The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen 2018 Virginia Institute of Marine Science

The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen

Articles

Although both local processes (photosynthesis, respiration, grazing, and settling), and transport processes (advective transport and diffusive transport) significantly affect local phytoplankton dynamics, it is difficult to separate their contributions and to investigate the relative importance of each process to the local variability of phytoplankton biomass over different timescales. A method of using the transport rate is introduced to quantify the contribution of transport processes. By combining the time-varying transport rate and high-frequency observed chlorophyll a data, we can explicitly examine the impact of local and transport processes on phytoplankton biomass over a range of timescales from hourly to annually. For ...

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon 2018 The University of San Francisco

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon

Master's Theses

This thesis analyzes the international discourse of greenhouse gas emissions in relation to livestock production. Specific government ministries, research institutes, and multilateral organizations are framing a new strategy to mitigate emissions by using emissions intensity metrics. Emissions intensity is a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence of this metric in international discourse and the implications this shift has on the livestock sector globally. Ultimately ...


Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren 2018 Utah State University

Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren

All Graduate Theses and Dissertations

It is hypothesized that individuals make reproductive decisions based on current assessments of their physiological condition and environmental conditions. For female lesser scaup (Aythya affinis), breeding occurs after an energetically costly spring migration. Increasing fat reserves (i.e., ‘body condition’) prior to breeding allows a female to produce a larger clutch of eggs, but time spent gaining body condition is costly in terms of time allowed to raise ducklings before freezing conditions in the fall. In Chapter 2 I explored rate of pre-breeding body condition gain in female lesser scaup, and how that rate influenced clutch size. Spring phenology, measured ...

Highlights

• Everyday risk associated with inadequate basic infrastructure and poverty make even small natural hazards impactful in African cities.

• Enhanced development opportunity is the best for of risk reduction.

• Integrating risk reduction into development is constrained by donor priorities, fragmented city governance and data and monitoring gaps.

• Integrating risk reduction into development is enabled through community networks collaborating with city authorities, locally accountable leadership and improved risk data and forecasting.

Featured Art: Gaia With Dog And Inside Out, Carty Bledsoe

Journal of Sustainability Studies

The pressing need to take account of the wounded state of all living systems is pivotal in my work, plus a focus on the interior life of people living in a fractured world, disconnected from Earth’s cycles. I like to push space around by juxtaposing colors, playing the second dimension off the third. George Tooker, Max Beckman, and Giotto were early influences. I graduated from the Boston Museum School in 1990 with a focus on Drawing.

Operationalizing Sustainability, Robert Sroufe Ph.D. 2018 Duquesne University

Operationalizing Sustainability, Robert Sroufe Ph.D.

Journal of Sustainability Studies

Within this “how to” practices-based study is a generalizable framework of engagement and collaborative learning to operationalize sustainability for any organization. Purposefully cultivating the application of cross-disciplinary engagement, a phased approach is proposed to understanding complex, real-world sustainability challenges while making them material to an organization. Practical value for managers and future change agents includes a systematic approach, creative solutions, and feasible recommendations for new value propositions. Contributions of operationalizing sustainability include, but are not limited to: a structured approach to building a shared understanding of the sustainability paradigm; benchmarking; brainstorming; and prioritizing best-practice options. Pedagogical value for business students ...


Sustainability Of Education: An Ecopedagogical Approach, Gary Padgett 2018 University of North Alabama

Sustainability Of Education: An Ecopedagogical Approach, Gary Padgett

Journal of Sustainability Studies

This article is a call to action and further research. It also suggests that it is important to move from education about sustainability to the sustainability of education. In the tradition of Freire and Giroux, this article examines the commodification of education stakeholders and the impact this has on education. This article also explores how critical theory and ecopedagogy can change how the conversation is occurring within the field of education.


Economics And Sustainability, J. Doug Barrett Ph.D. 2018 University of North Alabama

Economics And Sustainability, J. Doug Barrett Ph.D.

Journal of Sustainability Studies

Economics exists as a discipline that governs one of the three pillars (with society and the environment) of sustainability. Traditional economic analysis has addressed some issues within the relatively new field of sustainability. The subfield of sustainability economics offers a normative approach to applying the tools of economics to sustainability problems. Systems theory offers further opportunities in this regard. The current work reviews some relevant work within the literature of sustainability economics and other applicable sources with a focus on the future of economics in sustainability research and applications.

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D. 2018 Molloy College

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D.

Dr. John T. Tanacredi

A periodic pause to intensely observe a singularly unique ecosystem sharpens one's awareness of this diverse world of ours, especially, as the author notes, if one observes a transitional ecosystem whose ecological treasures are hidden or maybe obscured by a tidal sediment's resemblance to a large, rotten cheese! "It smells, is slimy and sticky, is punched with holes and crowded with various worms." Sounds good to me! Reise's "pause" encompasses 10 years in which he investigated the Wadden Sea mudflats near the border between West Germany and Denmark. He uses this site to discuss the biotic and ...


Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz 2018 Molloy College

Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz

Dr. John T. Tanacredi

Growth rates, body weight, density and biomass of ribbed mussels, Geukensia demissa (Dillwyn), were determined at Spartina alterniflora marsh-flat sites in Jamaica Bay, New York (Lower Hudson Estuary). Cumulative growth and annual growth increments varied but rates were lower at sites within the central bay relative to peripheral sites. Local variability both in size at Ring-1 and size-specific annual growth rates probably account for the variability in cumulative length. No pattersn were noted in frequency distributions of shell size but congruence in age structure was observed among neighboring sites in some areas of the bay. Mussel densities were greater within ...

The Coastal Monitor: Vol. 1, No. 2, John Tanacredi Ph.D.

Dr. John T. Tanacredi

At a recent event a colleague asked me, “So what do you do at CERCOM?” My immediate response was the “M” word fundamentally! After 45 years involved in environmental sciences, monitoring remains the most important and critical aspect of not only any field station in support of the academics conducted, but the seminal responsibility to be able, as a scientist, to reveal trends in the massive volume of data collected through routine monitoring exercises. It is extremely rare for a single data point, or even a single season of data, no matter how accurate the individual data point is, to ...
