    Notes: Abstract The aim of this study was to determine the effects of nitrogen (N) fertilization methods on root distribution and mineral element concentrations of White Marsh grapefruit (Citrus paradisi MacFadyen) trees on sour orange (C. aurantium Lush) rootstock on a poorly drained soil. At 0–15 cm depth of soil, root density was significantly greater for trees receiving 112 kg N ha-1 yr-1 as dry granular broadcast than those receiving the same amount of N as fertigation. Of the total roots in the top 60 cm soil, 〉75% was at 0–15 cm and 〈10% was at 30–60 cm. Root density was greatest near the emitter. Nitrogen concentration of roots was greater for the trees which received fertigation as compared to the trees which received dry fertilizer broadcast or no N.

    Notes: Abstract The retention and transport of P by three horizon samples (A, E, and Bh) of a Spososol (Oldsmar sand: sandy, silicious, hyperthermic Alfic Arenic Haplaquods) were evaluated using a batch-equilibration and leaching column techniques with application of P in rates equivalent to 25 and 100 kg P ha-1. Adsorption coefficient (K) values followed the order: Bh 〉 A 〉 E. Adsorption of P by the E horizon soil sample was negligible (M = 4 μg g-1 soil) as compared to that of either A or Bh horizon samples, e.g., 303 and 479 μg g-1, respectively. The leaching column study with application of P equivalent to 100 kg ha-1 showed 39, 68, and 98% of applied P were leached from the Bh, A, and E horizons, respectively, with eight pore volumes of leachate. Elution curves showed the peak P elution at the second pore volume (equivalent to 3.7 cm of water addition). After leaching with eight pore volumes, the residual P in the soil was present primarily in non-occluded Fe and Al-P forms in the A and Bh horizons.

    Description / Table of Contents: Résumé L'action d'applications de soufre et de pollen sur les acariens phytophages et prédateurs a été étudiée dans un vignoble non commercial au cours d'une saison végétative complète. Les populations de tydeides (Pronematus sp.) augmentent plus tôt dans les parcelles traitées au pollen et dans les témoins qui ne reçoivent pas de soufre que dans les parcelles traitées 4 et 10 fois avec du soufre. Les populations d'acariens prédateurs (Metaseiulus occidentalis (Nesbitt) répondent rapidement dans toutes les parcelles à cet accroissement du nombre de tydéides. Cependant les densités les plus élevées atteintes par ce phytoseiide dans les lots témoins et avec pollen (1,6 par feuille, et 1,1 par feuille, respectivement) sont le double des densités maxima observées dans les parcelles traitées au soufre (0,6 par feuille), alors que les tydeides sont en nombre comparable partout. Une autre preuve des effets inhiteurs du soufre est fournie par les populations de tarsonémides qui augmentent rapidement en fin d'été dans les parcelles sans soufre mais s'accroissent seulement légèrement dans les lots traités au soufre. Les populations de tétranyques sont restées extrêmement faibles pendant toute la saison. Dans des échantillons de bourgeons prélevés au cours de l'hiver 1971–1972, les nombres deM. occidentalis par bourgeon, ainsi que le nombre de bourgeons dans lesquels ils se trouvent, étaient analogues pour tous les traitements à l'exception des parcelles recevant 10 applications de soufre où on observe une beaucoup plus faible population hivernante. Une relation écologique étroite apparaît d'après cette étude entreM. occidentalis et les acariens tydéides. Le maintien pendant toute l'année, et spécialement en fin d'automne, d'une interaction prédateur-proie entreM. occidentalis et les tydéides, doit contribuer à favoriser la limitation des acariens en permettant l'hibernation d'un plus grand nombre de prédateurs.
    Notes: Abstract The effect of sulfur and cattail pollen applications on predatory and phytophagous mite species was investigated in a noncommercial vineyard for a full growing season. Populations of tydeids (Pronematus spp.) increased earlier in pollen and control plots that received no sulfur than in plots treated 4- and 10-times with sulfur. Predatory mite populations [Metaseiulus occidentalis (Nesbitt)] responded quickly to this increase in tydeid numbers in all plots. However, peak densities achieved by this phytoseiid in the pollen and control replicates (1.6/leaf and 1.1/leaf, respectively) were twice that attained in the sulfur treated plots (0.6/leaf), although comparable numbers of tydeids were present in all plots. Further evidence of the inimical effect of sulfur was provided by tarsonemid populations which increased quickly in late summer in those plots receiving no sulfur, but increased only slightly in plots treated with sulfur. The numbers of tetranychid mites remained extremely low throughout the season. In bud samples taken during the winter 1971–72, the numbers ofM. occidentalis found per bud, as well as the number of buds in which they were present, were similar in all treatments, except the 10-treatment sulfur plots where a much lower overwintering population was found. A close ecological relationship betweenM. occidentalis and tydeid mite species was revealed by this study. The data suggest that the maintenance of a tydeid —M. occidentalis predator—prey interaction throughout the year, and especially in the late fall months to allow a greater number of predators to enter overwintering sites, would contribute to improved spider mite control.

    Description: We present a new set of global and local sea‐level projections at example tide gauge locations under the RCP2.6, RCP4.5 and RCP8.5 emissions scenarios. Compared to the CMIP5‐based sea‐level projections presented in IPCC AR5, we introduce a number of methodological innovations, including: (i) more comprehensive treatment of uncertainties; (ii) direct traceability between global and local projections; (iii) exploratory extended projections to 2300 based on emulation of individual CMIP5 models. Combining the projections with observed tide gauge records, we explore the contribution to total variance that arises from sea‐level variability, different emissions scenarios and model uncertainty. For the period out to 2300 we further breakdown the model uncertainty by sea‐level component and consider the dependence on geographic location, time horizon and emissions scenario. Our analysis highlights the importance of variability for sea‐level change in the coming decades and the potential value of annual‐to‐decadal predictions of local sea‐level change. Projections to 2300 show a substantial degree of committed sea‐level rise under all emissions scenarios considered and highlights the reduced future risk associated with RCP2.6 and RCP4.5 compared to RCP8.5. Tide gauge locations can show large (〉 50%) departures from the global average, in some cases even reversing the sign of the change. While uncertainty in projections of the future Antarctic ice dynamic response tends to dominate post‐2100, we see a substantial differences in the breakdown of model variance as a function of location, timescale and emissions scenario.
