The Unseen Effects of Habitat Loss
Whilst climate change continues to hog the limelight, habitat loss remains the key threat to biodiversity worldwide. And whilst events like the Australian bushfires obviously contribute to habitat loss, its main cause is land clearing, whether for agriculture, cattle grazing, mining or urbanization. No matter how many politicians deny or try to deviate attention from it, scientists have shown time and time again just how threatening habitat loss is to our planet’s biodiversity.
On the surface, the process seems quite simple. Habitat goes away, animals lose shelter and food. Yet this is just the tip of the iceberg. Many processes take place below the surface, cascading through an ecosystem. So let’s have a look at the manifold effects of habitat loss, and why it’s the greatest threat to biodiversity today.

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.
The Why and How of Genetic Diversity
Whilst cichlid fish might look incredibly diverse, they are actually all relatively genetically similar. So how do we define genetic diversity, and how do we conserve it? (Image Credit: Emir Kaan Okutan, Pexels Licence, Image Cropped)
Biodiversity has become an immensely popular buzzword over the last few decades. Yet the concept of genetic diversity has been less present in everyday ecological conversations. So today I want to go through why genetic diversity is important, how we define it, and why there is often controversy about its application in conservation science. Read more
5 Stages of Grief and the Australian Wildfires

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.
Extending Ecology – 10 Tips for Interdisciplinary Research
As in nature, its often beneficial for researchers with very different perspectives to bring their distinct backgrounds together (Image Credit: Rickard Zerpe, CC BY 2.0, Image Cropped)
Guest post by Rachel Kelly of the Centre for Marine Socioecology, Tasmania.
Collaboration with other disciplines and knowledges is central to ecology’s capacity to contribute to addressing sustainability challenges in our world today. Interdisciplinary research involves different disciplines working together to integrate their knowledges and methods to meet shared research goals and achieve a real synthesis of approaches. It connects previously disconnected ideas, concepts and resources, and can be a rewarding experience to share collective interest in learning and understanding new perspectives.
Focus on Brexit at BES2019: Resigned But Resolute

I’m in Belfast this week for the British Ecological Society’s Annual Meeting. Whilst I’ll write a more comprehensive summary of the event next week, for now I want to talk (again) about the looming fragmentation that Brexit represents, its impact upon British ecology, and the ecological community in general.
I took a tour of the city on my first day here which focussed on Belfast’s history of violence, and I don’t believe this conference could have had a darker backdrop with regards to Brexit. Fears of a no-deal exit from the EU are sparking worries of the return of a border wall with southern Ireland, which could lead to local redeployment of the British army. Public opinion is starting to sway towards reunification with southern Ireland.
