Corals roll with the punches
A new study suggests corals may be able to cope with climate change in the coming decades better than previously thought—but will still struggle with ever-faster rates of climate change. Lead aut

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.

Abstract: Ecological conditions on coral reefs are shifting. Fishes are an integral part of these restructuring ecosystems and can support ecological stability. However, the extent to which fishes wi

Abstract: Contemporary global changes have put the capacity of future reefs to continue providing fish and fisheries production in jeopardy. Understanding future trends will require innovative and ac
Abstract: No-take marine reserves are a cornerstone of marine ecosystem management in Australia, though they are rarely considered as an effective fisheries management strategy. Yet, by accumulating
