Evaluation of an aerial survey of Pacific walruses Evaluation of an aerial survey of Pacific walruses
An aerial survey of Pacific walruses (Odobenus rosmarus divergens) was evaluated to determine the reliability of estimates of population abundance. The probability of detecting groups of walruses on the pack ice remained uniform to at least 0.93 km from the flight line, whereas the probability of detection decreased significantly beyond 0.23 km for walruses in the water. Walruses were...

Sea otter predation and community organization in the western Aleutian Island, Alaska Sea otter predation and community organization in the western Aleutian Island, Alaska
Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition. Sea urchins are larger...

Reproduction of chaparral shrubs after fire: A comparison of sprouting and seeding strategies Reproduction of chaparral shrubs after fire: A comparison of sprouting and seeding strategies
The relative ability of sprouting and nonsprouting chaparral shrubs to recover from fire was studied by examining population of congeneric pairs of species in burned and adjacent unburned areas. The pairs of species selected, with the nonsprouting species named first, were Arctostaphylos glauca - A. glandulosa and Ceanothus greggii - C. leucodermis. Data were also obtained on certain...
