How does urbanization affect natural selection? Anne Charmantier, Tracy Burkhard, Laura Gervais, Charles Perrier, Albrecht I. Schulte-Hostedde & Megan J. Thompson Abstract Urbanisation is one of the most significant contributors to the Anthropocene, and urban evolutionary ecology has become an important field of research. While it is commonly assumed that cities impose new and/or stronger... Continue Reading →
New Lit Alert: Urban Life Affects Differentiation and Phenotypic Variation but not Asymmetry in a Fully Terrestrial Salamander
Urban Life Affects Differentiation and Phenotypic Variation but not Asymmetry in a Fully Terrestrial Salamander Lucía Alarcón-Ríos, Antigoni Kaliontzopoulou, David Álvarez & Guillermo Velo-Antón Abstract The environmental transformations associated with cities are expected to affect organisms at the demographic, phenotypic, and evolutionary level, often negatively. The prompt detection of stressed populations before their viability is compromised is essential to... Continue Reading →
The rise of Culex molestus: True Urban Evolution or a mere eco-type?
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 →
Vintage nests: Birds turning trash into treasures
Sadly, plastics and litter have become part of the urban and often rural environment. It can be found almost everywhere and in any form – ranging from plastic bags to broken traffic cones. We consider it trash, however, for some birds, it is a jackpot. Often, litter is creatively included during nest building by these... Continue Reading →
Urban Environments – A Hidden Insect Biodiversity Hotspot?
Walid-Dani Kaki “In none of his works did Nature show her originality more than in insects”(Pliny the Elder) In recent years we have seen a steady decline in biodiversity, with devastating consequences for the natural world and human populations. The tendency of people to migrate to urban areas has led to their chaotic development at... Continue Reading →
How the GLUE Animation Came About
“How life adapts to cities around the world” is a 5 minute educational animated film created by Sherry An (myself), a science and medical illuHow the GLUE Animation Came Aboutstrator and designer from Mississauga, Canada. The film uses 3D animation and visual storytelling to share the goals and results of the first GLUE study in... Continue Reading →
New Lit Alert: Fast-paced city life? Tempo and mode of phenotypic changes in urban birds from Switzerland
Fast-paced city life? Tempo and mode of phenotypic changes in urban birds from Switzerland Evelyn Hüppi & Madeleine Geiger Abstract Humans' large influence on the environment has constructed many new ecological niches, such as in urban areas. Phenotypic changes, including morphological ones related to human influence, are known from a small number of bird species.... Continue Reading →
New Lit Alert: A Theory of City Biogeography and the Origin of Urban Species

Martin, Jason Munshi-South, Lauren M. Nichols, Edward L. Vargo, Senay Yitbarek, Yuhao Zhao and Angélica Cibrián-Jaramillo Abstract Many of the choices humans make with regard to infrastructure, urban planning... Continue Reading →
New Book Alert: Chasing Bats and Tracking Rats Urban Ecology, Community Science, and How We Share Our Cities
A new urban ecology book by Dr. Cylita Guy is out that highlights the work of multiple urban ecologists and evolutionary biologists, including many of our LITC contributors! What can city bees tell us about climate change? How are we changing coyote behavior? And what the heck is a science bike? Featuring the work of... Continue Reading →
New Lit Alert: Genetic differentiation in pesticide resistance between urban and rural populations of a nontarget freshwater keystone interactor, Daphnia magna
Genetic differentiation in pesticide resistance between urban and rural populations of a nontarget freshwater keystone interactor, Daphnia magna Kristien I. Brans, Rafaela A. Almeida, Maxime Fajgenblat Abstract There is growing evidence that urbanization drives adaptive evolution in response to thermal gradients. One such example is documented in the water flea Daphnia magna. However, organisms residing in urban lentic... Continue Reading →
Urban Evolution & Art
The piece below was posted in 2018 by A.Z. Andis Arietta a PhD candidate in the School of Forestry & Environmental Studies at Yale University -- I recently rediscovered it and thought it would be of interest to our followers. Check out Andis's blog here. In schools, we are taught that evolution is an imperceptibly... Continue Reading →
Cities and Behavioral Adaptations
It's clear that urbanization alters native animal and plant communities around the world. However, while some organisms become locally extinct as anthropogenic forces change the land, other species survive or even thrive in this urban landscape. A recent paper by George Perry reviews several cases of human behavior impacting the genetics of urban organisms. For... Continue Reading →
Conserving Urban Biodiversity Needs an Evolutionary Mindset
A variety of species – animals, plants, fungi, microbes – share our cities with us. Some we love, some we hate, and some we hardly notice. Some of these species existed naturally before we built cities. Some were obliterated during urban construction but have since re-entered the city. And others have been purposefully or accidentally... Continue Reading →
