About

Jan Strugnell investigates the evolution and function of marine organisms using genomic and proteomic techniques.  Her research encompasses both applied and blue skies questions. 

Jan applies next generation sequencing tools to help solve bottlenecks in fisheries and aquaculture industries.  Supported by the ARC, her laboratory group is investigating population differentiation, recruitment and adaptation in a range of commercially important lobster species.  They also work on marine species that are shifting range in response to climate change and are investigating the genetic basis for resilience and susceptibility to temperature stress in abalone.  A/Prof Strugnell also investigates population and species level molecular evolution in Antarctic and deep-sea taxa in the context of past climatic and geological change.

A/Prof Strugnell completed her BSc (hons) at James Cook University before obtaining her DPhil at Oxford University, UK, funded by a Rhodes Scholarship.  During her DPhill she used molecular and fossil evidence to investigate phylogenetic relationship and divergence times within cephalopods (octopus, squids and cuttlefish).  A/Prof Strugnell then worked as a post doctoral research fellow at Queen's University, Belfast, the British Antarctic Survey and Cambridge University, UK, where she investigated evolutionary relationships within and between Antarctic and deep-sea octopods.

PhD, Masters, honours and minor projects are available in my group, as below:

The impact of fisheries on genetic diversity and effective population sizes of lobsters (co-supervised with Catarina Silva)

Overexploitation of marine species can result in population decline and have indirect effects on ecological processes such as larval dispersal and recruitment. Lobsters support valuable fisheries around the world but the potential impacts of fisheries exploitation on their genetic diversity are still not well understood. This project will employ high resolution genetic markers (SNPs - single nucleotide polymorphisms) to examine the genetic changes and historical effective population sizes of exploited populations of lobsters. Historical (1967 and 1991) and contemporary samples (2014 and 2015) from three species Jasus paulensis, J. lalandii and J. edwardsii are available for this project. This research will provide crucial information on the impact of fisheries in long term genetic diversity of lobsters, an important body of knowledge to inform management decisions. 

Population genomics of the South African West Coast rock lobster (co-supervised with Catarina Silva)

The South African West Coast rock lobster (Jasus lalandii) supports valuable fisheries but catches have declined markedly since the 1950s. There is evidence that this resource is heavily depleted but knowledge about its population genetic structure is still limited. The availability of high resolution genomic resources has allowed and increase in power to define fisheries stocks and its adaptive characteristics. This project will evaluate genetic structure and connectivity of J. lalandii populations using both neutral and adaptive markers (SNPs - single nucleotide polymorphisms). Understanding neutral and adaptive differences among populations will provide critical information for stock delimitation and management efforts.

Dating the collapse of the West Antarctic ice sheet using next generation sequencing of marine invertebrates

Indicative Funding
$24,432 over 3 years
Summary
This proposal applies a novel biological approach to address a key question for physical scientists. There is great uncertainty in predictions of future sea level rise and recent modelling suggests that forced displacement of over 180 million people this century is conceivable. Predicting the fate of the West Antarctic Ice Sheet is central for accurate sea level predictions The complete collapse of the West Antarctic ice sheet would lead to the existence of a trans-Antarctic seaway linking the present day Ross, Weddell and Amundsen Seas. Such a seaway would allow marine animal migration across newly opened straights, and a persistent genetic signature of historical connectivity of such events will remain in bottom dwelling animals.

Lost at sea? Understanding adaptation and dispersal in spiny lobsters

Indicative Funding
$335,100 over 3 years
Summary
Continual recruitment of young is fundamental to the replenishment of populations, especially when a stock is fished. Existing theory suggests that species with very long planktonic larval stages disperse widely, ensuring their genes are well mixed. However recently identified genetic differences between populations of rock l;obster challenge this paradigm and demonstrate that despite larvae mixing in the ocean for years, local recruitment and/or adaptation are at play. Recent developments in genomics and bioinformatics will allow this project to understand the ecological processes underpinning these genetic signatures and determine their evolutionary implications. Such findings would direct targeted rebuilding of depleted fisheries stocks.1/1/5

Resolving the blue-ringed octopus fauna of Australia: taxonomy, phylogeny and human health

Indicative Funding
$12,000 (administered by Museum Victoria)
Summary
Despite renowned toxicity and human fatalates, knowledge of the blue-ringed octopuses (genus Hapalochlaena) remains poor. Their taxonomy requires through revision: four species are currently considered valid, yet preliminary investigations by the applicants identify a total of at least 15 species worldwide, of which over half occur in Australia. This project aims to use taxonomic and molecular tools to: (1) revise the genus; (2) identify and describe Australian species; (3) describe distributions, habitats and biology; (4) investigate phylogeny and biogeography; and (5) provide crucial identification and health hazard information to scientific and wider audiences.
