Evolution in an Urbanizing World
When thinking about a city at night, chances are that you include some twinkling streetlights in your mental image. Billboards, streetlamps, and neon signs are no novel presence to city dwellers. These light sources are in technical terms called artificial lights at night, or ALAN for short. While thinking about a city at night can... Continue Reading →
In the heart of the city, dominated by human-made material, animals face more than cars and concrete—they face humans. And to survive, some of them have developed a surprising skill: reading human behaviour and recognizing people. They learn who feeds them, who ignores them, and most importantly, who poses a threat to them. They need... Continue Reading →
Increasing artificial light In recent decades, the urban population has grown exponentially worldwide, with the expectation that the urban population will continue to increase the next decades. As cities expand, so does the reliance on artificial light sources to illuminate the night. This increases the visibility for humans when it is dark, but it can... Continue Reading →
As urbanization continues to reshape landscapes, its effects on wildlife have become a subject of growing concern. In the unique context of Cuba, a recent study focused on an endemic lizard species, Anolis homolechis, found in both natural and suburban environments. This in-depth study relied on adapted tracking methods deployed over several years and explored... Continue Reading →
[embedyt]https://www.youtube.com/watch?v=obHtOIJrwh8[/embedyt] Our perceptions of wildlife and nature are shaped by the media which highlights. The mold has been set by great figures like David Attenborough, with his memorable narrative voice. However, these documentaries only explored 'pristine' landscapes in far away lands, while ignoring the creatures that must contend with the Urban Jungle. In my first... Continue Reading →
Skyscrapers as Ecological Traps of the Spotted Lanternfly (Lycorma delicatula) (Hemiptera: Fulgoridae): Preliminary Observations Kenneth D. Frank & Gregory W. Cowper Abstract Since its introduction to North America from Asia in 2014, the spotted lanternfly has emerged as a pest in rural and suburban settings. In downtown Philadelphia we found adults of the spotted lanternfly... Continue Reading →
While I was out birding on Governor's Island, My friends and I came across this old traffic cone. It stood out to me as a sore thumb, a bright red monolith in a lawn of green grass. My curiosity led me to peek inside, and lo and behold! There was a Common House Spider (Parasteatoda... Continue Reading →
“There are ecologists in urban areas, and then there are urban ecologists” - Dr. Chris Schell This point made by my advisor (Dr. Christopher Schell) creates a clear distinction that there are urban ecologists who do not fully integrate social processes (nor the full human, e.g., perceptions, culture) in their studies. And there are urban... Continue Reading →
Urban ecology, although a burgeoning field, is becoming massive. In this field, there is much to think about when developing a question investigating the effect of “urbanization” on a particular species. Even within “urbanization” (which most urban ecologists recognize as just semantics and not a clear definition), there are many quantifications for this (see Moll... Continue Reading →
Connectivity in the Urban Landscape (2015–2020): Who? Where? What? When? Why? and How? Todd R. Lookingbill, Emily S. Minor, Charles S. Mullis, Gabriela C. Nunez-Mir & Philip Johnson Abstract Purpose of Review This review uses a combination of narrative and systematic review techniques, including automated content analysis (ACA), to summarize the last 5 years of research...

The European Starling Sturnus vulgaris Ever had such a fondness for an author, that you wanted to recreate what they wrote, in real life? That’s exactly what Eugene Schieffelin did with the European Starling in Central Park, NYC, when he decided to introduce as many of the birds mentioned in Shakespeare’s works to North America...

Monk parakeets Myiopsitta monachus Sometimes referred to as the Quaker parrot due to their quaking vocalizations, the monk parakeet is a small, green parrot with grey breast and head feathers accented with blue feathers on their primaries. In addition to their unique color, these birds can often be picked out by their noisy/screechy vocalizations.... Continue Reading →
This new feature on the blog will focus on urban introduced species across the globe, giving brief histories of where they came from, how they got where they are now & more on their ecology and evolution. The Gold Dust Day Gecko Phelsuma laticauda Best known for the starring role as the “Geico” gecko, the... Continue Reading →
In August 2020, I recently published my first first-author paper about urban Anolis lizard claws! I have previously written about my research after doing field work and presenting at my university's science symposium. I'm excited to report that the results are finally out! In our paper, The Finer Points of Urban Adaptation, myself and my coauthors (Kevin... Continue Reading →
A recent paper in Scientific Reports, "Of city and village mice" by Dammhahn et al (2020), investigated the behavioral responses of striped field mice (Apodemus agrarius) to urbanization. The ability for an animal to adjust their behavior to a novel environment can contribute to survival in urban habitats, with the possibility of local adaptation to... Continue Reading →
