Craig Moritz

Craig did his undergraduate at University of Melbourne (1976-1979), where he developed his passion for evolutionary biology. For his PhD at ANU (1980-1985), he studied chromosome evolution and speciation in arid zone lizards, along the way discovering all-female reproduction in Heteronotia binoei. Then he moved across the Pacific Ocean for a postdoc at University of Michigan (1985-1988; mitochondrial DNA and evolution of parthenogenesis), before returning to a faculty position at The University of Queensland (1988-2000), including a stint as Head of School. From 2000-2012 he was Director of the Museum of Vertebrate Zoology at UC Berkeley. From mid 2012 he happily settled at EEG/RSB as a Professor and ARC Laureate Fellow. Craig is the Director of the ANU-CSIRO-UC Centre for Biodiversity Analysis.

 

Research interests

Biodiversity discovery & conservation

The majority of species remain to be discovered, yet habitats are being lost of affected by global change at an ever increasing rate. New tools from genomics, phylogenetics and spatial environmental analysis are revolutionizing our ability to discover diversity and map hotspots of unique species- or phylo-diversity. Building on previous studies of rainforests in eastern Australia and Brazil, and in California, our lab has turned its attention to the monsoonal tropics of Australia -  perhaps the largest ecologically intact tropical savanna on the planet, and also a frontier for biodiversity discovery. Through a combination of field work, genomics, phenotyping and novel spatial analyses we have discovered species and hotspots of diversity new to science and this is now informing conservation strategies by agencies and NGOs. In ongoing work, we aim to better understand the evolutionary processes that generated this diversity and how this knowledge can inform conservation under rapid environmental change.

Biological responses to climate change

Though existing species have persisted through multiple episodes of climate change in the past, we are entering a new phase of rapid, human-caused climate change with no analogue in the recent geological past. Understanding how species respond by migration or adaptation is key to finding strategies to promote persistence of biodiversity. Our lab studies this through a combination of comparative studies of phenotypic and genomic diversity in across environments in space and time. One potential solution is to identify long-term climatic refugia across the landscape - also likely centers of local diversity and seek to protect these and habitat linkages to them. 

Diversity and conservation of Australian marsupials

Australia hosts a globally unique radiation of marsupial mammals, many of which are strongly impacted by invasive species and habitat alteration. We are using genomics and advanced statistical methods to understand species boundaries and relationships across the entire radiation. For species now restricted to islands, we are investing divergence history and genetic erosion in remnant populations that are also the source for translocations to fenced areas on the mainland.

All publications

I welcome bright and highly motivated students with interests relating broadly to any of the above areas. Students are expected to take the initiative to develop their own projects and, over time, to learn to function independently as research scientists. The lab will include research opportunities for outstanding undergraduates, Hons, PhD and postdoctoral scholars. Within currently funded projects, there are specific opportunities for micro- and macro-evolutionary studies of fauna (especially, but not exclusively lizards) across the monsoonal tropics of northern Australia.
