Marine gelatinous zooplankton of the Egyptian waters: a review
Egyptian Journal for Aquaculture, 2020Gelatinous plankton is formed by representatives of cnidarians (true jellyfish), ctenophores (comb jellies) and tunicates (salps). Gelatinous groups are a conspicuous, but relatively little studied component of marine ecosystems; in recent years its importance in pelagic food webs has gained increased awareness.

A physical context for gelatinous zooplankton aggregations: a review
Hydrobiologia, 2001The magnitude and extent of jellyfish blooms are influenced not only by the biology and behavior of the animal, but also by the geographic setting and physical environment. Hydrography alone is often thought to cause or favor gelatinous zooplankton aggregations, however, it is clear that interactions between biology of the animal and physics of the ...

Modelling of Arctic Gelatinous Zooplankton
, 2021 The profound environmental shifts in the Arctic region lead to far-reaching alterations of the composition and structure of marine populations and communities and cause pronounced quantitative and qualitative changes in ecosystem functioning.

Seasonal changes in the gelatinous zooplankton community and hydromedusa abundances in Korsfjord and Fanafjord, western Norway [PDF]
Marine Ecology - Progress Series, 2007 Quantitative seasonal studies on gelatinous zooplankton in Norwegian fjords are scarce. We recorded the quantitative composition of the gelatinous zooplankton community in Korsfjord and Fanafjord during 1 yr. Thirty-six species or genera of hydromedusae,

Measurement of material properties of two gelatinous, coastal zooplankton
The Journal of the Acoustical Society of America, 2007Acoustic scattering models for zooplankton are often used to transform acoustic data (backscattered energy) into biological units (number or size of animals). In order for these models to be used successfully, accurate descriptions of the animals themselves are required including: Species, size, orientation, and their material properties, specifically ...

Trophic ecology of Arctic gelatinous zooplankton
The overarching goal of this dissertation is to reject the hypothesis of gelatinous zooplankton (GZP) as a trophic dead end for the Arctic and sub-Arctic seas. To do so, I investigated the role of GZP in the diet of different invertebrate and fish species, during different seasons and at different locations.openaire +1 more source
Locomotor adaptations of some gelatinous zooplankton.
Symposia of the Society for Experimental Biology, 1986Swimming behaviour and locomotor adaptations are described in chaetognaths, larvacean tunicates, some cnidaria, and thaliacean tunicates. The first two groups swim by oscillating a flattened tail, the others by jet propulsion. In chaetognaths, the locomotor muscle fibres are extensively coupled and relatively sparsely innervated, they exhibit compound ...

The Quantitative Significance of Gelatinous Zooplankton as Pelagic Consumers
1984Gelatinous Zooplankton, including the planktonic coelenterates, ctenophores, molluscs and tunicates are ubiquitous and often abundant members of both neritic and oceanic communities. The quantitative impact of these primary and secondary consumers on their food stocks has been estimated in previous studies by calculating the proportion of the prey ...

Movement ecology of gelatinous zooplankton: approaches, challenges and future directions
Journal of Experimental BiologyABSTRACT Understanding the movement patterns and behavior of marine organisms is fundamental for numerous ecological, conservation and management applications. Over the past several decades, advancements in tracking technologies and analytical methods have revolutionized our ability to study marine animal movements.

Mesozooplankton and gelatinous zooplankton in the face of environmental stressors
2020Mesozooplankton and gelatinous zooplankton communities in Chesapeake Bay (CB) and the northern Adriatic Sea (NAS) have been subject to similar stressors over recent decades, including warming waters, overfishing, urbanization, and eutrophication. Direct comparisons between the systems are clouded by the lack of standardized and sustained long-term ...
