    Notes: Summary A thriving, polygynous, and probably overwintered colony of the western yellowjacket,Vespula pensylvanica, was collected on 2 November 1994 in Riverside, southern California, and examined in detail. The colony had 14 combs, of combined area 1.30 m2 containing 55,704 small and 10,266 large cells. There were 17 functional, physogastric queens, 70 newly emerged non-reproductive queens, 7300 adult workers, 685 adult males, and c. 17,600 capped cells containing pupae or fully-fed larvae. Dissections of 200 workers showed that none had well-developed ovaries. Hypotheses for the rarity of polygyny inVespula are put forward and evaluated.

    Notes: Summary: Excavations of 4 nests of the western yellowjacket, Vespula pensylvanica (Saussure) (Hymenoptera: Vespidae) in southern California revealed situations that deviated from the typical annual, single-queen life history of yellowjacket colonies. Three nests that were collected well after colony decline (in December through February) consisted of more queens than workers. An additional nest excavated in April (a time when nests are typically being initiated by single foundress queens) revealed a large polygynous nest that was rearing workers, males, and queens, was very active, and was entering its 3rd year. These life history traits show a plasticity of behavior expressed in the warmer regions of the range of V. pensylvanica and may be more common than previously recorded.

    Notes: Summary: Thousands of individuals in a house-hunting honey bee swarm make a collective decision for one among many nest sites discovered. We recorded the dances on swarms in a forested area, where one swarm's search encompassed about 150 km2 and many different sites. We then analyzed swarms in a desert area with only nest sites that we provided and monitored, to study how the swarm winnows multiple finds to a single site over the course of a few days. Most bees did not visit any site, very few visited more than one. Apparently choices were made with little or no direct comparison, through the interaction of two mechanisms: positive feedback through recruitment leading to growth in the number of scouts visiting good nest sites, and attrition reducing activity and recruitment for non-chosen sites. Individual differences between bees substantially affected these dynamics. Scouts varied considerably in amount of dancing and persistence, but most that danced did so vigorously after their first few visits, and then dropped out, ceasing their dancing though continuing to visit the nest site. Dances were nearly twice as long as reported for nectar and pollen. Scouts followed dances of others, and occasionally visited alternative sites, but rarely switched their dancing. When unanimity is reached, the bees must recognize that a decision has been made, break up the swarm cluster, and fly to the nest site. Buzz-running (Schwirrlaufen) probably plays a role here, but we observed less buzz-running than previously reported, and this occurred even early in the process; it might function as a chain-reaction effect triggering the end of the house-hunting process. Our results suggest that the choice among nest sites relies less on direct comparison of nest sites, and more on inherent processes of positive feedback and attrition by dancers dropping out.

    Notes: Abstract  The mercury (Hg) content of 112 samples of common, wild edible mushrooms was analysed by atomic absorption spectrometry. The average Hg content of all the samples was 1.72 mg/kg dry mass (DM) but the Hg concentrations found in different taxonomic groups (genera and species varied) remarkably. Although different sampling locations obviously have an effect on the Hg concentration of sporocarps, we found evidence for a Hg-accumulating capacity of some taxonomic groups. In addition to Agaricus and Macrolepiota, where the phenomenon of mercury accumulation has already been described, our results indicate high Hg levels in samples of Lycoperdon perlatum (average 2.94 mg/kg DM) and in Lepista species (average 3.02 mg/kg DM). These data confirm the need for greater attention to be given to Hg levels in wild common mushrooms, especially to Hg-accumulating species.

    Description / Table of Contents: Abstract Anxiolysis with drugs and psychoprophylaxis are both recognised methods of preoperative preparation. The beneficial effects of anxiolytics, however, appear to be difficult to prove. In this study a comparison was made of heart rate (HR), blood pressure (BP), and norepinephrine, epinephrine, and cortisol levels. In group I 19 children recieved only psychological treatment, while in group II 21 children received 0.2 mg/kg midazolam orally. Measuring points were directly before medication, 30 min afterward, and at induction of anaesthesia. During the observation period the patients (5–10 years old) remained calm. At the beginning of the study the parameters of all patients were within a normal range; 30 min after premedication the HR and BP were significantly higher in group I than in group II. In contrast to group I, epinephrine levels in group II were lower at the beginning of anaesthesia than before premedication. In both groups, norepinephrine levels were the same at induction of anaesthesia as before premedication. Cortisol decreased only in patients who received midazolam. HR, BP, as well as humoral stress parameters indicate that midazolam in a dose of 0.2 mg/kg orally is sufficient to reduce preoperative stress in children.
    Notes: Zusammenfassung Sowohl Anxiolyse mit Medikamenten als auch psychische Führung sind anerkannte Methoden der präoperativen Vorbereitung. Ein Vorteil von Anxiolytika ist aber für Kinder schwer zu beweisen. Material und Methoden. In dieser Untersuchung wurden Herzfrequenz, Blutdruck, Noradrenalin, Adrenalin und Kortisol als Streßindikatoren zum Vergleich gewählt. Wir betreuten 19 Kinder in Gruppe I psychisch, 21 Kinder der Gruppe II erhielten Midazolam oral (0,2 mg/kg) zur Prämedikation. Die Meßpunkte lagen unmittelbar vor und 30 min nach Prämedikation sowie zu Narkosebeginn. Ergebnisse. Im Beobachtungszeitraum wirkten alle Kinder unauffällig mit vergleichbaren Ausgangswerten. 30 min nach psychischer Führung hatte diese Gruppe signifikant höhere Herzfrequenzen als die Vergleichsgruppe. Analog dazu zeigte sich der Blutdruck. Im Gegensatz zu Gruppe I blieben die Adrenalinspiegel in Gruppe II auch zur Narkoseeinleitung unter den Ausgangswerten. Die Noradrenalinspiegel glichen zu Narkosebeginn in beiden Gruppen der Ausgangssituation. Nur in der Midazolamgruppe blieb Kortisol bis zum Narkosebeginn unter den Ausgangswerten. Schlußfolgerungen. Herzfrequenz und Blutdruck sowie humorale Streßparameter zeigen, daß Midazolam in einer Dosierung von 0,2 mg/kg zu einer Streßreduktion bei Kindern führt.
