New Algae Discoveries in the North Pacific and Okhotsk Sea
Researchers at the National Marine Biology Scientific Center named after AV. Zhirmunsky, affiliated with FEB RAS, have identified four previously unknown edible algae species in the Sea of Okhotsk and the northwestern Pacific Ocean. The discovery was disclosed to socialbites.ca by the Russian Ministry of Education and Science.
All four species belong to the genus Devaleraea within the family Palmariaceae. This small red-algae group is recognized for producing biologically active substances and lectin, a compound used in diagnosing several diseases. Devaleraea species serve as human food and also nourish the abalone mollusk. For both roles, palmarian algae are harvested from natural kelp beds and cultivated on aquaculture farms to ensure steady supplies.
“We have identified four species of the genus Devaleraea that are new to science. This matters because precise information about species composition is essential to understanding how coastal flora forms and how communities adapt to environmental stressors”, stated Anna Skriptsova, Senior Researcher and Head of the Autotrophic Organisms Laboratory at NSCMB FEB RAS, during an interview with socialbites.ca.
The work tracking the algae’s species composition supports the primary aim of biology: to inventory the algae living in Russian waters and across the World Ocean. Detailed descriptions help clarify where these species are found and how they interact with their environment.
By documenting these specimens in depth, scientists revisited their knowledge about where the organisms occur, their ecological preferences, and the temperature ranges that support growth and reproduction. The research also yielded substantial data on the DNA regions of Devaleraea found along Russia’s coast. This genetic information enables accurate identification not only by taxonomists but also by researchers using genomic data to study the functioning and dynamics of shore communities. Such insights illuminate the role palmarian algae play in temperate aquatic ecosystems and their response to climate-related changes.
The findings expand the baseline knowledge of marine biodiversity in the region and have potential implications for coastal management, fisheries, and conservation strategies. As researchers explore the ecological roles of Devaleraea species, they emphasize the importance of preserving natural habitats while supporting responsible cultivation. The work demonstrates how modern genetics and classic taxonomy together deepen our understanding of seaweed diversity and the processes shaping coastal ecosystems. The collaboration underscores the value of ongoing field surveys, specimen collection, and genetic analysis for monitoring biodiversity and ecosystem health in Canada, the United States, and neighboring waters.
