Latitudinal distribution and mitochondrial DNA (COI) variability of Stereotydeus spp. (Acari: Prostigmata) in Victoria Land and the central Transantarctic Mountains
No full textWe examined mitochondrial DNA (COI) variability and distribution of Stereotydeus spp. in Victoria Land and the Transantarctic Mountains, and constructed Neighbour Joining (NJ) and Maximum Likelihood (ML) phylogenetic trees using all publicly available COI sequences for the three Stereotydeus species present (S. belli, S. mollis and S. shoupi). We also included new COI sequences from Miers, Marshall and Garwood valleys in southern Victoria Land (78°S), as well as from the Darwin (79°S) and Beardmore Glacier (83°S) regions. Both NJ and ML methods produced trees which were similar in topology differing only in the placement of the single available S. belli sequence from Cape Hallett (72°S) and a S. mollis haplotype from Miers Valley. Pairwise sequence divergences among species ranged from 9.5–18.1%. NJ and ML grouped S. shoupi from the Beardmore Glacier region as sister to those from the Darwin with pairwise divergences of 8%. These individuals formed a monophyletic clade with high bootstrap support basal to S. mollis and S. belli. Based on these new data, we suggest that the distributional range of S. shoupi extends northward to Darwin Glacier and that a barrier to dispersal for Stereotydeus, and possibly other arthropods, exists immediately to the north of this area

Statistical method for determining No Effect Concentration (NEC)
No full textProgress Code: completedStatement: Statistical study only on existing datasets.<b>Purpose</b><br/>Showcase a new statistical method for determining no effect concentrations (NEC).This data record has been compiled for a statistical methods study, conducted by Abigael Proctor as part of her PhD research in 2018. The data in this record have been used to showcase a new statistical method for determining no effect concentration (NEC). The study uses the data in this record to compare NEC and LCx estimates for copper in four Antarctic marine invertebrate species. The data associated with this record are a subset of four existing larger datasets: <br/>1. amphipod: AAS_2933_Orchomenella_pinguides_Sensitivity_metals_Davis_2010-11<br/>2. copepod: AAS_4100_Toxicity_Copepods<br/>3. gastropod: AAS_2933_MetaToxicityMarine_JuvenileGastropods_Kingston2007<br/>4. ostracod: AAS_2933_MetalToxicityMarine_BrownOstracods_Kingston2007<br/><br/>Subset details are described in the excel file provided
Photosynthetic responses of three common mosses from continental Antarctica
No full textPredicting the effects of climate change on Antarctic terrestrial vegetation requires a better knowledge of the ecophysiology of common moss species. In this paper we provide a comprehensive matrix for photosynthesis and major environmental parameters for three dominant Antarctic moss species (Bryum subrotundifolium, B. pseudotriquetrum and Ceratodon purpureus). Using locations in southern Victoria Land, (Granite Harbour, 77°S) and northern Victoria Land (Cape Hallett, 72°S) we determined the responses of net photosynthesis and dark respiration to thallus water content, thallus temperature, photosynthetic photon flux densities and CO2 concentration over several summer seasons. The studies also included microclimate recordings at all sites where the research was carried out in field laboratories. Plant temperature was influenced predominantly by the water regime at the site with dry mosses being warmer. Optimal temperatures for net photosynthesis were 13.7°C, 12.0°C and 6.6°C for B. subrotundifolium, B. pseudotriquetrum and C. purpureus, respectively and fall within the known range for Antarctic mosses. Maximal net photosynthesis at 10°C ranked as B. subrotundifolium > B. pseudotriquetrum > C. purpureus. Net photosynthesis was strongly depressed at subzero temperatures but was substantial at 0°C. Net photosynthesis of the mosses was not saturated by light at optimal water content and thallus temperature. Response of net photosynthesis to increase in water content was as expected for mosses although B. subrotundifolium showed a large depression (60%) at the highest hydrations. Net photosynthesis of both B. subrotundifolium and B. pseudotriquetrum showed a large response to increase in CO2 concentration and this rose with increase in temperature; saturation was not reached for B. pseudotriquetrum at 20°C. There was a high level of variability for species at the same sites in different years and between different locations. This was substantial enough to make prediction of the effects of climate change very difficult at the moment
Agnotology
No full textRobert Proctor e Ian Bolin acuñaron el término agnotología para designar el estudio de la ignorancia. Este escrito propone superar la visión de la ignorancia como un vacío que puede ser llenado por el conocimiento e invita a pensar en las formas en que hoy se produce, en forma premeditada y estructural: por negligencia, miopía, secreto o supresión. El autor muestra que la creación deliberada de la ignorancia es una estrategia para engañar y sembrar dudas sobre los hechos observados y sobre el conocimiento científico, tomando como ejemplos el papel de los secretos comerciales, la actividad de las tabacaleras para negar la relación causal entre el consumo de cigarrillos y el cáncer y el papel del secreto militar. Por último analiza algunos casos en que la ignorancia es una expresión de valores morales, como la prohibición, en algunas universidades, de investigaciones cuyo único fin es el afán de lucro y, en algunas revistas científicas, de publicar trabajos financiados por ciertas fuentes, así como el rechazo de ciertas tecnologías por razones intelectuales y morales bien fundadas.Robert Proctor and Ian Bolin coined the term agnotology to designate the study of ignorance. This paper proposes to overcome the vision of ignorance as a void that can be filled by knowledge and invites us to think about the ways in which it is produced today, in a premeditated and structural way: through negligence, myopia, secrecy or suppression. The author shows that the deliberate creation of ignorance is a strategy to compromise and sow doubts about the observed facts and about scientific knowledge, taking as examples the role of trade secrets, the activity of tobacco companies to deny the causal relationship between the cigarette smoking and cancer and the role of military secret. Finally, some cases in ignorance is an expression of moral values, such as the prohibition, in some universities, of research whose sole purpose is the profit motive and, in some scientific journals, of publishing works financed by certain sources, as well as the rejection of certain technologies for well-founded intellectual and moral reasons

Vegetation of montane bogs in east-flowing catchments of northern New England, New South Wales
No full textThe floristics of the montane bogs in east-flowing catchments of northern New England, north-eastern New South Wales (lat 28° 47’–31° 25’ S; long 151° 50’–152° 30’ E), are described from 62 full floristic survey sites (20 x 20 m in area). Eight vegetation communities are based on flexible UPGMA analysis of cover-abundance scores of vascular plant taxa. Shrub species make up 26% of the flora and herb species 69%, with the remaining taxa trees, climbers or vines. Shrub species were of little diagnostic value, as a few common dominants were shared across most communities. The herbaceous layer was found to be of better circumscriptive value. Communities described (based on dominant herbaceous species) are: (1) Themeda australis – Gonocarpus micranthus, (2) Baumea articulata – Baloskion stenocoleum, (3) Lepidosperma limicola – Baloskion stenocoleum, (4) Baloskion fimbriatum – Lomandra longifolia, (5) Lepyrodia scariosa – Blandfordia grandiflora, (6) Lepidosperma gunnii – Lepidosperma scariosa, (7) Baloskion stenocoleum – Empodisma minus, (8) Lepidosperma limicola – Xyris operculata. The mean annual moisture index was found to account for 26% of the variation in species density. These montane bog systems are some of the richest in Australia, with a high number of rare and restricted taxa. They are vulnerable to both present landuse practices and future changes in climate, are restricted in area, and need further conservation efforts to ensure their long-term survival
