The vertical distribution and migration of plankton organisms may have a large impact on their horizontal dispersal and distribution, and consequently on trophic interactions. In this study we used video-net profiling to describe the fine scale vertical distribution of Mnemiopsis leidyi in the Kattegat and Baltic Proper. Potential diel vertical migration was also investigated by frequent filmin...

1.1 Caspian Sea The complex history of the Caspian Sea formation has lead to a variety of different habitats. Like Australia, the Caspian Sea became isolated thousands of years ago (Plate 1). This isolation led to the speciation of many rare animals in particular the sturgeon. The Caspian Sea is the biggest enclosed body of water on Earth, having an even larger area than that of the American Gr...

The study reports the data on distribution and predatory impact of gelatinous macroplankton mesozooplankton in inshore waters Crimea April 2016. In areas, comprised Scyphomedusae Aurelia aurita (Linnaeus, 1758) three ctenophore species (Mnemiopsis leidyi A. Agassiz, 1865, Beroe ovata Bruguire, 1789, Pleurobrachia pileus (O. F. Müller, 1776). biomass dominated everywhere varied from ~ 62 to 330 ...
