Adaptive radiation plays a fundamental role in our understanding of the evolutionary process. However, the concept has provoked strong and differing opinions concerning its definition and nature among researchers studying a wide diversity of systems. Here, we take a broad view of what constitutes an adaptive radiation, and seek to find commonalities among disparate examples, ranging from plants to invertebrate and vertebrate animals, and remote islands to lakes and continents, to better under…

Aberrant emotion processing is a hallmark of posttraumatic stress disorder (PTSD), with neurobiological models suggesting both heightened neural reactivity and diminished habituation to aversive stimuli. However, empirical work suggests that these response patterns may be specific to subsets of those with PTSD. This study investigates the unique contributions of PTSD symptom clusters (re-experiencing, avoidance and numbing, and hyperarousal) to neural reactivity and habituation to negative st…

This study examined the use of biochar to alleviate sulfide toxicity to methane producing archaea (MPA) and sulfate-reducing bacteria (SRB) during anaerobic treatment of sulfate-rich wastewater with concomitant sulfur recovery. At the sulfate concentration of 6000 mg SO/L, the dissolved sulfide (DS) of 131 mg S/L resulted in total volatile fatty acids concentration of 3500 mg/L as acetic acid (HAc) and the reactors were on the verge of failure. Biochar removed >98% of HS, 94% of DS, and 89% o…

Capsanthin, like other carotenoids, exhibits poor aqueous solubility, poor stability, and low/variable oral bioavailability that limit its utility as a nutraceutical. In this study, we describe the development of anhydrous nanoemulsion preconcentrate of capsanthin, which upon dilution with water, spontaneously forms nanoemulsion resulting in improved solubility of capsanthin without compromising its chemical stability and antioxidant activity. We chose Food and Drug Administration-approved in…

The rat lungworm () has emerged as an important human and animal health concern in Hawaii, US. Although the life cycle of the parasite requires both rat and gastropod hosts, other animals acting as paratenic hosts, such as frogs and centipedes, have been identified as sources of infection. We investigated the occurrence of rat lungworm infections in potential paratenic hosts in Hawaii to provide information on how they might be involved in transmission of angiostrongyliasis. We confirmed the …

Mycobacterium tuberculosis (Mtb) is a bacterial pathogen that causes a potentially serious infectious disease called tuberculosis (TB). Cyclohexapeptide wollamides A and B were recently isolated from Streptomyces nov. sp. (MST-115088) and subsequently reported to show excellent in vitro antituberculosis activity with minimum inhibitory concentration (MIC) of 1.56 μg/mL against Mtb (H37Rv) and favorable selectivity profile. This chapter describes the detailed synthesis of antitubercular wollam…

spp. are commensal yeasts that can cause cutaneous ailments such as dandruff and seborrheic dermatitis. We sought to develop a cost-effective, herbal formulation for the treatment of cutaneous ailments related to spp. Aqueous and ethanolic extracts of fenugreek ( L.) leaves exhibited activity against a clinical isolate and commercial strain of . The extracts were also found to be active against other pathogenic fungi such as and . Qualitative and quantitative phytochemical evaluation of aqueo…

Fungi are ubiquitous and often abundant components of virtually all ecosystems on Earth, serving a diversity of functions. While there is clear evidence that fungal-mediated processes can influence environmental conditions, and in turn select for specific fungi, it is less clear how fungi respond to environmental fluxes over relatively long time frames. Here we set out to examine changes in airborne fungi collected over the course of 13 y, which is the longest sampling time to date. Air filte…

The metabolisms of anaerobic ammonium oxidation (anammox) bacteria related to ammonia oxidation with nitrite reduction and autotrophic carbon fixation have been extensively observed. However, little is known about the specific metabolic pathways associated with oxygen detoxification and organic carbon utilization. To this end, we obtained high abundance of anammox species (∼50%) in a lab-scale continuous stirred-tank reactor (CSTR) at room temperature without strict anaerobic condition. The d…

Predicting how stream fishes may respond to habitat restoration efforts is difficult, in part because of an incomplete understanding of how basic biological parameters such as growth and ontogenetic habitat shifts interact with flow regime and riverscape ecology. We assessed age-specific Guadalupe Bass Micropterus treculii habitat associations at three different spatial scales in the South Llano River, a spring-fed stream on the Edwards Plateau of central Texas, and the influence of habitat a…
