The double burden of climate change
A new study on the effects of climate change in five tropical countries has found fisheries are in more trouble than agriculture, and poor people are in the most danger. Distinguished Profess

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.

James Cook University researchers have found brightly coloured fish are becoming increasingly rare as coral declines, with the phenomenon likely to get worse in the future. Christopher Hemingson, a
Researchers working with stakeholders in the Great Barrier Reef region have come up with ideas on how groups responsible for looking after the reef can operate more effectively when the next bleaching
A new study has delivered a stark warning about the impacts of urban growth on the world’s coral reefs. As coastal developments expand at pace around the world, a year-long study of coral on a reef
Abstract: As marine species adapt to climate change, their heat tolerance will likely be under strong selection. Individual variation in heat tolerance and its heritability underpin the potential fo
Abstract: The Reef Ecology Lab in KAUST’s Red Sea Research Center explores many aspects of movement ecology of marine organisms, ranging from adult migrations to intergenerational larval dispersal
Abstract: Macroalgal meadows are a prominent, yet often maligned component of the tropical seascape. Our work at Ningaloo reef in WA demonstrate that canopy forming macroalgae provide habitat for ad
Abstract: Sharks are generally perceived as strong and fearsome animals. With fossils dating back at least 420 million years, sharks are not only majestic top predators but they also outlived dinosa
Abstract: Connectivity plays a vital role in many ecosystems through its effects on fundamental ecological and evolutionary processes. Its consequences for populations and metapopulations have been
Abstract: Evolution of many eukaryotic organisms is affected by interactions with microbes. Microbial symbioses can ultimately reflect host’s diet, habitat range, and even body shape. However, how
Abstract: The past few years have seen unprecedented coral bleaching and mortality on the Great Barrier Reef (GBR) but the consequences of this on biodiversity are not yet known. This talk will expl
Abstract: Molecular approaches have revolutionised our understanding of the systematics and evolution of most branches on the tree of life, including corals. Over the last twenty-five years molecula
