Disappearance of the cascades frog Rana cascadae at the southern end of its range, California, USA Disappearance of the cascades frog Rana cascadae at the southern end of its range, California, USA
It has recently become evident that amphibian species in many areas of the world have suffered serious declines. Healthy, seemingly well-protected populations have disappeared for no obvious reason. Data from historic accounts and museum records indicate that the Cascades frog, Rana cascadae, was once abundant at the southern end of its range in the vicinity of Lassen Volcanic National...

Recruitment of seedlings and vegetative sprouts in unburned chaparral Recruitment of seedlings and vegetative sprouts in unburned chaparral
Age structure of 12 stands of chaparral, unburned for 56—120 yr, was investigated. All shrubs produced discernible growth rings, and ring counts on stems from stands of known age, plus synchrony in annual growth ring width among species in the same stand, were taken as evidence that growth rings represented annual rings. Species that survive fire by vegetative regeneration from the root...

Associations between benthic flora and diel changes in dissolved arsenic, phosphorus, and related physico-chemical parameters Associations between benthic flora and diel changes in dissolved arsenic, phosphorus, and related physico-chemical parameters
Diel relationships between physical and chemical parameters and biomass were examined along a 57-km reach of Whitewood Creek, South Dakota, between 29 August and 2 September 1988. A time lag of ∼3-6 h for fluctuations in soluble reactive phosphorus (SRP) concentrations (ranging from 0.1 to 0.5 μM at the downstream sites) relative to dissolved arsenic (ranging from 0.3 to 1.2 μM as...
