The seasonal succession of plankton is an annually repeated process community assembly during which all major external factors and internal interactions shaping communities can be studied. A quarter a century ago, the state this understanding was described by verbal ecology group (PEG) model. It emphasized role physical factors, grazing nutrient limitation for phytoplankton, food fish predation zooplankton. Although originally targeted at lake ecosystems, it also adopted marine ecologists....
Background Regime shifts are abrupt changes encompassing a multitude of physical properties and ecosystem variables, which lead to new regime conditions. Recent investigations focus on the in diversity functioning associated such shifts. Of particular interest, because implication climate drivers, that occur synchronously separated basins. Principal Findings In this work we analyze review long-term records Mediterranean ecological hydro-climate variables find all point synchronous change...
Climate variability across three distinct spatial scales and the interannual changes of planktonic copepods jellyfish were studied from November 1966 to December 1993. The results obtained identified a cascade links between large-scale climate pattern playing out in North Atlantic local governing Ligurian Sea, northwestern Mediterranean. chain events appeared driven by long-term temperature anomalies that turn played key role relationship jellyfish. Indeed, increase outbreaks during 1980s...
Abstract In marine ecosystems, pelagic copepods, chaetognaths and jellyfish play a key role in matter energy flow. While copepods support most food webs the biological pump of carbon into deep ocean, may affect strength top‐down control upon plankton communities. this study, we show that main events long‐term variability these functional groups Northwestern Mediterranean were tightly linked to changes climate forcing North Atlantic sector. Large‐scale has altered food‐web dynamics through...
We analyzed the seasonal variations of ctenophore Mnemiopsis leidyi weekly collected since its first record in western Baltic Sea October 2006. The distribution pattern together with dynamics and population outbreaks late summer 2007 indicate recent successfully establishment M. this area. Seasonal changes showed two periods high reproductive activity characterized by a structure dominated small size classes, followed an increase larger ones. These results further revealed that bulk remains...
The sudden occurrence of the ctenophore Mnemiopsis leidyi has been reported recently from different regions Baltic Sea and it suggested that species invaded whole basin. Here we provide first set quantitative data seasonal diet composition life history traits M. its predatory role in pelagic ecosystem Western Sea. size structure appeared to be dominated by small classes only a few adults were as large those native region other areas. We show high preference for small-sized slow swimming...
We investigated potential connections between climate and the population size of gelatinous carnivores in northwestern Mediterranean. The interannual variability large‐ meso‐scale factors was related to carnivore dynamics by means a multivariate regression model. Gelatinous integrate climate‐related changes Mediterranean with close correlations Calycophoran siphonophores Chelophyes appendiculata Abylopsis tetragona Hydromedusae Rhopalonema velatum Solmundella bitentaculata . show that...
Abstract Aim Global anthropogenic changes have altered biogeography and phenology of marine populations, thereby promoting a spatial reconfiguration in the functioning ecosystems. Among these changes, massive proliferations jellyfish temperate latitudes warn potential alterations biogeochemical fluxes, ecosystems’ structure assets, services they provide to human welfare. Understanding driving factors shaping large‐scale patterns is pressing need global ecology sustainability science. Using...
Lake Geneva is a deep, peri-alpine lake where there has been continuous monitoring program since the 1970s. The long suffered from eutrophication. In early 1980s, restoration plan resulted in progressive reduction phosphorus concentration. During same period, responded to large-scale climate changes by overall warming of water, and timing stratification. Both composition phenology plankton have affected. This paper focuses on long-term observed copepod community. Our findings highlight...
We explore the attenuation in export ratio of jelly‐POM (particulate organic matter) with depth as a function decay rate, temperature, and sedimentation rate. Using data from Vertical Transport In Global Ocean project, we compare ratios computed Martin‐curve, particle‐based parameterization, sediment‐trap data. Owing to temperature dependence rate ( Q 10 = 4.28), below 500 m is 20–45% larger subpolar temperate areas than tropics. migration gelatinous zooplankton leads variable starting jelly...
Abstract Fernández de Puelles, M. L., and Molinero, J. C. 2008. Decadal changes in hydrographic ecological time-series the Balearic Sea (western Mediterranean), identifying links between climate zooplankton. – ICES Journal of Marine Science, 65: 311–317. We investigated possible relationships climate, hydrography, zooplankton abundance (BS), during a 10-year survey period spanning January 1994 to December 2003. It was demonstrated that large-scale atmospheric variability North Atlantic (NA)...
Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate these organisms may have on local populations, biodiversity, ultimately functioning food webs. In Mediterranean Sea, little known about dynamics jellyfish, although this area a biodiversity hotspot one most threatened by an increasing number jellyfish. Here, we investigated population non-indigenous scyphomedusa, Aurelia solida Browne 1905, in Bizerte Lagoon, Tunisia. The study was...
The rising demand of ecosystem services, due to the increasing human population in coastal areas, and subsequent need secure healthy sustainable seas constitute a major challenge for marine ecosystems management. In addition, global anthropogenic changes have transformed realm, thereby challenging health services necessary welfare. These opened ecological space opportunistic organisms, such as jellyfish, resulting ecosystem-wide economic implications that threaten services. Here, we used...
We assessed interrelations between climatic, meteorological and hydrological factors in the Balearic Sea, identified drivers of abundance variability planktonic copepods over period 1994–2003. Temporal total appears to be indicative southern spreading Northern Current, therefore meridional transport water masses Sea. The results show that large‐scale atmospheric North Atlantic Ocean acts as a main driver regional variations hydrographic patterns Sea area. clearly most novel insight from this...
