Evolution in an Urbanizing World
Danielle Sabin THE BACKGROUND When Splinter discovered four baby turtles in a New York City sewer, he had no idea what the glowing green goo was that covered their bodies. He simply cleaned them off and gave them a home. Shortly thereafter, these turtles grew very rapidly and mutated into anthropomorphic beings with proclivities for... Continue Reading →
As this tepid winter sweeps through NYC, a few careful eyes may spot a peculiar sight lounging in the mid-afternoon sun of our urban park spaces. Turtles, out and about in the middle of December! This Red-eared Slider (Trachemys scripta elegans) was found on December 9, 2022, at 2:06 pm; it was one of nearly... Continue Reading →
The growing field of urban evolutionary ecology studies the impact of urbanization on its resident species. Often, that involves comparisons between conspecific urban and non-urban populations. Jackson et al. took a different perspective in this study. They analyzed the divergence between populations living in adjacent but isolated city parks. They developed their study around a...

Natural and anthropogenic landscape factors shape functional connectivity of an ecological specialist in urban Southern California Sarah M. Wenner, Melanie A. Murphy, Kathleen S. Delaney, Gregory B. Pauly, Jonathan Q. Richmond, Robert N. Fisher, Jeanne M. Robertson Abstract Identifying how natural (i.e., unaltered by human activity) and anthropogenic landscape variables influence contemporary functional connectivity in... Continue Reading →
The annual Joint Meeting of Ichthyologists and Herpetologists is kicking off today and wow do I feel like I'm missing out! This year the conference has an impressive showing of urban research. Here's your guide for the week: Thursday 7/28 1:30pm — Boldness and behavioral syndromes across an urban gradient in the Brown Anole (Anolis sagrei) -... Continue Reading →
Morphological divergence, tail loss, and predation risk in urban lizards Shashank Balakrishna, Madhura Sham Amdekar & Maria Thaker Abstract Urbanisation changes the structure of natural habitats and alters trophic interactions, pressuring urban species to adjust and adapt. Unlike behavioural shifts that tend to be more flexible, morphological characteristics in vertebrates are less plastic and changes may come... Continue Reading →
From Anoles to Indian Agamids to Australian Water Dragons to Western Fence Lizards, lizards from diverse branches of the squamate tree are proving themselves in urban environments. Add one more species to this growing list of urban lizards: Brazilian lagartixas, Tropidurus hispidus. In a recent paper, Antonio de Andrade examined the abundance and habitat use of...

Did you know that all toads are frogs but not all frogs are toads? Frogs are found in and near water while true toads are found on land. This toad was found on a pile of trash, still on land though! Thanks to Julia Riley for this great urban observation. Julia was also a co-author... Continue Reading →
The annual Joint Meeting of Icthyologists and Herpetologists (JMIH) kicks off today in Snowbird, Utah. This is one of my favorite conferences so I'm sad I will not be attending this year. And unfortunately, none of our contributors are attending this meeting either this year (that I know of), so we will not be able... Continue Reading →
