Evolution in an Urbanizing World
A recent article published in Conservation Genetics by Gizelle Hurtado and Karen Mabry found that even low levels of urbanization can influence genetic structure of Merriam's kangaroo rat. Researchers collected the kangaroo rats from Las Cruces, NM in 5 urban and 5 non-urban sites to compare genetic diversity and genetic structure between the two habitat... Continue Reading →
For those of you who follow us and live in the Greater Toronto Area (GTA), I'm giving a talk at the Riverwood Conservancy this Saturday, April 20th at 9:30 am. You can register for the event here. I will be talking about how urbanization can influence evolution for a lot of different organisms, including plants... Continue Reading →
The annual Evolution meeting co-sponsored by the Society for the Study of Evolution, Society of Systematic Biologists, and American Society of Naturalists is coming soon to Providence, Rhode Island this June 21-25th! This meeting usually has a strong representation of researchers working in urban systems and we hope this year will be no different. Are... Continue Reading →
An outstanding question in urban evolutionary biology is what factors influence a species' success in urban environments. This is a topic we've talked about before (check out Urban Adaptation in Mammals) and several other recent papers have tackled this topic. A variety of factors may influence whether or not a species occupies an urban environment... Continue Reading →
What is urbanization and how do we, as urban evolutionary biologists, ecologists, and conservation biologists, define this metric? We've written about this topic before and a new paper by Remington Moll et al. titled "What does urbanization actually mean? A framework for urban metrics in wildlife research" takes a deep dive into defining urbanization. Generally,... Continue Reading →
Evidence for evolution in urban systems is increasing, but a key outstanding question in the field of urban ecology and eco-evolutionary dynamics is whether the ability of individuals to adapt to environmental conditions (plasticity) also evolves and how this process can happen. In a new paper, Sarah Diamond and her collaborators looked to examine the... Continue Reading →
This is part two of a two part series from Carly Ziter and Karen Dyson, adapted from a recent paper we wrote as a “how to” guide to urban fieldwork on private land. In last week's post Fieldwork on Urban Private Property: Getting Started, we talked about how to get started with fieldwork on urban private... Continue Reading →
Let’s consider a scenario. You’re designing a new research project, and you realize that for the first time that you (or your students) are going to need access to private property in an urban area to answer your question properly. Do you need a permit? A permission form? Who do you ask? Should you just... Continue Reading →
Coyote have widely colonized every mayor city in the United States. A new study asks what behaviors urban coyotes exhibit and what this might tells us about the process facilitating their success in the city.
What does it mean to be urbanized on a volcanic archipelago? With ‘Darwin Day’ (February 12th) just behind us, my upcoming research trip to the Galápagos Islands feels almost unbelievably well-timed. My goal will be to study one of the fabled Darwin’s finches, the small ground finch (Geospiza fuliginosa), and its relationship with an invasive... Continue Reading →
Mammals are some of the most easily recognizable and endearing critters to share our cities with us. Who doesn't love a cute bunny or squirrel in a city park? Or a fox or raccoon slinking through the streets at night. Even city rats can be endearing. Despite the commonality of these species, urban areas are... Continue Reading →
Anole invasion One of my favorite things about Florida, besides the warm weather, is that it's home to several anole lizards that have invaded from nearby. Some lizards invaders come from Cuba, like the brown anole (Anolis sagrei). Others, like the crested anole (Anolis cristatellus) come from Puerto Rico (like me!). This makes Florida a fascinating...

As someone studying animals in cities, I often feel need to justify why it is essential that we understand how organisms utilize and evolve within urban habitat. People may think that I study urban environments because I’m lazy or can’t handle real fieldwork, but the truth is that we know very little about how animal... Continue Reading →
Above: (c) Erin Walsh for Journal of Conservation Physiology on the evolution of heat tolerance in Daphnia Earlier this week, I introduced you to the aquatic flea, Daphnia magna, and its habitat in urban environments. I'll pick up where I left off and tell you now about the research I've been doing with these aquatic organisms. After... Continue Reading →
