First record of Herdmania momus (Ascidiacea: Pyuridae) from the central Mediterranean Sea [PDF]

open access: yes, 2013
The solitary ascidian Herdmania momus, an Indo-Pacific species that has been introduced into the Mediterranean Sea via the Suez Canal during the past century, has so far been restricted to the Levantine region. Here we record H.

SPERM CHEMOTAXIS IN OIKOPLEURA DIOICA FOL, 1872 (UROCHORDATA: LARVACEA)

open access: yesThe Biological Bulletin, 1983
An alcohol extract of unfertilized eggs of the larvacean, Oikopleura dioica, can attract sperm over a distance of at least 80 µm from an artificial source. The sperm, which normally swim in wide circles or straight lines, alter their path to form small loops between straight or slightly curved segments directed up the gradient.

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Metamorphosis and lncRNAs: A Close Relationship

open access: yesgenesis, Volume 64, Issue 2, April 2026.
ABSTRACT The classical definition of metamorphosis is a post‐embryonic transformation, such as from a tadpole to a froglet. However, recent studies suggest this process occurs to some degree in all vertebrates, as the underlying endocrine and molecular pathways are highly conserved. With the advent of high‐throughput sequencing, transcriptomic data for

\uabAspects of cell production in mantle tissue of Ciona intestinalis L. (Tunicata, Ascidiacea)\ubb [PDF]

open access: yes, 2005
Renewal of cell population is needed in the tunic of ascidians, as the tunic cells are involved in many biological functions. Tunic cells are thought to arrive by migrating across the mantle epithelium into the tunic from the blood lacunae or the ...

Measurement of refractive indices of tunicates’ tunics: light reflection of the transparent integuments in an ascidian Rhopalaea sp. and a salp Thetys vagina

open access: yesZoological Letters, 2017
Background Tunic is a cellulosic, integumentary matrix found in tunicates (Subphylum Tunicata or Urochordata). The tunics of some ascidian species and pelagic tunicates, such as salps, are nearly transparent, which is useful in predator avoidance ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Zebrafish as a model for Catel–Manzke syndrome—identification and characterization of the zebrafish TGDS ortholog

open access: yesThe FEBS Journal, Volume 293, Issue 8, Page 2248-2269, April 2026.
Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.
