    Notes: Zusammenfassung Der Tabakmosaikvirus vermehrte den Gehalt an Protein- und Peptidstickstoff in den befallenen Tabakblättern, wirkte aber weder auf die totalen Kohlehydrate noch auf die Kohlehydratfraktionen. Hingegen wurde eine gewisse Beschleunigung der Glukosanbildung nachgewiesen, ein Phänomen, das von einer gleichzeitigen Abnahme der Galaktosanbildung begleitet war.

    Effect of benzoic acid and its hydroxy-derivatives on the carbohydrate-metabolism of starved and of sucrose-fed etiolated barley leaves (1965)
    Springer
    Planta 64 (1965), S. 20-27

    Notes: Summary In etiolated barley leaves benzoic acid and its hydroxy-derivatives lowered the rate of carbon dioxide output, o-hydroxybenzoic acid (OHBA) being most effective, while p-hydroxybenzoic acid (PHBA) was least. Sucrose furthered the inhibitory effects of these acids when they were administered in 0.01 M concentration, but seemed only to alleviate the effect of PHBA when the latter was present in 0.001 M concentration. High concentrations of BA or its hydroxy-derivatives caused the excretion of hexoses, more prominently in the presence than in the absence of sucrose; OHBA being the exception, where sucrose stopped hexose-excretion. In the presence of lower concentrations BA retarded, while OHBA accelerated sucrose-uptake. BA and its hydroxy-derivatives depleted the tissue of its sucrosecontent and lowered the polysaccharide value, whether the leaves were starved or sugar-fed.

    Effect of colchicine on the carbohydrate metabolism of mycelial felts of cunninghamella Sp. (1963)
    Springer
    Archives of microbiology 46 (1963), S. 296-304

    Notes: Summary An experiment is reported in which 5 days old Cunninghamella spec. mats were incubated at 25°C over Richard's medium alone or together with colchicine. The results show that, up to 20 p.p.m., colchicine had no effect on dry weight and soluble sugar content of the fungal mats but caused an acceleration in the rate of sugar absorption and utilisation and polysaccharide accumulation especially the glucosans. 10 p.p.m. concentration further induced an increase in CO2 production and synthesis of mononucleotides and nucleoproteins as indicated by excessive accumulation of conjugated pentoses and the pentosan fraction of polysaccharides.

    Effect of colchicine on the nitrogen metabolism and fate of phosphates absorbed during the formation of fungal felts of cunninghamella sp. (1963)
    Springer

    Topics: Biology
    Notes: Summary During formation of fungal mats of Cunninghamella sp., colchicine seemed to have no effect on the mycelial dry weight but increased the phosphorus and nitrate uptake only when present in 20 p.p.m. All treatments increased the organic phosphorus content and peptide fraction of the tissue medium systems. These phenomena were furthered by raising the concentration of the drug. Colchicine showed its inhibitory effects on protein synthesis only when administered in the high concentration. The mechanism of nitrate utilisation in presence of colchicine was also discussed.

    Colchicine after-effects on the absorption and utilisation of sucrose by Cunninghamella sp. (1964)
    Springer
    Archives of microbiology 48 (1964), S. 185-202 
    Details
    ISSN: 1432-072X

    Topics: Biology
    Notes: Summary Colchicine had no significant effects on the rate of growth of Cunninghamella when administered in 5 p.p.m. concentration; at 10 p.p.m., it induced a slight increase, while at higher concentrations it lowered the dry weight. Pretreatment with colchicine, during the fungal growth induced a persistant activation of hexose phosphorylases, particularly fructose phosphorylase; more promenantly by the continuous supply of the drug than during the recovery on Richard's medium; a phenomenon that might be partially or wholly alleviated by transfer of the treated mats to Richard's solution alone. In all cases the CO2 output of the treated samples was unaffected by the drug except at higher levels (20 p.p.m.). Colchicine treatment favoured the accumulation of polysaccharides; the rate of accumulation depended entirely on both the dose and duration of administration. Furthermore, lower concentrations of the drug favoured nucleoprotein formation but had no effect on nucleotides while the higher concentrations reduced both fractions: a phenomenon that persisted whether the tissues were continuously fed with the drug or recovering on nutrient solution alone. The changes in the metabolic pathways of the absorbed sugars have been thoroughly discussed.

    Colchicine after-effects on the absorption and utilisation of phosphates and nitrates by mycelial felts of Cunninghamella sp. (1964)

    Notes: Summary Colchicine at 5 and 10 p.p.m. increased both phosphorus uptake and incorporation into organic forms (nucleoproteins or other simpler organophosphorus compounds). Continuous supply of colchicine at 20 p.p.m., almost checked phosphorus uptake during the second 24 hours of the experiment. The absorbed nitrates were utilised through the classical reduction steps. It appears also that colchicine had an inhibitory effect on the nitrite reductase that increased by increasing the concentration of the drug. Continuous supply of colchicine at its highest concentration (20 p.p.m.) checked completely the protein building during the second 24 hours of the experiment, though nitrate absorption continued; a phenomenon that caused the accumulation, in the tissue medium systems, of large amounts of peptide nitrogen. The mechanism of nitrate reduction as affected by colchicine treatment was fully discussed.

    Effect of black snake (Walterinnesia aegyptia) venom on the respiratory activity of some tissues of the rabbit (1964)

    Notes: Conclusion As the venom was found to activate all the tissues of the body and it has no specific effect on certain tissues, one can deduce that it must contain factors which affect the respiratory enzyme systems of the body stimulating them and causing increase in their oxygen consumption. As a result of this activation the animal when injected with the venom is subjected to both hypoglycaemia and oxygen lack. In the present experiments, one concentration of the venom was uesd, the effect of different concentrations, the nature of the active principle in the venom causing this activation, and the way of its action on the tissues are under investigation.

    To sing or not to sing: seasonal changes in singing vary with personality in wild great tits (2016)
    Oxford University Press
    Details
    Publication Date: 2016-05-12
    Description: Expression of sexually selected signals in many species varies over time of day and season. A key model system to study this variation in signal expression is birdsong. Yet, despite good ecological understanding of why song varies across time of day and season, much of the individual variation remains unexplained. Although some of the interindividual variation in singing depends on the quality or motivation of an individual, it can also vary with other characteristics. Because singing has been shown to vary with personality traits in specific contexts, personality is thus an important candidate to explain part of the variation in seasonal and daily singing. Using a personality-typed field population of great tits ( Parus major ), we here show that singing activity peaked at dawn during the fertile period of the females and that the association between male personality and singing activity depended on the reproductive stage of his mate; faster explorers significantly increased in singing activity during main periods of fertility and maternal investment (egg laying and incubation). Moreover, males with higher singing activity tended to raise more fledglings. Increased singing by faster explorers during key periods of female reproductive investment suggests that faster explorers are more responsive to changes in female reproductive stage, contrasting the general view that faster explorers are less responsive to environmental and social changes. Most importantly, these findings highlight that multiple factors including personality need to be integrated when assessing causes of variation of highly variable sexually selected signal traits.
