Farm machinery use and maize yields in China: An analysis accounting for selection bias and heterogeneity
(Wiley, 2020-07-24)
Crop production in developing and emerging countries is increasingly dependent on the usage of farm machinery. However, it remains unclear whether low-productive and high-productive farmers benefit equally from farm machinery ...

Risk factors for the conservation of saltmarsh vegetation and blue carbon revealed by earthquake-induced sea-level rise
(Elsevier, 2020-12-01)
Vegetated coastal ecosystems (VCEs) are in global decline and sensitive to climate change; yet may also assist its mitigation through high rates of ‘blue’ carbon sequestration and storage. Alterations of relative sea-level ...
Observations from radar scans of grape vines conducted over a growing season
(IEEE, 2020-01-16)
A series of S-band radar scans of grape vines conducted over the growing season including post-harvest. From these radar scans two-dimensional mass distributions were obtained and these are presented for two different ...
Variation in the yak lipin-1 gene and its association with milk traits
(Cambridge University Press on behalf of Hannah Dairy Research Foundation, 2020-05)
The aim of this research was to identify variation in the yak lipin-1 gene (LPIN1) and determine whether this variation affects milk traits. PCR-single stranded conformational polymorphism (PCR-SSCP) analysis was used to ...
Biotic interactions drive ecosystem responses to exotic plant invaders
(American Association for the Advancement of Science, 2020-05-29)
Ecosystem process rates typically increase after plant invasion, but the extent to which this is driven by (i) changes in productivity, (ii) exotic species' traits, or (iii) novel (non-coevolved) biotic interactions has ...
Dynamics of phosphorus exchange between sediment and water in a gravel-bed river
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020)
Phosphorus (P) stores in gravel-bed rivers are released for uptake by periphyton when pH levels exceed 8.5. The Tukituki River has low alkalinity water and frequently experiences periphyton blooms, and daytime pH > 9 during ...
Effect of increasing dietary proportion of plantain on milk production and nitrogen use of grazing dairy cows in late lactation
(CSIRO Publishing, 2021-03-04)
Context: Plantain has shown promise as a forage that can mitigate nitrogen (N) losses from farm systems, although adoption and regulation requires knowledge of the minimum amount of forage area or diet quantity to observe ...
Consumer willingness to pay for food safety attributes in China: A meta-analysis
(Taylor & Francis, 2020-05-06)
Food safety incidents in China have led to increased research into consumers’ willingness to pay (WTP) for food safety attributes. This paper employed meta-regression models to analyze the empirical results of WTP estimates ...
Perspectives: The downside to discounting - and a couple of alternatives
(2020-07-06)
Desperate times calls for desperate measures – but letting desperation drive you to discounting can end up with disastrous results. Offering discounts as part of getting your business open, attracting customers and getting ...
