Ian Atkinson was one of the most versatile ecologists ever to work on our shores, an original thinker and true allrounder whose broad scope covered plants, animals, and soils. A generalist of the old school rather than a narrowly focussed specialist, his career was notable for collaboration with experts in a variety of fields and for lasting contributions to vegetation mapping, soil mapping, volcanic succession, introduced rodent ecology, mammal-plant interactions, island ecology, and restoration ecology. A stalwart of the New Zealand Ecological Society, he held a number of offices, serving as Secretary 1960–1962, Vice-President 1965 and 1983–1985 and President 1985–1987, and he was also a longtime Councillor from 1962 till 1983. He was made a Life Member in 2001. Ian was born of English parents Leonard Gray Atkinson (1894–1965) and Winifred Atkinson née Goddard (1904–1994) in Hamilton on 6 October 1932. His father, an electrical draughtsman, had arrived here from London in 1924 to work for the Public Works Department, helping design Arapuni Power Station, the first in a long line of hydro-electric plants built by the government on the Waikato River. Leonard went Ian Atkinson on a family holiday on Big Island, Hawaii, 17 July 2007. (Photo: Cynthia Petersen).

: Biodiversity conservation in Aotearoa New Zealand is of high importance, and efforts to protect vulnerable populations from decline has garnered broad public support. Conservation efforts have been further highlighted with the 2016 announcement of Predator Free 2050, a nationwide goal to eliminate key invasive mammalian predators from New Zealand by the year 2050. Hands-on labour is often needed to complete conservation initiatives, and New Zealand conservation volunteers have shown themselves to be an abundant, effective, and oft-used workforce. However, there is limited knowledge of conservation volunteers on a national scale. This exploratory research aimed to determine what motivates conservation volunteers in New Zealand, gauge their attitudes toward modern-day conservation, and summarise their demographic information. Through a nationwide survey of 986 New Zealand conservation volunteers in 2018, we found that they have a higher than median age, income, education, and are predominantly Pākehā/NZ European and likely retired. The median conservation volunteer has volunteered within 10 km of home for 10 hours a month for 6 years. The conservation and cultural context in New Zealand could be reflected in volunteer motivations and attitudes. New Zealand conservation volunteers are motivated by a feeling of responsibility, with some referencing the Māori concept of kaitiakitanga. There were elements of wanting to right past wrongs and volunteers’ perceived role as stewards of their local environment. Conservation volunteers overwhelmingly agree with the stated goals of Predator Free 2050 and are in favour of current and potential future methods of pest control. They are, however, significantly less confident that Predator Free 2050 goals will be achieved. Conservation volunteers contribute to goals like Predator Free 2050 through their significant voluntary labour. We hope this research contributes to a better understanding of conservation volunteers in New Zealand and leads to strengthening the support for these volunteers and the many community groups they represent.

: Monitoring breeding outcomes of cryptic nocturnal species such as the North Island brown kiwi ( Apteryx mantelli ) is an important aim for conservation management in New Zealand. While fitting male kiwi with radio transmitters enables incubation burrows to be found and monitored, it is invasive and expensive. Remote monitoring methods (without handling of birds) are preferable. Here we investigate the extent to which it is practical to find North Island brown kiwi incubation burrows based on remote monitoring, motivated by anecdotal reports that incubating males call close to their incubation burrow on first emergence. We test this observation, and then use it to demonstrate how a combination of acoustic recorders, human listening, and trail cameras can be deployed to locate the burrow with minimal disturbance, based on the male’s first call of the night. Our analysis of an incubating brown kiwi male’s first call in the evening as a function of distance from the burrow shows that for more than half the time monitored he called within 10 minutes of leaving his burrow and that on these nights, he was usually less than 35 m from it. Along with backtracking of kiwi footsteps, this enables the localisation of the burrow. We outline a workflow for the method based on our experience and discuss how it can be made more efficient and usable in the future. Our method facilitates the finding of nests, and hence of chicks, without the need for adult kiwi to be fitted with transmitters

Urban reserves have the potential to retain relatively high biodiversity. However, populations of the taxa within them can have reduced genetic diversity and, if gene flow between populations is inhibited by urbanised surroundings, can become genetically differentiated. Here we determine whether differences in population genetic differentiation and diversity can be observed in the leaf litter inhabiting weevil Geochus politus along the urban-rural gradient spanning Waitākere Ranges Regional Parkland and suburbs of West Auckland, New Zealand. Nine microsatellite markers were developed and screened across 300 individuals from nine sampling locations. Pairwise FST values, a principal coordinates analysis, and Bayesian estimates of population structure all demonstrated that the most urban site was strongly differentiated from the others. This site also had the lowest heterozygosity and highest FIS values, potentially indicating a loss of genetic variation and a greater degree of inbreeding, although not to a dramatic extent. Differentiation was also observed among sampling locations within continuous forest, suggesting that both urbanisation and other landscape variables are influencing gene flow between these locations. This study highlights the potential for urban reserves to harbour significant diversity and emphasises the importance of maintaining these sites.

: To be considered an effective pollinator, a floral visitor must not only be able to remove pollen but also transfer this pollen to a receptive conspecific stigma. While studies of diurnal pollination are commonplace, our understanding of the effectiveness of nocturnal pollinators is limited largely because of the difficulties of doing these studies at night. As a result of this, the way in which moths transfer pollen between flowers has been understudied globally, despite many authors suggesting they could be significant contributors to pollination. Here, we tested whether moths are capable of transferring pollen between flowers under experimental conditions using a fluorescent pollen-tracker powder. A flower-feeding taxon (Noctuidae: Ichneutica plena ) and non-feeding taxon (Hepialidae: Wiseana spp.) were contained overnight with flowering shoots of putatively moth-pollinated Leptospermum scoparium and Pimelea prostrata ( I. plena only), and putatively bird-pollinated Crocosmia × crocosmiiflora . Moths were able to transfer pollen tracker between flowers for both of the putatively moth-pollinated species, while no pollen tracker was removed from putatively bird-pollinated flowers. Both the feeding and non-feeding moth taxa were able to transfer pollen tracker between flowers; however, the feeding taxon could be considered a more effective pollinator because of the greater proportion of individuals both carrying and transferring pollen tracker compared with the non-feeding taxon. This study provides experimental evidence that moths may contribute to the pollination of L. scoparium and P. prostrata , and suggests a reassessment of the pollination ecology for these species is warranted

: Aotearoa New Zealand’s conservation management has had a strong focus on offshore islands, though this investment is at risk from human-influenced factors such as biosecurity incursions and wildfire. During the last century several wildfires have occurred on Moutohorā (Whale Island), Bay of Plenty, which is a location for six threatened plant and three threatened animal species. Conservation and cultural management on Moutohorā over the last several decades has restored the island to become the most densely vegetated it has been since before humans arrived, albeit with a very different composition. The Prometheus fire-growth simulation model was used to produce a series of deterministic fire extent maps, which were compiled into seasonal burn probability maps. The average simulated fire extent was 53.2 ha, with a maximum area of 129.9 ha (or approx. 84% of the entire island), with 23% of fires not growing past 0.01 ha. Fires that start in summer, the western end of the island, and in mānuka and/or kānuka had the highest mean and maximum fire extent. Burn probability maps are a key step in quantifying the spatial fire risk for important conservation locations such as Moutohorā.
