Capitella teleta , a new species designation for the opportunistic and experimental Capitella sp. I, with a review of the literature for confirmed records
TLDR
Morphologically, C. teleta is a highly opportunistic species and appears to be the same as the C. capitata identified from southern California as the “polluted zone indicator” by D.J. Reish in the late 1950s. Expand
Ultrastructure of the gonad and gametogenesis in the eastern oyster,Crassostrea virginica. I. Ovary and oogenesis
TLDR
It is suggested that the follicle tells play some important role during oogenesis but probably are not the major source of yolk precursors, while the VCT celas are probably the main source of nutrients for vitellogenesis. Expand
Ultrastructure of the gonad and gametogenesis in the eastern oyster,Crassostrea virginica. II. Testis and spermatogenesis
TLDR
It is suggested that the neutral term “accessory cells” be applied to bivalve testicular somatic cells until more detailed studies are available to justify the use of “Sertoli cell” and other descriptive terms which have previously been adopted from other taxa only distantly related tobivalves. Expand
Ultrastructure of sperm development and mature sperm morphology in three species of commensal bivalves (Mollusca: Galeommatoidea)
TLDR
The rotational asymmetry and the presence of perimitochondrial glycogen deposits in these sperm are unusual in the Bivalvia and may be associated with fertilization specializations and larval brooding common among galeommatoideans. Expand
Evolutionary radiation in polychaete ovaries and vitellogenic mechanisms: their possible role in life history patterns
TLDR
Comparative studies have revealed a correlation between mechanisms of yolk synthesis and the breeding patterns of polychaetes with the rate and type of vitellogenesis being related to the frequency of breeding. Expand
Gonadal morphology and gametogenesis in the sea pen Pennatula aculeata (Anthozoa: Pennatulacea) from the Gulf of Maine
TLDR
The expulsion of sperm cysts suggests that they function as primitive spermatophores, perhaps as a way of reducing sperm dilution in the Gulf of Maine, USA, in August 1993. Expand
Ovarian morphology and oogenesis in Aurelia aurita (Scyphozoa: Semaeostomae): ultrastructural evidence of heterosynthetic yolk formation in a primitive metazoan
TLDR
The trophocyte-oocytes relationship in oocytes of A. aurita is reminiscent of the trophonema-oocyte relationship in anthozoans and supports the belief that the Anthozoa and Scyphozoa share a close phylogenetic relationship. Expand
Ultrastructure of gametogenesis in a chemosynthetic mytilid bivalve (Bathymodiolus childressi ) from a bathyal, methane seep environment (northern Gulf of Mexico)
TLDR
Despite the relatively stable methane seep environment and presumed continuous availability of nutrients, reproduction parallels that of littoral mytilids, suggesting some phylogenetic constraints on the capacity for variability in gametogenic processes in the family Mytilidae. Expand
