Understanding And Managing Karst Water Resources In Belize: Case Studies Of Both Past And Present In A Changing Climate, Jason S. Polk, Leslie A. North, Ben Miller, Jonathan Oglesby, Kegan Mcclanahan, Lowell Neeper, Aaron Holland, Bernie Strenecky

National Cave and Karst Management Symposium 2013

Belize is a developing country that faces water resource issues in the forms of both quality and quantity, stemming from a long history of environmental stress and population threats, from the ancient Maya to present. Belize’s karst landscape, which comprises a large part of the country from the coast to the Maya Mountains, is characterized by springs, caves, sinkholes, and aquifers systems formed from the dissolution of carbonate (limestone, dolomite) rock. This research presents several different case studies, spanning from the ancient Maya and issues with drought to modern communities that rely on groundwater resources quickly being depleted. Past drought …

The Nps Cave Visitor Impact Vital Signs Monitoring Protocol, Rodney Horrocks

National Cave and Karst Management Symposium 2013

The national Cave Visitor Impact Vital Signs Monitoring Protocol is an attempt to standardize visitor impact monitoring in all National Park Service managed caves. With standardized monitoring in place, it will be feasible for the first time to compare monitoring data from caves across the country. This cave monitoring protocol was initiated at the NPS Cave Vital Signs Workshop held in Lakewood, Colorado in 2008. That workshop identified the vital signs that were common to all caves, including cave visitor impact. A committee convened at that workshop decided that the cave visitor impact monitoring protocol would address four parameters of …


Global Change Factors On Ecosystem Invasibility, Raj Lal, Jeffrey Dukes, Michael J. Schuster, Nick G. Smith Oct 2013

Global Change Factors On Ecosystem Invasibility, Raj Lal, Jeffrey Dukes, Michael J. Schuster, Nick G. Smith

The Summer Undergraduate Research Fellowship (SURF) Symposium

Current climate and human-induced changes are projected to alter many regimes of ecosystem functioning. It is projected that invasive species, nonnative species that can be of great detriment to an ecosystem, will benefit under these conditions. The Prairie Invasion and Climate Experiment (PRICLE) studies the effects of two global change factors – N addition and altered precipitation – on invasive species success and the traits that are selected for in a mixed-grass prairie ecosystem. PRICLE is a two by two factorial design over three replications in a restored mixed-grass prairie ecosystem. The major findings from the community traits examination of …

Rescuing biochar: Pre - application techniques to enhance plant responses to biochar additions: Nigel Gale, U of Toronto

A growing body of literature indicates variable responses of different plant species to biochar, including positive, neutral, and negative, suggesting that it is important to investigate the nature and mechanism of species-specific responses to biochar additions. Neutral or negative plant responses to additions of biochars have commonly been reported in prior studies, and are likely the result of a combination of changes in soil properties (e.g. pH, surface area, and nutrient and water retention) and the production of volatile organic compounds from …

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute

In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing …

Ethics & Sustainability, Gloria Flora, John Bonitz, Karen Ribeiro

USBI Biochar Conferences

Biochar and the Sustainability Imperative. Now marks a critical time: as biochar comes of age and markets begin to develop, this young industry is attracting naysayers, doubters and get-rich-quick-schemers. Ethical biochar production and use is of paramount importance as we continue to lay the groundwork for biochar as a model for carbon neutral/negative business, landscape restoration and truly green technology. Shortcuts, poor quality product and unsustainable use of biomass could bring biochar to its knees before it gains the traction necessary to fulfill its promises. This discussion will explore opportunities and pitfalls in feedstocks sustainability, production integrity and ethics in …

Sorptive Treatment of Metals and Nitro Explosives in Water Using Biochar -

Seok-Young Oh1*,

Biochar, a solid byproduct of a pyrolysis process was investigated as a sorbent to remove toxic metals and nitro explosives from natural water and wastewater. It was hypothesized that biochar can sorb dissolved metals and nitro explosives due to its high surface area and strong sorption affinity of aromatic organic compounds. Using a tube furnace under N2, various types biochar were synthesized by changing biomass (poultry litter, sludge, fallen leaves, corn stalk, rice straw, and coffee grounds) and temperature (250, 400, …

A Preliminary Assessment Of Speleothem Sampling Methods For Paleoclimate Research, Sarah Truebe Sep 2013

A Preliminary Assessment Of Speleothem Sampling Methods For Paleoclimate Research, Sarah Truebe

National Cave and Karst Management Symposium 2013

Speleothems are incomparable archives of paleoclimate information. Most methods to extract past climate information from speleothems are necessarily destructive; sampling must occur along the growth axis. Development of sustainable methods for sampling these nonrenewable resources, whereby the needs of science and cave conservation are balanced, ought to be a priority of the paleoclimate community. Ergo, I am studying currently practiced methods in the field of speleothem paleoclimatology. Part 1 of this two-part study entails surveying active speleothem paleoclimatology labs nationally and internationally. The results of this portion of the survey will be converted to an anonymous list of current methods …

Incorporating Satellite Derived Cloud Climatologies To Improve High Resolution Interpolation Of Daily Precipitation., Adam M. Wilson, Benoit Parmentier, Brian Mcgill, Rob Guralnick, Walter Jetz

Yale Day of Data

Conservation of biodiversity demands comprehension of evolutionary and ecological patterns and processes that occur over vast spatial and temporal scales. A central goal of ecology is to understand the factors that control the spatial distribution of species and this has become even more important in the face of climate change. However, at global scales there can be enormous uncertainty in environmental data used to model species distributions. Even ‘simple’ metrics such as mean annual precipitation are difficult to estimate in areas with few weather stations and available data sets do not quantify uncertainty in these surfaces. We are developing a …

New N-Nitrosodimethylamine (Ndma) Precursors That React With Ozone: Implications For Water Reuse, Erica Marti, Aleks Pisarenko, Eric Dickenson Apr 2013

New N-Nitrosodimethylamine (Ndma) Precursors That React With Ozone: Implications For Water Reuse, Erica Marti, Aleks Pisarenko, Eric Dickenson

College of Engineering: Graduate Celebration Programs

Ozonation is a promising treatment step for water reuse. Compared to the “gold standard” with reverse osmosis and advanced oxidation, ozone requires less energy and does not result in a waste brine. This makes ozone more cost-effective. However, the formation of nitrosamines may be a significant barrier to the use of ozonation in water reuse applications, particularly for potable reuse.

Solar Cell Design Using Metamaterials, Yang Liu, Yitung Chen, Jichun Li

College of Engineering: Graduate Celebration Programs

Natural structure with simultaneous negative permittivity and permeability has not been discovered yet. However, using specially-designed metal embedded in dielectric bodies can achieve a kind of artificial negative index. This periodic structure which is smaller than the guided wavelength is known as a metamaterial. However, recent designs of metamaterials have some disadvantages when they are used in the application of solar cell. The perfect absorption is only within a narrow band, and for most of the solar spectrum, the absorption is no more than 10%. Here, a new kind of absorber for the solar spectrum has been designed and analyzed, …
