Data from: Effective population size in eusocial Hymenoptera with worker-produced males

Tetsuro Nomura & Junichi Takahashi
In many eusocial Hymenoptera, a proportion of males are produced by workers. To assess the effect of male production by workers on the effective population size Ne, a general expression of Ne in Hymenoptera with worker-produced males is derived on the basis of the genetic drift in the frequency of a neutral allele. Stochastic simulation verifies that the obtained expression gives a good prediction of Ne under a wide range of conditions. Numerical computation with...

Akatsuki LIR observing system simulation experiments evaluated by thermal tides in the Venus atmosphere

Norihiko Sugimoto, Yukiko Fujisawa, Nobumasa Komori, Hiroki Ando, Toru Kouyama & Masahiro Takagi
Abstract Impacts of temperature assimilation on Venusian thermal tides are investigated by the observing system simulation experiments assuming Akatsuki Longwave Infrared Camera (LIR) observations. Synthetic temperature data are prepared by a Venusian general circulation model (VGCM) to test if LIR temperature data resolves a discrepancy in the structure of thermal tides between observations and the VGCM. They are assimilated at 70 km altitude with several combinations of frequency and horizontal region. The result shows that...
