    Comment on "Whole-genome analyses resolve early branches in the tree of life of modern birds" (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-09-26
    Description: Jarvis et al. (Research Articles, 12 December 2014, p. 1320) presented molecular clock analyses that suggested that most modern bird orders diverged just after the mass extinction event at the Cretaceous-Paleogene boundary (about 66 million years ago). We demonstrate that this conclusion results from the use of a single inappropriate maximum bound, which effectively precludes the Cretaceous diversification overwhelmingly supported by previous molecular studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitchell, Kieren J -- Cooper, Alan -- Phillips, Matthew J -- New York, N.Y. -- Science. 2015 Sep 25;349(6255):1460. doi: 10.1126/science.aab1062.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Centre for Ancient DNA, School of Biological Sciences, University of Adelaide, Australia. kieren.mitchell@adelaide.edu.au. ; Australian Centre for Ancient DNA, School of Biological Sciences, University of Adelaide, Australia. ; School of Earth, Environmental, and Biological Sciences, Queensland University of Technology, Brisbane, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26404819" target="_blank"〉PubMed〈/a〉

    Significant concentrations of nitryl chloride observed in rural continental Europe associated with the influence of sea salt chloride and anthropogenic emissions (2012)
    Wiley
    Details
    Publication Date: 2012-05-26
    Description: We present the first measurements of nitryl chloride (ClNO2) over continental Europe. Significant quantities of ClNO2, up to 800 pptv, were measured at a mountaintop field site in Hessen, southwest Germany. ClNO2 was detected during the majority of nights between the 15th August and 16th September 2011, its largest mixing ratios being associated with air masses influenced by sea salt and anthropogenic NOx emissions. ClNO2 persisted in measurable quantities until early afternoons on days with low photolysis frequencies. As a consequence, early morning production rates of Cl atoms could significantly exceed the production of OH via ozone photolysis, likely leading to increased O3 production.

    Contractility of bile canaliculi: implications for liver function (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-29
    Description: Dynamic contractions of bile canaliculi were observed in groups of cultured hepatocytes by time-lapse cinephotomicrography during the early stages of monolayer formation. The contractions, which were forceful and appeared to have a pumping action, may facilitate the flow of bile in the liver's canalicular system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oshio, C -- Phillips, M J -- New York, N.Y. -- Science. 1981 May 29;212(4498):1041-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7015506" target="_blank"〉PubMed〈/a〉

    Cellular transplantation in the treatment of experimental hepatic failure (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-21
    Description: The survival of Lewis rats with D-galactosamine-induced fulminant hepatic failure was prolonged if they were given intraperitoneal injections of single-cell suspensions of liver or bone marrow cells from normal rats. Suspensions of liver cells were also effective in prolonging the survival of rats with ischemia-induced hepatic necrosis. The liver cells did not act by repopulating the recipient liver.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makowka, L -- Falk, R E -- Rotstein, L E -- Falk, J A -- Nossal, N -- Langer, B -- Blendis, L M -- Phillips, M J -- New York, N.Y. -- Science. 1980 Nov 21;210(4472):901-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7001630" target="_blank"〉PubMed〈/a〉

    Auxin-Mediated Sterility Induction System for Longevity and Mating Studies in Caenorhabditis elegans (2018)
    Genetics Society of America (GSA)
    Details
    Publication Date: 2018-08-01
    Description: The ability to control both the means and timing of sexual reproduction provides a powerful tool to understand not only fertilization but also life history trade-offs resulting from sexual reproduction. However, precisely controlling fertilization has proved a major challenge across model systems. An ideal sterility induction system should be external, non-toxic, and reversible. Using the auxin-inducible degradation system targeting the spe-44 gene within the nematode Caenorhabditis elegans , we designed a means of externally inducing spermatogenesis arrest. We show that exposure to auxin during larval development induces both hermaphrodite self-sterility and male sterility. Moreover, male sterility can be reversed upon cessation of auxin exposure. The sterility induction system developed here has multiple applications in the fields of spermatogenesis and mating systems evolution. Importantly, this system is also a highly applicable tool for aging studies. In particular, we show that auxin-induced self-sterility is comparable to the commonly used chemically-induced FUdR sterility, while offering multiple benefits, including being less labor intensive, being non-toxic, and avoiding compound interactions with other experimental treatments.

    Solid waste production from rainbow trout, Salmo gairdneri Richardson, cage culture (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 16 (1985), S. 0 
    Details

    Notes: Abstract. There is increasing concern over the environmental impact of freshwater cage culture, but there is a lack of information on the amounts and nature of the wastes produced. This study presents measurements of the total solid waste arid solid carbon, nitrogen and phosphorus loadings from five Scottish rainbow trout, Salmo gairdneri Richardson, cage farms, and shows a significant input of solids below the cages. The results indicate a considerable variability in solid output which was partly due to variations in the feeding rate of fish with the cages, but was also thought to be due to variations in management on individual farms. The results compare well with other studies on land-based pond and tank systems and provide useful estimates of solid waste loadings for the prediction of environmental impact.

    Behaviour of rainbow trout, Salmo gairdneri Richardson, in marine cages (1985)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Abstract. Underwater television was used to observe the distribution and swimming behaviour of groups of farmed rainbow trout, Salmo gairdneri Richardson, in marine net cages. Undisturbed rainbow trout (mean total length 240 mm) aggregated near the surface, remaining motionless in slack water and formed polarized shoals at higher current velocities. Larger fish (mean total length 317 mm) occupied deeper parts of the cage and were more active during periods of slack water. The results are compared with previous work on farmed Atlantic salmon, Salmo salar L., and discussed in relation to the biology of wild rainbow trout and recent work on exercise, growth and condition in salmonids.

    Asian carp farming systems: towards a typology and increased resource use efficiency (2002)
    Oxford, UK : Blackwell Science Ltd
    Aquaculture research 33 (2002), S. 0 
    Details
    ISSN: 1365-2109
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Resource use efficiency in Asian carp farming systems is analysed based on a survey of 2493 farms of nine countries. Multivariate classification of farms by intensity and diversity identified six farm types: four types of specialized aquaculture farms at different levels of intensity, and two types of integrated agriculture–aquaculture systems. Pond-based, specialized semi-extensive systems (using mainly inorganic fertilizers and feeds of off-farm origin), and integrated semi-intensive systems (using feeds and fertilizer of both on and off-farm origin) are by far the most common types, accounting for 59% and 27% of all farms respectively. Specialized semi-extensive systems also show the highest protein and nutrient (N and P) use efficiencies, and among the highest labour use efficiency. Super-intensive cage farms are less efficient in nutrient and labour use, but provide very high returns to land and capital investment. On average, the aquaculture components of integrated agriculture– aquaculture systems are less nutrient, land, and labour efficient than specialized semi-extensive systems. Integrated semi-extensive systems (using organic fertilizers of on-farm origin) are particularly inefficient across all indicators. Hence in practice, gains in overall resource use efficiency through on-farm integration with agricultural production are constrained by the relative inefficiency of the aquaculture subsystems on integrated farms. Although such systems can likely be improved, integration as such is not a panacea to increasing resource use efficiency. Wide variation in resource use efficiency within all systems indicates potential for substantial efficiency gains through improved management regardless of the fundamental choice of system.
