Light limitation and water velocity modify the impacts of simulated marine heatwaves on juvenile giant kelp Open
Coastal regions are complex habitats, where multiple natural and anthropogenic drivers can interact to affect the survival and growth of marine organisms. The giant kelp Macrocystis pyrifera is sensitive to increasing seawater temperatures…

Quantifying indigenous kelp contributions to New Zealand’s deep-sea carbon sinks Open
Anthropogenic activities have caused an increase in greenhouse gas emissions, leading to the alarming rate of global temperature increase and associated climate change impacts. Due to these challenges, nature-based solutions for capturing …

Development and validation of five native Aotearoa New Zealand genera-specific large brown macroalgal eDNA ddPCR assays Open
Environmental DNA is a rapidly growing methodology for ecological studies, leading to an increase in innovative techniques, such as the droplet-digital PCR (ddPCR), that can quantify and target DNA at a high rate of sensitivity for eDNA st…

Marine heatwave intensity and duration negatively affect growth in young sporophytes of the giant kelp Macrocystis pyrifera Open
Kelp forests are productive and biodiverse ecosystems with high ecological, cultural, and economic importance. However, the high sensitivity of kelp to water temperature means that these ecosystems are vulnerable to marine heatwaves (MHWs)…

Quantifying pigment content in crustose coralline algae using hyperspectral imaging: A case study with <i>Tethysphytum antarcticum</i> (Ross Sea, Antarctica) Open
Crustose coralline algae (CCA) are a highly diverse group of habitat‐forming, calcifying red macroalgae (Rhodophyta) with unique adaptations to diverse irradiance regimes. A distinctive CCA phenotype adaptation, which allows them to maximi…

Marine macroalgae of the Balleny Islands and Ross Sea Open
The macroalgae of the Balleny Islands (66°15′S–67°35′S and 162°30′E–165°00′E) have been infrequently collected and the flora remains poorly known. This chain of islands is located on the edge of the Antarctic Circle in the northern Ross Se…

Resurrection of the Family Grateloupiaceae Emend. (Halymeniales, Rhodophyta) Based on a Multigene Phylogeny and Comparative Reproductive Morphology Open
The marine red algal order Halymeniales currently includes two families, the Halymeniaceae and Tsengiaceae, and consist of 38 genera and about 358 species. Phylogenetic analyses on specific taxa of the order are common, but not comprehensi…

Macroalgal assemblages as indicators of the ecological status of marine coastal systems: A review Open
Macroalgae have been utilized as biological indicators of ecosystem health in many monitoring programs worldwide. These programs have utilized various methods to quantify macroalgal community structures. The aim of this study was to provid…

Macroalgae of the Balleny Islands and western Ross Sea, Southern Ocean Open
The known macroalgal flora of the Balleny Islands, Southern Ocean, has more than doubled as a result of expeditions to the area over the past 8 years and their subsequent study is reported here. The samples collected as part of a benthic s…
