Mass Mortality of Shallow-Water Temperate Corals in Marine Protected Areas of the North Aegean Sea (Eastern Mediterranean)

Hydrobiology, 2023
Coral mortality is a global phenomenon of increasing magnitude, correlated with climate change. Prolonged marine heatwaves have particularly affected the north Aegean Sea in summer 2021, threatening shallow-water stony corals, such as Balanophyllia ...

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

Zoological 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

Physiological changes during torpor favor association with Endozoicomonas endosymbionts in the urochordate Botrylloides leachii

Frontiers in Microbiology, 2023
Environmental perturbations evoke down-regulation of metabolism in some multicellular organisms, leading to dormancy, or torpor. Colonies of the urochordate Botrylloides leachii enter torpor in response to changes in seawater temperature and may survive ...

Tracking Invasion Histories in the Sea: Facing Complex Scenarios Using Multilocus Data [PDF]

, 2012
In recent years, new analytical tools have allowed researchers to extract historical information contained in molecular data, which has fundamentally transformed our understanding of processes ruling biological invasions.

Immunobiology of compound ascidians, with particular reference to Botryllus schlosseri: state of art [PDF]

Invertebrate Survival Journal, 2008
The phylogenetic position of invertebrate chordates closely related to vertebrates explains the increasing interest towards tunicate immunobiology. Most of the tunicates are ascidians which, like all other invertebrates, rely only on innate immunity for ...

Seasonal variation in Azumiobodo hoyamushi infection among benthic organisms in the southern coast of Korea

Parasites & Vectors, 2015
Background Recent studies have reported that soft tunic syndrome (STS) in the edible ascidian Halocynthia roretzi is caused by the kinetoplastid parasite Azumiobodo hoyamushi.

Fertilization of Ascidians: Gamete Interaction, Self/Nonself Recognition and Sperm Penetration of Egg Coat

Frontiers in Cell and Developmental Biology, 2022
Fertilization is one of the most important events in living organisms to generate a new life with a mixed genetic background. To achieve successful fertilization, sperm and eggs must undergo complex processes in a sequential order.

Antarctic ascidians respiration rate under increasing sedimentation

, 2020
The file includes the respiration rate (milligrams of Oxygen per gram of dry mass (without tunic) per day) of three antarctic solitary ascidians (Cnemidocarpa verrucosa, Molgula pedunculata and Ascidia challengeri) under increasing sediment ...

Mechanisms of Sperm–Egg Interactions: What Ascidian Fertilization Research Has Taught Us

Cells, 2022
Fertilization is an essential process in terrestrial organisms for creating a new organism with genetic diversity. Before gamete fusion, several steps are required to achieve successful fertilization.

Ascidian notochord elongation

Developmental Biology, 2019
The elongation of embryo and tissue is a key morphogenetic event in embryogenesis and organogenesis. Notochord, a typical chordate organ, undergoes elongation to perform its regulatory roles and to form the structural support in the embryo. Notochord elongation is morphologically similar across all chordates, but ascidian has evolved distinct molecular
