1. Factors leading to differences in age of primiparity and possible life-history implications arising from these differences were studied in a population of Columbian ground squirrels (Spermophilus columbianus; Ord, 1815). We used data collecte[...]

1. We propose an alternative model to the host-shifting model of sympatric speciation in plant-insect systems. The role of competition in driving ecological adaptive radiation was evaluated in a seed predator exploiting a single host-plant speci[...]
