The future for sharks: adapt, move, or die
A new study suggests sharks will need to adapt, move or die as climate change could soon render their nurseries uninhabitable. Baby sharks rely on coastal nursery-like spaces such as shallow lagoons

Recently Ohtsuki and Tsuji (2009) has proposed a new hypothesis on the mechanism of evolution of worker policing in social Hymenoptera, which assumes simultaneous operation of intracolonial conflicts over sex allocation, male parentage, and reproductive allocation. A novel prediction of this model is that worker policing will depend on the stage of colony growth and under queen single mating strong worker policing will occur only at the ergonomic stage. In this seminar I will talk about two issues related to this hypothesis. First, I show data strongly supporting Ohtsuki and Tsuji’s prediction in the ponerine ant Diacamma sp. Second, I suggest a proximate mechanism of colony size related behavioral regulation in this ant that is achieved though individual contacts. This is a pioneering study revealing an explicit colony size “sensing” mechanism in social insects.
