Comparison of the life cycles of two populations of the polychaete Pereinereis cf. cultrifera from the Bay of Algiers (Mediterranean Sea)

open access: yesScientia Marina, 2008
The benthic phases of the life cycles of two populations of the polychaete Pereinereis cultrifera from the Bay of Algiers were investigated using field surveys. We found no differences in the life cycle of the two populations.

Benthic assemblage of Acquatina Lake (South Adriatic Sea): present state and long-term faunistic changes

open access: yesScientia Marina, 2010
A study on macrobenthos of Acquatina Lake, a transitional water basin, was performed in order to evaluate its present status and detect any faunistic changes after the digging of a larger connection with the open sea that has improved the hydrological ...

Mapping and classification of ecologically sensitive marine habitats using unmanned aerial vehicle (UAV) imagery and object-based image analysis (OBIA) [PDF]

open access: yes, 2018
Nowadays, emerging technologies, such as long-range transmitters, increasingly miniaturized components for positioning, and enhanced imaging sensors, have led to an upsurge in the availability of new ecological applications for remote sensing based on ...

Redescription of two species of Neanthes (Polychaeta, Nereididae) possessing a large notopodial prechaetal lobe

open access: yesScientia Marina, 2006
Phylogenetic analyses of “nereidids with paragnaths” indicated that species currently assigned to Neanthes sensu lato possessing a notopodial prechaetal lobe as large as the notopodial dorsal and ventral ligules were grouped in a separate clade with ...

Expression of Distal-less, dachshund, and optomotor blind in Neanthes arenaceodentata (Annelida, Nereididae) does not support homology of appendage-forming mechanisms across the Bilateria [PDF]

open access: yes, 2010
The similarity in the genetic regulation of arthropod and vertebrate appendage formation has been interpreted as the product of a plesiomorphic gene network that was primitively involved in bilaterian appendage development and co-opted to build ...
