Effects of temporal variability of disturbance on the succession in marine fouling communities in northern-central Chile [PDF]

open access: yes, 2007
We investigated the effects of temporal variability in a disturbance regime on fouling communities at two study sites in a northern-central Chilean bay. Fouling assemblages grown on artificial settlement substrata were disturbed by mechanical removal of ...

Transcriptional Analysis of the Endostyle Reveals Pharyngeal Organ Functions in Ascidian

open access: yesBiology, 2023
The endostyle is a pharyngeal organ with an opening groove and cilia in invertebrate chordates (amphioxus and ascidian) and cyclostomate (lamprey), serving as a filter-feeding tract and thyroid-secreting location.
