Report on the 2013: Rapid assessment survey of marine species at New England Bays and Harbors [PDF]

open access: yes, 2014
Introduced species (i.e., non-native species that have become established in\ud a new location) have increasingly been recognized as a concern as they have\ud become more prevalent in marine and terrestrial environments (Mooney and\ud Cleland 2001 ...

The Fetal Allograft Revisited: Does the Study of an Ancient Invertebrate Species Shed Light on the Role of Natural Killer Cells at the Maternal-Fetal Interface?

open access: yesClinical and Developmental Immunology, 2008
Human pregnancy poses a fundamental immunological problem because the placenta and fetus are genetically different from the host mother. Classical transplantation theory has not provided a plausible solution to this problem.

Phenoloxidase and cytotoxicity in the compound ascidian Botryllus schlosseri

open access: yesDevelopmental & Comparative Immunology, 1998
The vacuoles of morula cells (MC) of the colonial ascidian Botryllus schlosseri contain phenoloxidase (PO). As the release of their vacuolar content at the border of incompatible contacting colonies is associated with the formation of necrotic masses which characterize the rejection reaction, the role of PO in Botryllus cytotoxicity was investigated ...

Marine Invaders in the Northeast: Rapid Assessment Survey of Non-native and Native Marine Species of Floating Dock Communities, August 2003 [PDF]

open access: yes, 2005
In his seminal book on The Ecology of Invasions by Animals and Plants, Elton (1958) laid the foundation for the science of biological invasions. He identified the importance of human-mediated vectors as means of transporting organisms to new locations ...

The hemocytes of Polyandrocarpa mysakiensis: morphology and immune-related activities [PDF]

open access: yesInvertebrate Survival Journal, 2009
A preliminary study of the hemocytes of developing buds of the compound ascidian Polyandrocarpa misakiensis was carried out at the light microscope level for a better understanding of their biological role. Similarly to other ascidians, P.

Partial Biochemical Characterization of Humoral Factors Involved in the Nonfusion Reaction of a Botryllid Ascidian, Botrylloides simodensis [PDF]

open access: yes, 1984
By means of an in vivo bioassay technique based on the micro-injection of blood plasma, it has been demonstrated that the blood plasma of Botrylloides simodensis has a specific activity corresponding to the colony specificity or allogeneic ...

THE DEVELOPMENT OF THE BUD IN BOTRYLLUS

open access: yesThe Biological Bulletin, 1941
The bud arises as a disc-like thickening of the anterior atrial wall, consisting of a small number of columnar cells transformed from the atrial epithelium, overlain by an equivalent area of unmodified epidermis. The polarity of the disc and subsequent organism is an extension of that of the parental tissue, with regard both to the antero-posterior and

Amyloid/Melanin distinctive mark in invertebrate immunity [PDF]

open access: yes, 2012
Protostomes and Deuterostomes show the same nexus between melanin production, and amyloid fibril production, i.e., the presence of melanin is indissolubly linked to amyloid scaffold that, in turn, is conditioned by the redox status/cytoplasmic pH ...
