The lionfish, Pterois volitans (Linnaeus) and miles (Bennett), invasion of the Western Atlantic Ocean, Caribbean Sea Gulf Mexico has potential to alter aquatic communities represents a legitimate ecological concern. Several local removal programs have been initiated control this invasion, but it is not known whether efforts can substantially reduce lionfish numbers ameliorate these concerns. We used an age-structured population model evaluate efficacy identified critical data gaps for future...
Mercury is a global contaminant, which may be microbially transformed into methylmercury (MeHg), bioaccumulates. This results in potentially toxic body burdens high trophic level organisms aquatic ecosystems and maternal transfer to offspring. We previously demonstrated effects on developing fish including hyperactivity, altered time-to-hatch, reduced survival, dysregulation of the dopaminergic system. A link between gut microbiota central nervous system function teleosts has been...
The physiology of ticks supports a diverse community non-pathogenic and pathogenic organisms. This study aims to initially characterize the microbial present within colony-reared Amblyomma americanum using PCR variable region 5 16S rRNA gene followed by semiconductor sequencing classification sequence data Ribosomal Database Project MG-RAST analysis tools. Comparison amplicon library datasets revealed changes in microbiomes newly engorged nymphs, newly-molted adults, aged as well exposed...
Phenylketonuria (PKU) is a genetic disease characterized by the inability to convert dietary phenylalanine tyrosine hydroxylase. Given importance of gut microbes in digestion, genetically engineered microbe could potentially degrade some ingested from diet prior absorption. To test this, lyase gene Anabaena variabilis (AvPAL) was codon-optimized and cloned into shuttle vector for expression Lactobacillus reuteri 100-23C (pHENOMMenal). Functional AvPAL determined vitro, subsequently tested...
Ixodes scapularis, the blacklegged deer tick, is principal vector of Lyme disease in North America. Environmental factors are known to influence regional and seasonal incidence possibly endemicity northeastern upper mid-western regions United States. With a goal understand impact environmental temperature on microbial communities within we investigated bacterial microbiome colony-reared I. scapularis ticks statically incubated at different temperatures (4, 20, 30, 37°C) constant humidity...
The blacklegged tick, Ixodes scapularis, is the primary vector of Lyme disease spirochete Borrelia burgdorferi in North America. Though tick found across eastern United States, endemic to northeast and upper midwest rare or absent southern portion vector's range. In an effort better understand microbiome from diverse geographic climatic regions, we analysed bacterial community 115 I. scapularis adults collected vegetation Texas Massachusetts, representing extreme ends range, by massively...
Abstract Studies have demonstrated that environmental, host genetic, and socioeconomic factors influence the breast cancer prevalence landscape with a far-reaching on racial disparity to subtypes of cancer. To understand whether tissue harbors race-specific microbiota, we performed 16S rRNA gene-based sequencing retrospective tumor matched normal adjacent (NAT) samples collected from Black non-Hispanic (BNH) White (WNH) women. Analysis Triple Negative Breast (TNBC) Positive Cancer (TPBC)...
Summary Conditions were developed for the reproducible production, isolation and characterization of a novel microbial extracellular polysaccharide believed to be involved in transient viscous bulking at an industrial wastewater treatment plant. The exopolysaccharide was extracted from cell‐free culture supernatants Thauera sp. strain MZ1T grown on minimal medium with succinate. purified polymer found approximately 260 kDa size by gel‐permeation chromatography. GC–MS analysis alditol acetate...
We used an equilibrium yield model to simulate the effect of reducing exploitation on and average weight white crappies Pomoxis annularis, based empirical growth data various levels conditional natural mortality. Modeling indicated that would likely increase as fish increased mortality decreased; however, not substantially affect when exceeded 30–40%, regardless growth. For instance, a 250-mm minimum length limit provided higher than 200-mm only if was above less 30–40%. Average harvested...
Stochastic fluctuations (or "noise") in the single-cell populations of molecular species are shaped by structure and biokinetic rates underlying gene circuit. The noise is summarized its autocorrelation function. In this article, we introduce regulatory vector as a generalized framework for making inferences concerning circuit from Although most previous studies have focused primarily on magnitude component (given zero-lag function), our approach also considers correlation component, which...
Summary The performance of species richness estimators can be highly variable. Evaluating the accuracy and precision different for assemblages is common in ecological literature, but estimator rarely measured terms research goals such as detecting patterns diversity. We evaluated efficacy nonparametric to detect changes (i.e. type‐I type‐ II error rates) using two experimental designs: a block design trend analysis. also across variety species‐abundance distributions, number sample sizes....
Abstract To describe the presence and distribution of tickborne bacteria their vectors in Texas, USA, we screened ticks collected from humans during 2008–2014 for Rickettsia, Borrelia, Ehrlichia spp. Thirteen tick species were identified, 23% carried bacterial DNA at least 1 3 genera tested.
Phenylketonuria (PKU) is an inborn error of phenylalanine metabolism primarily treated through a phenylalanine-restrictive diet that frequently supplemented with amino acid formula to maintain proper nutrition. Little known the effects these dietary interventions on gut microbiome PKU patients, particularly in adults. In this study, we sequenced V4 region 16S rRNA gene from stool samples collected adults (n = 11) and non-PKU controls 21). Gut bacterial communities were characterized...
We investigated the macrohabitat use, microhabitat and food habits of shoal bass Micropterus cataractae largemouth M. salmoides in upper Chipola River, Florida. electrofished two macrohabitats (pools shoals) during summer (May–August) fall (September–December) 1999 2000. The ratio to differed among macrohabitats, being highest shoals lowest pools. Age-0 adult (age-1 older) were collected areas higher-than-average percentages rocky substrate both associated with reduced current velocity those...
