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.
Scientists say a ‘portfolio’ of protected areas within marine parks such as the Great Barrier Reef can help secure sustainable fish populations. Dr Hugo Harrison from the ARC Centre of Excellen
Scientists have developed a new genetic tool that can help them better understand and ultimately work to save coral reefs. “Surprisingly, we still don’t know how many coral species live on the
A new study suggests ‘dead’ coral rubble can still sustain life, with a large number of tiny animals hidden and living amongst the ruins. While the study does not suggest dead coral has the sam
A new study on coral evolution has found climates similar to what we’re seeing today have previously devastated hard-bodied corals—the architects of coral reefs—while making way for their softer
Abstract: When abundant, seabirds feeding in the open ocean transport large quantities of nutrients onto islands, enhancing the productivity of island fauna and flora. These nutrients can leach int

Abstract: Globally, coral reefs are under threat. Unfortunately, the rate of ecosystem degradation often surpasses the rate of generation of knowledge required to support management. Despite the consi
