Omnivory by the small cosmopolitan hydromedusa Aglaura hemistoma [PDF]
Limnology and Oceanography, 2005 We investigated the feeding of the small hydromedusa, Aglaura hemistoma(bell diameter , 4 mm), to determine if it occupies a trophic position similar to that of large medusae. Feeding was examined using gut-content analysis of preserved and unpreserved medusae and by analyzing prey-capture events using microvideographic techniques.

Diel Vertical Dynamics of Gelatinous Zooplankton (Cnidaria, Ctenophora and Thaliacea) in a Subtropical Stratified Ecosystem (South Brazilian Bight). [PDF]
PLoS ONE, 2015 The diel vertical dynamics of gelatinous zooplankton in physically stratified conditions over the 100-m isobath (~110 km offshore) in the South Brazilian Bight (26°45'S; 47°33'W) and the relationship to hydrography and food availability were analyzed by ...

High spatial heterogeneity of two planktonic cnidarian species related to the variability of a shelf-slope front at short time scales [PDF]
Scientia Marina, 2016 We investigated the variability in the mesoscale distribution of the siphonophore Muggiaea atlantica and the hydromedusa Aglaura hemistoma in relation to the rapid spatial oscillations of the shelf-slope front off the Catalan coast (NW Mediterranean ...
