Evolution in an Urbanizing World
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 →
Urbanization is a global form of habitat change that alters native habits and either excludes the animals that live there or forces them to acclimate to novel environments. Altering behavioral strategies can allow individuals to quickly acclimate and successfully colonize urban habitats, reproduce and live within them. In two studies presented at SICB, researchers, Dr.... Continue Reading →
Urban environments are on the rise, bringing with them pollutants from run-off which alters water temperature, chemistry, and hydrology, ultimately driving a decrease in biodiversity. These disturbances can affect the physiological stress response of fishes by increasing or dysregulating their primary stress hormone, cortisol, and potentially altering their reproductive allocation. Arseniy Kolonin, a master’s student at Texas State... Continue Reading →
A painted lady (Vanessa cardui), a species of butterfly common in urban habitats (Photo credit: Jean-Pol GRANDMONT) The urban heat island effect is a well-known consequence of urbanization whereby temperatures in cities are higher than those in surrounding natural areas. One wrinkle in the heat island effect is that the increase in temperatures is not... Continue Reading →
Urbanization has repeatedly been shown to negatively impact wild animals and is a particular concern for wild birds. Fortunately, some species are able to flexibly alter their behavioral phenotypes and adapt to the busy life in the city. Resource competition may be higher in urban environments, thereby selecting for more aggressive behaviors in city-slicking birds.... Continue Reading →
Have you ever stopped to look at the city lights at night? Have you ever wondered what impact these lights have on wildlife? Chris Thawley, Zach Forsburg, and Krystie Miner all asked this question in their research on artificial light at night, or ALAN. After exploring how ALAN, affected anoles in a laboratory setting,...

With this gorgeous Tampa weather, the last thing anyone at SICB 2019 wants to think about is snow and ice. Everyone except for Megan Kobiela, a PhD candidate from University of Minnesota, who studies the effects of deicing salt on monarch butterflies. By using salt to keep roads safe in the winter, humans have dramatically... Continue Reading →
What consequences does the urban heat island effect have for animals that live in cities? How might increased heat interact with other environmental factors, such as water availability, to affect survival or fitness of animals exposed to these higher temperatures? Dustin Johnson, a masters student in Zach Stahlschmidt’s lab at University of the Pacific chose... Continue Reading →
The annual meeting of the Society for Integrative and Comparative Biology (SICB) is almost here! From January 3-7 biologists will convene in Tampa, Florida to share the latest and greatest from a broad range of research areas. Urban evolution talks have a strong showing at the meeting this year, and we would like to hear... Continue Reading →
