obtained using a using a Real Time Kinematic (RTK) GPS survey system or a total station survey system tied to local benchmarks.

title: Designing Sustainable Landscapes: aquatic barriers settings variable

description: Aquatic barriers is one of several ecological settings variables that collectively characterize the biophysical setting of each 30 m cell at a given point in time (McGarigal et al 2017). Aquatic barriers measures the relative degree to which road-stream crossings (i.e., bridges and culverts) and dams may physically impede upstream and downstream movement of aquatic organisms, particularly fish. It is derived from a custom algorithm (see below for details) applied to dams and derived road-stream crossings. Briefly, each dam has an aquatic barrier score based either on dam height or attributes indicating whether the dam has a partial/complete breach. Similarly, each road-stream crossing has an aquatic barrier score based either on an algorithm applied to field measurements of the crossing structure or predictions from a statistical model based on GIS data. Aquatic barriers is scaled 0-1, where dams and road-stream crossing are assigned values &gt;0 (with 1=complete barrier) and all other cells (including terrestrial) are assigned 0.

title: Designing Sustainable Landscapes: CaCO3 content settings variable

description: Calcium carbonate (CaCO3) content is one of several ecological settings variables that collectively characterize the biophysical setting of each 30 m cell at a given point in time (McGarigal et al 2017). CaCO3 buffers acidity in soil and water, increasing nutrient uptake by plants, and providing a ready source of calcium for organisms such as aquatic insects. CaCO3 content (Fig. 1), affects the composition of natural communities both directly and indirectly, such that areas with high calcium have increased species richness and support a number of unique species.

title: Designing Sustainable Landscapes: Salt Marsh Ditching Metric

description: The majority of salt marsh ditches in the Northeast have been ditched, both to facilitate harvest of salt marsh hay and to control mosquitoes (Smith and Niles 2016). Ditching changes the hydrology and flows of sediment and nutrients of marshes in ways that are not well understand, though ditched marshes may have altered invertebrate and shorebird communities, and may be less resilient to sea level rise (LeMay 2007). Marshes with intensive ditching (ca. 10 m spacing) appear to be most strongly affected (Vincent et al. 2013). The salt marsh ditching metric is an element of the ecological integrity analysis of the Designing Sustainable Landscapes (DSL) project (see technical document on integrity, McGarigal et al 2017). Consisting of a composite of 21 stressor and resiliency metrics, the index of ecological integrity (IEI) assesses the relative intactness and resiliency to environmental change of ecological systems throughout the northeast. As a stressor metric, salt marsh ditching provides an index of the relative intensity of ditching in salt marshes. Metric values range from 0 (no effect from nearby ditches) to 1 (severe effect). The metric is based on a custom image analysis process that identifies most ditches in salt marshes throughout the northeast from 1 m LiDAR (Light Detection And Ranging)-based DEMs (Digital Elevation Models). The algorithm, uses a kernel to identify local depressions that could be ditches. It then uses a morphological skeletonize algorithm to draw a 1 m-wide line through the middle of depressions, and then uses an original approach, “clockfacing,” to find linear features in these centerlines of depressions and connect disconnected sections. These potential ditches are converted from raster to linear features, and long, fairly straight sections are tagged as ditches. These linear ditches are converted back to a 1 m raster, then to a 30 m raster, with a value indicating ditch density in each cell. Finally, the ditching metric itself measures the intensity of ditches in the neighborhood of each salt marsh cell using a kernel estimator. Funding for this project was provided by the North Atlantic Landscape Conservation Cooperative and Department of the Interior Project #24, Decision Support for Hurricane Sandy Restoration and Future Conservation to Increase Resiliency of Tidal Wetland Habitats and Species in the Face of Storms and Sea Level Rise.

title: Data and R code for "Gut Transplants from Bees Fed an Antipathogenic Pollen Diet Do Not Confer Pathogen Resistance to Recipients"

description: Pollinators are threatened by diverse stressors, including microbial pathogens such as Crithidia bombi. Consuming sunflower pollen dramatically reduces C. bombi infection in the bumble bee Bombus impatiens, but the mechanism behind this medicinal effect is unclear. We asked whether diet mediates resistance to C. bombi through changes in the gut microbiome. We hypothesized that sunflower pollen changes the gut microbiome, which in turn reduces Crithidia infection. To test this, we performed a gut transplant experiment. We fed donor bees either a sunflower pollen treatment or buckwheat pollen as a control treatment, and then inoculated recipient bees with homogenized guts from either sunflower-fed or buckwheat-fed donor bees. All recipient bees were then fed a wildflower pollen diet. Two days after the transplant, we infected recipients with C. bombi, and two days later, we provided another donor gut transplant. To quantify infection, we performed both fecal screens and dissections of the recipient bees. We found no significant differences in C. bombi infection intensity or presence between bees that received sunflower-fed microbiomes versus buckwheat-fed microbiomes. This suggests that sunflower pollen's effects on pathogen resistance are not mediated by gut microbiota.

title: Designing Sustainable Landscapes: Critical Local Linkages

description: Critical local linkages includes two Designing Sustainable Landscapes (DSL) products that measure the relative potential to improve local aquatic connectivity through restoration, including dam removals and culvert upgrades. A complete description of the critical local linkage assessment is provided in the technical document on connectivity (McGarigal et al 2017. Here, we briefly describe the dam removal and culvert upgrade layers. These particular products were initially developed for the Connecticut River watershed as part of the Connect the Connecticut project (www.connecttheconnecticut.org) — a collaborative partnership under the auspices of the North Atlantic Landscape Conservation Cooperative (NALCC), and subsequently developed for the entire Northeast region as part of the Nature's Network project (www.naturesnetwork.org). Briefly, each dam or road-stream crossing is scored based on its potential to improve local connectivity through the corresponding restoration action, but only where it matters — in places where the current ecological integrity is not already seriously degraded too much.
