Evolution in an Urbanizing World
The ongoing global urban expansion presents resident wildlife with many changes to their environmental structure. A few changes created by anthropogenic growth include habitat fragmentation, roads and buildings, pollution, and increased human presence. These consequences of urbanization have caused many species to become locally extinct, while others appear to thrive from the effects of urban... Continue Reading →
Cities offer an unprecedented global experiment for parallel evolutionary change: they similarly differ in several dimensions including climate, land cover, and pollution. Yet few studies examine evolutionary change across multiple cities, which is critical for identifying environmental characteristics that mediate adaptive responses. For example, city size, age, and habitat connectivity may all contribute to the... Continue Reading →
My eyes are instinctively drawn to a black, blue, and snow white flurry of movement. A reflex hammer to my naturalist’s knee. The subject of my fascination springs a brisk two-footed hop-scotch, just ahead along a ribbon of green separating parking lot from bustling sidewalk in downtown Calgary.
