COMPARATIVE MORPHOLOGY AND MOLECULAR PHYLOGENETIC ANALYSIS OF THREE NEW SPECIES OF THE GENUS KARENIA (DINOPHYCEAE) FROM NEW ZEALAND 1
TLDR
Molecular phylogenetic analyses of rDNA sequence alignments show that the new dinoflagellate species are phylogenetically distinct but closely related to K. mikimotoi and K. brevis. Expand
A revision of the supraspecific classification of the orders dictyoceratida dendroceratida and verongida class demospongiae
A reappraisal of all existing generic taxa within the group of Demospongiae lacking a mineral skeleton, and formerly referred to as the order Keratosa, has resulted n a new classification. Three or...
Spionid polychaete infestations of intertidal pacific oysters Crassostrea gigas (Thunberg), Mahurangi Harbour, northern New Zealand
TLDR
Oysters were more suitable for the half shell market and oyster condition was significantly greater towards the harbour channels and entrance, and mudworm infestations can be avoided by growing oysters above extreme low water neap and 0.5 m above the mud substratum. Expand
Reproductive biology of three sponge species of the genus Xestospongia (Porifera: Demospongiae: Petrosida) from the Great Barrier Reef
TLDR
Three species of the Petrosida, Xestospongia bergquistia, X. exigua, and X. testudinaria, were monitored for four years on a fringing reef at Orpheus Island, Great Barrier Reef, Australia and all were oviparous and female reproductive activity began prior to males becoming active. Expand
Phylogenetic Relationships within Theinvertebrata in Relation to Thestructure of Septate Junctions and the development of ‘Occluding’ Junctional Types
TLDR
The structures of 13 variants of invertebrate septate junction are reviewed on the basis offreeze-fracture, lanthanum tracer and thin-section studies, and a theory is put forward suggesting that in evolution a change from the septates to the tight junction could simply involve a modification of a ‘membrane spacing factor’, which allows the membranes of adjacent cells to come together at intervals.

A randomisation test of the null hypothesis that two cladograms are sample estimates of a parametric phylogenetic tree
TLDR
A protocol is proposed to test the null hypothesis that two trees estimate the true or parametric phylogeny and are no more different than would be expected due to sampling error. Expand
Speciation and biosynthetic variation in four dictyoceratid sponges and their cyanobacterial symbiont, Oscillatoria spongeliae.
TLDR
It is identified that at least one host switching event has occurred in this symbiosis of filamentous cyanobacterial symbiont Oscillatoria spongeliae, indicating that the chemical variation observed in these animals has a genetic foundation. Expand
