title: Biases in the metabarcoding of plant pathogens using rust fungi as a model system

authors: Makiola, Andreas

subjects: Cloning

abstract: Plant pathogens such as rust fungi (Pucciniales) are of global economic and ecological importance. This means there is a critical need to reliably and cost‐effectively detect, identify, and monitor these fungi at large scales. We investigated and analyzed the causes of differences between next‐generation sequencing (NGS) metabarcoding approaches and traditional DNA cloning in the detection and quantification of recognized species of rust fungi from environmental samples. We found significant differences between observed and expected numbers of shared rust fungal operational taxonomic units (OTUs) among different methods. However, there was no significant difference in relative abundance of OTUs that all methods were capable of detecting. Differences among the methods were mainly driven by the method's ability to detect specific OTUs, likely caused by mismatches with the NGS metabarcoding primers to some Puccinia species. Furthermore, detection ability did not seem to be influenced by differences in sequence lengths among methods, the most appropriate bioinformatic pipeline used for each method, or the ability to detect rare species. Our findings are important to future metabarcoding studies, because they highlight the main sources of difference among methods, and rule out several mechanisms that could drive these differences. Furthermore, strong congruity among three fundamentally different and independent methods demonstrates the promising potential of NGS metabarcoding for tracking important taxa such as rust fungi from within larger NGS metabarcoding communities. Our results support the use of NGS metabarcoding for the large‐scale detection and quantification of rust fungi, but not for confirming the absence of species.

title: Hangarau me te Māori: Māori and technology

authors: Keegan, Te Taka Adrian Gregory

subjects: Māori

abstract: A sign of a vibrant, healthy developing nation is the adaptation and uptake of new technologies. Māori have a long, but mostly unrecognised, history of ingenious innovation and adaption of new technologies. This chapter will reveal Māori ingenuity through discussion of historic examples and modern media usages by Māori, and the future implications these have for Māori.
Technology can be defined as tools, devices and machines that have been developed by the application of scientific knowledge. Māori technology, then, is Māori tools, devices and machines that have been developed by the application of Māori scientific knowledge. This chapter discusses some examples of innovative Māori technology and their adoption in both historic and modern times. It includes sections on historic Māori technology, Māori media innovation and Māori adoption of Internet technology. Two sections are further expanded on: Māori in social networking sites and te reo Māori in technology. The chapter concludes with the authors' thoughts on how the adoption of new technologies will shape tikanga Māori and te reo Māori into the future.
