title: Distribution and Dispersal of Aquatic Invertebrates in the Waitomo Stream

authors: Jenkins, Bevan Ronald

abstract: A survey of the distribution and dispersal of aquatic macro invertebrates was carried out in the Waitomo caves catchment, located South of Hamilton, New Zealand. Eight sites were selected along the Waitomo stream. The sites represented a longitudinal gradient that flowed from the native forested, headwaters to pasture, then into native forest remnants, before flowing into pasture and onto the glowworm caves at the bottom of the catchment. It was found that both the benthic and drift fauna underwent a change in community composition along the length of the catchment. Initially, the diversity decreased and invertebrate abundance increased as the stream flowed from forest to pasture. There was also a change in community composition from 'sensitive' taxa e.g. Plecoptera and Archichauliodes diversus to more 'enrichment' tolerant eg chironomids and Austrosimulium sp. However the biota of the stream was 'restored' upon the stream flowing into a forest remnant, the Aranui reserve. There was also a seasonal reduction in drift of invertebrates from the Waitomo stream over winter. Additionally significant differences were found for many drift taxa between forest and pasture sites. Suggestions as to future research topics and recommendation for restoration of the catchment streams and biota were made.

title: The chemistry of Pseudocyphellaria impressa S. Lat. in New Zealand

authors: Wilkins, Alistair L.

abstract: As part of a detailed study of the nomenclature and taxonomy of the New Zealand
species of Pseudocyphellaria it has been noted that the chemistry of the P. impressa
(Hook & Taylor) Vainio aggregate, that is species with a markedly faveolate (honeycomb-
like) upper surface and a green algal phycobiont, is particularly complex.
The 45 lichen substances detected fall into four distinct groupings, here designated
as 'Codings'. The aim of this contribution is to investigate suitable methods for
revealing this chemical assemblage by t.l.c. and, as far as is currently possible, to
identify the range of substances. No conscious attempt is made to assign the four
chemical Codings to particular taxa or species groupings; the taxonomy of the
group will be discussed elsewhere. The four Codings proved to be remarkably
uniform and constant considering the range and number of substances involved;
such variation that occurred was only in the presence and concentration of accessory
substances.
Although this work only concerns New Zealand material, similar patterns occur
in related taxa of the group present in southern South America, south-east Australia
and Tasmania.

title: Ki te kapu o taku ringa - In the palm of my hand [Photography exhibition at Gallagher Academy of Performing Arts]

authors: Hill, Rodrigo

subjects: Mātauranga Māori

abstract: (Exhibition catalogue)
The title Ki te kapu o taku ringa is taken from a line of
‘Maioha mō Waikato’ by Kīngi Tāwhiao. Ejected from their
homelands he and his Waikato brethren took refuge with
their Maniapoto relations in Te Nehenehenui. The maioha
was composed expressing Kīngi Tāwhiao’s love for his
homelands, and his solastalgic holding fast to those lands
‘... in the palm of his hand.’ The words from the song-poem
were used as guide to our research and photography practice.
