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 and are investigating the genetic basis for resilience and susceptibility to temperature stress in abalone.  Jan also works on marine species that are shifting range in response to climate change and employs eDNA techniques to detect rare and invasive aquatic and marine organisms. 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.

Pearls of wisdom - Breeding for increase tolerance to juvenile pearl oyster mortality syndrome

Indicative Funding
$897,023 over 4 years (administered by Ellies Pearls)
Summary
A decade ago pearl farming was one of the major employers and contributors to the social-economic fabric of northern Australia, contributing $189.7 million farm-gate to the national economy. However, in recent years Australian pearl production has been severely impacted by episodic and large-scale mortality events by an as yet unidentified causative factor. These mortality events, termed juvenile pearl oyster mortality syndrome (or JPOMS), have resulted in massive write-downs in production and economic value of the industry. This project will develop the genetic knowledge and lay the foundation for a selective breeding program in pearl oysters that are resistance to JPOMS.

Testing established methods of early prediction of genetic merit in abalone broodstock

Indicative Funding
$85,422 over 4 years
Summary
There is a need in the abalone industry to improve production animals. However, abalone are relatively slow growing animals and take several years to reach harvest size. This means that during the establishment of foundation broodstock populations it may be several years before the relative genetic merit of each of the broodstock can be determined and the first selection decisions made. Researchers at JCU have addressed this time-lag problem of obtaining accurate genetic estimated breeding values (gEBV) in other species. They have shown that broodstock gEBV can be estimated accurately from larvae as early as 18 days through the targeting of growth processes at the cellular level that predict genetic-determined long-term growth. This method is as yet untested in abalone, but if successful, has great potential in helping screen broodstock. This project will test the efficacy of this early prediction method in abalone. The impact of this early detection method would be to save costs by assisting in the selection of superior broodstock individuals which would produce faster growing offspring. Currently new broodstock animals are unevaluated with regard to their genetic merit.

Rapid iteration selective breeding: Australia's fish to feed the world

Indicative Funding
$1,090,000 over 3 years (administered by Mainstream Aquaculture Pty Ltd)
Summary
Barramundi - Australia?s favourite fish ? is gaining popularity worldwide as a farmed solution for supply of white fish. The world needs a sustainable source of white fish, as current supply comes from declining wild catch fisheries. Industrial scale farming offers a solution. Success relies on improved seed stock and the Australian Barramundi industry in conjunction with the CRC-P program is tackling this challenge by applying advanced modern genetics to Australia?s barramundi breeding stocks.

United States Navy - Detection of scalloped hammerhead sharks in Apra Harbor and adjacent nearshore waters, Guam using environmental DNA

Detection of scalloped hammerhead sharks in Apra Harbor and adjacent waters, Guam using Environmental DNA

Indicative Funding
$75,366 over 2 years (administered by University of Guam)
Summary
Scalloped hammerhead sharks (Sphyrna lewini) are anecdotally reported in Apra Harbor, Guam, but their spatial and temporal patterns of occurrence are not well understood. Lack of knowledge of population abundance, distribution, and habitat use also extends across the geographic range of the Indo-West Pacific subpopulation. All S. lewini are nationally protected under the Endangered Species Act, and their occurrence within Apra Harbor is of concern to management and conservation strategies and mission-essential operations of the U.S. Department of Navy. This project will determine the temporal and spatial distribution and habitat use of the scalloped hammerhead shark within Apra Harbor and Orote Peninsula nearshore waters.

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.

An investigation of multiple paternity in the endangered narrow sawfish, Anoxypristis cuspidata

Indicative Funding
$7,400
Summary
This genetics-based project will investigate multiple paternity in the endangered narrow sawfish for the first time. Sawfishes are arguably the most vulnerable of all marine fishes. Despite this, most aspects of their ecology and reproductive behaviour are poorly understood. A bycatch event of 25 pregnant females in Princess Charlotte Bay has provided a rare opportunity to explore multiple paternity in this species across a large number of litters. Using neutral molecular markers (microsatellites), this study will fill an important knowledge gap and provide information critical to effective conservation and management of this endangered species.

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.
