Ant wars: How native species can win the battle over invasive pests

 

New research using insight from virtual gaming and real-world ant battles shows how native insects can be given an upper hand against some aggressive introduced species, which could help guide non-native invasive ant management.

Dr Samuel Lymbery, who undertook this work as a Forrest Prospect Fellow with The University of Western Australia and CSIRO, Australia’s national science agency, used mathematical models on video game simulations, garnered from Age of Empires II, to illustrate how battlefield dynamics change warfare outcomes.

These concepts were then confirmed in the real-world by observing ant battles between Australian meat ants, a native species, and smaller Argentine ants, a notorious pest.

“What we found from virtual gaming and then real-life ant battles was that mortality in the small armies of Australian meat ants facing off with large armies of non-native Argentine ants was lower in complex arenas and higher in simple arenas,” Dr Lymbery said.

“So, just like for humans, and in computer games, the outcome of ant-wars depends on the nature of the battlefield.”

Dr Raphael Didham, Professor of Ecology in the School of Animal Biology at The University of Western Australia and CSIRO scientist, said social insects such as ants were one of the few species to engage in warfare on the same scale as humans.

“This is because the evolutionary future of the sterile worker ants who do the fighting is invested in the greater good of the colony,” Professor Didham said.

“We used two ant species that clearly differed in their fighting prowess.

“Our first combatant was the Australian meat ant, Iridomyrmex purpureus. These large and beautiful ants are dominant in undisturbed bushland across regional Australia and construct gravelly nests.

“As their enemies, we selected the notoriously invasive Argentine ant, Linepithema humile. These aggressive ants have been introduced to Australia and are comparatively tiny, but live in extremely large, hyper-cooperative colonies.

How modifying the battlefield can dictate victory

Dr Bruce Webber, Principal Research Scientist at CSIRO, said the ant battlefield research could have practical application for non-native invasive ant management.

“Non-native invasive ants are some of the worst pests on the planet, costing the global economy tens of billions of dollars per year,” Dr Webber said.

“Invasive ants like Argentine ants are typically smaller and more numerous than native species, and are often more dominant in disturbed habitats.

“Disturbed environments are often simplified at ground level, with the removal of undergrowth and natural debris creating open battlefields.

“This research suggests that modifying areas where native and non-native ants co-occur, by adding natural debris or other such structures, may tip the balance in favour of our larger native species.”

Dr Lymbery said by modifying natural environments the native ants were given more opportunities to succeed.

“Warfare theory suggests that fewer, stronger soldiers will be more effective when battles are a series of one-on-one duels. But larger armies are more effective when they can surround their enemies and concentrate attacks,” Dr Lymbery said.

“Battlefield complexity can tip the balance in favour of one strategy over another.

“When fighting in tunnels, alleyways, or difficult terrain, it is harder for large armies to surround their opponents, so small forces of strong or savvy soldiers can sometimes succeed.”

Casino Showground Bookings Now Available

 

We are excited to announce that the recently revitalised Casino Showground and Racecourse precinct will commence accepting bookings starting from Monday, June 3rd.

With a generous funding injection of $12.8 million from the Bushfire Local Economic Recovery Fund, alongside contributions from various sources including the NSW Showground Stimulus Program, Drought Communities Funding, Crown Lands, and Council, the total investment in this redevelopment has reached $14.4 million.

This newly enhanced facility boasts a range of features including a spacious undercover arena, an outdoor sand arena, turfed areas, covered stables, and a state-of-the-art racehorse stable complex capable of accommodating up to 80 horses. Additionally, new parking areas for cars, trucks, and floats have been added for the convenience of visitors.

Of notable appeal is the newly constructed racehorse exercise area, which includes round yards, a horse walker, and a 50-metre equine pool. These amenities are expected to draw considerable interest from equestrian enthusiasts and event organizers alike. Furthermore, enhancements such as powered event camping areas have expanded the facility’s versatility, allowing for hosting a diverse range of events including country music festivals, car shows, trade exhibitions, and markets.

Despite the official opening ceremony held on April 20th to commemorate the acknowledgment of government funding, certain essential construction tasks remain pending due to unforeseen circumstances. These include the high-voltage power upgrade, completion of the equine training area, and fencing installations crucial for ensuring the safety of all facility users.

Unfortunately, adverse weather conditions in the Northern Rivers region have exacerbated delays, saturating many areas of the facility and rendering them unsuitable for immediate use. However, efforts are underway to expedite the finalisation of these outstanding projects in alignment with the originally tendered project costs.

In tandem with these developments, the Council is set to deliberate on its Draft Revenue Policy for 2024-2025 at its upcoming meeting. This policy will outline the proposed fees for utilising the facility and will undergo a public exhibition period of 28 days following the meeting, during which community feedback and submissions will be welcomed.

We extend our gratitude to all existing stakeholders and potential users for their patience throughout this project’s completion, which has been hampered by unforeseen challenges. We eagerly anticipate opening all elements of this facility to serve the broader community.

For those interested in booking the venue, please visit the Council’s venue hire website.
