The Myall Lakes #Dingo Project is a collaboration between Taronga, @CES_UNSW, @UNSW_BEES, NSW National Parks and Wildlife Service through @NSWDPIE, and MidCoast Council, headed up by Taronga’s @HWConflict and @PitcherBen. #MyallLakesNationalPark #ScienceWeek PC: Bobby-Jo Vial Image
Established in 2019, and funded by the Hermon Slade Foundation and Taronga, this project aims to develop and test novel #nonlethalmanagement tools for #dingoes, and to further our understanding and appreciation of this iconic but much-maligned #Australian #carnivore.
#Dingoes and other #carnivores often communicate territory ownership through #scentmarking and #howling. Sound up for this clip! It's a half-hearted howl, but lovely to hear.
Specifically, we’re testing whether #dingo #scentmarks and howls can be used in the absence of #dingoes to deter them from areas of risk or conflict, and keep them safe - while potentially also repelling introduced #foxes. Image
Why repel #dingoes? As with all apex #carnivores, dingoes are beneficial to have around, but they can also be costly to live alongside. Their impacts need to be managed, with the best #animalwelfare and ecological outcomes in mind. Of course, human behaviour also needs work... Image
Current management of #dingo impacts tends to focus on exclusion, either through fencing or #lethalcontrol. As well as removing #dingoes, they also remove any impacts that the carnivore has on the environment (both positive and negative) and can be very costly to implement.
Coexisting with dingoes can be challenging and costly, and while some #nonlethalmanagement tools exist, there’s definitely room for more doi.org/10.7882/AZ.202… and greater uptake. PC: Bobby-Jo Vial. Image
If successful, non-lethal tools would allow managers to target #dingo exclusion in specific areas where the risk of #humanwildlifeconflict is greatest - so perhaps campgrounds, or paddocks - not the entire landscape. This short video explains the project:

Taronga’s marine scientists, in collaboration with Macquarie Uni & others internationally, are investigating the effects of pulsed electric fields on #shark physiology & behavior to deliver innovative improvements in deterrents to save the lives of people & #sharks. #ScienceWeek
This @ARC_gov_au funded project builds on a previous ARC LP by this team that uncovered information on #shark vision and demonstrated the effectiveness of counter-illumination (light emitting) devices in deterring shark attacks
The new project (late 2020>) will test the effectiveness of existing & improved personal deterrents against attacks from white, bull & tiger #sharks. This should reduce fatalities by increasing device-use, while also reducing the need for indiscriminate meshing/culling programs.

Taronga scientists also manage the Australian #Shark Attack File (ASAF). This long-term database & resource provides valuable insights on incidents and the effectiveness of possible deterrents. #ScienceWeek taronga.org.au/conservation-a….
Research using ASAF data led by Laura Ryan with Taronga’s Dr David Slip, Macquarie University, DPI and UNSW scientists, generated predictive models for #shark attacks in Australian waters based on environmental conditions. . doi.org/10.3354/meps13…
This paper identified rainfall & sea surface temperature anomaly as key predictors, and is of great value in designing a potential warning system platform that can allow water users to make more informed decisions before entering the water.

As Taronga’s Research & #Conservation Coordinator, & a marine biologist specializing in #ConservationGenetics, Dr Jo Day, wears many hats – & most are waterproof! Jo’s work covers many areas & species, including the little-known Port Jackson #shark... #MarineScience #ScienceWeek
Data from GPS and accelerometer tags fitted to Taronga zoo-based Port Jackson #sharks allowed the team to identify resting & active swimming, as well as feeding behaviour.
Using fine and broad scale #MovementEcology data from these Port Jackson #sharks, #MachineLearning models allowed the team to identify these key behaviours in this elusive #marine #shark species. mdpi.com/1424-8220/20/2…

Getting lost in the crowd can be a problem when you’re an #endangered sea lion pup. Taronga behavioural ecologist @PitcherBen & collaborators are decoding #Australian #sealion communication to understand how mothers and pups recognise each other in a busy colony #ScienceWeek
Australian sea lions use a combination of sound, sight and smell to communicate and recognise their pups. Mothers can use the size and colour patterns in pup coats to help located their offspring in a colony royalsocietypublishing.org/doi/pdf/10.109… @RSocPublishing #AnimalCommunication
Smell is critical to recognition. Mums will smell pups they encounter while searching the colony to confirm which pup is their own offspring. Each sea lion has a unique smell and mums learn the odour of their pup sciencedirect.com/science/articl… #AnimalCommunication

Taronga is also reminding #RegentHoneyeaters how to tweet! Their song has been changing, perhaps due to small fragmented populations &reduced opportunity to learn from adults. Taronga keepers began playing songs to juvenile birds to teach them the right ones to sing. #ScienceWeek
Results are showing that #RegentHoneyeaters that were tutored to sing, either directly by adult birds or by virtual tutoring, had a better chance of surviving in the wild.
We’re now working with researchers at ANU to understand how best to teach birds to sing and why song is important to survival theguardian.com/australia-news…

The #RegentHoneyeater is one of Australia’s most #CriticallyEndangered birds. There are <350 birds left in the wild. For >20y, Taronga has been #ConservationBreeding an insurance population. Since 2008, >300 birds have been released to bolster wild populations. #ScienceWeek
#RegentHoneyeaters are in decline due to threats from #habitatloss and degradation. #Drought, #bushfire, competition, and now even the precariously small size of the remaining population all pose risks to the species’ survival.
Our team of #RegentHoneyeater keepers are experts in #ConservationBreeding these amazing birds. Here specialist keeper Kara Stevens explains our progress at Taronga Western Plains Zoo, Dubbo.
