Evolution in an Urbanizing World
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 →
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 (and... 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 →
Cryptic eco-evolutionary feedback in the city: Urban evolution of prey dampens the effect of urban evolution of the predator Kristien I. Brans, Nedim Tüzün, Arnaud Sentis, Luc De Meester, Robby Stoks Abstract Most research on eco-evolutionary feedbacks focuses on ecological consequences of evolution in a single species. This ignores the fact that evolution in response... Continue Reading →
Unexpected dispersal of Australian brush-turkeys (Alectura lathami) in an urban landscape MATTHEW J. HALL, JOHN M. MARTIN, ALICIA L. BURNS, AND DIETER F. HOCHULI Abstract Australian brush-turkeys (Alectura lathami) are atypical urban colonising birds due to their poor flight and dispersal ability, ground foraging and nesting behaviour, and lack of parental care for their chicks....

In a previous post titled Meta-analysis of Urban Bird Phenology, we discussed how urban conditions have affected the average value of phenology and reproductive phenotypes in bird species. Capilla-Lasheras et al. found that urban bird populations had lower values than their non-urban conspecifics for three life-history traits, indicating earlier lay dates, smaller clutch sizes, and...

Activity patterns and behavior of Myocastor coypus in a gated community in the metropolitan area of Buenos Aires (Argentina) Magdalena Salas, Julio C Hernandez-Hernandez, Martín Iglesias, María J Corriale Abstract Anthropization processes confront local wildlife with a new set of conditions that may lead to local extinctions or allow the expansion of some species. This... Continue Reading →
A global meta-analysis reveals higher variation in breeding phenology in urban birds than in their non-urban neighbours Pablo Capilla-Lasheras, Megan J. Thompson, Alfredo Sánchez-Tójar, Yacob Haddou, Claire J. Branston, Denis Réale, Anne Charmantier, Davide M. Dominoni Abstract Cities pose a major ecological challenge for wildlife worldwide. Phenotypic variation, which can result from underlying genetic variation... Continue Reading →
Rock Refuges Are Strongly Associated with Increased Urban Occupancy in the Western Fence Lizard, Sceloporus occidentalis Alexander J. Rurik, Seth C. Wilmoth, Kendra E. Dayton and Amanda M. Sparkman Abstract Urbanization has dramatically altered habitats for local species worldwide. While some species are unable to meet the challenges that these alterations bring, others are able to...

Temperature and not landscape composition shapes wild bee communities in an urban environment Costanza Geppert, Andree Cappellari, Daria Corcos, Valerio Caruso, Pierfilippo Cerretti, Maurizio Mei, Lorenzo Marini Abstract 1. More than half of the world’s population lives in urban areas, a proportion that is expected to increase. Even if urbanisation is widely regarded as a... Continue Reading →
