Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

Modeling of the geographical distribution of two forest‐forming fucoids in the Strait–Alboran demarcation (southern Iberian Peninsula): Implications for conservation and restoration

Journal of Phycology, EarlyView.
Abstract Marine forests formed by canopy‐forming brown algae of the former Cystoseira complex are key habitat‐forming components of Mediterranean coastal ecosystems, supporting biodiversity and multiple ecosystem functions. However, many populations have declined in recent decades due to increasing anthropogenic pressures and climate change, raising ...

Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

Journal of Phycology, EarlyView.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Carrageenan catabolism is encoded by a complex regulon in marine heterotrophic bacteria

Nature Communications, 2017
Carrageenans, major cell wall polysaccharides of red macroalgae, are metabolised by marine heterotrophic bacteria through unclear mechanisms. Here, the authors identify an unusual polysaccharide-utilization locus encoding carrageenan catabolism in a ...

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

New Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

Potentialities of Argentine marine macroalgae

Marine and Fishery Sciences, 2020
En la extensa costa argentina se encuentran numerosas especies de macroalgas de importancia a nivel mundial. En el presente trabajo se debaten los estudios más relevantes publicados hasta la fecha sobre los usos de las algas marinas y se mencionan las investigaciones argentinas con el objetivo de evaluar el estado de conocimiento del recurso.

The genus Arthrocardia (Corallinales, Rhodophyta) in New Zealand: Description of three new species

Phycological Research, EarlyView.
SUMMARY Three new species of the coralline algal genus Arthrocardia (Corallinophycidae, Rhodophyta) are described from New Zealand: A. meridionalis, A. perplexa, and A. robusta. These species are difficult to distinguish based on morphoanatomical characters alone and require molecular sequence data for reliable identification.
