“…The scyphozoan jellyWsh Aurelia aurita (L.) was selected for the study as it is ubiquitous at temperate latitudes (Russell 1970;Lucas 2001) and has been previously considered in numerous studies of marine food webs (e.g. Lynam et al 2005;Malej et al 2007;Purcell et al 2010).…”

JellyWsh are increasingly topical within studies of marine food webs. Stable isotope analysis represents a valuable technique to unravel the complex trophic role of these long-overlooked species. In other taxa, sample preservation has been shown to alter the isotopic values of species under consideration, potentially leading to misinterpretation of trophic ecology. To identify potential preservation eVects in jellyWsh, we collected Aurelia aurita from Strangford Lough (54 o 22Ј44.73ЉN, 5 o 32Ј53.44ЉW) during May 2009 and processed them using three diVerent methods prior to isotopic analysis (unpreserved, frozen and preserved in ethanol). A distinct preservation eVect was found on 15 N values: furthermore, preservation also inXuenced the positive allometric relationship between individual size and 15 N values. Conversely, 13 C values remained consistent between the three preservation methods, conXicting with previous Wndings for other invertebrate, Wsh and mammalian species. These Wndings have implications for incorporation of jellyWsh into marine food webs and remote sampling regimes where preservation of samples is unavoidable.

“…It has been suggested that environmental variation affects the abundance and distribution of jellyfish medusae over a range of temporal and spatial scales (Goy et al 1989;Graham et al 2001). It has also been shown that food availability, light, salinity, and temperature are all important to the strobilation of scyphistomae (i.e., the development of ephyrae by the sessile polyp) and the survival of medusae (Russell 1970;Purcell et al 1999;Lucas 2001). There is a growing awareness that large-scale climatic variation can lead to changes in zooplankton community com-position and abundance, and that this, in turn, can have major consequences for fisheries .…”

Pronounced interannual variability in the abundance of medusae of the jellyfish species Aurelia aurita, Cyanea lamarckii, and Cyanea capillata (Phylum Cnidaria, Class Scyphozoa) in the North Sea was evident in data arising from the International Council for the Exploration of the Seas International 0-group Gadoid Surveys between 1971 and 1986. Possible climatic forcing of jellyfish abundance, via the North Atlantic Oscillation (NAO), was investigated with data on medusae from four areas of the North Sea (east of Scotland, north of Scotland, east of Shetland, and west of northern Denmark). There were significant inverse relationships between medusa abundance and the NAO Index (December-March) in two regions: west of northern Denmark (A. aurita r 2 ϭ 0.70, P ϭ 0.003, n ϭ 10; C. lamarckii r 2 ϭ 0.74, P ϭ 0.002, n ϭ 10) and east of Scotland (A. aurita r 2 ϭ 0.53, P ϭ 0.008, n ϭ 12). Fluctuations in the abundance of A. aurita and C. lamarckii medusae might be linked to hydroclimatic changes induced through atmospheric effects (as encapsulated in the NAO Index) on wind stress, temperature, and currents. These fundamental hydroclimatic changes alter the timing of spring phytoplankton blooms and zooplankton community composition. Predation by an abundance of medusae on zooplankton and ichthyoplankton could affect the North Sea ecosystem through top-down and bottom-up mechanisms. Because the NAO is presently in a high phase, climatic conditions could be serving to depress the abundance of medusae: a future reversal of the NAO might favor jellyfish and weaken the persistence or recovery of fisheries.

“…The medusae in turn reproduce by the release of planula larvae which develop again into polyps. In accordance with these development stages A. aurita populations are found predominantly in those areas where suitable hard substrata are available for the benthic scyphistoma (Lucas, 2001). …”

“…Scyphozoans like A. aurita have a life cycle consisting of planktonic sexually-reproducing medusae and benthic asexually-reproducing polyps (Möller, 1979;Gröndahl, 1988;Lucas, 2001). The benthic polyps need hard substrate to settle on.…”

This study assessed the impact of secondary hard substrate, as being introduced into marine ecosystems by the establishment of wind farm pillars, on the occurrence and distribution of the moon jelly Aurelia aurita in the southwestern Baltic Sea. A two-year data sampling was conducted with removable settlement plates to assess the distribution and population development of the scyphozoan polyps. The data collected from these samples were used to set up a model with Lagrangian particle technique. The results confirm that anthropogenic created hard substrate (e.g. offshore wind farms) has the potential to increase the abundance of the Aurelia aurita population. The distribution of wind farm borne jellyfish along Danish, German and Polish coasts indicates conflicts with further sectors, mainly energy and tourism.
