Seasonal cycles of the Penilia abundance were compared, over five coastal regions-the north-western part of the Black Sea (Sevastopol Bay), the northern part of the Adriatic Sea (Gulf of Trieste), the north-eastern Atlantic (Vigo coast), the north-western

Penilia avirostris is an important component of the mesozooplankton of shelf waters during the stratification period. This study investigates the feeding ecology of P. avirostris under natural dietary conditions in the NW Mediterranean during their summer

The cladoceran Penilia avirostris and three tunicate species, Oikopleura dioica, Dolioletta gegenbauri and Thalia democratica, form a mesozooplankton group which ingests a wide range of particles from pico- to micro- plankton, grows rapidly due to asexual

Populations of Penilia avirostris were studied in Guanabara Bay, southeastern Brazil, to assess temporal variations in the densities of parthenogenetic and gamogenetic individuals, length, and brood size. The abundance of P. avirostris varied widely during

An ecological model for the simulation of the population dynamics of the cladoceran Penilia avirostris in Guanabara Bay, a tropical Brazilian bay, was developed. The simulated curve gave a good fit, in time and intensity, to the exponential increase and
