Coralline red algae from the New Zealand region were investigated in a study focused on documenting regional diversity. We present multi-gene analysis using sequence data obtained for four genes (nSSU, psaA, psbA, rbcL) 68 samples. The revealed cryptic diversity at both genus and species levels, confirming providing further evidence of problems with current taxonomic concepts Corallinophycidae. In addition, new Corallinapetra novaezelandiae gen. et sp. nov. is erected material northern...
The genetic diversity of the green algal genus Ulva sensu lato in New Zealand region was surveyed, examining rbcL sequences 581 samples from a wide geographical range. Twenty-four genetically distinct taxa were discovered waters, belonging to three genera–Ulva (19 species), Umbraulva (four species) and Gemina (one species). Of 19 species reported here, 13 could be identified level based on morphological data. remaining six cannot currently assigned known groups due lack close homology with...

Genetic diversity in Undaria pinnatifida (Laminariales, Phaeophyceae) deduced from mitochondria genes – origins succession of introduced populations. Phycologia 45: 687–695. DOI: 10.2216/05-66.1To elucidate the genetic brown alga native populations worldwide, to discuss transoceanic introduction processes, we investigated haplotype divergence mitochondrial loci coding region cox3 noncoding...
Coralline algae (Corallinophycideae) are calcifying red that foundation species in euphotic marine habitats globally. In recent years, corallines have received increasing attention due to their vulnerability global climate change, particular ocean acidification and warming, because of the range ecological functions coralline provide, including provisioning habitat, influencing settlement invertebrate other algal species, stabilising reef structures. Many roles perform, as well responses...
Abstract. The waters of Aotearoa New Zealand span over 4.2 million km2 the South Pacific Ocean and harbour a rich diversity seafloor-associated taxa. Due to immensity remoteness area, there are significant gaps in availability data that can be used quantify map distribution seafloor demersal biodiversity, limiting effective management. In this study, we describe development accessibility an online atlas seabed biodiversity aims fill these gaps. Species models were developed for 579 taxa...
When large volumes of macroalgae wash up on beaches, accumulate in coastal areas or within confined bays, there can be significant local impacts. Blooms are being reported throughout the world with increasing frequency estuarine and both temperate tropical regions. This review examines examples nuisance accumulations New Zealand, geographic seasonal distribution algal records, available data impacts communities, including human activities, considers some factors that may lead to excessive...
Herbaria and natural history collections (NHC) are critical to the practice of taxonomy have potential serve as sources data for biodiversity conservation. They repositories vital reference specimens, enabling species be studied their distribution in space time documented analysed, well development hypotheses about relationships. The herbarium Museum New Zealand Te Papa Tongarewa (WELT) contains scientifically historically significant marine macroalgal collections, including type primarily...
Abstract The recognition of non-indigenous marine macroalgae in New Zealand and the potential pathways vectors contributing to their arrival were discussed by Nancy Adams 1983 along with a list 14 species she considered be “possibly naturalised”. In following 38 years many more have been identified as non-indigenous, few which become widespread invasive around Zealand. We present an updated 61 taxa that we consider introduced archipelago, highlight range issues associated species,...
To support ongoing marine spatial planning in New Zealand, a numerical environmental classification using Gradient Forest models was developed broad suite of biotic and high-resolution predictor variables. modeling uses species distribution data to control the selection, weighting transformation predictors maximise their correlation with compositional turnover. A total 630,997 records (39,766 unique locations) 1,716 taxa living on or near seafloor were used inform 20 gridded variables...
New Zealand has a rich and diverse macroalgal flora that been studied since James Cook’s first voyage to in 1769. The region ranges from cool temperate seas at southerly latitudes to subtropical waters the north. Here we review the history of phycological research since 1900, current status taxonomy, ecology, physiology seaweed uses including aquaculture and extracts. Some 770 species of seaweed are known to Zealand, which 22 are alien. Few taxa have received monographic...
The macroalgal flora associated with rhodolith beds in the Bay of Islands, northeastern North Island, was investigated as part first detailed study subtidal rhodoliths New Zealand. differed their physical characteristics and dominant rhodolith-forming species present, one bed clear water predominantly Lithothamnion crispatum rhodoliths, other turbid water, Sporolithon durum covered by fine sediments. One hundred three taxa were identified (12 green, 24 brown 67 red algae), similar numbers...
The present dataset is a compilation of georeferenced occurrences asteroids (Echinodermata: Asteroidea) in the Southern Ocean. Occurrence data south 45°S latitude were mined from various sources together with information regarding taxonomy, sampling source and sites when available. Records 1872 to 2016 thoroughly checked ensure quality that reaches total 13,840 4,580 unique events. Information reproductive strategy (brooders vs. broadcasters) 63 species also made This represents most...
The kelp Lessonia variegata J. Agardh (Lessoniaceae) is a potential aquaculture target for bioactive compounds. We investigated the control and management of gametogenesis, settlement retention sporophytes on various culture strings, upscaling string field trials. In laboratory we held gametophytes at low light conditions 2.5 months before altering to stimulate them into next part life cycle. Settlement development was highest Korean string, followed by Builders Line, however after...
Abstract Polysiphonia morrowii , a species native to the North Pacific, is believed have been introduced Chile, Turkey, Italy and France. This was first recorded from New Zealand in 2011, based on collections made 2004 two sites South Island, but no commentary provided distribution or characteristics of material collected. In 2009, as part study macroalgae associated with soft sediment habitats Zealand, several samples P. were collected Otago Harbour, location already known host 17...
Abstract Rhodoliths are recognised as providing critical ecosystem services in nearshore systems through habitat provision. We tested the influence of rhodolith hosts and on diversity composition sessile motile invertebrates found associated with two species rhodolith. Investigations cryptofauna were undertaken at three beds within Bay Islands, northern New Zealand. Lithothamnion crispatum , which was smaller overall size, had less free space a internal volume than Sporolithon sp., provided...
Abstract Biogenic habitats are foundational for species assemblages and drive a range of ecosystem functions. The Hauraki Gulf/Tiikapa Moana is the most intensively used coastal area in Aotearoa/New Zealand, decades commercial fishing, sedimentation industrialization have degraded biogenic Gulf. In response, marine spatial plan ‘Sea Change’ includes proposals to create new extend existing protected areas (MPAs) restrict open mobile bottom‐impact fishing methods conserve help recovery...
A molecular phylogenetic analysis of the genus Hippasteria, rooted against Evoplosoma, has provided basis for taxonomic revisions and insight into biogeography a widely occurring, cold-water group corallivorous asteroids. Herein, we describe three new species, Hippasteria mcknighti sp. nov., muscipula tiburoni from deep-water settings. Additionally, in light changes, further elaborate on distribution data multiple species. Range extensions phrygiana californica are included. Discussions...
