Evolution in an Urbanizing World
When people consider the causes of the decline in bird or small mammal populations most will first think of pesticides or vehicle deaths. However, one of the biggest threats to these birds and mammals may actually be our own dear pet cats. Domestic cats (Felis catus) contribute significantly to the decline in urban wildlife. Cats...

Our typical urban rats, mainly brown rats (Rattus norvegicus), have undergone adaptations that enable them to thrive in urban environments. These adaptations distinguish urban rats from their wild relatives and highlight the impact of urbanization on species evolution. Genetic evolution and neighborhood adaptations In cities like New York City (NYC), with a rat population estimated... Continue Reading →
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 →
Juan Diego Ibáñez-Álamo, Kaspar Delhey, Lucía Izquierdo, Mihai Valcu, Bart Kempenaers Juan Diego Ibáñez-Álamo and Kaspar Delhey shared first authors. Abstract Rapidly expanding urbanisation presents significant challenges to wildlife. Consequently, many studies have investigated the impact of urbanisation on diverse organisms. However, despite the ecological relevance of animal colouration, its association with urbanisation remains poorly understood. Using a global... Continue Reading →
In urban ecology, a lot of attention has been paid to groups such as birds and trees and how they adapt to life in the human hive, but an often-neglected group are the lichens. These easily overlooked species are developing in their own way in the human dominated urban habitat. All lichens are a symbiotic... Continue Reading →
“Dad, what are those birds? I’ve never seen them before” I remember asking my dad when I was younger. We were outside having a barbecue and for the first time, I noticed several green birds flying overhead accompanied by a cacophony of sounds. I had never seen or heard them before, but suddenly there they... Continue Reading →
Domestic Cats (Felis silvestris catus; Felis catus) are a human commensal, said to have started their relationship with us during the era of the first settled farmers (approx. 12.000 years ago) within the Fertile Crescent region of the middle east.1 We took them into our homes and slowly transformed them into the royalty that a lot...

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 →
In response to human impact on the environment—from increased light, sound, air, and water pollution, to higher levels of interaction with humans—organisms must adapt to novel conditions in order to survive. One area in which organisms adapt is behavior. von Merton et. al. (2022) explores how the behavior and personality of two shrew species (Crocidura... Continue Reading →
Walid-Dani Kaki “In none of his works did Nature show her originality more than in insects”(Pliny the Elder) In recent years we have seen a steady decline in biodiversity, with devastating consequences for the natural world and human populations. The tendency of people to migrate to urban areas has led to their chaotic development at... Continue Reading →
Influence of habitat type and distance from source area on bird taxonomic and functional diversity in a Neotropical megacity Marcos Antônio Melo, Patrícia Mara Sanches, Demóstenes F. Silva Filho & Augusto João Piratelli Abstract The Neotropical region has been subjected to massive urbanization, which poses high risks for some global biodiversity hotspots and losses of...

While huddled up in a nook on my apartment's rooftop, camera set up and aimed at the skies above, I briefly witnessed a skirmish between a Red-tailed Hawk (Buteo jamaicensis) and a Peregrine Falcon (Falco peregrinus). I was able to document the interaction above my head with the featured image above. I feel so honored... 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 →
