A couple of weeks ago I gave a talk at the Insect Ecology Research Chapter workshop at the Ecological Society of Australia’s annual conference in Brisbane. I talked about how policy and popular media influence insect conservation in Australia; as an example, I discussed this research by Toby Smith and me showing how introduced honey bees dominate mainstream media coverage of pollinators in Australia.
I also collated data on which insect species are officially listed as threatened species in Australia. In Australia, we have a national list (under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999) of flora and fauna species that are considered threatened at a national scale. In addition, each individual state and territory has its own threatened species list under various state legislation. Continue reading
Early career researchers are often bombarded with career advice, solicited or unsolicited, from supervisors, peers, senior colleagues, family members, journals, random people on social media; sometimes this advice is helpful, sometimes it’s so ambiguous or outdated it can be potentially damaging.
This article in Nature’s Careers section covers a recently published study in the Royal Society’s journal Interface. The study considers the careers of physics researchers, based on this dataset of authors that have published in the American Physical Society’s three Physical Review journals. The study also looks at Nobel Prize winners in physics. So already, we have two very narrow subsets of ‘researchers’ within a single discipline.
The study found that the focal researchers (i.e. physics researchers who published in APS journals or who won a Nobel Prize) who moved overseas had more citations & therefore greater ‘impact’ on their field. In contrast to the media coverage, the author discusses the results by framing them within contemporary political discussions about immigration, cleverly highlighting that supporting migration from other countries boosts the host country’s social and intellectual capital. This is a completely valid point.
However, the converse is rarely true: you, an individual researcher, don’t have to move overseas to have an impact on your field. Continue reading
We are suckers for hype. The recent media sequel of the mythical Insect Armageddon and the coverage of the latest WWF report on wildlife declines are a reminder of this.
Global declines in insect populations are a huge concern. Insects contribute to myriad ecosystem services through a multitude of ecological processes and functions. If we lose insects, we WILL suffer. But the two studies media have hyped on this issue are not actually evidence that this happening. They are concerning; they are a wake-up call; they are worrying. But, in and of themselves, they are not evidence of apocalyptic declines in the number of all 1+ million species of insect on Earth.
Similarly, the recent WWF report does not show any evidence that humans have ‘wiped out’ 60% of all animals on Earth in the last 30/40 years, as many media outlets are claiming. The truth: the report considered around 4000 species of mammals, birds, fish, reptiles and amphibians…i.e. vertebrates. There are at least ~400,000 more species of vertebrate on Earth (depending who you talk to), probably more. And huge caveat!… Invertebrates are the most abundant and diverse group of animals, so any claim about ‘all animals’ that doesn’t include invertebrates is automatically dubious. Continue reading
Last year I wrote about the Insect Armageddon story – an important paper that received some exaggerated media hype.
A new paper just published in PNAS adds another twist to the insect declines saga…clearly, this story is far from over.
Lister & Garcia analysed data collected in the Luqillo Experimental Forest in Puerto Rico. This area of tropical rainforest is not a ‘pristine’ untouched wilderness, as some media reports are claiming – no place on Earth is untouched by humans! The site has been a long-term research location for decades, going back to the early 1900s, with a focus on experiments to understand the effects of disturbances of all kinds. Many important experimental research projects involving human disturbances (like this one) have happened in the Luqillo forest.
This study is important for a few reasons. Continue reading
Have you read a research paper where you experience this sequence of thoughts?: Title/Abstract/Introduction (wow! This is a real problem, someone’s finally answered this question), Methods (um, hang on, this sample size/study system/analysis approach doesn’t quite answer this problem…), Results (okay, these results are interesting, but…), Discussion (whoa, rein it in! I can’t find the link between these assumptions or recommendations and the results…).
The paper may be scientifically sound, as far as the methods & results go. The problem is that the authors have chosen a very broad frame narrative, and then confounded that frame with the interpretation of their results. Continue reading
Following on with the theme from my last post, here’s an article I wrote for the latest issue of the wonderful Wildlife Australia magazine.
Scale insects get a hard time. We usually think of them as pests, based on our experience with them in gardens and farms. But if a scale insect is living on a tree in the middle of a forest far from any human community, is it a pest? Or part of a complex web of interactions? Every living thing contributes to ecosystem function somehow and there are lots of interesting interactions that we overlook by focusing on simplistic labels.
