Report of a saxon wasp nest attacked by a cuckoo wasp
Wolf H., 1986: Report of a saxon wasp nest attacked by a cuckoo wasp. Drosera: 115-117
In Plettenberg, Federal Republic of Germany, a nest of the Saxon wasp, Dolichovespula saxonia (FABRICUS), was found, which had been attacked by the cuckoo wasp, Pseudovespula adulterina (BUYSSON). It contained only 3 combs. The upper one had been built before the attack and consisted of small cells. The comb in the middle was built during the attack and at the inside consisted of large cells, out of which adulterina- .female. were hatching, at the outside it consisted of small cells, out of which adulterina .male. were hatching. The lower, abnormal comb, consisting of small cells, was probably built after the death of the old adulterina-.female. and after the flight of the young adulterina-.female. and -.male. The small cells of all combs were filled up with embryo wasps or had discharged parthenogenetic saxonica-.male. being hatched from eggs laid by saxonica-.female.
Soil densiometry by gamma transmission
: A gamma-transmission technique for measurement of density of soil in situ uses a 137Cs source and a scintillation detector, recording primary radiation only. The method is not sensibly responsive to differences in the chemical nature of soil. The...

In vitro and in vivo analyses of a Phe/Tyr switch controlling product specificity of histone lysine methyltransferases
: The functional significance of mono-, di-, and tri-methylation of lysine residues within histone proteins is under investigation. Evidence from several model organisms suggests that different methylated states of H3 Lys9 (H3K9) are generated by sp...
