    Notes: Abstract –  Movement and habitat use of river blackfish (Gadopsis marmoratus R.) was studied in a highly modified central Victorian stream (Birch Creek), Australia, using radio telemetry (N = 10) and mark–recapture (N = 113) between October 2001 to May 2002, and November to December 2002 respectively. Blackfish had a small home range of 10–26 m with strong affinity to a pool. However, small movements within a pool were common which resulted in relatively large cumulative movements. At a diel scale there were no significant differences in blackfish movement between day and night (Kruskal–Wallis test, P = 0.95). Six of seven blackfish translocated 40 m upstream or downstream of their original positions returned within 48 h, suggesting strong affinity not only to a pool, but also to a small region within a pool. Blackfish utilised slow flowing (0–20 cm s−1) and deep waters (40–60 cm). Blackfish were strongly associated with the instream cover habitats of undercut banks and boulders. Significant differences were recorded in instream cover and water velocity used by blackfish between day and night (Kruskal–Wallis test, P = 〈0.01). At night blackfish used open areas with high water velocities whereas during the day blackfish used complex undercut banks with low water velocities.

    Notes: Abstract. We hypothesized that fluoride partly acts by changing the levels of circulating calcium-regulating hormones and skeletal growth factors. The effects of oral fluoride on 24 female, Dutch-Belted, young adult rabbits were studied. The rabbits were divided into two study groups, one control and the other receiving about 16 mg fluoride/rabbit/day in their drinking water. After 6 months of fluoride dosing, all rabbits were euthanized and bone and blood samples were taken for analyses. Fluoride treatment increased serum and bone fluoride levels by over an order of magnitude (P 〈 0.001), but did not affect body weight or the following serum biochemical variables: urea, creatinine, phosphorus, total protein, albumin, bilirubin, SGOT, or total alkaline phosphatase. No skeletal fluorosis or osteomalacia was observed histologically, nor did fluoride affect serum PTH or Vitamin D metabolites (P 〉 0.4). BAP was increased 37% (P 〈 0.05) by fluoride; serum TRAP was increased 42% (P 〈 0.05); serum IGF-1 was increased 40% (P 〈 0.05). Fluoride increased the vertebral BV/TV by 35% (P 〈 0.05) and tibial ash weight by 10% (P 〈 0.05). However, the increases in bone mass and bone formation were not reflected in improved bone strength. Fluoride decreased bone strength by about 19% in the L5 vertebra (P 〈 0.01) and 25% in the femoral neck (P 〈 0.05). X-ray diffraction showed altered mineral crystal thickness in fluoride-treated bones (P 〈 0.001), and there was a negative association between crystal width and fracture stress of the femur (P 〈 0.02). In conclusion, fluoride's effects on bone mass and bone turnover were not mediated by PTH. IGF-1 was increased by fluoride and was associated with increased bone turnover, but was not correlated with bone formation markers. High-dose fluoride treatment did not improve, but decreased, bone strength in rabbits, even in the absence of impaired mineralization.

    Notes: Abstract ForX a set the expression Prt(X) denotes the composition monoid of all functionsf ⫅X ×X. Fork a positive integer the letterk denotes also the set of all nonnegative integers less thank. Whenk 〉 1 the expression rk denotes the connected injective element {〈i, i + 1〉∶i ε k − 1} in Prt (k). We show for every word w=w(x,y) in a two-letter alphabet that if the equation w(x, y)=rk has a solution 〈x, y〉=〈x,y) ε2Prt(k) then ¯w(x,y)=rk also has a solution in2Prt(k), where ¯w is the word obtained by spelling the wordw backwards. It is a consequence of this theorem that if for every finite setX and for everyf ε Prt(X) the equation w(x,y)=f has a solution in2Prt(X) then for every suchX andf the equation ¯w(x, y)=f has a solution in2Prt(X).

