C_SE 409521698 Paul Ehrlich Lecture Event - Eventbrite2

You’d think I’d get tired of this, wouldn’t you? Alas, the fight does wear me down, but I must persist.

My good friend and colleague, the legendary Professor Paul Ehrlich of Stanford University, as well as his equally legendary wife, Anne, will be joining us in Adelaide for a brief visit during their annual southern migration.

Apart from just catching up over a few good bottles of wine (oh, do those two enjoy fine wines!), we have the immense privilege of having Paul appear at two events while he’s in town.

I’m really only going to be talking about the second of the two events (the first is a Science Meets Parliament gig with me and many others at the South Australia Parliament on 12 November): a grand, public lecture and Q&A session held at Flinders University on Wednesday, 13 November.

Haven’t heard of Paul? Where have you been hiding? If by some miracle you haven’t, here’s a brief bio:

Paul Ehrlich is Bing Professor of Population Studies Emeritus, President of the Center for Conservation Biology, Department of Biology, Stanford University and Adjunct Professor, University of Technology, Sydney. He does research in population biology (includes ecology, evolutionary biology, behavior, and human ecology and cultural evolution). Ehrlich has carried out field, laboratory and theoretical research on a wide array of problems ranging from the dynamics and genetics of insect populations, studies of the ecological and evolutionary interactions of plants and herbivores, and the behavioral ecology of birds and reef fishes, to experimental studies of the effects of crowding on human beings and studies of cultural evolution, especially the evolution of norms. He is President of the Millennium Alliance for Humanity and the Biosphere and is author and coauthor of more than 1100 scientific papers and articles in the popular press and over 40 books. He is best known to his efforts to alert the public to the many intertwined drivers that are pushing humanity toward a collapse of civilization – especially overpopulation, overconsumption by the rich, and lack of economic, racial, and gender equity. Ehrlich is a Fellow of the American Academy of Arts and Sciences, the American Entomological Society and the Beijer Institute of Ecological Economics, and a member of the United States National Academy of Sciences and the American Philosophical Society.  He is a Foreign Member of the Royal Society, an Honorary Member of the British Ecological Society and an Honorary Fellow of the Royal Entomological Society.  Among his many other honours are the Royal Swedish Academy of Sciences, Crafoord Prize in Population Biology and the Conservation of Biological Diversity (an explicit replacement for the Nobel Prize); a MacArthur Prize Fellowship; the Volvo Environment Prize; UNEP Sasakawa Environment Prize; the Heinz Award for the Environment; the Tyler Prize for Environmental Achievement; the Heineken Prize for Environmental Sciences; the Blue Planet Prize;  the Eminent Ecologist award of the Ecological Society of America, the Margalef Prize in Ecology and Environmental Sciences, and the BBVA Frontiers of Knowledge Award in Ecology and Conservation Biology. Prof Ehrlich has appeared as a guest on more than 1000 TV and radio programs; he also was a correspondent for NBC News. He has given many hundreds of public lectures in the past 50 years.

I hope your jaw just dropped.

Victoria, please don’t aerial-bait dingoes

RE: RENEWAL OF AERIAL BAITING EXEMPTION IN VICTORIA FOR WILD DOG CONTROL USING 1080

Dear Minister,

The undersigned welcome the opportunity to comment on the proposed renewal of special permission from the Commonwealth under Sections 18 and 18A of the Environment Protection and Biodiversity Conservation Act 1999 (Commonwealth) to undertake aerial 1080 baiting in six Victorian locations for the management of ‘wild dogs’. This raises serious concerns for two species listed as threatened and protected in Victoria: (1) dingoes and (2) spot-tailed quolls (Dasyurus maculatus).

