Cook Strait as a field for ecological study: Plankton

[First paragraph(s)...]
By and large the planktonic population of one water mass will differ from that of an- other either in the species present or in the composition of the population. Where several water masses are mixing the planktonic organisms collected at a point in the mixture will depend on which water masses are contributing towards the environment at that point. The relative abundance of the several populations may well be indicative of the proportions of the respective contributions and of the length of time since these were made.

Cook Strait as a field for ecological study: Marine geology of Cook Strait

[First paragraph(s)...]
TVarious aspects of the marine geology of Cook Strait of concern to the biologist may be considered under the following heads:
Morphology: The division of the central and southern areas of the Straits into regions is possible: a. Even, gently-sloping bottom in from 0 to 50 fathoms, e.g., Cloudy Bay, Palliser Bay.
b. Near-flat but irregular topography, 50- 70 fathoms. This is the outer edge of the shelf, and is diversified by minor basins
c. Basin area, D'Urville Island to mid- strait off Tongue Point, maximum depth 200 fathoms.

The delineation of natural areas in New Zealand: Discussion

[First paragraph(s)...]
THE CHAIRMAN opening the discussion said the problem was to try to establish some community of pattern in the various ecological and biological factors present in the areas propounded as natural and see to what extent it was possible to make broad delineations of these areas Various points had emerged from the papers: the apparent significance of the 38th parallel; the effect of Cook Strait, which is a barrier to certain reptiles and some of the birds, but not to worms.

The delineation of natural areas in New Zealand: Former faunal areas: some sub-fossil evidence

[First paragraph(s)...]
Any discussion of former faunal areas based on the distribution of fossil or sub- fossil bones is complicated when those bones are of various geological ages. Nevertheless, study of the regions in which the genera and species of moa are found makes possible some tentative conclusions.

The delineation of natural areas in New Zealand: The distribution of New Zealand reptiles

[First paragraph(s)...]
The Reptilia, in New Zealand, are represented by four groups: the marine turtles (Testudinates), the tuatara (Rhynchocephalia), the marine snakes (Ophidia), and the lizards (Sauria). The marine turtles and snakes being stragglers have little bearing on the subject.
The tuatara once inhabited almost the entire area, but today is more or less restricted to sixteen islands.

The delineation of natural areas in New Zealand: Natural areas in the distribution of freshwater fish

[First paragraph(s)...]
New Zealand possesses some twenty species of native freshwater fish, but they have been so little studied that natural areas based on their distribution cannot yet be defined. More is known of the distribution of the introduced fish and this paper deals with the the two main species.
