“…Finally, the rate of decrease in light intensity initiates upward swimming. As has been shown in a number of studies (e.g., Ringelberg, 1964Ringelberg, , 1991Forward and Hettler, 1992;Cohen and Forward, 2005a, b), the relative rates of decrease in light intensity that evoke an ascent response correspond to rates observed at sunset (reviewed by Cohen and Forward, 2009). …”

“…Since the underwater spectrum at twilight matches the spectrum in air regardless of water type, the spectral sensitivity of R. harrisii is, in fact, matched to the spectrum in its environment at the time of vertical migration. Interestingly, all other species of zooplankton have the same major spectral sensitivity maximum around 500 nm Cohen and Forward, 2009), and in fishes the visual pigments that are used for dim light vision (scotopic pigment) are also around 500 nm (e.g., Munz and McFarland, 1973;Hobson et al, 1981;Crescitelli et al, 1985).…”

“…Although the isolume hypothesis for DVM of zooplankton was proposed almost a century ago (Ewald, 1910;Rose, 1925;Russell, 1927), field evidence is rare. Recent studies show that the day depth of zooplankton can be associated with an isolume (reviewed by Cohen and Forward, 2009) and zooplankton can change their day depth with changes in the depth of isolumes (e.g., Frank and Widder, 2002). However, observations that zooplankton actually vertically migrate with an isolume are confined to studies of migrations of sonic scattering layers (Boden andKampa, 1967), of krill (Onsrun andKaartvedt, 1988), and of R. harrisii zoea Cronin and Forward, 1986).…”

“…An important recent advance in the study of DVM is the recognition that the behavior is a phenotypic response activated by chemical cues (kairomones) from predatory fishes (reviewed by Cohen and Forward, 2009). A laboratory approach for documenting predator-induced phenotypic plasticity in DVM is to observe the behavior of zooplankton to light cues that are involved in DVM in the presence of odor cues from fish (e.g., Ringelberg, 1991).…”

Abstract. This synthesis reviews the physiological ecology and behavior of larvae of the benthic crab Rhithropanopeus harrisii, which occurs in low-salinity areas of estuaries. Larvae are released rhythmically around the time of high tide in tidal estuaries and in the 2-h interval after sunset in nontidal estuaries. As in most subtidal crustaceans, the timing of larval release is controlled by the developing embryos, which release peptide pheromones that stimulate larval release behavior by the female to synchronize the time of egg hatching. Larvae pass through four zoeal stages and a postlarval or megalopal stage that are planktonic before metamorphosis. They are retained near the adult population by means of an endogenous tidal rhythm in vertical migration. Larvae have several safeguards against predation: they undergo nocturnal diel vertical migration (DVM) and have a shadow response to avoid encountering predators, and they bear long spines as a deterrent. Photoresponses during DVM and the shadow response are enhanced by exposure to chemical cues from the mucus of predator fishes and ctenophores. The primary visual pigment has a spectral sensitivity maximum at about 500 nm, which is typical for zooplankton and matches the ambient spectrum at twilight. Larvae can detect vertical gradients in temperature, salinity, and hydrostatic pressure, which are used for depth regulation and avoidance of adverse environmental conditions. Characteristics that are related to the larval habitat and are common to other crab larval species are considered.

“…Although the latter two patterns are rare for invertebrate larvae (Young and Chia, 1987;Queiroga and Blanton, 2005), some larvae, particularly decapods, are sensitive to the diel light cycle (Forward et al, 1984). These behaviours occur in a wide range of planktonic animals and are considered to be predator avoidance behaviour because larvae alter their DVM patterns in the presence of predators (Bollens and Frost, 1991;Neill, 1992;Cohen and Forward, 2009).…”

Abe, H., Sato-Okoshi, W., Nishitani, G. and Endo, Y. 2014. Vertical distribution and migration of planktonic polychaete larvae in Onagawa Bay, north-eastern Japan. Memoirs of Museum Victoria 71: 1-9.The planktonic larvae of polychaetes are one of the most numerous and diverse groups in coastal zooplankton; however, little is known about their larval dynamics and the factors that affect their vertical distribution. We investigated the vertical distribution and migration of planktonic polychaete larvae in Onagawa Bay, north-eastern Japan, particularly focusing on the dominant spionid larvae. In total, 14 families of planktonic polychaete larvae and 14 species or genera of spionid larvae were identified during our study. Their density greatly fluctuated according to season and depth, with the polychaete larvae generally distributed in the lower layers of the water column. Furthermore, trends in vertical distribution of spionid larvae varied between species. In winter and spring, larvae of Polydora onagawaensis were the most prevalent, with a wide range in vertical distribution. In summer and autumn, larvae of Pseudopolydora achaeta and Prionospio spp. were the most prevalent spionid larvae and were primarily distributed in the lower layers of the water column. Trends in larval vertical distribution varied as a result of differences in adult habitat; these variations would enable the larvae to efficiently recruit into their appropriate adult habitats. Spionid larvae did not show diel vertical migration. Larvae of two spionid taxa, Pseudopolydora achaeta and Prionospio spp., exhibited tidal vertical migration, with larvae appearing to avoid dispersal by moving to slower-flowing deeper water during flood and ebb tides. Although many previous studies assume that, because of their limited swimming capacity, polychaete larvae are passively dispersed within the water column, this study indicates that polychaete larvae can control their vertical distribution to some extent, and this smallscale vertical migration may be important as a retention mechanism for polychaete larvae.

Day–night cycle is the main zeitgeber (time giver) for biological circadian rhythms. Recently, it was suggested that natural diurnal geomagnetic variation may also be utilized by organisms for the synchronization of these rhythms. In this study, life‐history traits in Daphnia magna were evaluated after short‐term and multigenerational exposure to 16 h day/8 h night cycle, 32 h day/16 h night cycle, diurnal geomagnetic variation of 24 h, simulated magnetic variation of 48 h, and combinations of these conditions. With short‐term exposure, the lighting mode substantially influenced the brood to brood period and the lifespan in daphnids. The brood to brood period, brood size, and body length of crustaceans similarly depended on the lighting mode during the multigenerational exposure. At the same time, an interaction of lighting mode and magnetic variations affected to a lesser extent brood to brood period, brood size, and newborn's body length. The influence of simulated diurnal variation on life‐history traits in daphnids appeared distinctly as effects of synchronization between periods of lighting mode and magnetic variations during the multigenerational exposure. Newborn's body length significantly depended on the lighting regime when the periods of both studied zeitgebers were unsynchronized, or on the interaction of light regime with magnetic variations when the periods were synchronized. These results confirm the hypothesis that diurnal geomagnetic variation is an additional zeitgeber for biological circadian rhythms. Possible mechanisms for these observed effects are discussed.
