title: Artificial earth sculpture

authors: Blair, W.N.

abstract: William Newsham Blair (1841-91) was born in Scotland, and trained there as an engineer and surveyor. He emigrated to Dunedin at the end of 1863 and took employment with the Otago Provincial Survey Department at the beginning of the new year. In 1871, he became District Engineer of Public Works, and in 1878, the year after election as a Member of the Institution of Civil Engineers, was appointed Engineer-in-Charge of Public Works in the South Island. In 1884, Blair moved to Wellington as Assistant Engineer-in-Chief. In 1890, he became Engineer-in-Chief and Under Secretary for Public Works (Furkert 1953: 117).
During his career as engineer, Blair had many opportunities to travel throughout New Zealand. For example, in the 1870s he travelled widely throughout Otago and Canterbury (including traversing the Southern Alps five times) while on reconnaissance surveys for possible railway routes, and in the 1880s he visited the King Country to report on the proposed North Island Main Trunk. It was no doubt on these and similar journeys that Blair became very much aware of the changes which man was making to the landscape. A few earlier writers had expressed concern about the wholesale clearing of the natural vegetation, but none had noted the scale of man-induced erosion and change. Similarly Blair refused to accept a commonly held theory that rainfall increased if forests were planted, and decreased if the land was denuded. In some ways, Blair may be compared with George Perkins Marsh in the United States. Over two decades earlier Marsh had already recognised that man was a potent force in changing his environment. It is interesting to speculate if indeed Blair had found his inspiration in the writings of this American naturalist.

title: Testing the effectiveness of the mt DNA Cytochrome c oxidase subunit 1 (COI) gene locus for identifying species of Polychaete worm (Polychaeta: Annelida) in New Zealand

authors: Brett, Christy Donna

subjects: mt DNA

abstract: The ability to accurately identify species is fundamental to ecological research and environmental monitoring. Current taxonomic identifications often rely on differentiation of morphologically ambiguous characters, and a process of categorization which is tedious and often leads to misidentifications. This is compounded by the presence of cryptic taxa, which may be prevalent among Polychaete worms (Polychaeta: Annelida). With increased access to genetic techniques, Cytochrome c oxidase subunit I has been suggested as a possible aid to assist in the discrimination of species resources.
In this study, I tested the hypothesis that the mtDNA COI gene locus is effective in discriminating morphologically recognised species of Polychaete worms.
A 543 base-pair fragment of the COI locus was successfully extracted for 111 individuals from 16 out of 20 morphologically recognised species. Average intraspecific divergences were 0.8 %, ranging from 0 % to 5 %. Average interspecific variation was 26.4 %, ranging from 13.8 % to 36.8 %. The lowest divergences were found between two Nereid species (13.8 %), and two Glycera americana species (17.2 %). Relatively high maximum divergences of over 30 % suggest that some species may have reached a divergence saturation level, which may partially explain why familial groupings in constructed trees were not monophyletic. Divergences within the different Nereid species - a group previously known to have morphologically cryptic species - did not reveal the presence of any cryptic taxa. Pairwise comparisons showed a clear divide between percentages of intra- and interspecific divergences, and the suggested threshold of 11 % is effective for the taxa investigated here.
On the basis of these results, I conclude that sequence variation in the mtDNA COI gene locus is effective in discriminating morphologically recognised species of Polychaete worms, but may not be appropriate for deeper (e.g. generic or familial) phylogenetic relationships among taxa.

title: Sixty years of adult learning in Aotearoa New Zealand: Looking back to the 1960s and beyond the 2020s

authors: Amundsen, Diana Leigh

abstract: This article offers a historical analysis of the past sixty years of adult learning in Aotearoa New Zealand and critically appraises events which have shaped today’s context. Drawing on a substantial body of research by key adult educators, researchers and scholars, the review assesses historical, socio-cultural, and political factors that influenced adult learning policies and practices. First, a brief discussion is given of traditional Māori education, colonisation, bi-culturalism and multiculturalism for relevance to the Aotearoa New Zealand context. Next, a historical analysis is offered in a decade-by-decade review. Looking back over the past sixty years, this historical analysis exposes key influences which have shaped adult learning in Aotearoa, and discusses trends emerging as significant future directions going into and beyond the 2020s.
