title: Lakes water quality: Lake weed and pest animals

authors: Hon, Nick Smith

abstract: It is a pleasure to be invited to be part of this. The debate around fresh water in New Zealand has never been so strong and the delight in coming to Rotorua is that so many parts of New Zealand could learn from the experience here of pulling together a sciencebased collaborative approach for progress. Just listening to Professor David Hamilton's presentation, reinforcing how complex these fresh water issues are, signals the progress that has been achieved.

title: The effects of willow and willow control on wetland microfaunal assemblages in South Taupo Wetland

authors: Taura, Yvonne Michelle

subjects: Microfauna

abstract: Few studies have examined microfaunal assemblages living among Salix cinerea infestations in freshwater wetlands, or their responses to willow control treatment. The aim of this research was to quantitatively examine microfaunal assemblage abundance, richness and community composition among S. cinerea stands within the South Taupo Wetland, and determine whether these microfaunal assemblages are affected by willow growth and willow control treatment. 

Long-term effects of microfaunal community composition between native vegetation versus live and dead S. cinerea were examined in two blocks of the Waiotaka Scenic Reserve. Microfauna and physicochemical sampling were performed on three occasions to assess any seasonal effects on community composition. Results indicated there were no significant differences of physicochemical variables amongst natives, live and dead S. cinerea, with the exception of dissolved oxygen in late summer and canopy density in all seasons. This could be due to the S. cinerea trees representing stand-alone individuals, with a continuous canopy not yet formed. Overall, apart from shading and dissolved oxygen levels, environmental conditions of S. cinerea stands in this study seemingly made no significant difference to environmental variables. 

The abundant taxa found in the study were copepods, cladocerans and ostracods along with diverse species of rotifers, including the first record for New Zealand of the rotifer species Tetrasiphon hydracora. ANOVA indicated that there were no significant differences in microfaunal species richness between native, live and dead S. cinerea in any season. However, MDS ordination and ANOSIM results of species composition indicated that microfaunal assemblages were clustered in groups either side of the sand bar, suggesting that Blocks 1 and 2 functioned independently. This may be influenced by hydrological differences between Block 1 and 2 of the wetland reserve, with differing responses to fluctuating lake levels and seasonal rainfall, suggesting that microfaunal communities are regulated by hydrology rather than by the presence of willows or willow control.

 
Short-term effects of microfaunal community composition post willow control treatment were examined in Block 2 of the Waiotaka Scenice Reserve. Microfauna and physicochemical sampling were performed before and after treatment to assess effects on community composition post willow control treatment, using ground control method of drill and inject with a herbicide mix of metsulfuron. No significant differences in environmental variables were observed post treatment, with the exception of canopy density cover. Treated S. cinerea trees died and lost their leaves after ground application of metsulfuron. Microfaunal abundance and diversity were low before and treatment, suggesting that the application of metsulfuron made little difference to microfaunal assemblages.

Overall, the findings of this study indicate that the presence of S. cinerea seemed to make no significant difference to microfaunal abundance and diversity, possibly due to stand alone individuals rather than the formation of a dense canopy. Furthermore, ground control treatment of S. cinerea using metsulfuron had no direct or indirect impacts to microfaunal abundance and diversity. However, had the study been undertaken under a dense canopy of S. cinerea it is likely that the results may potentially be different.

title: Mā Muri Ko Mua: An introduction to the issues associated with the translation of the Pene Haare manuscript

authors: Tipene, Jillian

subjects: translation

abstract: Keywords: translation; translation theory; translation practice; Ngakuru Pene Haare; Te Rarawa; manuscript; Māori-English translation; ethically grounded translation.

In September 2007, a copy of a typewritten transcript of a manuscript dated 1923 and written by Ngakuru Pene Hare was given to a member of staff of the University of Waikato by Stephen Burke and Bella Wade, descendants of the author, who requested that the University provide a scholarly treatment and translation into English of the text. Also provided later were copies of letters written by the author and a copy of the original handwritten manuscript. The original manuscript, written in the Te Rarawa ki Hokianga dialect of te reo Māori of the author's time, consists of 239 leaves and contains accounts of at least 62 Ngāpuhi battles, most of which took place between 1820 and 1840. 

The research reported here seeks to identify issues and problems that must be addressed if a competent and ethically-grounded translation is to be produced.  Among the issues and problems identified are a number of critical ones. These include the paucity of information that is publicly available about the author, the context in which he lived and worked and the events about which he wrote. Also identified as being problematic are aspects of the text itself. Thus, for example, many of the conventions associated with contemporary writing in Māori (such as paragraphing and the signalling of word and sentence boundaries) are applied only sporadically. Some of the words and expressions used are archaic and/or esoteric, and symbolism that is deeply culturally-embedded characterises much of the text. Also of significance is the impact of writing on conventions associated with the oral transmission of information. The author's intention in producing the text is also identified as being of fundamental importance in relation to the process and product of translation, as are issues associated with the putative readership of that translation. Of paramount importance is the sacred and sensitive nature of the text itself and much of its content. 

In addressing these issues, a wide range of sources are drawn upon. These include the text itself and the transcription of the text, letters and other material written by, or directly influenced by the author, photographs that reveal important information about him, and a wide range of sources of information and opinion (written and oral) about the author and/ or the times and places in which he lived and the events about which he wrote. Also drawn upon is literature in the areas of linguistics and discourse analysis and the theory and practice of translation, including literature written by the growing number of Māori scholars who have focused on issues associated with translation involving Māori and English.

Among the recommendations made are that the translation, a gloss translation that includes explanatory notes, be undertaken, with tikanga Māori as guiding principles, under the mentorship of knowledgeable elders and in consultation with those to whom the manuscript belongs.
