Implications Of Organic Mass To Carbon Ratios Increasing Over Time In The Rural United States, W.C. Malm, B.A. Schichtel, J.L. Hand, A.J. Prenni

United States National Park Service: Publications

The thermal evolution procedure used by most monitoring programs in the United States to determine carbonaceous aerosol concentrations is referred to as the thermal‐optical reflectance method, where an aerosol sample that has been collected on a quartz filter is heated and evolved carbon is characterized as either organic (OC) or light absorbing carbon (LAC). Evolved carbon assigned to OC is multiplied by a factor, Roc, to achieve an estimate of organic mass. Over the last 10–15 years, Roc, estimated through multiple linear regression analysis of data collected in the Interagency Monitoring of Protected Visual Environments (IMPROVE) program, has increased at …

Beneficial Endophytic Bacterial Populations Associated With Medicinal Plant Thymus Vulgaris Alleviate Salt Stress And Confer Resistance To Fusarium Oxysporum, Osama Aballa Abdelshafy Mohamad, Jin-Bao Ma, Yong-Hong Liu, Daoyuan Zhang, Shao Hua, Shirkant Bhute, Brian P. Hedlund, Wen-Jun Li, Li Li

Life Sciences Faculty Research

As a result of climate change, salinity has become a major abiotic stress that reduces plant growth and crop productivity worldwide. A variety of endophytic bacteria alleviate salt stress; however, their ecology and biotechnological potential has not been fully realized. To address this gap, a collection of 117 endophytic bacteria were isolated from wild populations of the herb Thymus vulgaris in Sheikh Zuweid and Rafah of North Sinai Province, Egypt, and identified based on their 16S rRNA gene sequences. The endophytes were highly diverse, including 17 genera and 30 species. The number of bacterial species obtained from root tissues was …

Climate Change Perceptions, Data, And Adaptation In The Garhwal Himalayas Of India, Rutherford V. Platt, Monica V. Ogra, Natalie A. Kisak, Upma Manral, Ruchi Badola

Environmental Studies Faculty Publications

Himalayan communities that depend on rain-fed agriculture are disproportionately vulnerable to climate change. In this study, we compare local perceptions of climate change from a household survey (n = 251) to climate data obtained from the Global Land Data Assimilation System (GLDAS 2.1) and MODIS Terra Snow Cover data product datasets. The study is situated in and around the Kedarnath Wildlife Sanctuary, which is located within the Garhwal Himalayas in the Indian state of Uttarakhand. We found that a large majority of respondents perceive that rainfall is increasing and that snowfall is decreasing, while a smaller majority perceives an …

Berry Important? Wolf Provisions Pups With Berries In Northern Minnesota, Austin T. Homkes, Thomas D. Gable, Steve K. Windles, Joseph K. Bump

United States National Park Service: Publications

Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated.

Probabilistic Hazard Assessment Of Contaminated Sediment In Rivers, Shahab Aldin Shojaeezadeh, Mohammad Reza Nikoo, Ali Mirchi, Iman Mallakpour, Amir Aghakouchak, Mojtaba Sadegh

Civil Engineering Faculty Publications and Presentations

We propose a probabilistic framework rooted in multivariate and copula theory to assess heavy metal hazard associated with contaminated sediment in freshwater rivers that provide crucial ecosystem services such as municipal water source, eco-tourism, and agricultural irrigation. Exploiting the dependence structure between suspended sediment concentration (SSC) and different heavy metals, we estimate the hazard probability associated with each heavy metal at different SSC levels. We derive these relationships for warm (spring-summer) and cold (fall-winter) seasons, as well as stormflow condition, to unpack their nonlinear associations under different environmental conditions. To demonstrate its efficacy, we apply our proposed generic framework to …

Modelling Pinniped Abundance And Distribution By Combining Counts At T Terrestrial Sites And In-Water Sightings, Steven L. Whitlock, Jamie N. Womble, James T. Peterson

United States National Park Service: Publications

Pinnipeds are commonly monitored using aerial photographic surveys at land- or ice-based sites, where animals come ashore for resting, pupping, molting, and to avoid predators. Although these counts form the basis for monitoring population change over time, they do not provide information regarding where animals occur in the water, which is often of management and conservation interest. In this study, we developed a hierarchical model that links counts of pinnipeds at terrestrial sites to sightings-at-sea and estimates abundance, spatial distribution, and the proportion of time spent on land (attendance probability). The structure of the model also allows for the inclusion …

Dental Microwear As A Behavioral Proxy For Distinguishing Between Canids At The Upper Paleolithic (Gravettian) Site Of Predmostí, Czech Republic, Kari A. Prassack, Josephine Dubois, Martina Laznickova-Galetova, Mietje Germonpre, Peter S. Ungar

