Aim: Viviparity has evolved more times in squamates than in any other vertebrate group. Therefore, squamates offer an excellent model system to study the patterns, drivers, and implications of reproductive mode evolution. Based on current species distributions we examined three selective forces hypothesized to drive squamate viviparity evolution: (1) cold climate, (2) variable climate, and (3) hypoxic conditions, and tested whether viviparity is associated with larger body size. Location: Global. Time period: present day. Taxon:...

Data from: Climate change is associated with increased allocation to potential outcrossing in a common mixed mating species

Matthew Austin, Piper Cole, Kenneth Olsen & Adam Smith
Premise: The balance between cross- and self-fertilization is driven by the environment. Yet no long-term study has documented whether anthropogenic climate change is affecting reproductive strategy allocation in species with mixed mating systems. Here, we test whether the common blue violet (Viola sororia; Violaceae) has altered relative allocation to the production of potentially outcrossing flowers as the climate has changed across the 20th century. Methods: Using herbarium records spanning 1875 to 2015 from the central...
