Macroalgae Aquaculture in Southwestern Florida as a Potential Tool for Nutrient Sequestration

In many coastal areas, excess nutrients from terrestrial sources have led to rapid growth in dead zones and degradation. Macroalgae is well-known for ecosystem services including nutrient sequestration and can be used to restore eutrophic waterways, while simultaneously creating economic opportunities through aquaculture practices. To determine the viability of macroalgae aquaculture in Sanibel, Florida, three testing sites along with two different treatments (enclosed vs. exposed) were established. All testing sites were equipped with two macroalgae aquaculture lines that featured clusters of macroalgae attached by fishing line, as well as macroalgae samples enclosed in mesh bags. The goal of this project was to see which method would lead to the greatest amount of algal growth, as well as what treatments were the most influential for aquaculture success in Tarpon Bay. Coastal discharge sites are the optimal location for pollution accumulation. Efforts, such as macroalgae aquaculture, are being studied to determine aquaculture’s viability in sequestering harmful nutrients in these areas. However, the use of freshwater macroalgae has the potential to also clean water upstream before its final disposal in the ocean. The next step for this project is to begin testing the viability of freshwater macroalgae, and its impacts, on degraded freshwater ponds in Eastern Iow

Solar absorption chiller

In developing nations access to electricity is inconsistent at best, and food spoilage is a prevalent issue. The solar powered absorption chiller is a refrigeration system designed to provide refrigeration to these developing areas. This year, our team has worked to develop a system where the sun\u27s rays are collected as heat to power an absorption refrigerator. The goal of this project was to take an existing solar tracker system and use its collected heat to power a refrigerator. Our team designed and built heat exchangers to extract heat from the concentrated solar system; assembled components for a fluid circulation loop; and retrofitted an absorption chiller refrigerator to be powered by our heated fluid. Additionally, we redesigned an existing solar tracking system to improve function and decrease power consumption. By the end of this year we assembled the entire system and performed months of solar testing as well as proof-ofconcept testing that the refrigerator could receive necessary heat through a heated fluid. By the end of the school year, we concluded that the heated fluid would need to reach 150°C to begin the refrigeration cycle (with current heat exchanger design), which was 25° higher than our solar testing had achieved. With further improvements, the refrigerator could be designed to run with lower heat inputs and the tracker system could be designed to attain heat at higher temperatures. With these changes, a working refrigeration system could have dramatic impacts on farming communities in developing countries; reducing food spoilage, increasing family income, and preventing food-borne illnesses

Psychosocial Impacts of the COVID-19 Pandemic: The Role of Men’s Gender-Related Attitudes, Employment and Housework, and Demographic Characteristics

Background and objective: Globally, men are at greater risk of mortality and serious physical consequences from COVID-19 infection than women, but are less impacted by the pandemic’s impact on labor force participation and increased childcare responsibilities. Outside of gender identity, however, it is unclear whether men’s beliefs about gender may be related to the kinds of COVID-19-related impacts they report. This study sought to describe the employment, income, and household responsibility-related impacts of the pandemic on a sample of young men in the U.S. and to examine relationships between the men’s gender ideologies and attitudes toward gender equity with self-reported stress impacts of the pandemic. Methods: The data are from an online survey of 481 young men from across the U.S. Measures included scales assessing masculinity ideology, modern sexism, support for traditional divisions of labor by gender, and attitudes toward gender equity. New items developed for this study assessed COVID-19-related changes in employment, household responsibilities, and childcare duties as well as levels of stress. Hierarchical regression examined the relative roles of demographic characteristics, changes in employment and household work, and gender-related attitudes on COVID-related stress. Results: Descriptive findings showed that under 50% of the men in the sample experienced negative COVID-related impacts on employment, but that a majority of the men reported at least some COVID-related stress. Results of the hierarchical regression suggest that higher levels of stress were predicted by having a minoritized sexual identity, less religiosity, experiencing employment or household responsibility-related changes, and not endorsing modern sexism or a traditional, gendered division of labor. Conclusions: Experiencing COVID-19-related stress was normative in this sample of young men. However, endorsing traditional notions of a gendered division of labor was slightly protective against higher levels of COVID-related stress. These findings add to existing evidence that gender analysis must be a central component of ongoing COVID-related policy and programming development

Carbon Finance II: Investing in Forests for Climate Protection

Carbon Finance II: Investing in Forests for Climate Protection is a collection of lectures given during the 2008-2009 Carbon Finance Speaker Series at the Yale School of Forestry & Environmental Studies. The annual series is hosted by the Center for Business and the Environment at Yale and supported by the Emily Hall Tremaine Foundation and the Henry P. Kendall Foundation. The 2008-2009 speaker series focused on forest carbon and the opportunities and obstacles to including forests in greenhouse gas emission reduction policies, carbon markets, and cap-and-trade systems

Effect of oil palm sustainability certification on deforestation and fire in Indonesia.

