title: Global distribution and environmental correlates of marine bioturbation

description: This repository contains the R scripts necessary for conducting the data analysis for the paper titled 'Global distribution and environmental correlates of marine bioturbation', authored by Shuang Zhang, Martin Solan, and Lidya Tarhan.

It includes five R files, which should be executed in the following order:

01-Db_L_data_compilation: Initial data exploration and compilation (calculating average Db and L over time)

02-Db_L_data_explore: Further data exploration and analysis

03-Machine_learning_train: Building the machine learning framework

04-Machine_learning_predict: Using the trained machine learning framework to predict global Db and L values

05-MPA_analysis: Marine Protected Area (MPA) analysis

The repository also contains all necessary data to run these scripts. In addition, this repository also contains the appendix figures for the bioturbation paper.

title: Flexibility of differentiation procedures in calculus

description: Calculus is perhaps the most widely taught and researched upper-secondary/post-secondary mathematics subject the world over. The research literature is amassing greater clarity around students’ understandings of calculus, yet calculus instruction tends to be at odds with this literature, maintaining a focus on procedural aspects of the subject. This current work explores one central procedural topic, differentiation, through the broader lens of procedural flexibility. Both students and experts calculated the derivatives to a collection of functions in multiple ways, selected their preferred method and commented on their preference. Many students demonstrated a knowledge of multiple procedures and an ability to select appropriate solutions. Experts produced a greater number of distinct solution methods, including some not found among the student responses. The primary impact of this paper is a more nuanced understanding of ‘flexibility’ as a construct, buttressed by contrasting student and expert data, especially as it concerns procedures in higher-level mathematics. These results are expected to contribute to a bridge between the research on and practice of calculus instruction.

title: Efficacy of an off-line constructed wetland for mitigating nitrogen loss from a pastoral catchment

description: Constructed wetlands are an established mitigation option for reducing contaminant loads from pastoral land in New Zealand. We assess the long-term performance of a 0.5 ha, off-line, horizontal surface flow wetland, installed on a dairy farm with the primary objective of nitrate removal. Over seven years the median removal rates for nitrate-nitrogen (NO<sub>3</sub>–N), total nitrogen and total suspended solids were 45%, 33% and 74%, respectively. Whilst dissolved reactive phosphorus (DRP) was initially removed, over time the wetland progressed to a small exporter of DRP. Median NO<sub>3</sub>–N mass removal was 417 kg yr<sup>−1</sup><sub>,</sub> which is considerable for such a small wetland, and equivalent to 7% of total modelled ‘farm-scale’ losses. Nitrate removal was found to be seasonal and although it could be simulated using a conventional wetland model with Arrhenius temperature dependence, the resulting joint estimates of <i>k</i><sub>20</sub> and <i>Θ</i> were uncertain. We estimate the NO<sub>3</sub>–N removal cost-effectiveness of the wetland (over a 25-year lifespan) to be NZ$34 kg N<sup>−1</sup>. We foresee opportunities for off-line constructed treatment wetlands to be an effective nitrate mitigation option in perennial drains and lowland streams in pastoral catchments, but also emphasise the need for on-going maintenance to ensure longevity of performance.

title: Biocontrol of St John’s wort (<i>Hypericum perforatum</i>) provides huge ongoing benefits to New Zealand agriculture

description: An ex-post economic evaluation of biocontrol of St John’s wort (SJW), <i>Hypericum perforatum</i>, in New Zealand (NZ), used ecological niche modelling, GIS-mapped land-use vulnerabilities and a logistic equation to predict that SJW could have infested 660,000 ha of low-value hill-country pasture. To calculate productivity losses, we assumed serious infestations of SJW caused 30% decreases in farm income per hectare. Investment in SJW biocontrol totalled NZ$0.28 million (2022 rates) associated with the 1943–1992 releases of the chrysomelid beetles, <i>Chrysolina hyperici</i> and <i>C. quadrigemina</i>, and the cecidomyiid gall midge, <i>Zeuxodiplosis giardi</i>. Biocontrol effectiveness increased linearly in our model from 1943 (when initial local defoliation occurred) to reach 99% control nationwide by 1993 (when SJW was no longer considered a significant agricultural weed). We estimate that SJW biocontrol in NZ provided a national benefit of NZ$15.5 million in 2022, with a historical benefit–cost ratio of 6254:1. Both figures remained large in sensitivity testing. Uncertainties remain concerning whether biocontrol caused all reductions in SJW, or whether SJW infestations were partially replaced by other weeds. Despite such caveats, benefits of SJW biocontrol to NZ appear huge and sustainable.

title: Estimating the extent of urchin barrens and kelp forest loss in northeastern Aotearoa, New Zealand

description: On shallow rocky reefs in northeastern Aotearoa, New Zealand, urchin barrens are indicators of the ecosystem effects of overfishing reef predators. Yet, information on their extent and variability is lacking. We use aerial imagery to map the urchin barrens and kelp forests on reefs (&lt;30 m depth) across seven locations, including two long-established marine reserves and a marine protected area that allows recreational fishing. Urchin barrens were present in all locations and were restricted to reefs &lt;10–16 m deep. Urchin barrens covered 30% (7–49%) of shallow reefs in fished areas, with variation among and within locations likely related to the relative extent and topography of reefs and wave exposure. Within the marine reserves, barrens covered &lt;2% of shallow reefs. Long-term comparison of historical imagery at two fished locations demonstrates that current areas of urchin barrens were historically dominated by kelp forests, but barrens have persisted since at least the early 2000s. We estimate ∼30 km<sup>2</sup> of barrens exist across the region. This demonstrates the widespread nature of barrens, the potential long-term effectiveness of no-take marine protection in restoring urchin barrens, and the need for a multifaceted management approach to restore kelp forests and prevent further expansion of barrens.
