title: Personal digital libraries: Keeping track of academic reading material

authors: Al-Anazi, Mohammed

subjects: computer science

abstract: This paper discusses optionsfor tracking academic reading material and introduces a personal digital library solution. We combined and extended the open source projects Zotero and Greenstone such that material can be easily downloaded and ingested into the combined system. Our prototype system has been explored in a small user study.

title: The role of thermal tolerance in biological invasion

authors: Wilde, Margot

abstract: Biological invasion and climate change are among the greatest threats to biodiversity currently. Several factors influence what makes a successful invasive species. Among these is the thermal tolerance of the invasive species. An organism’s thermal physiology underpins many aspects of its life, including the habitats in which it can survive, its reproduction and its development. Climate change is increasing global average temperatures at an unprecedented pace, which is increasing thermal stress on virtually all life around the world. These effects are particularly pronounced in ectotherms, which are reliant on environmental temperature to set their body temperature and drive their metabolism. Insects comprise a significant proportion of globally important invasive species. As well as being ectothermic, they have a complex life cycle with a number of developmental stages, all of which may be influenced by environmental temperatures. Invasive species can often tolerate or adapt to a broad range of environmental conditions. They may therefore be expected to have a broader thermal tolerance than their native counterparts, and than other invasives that have a narrower invaded range.  

This research used a blowfly model to investigate how thermal tolerance differed across temperatures, using a static temperature assay to measure thermal knockdown time. Key foci included the effects of both developmental heat acclimation and adult heat tolerance on thermal performance.  In Chapter 2, variation in adult heat tolerance was assessed across three temperatures (41℃, 42℃, 43℃) in five blowfly species invasive to New Zealand. I found that the two more globally invasive species in the study exhibited higher heat tolerance than the three less invasive Calliphora species, whose native ranges are generally more temperate. In Chapter 3, the effect of developmental temperature on adult knockdown time in a single species (Calliphora stygia) was assessed. I showed that C. stygia reared at the lowest temperature (18℃) had the highest knockdown time and the smallest body size, while those reared at 26℃ 1 exhibited  the shortest knockdown time and an intermediate body size, with those reared at 22℃ being the largest.   

Collectively, my results indicate that adult heat tolerance varies between invasive blowfly species, but that developmental acclimation temperature may not have a significant effect on adult heat tolerance. Given the increasing global temperatures seen with climate change, the effects of invasive species are likely to increase, with some species likely to do better than others in a warming world. Thermal performance will undoubtedly play a role in filtering out the ‘winners’ and ‘losers’, therefore further research into both heat and cold tolerance in both laboratory and field settings are crucial.

title: “If it don’t talk, it's not whakapapa data”: Conceptualising whakapapa data in a digital age

authors: Pēpi Tarapa‐Dewes, Ella

subjects: data protection

abstract: In Te Ao Māori, whakapapa is a sacred framework that connects all aspects of existence. Whakapapa is highly sensitive information and a taonga that requires active protection. But what can be considered whakapapa data in a digital age where data linkage is ubiquitous and the boundaries between personal and collective information are increasingly blurred? We explore this question through a case study with Ngāti Tiipa, a hapū that is actively engaged in its own data sovereignty research. Reflexive thematic analysis of whānau kōrero identified three types of whakapapa data, each denoting a specific kind of connection: 1) between relatives, both living and deceased; 2) between people and places of cultural significance; and 3) between people and the spiritual realm. Whānau concepts of whakapapa data tend to be context‐specific, suggesting that it is more useful to think of whakapapa data as dynamic and relational rather than a fixed, inherent attribute.
