The catalytic reduction of emissions from a natural gas fueled spark ignited engine

Green, Michael Nathan (University of Alabama Libraries, 1995)

Activity in converting gasoline engines to operate on natural gas has increased in recent years due to the passage of The Clean Air Act of 1990 and The National Energy Policy in 1992 (EP ACT). Both policies require ...

Coastal salt marshes are highly sensitive wetland ecosystems that can sustain long-term impacts from anthropogenic events such as oil spills. In this study, we examined the microbial communities of a Gulf of Mexico coastal ...
Rediscovery of Leptoxis compacta (Anthony, 1854) (Gastropoda: Cerithioidea: Pleuroceridae)

Whelan, Nathan V.; Johnson, Paul D.; Harris, Phil M. (PLOS, 2012)

The Mobile River Basin is a hotspot of molluscan endemism, but anthropogenic activities have caused at least 47 molluscan extinctions, 37 of which were gastropods, in the last century. Nine of these suspected extinctions ...
Lactate-starved neurons in ALS

Martinez, Bryan A. (Company of Biologists, 2012)
Homeotic functions of the Teashirt transcription factor during adult Drosophila development

Wang, Wei; Tindell, Neil; Yan, Shun; Yoder, John H. (Company of Biologists, 2013)

During Drosophila development region-specific regulation of target genes by Hox proteins is modulated by genetic interactions with various cofactors and genetic collaborators. During embryogenesis one such modulator of Hox ...
Diurnal patterns of gas-exchange and metabolic pools in tundra plants during three phases of the arctic growing season

Patankar, Rajit; Mortazavi, Behzad; Oberbauer, Steven F.; Starr, Gregory (Wiley, 2013)

Arctic tundra plant communities are subject to a short growing season that is the primary period in which carbon is sequestered for growth and survival. This period is often characterized by 24-h photoperiods for several ...
Characterization of Amoeboaphelidium protococcarum, an Algal Parasite New to the Cryptomycota Isolated from an Outdoor Algal Pond Used for the Production of Biofuel

Letcher, Peter M.; Lopez, Salvador; Schmieder, Robert; Lee, Philip A.; Behnke, Craig; Powell, Martha J.; McBride, Robert C. (PLOS, 2013)

Mass culture of algae for the production of biofuels is a developing technology designed to offset the depletion of fossil fuel reserves. However, large scale culture of algae in open ponds can be challenging because of ...
The Plastid Genome of the Red Macroalga Grateloupia taiwanensis (Halymeniaceae)

DePriest, Michael S.; Bhattacharya, Debashish; Lopez-Bautista, Juan M. (PLOS, 2013)

The complete plastid genome sequence of the red macroalga Grateloupia taiwanensis S.-M. Lin & H.-Y. Liang (Halymeniaceae, Rhodophyta) is presented here. Comprising 191,270 bp, the circular DNA contains 233 protein-coding ...
Intraspecific phenotypic variation in a fish predator affects multitrophic lake metacommunity structure

Howeth, Jennifer G.; Weis, Jerome J.; Brodersen, Jakob; Hatton, Elizabeth C.; Post, David M. (Wiley, 2013)

Contemporary insights from evolutionary ecology suggest that population divergence in ecologically important traits within predators can generate diversifying ecological selection on local community structure. Many studies ...
TorsinA rescues ER-associated stress and locomotive defects in C. elegans models of ALS

Thompson, Michelle L.; Chen, Pan; Yan, Xiaohui; Kim, Hanna; Borom, Akeem R.; Roberts, Nathan B.; Caldwell, Kim A.; Caldwell, Guy A. (Company of Biologists, 2014)

Molecular mechanisms underlying neurodegenerative diseases converge at the interface of pathways impacting cellular stress, protein homeostasis and aging. Targeting the intrinsic capacities of neuroprotective proteins to ...
Microbial Community Responses to Organophosphate Substrate Additions in Contaminated Subsurface Sediments

Martinez, Robert J.; Wu, Cindy H.; Beazley, Melanie J.; Andersen, Gary L.; Conrad, Mark E.; Hazen, Terry C.; Taillefert, Martial; Sobecky, Patricia A. (PLOS, 2014)

Background: Radionuclide-and heavy metal-contaminated subsurface sediments remain a legacy of Cold War nuclear weapons research and recent nuclear power plant failures. Within such contaminated sediments, remediation ...
Unexpected Rarity of the Pathogen Batrachochytrium dendrobatidis in Appalachian Plethodon Salamanders: 1957-2011

Muletz, Carly; Caruso, Nicholas M.; Fleischer, Robert C.; McDiarmid, Roy W.; Lips, Karen R. (PLOS, 2014)

Widespread population declines in terrestrial Plethodon salamanders occurred by the 1980s throughout the Appalachian Mountains, the center of global salamander diversity, with no evident recovery. We tested the hypothesis ...
USBombus, a database of contemporary survey data for North American Bumble Bees (Hymenoptera, Apidae, Bombus) distributed in the United States

Koch, Jonathan B.; Lozier, Jeffrey; Strange, James P.; Ikerd, Harold; Griswold, Terry; Cordes, Nils; Solter, Leellen; Stewart, Isaac; Cameron, Sydney A. (Pensoft, 2015)

Background Bumble bees (Hymenoptera: Apidae, Bombus) are pollinators of wild and economically important flowering plants. However, at least four bumble bee species have declined significantly in population abundance and ...
How integrated are behavioral and endocrine stress response traits? A repeated measures approach to testing the stress-coping style model

Boulton, Kay; Couto, Elsa; Grimmer, Andrew J.; Earley, Ryan L.; Canario, Adelino V. M.; Wilson, Alastair J.; Walling, Craig A. (Wiley, 2015)

It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) and that these may represent opposite ends of a continuously varying reactive-proactive ...
Drought-induced changes in flow regimes lead to long-term losses in mussel-provided ecosystem services

Vaughn, Caryn C.; Atkinson, Carla L.; Julian, Jason P. (Wiley, 2015)

Extreme hydro-meteorological events such as droughts are becoming more frequent, intense, and persistent. This is particularly true in the south central USA, where rapidly growing urban areas are running out of water and ...