First, we must clarify that the terminology ‘wild dog’ is not appropriate when discussing wild canids in Australia. One of the main discussion points at the recent Royal Zoological Society of NSW symposium ‘Dingo Dilemma: Cull, Contain or Conserve’ was that the continued use of the terminology ‘wild dog’ is not justified because wild canids in Australia are predominantly dingoes and dingo hybrids, and not, in fact, feral domestic dogs. In Victoria, Stephens et al. (2015) observed that only 5 out of 623 wild canids (0.008%) sampled were feral domestic dogs with no evidence of dingo ancestry. This same study determined that 17.2% of wild canids in Victoria were pure or likely pure dingoes and 64.4% were hybrids with greater than 60% dingo ancestry. Additionally, comparative studies by Jones (1988, 1990 and 2009) observed that dingoes maintained a strong phenotypic identity in the Victorian highlands over time, and perceptively ‘wild dog’ like animals were more dingo than domestic dog.

As prominent researchers in predator ecology, biology, archaeology, cultural heritage, social science, humanities, animal behaviour and genetics, we emphasise the importance of dingoes in Australian, and particularly Victorian, ecosystems. Dingoes are the sole non-human, land-based, top predator on the Australian mainland. Their importance to the ecological health and resilience of Australian ecosystems cannot be overstated, from regulating wild herbivore abundance (e.g., various kangaroo species), to reducing the impacts of feral mesopredators (cats, foxes) on native marsupials (Johnson & VanDerWal 2009; Wallach et al. 2010; Letnic et al. 20122013; Newsome et al. 2015; Morris & Letnic 2017). Their iconic status is important to First Nations people and to the cultural heritage of all Australians. Read the rest of this entry »





The Great Dying

30 09 2019

Here’s a presentation I gave earlier in the year for the Flinders University BRAVE Research and Innovation series:

There is No Plan(et) B — What you can do about Earth’s extinction emergency

Earth is currently experiencing a mass extinction brought about by, … well, … us. Species are being lost at a rate similar to when the dinosaurs disappeared. But this time, it’s not due to a massive asteroid hitting the Earth; species are being removed from the planet now because of human consumption of natural resources. Is a societal collapse imminent, and do we need to prepare for a post-collapse society rather than attempt to avoid one? Or, can we limit the severity and onset of a collapse by introducing a few changes such as removing political donations, becoming vegetarians, or by reducing the number of children one has?

No, you won’t sacrifice scientific objectivity if you advocate

29 08 2019

marchforscience.png

Despite a lot of rather uninformed people out there who might view scientists as just flesh-covered automatons lacking the customary set of feelings, we are in fact normal human beings embedded in the same society as everyone else. We own houses, drive cars, have sex, have children, eat out in restaurants, drink, dance, vote, pay taxes and utilities, do sport, take vacations, see the doctor, laugh, cry, love, and all the rest of it.

As such, we have just as much stake in society as everyone else, and we are very much at the mercy of government policies, cultural norms, and other limitations that everyday life presents us. If we happen to discover through our research some aspect of our society that can be approved, does it suffice merely to publish the material within the academic literature and nebulously ‘hope’ someone else does some good with it?

It is a short, metaphysical step to entertain the idea of advocating for change more proactively than a random Tweet or a newspaper interview might imply. I appreciate that the ‘a’ word strikes fear and derision in the hearts of many scientists, for I too was once under the impression that it was not my job to advocate for anything beyond good scientific practice. Indeed, I practically insisted that my role was uniquely to develop the tools, collect the data, design the experiments, and elaborate the intricacies and complexities of the results to test hypotheses. No more. No less.

Even the thought of mimicking those placard-holding street protestors (my rather naïve impression of what an advocate looked like) used to revile me, for I had formed the (incorrect) opinion that any scientist who took up the protestor’s mantle had clearly abandoned her claim to be an intellectual.

In my view, once one crossed that intangible line into advocacy, the objectivity of all previous intellectual pursuits was immediately compromised, if not abandoned entirely. For me then, ‘advocacy’ equalled ‘subjectivity’, and that was not consistent with what I understood science to be.

