Pollinator Habitat Availability And Diversity In Various Tropical Agroforestry Management Systems Of Coffea Arabica In Santa Clara, Chiriqui, Julia Brokaw

Independent Study Project (ISP) Collection

Habitat loss due to increasing agricultural intensification and chemical use may result in the loss of biodiversity of bee species. This has implications for global economies and food security for people world wide. Focusing on coffee cultivation, an important cash crop in the tropics, this study aims to understand the availability for pollinator habitat resources in a management gradient from shade-grown coffee agroforestry to conventional farming systems that employ both organic and non-organic management practices. I examined the influence of farming and land-use practices on the availability and quality of habitats for social and solitary bee species through observations of …

Continuous Monitoring Reveals Multiple Controls On Ecosystem Metabolism In A Suburban Stream, Jake J. Beaulieu, Clay P. Arango, David A. Balz, William D. Shuster

Biology Faculty Scholarship

1. Primary production and respiration in streams, collectively referred to as stream ecosystem metabolism, are fundamental processes that determine trophic structure, biomass and nutrient cycling. Few studies have used high‐frequency measurements of gross primary production (GPP) and ecosystem respiration (ER) over extended periods to characterise the factors that control stream ecosystem metabolism at hourly, daily, seasonal and annual scales.

2. We measured ecosystem metabolism at 5‐min intervals for 23 months in Shepherd Creek, a small suburban stream in Cincinnati, Ohio (U.S.A.).

3. Daily GPP was best predicted by a model containing light and its synergistic interaction with water temperature. Water …

Ten Reasons To Take Peak Oil Seriously, Robert Brecha

Physics Faculty Publications

Forty years ago, the results of modeling, as presented in The Limits to Growth, reinvigorated a discussion about exponentially growing consumption of natural resources, ranging from metals to fossil fuels to atmospheric capacity, and how such consumption could not continue far into the future. Fifteen years earlier, M. King Hubbert had made the projection that petroleum production in the continental United States would likely reach a maximum around 1970, followed by a world production maximum a few decades later. The debate about “peak oil," as it has come to be called, is accompanied by some of the same vociferous …

Brief 7: Building An International Court For The Environment: A Conceptual Framework, Philip Riches, Stuart A. Bruce

Governance and Sustainability Issue Brief Series

This issue brief considers the role and nature of existing and potential international dispute resolution fora in relation to international environmental law. It addresses impediments at the international level, such as limited access to justice by non-state actors and the lack of technical and scientific capability. As a conceptual paper, it highlights two possible remedial options: an international environmental tribunal and an international environmental court.

Potential Water Quality Impacts Originating From Land Burial Of Cattle Carcasses, Qi Yuan, Daniel D. Snow, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

Among the conventional disposal methods for livestock mortalities, on‐farm burial is a preferred method, but the potential water quality impacts of animal carcass burial is not well understood. Typically, on‐farm burial pits are constructed without liners to prevent percolation of leachate into soil and groundwater. To date, no information is available on temporal trends for contaminants in leachate produced from livestock mortality pits. In our study, we examined the concentrations of conventional contaminants (electrical conductivity, COD, TOC, TKN, TP, and solids) as well as some antimicrobials and steroid hormones for a period of 20 months. High concentrations of conventional contaminants …

Tackling Change: Future-Proofing Water, Agriculture, And Food Security In An Era Of Climate Uncertainty, Peter G. Mccornick, Vladimir Smakhtin, Luna Bharati, Robyn Johnston, Matthew Mccartney, Fraser Sugden, Floriane Clement, Beverly Mcintyre

Daugherty Water for Food Global Institute: Faculty Publications

In 1950 the global population was just over 2.5 billion. Now, in 2013, it is around 7 billion. Although population growth is slowing, the world is projected to have around 9.6 billion inhabitants by 2050. Most of the population increase will be in developing countries where food is often scarce, and land and water are under pressure. To feed the global population in 2050 the world will have to produce more food without significantly expanding the area of cultivated land and, because of competition between a greater number of water users, with less freshwater. On top of land and water …

Evaluating The Roles Of Visual Openness And Edge Effects On Nest-Site Selection And Reproductive Success In Grassland Birds, Alexander C. Keyel, Allan M. Strong, Noah G. Perlut, J. Michael Reed

Environmental Studies Faculty Publications

In some species, habitat edges (ecotones) affect nest-site selection and nesting success. Openness, or how visually open a habitat is, has recently been shown to influence grassland bird density and may affect nest-site selection, possibly by reducing the risk of predation on adults, nests, or both. Because edge and openness are correlated, it is possible that effects of openness have been overlooked or inappropriately ascribed to edge effects. We tested the roles of edges and visual openness in nest-site selection and nesting success of two grassland passerines, the Bobolink (Dolichonyx oryzivorus) and Savannah Sparrow (Passerculus sandwichensis), …

Un-Redd And The Yasuní-Itt Initiative As Global Environmental Governance Mechanisms, Dominique De Wit

