“…While rapid germination was induced after 1 mo of storage at 22°C, dormancy was extended at 5°C (Anderson 1980). Comparable data on dinoflagellate dormancy are based on cyst germination conditioned to habitat temperatures: a 3 mo mandatory resting period was found for Gonyaulax digitale from the Woods Hole region (Wall & Dale 1968), and a 4 mo resting period for Alexandrium tamarense isolated from 90 m depth in the Gulf of Maine (Dale et al 1978). Therefore, ambient temperature is a major factor controlling the duration of the dormant period.…”

The seasonal occurrence of vegetative cells and cysts of the dinoflagellate Scrippsiella trochoidea in the water column was investigated in Yongil Bay (southeastern coast of Korea). To measure germination ratios of cysts, cysts were isolated monthly from natural sediment samples and incubated in the laboratory. Vegetative cell numbers peaked in June to July, when the surface water temperature increased to over 18°C. Mass encystments were detected in the water column in August 1996 and July 1997, when the vegetative population flourished. Active germination was observed during the period of decreasing water temperature in September and October, when the vegetative population declined. Thus, there was an opposing pattern of seasonality in the potential germination of cysts and the proliferation of vegetative cells, whereby decreases in one paralleled increases in the other. The dormant period of cysts was ca 60 d, far longer than reported previously. Germination ratios increased in October 1996 and September 1997 after a 2 mo dormancy period following the mass encystments. Germination appears to be flexible with respect with length of dormancy and the age composition of cysts, both of which are based on the time and the scale of encystments as well as on conditions in the benthic environment.

“…Resting spores are widely distributed among the free-living dinoflagellates, in autotrophic and heterotrophic, in thecate as well as in athecate representatives (Wall & Dale, 1968;Stosch, 1973;Dale, 1976). A proved occurrence in D. pseudolunula would represent the first record of resting spores in parasitic dinoflagellates.…”

“…Resting stages were recorded in crustaceans (Onbé, 1991;Mauchline, 1998), diatoms Hobson, 1995, 1996), dinoflagellates (Wall and Dale, 1968;Bolch and Hallegraeff, 1990;Sonneman and Hill, 1997;Nehring, 1997) and tintinnids (Reid and John, 1978;Kamiyama, 1996).…”

SUMMARY:The presence of resting stages in neritic areas is well known, while their occurrence in the deep sea realm has seldom been considered. Recent investigations showed strict interactions between neritic and deep sea domains, due to upand down-welling phenomena driven by submarine canyons. To estimate the presence of resting stages in deep bottom sediments, seven sediment cores, collected along a trans-Mediterranean transect by means a multi-corer during the TRANSMED survey (1999), were studied. Most biogenic sediment was composed of Foraminifera tests (tens of thousand tests cm -3 ), Calciodinellum albatrosianum and Leonella granifera (Dinophyta) cysts (up to thousands cysts cm -3 ). Eleven dinocyst morphotypes were recorded mainly as empty shells (seven calcareous-walled: C. albatrosianum, Calciperidinium asymmetricum, Leonella granifera, Scrippsiella trochoidea, S. precaria type 1, S. precaria type 2, S. regalis; four organicwalled: Impagidinium aculeatum, unid. dinocyst 1, unid. dinocyst 2 and unid. dinocyst 3), while no metazoan resting eggs were observed. The presence of viable resting stages in deep bottom surface sediments was much lower than in neritic areas, suggesting that oceanic species do not produce cysts for a "benthic resting" strategy. Further taxonomic and biogeographic studies are needed to better understand the ecological dynamics of oceanic plankton in the Mediterranean Sea.Key words: resting stages, deep sea, Mediterranean, biogenic sediments, cyst morphology. RESUMEN: ABUNDANCIA DE ESTADIOS QUIESCENTES EN LA FRACCIÓN BIOGÉNICA DE SEDIMENTOS SUPERFICIALES DEL MAR MEDITERRÁNEO PROFUNDO. -La presencia de estadios quiescentes en áreas neríticas es bien conocida, pero su presencia en fondos profundos raramente se considera. Investigaciones recientes han demostrado interacciones estrictas entre los ámbi-tos nerítico y profundo, debido a fenómenos de afloramiento y hundimiento mediados por los cañones submarinos. Para estimar la presencia de estadios quiescentes en sedimentos profundos se estudiaron siete testigos de sedimento, obtenidos durante el proyecto TRANSMED a lo largo de un transecto transmediterráneo. utilizando un tomatestigos múltiple. La mayor parte de sedimento biogénico estaba compuesto por caparazones de foraminíferos (decenas de miles de caparazones cm -3 ), cistes de Calciodinellum albatrosianum y Leonella granifera (Dinófitos; hasta miles de cistes cm -3 ). Se registraron once morfotipos de dinocistes principalmente como caparazones vacíos (siete con paredes calcáreas: C. albatrosianum, Calciperidinium asymmetricum, Leonella granifera, Scrippsiella trochoidea, S. precaria tipo 1, S. precaria tipo 2, S. regalis; cuatro con paredes orgánicas: Impagidinium aculeatum, dinociste no identificado 1, dinociste no id. 2 y dinociste no id. 3), mientras que no se observaron huevos de reposo de metazoos. La presencia de estadios quiescentes viables en sedimentos superficiales profundos fue mucho menor que en áreas neríticas, lo que sugiere que las especies oceánicas no producen ciste...
