Lurking beneath the trash laden leaf litter of the 5 boroughs lurks a secretive little amphibian that exemplifies the struggle between the forces of urbanization and the biological need to adapt or face extinction. The Eastern Red-backed Salamander (Plethodon cinereus) is a unique kind of caudate with numerous traits that make it well equipped to... Continue Reading →
New Lit Alert: Fine scale genetic structure in fire salamanders (Salamandra salamandra) along a rural‑to‑urban gradient
Fine scale genetic structure in fire salamanders (Salamandra salamandra) along a rural‑to‑urban gradient G. Yannic, V. Helfer, R. Sermier, B. R. Schmidt, L. Fumagalli Abstract Delineating population boundaries in anthropogenic landscape is of critical importance for domains of biology that are concerned with the ecology, evolution and conservation of species. This remains particularly difficult for species where there is... Continue Reading →
Urban Observation of the Week: Scaling Salamander
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 →
Urban Observation of the Week: Tough Urban Salamanders
Let's take a break this week from the urban birding realm. This week, we bring you marbled salamanders. Salamanders are usually found in wetlands, which are hard to come by inside cities. This is an awesome find! Do you have a photo or video of an urban species doing something unusual? What about a... Continue Reading →
A Tale of Two Amphibians: Urban Landscapes Differentially Impact Gene Flow
When we think of urban organisms, we often don't think of aquatic organisms. But wetlands exist in the urban matrix, and aquatic and amphibious species are impacted by habitat changes associated with urbanization. A recent study published in Ecology and Evolution by Jared Homola, Cynthia Loftin, and Michael Kinnison dug into the population genetics of... Continue Reading →
