Vessel collisions with small cetaceans worldwide and with large whales in the Southern Hemisphere, an initial assessment
Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern…
Past and present distribution, densities and movements of blue whales Balaenoptera musculus in the Southern Hemisphere and northern Indian Ocean
Blue whales avoid the oligotrophic central gyres of the Indian, Pacific and Atlantic Oceans, but are more common where phytoplankton densities are high, and where there are dynamic oceanographic processes like upwelling and frontal meandering.
Euryalinid Ophiuroidea (Echinodermata) from Australia, New Zealand, and the south-west Pacific Ocean
- A. Baker
A new subgenus of Asteroporpa Oestedt & Lutken is described and a new generic name, Astrosierra, is proposed for species of Conocladus H. L. Clark, which replaces Astroconus Doderlein.
Geographical variation in Hector's dolphin: Recognition of new subspecies of Cephalorhynchus hectori
Univariate and principal component analyses demonstrate that the North Island population of Hector's dolphin can be differentiated from the southern populations on the basis of several skeletal characters, plus genetic evidence of haplotype differences and absence of gene‐flow between populations are formally described.
Pilot trophic model for subantarctic water over the Southern Plateau, New Zealand: a low biomass, high transfer efficiency system
A NEW SPECIES OF BEAKED WHALE MESOPLODON PERRINI SP. N. (CETACEA: ZIPHIIDAE) DISCOVERED THROUGH PHYLOGENETIC ANALYSES OF MITOCHONDRIAL DNA SEQUENCES
The genetic data suggest a possible sister species relationship with the lesser beaked whale M. peruvianus, and suggest that M. hectori is confined to the Southern Hemisphere, while M.perrini is known to date only from the North Pacific.
Algae from Lake Miers, a solar-heated Antarctic lake

- Environmental Science
- 1 December 1967
Lake Miers, a permanently ice-covered thermally stratified lake in South Victoria Land, Antarctica, was sampled for plant life and 34 taxa are described, 6 species are new records for the Antarctic Continent and 11 are new to SouthVictoria Land.
Some Ophiuroidea from the Tasman Sea and adjacent waters
- A. Baker
Fifty-three species of ophiuroids from coastal and continental shelf stations off eastern and southern Australia, Norfolk Island, and western New Zealand are discussed and six new species are assigned to the genera Dictenophiura, Ophiocten,Ophiomusium, OPhioprium, and Amphistigma.
A new class of Echinodermata from New Zealand
During examination of echinoderms from sunken wood collected from depths between 1,057 and 1,208 m off the New Zealand coast, nine specimens of a small flattened discoidal invertebrate are discovered that represent the first new class of living echinoderm to be described since 1821.
The morphology, development and taxonomic status of Xyloplax Baker, Rowe and Clark (1986) (Echinodermata: Concentricycloidea), with the description of a new species
It is concluded that the Concentricycloidea are derived from the class Asteroides, and it is proposed that one of the extant families, Asterinidae, Korethrasteridae or Caymanostellidae, may share some precursor of valvatid-like type.
