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: Robotic Pollination - Targeting kiwifruit flowers for commercial application

authors: Barnett, Josh

subjects: Pollination

abstract: This paper contains the initial evaluation of a novel platform mounted robotic pollination system. Advancement in artificial pollination is an important step forward in agricultural sectors due to the global decline of natural pollinators. Robotic pollination allows for potentially autonomous, precision operation; however, background research suggested that prior development in the area has been sparse. The featured wet-application robotic pollination system was capable of detecting >70% of flowers whilst driving at a slow-pace through kiwifruit orchard rows. Over 80% of flowers were robotically pollinated.

title: Researching collaborative artistic practice.

authors: Barbour, Karen

subjects: arts research

abstract: In this paper we offer discussion of collaboration in artistic practice, based on a two-and-a-half-year-long research project undertaken by artists/researchers at the University of Waikato, working in collaboration with local performers. Grounded in kaupapa M¯ori, feminist and phenomenological research methodologies, this research project provided a context for exploring existing understandings of collaborative processes in the arts, and for immersion in and development of alternative processes, across artistic mediums and cultures. Drawing on contemporary understandings of cross-cultural and intercultural practices in the arts, we discuss how shared conceptualisation of ideas, immersion in different creative processes, personal reflection and development over extended periods of time were found to foster collaboration. In this paper we will explore the value and nature of relationships within collaboration, and discuss how selfdetermination or tino rangatiratanga might be maintained within the context of collaborative performance art.
