This article highlights the important role abscisic acid plays in the acclimation of plants to a combination of two different abiotic stresses.

In this article, freshwater macroinvertebrate diversity associated with lakes and ponds along the altitudinal gradient of a Magellanic sub-Antarctic watershed are assessed. A monotonic decline in species richness was observed with increasing elevation, with simpler and more even community composition at higher altitude. This pattern differs from the mid-peak trend found in streams of the same watershed. Functional feeding group structure also diminished with increasing elevation.

Presentation for the 2007 University Scholars Day at the University of North Texas. This presentation discusses research on characterizing the changes in tissue morphology occurring in the emu ductus arteriosus during hatching and what role apoptosis plays during the process of the ductus closure.

Editorial on the research topic Regulation of and by the Plant Cell Wall.

Article describes study which aimed to gain resolution in assessing the energetic demand associated with acid-base regulation by examining ion movement and O2 consumption rates of isolated intestinal tissue from Gulf toadfish acclimated to control or 1900 μatm CO2 (projected for year 2300).

In this article, a theoretical model of social empathic emotion is derived based on the principles of survival by extending the maximization of self-gains to include others as an extended-self. This extended-self model of optimization for survival provides the computational mechanisms in the optimization process to maximize self-gains without minimizing the gains (or maximizing losses) for the other individuals. Thus, it can resolve conflicts in a competitive environment, and change the social dynamics into a cooperative interaction instead.

This paper discusses a research study on independence and maneuverability related to regular exercise among non-institutionalized elderly adults.

This article contains the evaluation of temporal and geographic patterns of exposure to these four vector-borne diseases in Wisconsin as the Gray Wolf population expanded between 1985 and 2011.

Poster presentation for the 2007 University Scholars Day at the University of North Texas discussing research on hereditary factors in the development of myopia.

Article hypothesizing that lipoxygenase (LOX) participated in the metabolism of PU-NAEs through the formation of NAE-oxylipins. The data suggests that Arabidopsis LOXs indeed compete with FAAH to metabolize PU-NAEs during seedling establishment. Identification of endogenous amide-conjugated oxylipins suggests potential significance of these metabolites in vivo, and FAAH mutants may offer opportunities to address this in the future.

This article reports on the first analysis of urushiols in poison ivy stems by matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI).

Authors of the article propose that thyroid hormones play an important role in regulating development of endothermy during the nestling period in altricial birds. Their data suggests plasma thyroid hormone levels play an active role in the systemic development of endothermic capacity and the development of ventilatory control.

Article explores the ‘membrane pacemaker’ hypothesis which proposes a biochemical explanation for among-species variation in resting metabolism, based on the positive correlation between membrane docosahexaenoic acid (DHA) and metabolic rate. The authors tested this hypothesis using a novel model, altricial red-winged blackbird nestlings, predicting that the proportion of DHA in muscle and liver membranes should increase with the increasing metabolic rate of the nestling as it develops endothermy. In support of the membrane pacemaker hypothesis, DHA proportions increased in membranes from pectoralis muscle, muscle mitochondria and liver during post-hatch development. By contrast, elevated dietary DHA had no effect on resting metabolic rate, despite causing significant changes to membrane lipid composition.

Paper discusses metabolomics studies that link changes in primary or specialized metabolism to the defense responses of plants against bacterial, fungal, nematode, and viral pathogens.

Patent relating to creating transgenic plants.

Presentation for the 2007 University Scholars Day at the University of North Texas discussing research on respiratory and cardiovascular responses in internally pipped chicken embryos.

Article reveals that plants can integrate different local and systemic signals generated during conditions of stress combination. Furthermore, results show that the specific part at which plants sense the two co-occurring stresses makes a significant difference in how fast and efficient they acclimate.

Keynote address for the 2007 University Scholars Day delivered by Dr. Edward Dzialowski, This keynote speaker discusses the development of respiratory and cardiovascular systems using avian models.
