Much recent attention has been focused on vegetative survival forms of planktonic diatoms and other algae. There are several reports of extended vegetative survival of the freshwater diatom Melosira in lake sediments. In contrast to those diatoms which form a morphologically distinct resistant spore, Melosira is known to produce physiological resting cells that are indistinguishable in outward morphology from actively growing cells.We used both light and electron microscopy to document and elucidate the sequence of cytological changes during the transition from resting cells to actively growing cells in a population of Melosira granulata from Douglas Lake, Michigan sediments collected in mid-July of 1983.

Ethical dilemmas encountered by psychologists have previously been studied in surveys and as formal ethical complaints. No previous publications have been found in which data from an ethics counseling telephone service for psychologists has been analyzed. The present study examines ethical dilemmas, as presented by members of the Norwegian Psychological Association calling the Ethics Telephone Counseling Service (ETCS) from 2001 through 2003. Psychologists seek counseling for a range of ethical dilemmas. Ethical dilemmas concerning confidentiality are those most commonly presented. Dilemmas concerning integrity are also fairly common, whereas dilemmas concerning competence are rarely presented. The study shows virtually no difference in frequency and nature of consultation based on how long a psychologist has been licensed. This study also shows only minor gender differences in the use of the ETCS. Possible implications for ethics education as a continuous process are discussed.
