Physiological and behavioral variation by urbanization and climate in an urban-tolerant toad Dillon J. Monroe, Veronika Bókony & Caitlin R. Gabor Abstract The distribution of a species is best understood by examining the organism-environment interaction. Climate and anthropogenic habitat degradation, including urbanization, are salient features of the environment that can limit species distributions, especially for... Continue Reading →
An Urban Fairy-Tale: Saving Butterflies from Urbanization
Cities are expanding and the world has become increasingly urbanised in recent decades. Urbanization is a main driver of global biodiversity loss and insect declines due to loss and fragmentation of habitats and reduction of the quality of remaining habitat patches (1–3). Butterflies are often the focus of urban biodiversity studies and used as indicator... Continue Reading →
How do we make birds feel more at home?
Taking a walk through the busy streets of the city, life appears to be all around us. Bikers briskly pass you by, drivers honk loudly and hundreds of people walk around as if you find yourself in an anthill. A pigeon quickly takes off before a food-courier rushes past. A sea gull tries to snatch... Continue Reading →
New Lit Alert: Signatures of local adaptation and maladaptation to future climate in wild Zizania latifolia
Signatures of local adaptation and maladaptation to future climate in wild Zizania latifolia Yang Zou, Weidong Yang, Ruxue Zhang & Xinwei Xu Abstract Global climate change poses challenges to agricultural production and food security. Assessing the adaptive capacity of crop wild relatives to future climate is important for protecting key germplasm resources and breeding new crops. We performed population genomics,...

New Lit Alert: Big cities, big bodies: urbanisation correlates with large body sizes and enhanced body condition in African dwarf chameleons (Genus: Bradypodion)
Big cities, big bodies: urbanisation correlates with large body sizes and enhanced body condition in African dwarf chameleons (Genus: Bradypodion) Jody M. Barends & Krystal A. Tolley Abstract Urbanisation is a major driver of habitat transformation that alters the environmental conditions and selective regimes of the habitats where it occurs. For species inhabiting urban habitats, such... Continue Reading →
Algae might be the cure to pharmaceutical waste
With the rise of modern medicine came the rise of pharmaceutical waste. Not only expired or discontinued drugs and hospital waste fall under this category, but also sources such as the components of ingested drugs that are not being metabolized by the patient, therefore reaches their faeces, which are disposed of in the bathroom and...

New Lit Alert: Continent-wide parallel urban evolution of increased heat tolerance in a common moth
Continent-wide parallel urban evolution of increased heat tolerance in a common moth Thomas Merckx, Matthew E. Nielsen, Tuomas Kankaanpää, Tomáš Kadlec, Mahtab Yazdanian, Sami M. Kivelä Abstract Urbanization and its urban-heat-island effect (UHI) have expanding footprints worldwide. The UHI means that urban habitats experience a higher mean and more frequent extreme high temperatures than rural... Continue Reading →
New Lit Alert: How does urbanization affect natural selection?
How does urbanization affect natural selection? Anne Charmantier, Tracy Burkhard, Laura Gervais, Charles Perrier, Albrecht I. Schulte-Hostedde & Megan J. Thompson Abstract Urbanisation is one of the most significant contributors to the Anthropocene, and urban evolutionary ecology has become an important field of research. While it is commonly assumed that cities impose new and/or stronger... Continue Reading →
Navigating towards a quieter urban environment: mitigating the threat of traffic noise
In today’s urban environment, the constant presence of traffic noise is undeniable, infiltrating even the most hidden corners of the woods. Previous studies have shown that this anthropogenic noise negatively affects the welfare of both humans and other species. The fact that even unborn organisms experience negative effects is a worrying development, emphasizing the urgent... Continue Reading →
New Lit Alert: Urban Life Affects Differentiation and Phenotypic Variation but not Asymmetry in a Fully Terrestrial Salamander
Urban Life Affects Differentiation and Phenotypic Variation but not Asymmetry in a Fully Terrestrial Salamander Lucía Alarcón-Ríos, Antigoni Kaliontzopoulou, David Álvarez & Guillermo Velo-Antón Abstract The environmental transformations associated with cities are expected to affect organisms at the demographic, phenotypic, and evolutionary level, often negatively. The prompt detection of stressed populations before their viability is compromised is essential to... Continue Reading →
The rise of Culex molestus: True Urban Evolution or a mere eco-type?
A number of years ago there was quite a lot of media attention regarding a possible case of in situ evolution of Culex pipiens form molestus in the London Underground metro system. This media buzz created speculation that this was a unique species that had risen during the over 160 year long existence of the... Continue Reading →
Why the long neck? Signs of avian botulism to look out for!

If so, they might be suffering from botulism.Avian botulism, also known as Limberneck, is the most significant disease for migratory birds around the globe. Outbreaks... Continue Reading →
Of leopards and men; the presence of a lethal predator in Mumbai
Darkness sets over India’s largest city. Of course, a city with a population exceeding 12 million people will never be truly dark. Or silent. Still, in those neighborhoods bordering Sanjay Gandhi National Park the vibrant city center feels far away. In this park the wild part of India is still visible as the densely vegetated...

Focus points for urban biodiversity conservation planning and design for birds, reptiles and amphibians
Urbanization is happening all over the world. Everywhere you look, you can see that cities are expanding and new cities are being built. This is often at the expense of nature. There is not a lot of room for vegetation in cities and more and more existing vegetation and farmlands are being turned into urban... Continue Reading →
