1/5 #SeaTurtleTalks #TurtleTuesday Ex-situ #conservation in hatcheries is a successful strategy for the recovery of sea turtle populations; but alters biological systems important for hatchling survival. We assessed the effect of ex-situ management on the IIR in olive ridley
2/5 The innate immune response (IIR) was evaluated by spleen histology and the heterophile/lymphocyte ratio. Additionally, morphometry was performed, gonadal sex was determined and sand temperature was recorded during the incubation period.
3/5 Hatchlings from ex-situ nests were heavier, larger and showed a greater spleen-somatic index. They also showed more and better defined periarteriolar lymphoid sheaths (PALS), as well as a higher H/L ratio than those from in-situ nests.

Automatic identification of immature green turtle behavior from accelerometer reveals key marine conservation area in the Caribbean

Accelerometer records animal movement & body posture. Signal interpretation can be difficult & limits its use on #seaturtle
2/7 We deployed multi-sensor recorders (accelerometer, gyroscope and time-depth recorder) combined with animal-borne video-recorder to validate the signal on immature green turtles in Martinique.
3/7 From labelled signals, we trained a #deeplearning algorithm, #Vnet, to automatically identify green turtle #behavior.

🚩High ability to detect behaviors with low discriminative signals such as Feeding and Scratching, and precision down to one centi-second. #rblt

Colonial conceptions of customary tenure continue to inform conceptions of the customary today. The "customary" is not fixed from some time immemorial; it has been reshaped for ideological & political purposes.

🚨New paper! 🚨

.@rini_rants and I interrogate the value and purpose of global maps in #conservation 👉
rdcu.be/cvWOY Image
It's no secret that conservation science (and journals, and the media) loves a good global map - and there's a lot of them. We found >150 global priority maps published since 2000 (and that's DEFINITELY an UNDERestimate) Image
So what? Maps can be super useful, and salient, and have helped (and continue to do so) raise awareness and $ for #conservation

But is there a risk we're overestimating their value? Image

A fantastic moment in Taronga’s #bilby #conservation program was releasing #bilbies to SturtNP Western #NSW as part of the Wild Deserts Project. This large collaboration centres on #reintroduction of locally #extinct species. #SavingOurSpecies #ScienceWeek
The #bilbies are a key part of the Wild Deserts project in #SturtNP and, as ecosystem engineers, are paving the way to #HabitatRestoration across thousands of hectares in #NSW. #SavingOurSpecies PC: Bobby-Jo Vial
The #reintroduction of #bilbies to the wild as part of the Wild Deserts project with UNSW, DPIE and the region’s Traditional Owners, the Wongkumara and Maljangata people, was a great step forward in restoring this western corner of NSW. PC: Bobby-Jo Vial

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
Tracking data revealed hidden #bilby behaviours, such as their little-known social lives! It turns out that #bilbies have quite complex #socialnetworks and that bilby sociality may help explain some of the story behind their post-release success.

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.
To prepare for the #bilby release, introduced predators (#foxes) and herbivores (#rabbits) were detected, removed, and excluded from the 110ha fenced #sanctuary. Detection involved #cameratraps, track plates, and thermal cameras

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 Image
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
Taronga scientists collect and analyse data on wild and zoo-based animals using field-based observation, video footage, #drones, and #CitizenScience. From these data we gain unique insights into both fine-scale movements of individuals, and broad behavioural states of the animals

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 Image
#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
Every animal - #frog, #coral or #rhino - is subtly unique and diversity is key for populations to thrive and be healthy. When populations become small and inbred, or ecosystems suffer too much #biodiversityloss, ecosystems collapse. #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 Image
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.

