The endemic kelp Lessonia corrugata is being pushed above its thermal limits in an ocean warming hotspot

open access: yesJournal of Phycology, Volume 60, Issue 2, Page 503-516, April 2024.
Abstract Kelps are in global decline due to climate change, which includes ocean warming. To identify vulnerable species, we need to identify their tolerances to increasing temperatures and determine whether tolerances are altered by co‐occurring drivers such as inorganic nutrient levels. This is particularly important for those species with restricted

Loss of canopy-forming algal richness and coverage in the northern Adriatic Sea

open access: yesEcological Indicators, 2021
Canopy-forming macroalgae, especially those belonging to the order Fucales, are creating the so-called brown algal forests that are considered amongst the most productive assemblages in the shallow coastal area.

Air‐sea carbon dioxide equilibrium: Will it be possible to use seaweeds for carbon removal offsets?

open access: yesJournal of Phycology, Volume 60, Issue 1, Page 4-14, February 2024.
Abstract To limit global warming below 2°C by 2100, we must drastically reduce greenhouse gas emissions and additionally remove ~100–900 Gt CO2 from the atmosphere (carbon dioxide removal, CDR) to compensate for unavoidable emissions. Seaweeds (marine macroalgae) naturally grow in coastal regions worldwide where they are crucial for primary production ...

Restoration of a Canopy-Forming Alga Based on Recruitment Enhancement: Methods and Long-Term Success Assessment

open access: yesFrontiers in Plant Science, 2018
Marine forests dominated by macroalgae have experienced noticeable regression along some temperate and subpolar rocky shores. Along continuously disturbed shores, where natural recovery is extremely difficult, these forests are often permanently replaced

SEASONALITY AND SPECIES COMPOSITION IN THE BENTHIC ALGAE OF CACIQUE REEF FLAT, CARIBBEAN COAST OF PANAMA

open access: yesTecnociencia, 2006
    A one year study (April 1998 to May 1999) was conducted on the Cacique reef flat in the Caribbean coast of Panama. Of 49 species of benthic macroalgae encountered, 17 (35%) were Chlorophyceae, 13 (26%) Phaeophyceae and 21 (43%) Rhodophyceae.

Taxonomic revision of Sargassum sect. Acanthocarpicae (Fucales, Phaeophyceae)

open access: yesTAXON, 2010
AbstractSargassum is one of the morphologically most complex phaeophyceaen genera, and is divided into subgenera, sections, subsections, series and species groups based on highly polymorphic characters. Recent DNA analyses have highlighted incongruities in the traditional classification of the genus and especially within Sargassum subg. Sargassum sect.

Decline and local extinction of Fucales in French Riviera: the harbinger of future extinctions?

open access: yesMediterranean Marine Science, 2014
The French Riviera is one of the Mediterranean areas that has been longest and most thoroughly impacted by human activities. Fucales are long-lived, large-sized brown algae that constitute a good model for studying human impact on species diversity. We gathered all historical data (literature and herbarium vouchers), since the early 19th century, to ...
