Power and speed of swimming dolphins Power and speed of swimming dolphins
The belief that dolphins have an extraordinary ability to generate propulsive power or can modify the water flow over their bodies to the low-resistance laminar flow is pervasive in the perception of the animals by the public and by some of the biology communities. I analyzed measured swimming speeds for dolphins of the Stenella-Delphinus morphology. A conservative hydrodynamics model...

Ten years of change in seed banks of the chaparral shrubs, Arctostaphylos glauca and A. glandulosa Ten years of change in seed banks of the chaparral shrubs, Arctostaphylos glauca and A. glandulosa
In 1 decade, more than 107 seeds/ha were dispersed by two species of Arctostaphylos in a stand of chaparral. At the end of this decade no significant change in the size of the soil seed bank was detected for either species. Previous studies suggest that predation by ground-dwelling rodents limits the accumulation of seeds in the soil.

Mortalities of kelp-forest fishes associated with large oceanic waves off central California, 1982-1983 Mortalities of kelp-forest fishes associated with large oceanic waves off central California, 1982-1983
Observations of three incidents of the mass mortality of nearshore fishes are reported; each corresponded to periods of high-amplitude, long-period swells during the 1982-1983 El Niño event along the coast of central California. Members of the nearshore kelp forest fish assemblage, primarily of the genus Sebastes, accounted for 96% of the observed mortalities and S. mystinus (blue...

Stochastic model for the long-term transport of stored sediment in a river channel Stochastic model for the long-term transport of stored sediment in a river channel
We develop a stochastic model for the transport of stored sediment down a river channel. The model is based on probabilities of transition of particles among four different sediment storage reservoirs, called active (often mobilized), semiactive, inactive, and stable (hardly ever mobilized). The probabilities are derived from computed sediment residence times. Two aspects of sediment...
