“…Moreover, soft-bottom macrofauna actively rework their habitat, changing the physical structure, layering and oxygen content of the sediment (Rhoads 1974). Certain deposit-feeding polychaete species transport copepod eggs upwards (Marcus & Schmidt-Gengenbach 1986), whereas the amphipod Monoporeia affinis (hereafter Monoporeia) has been considered to bury eggs in Baltic sediments (Albertsson & Leonardsson 2000). In addition to vertical movements, predation may also play a role, as benthic deposit-feeders may ingest dinoflagellate cysts (Persson & Rosenberg 2003), copepod eggs (Parker et al 1996) and ephippia (benthic eggs shielded by a transparent membrane) of daphnid cladocerans (Cáceres & Hairston 1998).…”

The effects of bioturbation and predation by the amphipod Monoporeia affinis, the bivalve Macoma balthica and the polychaetes Marenzelleria spp. were studied on the number, vertical distribution and hatching of benthic eggs (ephippia) of the cladoceran Bosmina longispina maritima. It was hypothesised that the 3 functionally different macrobenthic species affect Bosmina ephippia to different degrees. In addition, it was hypothesised that macrofaunal bioturbation either inhibits or enhances predation by the necto-benthic mysid Mysis mixta on cladoceran benthic eggs. M. affinis and M. balthica caused a 48 and 23% decrease in the total number of Bosmina ephippia, respectively, indicating egg predation. In addition, M. balthica extended the distribution of eggs into deeper sediment layers. Both M. affinis and M. balthica suppressed the daily hatching rate of Bosmina, and the effect of the bivalves (reduction 92%) was stronger than that of the amphipods (34 to 78%). None of the benthic species promoted the predation of mysids on Bosmina eggs. Instead, both M. affinis and M. balthica reduced the number of ephippia in the sediment surface (by 79 and 43%, respectively), implying that these species decrease the ability of mysids to feed on cladoceran benthic eggs. M. balthica was the most harmful species for the recruitment of Bosmina, whereas the nonindigenous Marenzelleria spp. did not affect ephippia.

“…As far as egg-bank functioning is concerned (egg hatching in relation to vertical distribution and sediment conditions), there is a complete absence of studies on fairy shrimps, in contrast to the ample literature existing for other crustacean orders (UYE et al, 1979;MARCUS, 1984;MARCUS and SCHMIDT GEGENBACH, 1986;MORITZ, 1987;HAIRSTON and DE STASIO, 1988;CARVALHO and WOLF, 1989;DE STASIO, 1989WOLF and CARVALHO, 1989;MARCUS et al, 1994;HAIRSTON et al, 1995;LAMPERT, 1995;BOERO et al, 1996;CACERES, 1997CACERES, , 1998CACERES and HAIRSTON, 1998;COUSYN and DE MEESTER, 1998;ROSSI et al, 1998 and b).…”

“…Another factor shown to have a substantial impact on egg bank structure and dynamics is bioturbation (KRANTZBERG, 1985;MARCUS and SCHMIDT GEGENBACH, 1986;MORITZ, 1987;CARVALHO and WOLF, 1989;KEARNS et al, 1996). Vertical transport of sediment and eggs may, in fact, play an important role in recruitment to the water column of resting eggs buried in sediments, in which they can be found as deep as 30 cm (HAIRSTON et al, 1995).…”

Structure and Functioning of the “Egg Bank” of a Fairy Shrimp in a Temporary Pool: Chirocephalus ruffoi from Pollino National Park (Southern Italy) as a Case Study

To investigate their distribution and total numbers, resting eggs of the anostracan Chirocephalus ruffoi were collected from the bed of a temporary pool in southern Italy. Samples were taken at 0.5 m intervals along six transects oriented at 30°from each other, by means of a cylindrical core sampler. The horizontal distribution of intact resting eggs was extremely patchy, with cyst number per core ranging from 191 to 1,400 (CV = 32.7%), corresponding to a mean of between 0.8 and 4.3 cysts cm -3 . Differences observed were related to core position and transect orientation, total cyst numbers being markedly higher in the leeward area of the pool compared to the windward area. Marked variation was also evident in vertical distribution, a significant, though weak correlation was recorded between egg density and sediment depth. Cyst-bank size (± 95% confidence limits) of the pool bed, estimated from the mean cyst number cm -3 obtained for the 6 transects, ranged between 1.0 × 10 8 and 1.3 × 10 8 cysts.Hatching in the laboratory was very erratic. Despite significant differences in hatching, the observed variation was unrelated to most of the variables considered (position within sections, cores and transects, pre-incubation treatment) and was explained only by initial sediment conditions (moist/dry). In none of the experimental conditions tested was synchronous hatching obtained.Possible causal factors (mixing of the bottom sediments by cattle, egg age, storage conditions, differential exposure to environmental cues as well as variability in hatching response even at clutch level) are discussed. IntroductionMany residents of temporary pools produce long-lived resting eggs enabling survival during unfavourable conditions. The changing nature of these habitats requires adaptation to very different environmental regimes. Moreover, the predictability and the frequency of the wet/dry phases vary greatly among habitats, depending on factors like climate, latitude, altitude, nature of the sediment etc. Therefore population persistence requires local adaptations in life history traits and, particularly in the hatching behaviour of the resting stages (BELK and COLE, 1975;WIGGINS et al., 1980). The more unpredictable the local habitat, the higher the risk of extinction favouring the evolution of adaptations that "spread the risk" (see review in SIMOVICH and HATHAWAY, 1997;BRENDONCK et al., 1998). Not all of the eggs deposited at one time will hatch during the same subsequent inundation and thus an egg bank (sensu DE STASIO, 1989) forms in the sediment, acting as a reserve for the future. In addition to information about quantitative reproductive characteristics, understanding the behaviour and functioning of an egg bank is of fundamental importance in identifying any local adaptations to habitat uncertainty.Internat.

Fubao Bay is located in the north of Lake Dianchi, which is one of the most seriously polluted bays in the lake. Two main rivers, Haihe River and Daqinghe River flow into Fubao Bay from the north. Four sampling sites were settled in this bay, and the sediment samples were collected by using Petersen grab. For the first time, the study of recruitment ability of Microcystis in different sediment environments was carried out in simulation devices. The results in the present study showed that the recruitment ability of Microcystis was quite different depended on its habitat environments. The Microcystis recovery was inhibited in lacustrine sediments near estuary, and the maximum biomass (calculated as chlorophyll-a) was pretty lower than other sampling sites. Compared among East Coast Area, West Coast Area and Hydraulic Mud Fill Area, the Microcystis biomass were only 4.7%, 6.6% and 11.9%, respectively. And Microcystis biomass (calculated as Microcystis cell numbers) were about 5.2%, 10.3% and 19.4%, corresponding.All the results indicated that sediments in estuary of Fubao Bay were not appropriate for Microcystis recruitment. The contribution of "seeds bank" recruiting to form HABs in this bay could be much less than the wind-induced external loading. All these results could be helpful in Microcystis blooms forecasting, preventing and controlling in the future.