Bridges: A Journal of Student Research

The importance of reaching out to and including local stakeholders and local norms is becoming a factor within the formation and implementation of global environmental governance mechanisms. In recent years the Ishpingo-Tambococha-Tiputini (ITT) block of the Ecuadorian Yasuní National Park has caught widespread international attention due to its biological and cultural diversity, as well as its impact on carbon emissions at a time when climate change is a big concern for many. This article evaluates the contradictions and imperatives of two initiatives, the first being the Yasuní-ITT Initiative, formulated domestically on alternative non-extraction norms. The second is the United Nations …

Green Politics In China: Environmental Governance And State-Society Relations, Joy Y. Zhang, Michael S. Barr

Books

Based on interviews with members of grassroots organisations, media and government institutions, Green Politics in China is an in-depth account of the novel ways Chinese society is responding to its environmental crisis, using examples rarely captured in Western media or academia.

The struggle for clean air, low-carbon conspiracy theories, is transforming Chinese society, producing new forms of public fund raising and the encouraging the international tactics of grassroots NGOs. In doing so, they challenge static understandings of state-society relations in China, providing a crucial insight into the way in which China is changing internally and emerging as a powerful player …

Impact Of Climate Change On Human And Ecological Use Of Karst Groundwater Resources: A Case Study From The Southwestern Usa, George Veni

National Cave and Karst Management Symposium 2013

Climate change models for the arid southwestern USA predict increasing temperatures and declines in precipitation. These changes will have multiple adverse impacts on water and ecological resources and pose diverse challenges on their management. The San Solomon Spring system of west Texas discharges from the western edge of the karstic Edward-Trinity Plateau Aquifer. It consists of six springs in Jeff Davis and Reeves counties, is one of the largest spring groups in the state, and provides water for agricultural use and habitat to two federally listed endangered species and three species proposed for listing. It serves in this paper as …

Volatilization Of Benzene In A River, Eric Dunlop

Undergraduate Journal of Mathematical Modeling: One + Two

Benzene is a volatile organic compound: when it contaminates a river, some of the substance will evaporate as it flows through. We examine the volumetric flow rate to find how volatilization affects the concentration levels of benzene as the substance flows through several consecutive sections of a river, using a specific example to illustrate the general method.

Study Of Dieldrin In Coralville Reservoir, Jeremy Smith

Undergraduate Journal of Mathematical Modeling: One + Two

Using existing experimental data taken over a period of roughly 12 years that documents the concentrations of dieldrin levels in the environment and fatty tissue of the fish, we construct a model of the total dieldrin concentration decline. Comparisons between the experimental data and speculative data can be made using calculus and elements of statistics in order to better understand the movement of dieldrin in the reservoir. Because of the potentially harmful exposure effects of dieldrin to humans as well as the environment, it is important to be able to predict when stability has been restored to the ecosystem.

Degradable Plastics And Solid Waste Management Systems, David J. Tonjes, Krista L. Thyberg

Technology & Society Faculty Publications

Plastics, which are woven into the fabric of modern life, have consequential impacts on the environment. Many of these are associated with end-of-lifetime processes, and include chemical contamination of the environment and effects from litter. Plastics also complicate waste management processes, causing contamination in composting operations, and having poor recovery rates through recycling. Plastics that are not as biologically recalcitrant, that decompose when use is done, have been perceived as solutions to at least some of these problems. The first generation of degradable plastics did not meet marketing claims; some of the more recent formulations, partly as a consequence of …

Bioavailability Of Manufactured Nanomaterials In Terrestrial Ecosystems, Jonathan D. Judy

Theses and Dissertations--Plant and Soil Sciences

Manufactured nanomaterials (MNMs) from the rapidly increasing number of consumer products that contain MNMs are being discharged into waste streams. Increasing evidence suggests that several classes of MNMs may accumulate in sludge derived from wastewater treatment and ultimately in soil following land application as biosolids. Little research has been conducted to evaluate the impact of MNMs on terrestrial ecosystems, despite the fact that land application of biosolids from wastewater treatment will be a major pathway for the introduction of MNMs to the environment. To begin addressing this knowledge gap, we have conducted a series of experiments designed to test how …

Conservation Mooring Study, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

Most boaters who moor their vessels in Massachusetts waters have traditionally employed free swinging moorings that use heavy bottom chain. In important sensitive habitats such as eelgrass beds, these types of moorings often have negative impacts on the benthic habitat – from the circular movement of the chain around the anchor point, and/or from the anchor itself.

