Chemical Diversity and Biological Activity of Secondary Metabolites Isolated from Indonesian Marine Invertebrates

open access: yesMolecules, 2021
Marine invertebrates have been reported to be an excellent resource of many novel bioactive compounds. Studies reported that Indonesia has remarkable yet underexplored marine natural products, with a high chemical diversity and a broad spectrum of ...

Behavioural Responses of the Colonial Sea Squirt Botrylloides violaceus Oka to Suspended Food Micro-Particles in Laboratory Cultures

open access: yesJournal of Marine Science and Engineering, 2020
Violet sea squirts are noteworthy model organisms, because they provide insights into various physiologic processes, including cell senescence, ageing, apoptosis and allorecognition. Consequently, their culture is critical to permit experimental studies.

Can stand the heat – ecology of the potentially invasive ascidian Styela plicata along the Mediterranean coast of Israel

open access: yesFrontiers in Marine Science, 2023
IntroductionBoth colonial and solitary ascidians (Chordata, Ascidiacea) have been gathering attention due to their impact on coastal environments. The solitary ascidian Styela plicata was first observed along the coast of Israel in 2014. It is considered

Assessing Efficacy of “Eco-Friendly” and Traditional Copper-Based Antifouling Materials in a Highly Wave-Exposed Environment

open access: yesJournal of Marine Science and Engineering, 2023
Biofouling control on human-made structures and seagoing technologies that minimize environmental impacts is a major focus of research in marine industries. However, the most widely used antifouling (AF) method is still copper-based coatings.

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Using Oyster Shells for Customized 3-D Structures for Monitoring Ecosystem Shifts on Ascidians Diversity

open access: yesFrontiers in Marine Science, 2022
Biofouling communities are broadly distributed and there is a growing need to understand, monitor, and prevent their dispersal and colonization.

Tunicates [PDF]

open access: yesCurrent Biology, 2016
Tunicates, also called urochordates, are an extremely diverse subphylum of the Chordata, a phylum that also contains the vertebrates and cephalochordates. The tunicates seem to have undergone especially rapid evolution: while remaining exclusively marine, they have radiated to occupy habitats ranging from shallow water, to near shore to the open ocean ...

Note to: Hox gene cluster of the ascidian, Halocynthia roretzi, reveals multiple ancient steps of cluster disintegration during ascidian evolution

open access: yesZoological Letters, 2019
Background In the previous paper published in 2017, we described the structure of Hox gene cluster of the ascidian, Halocynthia roretzi, and discussed the scenario for the disintegration of Hox gene clusters during evolution of ascidians. The description

The Pharmacological Potential of Nonribosomal Peptides from Marine Sponge and Tunicates

open access: yesFrontiers in Pharmacology, 2016
Marine biodiversity is recognized by a wide and unique array of fascinating structures. The complex associations of marine microorganisms, especially with sponges, bryozoans, and tunicates, make it extremely difficult to define the biosynthetic source of

Endozoicomonas are specific, facultative symbionts of sea squirts

open access: yesFrontiers in Microbiology, 2016
Ascidians are marine filter feeders and harbor diverse microbiota that can exhibit a high degree of host-specificity. Pharyngeal samples of Scandinavian and Mediterranean ascidians were screened for consistently associated bacteria by culture-dependent ...
