“…A complete study of an ecological phenomenon such as DVM should include a proximate and an ultimate aspect (Ringelberg & Van Gool 2003). The proximate aspect must answer questions on how animals migrate and what physiological and behavioural mechanisms are involved in migration.…”

“…The ultimate aspect must answer why migrations occur, and what adaptive significance can be attributed to the phenomenon. Such an approach is, however, not simply realised, and confusion of proximate and ultimate aspects easily occurs in practice (Ringelberg & Van Gool 2003). Four proximate factors are considered the most important in this respect: light changes, fish presence, food concentration, and temperature.…”

Diel vertical distribution patterns of dominant zooplankton taxa were studied during a period of midnight sun (May 1999) in the Marginal Ice Zone (MIZ) of the Barents Sea along 2 transects across the ice edge. Eight stations were sampled every 6 h over 24 h at 5 depth intervals. Our study confirmed that copepod nauplii (most probably Calanus hyperboreus and C. glacialis) together with Pseudocalanus spp. preferred the surface water layer. The herbivores C. finmarchicus, C. glacialis, and C. hyperboreus concentrated in the upper 50 m depth interval, whereas the omnivores Metridia longa and Microcalanus spp. were generally found in deeper waters. As a result of vertical distribution patterns of the numerically abundant taxa, a bulk of zooplankton was concentrated within the 0-50 m layer. Vertical distribution patterns of all examined taxa/groups varied in time as a result of habitat changes (with respect to water mass distribution and sea depth) as well as random patchiness. Based on our data and on a comprehensive literature survey on Arctic zooplankton diel vertical migration (DVM), we postulate that common zooplankton taxa in the MIZ of the Barents Sea do not perform DVM under the midnight sun. Arctic C. glacialis in May 1999 occupied deeper layers at stations with more ice cover and less melt water. This distribution pattern was probably related to the species' reproduction. At the same time, Atlantic C. finmarchicus was concentrated further away from the ice edge and chlorophyll a maximum, and presumably had not begun its seasonal reproduction.

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.

“…It has been found that diel fluctuation of plankton is guided by a number of physico-chemical parameters and biological components of an aquatic system (Lampert, 1993;Melo andHuszar, 2000, Pinilla, 2006). The light has been considered as the most important factor triggering the diel vertical migration of plankton (Ringelberg and Van Gool, 2003). However, other environmental factors such as temperature (Haney, 1993), dissolved oxygen (Hanazato and Yasuno, 1989;Horpilla et al, 2000) and availability of food (Leibold, 1990) are also involved in regulating such behaviours of plankton.…”

Diurnal fluctuation of the phytoplankton and zooplankton population (numerical densities) and the physicochemical attributes of water are studied in an aquaculture pond at Guwahati, Assam. In the 24 hour diel cycle, the phytoplankton and zooplankton show significant (t-test, p < 0.01) variation in their numerical density at an interval of 4 hours. The studied physico-chemical parameters of water included Temperature, Total Alkalinity (TA), Total hardness (TH), Dissolved Oxygen (DO), Free Carbon dioxide (FCO 2 ) and pH are analyzed concurrently, which reveals a significant fluctuation (t-test, p< .01) in the day and night hours. Multivariate correlation analysis portrays significant and positive correlations among the total population density of phytoplankton with respect to water temperature (r = 0.845, p<0.05) and pH (r = 0.881, p< 0.01) while it maintains significant negative correlations with TA (r = -0.837, p< 0.05), TH (r = -0.768, p< 0.05) and FCO 2 (r = -0.830, p<0.05). However, total numerical density of zooplankton reveals positive and significant correlations with TA (r = 0.842, p< 0.05) and FCO 2 (r= 0.758, p< 0.05) while it shows significant negative correlations with water temperature (r = -0.906, p< 0.01) and pH (r =-0.912, p< 0.01).
