Malic acid accumulation in roots in response to flooding: Evidence contrary to its role as an alternative to ethanol Malic acid accumulation in roots in response to flooding: Evidence contrary to its role as an alternative to ethanol
Across a time course of flooding the malic acid content in roots of the swamp tree Nyssa sylvatica var. biflora increased 5-fold from 1 week to 1 month of flooding and remained at that level through a full year of flooding. Alcoholic fermentation rates accelerated within the first month of flooding but dropped to very low levels under long-term flooding. The theory that, under flooding...

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...

Seed production, seed populations in the soil and seedling production after fire for two congeneric pairs of sprouting and nonsprouting chaparral shrubs Seed production, seed populations in the soil and seedling production after fire for two congeneric pairs of sprouting and nonsprouting chaparral shrubs
A study of seed production, seed storage in the soil, and seedling production after fire was undertaken for a sprouting and a nonsprouting congenerica pair of species of Ceanothus and Arctostaphylos. All species exhibited large fluctuations in annual seed production. There was a significant correlation between fruit production and precipitation in the previous year. It is hypothesized...

Sterility among female lizards (Uta stansburiana) exposed to continuous gamma irradiation Sterility among female lizards (Uta stansburiana) exposed to continuous gamma irradiation
A natural population of the lizard Uta stansburiana occupying a fenced 9-ha area in southern Nevada was exposed to essentially continuous γ irradiation from an artificial source between February 1964 and September 1973. Tissue doses were estimated using implanted lithium fluoride microdosimeters. Females became sterile as early as 11 months of age, but many were still fertile at ages of...
