Queen’s Birthday Honours

The 2019 Queen’s Birthday Honours list included two names with a close relationship to the State Herbarium of South Australia: Bev Overton and Peter Copley. Bev received the award of Member of the Order of Australia, and Peter received the award of Public Service Medal.

Back in February 2016, the State Herbarium did a blog article on Kangaroo Island couple Bev and Dean Overton. The story congratulated them for being recognised as Kangaroo Island high achievers for their outstanding efforts in conserving and raising awareness of KI’s natural environment at the Local Achievers Natural Resource Management Board Awards ceremony held on Australia Day that year.

Last year the Herbarium was approached by Kangaroo Island environmental consultant and botanist Michelle Haby to help support a nomination for Bev Overton to receive recognition in the 2019 Queen’s Birthday Honours. The final nomination was put together and submitted by Michelle and Bev’s husband Dean. Sadly Dean died unexpectedly before the news of Bev’s successful nomination was known.

You can read more of Bev’s impressive nomination here (156kb PDF). An article in THE ISLANDER newspaper also appeared recently.

Peter’s medal recognises his contribution and commitment of more than 40 years to help conserve threatened species and ecological communities in South Australia, as well as his role in biodiversity research and policy development. Peter reviewed the daisy genus Ixodia for his Honours at the University of Adelaide and has contributed 3601 collections to the State Herbarium over the years. His interest in botany was no doubt inspired by his father Bruce Copley, a Yorke Peninsula farmer who pursued an interest in his local native flora by collecting and submitting many specimens to the Herbarium.

Manager Peter Canty and Senior Botanist Peter Lang have worked closely together with Peter over many of those years, especially when they were part of the Biological Survey of South Australia program. Peter Copley lead the over decade-long biological survey of the Anangu Pitjantjatjara Yankunytjatjara Lands. The knowledge captured by that survey was greatly enhanced by working with Aboriginal Traditional Owners and Peter’s ability to establish close working relationships with the elders and their communities was pivotal in this particular survey’s success, and being recognised with a SA Great Award in 2003 in the Environment Category for an ‘Outstanding Contribution to South Australia’.

The Herbarium was very pleased to be involved in their nominations and wishes to congratulate them on their well-deserved recognition.

Grasses keys online

Several years ago, the State Herbarium of South Australia published Grasses of South Australia by J.P. Jessop, G.R.M. Dashorst & F.M. James in collaboration with Wakefield Press. This is the well-known standard work on the grass family Poaceae for the State and can also be used in adjacent regions of other States.

KeyBase is a database and web application for managing and deploying interactive pathway keys. It presents traditional dichotomous keys in a new way online. In addition to standalone keys, KeyBase also delivers identification keys to the new  online Flora of Australia and VicFlora.

Keys to the South Australian Flora are currently being added to Keybase. Last week, Kat Ticli from the State Herbarium completed the conversion of the keys to species in Grasses of South Australia and uploaded them to KeyBase. Poaceae is one of the largest plant families in the State. Having this key and others online will enable easy access to this information and be helpful to anyone wanting to identify the native and naturalised grasses of South Australia.

Our botanical bunker

Recently, Chief Botanist, Prof. Michelle Waycott, was interviewed by The Adelaide Review about the history of the State Herbarium of South Australia and its holdings. The resulting article is now available.

Couper, S. (2019). Inside the bunker safeguarding South Australia’s rare plants and botanical history. The Adelaide Review (posted 9 Apr.).

As mentioned in the article, during South Australia’s History Festival, the State Herbarium will also offer guided tours through the old Tram Barn building. Please note that the dates in the above articles are not correct. The tours will take place on Sat., 25 May & Sun., 26 May 2019.

Please go to the History Festival’s website for more information.

The State Herbarium also published the following brochures, which are accessible online:

  • Bell, G. (2012). One million and counting: History and special collections of the State Herbarium of South Australia. (0.5mb PDF).

New eucalypt phylogeny

Last month, Dr Andrew Thornhill started working at the State Herbarium of South Australia.  Originally from Melbourne, Andrew studied and worked at Monash University (Melbourne), the Australian National University, Australian National Herbarium and CSIRO (all Canberra), the Australian Tropical Herbarium (Cairns), the University of California (Berkeley, USA) and the federal Department of Agriculture and Water Resources (Canberra). In his current position, he is working for both, The University of Adelaide and the State Herbarium on a variety of projects, including the analysis of molecular data-sets and re-organisation of the Herbarium’s bryophyte collection.

In 2011, Andrew started a project on creating a complete species level phylogeny of the eucalypts (which include the genera Eucalyptus, Angophora and Corymbia). The idea was to sample DNA for as many eucalypt species as possible, combine that data and see how all of the species were related to each other. This week, over seven years later, the project was published.

There are over 800 described eucalypt species in the world and we are close to soon having 900. Around 1/8th of the total number of eucalypt species are native to South Australia and they grow in the arid and forest areas in an array of habits, be it mallees or trees up in the hills.

The paper presents a dated phylogeny of the Australian eucalypts and a diversification analysis to show if any parts of the eucalypt phylogeny have had accelerated diversification. What Andrew and his colleagues found was that many of the species that grow in the arid and forest areas of southern and south-eastern Australia have only evolved in the last two million years, this includes many of the eucalypt species that grow in South Australia. Their origin comes due to a divergence with Western Australian eucalypts, but that’s not to say that Western Australia is where eucalypts originated. There are even deeper splits in the history of eucalypts that suggests that either south-west Western Australia or south-east Queensland could be the source of origin. One way to find this out may be by finding new ‘oldest’ fossils in either of these places, which would help provide evidence that eucalypts grew there in the deep past.

The results of this research are also discussed by Andrew in an article in The Conversation. The treatment for eucalypts in the new, 5th edition of the Flora of South Australia is also available (33.7mb PDF).

High ranking output

Two scientists from the State Herbarium of South Australia have recently collaborated with colleagues to produce research papers that were published in well-known Nature Research journals during the last week.

(1) T. Varga, et al., Megaphylogeny resolves global patterns of mushroom evolutionNature Ecology & Evolution (16 Mar. 2019), DOI: 10.1038/s41559-019-0834-1.

Hon. Research Associate Pam Catcheside is among 62 authors, collaborating in this global effort to produce a phylogeny of 5,284 species of Agaricomycetes. These mushroom-forming fungi have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfill diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. This ground-breaking, first comprehensive phylogeny of mushroom-forming fungi reveals large-scale patterns of their evolutionary history.

Some years ago, State Herbarium botanist Jürgen Kellermann was contacted by Jesse Kalwij (now working in Germany) to identify an unknown shrub that was discovered about 25 years ago on sub-Antarctic Marion Island, one of the two Prince Edward Islands (South Africa). This evolved into a study examining the pathways that lead to the establishment of the plant, which turned out to be Ochetophila trinervis, a shrub in the family Rhamnaceae (see also this article). The species is native to southern South America, the closest population being over 7,500 km away. Dr Kalwij involved colleagues from South Africa, Australia, Argentina and Germany in this research, identifying the barn swallow as the most likely vector dispersing seeds of the plant to this sub-Antarctic island.
