The effects of power plant passage on zooplankton mortalities: Eight years of study at the Donald C. Cook nuclear plant

Zooplankton mortalities resulting from passage through the Donald C. Cook Nuclear Plant (southeastern Lake Michigan) were studied over an 8-year (1975-1982) period. The power plant operated at a low [Delta]T (Diaptomus spp, Eurytemora affinis and Limnocalanus macrurus) were most sensitive to plant passage, cyclopoid copepods least sensitive, while cladocerans (Daphnia spp, Eubosmina coregoni) were intermediate in sensitivity. There was no relationship between zooplankton mortalities and temperature ([Delta]T, discharge water temperature), suggesting that thermal stresses were not the major source of mortality. The single exception was September 1978 when discharge water temperatures exceeded 35[deg]C and there were large differences between intake and discharge water zooplankton mortalities (net mortality differences of 14-22% for the two units). Mechanical stresses appeared to be the major cause of zooplankton mortality. However, there was only a weak relationship between mortality as a result of plant passage and zooplankton size. Based on our long-term preoperational (1970-1974) and operational (1975-1982) ecological studies in the vicinity of the power plant, we hypothesize that fish predation, rather than power plant operation, probably was the major source of zooplankton mortality in inshore waters during much of the year.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26160/1/0000237.pd

British Cardiovascular Society Young Investigator Award 2019

The four finalists for the 2019 British Cardiovascular Society (BCS) Young Investigator Award (YIA) were selected from a competitive pool of young researchers. At the BCS meeting in Manchester last June, each finalist gave a 10min oral presentation, followed by questions from a panel of independent judges. All finalists were guests of the BCS at the Society’s Annual Dinner, and first prize was awarded to Donna Page and presented by Dr Simon Ray, BCS President. The details of the four YIA finalists and their academic training and interests can be seen below. We look forward to seeing new investigators and ideas at next year’s meeting and encourage all those training in cardiovascular research to submit their best research to this competition

First Evidence of Peat Domes in the Congo Basin using LiDAR from a fixed-wing drone

This work was funded by CongoPeat, a NERC Large Grant (NE/R016860/1) to S.L.L. and E.T.A.M. (UAV data collection, I.J.D. time), a NERC Open CASE Studentship to S.L.L., I.L. and G.D. and a Phillip Leverhulme Prize to S.L.L. (peat depths).The world’s most extensive tropical peatlands occur in the Cuvette Centrale depression in the Congo Basin, which stores 30.6 petagrams of carbon (95% CI, 6.3–46.8). Improving our understanding of the genesis, development and functioning of these under-studied peatlands requires knowledge of their topography and, in particular, whether the peat surface is domed, as this implies a rain-fed system. Here we use a laser altimeter mounted on an unmanned airborne vehicle (UAV) to measure peat surface elevation along two transects at the edges of a peatland, in the northern Republic of Congo, to centimetre accuracy and compare the results with an analysis of nearby satellite LiDAR data (ICESat and ICESat-2). The LiDAR elevations on both transects show an upward slope from the peatland edge, suggesting a surface elevation peak of around 1.8 m over ~20 km. While modest, this domed shape is consistent with the peatland being rainfed. In-situ peat depth measurements and our LiDAR results indicate that this peatland likely formed at least 10,000 years BP in a large shallow basin ~40 km wide and ~3 m deep.Publisher PDFPeer reviewe

Katie Mitchell: feminist director as pedagogue

An Actor Prepares relates the reciprocal dialogue between teacher–director and actor to offer a pedagogical enquiry that moves beyond methodology to focus on the learning exchange. In the first decades of the twentieth century teacher–directors, predominantly male, were responsible for developing theatrical pedagogies. In the twenty-first century, it is rare to focus on the director as pedagogue or attend to the complex learning exchange between director and actor. Furthermore, curriculums continue to be dominated by predominantly male lineages. Yet a focus on pedagogical approaches allows us to look behind methodologies, what an actor does, to consider how an actor learns. What might a gendered consideration of rehearsal practices reveal about the particular features of acting pedagogy? How do feminist interventions reconsider aspects of Stanislavski’s approach? I turn to the developed pedagogy of Katie Mitchell to examine her work as a form of écriture féminine which creates a post-Stanislavski schooling for actors. Applying a methodology for observing pedagogic practice in the rehearsal room that has been developed over four years of research I consider her approach, drawing upon two extended interviews, observations across four rehearsal processes and interviews with the actors involved. I reflect on her process through a gendered lens as an evolved form of method of physical action, which I re-orientate as a method of feminist action. The particular features of this pedagogy map Mitchell’s contribution to developing twenty-first century actor training from a feminist position

Evolutionary comparisons of chelonid alphaherpesvirus 5 (ChHV5) genomes from fibropapillomatosis-afflicted green (chelonia mydas), Ooive ridley (lepidochelys olivacea) and kemp’s ridley (lepidochelys kempii) sea turtles

peer-reviewedThe spreading global sea turtle fibropapillomatosis (FP) epizootic is threatening some of Earth’s ancient reptiles, adding to the plethora of threats faced by these keystone species. Understanding this neoplastic disease and its likely aetiological pathogen, chelonid alphaherpesvirus 5 (ChHV5), is crucial to understand how the disease impacts sea turtle populations and species and the future trajectory of disease incidence. We generated 20 ChHV5 genomes, from three sea turtle species, to better understand the viral variant diversity and gene evolution of this oncogenic virus. We revealed previously underappreciated genetic diversity within this virus (with an average of 2035 single nucleotide polymorphisms (SNPs), 1.54% of the ChHV5 genome) and identified genes under the strongest evolutionary pressure. Furthermore, we investigated the phylogeny of ChHV5 at both genome and gene level, confirming the propensity of the virus to be interspecific, with related variants able to infect multiple sea turtle species. Finally, we revealed unexpected intra-host diversity, with up to 0.15% of the viral genome varying between ChHV5 genomes isolated from different tumours concurrently arising within the same individual. These findings offer important insights into ChHV5 biology and provide genomic resources for this oncogenic viru

Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators

The human X and Y chromosomes evolved from an ordinary pair of autosomes, but millions of years ago genetic decay ravaged the Y chromosome, and only three per cent of its ancestral genes survived. We reconstructed the evolution of the Y chromosome across eight mammals to identify biases in gene content and the selective pressures that preserved the surviving ancestral genes. Our findings indicate that survival was nonrandom, and in two cases, convergent across placental and marsupial mammals. We conclude that the gene content of the Y chromosome became specialized through selection to maintain the ancestral dosage of homologous X-Y gene pairs that function as broadly expressed regulators of transcription, translation and protein stability. We propose that beyond its roles in testis determination and spermatogenesis, the Y chromosome is essential for male viability, and has unappreciated roles in Turner (tm) s syndrome and in phenotypic differences between the sexes in health and disease