United States National Park Service: Publications

Morphological and genetic evidence put dog domestication during the Paleolithic, sometime between 40,000 and 15,000 years ago, with identification of the earliest dogs debated. We predict that these earliest dogs (referred to herein as protodogs), while potentially difficult to distinguish morphologically from wolves, experienced behavioral shifts, including changes in diet. Specifically, protodogs may have consumed more bone and other less desirable scraps within human settlement areas. Here we apply Dental Microwear Texture Analysis (DMTA) to canids from the Gravettian site of P�redmostí (approx. 28,500 BP), which were previously assigned to the Paleolithic dog or Pleistocene wolf morphotypes. We test whether …

Sea Wrack Delivery And Accumulation On Islands: Factors That Mediate Marine Nutrient Permeability, Sara B. Wickham, Nancy Shackelford, Chris T. Darimont, Wiebe Nijland, Luba Y. Reshitnyk, John D. Reynolds, Brian M. Starzomski

Biogeography and Ecological Opportunity Collection

Sea wrack provides an important vector of marine-derived nutrients to many terrestrial environments. However, little is known about the processes that facilitate wrack transport, deposition, and accumulation on islands. Three broad factors can affect the stock of wrack along shorelines: the amount of potential donor habitat nearby, climatic events that dislodge seaweeds and transfer them ashore, and physical characteristics of shorelines that retain wrack at a site. To determine when, where, and how wrack accumulates on island shorelines, we surveyed 455 sites across 101 islands in coastal British Columbia, Canada. At each site, we recorded wrack biomass, species composition, and …

Don’T Bite The Hand That Feeds You: Environmental And Human Exploitation Sold As Prosperity, Eliza Macy

Tapestries: Interwoven voices of local and global identities

In this article I focus on corporate power and the false jobs versus human rights dichotomy, extending it to include jobs versus human rights. Using the coal, prison, and oil pipeline industries as examples, the paper explores the ways in which corporate industries gain and maintain local power. I discuss the false narratives and language that industries use to convince people of their importance, showing how they exploit poverty and unemployment to become the single industries dominating localities. Ultimately, this paper demonstrates the fallacy of the jobs versus environment and human rights dichotomy and demonstrates the ways that the coal, …

Immune-Endocrine Links To Gregariousness In Wild House Mice, Patricia C. Lopes, Esther H. D. Carlitz, Morgan Kindel, Barbara König

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Social interactions are critically important for survival and impact overall-health, but also impose costs on animals, such as exposure to contagious agents. The immune system can play a critical role in modulating social behavior when animals are sick, as has been demonstrated within the context of “sickness behaviors.” Can immune molecules affect or be affected by social interactions even when animals are not sick, therefore serving a role in mediating pathogen exposure? We tested whether markers of immune function in both the blood and the brain are associated with gregariousness, quantified as number of animals interacted with per day. To …

The Role Of Climate Change Education On Individual Lifetime Carbon Emissions, Eugene Cordero, Diana Centeno Delgado, Anne Marie Todd

Faculty Publications

Strategies to mitigate climate change often center on clean technologies, such as electric vehicles and solar panels, while the mitigation potential of a quality educational experience is rarely discussed. In this paper, we investigate the long-term impact that an intensive one year university course had on individual carbon emissions by surveying students at least five years after having taken the course. A majority of course graduates reported pro-environmental decisions (i.e., type of car to buy, food choices) that they attributed at least in part to experiences gained in the course. Furthermore, our carbon footprint analysis suggests that for the average …

Ethnic Disparity And Exposure To Supplements Rather Than Adverse Childhood Experiences Linked To Preterm Birth In Pakistani Women, Kiran Shaikh, Shahirose Sadrudin Premjib, Sharifa Bashir Lalani, Ntonghanwah Forcheh, Aliyah Dosanic, Ilona S. Yim, Pauline Samia, Christopher Naugler, Nicole Letourneau, The Maternal Infant Global Health Team (Might) Collaborators In Research

Paediatrics and Child Health, East Africa

Background: Adverse childhood experiences (ACEs) are associated with prenatal mental health and negative pregnancy outcomes in high income countries, but whether the same association exists in Pakistan, a low- to middle-income (LMI) country, remains unclear.

Methods: Secondary data analyses of a prospective longitudinal cohort study examining biopsychosocial measures of 300 pregnant women at four sites in Karachi, Pakistan. A predictive multiple logistic regression model for preterm birth (PTB; i.e., <37 weeks’ gestation) was developed from variables significantly (P < 0.05) or marginally (P < 0.10) associated with PTB in the bivariate analyses.

Results: Of the 300 women, 263 (88%) returned for delivery and were included in the current analyses. The PTB rate was 11.1%. We found no association between ACE and PTB. Mother's …

As a biology major at New York University, I was introduced to ecology in a course that bused the class out of New York University's Greenwich Village campus every weekend, to investigate biodiversity patterns in nearby forests and wetlands. After a day crossing bogs and walking through forests, I would take the subway home, hip boots in hand, reflecting on how the day's activities connected to my routine city life. Engaging others in understanding the city connections to adjacent habitats became my life's work. As Dean of Arts and Sciences at a public liberal arts university, I encourage faculty and …
