  • Jellyfish in changing world: portrayal, research and perception in the Northern Adriatic
    Malej, Alenka, 1948-
    People have been fascinated with jellyfish, admiring their fragile beauty and fearing sometimes fatal stings since ancient times. The study of jellyfish, here defined as pelagic cnidarians and ... ctenophores, has a long tradition in the Adriatic. The turn of the 20th century saw the "first golden age of gelata research" (Haddock 2004) in the Adriatic, although earlier reports of large jellyfish exist. C. Claus, D.J. Cori, A. Steuer, E. Graeffe, G. Stiasny R. Issel, V. Neppi, K. Babić, T. Krumbach, J. Hadži described morphology, development, ecology and evolution of jellyfish from the northern Adriatic. Unlike the "internet age" when interested individuals may access information easily, the public at that time did not have similar possibilities. Nevertheless, the public could enjoy jellyfish depicted in art, for example, in the glass sculptures created by the Blaschkas who received specimens from the northern Adriatic. The following decades saw a stagnation of jellyfish research in the northern Adriatic, partly due to turbulent times and partly because marine biologists focused research on fish, crustacean plankton and benthic organisms. The final two decades of the 20th century saw a resurgence in interest towards jellyfish stimulated by blooms of scyphomedusae, in particular painfully stinging Pelagia noctiluca during the 1980s. The main focus of research was ecology, behaviour and physiology of bloom-forming jellyfish and their trophic role in the "classical" food web. With few exceptions, jellyfish were considered as a trophic dead end and a nuisance for humans. On the other hand, public health issues due to jellyfish envenomations stimulated research on nematocysts, stings and venoms. In the last two decades realization of the potential repercussions of jellyfish for public health, tourism, fisheries, aquaculture, and marine ecosystem health brought the focus of research on long-term fluctuations, causes/drivers of jellyfish blooms and socio-economic impacts. Advances in field techniques, in particular diving and underwater photography, greatly improved life history research while molecular tools and modelling increased our ability to assess population connectivity. And finally, recent research and field observations have changed the view about jellyfish as trophic dead end. Moreover, the complementary notion that jellyfish provide beneficial services to humans and the ecosystem, in addition to their predominant perception as pest, has begun to emerge.
