Evolution in an Urbanizing World
Some fries left on the ground, a half-eaten sandwich, or some breadcrumbs kindly given by someone on a park bench. Pigeons (Columba livia) in the city don’t shy away from eating human-derived foods. Although most pigeons are eager to eat our food scraps, this behaviour has been linked to a likely downside: the urban lifestyle... Continue Reading →
Different traits shape winners and losers in urban bird assemblages across seasons Riccardo Alba, Fabio Marcolin, Giacomo Assandri, Luca Ilahiane, Francesca Cochis, Mattia Brambilla, Diego Rubolini & Dan Chamberlain Abstract Urbanisation is a major driver of global biodiversity decline, profoundly affecting animal communities. While most studies on bird communities have primarily focused on the breeding season, we aimed to identify species responses and... Continue Reading →
In the heart of the city, dominated by human-made material, animals face more than cars and concrete—they face humans. And to survive, some of them have developed a surprising skill: reading human behaviour and recognizing people. They learn who feeds them, who ignores them, and most importantly, who poses a threat to them. They need... Continue Reading →
Juan Diego Ibáñez-Álamo, Kaspar Delhey, Lucía Izquierdo, Mihai Valcu, Bart Kempenaers Juan Diego Ibáñez-Álamo and Kaspar Delhey shared first authors. Abstract Rapidly expanding urbanisation presents significant challenges to wildlife. Consequently, many studies have investigated the impact of urbanisation on diverse organisms. However, despite the ecological relevance of animal colouration, its association with urbanisation remains poorly understood. Using a global... Continue Reading →
“Dad, what are those birds? I’ve never seen them before” I remember asking my dad when I was younger. We were outside having a barbecue and for the first time, I noticed several green birds flying overhead accompanied by a cacophony of sounds. I had never seen or heard them before, but suddenly there they... Continue Reading →
Parallel Signatures of Diet Adaptation in the Invasive Common Myna Genome Kamolphat Atsawawaranunt, Katarina C. Stuart, Annabel Whibley, Kyle M. Ewart, Richard E. Major, Rebecca N. Johnson, Anna W. Santure Abstract Invasive species offer uniquely replicated model systems to study rapid adaptation. The common myna (Acridotheres tristis) has been introduced to over a dozen countries and is classified as one of... Continue Reading →
Coastal cities in Europe are swarmed with gulls, to the annoyance of many of those cities’ inhabitants. Gulls (Larus spp.) are naturally cliff-nesting species, but are able to thrive in urban areas because of the high food availability, the suitable climate, the similarity of nest substrate, lesser risk of predation and the presence of conspecifics...

In today’s urban environment, the constant presence of traffic noise is undeniable, infiltrating even the most hidden corners of the woods. Previous studies have shown that this anthropogenic noise negatively affects the welfare of both humans and other species. The fact that even unborn organisms experience negative effects is a worrying development, emphasizing the urgent... Continue Reading →
Have you ever seen a duck, goose, coot or any other waterbird laying long out on the ground or surface of the water? Do these birds look tired to you? If so, they might be suffering from botulism.Avian botulism, also known as Limberneck, is the most significant disease for migratory birds around the globe. Outbreaks... Continue Reading →
Urbanization is happening all over the world. Everywhere you look, you can see that cities are expanding and new cities are being built. This is often at the expense of nature. There is not a lot of room for vegetation in cities and more and more existing vegetation and farmlands are being turned into urban... Continue Reading →
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 →
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...

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 →
Knotted willows characterise many Dutch landscapes, where they are often seen in a row along creeks that have existed for decades. These willows are pruned every few years, which causes the characteristic wide “knot” at the treetop to form over time. Complex shapes can form due to this pruning, and it is quite common to...

[embedyt]https://www.youtube.com/watch?v=obHtOIJrwh8[/embedyt] Our perceptions of wildlife and nature are shaped by the media which highlights. The mold has been set by great figures like David Attenborough, with his memorable narrative voice. However, these documentaries only explored 'pristine' landscapes in far away lands, while ignoring the creatures that must contend with the Urban Jungle. In my first... Continue Reading →
