title: Environmental and biogeographical drivers of the Leptospermum scoparium (mānuka) phyllosphere microbiome

authors: Noble, Anya Sophia

subjects: phyllosphere

abstract: A substantial body of research exists on the physiology and genetics of Leptospermum scoparium (mānuka); however, the mānuka phyllosphere has not yet been investigated. This research, therefore, provides the first exploration of the bacterial communities comprising the mānuka phyllosphere. In total, 89 samples were collected from five native mānuka forests during the November 2016 – January 2017 mānuka flowering season, and examined alongside spatial, environmental, and host-tree related metadata. Cultivation-independent methods, including DNA extraction and 16S rRNA gene PCR amplicon sequencing analysis, were used to characterise phyllosphere communities. Using a combination of statistical tests, the BLAST algorithm, and a PICRUSt analysis, a habitat-specific core microbiome comprising members of Acidobacteria, Alphaproteobacteria, Bacteroidetes, and Verrucomicrobia, was present in all samples. Distinct microbial biogeographical patterning was also identified in the mānuka phyllosphere whereby spatially structured gradients in environmental variables, such as temperature and precipitation, correlated with bacterial community structure.  The results from this study provide new insight pertaining to the structure, composition, and driving factors of the bacterial communities of the mānuka phyllosphere and shed light on theories of microbial ecology, such as microbial biogeography and core microbiomes. This research has the potential to open new avenues in both mānuka and microbial ecology fields of investigation within New Zealand.

title: Maori sustainable development in the 21st Century: The importance of Maori values, strategic planning and information systems

authors: Harmsworth, Garth

subjects: Development studies

abstract: The term ‘sustainable development’ has been widely used since the latter part of the 20th century. The concept implies economic and social development, economic growth, and environmental responsibility in order to sustain improved standards of living based on economic growth, to achieve some form of social equity, and to manage the environment in a sustainable way. Sustainable development should generally be at a rate that allows future generations to meet their needs without causing degradation of the natural environment, and should avoid economic or social decay. The concept has been debated and criticised by many as being ambiguous, untenable, and difficult to achieve, and frequently labelled part of global capitalism. But the concept provides a challenge to all of us, on how to balance economic, social, and cultural goals, while at the same time safeguarding and responsibly managing the environment for future generations. Attempts by indigenous peoples internationally to achieve sustainable development have been based on holistic approaches and frameworks that seek to balance economic, social, cultural and environmental objectives, and these provide effective models for viable sustainable development approaches. Māori Sustainable Development in Aotearoa-New Zealand is a term often used to describe a pathway to Māori autonomy, self-determination, the building of human and social capacity, as part of a strategic direction to capitalise on opportunities in the 21st century. This paper outlines research undertaken between 1998 and 2002 and funded by the Foundation for Research, Science, and Technology (FRST) in the programme “Māori Sustainable Development in Te Puku o Te Ika”, contract UOWX0005, simply referred to as the MSD programme. It focuses on the importance of determining Māori values, a vision, strategic planning and development of information systems as a holistic framework and process method to achieve Māori sustainable development.
