    Notes: Atypical pigment was observed in pre-flexion, flexion and post-flexion larval Sebastes collected off central California in 1991 and 1992 that otherwise resembled Sebastes jordani. Atypical pigment occurred on the axillary region at the base of the pectoral fin (most prominent on the inner edge of the pectoral fin base adjacent to the gut), on the median and distal regions of the pectoral fin and on the median and distal regions of the pelvic fin. In addition, lower and upper jaw pigment was observed at a much smaller size in these specimens than previously described in the literature. Identifications of these atypical specimens as S. jordani were confirmed using meristic and otolith characters as well as mitochondrial DNA sequence data. The ontogenetic variability of S. jordani is described. Specimens collected north of Point Conception were more pigmented than larval S. jordani described in the literature (collected predominately south of Point Conception), suggesting geographic variation in pigment development during the larval stage.

    Notes: [Auszug] IN a recent communication1, Shen, Korff and Neuburg have reported the tritium contents of three Antarctic snows collected near Ross Island during 1960-61. The concentration, 82 + 8 T.U., for surface snow representing September-early December 1960 they hold to be remarkably high compared with other ...

    Notes: [Auszug] A striking illustration of the improvement in resolution of detail that can be obtained by using the laser is shown in Fig. 1. Harburn, Yeadon and Taylor have developed a method for controlling the effective phase of the light passing through different regions of a half-tone transparency used as a ...

    Notes: [Auszug] Observations of food selection by oryx and Grant's gazelle, and measurements of temperature and humidity, were made during a severe drought in September 1965 on the El Barta plains in the Northern Frontier Province of Kenya. The local cattle, herded by nomadic tribesmen, were absent and thousands ...

    Notes: [Auszug] The summation process is most often carried out with the help of a digital computer; but several alternative methods have been suggested, for example, the special electronic computer designed by Pepinsky1, which presents the result as a contoured electron-density map on a cathode-ray tube. The use ...

    Notes: [Auszug] THE discrepancy between the date of Easter, 1954, April 18 as given by the tables in the Book of Common Prayer, and April 25 as given by the formula of Gauss, arises from a purely artificial contrivance of Clavius, who arranged the reformed calendar, which is thus described on p. 55 of “The ...

    Description / Table of Contents: Zusammemfassung Frühlingsmigranten von Aphis fabae, die ein Bohnenfeld befielen, waren hauptsächlich auf die Bestandsränder beschränkt, wo die von ihnen begründeten Kolonien “Randbefall” bildeten. Der Initialbefall nahm in der auf die primäre Migration folgenden Zeit an Dichte und Ausmaß zu, wobei die Befallsverteilung im wesentlichen die gleiche blieb wie die von den primären Zufliegern erzeugte. Der Innenteil des Feldes wurde allgemeiner befallen, als ein kleiner Teil der im Felde herangewachsenen Geflügelten in den Bestand eindrang und diesen Teil des Feldes besiedelte; jedoch faßte der Befall nicht Fuß. Auf der geschützten Leeseite des Feldes entwickelte sich ein viel schwererer Befall, obwohl die Anzahl der hier festgestellten Migranten nicht größer war als an jeder anderen Seite des Feldes. Es wird daraus geschlossen, daß die verhältnismäßig ruhigen Bedingungen auf dieser geschützten Seite eine größere Flugaktivität der einfallenden Frühjahrszuwanderer gestattete und daher jeder von ihnen eine größere Anzahl von Pflanzen infizierte als die Migranten in anderen Teilen des Feldes. Es wird angenommen, daß physikalische Wirkungen des Windschutzes, z.B. höhere Temperaturen, Ursache dafür waren, daß an dieser Seite größere Kolonien beobachtet wurden.
    Notes: Abstract The infestation pattern in a bean field is related to the effects of shelter on the activity of the migrants and developing apterous colonies.
