Community ecology, as a relatively new discipline, is fraught with challenges. Here, we look at why an hour spent talking about those challenges may make you feel like the PhD student pictured above (Image Credit: Lau Svensson, CC BY 2.0, Image Cropped)

In this series we’re looking at the discipline of ecofeminism and the difficulties it has faced over the last half a century. You can read the introductory piece here, and part two on the difficulties it had defining itself here. Image Credit: C Watts, CC BY 2.0, Image Cropped.
The ecofeminism movement gained steam in the mid-1970s, at least in the Global North. Naturally, it borrowed a great deal from the environmental movements and versions of feminism that were most prevalent at the time. Here I’ll look at how those origins may have initially constrained the inclusiveness of the philosophy, and how it has moved on since.
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.
Scientific understanding is constructed, developed and advanced through open sharing of knowledge generated by scientists worldwide. Yet for years that collective knowledge has only been accessible to those who pay exorbitant amounts of money. Now the pressure is building for publishers to change the system, as more and more scientific communities push to bypass or break down the expensive paywalls that restrict access to global scientific progress.
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, Image Cropped)
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)
