Evolution in an Urbanizing World
Although many urban residents are woefully familiar with flies (Order: Diptera), I am willing to bet not many know about the Peacock Fly (Callopistromyia annulipes). A native of North America, this diminutive fly stands out from the rest of its kin due to its rather peculiar behavior, seen below! This otherwise cryptically-colored fly uses its...

Urban environment determines population genetics in the green toad, Bufotes viridis Viktória Vargová, Damiána Gužiová, Monika Balogová, Natália Pipová, Marcel Uhrin & Peter Kaňuch Abstract Heavily urbanized areas can hinder dispersal and gene flow between amphibian populations. Given the growth potential of urbanization, it is important to examine how this specific environment shapes their genetic... 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 →
Metabolic adjustment in urban birds: glycometabolic enzyme activities in urban and rural tree sparrows (passer montanus) J Shang, S Cun, S Zhang, W Liang Abstract Urbanization is rapidly changing habitats of wild birds around the world. Food availability is one of the important factors leading to phenotypic differences between urban and rural bird populations. Comparing... Continue Reading →
Variation in Pheidole nodus (Hymenoptera: Formicidae) functional morphology across urban parks Y Luo, QM Wei, C Newman, XQ Huang, XY Luo, ZM Zhou Abstract Background Habitat fragmentation and consequent population isolation in urban areas can impose significant selection pressures on individuals and species confined to urban islands, such as parks. Despite many comparative studies on... Continue Reading →

The groundhog (Marmota monax) is a very widespread North American species. Their range... Continue Reading →
Habitat Use, Terrestriality and Feeding Behaviour of Javan Slow Lorises in Urban Areas of a Multi-Use Landscape in Indonesia L Karimloo, M Campera, M.A. Imron, S Rakholia, A Mehta, K Hedger, K.A.I. Nekaris Abstract Urban areas are rapidly expanding into natural habitats worldwide. When species are threatened with habitat loss, it is vital to understand... Continue Reading →
The New York Canid Project is a community science study led by Isabella Vinces, a Science research student at Ossining High School. The goal for this study is to determine the effects of coyote populations on previously residing red fox populations in urban and suburban areas throughout New York. To participate, you simply have to... Continue Reading →
By Veerle Langezaal During the Covid-19 lockdowns, a grassroots movement emerged where botanists in France, the UK, and the Netherlands began chalking plant species names on sidewalks. This initiative aimed to educate communities about the ecological importance of these plants, challenging the perception of them as mere weeds. This movement has since evolved into a...

The Asian Ladybeetle (Harmonia axyridis) is a common sight in many urban gardens, such as those on Governor's Island in New York Harbor. They are voracious predators, feeding on soft-bodied arthropods like aphids and scale insects. These beetles were imported into the united states in 1916 to help control insect pests. Larval Asian Lady beetle... Continue Reading →
Native to the Indian subcontinent and the southern fringes of the Sahel, the ring-necked parakeet (Psittacula krameri) looks wonderfully out of place in the cities of Western Europe. How and when exactly the colourful bird species established itself in isolated pockets so far from its naturally occurring range is heavily disputed, and subject to many... Continue Reading →
Sadly, plastics and litter have become part of the urban and often rural environment. It can be found almost everywhere and in any form – ranging from plastic bags to broken traffic cones. We consider it trash, however, for some birds, it is a jackpot. Often, litter is creatively included during nest building by these... Continue Reading →
The influence of road networks on brown bear spatial distribution and habitat suitability in a human-modified landscape E Gonzalez-Bernardo, MDM Delgado, DGG Matos, A Zarzo-Arias, A Morales-Gonzalez, H Ruiz-Villar, M Skuban, L Maiorano, P Ciucci, J Balbontin, V Penteriani Abstract Roads are human infrastructure that heavily affect wildlife, often with marked impacts on carnivores, including...

Guest post by Brandon Waldo, Katherine Moore, Sam Bickley, Christopher Anderson, & Moises Bernal. Salinity, Urbanization, and Genetic Divergence of Killifish Coastlines are unique and dynamic environments that are always subject to intense changes. Organisms living in beaches, estuaries, and marshes constantly face fluctuations in water conditions that can alter their habitat, making hardiness and... Continue Reading →
