Evolution in an Urbanizing World
A number of years ago there was quite a lot of media attention regarding a possible case of in situ evolution of Culex pipiens form molestus in the London Underground metro system. This media buzz created speculation that this was a unique species that had risen during the over 160 year long existence of the... Continue Reading →

Domestic Cats (Felis silvestris catus; Felis catus) are a human commensal, said to have started their relationship with us during the era of the first settled farmers (approx. 12.000 years ago) within the Fertile Crescent region of the middle east.1 We took them into our homes and slowly transformed them into the royalty that a lot...

As urbanization continues to reshape landscapes, its effects on wildlife have become a subject of growing concern. In the unique context of Cuba, a recent study focused on an endemic lizard species, Anolis homolechis, found in both natural and suburban environments. This in-depth study relied on adapted tracking methods deployed over several years and explored... Continue Reading →
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 (and... Continue Reading →
Who would ever have expected to see plovers on the banks of the Huangpu River in Shanghai? The Huangpu River is the "mother river" of Shanghai that flows north throughout Shanghai. It passes some of the most population-dense regions of the city, including Lujiazui and the Bund, and provides green paths on both banks for... Continue Reading →
By Veerle Langezaal During the Covid-19 lockdowns, a grassroots movement emerged where botanists in France, the UK, and the Netherlands began chalking plant species names on sidewalks. This initiative aimed to educate communities about the ecological importance of these plants, challenging the perception of them as mere weeds. This movement has since evolved into a...

Native to the Indian subcontinent and the southern fringes of the Sahel, the ring-necked parakeet (Psittacula krameri) looks wonderfully out of place in the cities of Western Europe. How and when exactly the colourful bird species established itself in isolated pockets so far from its naturally occurring range is heavily disputed, and subject to many... Continue Reading →
Do urban habitats induce physiological changes in Mediterranean lizards? R Vardi, S Dubiner, R Ben Bezalel, S Meiri, E Levin Abstract Urban environments offer dramatically different habitats for wildlife compared with natural environments. They provide, for example, different levels of resource availability, anthropogenic night light, and microclimates (e.g., urban heat islands). For reptiles, increased temperatures...

The City Nature Challenge is an annual competition among hundreds of international cities to increase awareness of urban biodiversity. Last year’s challenge totaled 1,694,877 observations, 50,176+ species, and 67,220 participants across 450+ cities worldwide. Check if your city is participating in this year’s challenge! If not, join the global project this year and sign-up your city to participate in 2024’s challenge! This year’s challenge is active starting tomorrow, April 28, to... Continue Reading →
Going Wild in the City--Animal Feralization and Its Impact on Biodiversity in Urban Environments T Göttert, G Perry Abstract Domestication describes a range of changes to wild species as they are increasingly brought under human selection and husbandry. Feralization is the process whereby a species leaves the human sphere and undergoes increasing natural selection in... Continue Reading →

The growing field of urban evolutionary ecology studies the impact of urbanization on its resident species. Often, that involves comparisons between conspecific urban and non-urban populations. Jackson et al. took a different perspective in this study. They analyzed the divergence between populations living in adjacent but isolated city parks. They developed their study around a...
