Evolution in an Urbanizing World
It is a common belief that human-modified areas, such as farmlands, support fewer bird species than natural habitats such as forests. However, new research by Zhao et al. (2024) challenges this idea. Their study of bird species diversity on islands off the coast of China has unexpected results that suggest that farmlands might play a... Continue Reading →
Many of the posts on this blog discuss the wide variety of life you can find in urban environments. But have you ever considered the diversity you can find in the very stones of the buildings we live in? Depending on where these stones were mined, you might be able to find some neat fossils....

With the rapid expansion of the city, the degradation of the natural environment has gradually aroused widespread concern in society. In recent years, the saguaro cactus (Carnegiea gigantea), one of the most iconic plants in the Sonoran Desert, has attracted the attention of ecologists because of its declining population and wildfires. They began to think... Continue Reading →
During the Society for Integrative and Comparative Biology (SICB) 2024 conference, I interviewed Andrea Beverly and Jamie Lau, from Radford University, who are studying how the construction of the Mountain Valley Pipeline (MVP) is impacting freshwater streams in Rural Virginia. We discuss their collaboration with local groups, the intersection between politics and science, and the... Continue Reading →
A statue of a fox, as long as 16 meters with a height of over 10 meters, with a bag between its teeth sits in the middle of the Dutch city Rotterdam (Smets, 2024). It is locally known as the Bospoldervos, created by Hofman in 2020. Not without reason, because precisely in this part of... Continue Reading →
Think about a classic urban species. The first ones that come to mind are usually rats, pigeons and cockroaches. I’d bet that less than 10% of people reading this thought of a reptile. With cockroaches (and possibly ants) being the exception, most big names of the city are birds and mammals. Rats, mice, squirrels, (feral)... Continue Reading →
Did you know that it has been estimated that the anthropogenic mass, representing all human-made objects, would exceed the living biomass in 2020 ± 6 years? Each year, humans accumulate 30 Gigatons of anthropogenic mass, based on the averages of the last 5 years. The article that made these estimations even mentions that “this corresponds...

Urban environments consist mostly of bricks, concrete, asphalt, metal and glass: not very alluring substrates for many terrestrial organisms. Certain mosses and lichens can be seen sometimes on walls in the city, but even they will not easily grow in direct sunlight during dry periods, especially taking the ‘urban heat island effect’ into account (Deilami...

Next to the crucial trade route of the Panama canal sits Panama city, where an intriguing example of urban evolution has taken place. As Panama city has grown from a population of around 200,000 in the 1950’s to a population of around 2 million today, massive urbanization has taken place [1]. Urbanization is dramatically reshaping... Continue Reading →
Do you remember when was the last time you blew dandelion seeds? Do you remember the last time you stopped your busy schedule and noticed a dandelion blooming? As far as I can remember, I haven't done this since I was in primary school. Why are dandelions becoming more and more rare in big cities?... Continue Reading →
If I were to ask a typical citizen what comes to mind when they hear the word 'nature,' they would likely think of jungles, oceans, and forests. Logical, because when the media talks about how 'nature is declining' it usually refers to declining 'natural' habitats such as coral reefs, the Amazon Rainforest or the polar... Continue Reading →
Unfortunately, I missed something of which I think is one of the most fantastic natural phenomena the world has to offer. Instead of watching a wonderful dance of light in the sky, I was sleeping… It all happened last Friday night (10th of May 2024). One of the most wonderful natural phenomena was visible above...

Did you know that we are currently witnessing the largest extinction event on Earth in 250 million years? In this context, let’s delve into the crucial role of insects, even in our bustling cities. Contrary to what their small sizes might suggest, insects play a crucial role in our ecosystems. Without them, terrestrial and freshwater... Continue Reading →
The weather on the northern hemisphere is getting warmer which means beach days are approaching. Every beach dweller can confirm that seagulls (Larus sp.) can be very cunning and cheeky in order to steal food. Is this their ancestral behaviour or has this evolved with the rising of urban areas? Pavlova and Wronski (2020) studied... Continue Reading →
Around May, enormous swarms of termites wing up, coming out from the ground, trying to find the perfect match and establish their own families. After they find each other, the lovers shed their wings and seek out locations to build their marital homes, where they then reproduce. The nuptial flight of Macrotermes barneyi occurs every...
