    VARIABILITY IN THE DIET OF HARBOR PORPOISES (PHOCOENA PHOCOENA) IN SCOTTISH WATERS 1992–2003 (2004)

    Notes: Interannual, seasonal, and regional variation in the diet of porpoises, Phocoena phocoena, in Scottish (UK) waters was studied using stomach contents of animals stranded between 1992 and 2003. Most samples came from the east coast (including many porpoises killed by bottlenose dolphins), with smaller numbers from the west coast and from Shetland. The most important prey types, in terms of contribution by number and mass, were whiting (Merlangius merlangus) and sand eels (Ammodytidae). Multivariate analysis confirmed the existence of regional, seasonal, and interannual variation in diet, as well as differences (i. e., biases) related to cause of death. These differences were further explored using univariate analyses. Sand eels were more important in the summer months (quarters 2 and 3) and on the east coast, whereas gadids were more important in winter and in the Shetland area. Some, but not all, observed trends in the numerical importance and size of prey taken were consistent with trends in abundance and size of fish taken during research trawl surveys. There was some evidence that porpoises 〈1 yr old took more gobies (Gobiidae) and shrimps than did older porpoises. Clupeids (herring Clupea harengus and sprat Sprattus sprattus) formed a relatively small proportion of the diet, but their importance varied from year to year. Although possible methodological biases prevent firm conclusions, it appears that the importance of clupeids in porpoise diet may have decreased since the 1960s, mirroring the decline in North Sea herring abundance. The recovery of the North Sea herring stock in recent years is not as yet reflected in porpoise diet.

    ADVANCES IN MOLECULAR-BASED DIAGNOSTICS IN MEETING CROP BIOSECURITY AND PHYTOSANITARY ISSUES* (2003)

    Notes: Awareness of crop biosecurity and phytosanitation has been heightened since 9/11 and the unresolved anthrax releases in October 2001. Crops are highly vulnerable to accidental or deliberate introductions of crop pathogens from outside U.S. borders. Strategic thinking about protection against deliberate or accidental release of a plant pathogen is an urgent priority. Rapid detection will be the key to success. This review summarizes recent progress in the development of rapid real-time PCR protocols and evaluates their effectiveness in a proposed nationwide network of diagnostic laboratories that will facilitate rapid diagnostics and improved communication.

    Photosynthesis and the influence of CO2-enrichment on δ13C values in a C3 halophyte (1986)

    Notes: Abstract Shifts in †13C of the graminaceous C3 halophyte Puccinellia nuttalliana (Schultes) Hitch. can be induced by salinization. To investigate this phenomenon, three approaches were taken: assay of carboxylases, CO2-enrichment studies, and gas exchange analysis. Although ribulose-1,5-bisphosphate carboxylase activity decreased with salinity, phosphoenolpyruvate carboxylase activity did not increase and its levels were not atypical of C3 plants. When plants were grown at four NaCl concentrations under atmospheres of 310 and 1300 cm3 m−3 CO2, the CO2-enrichment enhanced the effects of salinity on †13C. This is consistent with a biophysical explanation for salt-induced shifts in †13C, whereby there is a steepening of the CO2 diffusion gradient into the leaf. Gas exchange analysis indicated that intercellular CO2 concentrations were depressed in the leaves of salt-affected plants. This resulted from a greatly decreased stomatal conductance coupled with only small effects on intrinsic photosynthetic capacity. Water-use efficiency was enhanced.

    Phenotypic plasticity of stem elongation in two ecotypes of Stellaria longipes: the role of ethylene and response to wind (1994)

    Notes: Using two ecotypes of Stellaria longipes an alpine form with low plasticity and a prairie form with high plasticity, we investigated whether ethylene was involved in the response to wind stress and might be important in controlling plasticity of stem elongation. Stem growth inhibition was positively correlated with concentration of ethephon application and elevation in ambient ethylene in alpine ecotypes, whereas stem growth in prairie plants was stimulated by low ethephon concentrations. When treated with high AVG, the effects were reversed: alpine plant growth was promoted and prairie plant growth was inhibited. Prairie plants exhibited a daily rhythm in ethylene evolution which increased and peaked at 1500 h, and which was absent in alpine plants. Ethylene evolution did not change significantly during the first 2 weeks of growth in alpine plants, whereas ethylene in prairie plants increased significantly during periods of rapid stem elongation. Wind treatment inhibited growth in both ecotypes, but only alpine plants showed a recovery of growth to control levels when wind stressed plants were pretreated with STS. In addition, only alpine plants showed an increase in ethylene evolution in response to wind simulation, whereas prairie plant ethylene evolution did not deviate from rhythms observed in unstressed plants. We concluded that ethylene dwarfs stems in alpine S. longipes in response to wind stress. However, low levels of ethylene may stimulate growth in prairie ecotypes and act independently of wind stress intensity. The contrasting ability to synthesize and respond to ethylene can account for part of the difference in plasticity documented between the two ecotypes.

    Endogenous ethylene does not initiate but may modify geobending–A role for ethylene in autotropism (1983)

    Notes: Abstract. Ethylene production during geostimulation was examined in peduncles of dandelion (Taraxacum officinale). Significant amounts of ethylene were evolved from geostimulated peduncles compared with vertical controls only after geostimulation of 2 h or longer and the extra ethylene arose mainly from the lower portion of geostimulated peduncles. Reduction of the ethylene produced from geostimulated peduncles by pretreatment with ethylene-synthesis inhibitors did not affect or enhanced subsequent geobending. It is proposed that ethylene may control the later stages of geobending and influence the straightening process of autotropism.

    Production of ethylene by gravistimulation: a potential problem with the interpretation of data from some experimental techniques (1990)

    Notes: Abstract. Gravistimulation was investigated as a potential and unwanted component in the interpretation of physiological investigations on plants. Using both seedlings and mature sunflower plants, two situations are described where gravistimulation contributes significantly to the outcome of an experiment not initially designed to include this parameter. The number of adventitious roots formed in derooted seedings decreased when the tops of the plants were allowed to bend over under their own weight, and the effect correlated positively with the rate of ethylene production by non-vertical stems. In droughted mature plants, and increase in leaf and stem ethylene caused by water stress was supplemented by additional ethylene produced in the lower halves of stems. Drought had caused these stem tissues to wilt, become gravistimulated, and thus produce more ethylene. Other situations in which gravistimulated ethylene production and its physiological consequences are likely to be complicating factors in experiments are discussed. It is concluded that procedures that unnecessarily place experimental material in non-vertical orientations should be avoided.

    Notes: Silage made from Blanca white clover was offered ad libitum to four Friesian cows in a 12-week changeover experiment. The silage contained 990 g white clover DM (kg DM)−1 with 254 g DM kg−1 and 243 g CP (kg DM)−1 The pH was 3.98 and the in vitro DOMD concentration 680 g kg−1. The silage was the sole feed in the control treatment; in the other three treatments it was supplemented with barley, soybean meal, and a mixture of these feeds supplying 8.1, 2.7 and 7.8 kg DM per cow respectively. The daily intakes of silage DM were 19.3, 13.5, 17.5 and 13.5 kg per cow, and the daily milk yields were 26.3, 28.0, 28.6 and 27.6 kg per cow on the control, barley, soybean and barley plus soybean treatments respectively. It is concluded that the white clover silage had an excellent fermentation and a large potential for milk production.
