Tunicate feeding filters

open access: yes, 2003
International audienceThis review discusses the structure and operation of the fine mesh `mucous' feeding filters of tunicates. The function of the endostyle in producing the feeding filter and the different ways in which the filter is deployed are also ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Ingested microscopic plastics translocate from the gut cavity of juveniles of the ascidian Ciona intestinalis

open access: yesThe European Zoological Journal, 2019
Small plastic particles, named microplastics, are abundant in the marine environment and can be ingested by marine organisms. Species with different feeding strategies can be differently affected by the presence of microplastics.

Opportunistic Feeding and Parasite Assemblages in Sei Whales (Balaenoptera borealis) From Southern Chile Revealed by DNA Metabarcoding

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

A phytochelatin synthase gene in the solitary tunicate Ciona intestinalis

open access: yes, 2013
The major thiol-containing molecules involved in controlling the level of intracellular ROS in eukaryotes, acting as a nonenzymatic detoxification system, are metallothioneins (MTs), glutathione (GSH) and phytochelatins (PCs).

Squills vs. Hyacinths – A revised genus delimitation in Hyacinthinae (Hyacintheae, Scilloideae, Asparagaceae) based on phylogenomics

open access: yesTAXON, Volume 75, Issue 5, October 2026.
Abstract Scilla s.l. (Asparagaceae: Scilloideae) represents a notable Mediterranean geophyte radiation, yet genus delimitation in subtribe Hyacinthinae has long suffered from inconsistent and conflicting generic concepts. A limited set of informative morphological characters and recurrent shifts in circumscription have repeatedly hindered progress ...

Tunicate-mimetic nanofibrous hydrogel adhesive with improved wet adhesion

open access: yes, 2018
The main impediment to medical application of biomaterial-based adhesives is their poor wet adhesion strength due to hydration-induced softening and dissolution. To solve this problem, we mimicked the wound healing process found in tunicates, which use a

Ascidian Tunicate, Botryllus schlosseri (Pallas, 1766) infestation on Seahorse

open access: yes, 2011
An unusual infection by tunicate ascidians on the trunk part of a seahorse caught by gill netting in the Eastern Black Sea Region of Turkey was observed. The colour, zooid diameter and width of the zooids colony of tunicate was determined.
