  • Analysis of ontogenetic growth trends in two marine Antarctic bivalves Yoldia eightsi and Laternula elliptica: Implications for sclerochronology 

    Román-González, A; Scourse, JD; Butler, PG; Reynolds, DJ; Richardson, CA; Peck, LS; Brey, T; Hall, IR (Elsevier, 2016-05-11)
    There is an increasing use of marine species as palaeoclimate recorders for the marine realm. These archives provide novel baseline records of past oceanographic variability in regions devoid of instrumental observations. ...

    Jones, MI; Parker, JK (Elsevier, 2017-05-12)

    Background: Shiga toxin producing Escherichia coli O157 can cause severe bloody diarrhea and haemolytic uraemic syndrome. Phage typing of E. coli O157 facilitates public health surveillance and outbreak investigations, ...
  • The ancestral symbiont sensor kinase CSK links photosynthesis with gene expression in chloroplasts.

    We describe a novel, typically prokaryotic, sensor kinase in chloroplasts of green plants. The gene for this chloroplast sensor kinase (CSK) is found in cyanobacteria, prokaryotes from which chloroplasts evolved. The CSK ...
  • Ancient diversification of eukaryotic MCM DNA replication proteins. 

    Aves, Stephen; Richards, Thomas A; Liu, Yuan (BioMed Central, 2009)
    Yeast and animal cells require six mini-chromosome maintenance proteins (Mcm2-7) for pre-replication complex formation, DNA replication initiation and DNA synthesis. These six individual MCM proteins form distinct heterogeneous ...
  • Ancient pre-glacial erosion surfaces preserved beneath the West Antarctic Ice Sheet 

    Rose, K.C.; Ross, N; Jordan, T.A.; Bingham, R.G.; Corr, H.F.J.; Le Brocq, A.M.; Ferraccioli, F; Rippin, D.M.; Siegert, M.J. (European Geosciences Union (EGU) / Copernicus Publications, 2015-02-16)
    present ice-penetrating radar evidence for ancient (pre-glacial) and extensive erosion surfaces preserved beneath the upstream Institute and Möller ice streams, West Antarctica. Radar data reveal a smooth, laterally ...
  • Andean microrefugia: testing the Holocene to predict the Anthropocene 

    Valencia, BG; Matthews-Bird, F; Urrego, DH; Williams, JJ; Gosling, WD; Bush, M (Wiley for New Phytologist Trust, 2016-07-04)
    Summary Microrefugia are important for supporting populations during periods of unfavourable climate change and in facilitating rapid migration as conditions ameliorate. With ongoing anthropogenic climate change, ...
  • Animal geographies II: methods 

    Buller, HJ (Sage, 2014)
    Animal geographies challenge not only the place and placing of the human and the animal but, critically, the methods we use to engage with both in relation. This second review considers the various methodological implications ...
  • Animal Geographies III: Ethics 

    Buller, HJ (SAGE Publications, 2015-04-19)
    There is no animal geography without ethics. The very coupling of the words gives rise to an ethical endeavor; an acceptance that animals have a geography, a making visible of animals within our human geography and ...
  • Animal minds: from computation to evolution. 

    Thornton, A; Clayton, Nicola S.; Grodzinski, U (Royal Society, 2012-10-05)
    In the great Darwinian struggle for existence, all animals must tackle the problems posed by variable environments, be it finding and processing food, recognizing and attracting potential mates, avoiding predators, ...
  • Animal personality: What are behavioural ecologists measuring? 

    Carter, Alecia J.; Feeney, WE; Marshall, Harry H.; Cowlishaw, Guy; Heinsohn, R (Wiley, 2013-05)
    The discovery that an individual may be constrained, and even behave sub-optimally, because of its personality type has fundamental implications for understanding individual- to group-level processes. Despite recent interest ...
  • Animal Research, the 3Rs, and the “internet of things”: Opportunities and Oversight in International Pharmaceutical Development 

    Niemi, S; Davies, GF (Oxford University Press (OUP) for Institute for Laboratory Animal Research (ILAR), 2016-12)
    Stages of drug (and vaccine) discovery and evaluation that involve laboratory animals increasingly occur via scientific collaborations across national borders and continents. Many of those research collaborations are between ...
  • Animating the Carbon Cycle 

    Schmitz, OJ; Raymond, PA; Estes, JA; Kurz, WA; Holtgrieve, GW; Ritchie, ME; Schindler, DE; Spivak, AC; Wilson, RW; Bradford, MA; Christensen, V; Deegan, L; Smetacek, V; Vanni, MJ; Wilmers, CC (Springer Verlag, 2013-09-19)
    Understanding the biogeochemical processes regulating carbon cycling is central to mitigating atmospheric CO2 emissions. The role of living organisms has been accounted for, but the focus has traditionally been on contributions ...
  • Anisotropic diffusion of spherical particles in closely confining microchannels 

    Dettmer, SL; Pagliara, S; Misiunas, K; Keyser, UF (American Physical Society, 2014-06)
    We present here the measurement of the diffusivity of spherical particles closely confined by narrow microchannels. Our experiments yield a two-dimensional map of the position-dependent diffusion coefficients parallel and ...

    Westerman, Lynne; Roddick, James G. (1981-10)
    Sterol levels in dandelion (Taraxacum officinale Weber) leaves were monitored over a period of 19 months. Sitosterol was the most abundant free sterol, followed by stigmasterol, then campesterol. Cholesterol could not be ...
