In Aotearoa New Zealand, there is little planning to provide future accommodation space for estuaries. A complex knot of policies and plans, and accompanying poor implementation also affect ecological sustainability. We examine these issues for Brooklands Lagoon/Te Riu o Te Aika Kawa, a tidal lagoon northeast of Christchurch/Ōtautahi. It is within the takiwā of Ngāi Tahu iwi and Ngāi Tūāhuriri hapū, and the jurisdictions of Christchurch City Council and Environment Canterbury. The estuary is influenced by three rivers, and surrounding land use is managed under three different statutory resource management plans, along with several non-regulatory strategies and organisational management plans. However, these plans are poorly integrated and estuarine ecological health is compromised. The incoming tide of resource management and local government reform will add complexity, but also an opportunity to accommodate and enhance the estuary as a blue carbon sink, and to restore cultural and ecological values. This requires specific recognition of estuaries in the proposed managed retreat and spatial planning laws, and within the replacement resource management statute. Legal recognition of Indigenous customary rights could also produce novel governance models to improve management.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"56 1","pages":"312 - 332"},"PeriodicalIF":1.6,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49209079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the distribution, invasion history, abundance and population structure were investigated for C. japonica across the North Island of New Zealand. This was done using various distribution data available, trapping across several sites and interviews with commercial fishermen. Charybdis japonica was detected in the previously uninvaded Tauranga, Ohiwa, Hokianga, Manukau Harbours and Great Barrier Island. The rate of spread for C. japonica is continuous, with harbours or estuaries hundreds of kilometres apart having detections every two to three years. Population abundances reported by commercial fishermen constantly increased, with no signs of stabilisation or decrease. Catches were male-biased, with female abundance varying seasonally. Several possible pathways and vectors may be responsible for this spread, including shipping and aquaculture, on top of dispersal of larvae by currents across the North Island. Further research is required to determine population sources, with findings providing important information for invasive species monitoring and management.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"57 1","pages":"518 - 534"},"PeriodicalIF":1.6,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46712611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major C fraction is in the dissolved organic matter (DOM) with multiple regulatory functions. Patagonian wetlands undergo changes in the water cycle due to climate warming and lower precipitation, causing shorter hydroperiods and reduced landscape connectivity with effects on C budgets. This study focuses on the optical characterisation of the DOM of an ephemeral wetland of North Patagonia. Along the hydroperiod the DOM showed optical signatures indicating terrestrial inputs, degradation and internal production. Dissolved organic carbon (DOC) concentration ranged between ∼4 and ∼9 mg L−1. The DOM pool displayed high molecular weight/size and aromatic fingerprints. Humic components C1 (microbial and/or vegetation derived) and C2 (soil/sediment) prevailed in the DOM, whereas the non-humic component C3 (from aquatic processes) increased from early spring. Experimental exposure to PAR + UVR produced slight changes in DOC and reduction in DOM molecular weight/size. The components showed distinctive photoreactivity/lability: C1 > C3 > C2. Along the hydroperiod the relative contribution of the humic vs. non-humic components (C1 and C3) determined the reactivity/lability of the DOM. In Fantasma pond, the DOM pool fluctuates in response to hydrology and degradation processes, and the alternance between dry and flooded periods determines C dynamics.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"57 1","pages":"480 - 494"},"PeriodicalIF":1.6,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44579621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trial aimed to restore seagrass at a more distant former site and tested the efficacy of transplant units ranging in size from small cores (5 or 9 × 0.01 m diameter cores placed within a 0.25 m2 plot) to larger entire plots (0.25 m2 or 0.5 m2). Seagrass was transplanted in winter when plants were dormant. Plant cover of transplanted and donor plots and light climate at both sites were monitored over a period of four years. All but one of the 24 units survived, and the plants began to spread after 12–18 months to eventually develop patches ranging in size from 5 to 68 m2. Seagrass recolonised all donor plots completely within 10 months. Results show that small cores and larger plots can both be used successfully to transplant and restore populations of Zostera muelleri with no long-lasting damage to donor meadows. However, use of small cores is recommended to minimise extractions and loss of transplanted material, and to simplify logistics.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"57 1","pages":"467 - 479"},"PeriodicalIF":1.6,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41732495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such activities can degrade the environment and disrupt the behaviour and natural function of organisms. A small population of bottlenose dolphins (Tursiops truncatus) is resident in Dusky Sound, New Zealand, a fjord with increasing human use. Dolphins, as top predators, play an important role within ecosystems and are at risk of long-term negative consequences from behavioural changes when exposed to high levels of vessel activity. A better understanding of the distribution of the dolphins in Dusky Sound would provide a framework for developing management within the fjord. Here we describe where dolphins were most frequently found, based on >40,000 km of photo-ID survey effort conducted over 10 years. Kernel density estimation revealed two large core areas that remained consistent over the duration of this study. This information could be used to determine areas within Dusky Sound where human activities around dolphins could be managed to avoid anthropogenically driven detrimental impacts. We suggest the following: (1) establish dolphin protection zones, (2) create a marine mammal sanctuary, (3) extend marine reserve boundaries, and/or (4) lower catch limits for fish within the fjord boundaries.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"57 1","pages":"411 - 424"},"PeriodicalIF":1.6,"publicationDate":"2022-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49558326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we recorded the associations between individual bleach-marked SSLs in the harbours of Mar del Plata (PM) and Puerto Quequén (PQ) on four different substrate types during four non-breeding seasons. We found that the association pattern differed between the harbours, with a well-differentiated social structure being evident in PM but very little social differentiation occurring in PQ. The observed social structure in PM may have resulted from passive habitat preference rather than genuine social behaviour, as the association pattern disappeared when SSLs moved to sandy beaches within the harbour. Given that these colonies are must-see tourist attractions but may have negative interactions with human activities, we recommend considering the association between SSLs and artificial habitats to design effective management strategies and reduce potential conflicts.","PeriodicalId":54720,"journal":{"name":"New Zealand Journal of Marine and Freshwater Research","volume":"57 1","pages":"395 - 410"},"PeriodicalIF":1.6,"publicationDate":"2022-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42481737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
