The National Policy Statement for Freshwater Management 2020 (NPS-FM) places a greater onus on resource managers to report on the state of freshwater ecosystem health, including fish. Routine fish monitoring is time intensive and is principally conducted in ‘wadeable’ stream reaches. In comparison, environmental DNA (eDNA) sampling is a relatively recent and rapid technique that likely detects fish and other vertebrate and invertebrate taxa over a broader spatial scale. In this study, we present data for five wadeable streams comparing diversity derived from multi-year standardised electrofishing with eDNA samples collected from the same reaches. Further, we explore whether the number of eDNA monitoring ‘reads’ for species at a site may provide an approximate (semi-quantitative) indication of their ‘near field’ relative abundance based on one-pass electrofishing captures. Results indicated that while some aspects of the methodology require fine-tuning, eDNA sampling shows substantial promise for complimenting state of the environment (SOE) reporting for describing fish diversity in wadeable streams. The use of aquatic eDNA monitoring to provide a cost-effective indication of broader catchment scale biodiversity (e.g. birds and exotic pests) in wadeable and non-wadeable streams is also discussed.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2021.1905672","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48732316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Antarctica’s extreme nature presents limitations to conducting the type of long-term or broad-scale studies necessary for understanding changes in community composition. In this paper, we evaluate the potential for the use of environmental DNA (eDNA) methods in expanding scientific research efforts for biodiversity monitoring and conservation genetics in Antarctica. Through a systematic literature review, we identify that most Antarctic eDNA studies have focused on microbial metabarcoding using samples from soil, sediment, snow, and water. Few eDNA studies in Antarctica have focused on vertebrate biodiversity or population genetics, but we highlight several examples that have effectively and creatively used eDNA to study vertebrates. We highlight the potential for the use of portable sequencing technologies in the future of Antarctic eDNA research. We conclude that eDNA could be a valuable tool for researchers in their efforts to assess, monitor, and conserve biodiversity in the Antarctic.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2021.1900299","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47624515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We experimentally examined the effects of visitor presence on the behaviour and stress physiology of little penguins at Wellington Zoo, New Zealand. The two treatments were: (1) Visitor presence – the exhibit was open to visitors; and (2) Visitor absence – the exhibit was closed to visitors. We found that when the exhibit was closed to visitors, the percentage of penguins observed close to the visitor viewing pier increased from about 1% to 9%, but there was little effect on other behaviours and faecal glucocorticoid metabolite concentrations. This result of increased avoidance of the visitor viewing pier when the exhibit was open to visitors suggests close visitor contact, particularly from above, may be fear-provoking for these penguins. We conclude that designing enclosures to allow close viewing proximity of visitors, such as visitors looming over the pool, may be futile in improving visitor experience, since this species of penguins is likely to avoid these types of viewing areas when visitors are present. Visitors positioned close to and above penguins may be particularly problematic since visitors in this position may be perceived as threatening.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2021.1896560","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42719533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to estimate the number and biomass of eels supported by Southland duck ponds to highlight the value of hunter-created wetlands as eel habitat. Eel population surveys were conducted in 56 duck ponds located on private agricultural land across Southland. Shortfin eels were found in 28 ponds with an average population size of 22 and biomass of 9.3 kg. Longfin eels were found in 26 ponds with an average population size of nine and biomass of 7.6 kg. Estimates indicate there are 7,013 ± (1761) duck ponds in Southland and they collectively support 36,000 shortfin eels weighing 15,500 kg and 60,000 longfin eels weighing 53,000 kg.

We used the Smith Root DNA sampler backpack with two types of filters (1.2 and 5 µm pores), to filter water and capture eDNA, and used quantitative polymerase chain reactions (qPCR), and digital droplet PCR (ddPCR) to measure the amount of G. affinis DNA collected by the two filter sizes. We also used high throughput (Illumina MiSeq) sequencing (HTS) to detect G. affinis. Results from the two PCR methods and the high throughput sequencing were compared to hand net counts of G. affinis. We found that all three methods were equally successful at detecting G. affinis when four replicates were taken from each site, but that sensitivity over all replicates was ddPCR > qPCR > HTS. We conclude that the use of environmental DNA to detect the presence of G. affinis is a useful tool to assist in mapping the distribution of G. affinis and will aid in the control of this invasive species.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2020.1858880","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49017597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monitoring populations can provide useful information to inform conservation action. Kaipatiki, Auckland, contains approximately 450 ha of indigenous forest, scrub and wetland ecosystems. Pest-controlled reserves are important for supporting avian biodiversity, however, this has not been measured extensively over time across Kaipatiki. An established method to measure changes in avian biodiversity and numbers over time is using stationary point-counts. Using this method, bird counts were conducted in 19 reserves during three consecutive breeding season periods (2016–2018). We also conducted correlative analyses on mammalian predator and bird abundance within Kaipatiki to examine these relationships. Mixed modelling statistical analyses suggested significantly higher numbers of individual birds of all detected species in 2018 than both 2016 and 2017. Tūī, silvereye, grey warbler and fantail were the most common native species observed. Further, rat relative abundance had a significant negative relationship with bird abundance. Ongoing bird counts across Kaipatiki will help provide robust long-term data allowing reliable analyses of population trends and avian species dynamics. These data should be subjected to correlative analyses alongside mammalian predator control data in each reserve. This will enable us to gauge predator control effectiveness in terms of native bird number changes.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2020.1833948","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44801309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We quantified the relative frequency of behaviours and diversity of food items for the species during autumn and winter to help refine the current management of the species. We also collected information on the availability of one of their main foods: niau (Rhopalostylis baueri) fruits. Parakeets fed on fruit pulp and seeds of eight plant species. Niau fruits represented 44% of total feeding bouts indicating that this is an important food item during the autumn-winter period. The most common behavioural state during our observations was feeding (30% of behavioural states). Our estimate of niau fruit availability in the core area of Tasman parakeet occurrence indicates approximately 1.2 million fruits during the peak of fruiting in spring. Tasman parakeets are generalists, but niau fruits represent an abundant and important resource. Although niau are common and produce large quantities of fruit, introduced rats (Rattus spp.), potentially represent significant competitors to Tasman parakeets, because they also feed on niau fruits. Ongoing control of rats is thus critical to maintain large quantities of native fruits to sustain a growing population of Tasman parakeets.","PeriodicalId":19208,"journal":{"name":"New Zealand Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03014223.2020.1839515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42781248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
