A learning design framework for community resilience: International and transdisciplinary perspectives on a boundary object
(Elsevier BV, 2022)To equip graduates to respond to sustainability challenges, higher education institutions are developing programs and innovative pedagogical approaches that target new types of 21st century knowledge and skills. Resilience ... -
A kraft mill-integrated hydrothermal liquefaction process for liquid fuel co-production
(MDPI, 2020)There is a growing awareness of the need to mitigate greenhouse gas emissions and the inevitable depletion of fossil fuel. With the market pull for the growth in sustainable and renewable alternative energy, the challenge ... -
Acute hypophagia and changes in c-Fos immunoreactivity in adolescent rats treated with low doses of oxytocin and naltrexone.
(2021-12-23)A recent case report has shown that an adjunctive oxytocin + naltrexone (OT + NTX) treatment promoted more robust hypophagia and body weight reduction than OT alone in an adolescent male with hypothalamic obesity after ... -
Causality and the fate of climate litigation: The role of the social superstructure narrative
(Wiley, 2022)Climate litigation has become a strategic tool to push for climate justice, including compensation for losses caused by climate change. Many cases rely on the establishment of a causal relationship between the defendants' ... -
The coastal habitats of Tairawhiti: A review of the scientific, local, and customary knowledge
(Environmental Research Institute, 2021)In Aotearoa/New Zealand, regional councils and unitary authorities have a range of responsibilities for decision making in the coastal and marine area (CMA). The New Zealand Coastal Policy Statement (2010), in policy 11, ... -
Extreme heat in New Zealand: a synthesis
(Springer Science and Business Media LLC, 2022)Extreme heatwaves are among the fastest-changing meteorological hazards in a warming world. While likely also true for New Zealand, significant knowledge gaps exist relating to the current and future risks associated with ... -
Bacterial cellulose synthesis by gluconacetobacter xylinus: Enhancement via fed-batch fermentation strategies in Glycerol media
(2021)Bacterial cellulose (BC) is an abundant polysaccharide, which is secreted by several genera of bacteria. It has remarkable characteristics, which include high purity, high tensile strength, high biocompatibility and ... -
Development and experimental analysis of a pneumatic based dibbling machine for a forestry nursery
(MDPI AG, 2022)The rejection rate of tree stock in a forestry nursery can be as high as 35%. This is attributed to plant physiology, poorly trained seasonal workers and unsophisticated equipment. It is estimated that approximately 5% of ... -
A dated phylogeny shows Plio-Pleistocene climates spurred evolution of antibrowsing defences in the New Zealand flora
(Wiley, 2021)Some plant traits may be legacies of coevolution with extinct megafauna. One example is the convergent evolution of ‘divaricate’ cage architectures in many New Zealand lineages, interpreted as a response to recently extinct ... -
AusTraits, a curated plant trait database for the Australian flora
(Nature Portfolio, 2021)We introduce the AusTraits database - a compilation of values of plant traits for taxa in the Australian flora (hereafter AusTraits). AusTraits synthesises data on 448 traits across 28,640 taxa from field campaigns, published ... -
Sediment aluminium content of Lakes Rotorua and Rotoehu: 2020 monitoring survey
(Environmental Research Insitute, 2021)The application of aluminium sulphate (alum) to freshwater systems is commonly undertaken in order to restrict the availability of dissolved reactive phosphate (DRP), thereby reducing phytoplankton growth. Alum treatment ... -
Islands in the sand: are all hypolithic microbial communities the same?
(Oxford University Press (OUP), 2021)Hypolithic microbial communities (hypolithons) are complex assemblages of phototrophic and heterotrophic organisms associated with the ventral surfaces of translucent minerals embedded in soil surfaces. Past studies on the ... -
Antarctic ecosystems in transition - life between stresses and opportunities
(Wiley, 2020)Important findings from the second decade of the 21st century on the impact of environmental change on biological processes in the Antarctic were synthesised by 26 international experts. Ten key messages emerged that have ... -
High diversity and local endemism in Aotearoa New Zealand's groundwater crustacean fauna
(Wiley, 2021)We used DNA barcoding to assess the diversity and distribution of New Zealand's groundwater amphipods and isopods (Crustacea) and to determine whether biodiversity and endemism within tectonically active New Zealand are ... -
Historical biogeography of the Gondwanan freshwater genus Boeckella (Crustacea): Timing and modes of speciation in the Southern Hemisphere
(Wiley, 2021-09-14)Aim We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate (1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance ... -
The Trichoptera barcode initiative: a strategy for generating a species-level Tree of Life
(Royal Society Publishing, 2016)DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for ... -
The bounded inverse Weibull distribution: An extreme value alternative for application to environmental maxima?
(Elsevier BV, 2021)There has long been interest in making inferences about future low-probability natural events that have magnitudes greater than any in the past record. Given a stationary time series, the unbounded Type 1 and Type 2 ... -
Linking proximal ignimbrites and coeval distal tephra deposits to establish a record of voluminous Early Quaternary (2.4–1.9 Ma) volcanism of the Tauranga Volcanic Centre, New Zealand
(Elsevier, 2022)The Tauranga Volcanic Centre (TgaVC) of the North Island, New Zealand, was active from 2.95 to 1.9 Ma. It lies temporally and spatially between the currently active Taupō Volcanic Zone, one of the most productive regions ... -
Assessment of impacts of mechanical spat harvesting on the surf clams of Te Oneroa a Tōhē
(2020)Much of the mussel spat used to seed mussel aquaculture farms throughout New Zealand is sourced from Te Oneroa a Tōhē (90 Mile Beach) in Te Hiku (far north of New Zealand). The mussel spat washes ashore attached to seaweed ... -
Phytoplankton nutrient limitation in Lake Rotorua
(2022)Lake Rotorua is one of 12 lakes jointly managed by the Rotorua Lakes Council, Te Arawa Lakes Trust and the Bay of Plenty Regional Council under the Rotorua Te Arawa Lakes Programme. The lake is currently classified as ...
