When we think of global warming, we tend to be a bit selfish and think of how it affects us in our daily lives, but the warming temperatures on our planet have the potential to affect the base of all of our food webs, plants (Image Credit: Matt Lavin, CC BY-SA 2.0).
Phenology in a warming world: differences between native and non-native plant species (2019) Zettlemoyer et al., Ecology Letters, https://dx.doi.org/10.1111/ele.13290
The timing of life-history events (such as births, growing seasons, or reproductive period) is called “phenology”, and this aspect of an organism’s life is particularly sensitive to climate change. So much so that changes in the phenology of certain processes are often used as an indicator of climate change and how it affects a given organism.
We’ve talked about the effects of rising temperatures in animals here on Ecology for the Masses, but there is a lot of evidence in the scientific literature for climate change causing a multitude of different changes in the phenology of various plants. Not only does the direction of the change differ (some organisms experience delays in certain events, others have earlier starts), but the size, or magnitude, of the change also differs. The authors of today’s study wanted to examine these changes in the context of an invasive plant species and how it may be able to outcompete a native plant.
When I was a child, I’d often study books of Australian birds and mammals, rifling through the pages to see which species lived nearby. My source of information were the maps printed next to photos of the species, distribution maps showing the extent of the species range. These days, many of these species ranges are declining. Or at least, many ecologists believe they are. One of the problems with knowing exactly where species exist or how they are faring is a lack of data. The more data we have, the more precise an idea we get of the future of the species. Some data is difficult to collect, but yet more data has been collected, and is simply inaccessible.
At the Living Norway seminar earlier this month I sat down with Tim Robertson, Head of Informatics and the Global Biodiversity Information Facility. GBIF is an international network that works to solve this data problem worldwide, both by making collected data accessible and by helping everyday people to collect scientific data. I spoke with Tim about the journey from a species observation to a species distribution map, the role of GBIF, and the future of data collection.
Charismatic species like the bottlenose dolphin are generally easier to find funding for. So what’s it like to work with them as a scientist. I spoke to evolutionary biologist Celine Frere to find out (Image Credit: Jason Pratt, CC BY 2.0)
We’ve talked at length about charismatic species on Ecology for the Masses. They’re the ones that draw in the public, whether they’re cute and fluffy, majestic, or dangerous. They’re generally easier to procure funding for. So what’s it like to work with them?
During a recent visit to the University of the Sunshine Coast, I sat down with Doctor Celine Frere to find out. Celine works with two of Australia’s most charismatic species, the koala and the bottlenose dolphin. We talked about the pros and cons of charismatic species, getting the public interested in them, and the future of global conservation.
The image of the lone polar bear has become almost ubiquitous in step with growing awareness of climate change. So why hasn’t the scientific community been able to convince the world to act accordingly? (Image Credit: cocoparisienne, Pixabay license, Image Cropped)
During the late 1970s, in the wake of intense scientific research showing that chlorofluorocarbons were leading to the depletion of the ozone layer, the world took action. By 1987, the world had seen the signing of the Montreal Treaty, which practically banned the use of CFCs, imposing significant economic costs on those who signed. Since then, the hole in the Ozone layer has retreated. It’s a powerful example of science identifying a problem, finding a solution, and then presenting both the urgency of both to the public. Scientific communication at its best, surely. So with recent steps backward in environmental conservation law worldwide, despite almost global consensus on the negative impact of well-studied worldwide environmental phenomena, is science communication no longer as effective?

When I interview ecologists, there are two themes I always end up gravitating towards; how the earth is changing and how to improve scientific communication with the general public. So when my colleague Stephanie Januchowski-Hartley mentioned she’d recently spoken to a global change ecologist who also happened to be a poet, I jumped at the opportunity.
Professor Madhur Anand is the co-author of Climate Change Biology and the author of A New Index for Predicting Catastrophes, a collection of poems which bridge the gap between poetry and science. Along her way to picking up two Canada Research Chairs and the ICCC Female Professional of the Year award, she has worked with theoretical physicists, poets and mathematicians. I spoke to Madhur about interdisciplinarity, using poetry to connect with the general public, and the future of the planet.