    Morphology and photosynthetic physiology of Grimmia antarctici from wet and dry habitats (1990)

    Notes: Summary Photosynthetic capacity, chlorophyll content and leaf and cell morphology were compared in Grimmia antarctici from wet and dry sites in the Bailey Peninsula SSSI, near Casey Station, East Antarctica. In wet sites G. antarctici grew as a turf with tall shoots of loosely packed long leaves: in very dry sites it formed small cushions with short shoots of small tightly packed leaves. Intermediate forms (large cushions) were also frequently observed in less extreme situations. Cell size and number were greater in drier sites. The chlorophyll content, chlorophyll a/b ratio and the light saturated photosynthetic and dark respiration rates at full turgor and under enhanced conditions of CO2 were the same. This rules out a direct effect of water stress on the integrity of the photosynthetic apparatus and implies that the cushion form is a product of direct effects of water availability on cell division and differentiation and CO2 assimilation under field conditions.

    Diagenesis of Neogene Delta-Front Patch Reefs: Alteration of Coastal, Siliciclastic-Influenced Carbonates from Humid Equatorial Regions (2012)
    Society for Sedimentary Geology (SEPM)
    Details
    Publication Date: 2012-12-11
    Description: :  This study offers insights into the diagenetic alteration of coastal carbonates that formed coevally with nearly continuous siliciclastic influx in a humid equatorial setting. A multi-disciplinary petrographic, cathodoluminescent, stable-isotope, trace-element and major-element investigation allowed characterization of diagenetic features, paragenetic sequencing, and an interpretation of diagenetic environments from Neogene patch reefs of the Samarinda region, Mahakam Delta, Borneo, SE Asia. Marine cements are absent from the patch reefs, with grain micritization the only marine diagenetic feature recognized. The predominant diagenetic feature within the patch reefs is pervasive neomorphic stabilization and cementation of aragonite reef components to calcite that pre-dates all compaction features. Meteoric aquifer flow derived from the adjacent landmass is inferred as the main parent diagenetic fluid, since 18 O V-PDB values of calcite cements of –3.6 to –11.7 are consistent with precipitation from SE Asian freshwater, and inconsistent with a wholly marine origin. Late-stage fracturing, cementation, and chemical compaction are relatively minor features and attest to a changing paleohydrologic and diagenetic environment. Evidence for a shallow to moderate burial diagenetic regime for these later features are maximum temperature of 53 °C and burial depths 〈 1000 m inferred from stable-isotope values of calcite and late dolomite cements, dolomite crystal fabrics, the onset depth of stylolite or dissolution-seam formation, and regional geothermal gradients. The humid tropical environment and "ever-wet" conditions on the island of Borneo together with rapid Cenozoic uplift likely led to paleoaquifer flow with fluids focused through adjacent deltaic units into the reef carbonates. In these coastal carbonates from the humid Samarinda region, continental groundwater flow has resulted in pervasive stabilization and calcitization, features rare in arid or temperate counterparts.

    Dominance rank and gene expression in macaques [Anthropology] (2012)
    National Academy of Sciences
    Details
    Publication Date: 2012-04-25
    Description: Variation in the social environment is a fundamental component of many vertebrate societies. In humans and other primates, adverse social environments often translate into lasting physiological costs. The biological mechanisms associated with these effects are therefore of great interest, both for understanding the evolutionary impacts of social behavior and in the context of human health. However, large gaps remain in our understanding of the mechanisms that mediate these effects at the molecular level. Here we addressed these questions by leveraging the power of an experimental system that consisted of 10 social groups of female macaques, in which each individual's social status (i.e., dominance rank) could be experimentally controlled. Using this paradigm, we show that dominance rank results in a widespread, yet plastic, imprint on gene regulation, such that peripheral blood mononuclear cell gene expression data alone predict social status with 80% accuracy. We investigated the mechanistic basis of these effects using cell type-specific gene expression profiling and glucocorticoid resistance assays, which together contributed to rank effects on gene expression levels for 694 (70%) of the 987 rank-related genes. We also explored the possible contribution of DNA methylation levels to these effects, and identified global associations between dominance rank and methylation profiles that suggest epigenetic flexibility in response to status-related behavioral cues. Together, these results illuminate the importance of the molecular response to social conditions, particularly in the immune system, and demonstrate a key role for gene regulation in linking the social environment to individual physiology.
