The ascidian prophenoloxidase activating system [PDF]
Invertebrate Survival Journal, 2009 Phenoloxidases/tyrosinases initiate melanin synthesis in almost all organisms, and are involved in different biological activities such as the colour change of human hair and the browning or blackening of fruit skin etc.

Parasite infection shapes the pathobiome and behavior of marine zooplankton
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract When assessing the total impact of disease in a host, it is important to consider not only the disease‐carrying agent but also all symbionts, as they affect and are affected by the course of disease. This concept of a pathobiome is increasingly recognized in disease ecology, but is not well‐investigated in natural systems.

Marine Drugs, 2013 Fertilization and embryo development that occur in sea water are sensitive to xenobiotics from anthropogenic sources. In this work, we evaluated the influence of two antifouling biocides, tributyltin (TBT) and diuron, on the reproductive mechanisms of ...

Protostigmata in ascidians [PDF]
Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1913 It has been showed that at a certain stage in the ontogeny of Ascidians there is usually a definite number of stigmata or gill slits, which are elongated dorsorventrally and arranged in a longitudinal series on each side of the pharynx. To these the name protostigmata was given by Garstang in 1892.

Bijdragen tot de Dierkunde, 1924 Through the kindness of Dr. C. J. VAN DER HORST of Amsterdam, I have had the opportunity of examining and reporting on the collection of ascidians that he made at Curaçao, Dutch West Indies, in April and May, 1920. The collection represents only the littoral fauna of the island; all the specimens appear to have been obtained in very shallow water on ...

Cellular aspects of allorecognition in the compound ascidian Botrylloides simodensis
Invertebrate Survival Journal, 2014 When colonies of the compound ascidian Botrylloides simodensis contact each other at their cut surfaces, either fusion or rejection occurs. Contact between genetically compatible colonies leads to the complete fusion of their tunics and vasculature ...

Colony specificity in Botrylloides leachi. I. Morphological aspects [PDF]
Invertebrate Survival Journal, 2006 We studied colony specificity in the colonial ascidian Botrylloides leachi which, as in other botryllid ascidians, leads to either fusion or non-fusion between contacting colonies.

Meroterpenes from Marine Invertebrates: Structures, Occurrence, and Ecological Implications
Marine Drugs, 2013 Meroterpenes are widely distributed among marine organisms; they are particularly abundant within brown algae, but other important sources include microorganisms and invertebrates.

Ascidian gene-expression profiles.
Genome biology, 2002 With the advent of gene-expression profiling, a large number of genes can now be investigated simultaneously during critical stages of development. This approach will be particularly informative in studies of ascidians, basal chordates whose genomes and embryology are uniquely suited for mapping developmental gene networks.

Fouling invertebrates from PVC plates at Chahué Marina, Oaxaca, Southern Pacific coast of Mexico [PDF]
Check ListThe port fouling fauna from Mexico has recieved greater study in the last 15 years. By improving our knowledge of fouling invertebrates on artificial substrates on the Southern Pacific coast of Mexico, we can better understand their ...
