The growing number of artificial structures in estuarine, coastal and marine environments is
causing “ocean sprawl”. Artificial structures do not only modify marine and coastal …

Human-induced stresses of overfishing, eutrophication, climate change, translocation and
habitat modification appear to be promoting jellyfish (pelagic cnidarian and ctenophore) …

Although there are various indications and claims that jellyfish (ie, scyphozoans, cubozoans,
most hydrozoans, ctenophores, and salps) have been increasing at a global scale in recent …

Over the last 50 years there has been an increased frequency and severity of negative

Among marine organisms, gelatinous zooplankton (GZ; cnidarians, ctenophores, and
pelagic tunicates) are unique in their energetic efficiency, as the gelatinous body plan allows …

The pelagic tunicates, gelatinous zooplankton that include salps, doliolids, and
appendicularians, are filter feeding grazers thought to produce a significant amount of …

The excess input of nutrients that triggers eutrophication processes is one of the main
destabilizing factors of coastal ecosystems, being coastal lagoons prone to suffer these …

Plankton form the base of marine food webs, making them important indicators of ecosystem
status. Changes in the abundance of plankton functional groups, or lifeforms, can affect …

Large population fluctuations of jellyfish occur over a variety of temporal scales, from weekly