Many major corporations and countries have made commitments to purchase or produce only "sustainable" palm oil, a commodity responsible for substantial tropical forest loss. Sustainability certification is the tool most used to fulfill these procurement policies, and around 20% of global palm oil production was certified by the Roundtable on Sustainable Palm Oil (RSPO) in 2017. However, the effect of certification on deforestation in oil palm plantations remains unclear. Here, we use a comprehensive dataset of RSPO-certified and noncertified oil palm plantations (∼188,000 km2) in Indonesia, the leading producer of palm oil, as well as annual remotely sensed metrics of tree cover loss and fire occurrence, to evaluate the impact of certification on deforestation and fire from 2001 to 2015. While forest loss and fire continued after RSPO certification, certified palm oil was associated with reduced deforestation. Certification lowered deforestation by 33% from a counterfactual of 9.8 to 6.6% y-1 Nevertheless, most plantations contained little residual forest when they received certification. As a result, by 2015, certified areas held less than 1% of forests remaining within Indonesian oil palm plantations. Moreover, certification had no causal impact on forest loss in peatlands or active fire detection rates. Broader adoption of certification in forested regions, strict requirements to avoid all peat, and routine monitoring of clearly defined forest cover loss in certified and RSPO member-held plantations appear necessary if the RSPO is to yield conservation and climate benefits from reductions in tropical deforestation

How Important Are Data Curation Activities to Researchers? Gaps and Opportunities for Academic Libraries

Introduction: Data curation may be an emerging service for academic libraries, but researchers actively “curate” their data in a number of ways—even if terminology may not always align. Building on past user-needs assessments performed via survey and focus groups, the authors sought direct input from researchers on the importance and utilization of specific data curation activities. Methods: Between October 21, 2016, and November 18, 2016, the study team held focus groups with 91 participants at six different academic institutions to determine which data curation activities were most important to researchers, which activities were currently underway for their data, and how satisfied they were with the results. Results: Researchers are actively engaged in a variety of data curation activities, and while they considered most data curation activities to be highly important, a majority of the sample reported dissatisfaction with the current state of data curation at their institution. Discussion: Our findings demonstrate specific gaps and opportunities for academic libraries to focus their data curation services to more effectively meet researcher needs. Conclusion: Research libraries stand to benefit their users by emphasizing, investing in, and/or heavily promoting the highly valued services that may not currently be in use by many researchers

Data Curation Network: How Do We Compare? A Snapshot of Six Academic Library Institutions’ Data Repository and Curation Services

Objective: Many academic and research institutions are exploring opportunities to better support researchers in sharing their data. As partners in the Data Curation Network project, our six institutions developed a comparison of the current levels of support provided for researchers to meet their data sharing goals through library-based data repository and curation services. Methods: Each institutional lead provided a written summary of their services based on a previously developed structure, followed by group discussion and refinement of descriptions. Service areas assessed include the repository services for data, technologies used, policies, and staffing in place. Conclusions: Through this process we aim to better define the current levels of support offered by our institutions as a first step toward meeting our project\u27s overarching goal to develop a shared staffing model for data curation across multiple institutions

Spatial parasitology and the unmapped human helminthiases

Helminthiases are a class of neglected tropical diseases that affect at least 1 billion people worldwide, with a disproportionate impact on resource-poor areas with limited disease surveillance. Geospatial methods can offer valuable insights into the burden of these infections, particularly given that many are subject to strong ecological influences on the environmental, vector-borne or zoonotic stages of their life cycle. In this study, we screened 6829 abstracts and analysed 485 studies that use maps to document, infer or predict transmission patterns for over 200 species of parasitic worms. We found that quantitative mapping methods are increasingly used in medical parasitology, drawing on One Health surveillance data from the community scale to model geographic distributions and burdens up to the regional or global scale. However, we found that the vast majority of the human helminthiases may be entirely unmapped, with research effort focused disproportionately on a half-dozen infections that are targeted by mass drug administration programmes. Entire regions were also surprisingly under-represented in the literature, particularly southern Asia and the Neotropics. We conclude by proposing a shortlist of possible priorities for future research, including several neglected helminthiases with a burden that may be underestimated

Natural Analogue Constraints on Europa's Non-ice surface Material

Non-icy material on the surface of Jupiter’s moon Europa is hypothesised to have originated from its subsurface ocean, and thus provide a record of ocean composition and habitability. The nature of this material is debated, but observations suggest that it comprises hydrated sulfate and chloride salts. Analogue spectroscopic studies have previously focused on single phase salts under controlled laboratory conditions. We investigated natural salts from perennially cold (<0 °C) hypersaline springs, and characterised their reflectance properties at 100 K, 253 K and 293 K. Despite similar major ion chemistry, these springs form mineralogically diverse deposits, which when measured at 100 K closely match reflectance spectra from Europa. In the most sulfate-rich samples, we find spectral features predicted from laboratory salts are obscured. Our data are consistent with sulfate-dominated europan non-icy material, and further, show that the emplacement of endogenic sulfates on Europa’s surface would not preclude a chloride-dominated ocean
