Caption: A spotted salamander (Ambystoma maculatum) migrates to a roadside pond. Roadside spotted salamanders have joined the ranks of many species showing locally adaptive responses to human modified habitats. Specifically, sotted salamanders maintain survival advantages in their polluted natal ponds compared to nearby conspecifics transplanted there, Credits: Steven Brady; 3. Caption: A mating pair of the common bluetail damselfly (Ischnura elegans): male above and female below. Females in this species experience intense male mating harassment, which leads to frequency‐dependent sexual conflict that maintains a female genetic colour polymorphism, with consequences for population fitness and persistence. One of the three female colour morph is male‐coloured (so‐called androchrome females), and such a female morph is shown in this picture, Credits: Erik Svensson; 4. Caption: A group of roosters (Gallus gallus) from a large, feral population on the island of Key West, Credits: N/A; 5. Caption: Marked resident female from the studied population of Ram Mountain, Alberta, in 2015. As for all resident sheep on the mountain, this female has been closely monitored and captured every year since birth, Credits: Marc‐Antoine Poirier; 6. Caption: Daphnia thermal evolution is hindered by rapid evolution of their algal resource to warming, Credits: Michelle Tseng.
