New Lit Alert: Physiological and behavioral variation by urbanization and climate in an urban-tolerant toad

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 →

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 →

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: 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 →

New Lit Alert: Metabolic adjustment in urban birds: glycometabolic enzyme activities in urban and rural tree sparrows (passer montanus)

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 →

New Lit Alert: Variation in Pheidole nodus (Hymenoptera: Formicidae) functional morphology across urban parks

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 →

New Lit Alert: Do urban habitats induce physiological changes in Mediterranean lizards?

Do urban habitats induce physiological changes in Mediterranean lizards? R Vardi, S Dubiner, R Ben Bezalel, S Meiri, E Levin Abstract Urban environments offer dramatically different habitats for wildlife compared with natural environments. They provide, for example, different levels of resource availability, anthropogenic night light, and microclimates (e.g., urban heat islands). For reptiles, increased temperatures...
