In the Wet Tropics of North Queensland, we’ve been working with the University of Melbourne for over 20 years on understanding plant-animal interactions and long term population dynamics to improve conservation outcomes for the rare tree Ryparosa kurrangii. It seems every time we go into the rainforest to answer a question on Ryparosa we come out with 10 new questions to investigate! 📷: Bruce Webber (@webber.photography) ... ... #botanising #plants #wildlife #ecology #fieldwork #research #theeceteam #universityofmelbourne #biodiversity #nature #environment #rainforest #wettropics #unescoworldheritage #worldheritage #daintreerainforest #discoverthedaintree #PortDouglasDaintree #exploretnq #fnq #thisisqueensland #discoveraustralia #exploreaustralia

Rosewood (Tipuana tipu) is native to Bolivia and northern Argentina, but has been introduced to many countries for use as a fast growing street tree. Mel Trudgen (@meltrudgen) is doing her PhD with #TheECETeam, working with CSIRO and the University of Western Australia, to understand the risk of this tree ‘jumping the garden fence’ and invading native ecosystems. She is looking at the ecology of the whole invasion system, including quantifying climatic limits to growth and drivers of recruitment and expansion. The sulphur-crested cockatoo (Cacatua galerita) uses Tipuana as a food source, and is particularly adept at manipulating the woody fruits to extract the seeds from within. 📷: Bruce Webber (@webber.photography) ... ... #tipuana #rosewood #cockatoo #botanising #birds #plants #plantanimalinteractions #landcare #flora #nature #ecology #biodiversity #conservation #environment #globalchange #invasion #weeds #fieldwork #research #PhD #PhDlife #science #CSIRO #UWA #australia @csirogram @universitywa

We have recently rediscovered a native bee species believed to be extinct! Juliana Pille Arnold, a PhD student in the Ecosystem Change Ecology team, found a female Douglas’s broad-headed bee, Hesperocolletes douglasi, during a survey of insect pollinators in a remnant of banksia woodland at Pinjar in Perth’s northern suburbs. The only other known record of the bee was a male specimen collected on Rottnest Island 80 years ago. The bee had not been seen since then, despite extensive searches, and was officially listed as ‘presumed extinct’ in 1994. This collaborative work involving CSIRO, UWA and the WA Museum highlights the challenges around conservation of bees and other insect pollinators under threat from land clearing and urban development. The bee species had now been added to the list of critically endangered species in Western Australia. This is a wake-up call for the need to act now to protect and manage urban landscapes in order to sustain biodiversity.

The Ecosystem Change Ecology team is proud to be represented by a diverse group of female scientists delivering on a broad range of research areas as part of their PhD studies. From the Banksia woodlands of the Western Australian Swan Coastal Plain, to the remnant vegetation of the WA wheat belt, to the urban forests of our Australian cities, to the islands of Thousand Island Lake in China, Juliana Pille-Arnold, @toriireynolds, @meltrudgen and @shilu.zheng are achieving great things! 📷: Bruce Webber (@webber.photography) ... ... #iwd2019 #iwd #internationalwomensday #womeninscience #botanising #ecology #fieldwork #research #PhDlife #theeceteam #superstarsofSTEM #scicomm #CSIRO #UWA #UQ #biodiversity #nature #environment #WesternAustralia #thousandislandlake #qiandao @csirogram @universitywa

PhD supervisors are curious creatures. They turn up haphazardly on field trips, throw around curly questions, discuss the appeal of obscure tangents, and propose avenues of research that often translate into countless hours of analysis time….! 🤔😉 Luckily we have some very talented students in #theeceteam to help negotiate aspirational and leading edge, yet reasonably realistic research directions. 😃 Across islands in Thousand Island (Qiandao) Lake in Zhejiang Province, China, Shilu Zheng (@shilu.zheng) is doing her PhD with Raphael Didham, Bruce Webber (@drbrucewebber) and Mingjian Yu at UWA (@universitywa) and collaborating with CSIRO (@csirogram) and Zhejiang University. Here we’re studying shifts in the distribution of plant functional traits from the forest edge to the island interior as part of a study exploring the impacts of habitat fragmentation. 📷: Mingjian Yu ... ... #planttraits #fragmentation #forest #research #phdlife #supervisors #plants #ecology #biodiversity #environment #globalchange #international #fieldwork #science #scicomm #scienceimpact #theeceteam #CSIRO #UWA #thousandislandlake #qiandao #instachina #discoverchina #zhejiang #china #chinaaustraliacollaboration

We’re working with Curtin University to investigate how anti-predation tactics change ontogenetically and evolutionary in the King’s skink (Egernia kingii). The King’s skink is a large (up to half a meter) endemic to the coastal south west of Western Australia and surrounding islands. Like many lizards they can autotomise or ‘drop’ their tail as an effective anti-predation mechanism which can later be regenerated. At CMAC Harry Perkins we generated this micro-CT scan showing a tail with the muscle tissue digitally removed. This image reveals several vertebrae distal to where the tail was most recently autotomised, as well as a cartilage rod from a previous regeneration event. 📷: James Barr ... ... #autotomy #lizard #reptiles #egernia #regeneration #ctscan #herpetology #herpetofauna #wildlife #ecology #fieldwork #research #CSIRO #curtinuniversity #phdlife #theeceteam #scicomm @perkinsinstitute @curtinuniversity
