The nereidids from the western coasts of Mexico collected by the Allan Hancock Pacific Expeditions (1933-1970), which are deposited in the Natural History Museum of Los Angeles County, are analyzed. Twenty five species ...

The composition, distribution, and main assemblages of chaetognath species were examined throughout an annual cycle in Bahia de Banderas, Mexico. Zooplankton sampling was carried out during five seasons (1989 and 1991), ...

Rates of direct denitrification were measured using N-15 isotope techniques in intact sediment cores from fringe and basin mangroves in Terminos Lagoon, Mexico. Sediments were injected with (NO3-)-N-15 and the distribution ...

The distribution and composition of the holoplanktonic species of the family Typhloscolecidae are reported from 579 samples obtained over an extensive area in the eastern tropical Pacific Ocean. The EASTROPAC Oceanographic ...

Recent work has reported changes associated with physiological, morphological, and behavioural adaptation during the absorption of yolk reserves. The holobenthic endemic species Octopus maya was used to explore the energy ...

Larvae belonging to the family Sabellariidae (Polychaeta) were collected from the Gulf of California and in the Bahia de Banderas, on the west coast of Mexico. The oldest stages were selected for identification. The presence ...

In most studies on cephalopod growth, variability in initial size is masked by the assumption of a similar growth " starting point" for all hatchlings and by calculating the growth rate (GR) through modelling the average ...

Flume experiments with a scale-model of a wave driven seawater pump in monochromatic waves are described. A tuning mechanism optimises the pump performance by keeping it at resonance with the waves. The pumping process ...

Rhizocephalan parasitism is one of the most important biotic factors affecting commercially valuable crab species in families such as Portunidae and Lithodidae. In addition to the long term and permanent effects of this ...
