The activity pattern of Tegula funebralis - Howe, Mark W.
The activity pattern of the black turban snail, Tegula funebralis (A. Adams, 1854) at Pacific Grove, California, is the subject of this article. Field studies were carried out to follow the locomotory and feeding activities of individuals of T. funebralis, to determine how much of each animal's time was spent in each of these activities, and when and under what environmental conditions they occurred.
Time series analyses of biological and environmental variables for Suisun Bay and the Sacramento and San Joaquin rivers - Lehman, Peggy
EXTRACT (SEE PDF FOR FULL ABSTRACT):
Arima analysis was used to compute cross-correlations between principal component axes that described environmental variables, chlorophyll concentration and zooplankton density for the Sacramento and San Joaquin rivers and Suisun Bay. ... Cross-correlations among the time series may provide information about links between environmental and biological variables within the estuary and the possible influence of climate.
Toxicity of phenyl-mercuric lactate for fish - Ellis, M.M.
Phenyl-mercuric lactate is included in the pulp processing reagents by some paper mills to eliminate slime formation in the pulp. Small quantities of this chemical are added to the wet pulp in the beaters, particularly for the bactericidal action against Aerobacter aerogenes. Subsequently the mecurial is carried away in the wash waters. However, as the highly poisonous nature of many compounds of mercury is well known, questions have been raised concerning the pollution hazards created by phenyl-mercuric lactate in streams receiving effluents from mills using this substance.
Report on the biology of Pacific hagfish, Eptatretus stouti and the development of its fishery in California - Kato, Susumu
Hagfish, often referred to as "slime eels", are familiar to most fishermen as pests that frequently devour fish caught by trap, hook, and gillnet. In the Republic of Korea (ROK or South Korea), however, hagfish are sought after as valuable fish not only for their edible flesh, but also for their skin, which is processed into leather used to make expensive purses, shoes, and other articles. In fact, because of a shortage of hagfish in the waters near the ROK, the leather industry there has started to import hagfish, first from Japan in the mid 1980's, then from the United...
