Evolution in an Urbanizing World
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 →
As we know, the landscape of urban areas is changing rapidly as land is converted from natural to anthropogenic space. Additionally, new technology has allowed us to collect more data at a lower cost than ever before. The combination of these two events led my co-authors and me to ask "Are biologists keeping up with... Continue Reading →
Earlier this week, the wonderful women over at Women of Fisheries posted about the struggles of going to the bathroom when doing fieldwork on a boat. They point out that going to the bathroom can be especially uncomfortable for women since it's more difficult to easily pee off the side of the boat due to... Continue Reading →
For the past 1.5 years, we (the editors of LITC) have been working to bring together new empirical urban evolution research as well as novel reviews and perspectives. While this research has trickled out online over the past few months we're excited that it is officially published in Evolutionary Applications' first issue of 2021. This... Continue Reading →
Last year I had the pleasure of meeting Dr. Malle Carrasco-Harris at the International Urban Wildlife Conference (#IUWC2019). Carrasco-Harris has been studying the role urbanization plays in the behavior of Eastern Copperhead snakes (Agkistrodon contortrix) and while we might not think of snakes as congruent with cities, multiple species of snakes have been able to...

Urban areas around the world are an interesting combination of non-native and native species. In London, urban foxes are a common sight and because of this, we would predict that urban foxes have evolved due to differing selection factors in cities. For mammalogists, examing and comparing skulls is a common way to measure changes that... Continue Reading →
We often think about how the construction of new buildings, parking lots, and industrial areas will impact the local wildlife. And, indeed, governments require environmental impact surveys and ongoing monitoring when vulnerable species are present. However, it wasn't until I saw the paper "Music Festival Makes Hedgehogs Move: How Individuals Cope Behaviorally in Response to... Continue Reading →
Recently, Ruth Rivkin shared some of her dissertation work with the Canadian Society for Ecology and Evolution (CSEE). Urban habitats are more fragmented and degraded than nonurban habitats, which can impact both the ecology and evolution of species interactions. Species interaction may be particularly sensitive to urbanization because the species involved may be responding to... Continue Reading →
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 →
In light of recent events, particularly the murder of George Floyd, harassment of Christian Cooper, and unjust actions against protesters supporting the #BlackLivesMatter movement, we at LITC want to acknowledge the systematic oppression and racism that exists in our field. We wholeheartedly support the Black community and communities of color, and firmly stand against racism.... Continue Reading →
Urbanization is rapidly transforming the Earth leading to drastic changes in the local ecological communities and changing the evolutionary dynamics of organisms living within cities. Previous research has shown that urbanization can prohibit, facilitate, or have little effect on gene flow but the scale at which these phenomena occur are highly dependent on the organism,...

This week we are cross-posting from the Ecology & Evolution blog written by Dr. Emily Puckett and Elizabeth Carlen. Check out the original post here. Observations of numerous animal populations have documented morphometric changes in response to urbanization. Examples abound including: urban populations of anole lizards have longer limbs and more toe lamellae that aid in moving... Continue Reading →
Urban areas are known to be prone to habitat fragmentation. We've seen the intense urbanization in New York City lead to the rapid divergence of mouse populations and the subdivision of bobcats in Los Angeles. But the adverse effects of habitat fragmentation are difficult to quantify given that they differ based on the ability of... Continue Reading →
Urbanization can impact wildlife in different ways, depending on the organism and how it interacts with humans and the built environment. Geographical barriers may limit or prevent an organism from moving through a city and an organism's behavioral variability (particularly its ability to tolerate humans) may also influence if and how it disperses throughout a...

Milestones and more In 2019 we hit a lot of milestones. We turned 1 year old. We were featured in several major news outlets, including as a News Feature in PNAS, the Wildlife Society, and Wired Magazine! We reached over 13,000 visits since starting from (almost) every corner of the globe (we're looking at you,... Continue Reading →
