Evolution in an Urbanizing World
Amphibians can be really great "indicator species" that, if they are present and healthy, then the ecosystem is doing ok. Some amphibians though are really great generalists and can tolerate a range of ecosystem changes. This week, we see a two-lined salamander chomping on the bugs that the porch lights attract. Do you have a... Continue Reading →
Yesterday we shared some new research with you about the effects of light at night (ALAN) on anoles, featuring new research by contributor Chris Thawley. Today, we stick with that theme of activity at night and the night-light niche. In January (before I knew my fieldwork would be postponed indefinitely), I headed to the beautiful...

In the second of four urban anole presentations at Evolution, Emmanuel D'Agostino does a great job summarizing new research by LITC contributor Chris Thawley. Chris' post-doc research has really delved into the night-light niche and ALAN, a topic that is no stranger to this blog (check out: It’s Lit in the City, Is Artificial Light Changing Pigeon...

I live in New York City, “city that never sleeps,” where you can get a manicure at 11pm, a haircut at 1am, and a slice of pizza at 3am. While it may be normal for people to be out and about at all hours of the day, I was surprised when I was walking home,... Continue Reading →
Night life in the city can be much brighter and artificial lighting can be a significant source of new evolutionary directions for city dwellers. A recent study by Hopkins et al. (2018) researchers reviewed how Artificial Light At Night (ALAN) can drive evolutionary change in a theoretical population. How can artificial light at night (ALAN) drive evolution?...
