Moritz Group - Evolutionary biogeography & conservation

The Moritz Group focuses on evolutionary biogeography and conservation: biodiversity discovery and conservation; biogeography and speciation; biological responses to climate change.

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.

Australia has the world’s worst track record for wiping out mammals, with 34 species declared extinct since European colonisation. But today, we bring some good news: one rodent species, Gould’s mouse (Pseudomys gouldii), is set to be crossed off Australia’s extinct species list.
