title: Ecophysiological adaptations of the lichen genera pseudocyphellaria and sticta to south temperate rainforests

authors: Green, T.G. Allan

abstract: Temperate rainforests are a poorly researched habitat with respect to lichen ecophysiology in comparison to desert and polar regions. The evergreen, broadleaf forests provide a dim, moist environment that is relatively stable throughout the year. Lichens are abundant in both quantity and species diversity with the large foliose genera Sticta and Pseudocyphellaria normally being dominant, visually and in terms of biomass. These lichens exhibit a great diversity of both form and habitat range. Physiological and morphological adaptation has also been demonstrated. Pseudocyphellaria dissimilis shows changes in thallus water storage capacity with evaporative demand and is also highly shade-adapted. The species has the lowest light saturation and compensation values for photosynthesis yet known for lichens (20 and 1-μmol m−2s−1, PAR, respectively). Unexpectedly it is also highly desiccation-sensitive with some thalli being killed after only 20 h exposure to 15% relative humidity. Photobiont versatility is also a feature of these genera. Photosymbiodemes occur, i.e. a single thallus containing both green algal and cyanobacterial sectors. Because the different sectors have the same fungal partner and grow in the same habitat, it is possible to investigate whether particular physiological traits are photobiont determined. The ability to recover photosynthetic activity in humid air is confined to thalli with green algal photobionts whilst the inability of thalli containing cyanobacterial photobionts to tolerate high light stress may be related to their lack of a protective xanthophyll cycle.

title: Re-designing Greenstone for Seniors

authors: Bennett, Erin Kay

subjects: Greenstone

abstract: The golden generation have a wealth of experience and knowledge from throughout
their lifetimes that younger generations wish to retain. In our technology filled world
an obvious means of collecting this information is electronically. Digital library col-
lections are increasingly used by libraries and large institutions to record their large
amounts of information but they can also be used for personal collections.
Seniors are often willing and keen to impart their years of experience upon people
of the younger generation but time is not always on their side as they grow older.
Throughout a lifetime a person could collect large amounts of papers, diaries, pho-
tos and media but the time it takes to organise these documents can be long and
exhausting and the person's health is not always at its best in old age.
Greenstone is a suite of software for creating digital libraries, which are organised
collections of documents. Greenstone has the ability to distribute collections either
using a server or CD-ROM, and provides advanced searching and organization tools.
While Greenstone is a versatile and useful tool in creating digital collections, its in-
terface is not designed for senior users. Seniors are commonly perceived to have
more physical and mental disadvantages as they get older. These disadvantages can
dramatically affect how usable seniors find a piece of software.
The aim of this thesis is to investigate how usable the current Greenstone interface
is for use by seniors and to re-design the interface so that Greenstone may be more
easily used by senior users. This thesis focuses upon what types of documents and
descriptive data seniors would like to include in a collection about their life. This is
to ascertain exactly what parts of the interface must be improved when it comes to
metadata and classifiers. The results of this investigation also helped in the creation
of a customised metadata set for senior users use.

title: Ko Te Kawa Tūpanapana i ngā Hau Tūpua a Tāwhiri-mātea : The validation, revitalisation and enhancement of Māori environment knowledge of weather and climate

authors: Skipper, Apanui Sonny

subjects: Maori Environmental knowledge

abstract: KO TE KAWA TŪPANAPANA I NGĀ HAU TŪPUA A TĀWHIRI-MĀTEA – THE RITUALISTIC FORMS GOVERNING THE SUPERNATURAL WINDS OF TĀWHIRI-MĀTEA
Mankind has always gazed skyward observing the im immense power generated by forked lightning when it strikes the land. The resounding thunder booming across the landscape never failed to capture the awe and imagination of a people. Māori were no different. The legacy of their Polynesian ancestors, who populated most of the Islands of Te Moana-nui-a-Kiwa, the largest ocean on the planet, based on belief, courage, and navigational expertise, honed over many millenia, reached Aotearoa approximately in the 12 century. These highly skilled ancestors from the tropics applied a formalised process of settling a new land. It also required their own weatherlore to be recalibrated to the local conditions, in order to survive in a much harsher, colder climate.

Over the centuries the descendants of these early Polynesian settlers, developed an extensive localised knowledge of weather, climate, and seasonal indicators to accurately predict daily weather, monthly or annual climate conditions. The ongoing lessons learned especially after experiencing a fatality were incorporated into cultural practices of important everyday activities such as ahuwhenua, te mahi hī ika, kohi rongoā, whakaako tamariki, gathering pounamu, whakatū rāhui, and kaitiakitanga, in order to minimise further loss of life.

Formal recognition of these contributions was made at the inaugural Māori Climate Forum in Wellington in 2003, where a number of Māori elders highlighted the importance of giving a greater account of Māori knowledge of environmental change. Among the many priorities identified for research at this forum, an opportunity based on a challenge from a Māori elder led to the development of a pilot project to explore traditional Māori understandings of weather–climate variability and change. 

One of the key outcomes from this work was the identification of Māori environmental indicators to anticipate local weather and climate conditions and thereby manage the risk associated with weather-climate extremes. However, in spite of the work achieved, there remain unanswered questions about the use and ongoing efficacy of environmental indicators to forecast and monitor weather and climate risks, including how new opportunities might be created to promote learning about subtle signals in nature that can reveal much about changes in weather and climate conditions. 

Due to the fact that many of the elders that provided the basis of this thesis have passed away, a great sense of responsibility has remained with me to complete this research. To identify the gaps in the previous research, to ground-truth it, to consolidate and carefully document the level of localised environmental knowledge of weather and climate specifically with iwi from Tainui-Hauraki, Te Whānau-a-Apanui, and Ngāi Tahu. A total of 56 interviews and 17 group wānanga were conducted during 2009-2016. Examples of Māori Environmental Knowledge were also sourced from numerous personal conversations with knowledge holders from 1989-2003, adding to the body of knowledge that was analysed to provide further context. A conceptual framework coined `Ngā Whenu Tapu e Waru’ was created from identifying the key themes of the interviews to inform how Māori Environmental Knowledge was described in the three regions. This study has yielded understandings of wind, rain, thunder, lightning, and cloud classifications; weather and climate indicators; spiritual signs of misfortune and death; memory techniques; longitudinal weather predictions, and lunar calendars in each region.

This thesis is underpinned by a Kaupapa Māori theory and research methodology that links to a body of transformative research and literature conducted by Māori scholars based on the knowledge and experience of tūpuna  Māori.