Bellinger river snapping #turtles are a great example of Taronga’s collaborative work on pathogen discovery and commitment to #conservation. #SavingOurSpecies #WildlifeHealth #ScienceWeek #reptiles Image
When conservation-savvy locals raised the alarm that something was wrong with the #turtles in the Bellinger river, multiple agencies were there to help, including the ARWH who were responsible for finding out what was making these animals sick.
The AWRH found a nidovirus, one that had never been described before. This is also described here by @KarrieARose in a Taronga TV clip:

Through the Myall Lakes Dingo Project, Taronga’s #science team are quickly developing an understanding of the #dingo population. #MyallLakesNationalPark, a beautiful coastal area, has a very pure dingo population of high #conservation value. #ScienceWeek PC: Bobby-Jo Vial Image
Using GPS #radiocollars to keep up with packs, and a comprehensive photo identification library, the team tracks the movements and fortunes of many individuals across several packs. #Dingo pelage patterns, particularly the socks and chest blaze, identifies individuals. Image
We draw these distinctive features on our #dingo ID cards, and use photograph reference photos to identify them. The team are working on making an identikit publicly available, but for now here’s an example for UOM1701 (aka “Bombah Boy”), the dominant male in the Mungo Brush Pack Image

In addition to conducting the #science underpinning evidence-based #conservation tools, Taronga also supports their roll out. For example, Taronga supports a #carnivore #coexistence officer, Tshepo Ditlhabang, on @BPCTrust’s “Re Mmôgô” project in #Botswana #ScienceWeek Image
This #coexistence officer provides the community with access to evidence-based #HWC mitigation tools, including eye-cow, and is working to provide protective livestock collars, and flashing lights (#lionlights) at overnight enclosures. Image
While deterring hungry #carnivores, flashing lights also deter #elephants, themselves a major cause of #HWC but also a vital part of the ecosystem. Research led by @TempeAdams at Elephants without borders showed lights deterred field incursions doi.org/10.1017/S00306… Image

One approach to reducing #HWC and its impacts is to develop tools that promote human-wildlife #coexistence. An eye-catching project conceived by Taronga scientist @HWConflict is one such example. #ScienceWeek PC: Bobby-Jo Vial. Image
By hijacking a common anti-predator signal and applying it in a novel context in #Botswana, the team were able to reduce livestock losses to #lions. nature.com/articles/s4200… PC: Bobby-Jo Vial. Image
The eye-cow approach was very successful in reducing predation by #lions, and Taronga produced detailed “how-to” guides to using the technique with locally available resources, prompting interest and subsequent trials in Peru, USA, India, and Kenya. carnivorecoexistence.info/african-carniv…

#Gorumara National Park is located in the #Dooars region of the Himalayan foothills of #West Bengal.
Jaldhaka a Tributary ofBrahmaputra flows just beside the National Park.
In 1949 it was given a status of a wild life sanctuary. Later on it was declared as National Park in 1994
Gorumara has mixed vegetation of forest & grassland. It is famous for its good population of One Horned Indian #Rhino.
It serves as one of the best places to explore for both animal and nature lovers. This national park is the home to almost 50 species of mammals,
50 species of reptiles and amphibians and almost 300 species of birds. In recent years, there has been a major increase in the number of Elephants, Rhinos and Gaurs (Indian Bison).
The most popular tourist activity is the forest safari.

A thread on Twitter abuse....when I spoke up in Science, with many colleagues, about the #conservation risks of banning trophy hunting (TH) without better options ready, I was totally naive about the backlash, especially on social media. Instructive to look at a little of it 1/12
There are common themes - the first is that anyone who speaks up must be corrupt. I had media coverage of our 0.8% of historic funding from TH orgs - hugely outweighed by funding from groups against TH, but why let truth get in the way of a good story? 2/12
Another common element, trying to tag or approach supporters/donors/employers to try to force them to distance from you. Total disregard for how this could affect real conservation work on the ground, of course, & happily we have great supporters so has not worked... 3/12

Western but more importantly #African #conservation biologists and #communities have clearly evidenced the well managed hunting - inc trophy hunting - is a valid utilitarian conservation tool that is need to protect land from converting to agriculture or development /1
This is because the real and present danger for large and charismatic wildlife in #Africa is habitat loss and quality - including human-wildlife conflict - where #people are effected or killed by such #wildlife and retaliation on wildlife occurs - e.g. /2
While stories of #human hardship in living with #wildlife - and the same dynamics of wanting to develop and use land never reaches UK news - what does is dangerous mis-information from a range of sources but mainly western and #celebrity backed #NGOs /3 conbio.onlinelibrary.wiley.com/doi/abs/10.111…
