1. Yearly records of worker Vespula germanica (Fabricius) taken in suction traps at Silwood Park (28 years) and at Rothamsted Research (39 years) are examined. 2. Using the autocorrelation function (ACF), a significant negative 1-year lag followed by a lesser non-significant positive 2-year lag was found in all, or parts of, each data set, indicating an underlying population dynamic of a 2-year cycle with a damped waveform. 3. The minimum number of years before the 2-year cycle with damped waveform was shown varied between 17 and 26, or was not found in some data sets. 4. Ecological factors delaying or preventing the occurrence of the 2-year cycle are considered.

Field observations were made on 37 preworker, multiple-foundress colonies of the social wasp Polistes fuscatus. In total, 401.9 h of behavioural observations of cofoundresses were conducted at three different periods prior to the emergence of workers. Cofoundresses displayed a marked, significant increase in aggression at about the time in the colony cycle when reproductive-destined eggs began to be laid. Both queens and their subordinates became increasingly aggressive at this time. These empirical results support theoretical predictions that conflict among cofoundresses would intensify over the production of reproductive-destined (but not worker-destined) eggs. Cooperation in foraging to minimize nest inattendance as well as synchronicity (temporal overlap) in activity also increased significantly at the onset of the production of reproductive-destined eggs. Thus, conflict and cooperation are not necessarily antagonistic in P. fuscatus. Foundresses minimized the time that nests are unattended at a time in the colony cycle when most conspecific usurpations occur. This suggests that the ecological pressure of conspecific usurpation has favoured increased coordination in foraging to minimize the time nests are unattended. The adaptive significance, if any, of an increase in synchronicity of activity among cofoundresses at the onset of the production of reproductives is not obvious.

Transformation of society inevitably leads to transformation of culture. The relevance of studying the reproductive cultural transformations of modern Russian society is increasing due to the obvious presence of gender crisis at the macrosocial and microsocial levels. Gender stereotyping in procreation is increasingly in confl ict with the variety of masculine and feminine reproductive scenarios, the demarcation of norms and pathologies of reproductive behavior. The gender approach in studying of reproductive behavior in modern Russian men and women in this article is aimed to typologize and analyze masculine and feminine reproductive scenarios – from the most conformal (pronatalistic) to oppositional (antinatalistic). The rejection of the totally naturalistic approach to the interpretation of motherhood and fatherhood in favor of analyzing the sociocultural components of the currently relevant feminine and masculine reproductive strategies is much more responsive to the social needs and the demands of modern humanitarian science.
