The River Process Corridor: A Modular River Assessment Method Based On Process Units And Widely Available Data In The Northeast Us., John D. Gartner, Christine E. Hatch, Eve Vogel, Et. Al.

Water Reports

We define the river process corridor (RPC) as the area adjacent to a river that is likely to affect and be affected by river and floodplain processes. Here we present a novel approach for delineating the RPC that utilizes widely available geospatial data, can be applied uniformly across broad and multi-scalar spatial extents, requires relatively low levels of expertise and cost, and allows for modular additions and adaptations using additional data that is available in particular areas. Land managers are increasingly using a variety of delineated river and floodplain areas for applied purposes such as hazard avoidance, ecological conservation, and …

Environmental Decision-Making (Nrc 494 Ei), Ezra Markowitz

Sustainability Education Resources

Over the past 30 years, there has been a growing recognition amongst environmental advocates, resource managers, policymakers and researchers that the underlying cause of most environmental, conservation and sustainability issues is human behavior. As NRC and ENVIRSCI majors, you have received extensive technical training in how natural systems operate yet relatively little training when it comes to influencing or understanding how people make environmental decisions that affect those natural systems. Recognizing the fundamental role that human decision-making plays in shaping the environment reveals a new set of tools and approaches for both understanding the challenges we face and confronting those …

Architecture Now: A History Of Sustainable Architecture, Meg Vickery

Sustainability Education Resources

As we move further into the 21st century, architects, planners, landscape architects and the general public are increasingly concerned with climate change, environmental degradation, energy and water consumption and the role the built environment plays in contributing to or addressing these issues. Buildings consume almost 40% of the energy used in this country. The way we access buildings, the materials used to construct them, the demands of users within the building all require the earth’s increasingly precious resources. So how did we get here? How did our built environment evolve to require so much energy, water and so many resources? …

Accessible Science: The Natural History Of The Connecticut River Valley, Fred Venne

Science and Engineering Saturday Seminars

Many students take an Earth science or geology course to fulfill a requirement, knowing little to nothing about the field. Like all sciences, geology can appear to have ready answers unconnected to other areas of human endeavor, such as art, religion or philosophy. An interdisciplinary approach to teaching can ameliorate this perception for students who are intimidated by the subject and deepen understanding for those who are already excited about geology. We will examine two strategies designed to support the nature of science while scaffolding student learning in geology: research based digital resources use and museum of natural history visits. …

Flavonoid Intake And Plasma Sex Steroid Hormones, Prolactin, And Sex Hormone-Binding Globulin In Premenopausal Women, You Wu, Susan E. Hankinson, Stephanie A. Smith-Warner, Molin Wang, A. Heather Eliassen

Biostatistics and Epidemiology Faculty Publications Series

Background: Flavonoids potentially exert anti-cancer effects, as suggested by their chemical structures and supported by animal studies. In observational studies, however, the association between flavonoids and breast cancer, and potential underlying mechanisms, remain unclear. Objective: To examine the relationship between flavonoid intake and sex hormone levels using timed blood samples in follicular and luteal phases in the Nurses’ Health Study II among premenopausal women. Methods: Plasma concentrations of estrogens, androgens, progesterone, dehydroepiandrosterone (DHEA), DHEA sulfate (DHEAS), prolactin, and sex hormone-binding globulin (SHBG) were measured in samples collected between 1996 and 1999. Average flavonoid were calculated from semiquantitative food frequency questionnaires …

Disentangling The Abundance–Impact Relationship For Invasive Species, Bethany A. Bradley, Brittany B. Laginhas, Raj Whitlock, Jenica M. Allen, Amanda E. Bates, Genevieve Bernatchez, Jeffrey M. Diez, Regan Early, Jonathan Lenoir, Montserrat Vilà, Cascade J.B. Sorte

Environmental Conservation Faculty Publication Series

To predict the threat of biological invasions to native species, it is critical that we understand how increasing abundance of invasive alien species (IAS) affects native populations and communities. The form of this relationship across taxa and ecosystems is unknown, but is expected to depend strongly on the trophic position of the IAS relative to the native species. Using a global metaanalysis based on 1,258 empirical studies presented in 201 scientific publications, we assessed the shape, direction, and strength of native responses to increasing invader abundance. We also tested how native responses varied with relative trophic position and for responses …

Effects Of Urbanization On Native Bird Species In Three Southwestern Us Cities, Christopher B. Hensley, Christopher H. Trisos, Paige S. Warren, Jennie Macfarland, Steve Blumenshine, Joshua Reece, Madhusudan Katti

Environmental Conservation Faculty Publication Series

Urbanization presents novel challenges to native species by altering both the biotic and abiotic environment. Studies have attempted to make generalizations about how species with similar traits respond to urbanization, although existing results are idiosyncratic across cities and often fail to account for seasonality. Here, we present a comparative study in three US cities: Fresno, California; Tucson, Arizona; and Phoenix, Arizona. Using presence-absence data to define regional bird species pools and urban assemblages in non-breeding (winter) and breeding (spring) seasons, we tested whether urban avian assemblages were a random subset of regional assemblages on the basis of both traits and …

Visual Head Counts: A Promising Method For Efficient Monitoring Of Diamondback Terrapins, Patricia Levasseur, Sean Sterrett, Chris Sutherland

Environmental Conservation Faculty Publication Series

Determining the population status of the diamondback terrapin (Malaclemys terrapin spp.) is challenging due to their ecology and limitations associated with traditional sampling methods. Visual counting of emergent heads offers a promising, efficient, and non-invasive method for generating abundance estimates of terrapin populations across broader spatial scales than has been achieved using capture–recapture, and can be used to quantify determinants of spatial variation in abundance. We conducted repeated visual head count surveys along the shoreline of Wellfleet Bay in Wellfleet, Massachusetts, and analyzed the count data using a hierarchical modeling framework designed specifically for repeated count data: the N-mixture model. …

Accounting For Aboveground Carbon Storage In Shrubland And Woodland Ecosystems In The Great Basin, Emily J. Fusco, Benjamin M. Rau, Michael Falkowski, Steven Filippelli, Bethany A. Bradley

Environmental Conservation Faculty Publication Series

Improving the accuracy of carbon accounting in terrestrial ecosystems is critical for understanding carbon fluxes associated with land cover change, with significant implications for global carbon cycling and climate change. Semi‐arid ecosystems account for an estimated 45% of global terrestrial ecosystem area and are in many locations experiencing high degrees of degradation. However, aboveground carbon accounting has largely focused on tropical and forested ecosystems, while drylands have been relatively neglected. Here, we used a combination of field estimates, remotely sensed data, and existing land cover maps to create a spatially explicit estimate of aboveground carbon storage within the Great Basin, …

Pregnancies, Abortions, And Pregnancy Intentions: A Protocol For Modeling And Reporting Global, Regional And Country Estimates, Jonathan Marc Bearak, Anna Popinchalk, Gilda Sedgh, Bela Ganatra, Ann-Beth Moller, Özge Tunçalp, Leontine Alkema

Biostatistics and Epidemiology Faculty Publications Series

Background

Estimates of pregnancies, abortions and pregnancy intentions can help assess how effectively women and couples are able to fulfil their childbearing aspirations. Abortion incidence estimates are also a necessary foundation for research on the safety of abortions performed and the consequences of unsafe abortion. Furthermore, periodic estimates of these indicators are needed to help inform policy and programmes.

Methods

We will develop a Bayesian hierarchical times series model which estimates levels and trends in pregnancy rates, abortion rates, and percentages of pregnancies and births unintended for each five-year period between 1990 and 2019. The model will be informed by …
