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

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. #ScienceWeektaronga.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…

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.

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

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.

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.

Another flagship and large collaborative #ConservationBreeding project that Taronga is involved in concerns the #CriticallyEndangered#PlainsWanderer, a bird that few people have probably heard of and even fewer have seen. #ScienceWeek
The #PlainsWanderer has no living close relative, which places it top of the @EDGEofExistence list. Remnant populations of this small ground-dwelling bird are mostly in Victoria, eastern South Australia and in the western Riverina region of NSW.
But this is only part of the #bilby story. How did #bilbies behave once they were released into the Taronga #sanctuary, and did this affect overall success? To find out, we attached GPS devices & radio-transmitters to bilbies to track their movements post-release. #ScienceWeek
GPS devices collected incredibly detailed data on nightly #bilby movements, and radio-transmitters allowed us to locate #bilbies underground during the day. This track shows how bilby “Charlie” used the sanctuary just after release

Once #feralpests were removed and undetected on #cameratraps or other surveys in the Taronga Western Plains Zoo sanctuary for some time, it was time to cut the ribbon, and the apron strings, and release the #bilby founders. #ScienceWeek
Of course, all #bilbies underwent thorough health checks with the Taronga Western Plains Zoo veterinary professionals prior to release. #WildlifeHealth

A flagship project for Taronga is the greater #bilby#conservation breeding program at Taronga Western Plains Zoo in #Dubbo, which is a collaboration with multiple partners, including the @NSWDPIE#SavingOurSpecies program. #ScienceWeek
While the ultimate aim is securing the species in the wild, producing animals fit #ForTheWild and a sanctuary fit to house them in, constitutes a significant amount of the work towards achieving this goal.

In our zoos, we’re constantly observing & monitoring the animals & their environments. We measure sound levels, temperature fluctuations & visitor numbers. Understanding how animals perceive their environments is fundamental to designing & maintaining good zoos. #ScienceWeek
An example of a recent research project in at Taronga Zoo in #Sydney was to look at the so-called visitor effect on our animals. E.g. How do our animals perceive zoo visitors? #HumanAnimalInteractions

As a world-leader in #WildlifeManagement, Taronga continuously improves how we monitor #AnimalHealth & #AnimalWelfare in our zoos & our #conservation programs. This includes tackling the challenges of remotely monitoring, when we can’t have eyes & ears on the ground. #ScienceWeek
Observing #AnimalBehaviour & doing #AnimalHealth checks is only part of the picture. New #tech4wildlife help us identify potential welfare issues in real-time, especially for animals in remote locations, or large groups, or those where immediate up-close assessment isn't possible

In 2021, Taronga embarked on a new critical phase through the support of the #Reef Restoration and Adaptation Program (#RRAP), the world’s largest effort to develop effective interventions to help #coralreefs resist, adapt to & recover from #ClimateChange impacts. @CoralTrace
A fundamental principle of #RRAP is to work closely with #GreatBarrierReef Traditional Owners, and engage different stakeholders, community groups and interests in the co-design, deployment and evaluation of proposed interventions or technologies.
#Coralreefs incl. the #GreatBarrierReef are threatened by ocean warming & acidification, as a result of human-driven #ClimateChange. For an overview of climate projections, the latest #IPCC report takes a deep sobering dive into what's ahead. #ScienceWeekipcc.ch/assessment-rep…#Coralreefs are complex life support systems and their degradation has devastating impacts on marine life and on terrestrial animal populations, including humans. #RRAP

In 2019, a population of Booroolong #frogs was rescued & translocated to Taronga for temporary holding in light of devastating impacts on its environment following prolonged drought & approaching Black Summer #bushfireszooaquarium.org.au/public/Public/…#SavingOurSpecies#ScienceWeek
Time was of the essence! These #frogs live only 3-4 years & were all adults on arrival at Taronga. These critical but ageing founders possess unique genes necessary for their species to adapt and survive in an ever-changing environment.

Taronga’s #science team collaborates on programs that assess and maximise #GeneticDiversity in zoo-based, wild populations, & CryoDiversity Banks (frozen repositories), to promote population resilience & the capacity of species to adapt to change. #RRAP#GeneticDiversity within #wildlife populations relates to long-term survival. Genes affect many things, including body size, #disease, tolerance of temperature extremes, all of which can be important for #CoralReef systems. #Coral#RRAP

#UrbanEcology also plays a key role in forming and maintaining meaningful connections with nature. Maintaining these through adolescence is crucial to #conservation and tackling our environmental issues and the #BiodiversityCrisis. @NSWEducation#ScienceWeek
Our recent research showed that primary kids in #Sydney were more connected to nature than kids in high school doi.org/10.1371/journa… Also, girls were more connected than boys, and were more likely to volunteer for #conservation.
#CitizenScience allows Taronga & collaborators to collate valuable ecological data over scales that would be difficult to achieve through traditional methods. Another plus? It also means that you can get directly involved in Taronga #Science! #ScienceWeek
The #brushturkey project is a great example of this onlinelibrary.wiley.com/doi/10.1111/ae… Taronga's Dr John Martin & Dr Alicia Burns & their collaborators were finalists in the 2020 Australian Museum Eureka Prize for Innovation in #CitizenScience. Go team! #ScienceWeek
