Blooming Phenology

The temporal patterning of flowering of five sympatric species of Pedicularis in a subalpine meadow is documented. Two species bloom early in the growing season, one is intermediate, and two flower toward the later part of the season. The differences between species are related to the range of blooming periods (in days), the number of inflorescences at maximum bloom, and the time of peak bloom. No significant variation in flowering pattern occurred during the years of observation (1977, 1978, and 1979). More than 93% of the time individual bumblebees continued to forage on the same Pedicularis species as was previously visited; yet when switches in the diet of the bees occurred, they were more likely to be to another species of Pedicularis. Although individuals of other genera were in bloom, the bees switched to the Pedicularis species most synchronous in time and space to the previously preferred Pedicularis species. Counts were made of the number of pollen grains per flower, the reward for foraging bees. The last species to flower had the greatest reward but also had the largest ratio of the number of pollen grains to the number of ovules as compared with the previously flowering Pedicularis species. These results suggest that pollinator sharing is an important evolutionary force but that the quantity of the pollen reward may be more related to the number of ovules.

Casual Observer

Two subalpine meadow communities near Mt. Baker, Washington, were inundated by a spill of 26 000 L of diesel oil in 1972. Studies were made of the initial impact of the oil on the vegetation and of community recovery over 9 years. Within two growing seasons following the spill, plant cover had decreased from a prespill cover of nearly 100% to 1% and all species except Phyllodoce empetriformis, Carex lenticularis, and Rhacomitrium sudeticum had died. Seedlings of Carex nigricans began to appear on bare soil after 1 year, followed by seedlings of other common subalpine species 2 to 4 years later. Nine years after the perturbation 5 to 20% of the ground was covered with vegetation and the original disturbance could no longer be discerned by a casual observer.