This document objectively describes the different characteristics of conventional moorings versus conservation moorings designed to minimize disruption to the benthic habitat. This report includes discussions on the following topics:

• Technologies available
• Ecological impacts
• Functional differences
• Economical differences
• Regulatory issues

These comparisons, along with …

United States Environmental Protection Agency: Publications

The State of California has mandated the preparation of a guidance document on the application of fecal source identification methods for recreational water quality management. California contains the fifth highest population of cattle in the United States, making the inclusion of cow-associated methods a logical choice. Because the performance of these methods has been shown to change based on geography and/or local animal feeding practices, laboratory comparisons are needed to determine which assays are best suited for implementation. We describe the performance characterization of two end-point PCR assays (CF128 and CF193) and five real-time quantitative PCR (qPCR) assays (Rum2Bac, BacR, …

Fumigation Of A Laboratory-Scale Hvac System With Hydrogen Peroxide For Decontamination Following A Biological Contamination Incident, K. M. Meyer, M. W. Calfee, J. P. Wood, L. Michelsen, B. Attwood, M. Clayton, A. Touati, R. Delafield

The Biology And Taxonomy Of Head And Body Lice— Implications For Louse-Borne Disease Prevention, Denise L. Bonilla, Lance A. Durden, Marina E. Eremeeva, Gregory A. Dasch

Environmental Health Sciences: Faculty Publications

Sucking lice (Phthiraptera: Anoplura) are obligate blood-feeding ectoparasites of placental mammals including humans. Worldwide, more than 550 species have been described and many are specific to a particular host species of mammal [1]. Three taxa uniquely parasitize humans: the head louse, body louse, and crab (pubic) louse. The body louse, in particular, has epidemiological importance because it is a vector of the causative agents of three important human diseases: epidemic typhus, trench fever, and louse-borne relapsing fever. Since the advent of antibiotics and more effective body louse control measures in the 1940s, these diseases have markedly diminished in incidence. However, …

Using Gis To Delineate Headwater Stream Origins In The Appalachian Coal-Belt Region Of Kentucky, Jonathan A. Villines

Theses and Dissertations--Biosystems and Agricultural Engineering

Human activity such as surface mining can have substantial impacts on the natural environment. Performing a Cumulative Hydrologic Impact Assessment (CHIA) of such impacts on surface water systems requires knowing the location and extent of these impacted streams. The Jurisdictional Determination (JD) of a stream’s protected status under the Clean Water Act (CWA) involves locating and classifying streams according to their flow regime: ephemeral, intermittent, or perennial. Due to their often remote locations and small size, taking a field inventory of headwater streams for surface mining permit applications or permit reviews is challenging. A means of estimating headwater stream location …

Acequias, Brigette Buynak, Jerold Widdison, Darcy S. Bushnell

Water Matters!

Acequias are community irrigation systems in the villages and pueblos of New Mexico. They have deep roots in two ancient traditions—Pueblo Indian and Spanish. The Pueblos collected and shared water for centuries before the arrival of Spanish colonists in 1598. The Spanish settlers brought technical knowledge and institutional frameworks for governing irrigation systems, which originated in the Moors’ seven-century occupation of Spain. Both traditions remain important to an understanding of New Mexico’s acequia heritage and the continuing relevance of these “water democracies.”Today, these traditions must meld with state law as the legislature has provided that acequias are “political subdivisions” or …

American Indian Water Rights, Michael Osborn, Darcy S. Bushnell

Water Matters!

Pueblos and tribal reservations are located within most of the larger stream systems in New Mexico. Each has claims to rights to use the water in its stream. In New Mexico, Indian rights are significant because of their early priority dates, because of the large amounts of water rights claimed, or both. In some instances, such claims have the potential to displace a significant number of junior water rights.

Common law theories or doctrines pertaining to Indians continue to be judicially refined and to evolve so that discussing the nature and extent of “Indian water rights” is a complex topic.

Groundwater, Darcy S. Bushnell, Diego Urbina

Water Matters!

Since the late nineteenth century, New Mexicans have been developing the state’s groundwater resources. From hand-dug wells to proposed wells that could penetrate to 12,000 feet, residents have sought sources to supplement and replace surface water. The state relies upon groundwater to supply almost 50 percent of its needs.

As the population grows and drought intensifies, groundwater sources are tapped with increasing urgency. Limited steps are being taken to preserve groundwater through conservation, groundwater recharge, and regulation.

State And Regional Water Planning, Brigette Buynak, Susan Kelly, Sarah Armstrong

Water Matters!

A statewide water planning effort was initiated by the New Mexico legislature in the 2003 session. The Interstate Stream Commission (ISC),in collaboration with the Office of the State Engineer (OSE) and the Water Trust Board, was tasked with preparing and implementing a comprehensive state water plan. Regional water planning had begun much earlier, prompted by a lawsuit that El Paso filed against New Mexico in 1983, El Paso v. Reynolds.

The State Water Plan Act of 2003 (Act) was intended to promote stewardship of the state’s water resources and to establish clear policies and strategies for management of the state’s …

Community Water Systems, Joanne Hilton, Susan Kelly, Sarah Armstrong

Water Matters!

Apart from the major cities along the Rio Grande corridor, much of New Mexico remains relatively rural. Recent studies estimate a 2013population of around 2,085,500 statewide. In the state fiscal year 2011,about 1,836,000 people, or 88 percent of New Mexico’s population obtain their water from community water systems. Approximately 284,000 people, or about14 percent of the population, receive their drinking water from community water systems serving fewer than 5,000 people. As of 2012, there are 1,148 public water systems that provide drinking water in New Mexico. Of these systems, 593are community water systems; of these, 546 serve fewer than 5,000 …
