Rivers have played a monumental role in determining where people live. Their importance in providing water, transportation and a raft of other ecosystem services has meant that even today most of the world’s largest cities are situated close to a major source of freshwater, from Sydney to Delhi, Quebec to Karachi.
Yet despite their role in our history, urban rivers today are often facing increasing levels of pollution as a result of human activity. As well as often being a huge tourist drawcard, and an ongoing resource for fishers, joggers and portable BBQ toters, freshwater ecosystems carry a disproportionate number of aquatic species, which makes this trend increasingly worrying.
After meeting at last year’s British Ecological Society Annual Meeting, I got in touch with Dr. Cecilia Medupin, a freshwater ecologist at the University of Manchester. Cecilia works to increase peoples understanding of rivers, including the project Our Rivers, Our City. I asked Cecilia abut our connection with rivers, the challenges they face, and how to inspire research and change in urban rivers.
More than perhaps any other taxa, birds have managed to associate themselves with the beauty of nature. An ecosystem devoid of bird calls just feels like it’s missing something, and whilst tigers, koalas and elephants might be the face of many a conservation movement, you can’t lure them to your backyard or local park with a simple feeder (at least I hope not). The bird-watching community worldwide is massive, and ranges from casual backyard birders to those who are willing to travel far and wide to see a new species.
For bird scientists, there are pros and cons to the public’s love affairs with birds. The bird community is a huge source of information and a great place to raise awareness of conservation issue. Yet at the same time, our idealisation of birds has led to a lot of misconceptions, both about their population health and their private lives.
Professor Dan Baldassare came into bird ecology through a fascination with animal behaviour. The author of the fantastic paper “The Deal With Birds” (which we’ll get into in a subsequent article, Dan has spent his academic career studying the lives of a range of birds, from the striking Northern Cardinal to the incredible vampire ground finch.
I spoke to Dan recently about our relationships with birds, some of the positives that have come from it, and how our perception of them may have blinded us to some of the realities of their lives.
One of the few positives to come out of a recent spate of catastrophic weather events has been the fact that climate change is now nigh on undeniable, and more people than ever are working to prevent its future effects. Yet there are parts of the world in which climate change is more than the progenitor of random disasters, where it has become an everyday reality.
One such area is sub-Saharan Africa. Despite being one of the poorest regions of the world, it’s also a region that has enormous potential for agricultural transformation, helping to solve not only local food crises, but global ones as well. A prominent example is Kenya, where the agricultural sector contributes to over half of the Gross Domestic Product, and provides food and employment for more than 80% of the population. Working for Kenya and other countries in the region is the chance to avoid mistakes made by other regions in the past, as they benefit both from hindsight and improved technology. Yet working against them is that encroaching threat of climate change.
It’s a topic that Assistant Professor Esther Ngumbi, of the University of Illinois has been vocal about. Esther grew up on a farm in rural Kenya, and has witnessed the effects of increased drought and weather variability over the last decade. Esther’s work on food security in Africa has seen her work published in everything from the Journal of Chemical Ecology to Times Magazine.
At 2019’s BES Annual meeting, I got the chance to speak to Esther about everything from African governments to the shifting of climate baselines.

Over the last few months, extenuating circumstances have confined us to our homes, and the areas immediately surrounding them. For those who love nature, being trapped in the city or suburbs might seem like we’ve lost our daily opportunity to explore the ecosystems around us. Yet over recent years, the push to appreciate urban ecosystems and the species that flourish in them has grown. The exploration of urban ecosystems makes up the lion’s share of my PhD. With the increasing urbanisation seen worldwide, we are at risk of getting alienated from nature, unless we actively make an effort to stay in touch – the phrase: “You can’t save what you don’t love, and you can’t love what you don’t know” comes to mind. Urban ecosystems can offer the opportunity to reconnect with nature without having to travel far and wide to find a patch of green.
With this in mind, Sam and I recently had the chance to sit down and talk to author Kelly Brenner. Kelly, whose book Nature Obscura chronicles the many fascinating lives of urban species, has been leading the charge for renewed appreciation of the nature that is available right outside our doorstep, or in the backyards of those fortunate enough to have them. We spoke with Kelly about her new book, our attitudes toward urban nature, and even how useful Pokemon Go is in an urban nature context.

Fascination with nature drives a huge chunk of tourism worldwide. The plains of Africa, the Amazon Rainforest, the Swiss Alps and their associated species are huge economic drivers for their respective countries, and they (ideally) increase people’s appreciation of nature. There are plenty of great examples of ecotourism as a pathway for both education and conservation.
Yet when an industry is driven by money first, nature second, of course there are going to be manifold examples of businesses deprioritising the natural phenomena they are associated with, often to the direct detriment of that phenomena. Think the masses of pollution now found around Mt Everest, or the damage caused by avid snorkellers on the Great Barrier Reef. I’ve had my own experience with tourist companies deliberately spreading misinformation about the reef – more on that at this link.

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.

While climate change and habitat loss seem to keep making all the headlines when it comes to environmental damage, invasive species are still chugging along comfortably as the second biggest threat to our planet’s biodiversity. New cases are popping up all the time, with the Burmese python, Crucian carp and the emerald ash borer beetle recently reaching new levels of notoriety.
Yet the negative impact that many non-native species have on the habitats they move into have often led to stigmatisation of anything new. This can be counter-productive, as the majority of newcomers into an ecosystem won’t have a pronounced negative effect. And whilst it may seem like a smart piece of preventative management to maintain an ecosystem’s status quo by preventing species introductions, it’s often just not feasible.
With this in mind, I sat down at the recent British Ecological Society’s Annual Meeting with Professor Helen Roy of the UK Centre for Ecology and Hydrology. Helen has studied the impacts of non-native species the world over, from the UK to smaller island nations like St. Helena, and has led several projects for the European Commission on non-native species. We spoke about the importance of distinguishing between invasives and non-natives, the impact of climate change on invasive biology, and the social and cultural significance of both native and non-native species.
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.
