Implications Of Energetic Neutral Atoms Observed With Ibex-Lo For The Pressure Balance In The Heliosphere, André Galli, Peter Wurz, Nathan A. Schwadron, Eberhard Möbius, Stephen A. Fuselier, Justyna M. Sokół, Maciej Bzowski, Paweł Swaczyna, Kostas Dialynas, David J. Mccomas

Faculty Publications

Energetic Neutral Atoms (ENAs) from the heliosphere are a unique means to remotely image the boundary regions of our heliosphere. NASA's Interstellar Boundary Explorer (IBEX) has been very successful in measuring these ENAs since 2008 at energies from tens of eV to 6 keV.The ENA low energy range from tens of eV to solar wind energy (roughly 1 keV) has been sampled throughout an entire solar cycle with the IBEX-Lo ENA imager. This enables us to study the physical implications for the structure of the heliosphere and for the parent proton populations in the heliosheath and other plasma regions that …

The Climate Impact Of Tropical Peatland Degradation, René Dommain, Steve Frolking, Aurich Jeltsch-Thömmes, Fortunat Joos, John Couwenberg, Paul Glaser, Alexander Cobb, Charles Harvey

Faculty Publications

Southeast Asia is a global hotspot of peatland degradation and related greenhouse gas emissions. Anthropogenic impacts, mainly associated with agricultural conversion, shift Southeast Asian peatlands from carbon sinks to significant carbon sources. Here we first describe the impacts of anthropogenic drainage on landscape-scale carbon dynamics of individual peatlands and then use an impulse‐response model of radiative forcing to quantify the climate impacts of peat-carbon losses. Whereas water-table elevation (i.e. drainage depth) determines the magnitude of CO2 emissions at the site-scale, the geometric arrangement of artificial drainage networks determines carbon losses on the landscape-scale. Among all peatland greenhouse gas fluxes, the …

A New Synthesis Of Arctic-Boreal Carbon Fluxes For Improved Carbon Budget Estimates, Anna Virkkala, Isabel Wargowsky, Judith Vogt, Mckenzie Kuhn, Susan Natali, Brendan Rogers, Mathias Goeckede, Kyle Arndt, Jennifer Watts, Tiffany Windholz, Simran Madaan

Faculty Publications

The Arctic-boreal zone and its permafrost regions have historically been sparsely measured for carbon dioxide and methane fluxes. This data sparsity has created significant uncertainties in Arctic-boreal carbon budget estimates. However, over the past decade, the availability of Arctic-boreal carbon flux data has increased substantially. Yet, it remains scattered across different repositories, papers, and unpublished sources, making it hard to estimate more accurate Arctic-boreal carbon budgets. To address this research gap, we have compiled a database of Arctic-boreal carbon fluxes (ABCFlux v2) from flux repositories, literature, and site principal investigators, which will be openly distributed. The database includes carbon dioxide …

From "Open Ocean" To "Exposed Aquaculture": Why And How We Are Changing The Standard Terminology Describing "Offshore Aquaculture", Tyler Sclodnick, Michael Chambers, Barry Antonio Costa-Pierce, Tobias Dewhurst, Nils Goseberg, Kevin Gerald Heasman, Wolf Isbert, Gesche Krause, Daniel Wieczorek, Till Markus, Bela H. Buck

Faculty Publications

The term “offshore” with regards to aquaculture has hitherto encompassed various perspectives, including technology, geographic location, legal jurisdiction, and more. To resolve the ambiguity in this term and understand its implications for current and future aquaculture development, “offshore” should be resolved into two separate metrics: distance from shore and energy exposure. The United Nations Convention on the Law of the Sea (UNCLOS) distinguishes between internal waters, territorial sea, contiguous zone, exclusive economic zone (EEZ), and the high seas, but currently has no precise definition for “offshore” in its provisions, and therefore no applicable laws pertaining to “offshore” aquaculture. Regulating a …

Contrasting Responses Of Commercially Important Northwest Atlantic Bivalve Species To Ocean Acidification And Temperature Conditions, Teagan Mcmahon, Diana Thatcher, Branwen Williams, Alan Wanamaker, Brittany Jellison, Heidi Franklin, Katherine Guay, Nina M. Whitney, Joseph A. Stewart, Michèle Lavigne

Faculty Publications

Modern calcifying marine organisms face numerous environmental stressors, including overfishing, deoxygenation, increasing ocean temperatures, and ocean acidification (OA). Coastal marine settings are predicted to become warmer and more acidic in coming decades, heightening the risks of extreme events such as marine heat waves. Given these threats, it is important to understand the vulnerabilities of marine organisms that construct their shells from calcium carbonate, which are particularly susceptible to warming and decreasing pH levels. To investigate the response of four commercially relevant bivalve species to OA and differing temperatures, juvenile Mercenaria mercenaria (hard shell clams), juvenile Mya arenaria (soft shell clams), …

Insects All Around Us: A Four-Session Bug Club Lesson Plan For Grades 3-5 Covering The Biology And Importance Of Insects In Nebraska, Carolyn Almonte

Honors Program: Senior Projects (Public)

Insects are often overlooked in science curricula when talking about conservation due to the surrounding fear and disgust regarding insects. This disgust not only permeates the mindsets of students, but also teachers, which leads to a hesitance to incorporate an insect-based curriculum or club into a lesson. In response to this, I have created a four-session club curriculum that can be used across four two hour long sessions spread out across four weeks. The goals of this club are: to explain the key traits of insects and arthropods, differentiating the two groups; to explain and define the basic stages of …

Finite Sum Of Integral Operators From The Fractional Cauchy Spaces To Bloch-Type And Zygmund-Type Spaces, Rita A. Hibschweiler, Ajay K. Sharma

Faculty Publications

The family of fractional Cauchy transforms, defined on the open unit disc in the complex plane, is of classical and modern interest. Membership of an analytic function in the family is determined by the requirement that the function can be expressed as an integral of a certain kernel against a complex Borel measure on the disc. Such an integral representation imposes a growth condition on the function and its derivatives. This exposes a connection between the families of Cauchy transforms and familiar spaces of analytic functions, such as the Bloch spaces and the Zygmund space. The notion of a composition …

Latticed Stinkhorn, Emilee G. Seigworth

PANDION: The Osprey Journal of Research and Ideas

Artist Statement

Latticed Stinkhorn is a watercolor piece originally created for the special gallery of the 2023 Scientific Illustration course at the University of North Florida. It was inspired by my enduring fascination with the world of fungi, particularly specimens of the family Phallaceae. This watercolor piece offers a simple perspective of Clathrus ruber, a species commonly referred to as Latticed Stinkhorn. Like many members of the family, the reproductive fruiting body first surfaces encased in a cream-colored soft shell with a texture comparable to a leathery reptile egg. As the body ages, the initial shell disintegrates to reveal a …

Footprint Tools Tiptoeing Towards Nitrogen Sustainability, James N. Galloway, Elizabeth A. Castner, Elizabeth S M Dukes, Jessica Fox, Allison M. Leach

Faculty Publications

As we face multiple environmental crises (e.g. climate change, nutrient pollution, freshwater scarcity), there is often a disconnect between an entity’s activities and the pollution resulting from that activity. Footprint tools help address this disconnect. They are effective in educating people, institutions and communities on how their resource use results in environmental pollution and what we can do to moderate that pollution. These tools connect an entity’s activities with the associated pollution. Footprint tools are also constantly evolving. As we better understand how to best estimate emissions—especially from sources further removed like those from the supply chain—the guidance and methods …