I have since done a 180-degree turn on that innocent and narrow-minded perspective. First, I have since come to realise that true objectivity is beyond the reach of any human being, and that science can only provide the tools to reduce our innate subjectivity. As human beings, even scientists have all of our species’ weaknesses and limitations of perception, but science allows us to get as close to objectivity as is humanly possible. So, science is not the pursuit of objectivity per se; rather, it is the pursuit of subjectivity reduction. Errare humanum est. Read the rest of this entry »





10 things I wish I knew before doing an Honours degree

19 08 2019

ORIGINALLY PUBLISHED ON THE GE.BLOG

1*rIJq-egkw9wL-D9ZGsF54g

In 2018 I started my Honours degree in biodiversity and conservation at Flinders University. I had completed my Bachelor of Science in 2017, after being accepted in the Honours stream through my Year 12 Australian Tertiary Admission Rank (ATAR).

I will not sugar-coat it — I was a bad Bachelor student. I scarcely attended classes and at times submitted sub-par work. I believed that as long as I didn’t fail anything I would still be able to do my Honours, so I did the bare minimum and just got by. However in the last semester I discovered I needed an average GPA of 5.0 to secure my Honours position, regardless of what stream I was doing. Panic ensued, I was already too deep in my final semester of not achieving to pull my grades around. Thankfully, I was eventually accepted, after having to plead my case with the Honours board.

In the end I managed to score myself a First Class Honours and a PhD candidature (and hopefully soon a publication). Honours was definitely a struggle, but it was also one of the best experiences of my life. I just wish I had known these 10 things before I started …

1. You will fail

Not the brightest note to start on, but don’t fear, everyone fails. Honours is full of ups and downs, and at some point, somewhere along the line, something in your project will go wrong. But it’s okay! It happens to every person that has ever done an Honours or a PhD. Whether the failing is small or catastrophic, remember this happens all the time.

More importantly your supervisor or co-ordinator sees it all the time. The best thing to do is tell your supervisor and your co-ordinator early on. It may be a simple case of steering your research in a slightly new direction, changing the scope of your project, or even taking some extra time. It’s okay to fail, just keep pushing.

The (not-so) funny question of whether scientists should be political leaders

15 08 2019

67401945_2509778735770137_9029097557816508416_n

At the risk of precociously setting fire to my powder keg, I thought it would be interesting to discuss the very real question of whether there should be more scientists in politics.

The reason I’m contemplating this particular question is because I’ve been forced to. Perhaps contrary to better judgement, I’ve agreed to take part in a the SciFight Science Comedy Debate in Adelaide on 31 August. Organised by scientist-comedian Alanta Colley, the event will pitch two scientist-comedian teams against each other to argue either in the affirmative or negative regarding this — scientists should rule the world.

Of course, the primary goal of the evening is to make people laugh (which still has me wondering whether I was a worthy choice for the role — thank Cthulu there will be some actual, live comedians there too).

But there’s a serious side to this question that I don’t think has any simple answers. Read the rest of this entry »





“Overabundant” wildlife usually isn’t

12 07 2019

koalacrosshairsLate last year (10 December) I was invited to front up to the ‘Overabundant and Pest Species Inquiry’ at the South Australian Parliament to give evidence regarding so-called ‘overabundant’ and ‘pest’ species.

There were the usual five to six Ministers and various aides on the Natural Resources Committee (warning here: the SA Parliament website is one of the most confusing, archaic, badly organised, and generally shitty government sites I’ve yet to visit, so things require a bit of nuanced searching) to whom I addressed on issues ranging from kangaroos, to dingoes, to koalas, to corellas. The other submissions I listened to that day were (mostly) in favour of not taking drastic measures for most of the human-wildlife conflicts that were being investigated.

Forward seven months and the Natural Resources Committee has been reported to have requested the SA Minister for Environment to allow mass culling of any species (wildlife or feral) that they deem to be ‘overabundant’ or a ‘pest’.

So, the first problem is terminological in nature. If you try to wade through the subjectivity, bullshit, vested interests, and general ignorance, you’ll quickly realise that there is no working definition or accepted meaning for the words ‘overabundant’ or ‘pest’ in any legislation. Basically, it comes down to a handful of lobbyists and other squeaky wheels defining anything they deem to be a nuisance as ‘overabundant’, irrespective of its threat status, ecological role, or purported impacts. It is, therefore, entirely subjective, and boils down to this: “If I don’t like it, it’s an overabundant pest”. Read the rest of this entry »
