In a world in which it’s still tough to convince many people that climate change is a very real phenomena, figuring out ways to tackle climate change is an even more difficult problem to wrap our heads around. In general, there are two strategies we can use: (1) mitigation (reducing the accumulation of greenhouse gases in the atmosphere) and, (2) adaptation (reducing the vulnerability of societies and ecosystems facing the impacts of climate change).
In my last piece (linked here), I wrote about the effects of climate change on forests. But what about the reverse, and their potential to mitigate climate change? Forests are crucial for climate change mitigation – they literally suck carbon out of the atmosphere. At the same time, forest adaptation will be necessary to avoid degradation of forest ecosystems due to a changing climate: an extremely complex task.

As carbon emissions rise globally, finding ways to reduce emissions and store carbon are coming to the forefront of modern science. Forests are huge carbon stores thanks to the copious amount of photosynthesis they conduct. As climate change increases temperatures, trees become a very important tool in the fight against rising emissions. One study even described forest restoration overwhelmingly more powerful than all other proposed climate change solutions. You might think: “So let’s go and plant trees!” Unfortunately, it’s not so easy.
Mapping co-benefits for carbon storage and biodiversity to inform conservation policy and action (2019) Soto-Navarro et al., Philosophical Transactions of the Royal Society B, https://doi.org/10.1098/rstb.2019.0128
With the world under so many anthropogenic pressures simultaneously, trying to come up with management solutions for different issues can be a problem. Climate change and biodiversity are a great example. Storing carbon is a great way to reduce the effects of climate change, and increasing the range of forests worldwide is a great way to increase carbon storage. Yet the sort of forests that store carbon most efficiently are often poor at promoting biodiversity. They are largely made up of very similar trees, while forests that include brush, scrubs, and other layers often store less carbon, but house more biodiverse communities.
As such, finding areas that are prime specimens for a) storing carbon and b) biodiversity conservation are incredibly important, so that managers at every level (from park rangers right up to the Intergovernmental Panel on Climate Change) can know where interests overlap, and adjust plans accordingly.

Local Adaptation to Biotic Interactions: A Meta-analysis across Latitudes (2020) Hargreaves et al., The American Naturalist, https://doi.org/10.1086/707323
Local adaptation is a process whereby individuals native to a given area are better-suited to live in that environment than foreign individuals, and those local individuals will out-compete foreign individuals. This adaptation to local conditions can range from a predator that is better at finding and catching prey, to a plant that is more efficient than another at taking nutrients from the soil, or to a host that has evolved defenses against a local parasite. Despite a wealth of literature and science that has been dedicated to the study of local adaptation, it is not clear what it is about the environment that commonly drives it.
Early studies of local adaptation measured abiotic (non-living) factors like temperature and the amount of light, but this ignores the fact that all environments include biotic factors like other species and any interactions with them. A small amount of studies have shown that biotic interactions (i.e. interactions with other species) can drive local adaptation, but there isn’t a consensus on how common of a pattern that is. Today’s authors used a meta-analysis of previous studies to test how these biotic interactions affect local adaptation. Read more

2019 was a year in which many changes that our planet is experiencing came to the fore, capped off in December by the Australian bushfires, a phenomenon that scientists predicted would start to occur with increasing intensity at the beginning of last decade. With all the change that our planet is currently undergoing, it’s always worth noting that the discipline of ecology itself has changed as well.
Over 2019 we got to sit down and talk to some pretty exciting people. And whether they were at the forefront of genomics, the science-policy interface, or the wave of inclusivity currently sweeping ecology, they all had some great comments on how ecology has changed over the last few decades.
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)
Anyone who has forayed any small distance into academia will probably understand the following quote by Aristotle.
“The more you know, the more you realize you don’t know.”
According to Stewart Lee, participating in further education means embarking on a “quest to enlarge the global storehouse of all human understanding”. This might be true, yet venturing into academia also means that the more answers you learn to challenging scientific questions, the more questions get opened up. It’s the circle of academic life.

In case you’ve been living under a rock (in which case, stay there, there’s probably less smoke), you’ll know by now that Australia has experienced wildfires over the last couple of months that dwarf what California and the Amazon went through last year.
The Australian bush fires have been widely covered in the media, but let’s do a quick summary of the stats^. Earlier this week, approximately 73,000 square kilometres – around the size of Belgium and the Netherlands combined – have been burnt and over a billion mammals, birds and reptiles have likely been killed. Tragically, 24 people have died as of Monday, three of whom were volunteer firefighters.
So how has the nation – and the world – reacted? The spectrum has been vast, making analysing the reaction no easy task. So today I wanted to have a look at Australia’s (and in a sense the world’s) ongoing reaction to the Australian bushfires as per the Kubler-Ross Five Stages of Grief.
I’m generally not one for retrospectives. And in 2019, that feels like an advantage, considering how much of the world caught fire and how many backwards steps were taken regarding environmental policy.
But to take a more positive look back at the last 12 months, we at Ecology for the Masses have gotten to speak to some pretty inspiring people. One of the best aspects of running this website is that we’re able to sit down on a regular basis and talk to some incredibly prominent and interesting ecologists, managers and even politicians and talk everything and anything about the world we live in and the creatures that inhabit it.
So here are my favourite quotes from the interviews we published in 2019. If you want more context, you can of course check out the full interview by clicking on the names.
