A Polychaete hunchback Ortholog

open access: yesDevelopmental Biology, 2001
We report the first characterization of a segmentation gene homologue in the basal polychaete Capitella capitata using a pan-annelid cross-species antibody to the hunchback-like gene product. In flies, the gap segmentation gene hunchback (hb) encodes a C(2)H(2) zinc-finger transcription factor that plays a pivotal role in patterning the anterior region

Predicting the composition of polychaete assemblages in the Aegean coast of Turkey

open access: yesFrontiers in Marine Science, 2016
Benthic infaunal species and communities have been extensively used to evaluate quality of the marine environment. Within the MSFD, community composition is addressed most commonly through Descriptor 6 (Seafloor integrity), criterion 6.2 (Condition of ...

Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]

open access: yes, 2004
Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...

Multiple Trophic Levels in Soft-Bottom Communities

open access: yes, 1985
In order to assess the general applicability of recent field experiments with predatory infauna, we searched the literature and found 48 well-documented cases of infaunal consumption by such predators.
