The annual meeting of the Society for Integrative and Comparative Biology (SICB) is here! From January 3-7 biologists will convene in Atlanta, Georgia to share the latest and greatest from a broad range of research areas. Urban evolution talks have a strong showing at the meeting this year, and we would like to hear about all of... Continue Reading →
City lights, moonlit nights: examining bat responses to urbanization and lunar cycles Claysson de Aguiar Silva & Ludmilla M. S. Aguiar Abstract Urbanization is one of the most abrupt mechanisms of land use change. This process can generate significant impacts on biodiversity, and its effects on bat activity patterns need further exploration due to the importance... Continue Reading →
Body size and survival of urban and rural populations of a common wolf spider are not influenced by lifelong exposure to lead pollution Lucy Guarnieri, Leo Taylor, P. Larry Phelan & Mary Margaret Gardiner Abstract Heavy metal pollution is pervasive in urban soils, and it can negatively impact the fitness of arthropods. Arthropod populations can evolve to...

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,...

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 →
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 →
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 →
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 →
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 →
