open access: yesFrontiers in Ecology and Evolution, 2021
Although indirect selection through relatives (kin selection) can explain the evolution of effectively sterile offspring that act as helpers at the nest (eusociality) in the ants, bees, and stinging wasps (aculeate Hymenoptera), the genetic, ecological ...

Nestmate Recognition in Social Insects: What Does It Mean to Be Chemically Insignificant?

open access: yesFrontiers in Ecology and Evolution, 2020
Social insects use the blend of hydrocarbons present on their cuticle to efficiently distinguish nestmates from aliens. Intruders must therefore find a strategy to break the recognition code in order to exploit the colony resources. Twenty years ago, the

Rossiter-McLaughlin Effect Measurements for WASP-16, WASP-25 and WASP-31 [PDF]

open access: yes, 2012
We present new measurements of the Rossiter-McLaughlin (RM) effect for three WASP planetary systems, WASP-16, WASP-25 and WASP-31, from a combined analysis of their complete sets of photometric and spectroscopic data. We find a low amplitude RM effect for WASP-16 (Teff = 5700 \pm 150K), suggesting that the star is a slow rotator and thus of an advanced
