Antimicrobial activity of Iberian macroalgae

open access: yesScientia Marina, 2007
The antibacterial and antifungal activity of 82 marine macroalgae (18 Chlorophyceae, 25 Phaeophyceae and 39 Rhodophyceae) was studied to evaluate their potential for being used as natural preservatives in the cosmetic industry.

Non‐Fungi Diversity Present in Soil and Snow Impacted by Anthropogenic Activity in King George Island, Maritime Antarctica Using Metabarcoding Approach

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT The Antarctic Peninsula shows a fast‐rising temperature trend, increasing the risk of colonization by non‐native species, such as the invasive Poa annua. The “cryptic diversity” of largely unknown microscopic propagules in soil and snow poses a significant threat, as traditional morphological surveys are inadequate.

Nutritional status response of Daphania laevis and Moina micura from a tropical reservoir to different algal diets: Scenedesmus quadricauda and Ankistrodesmus gracilis

open access: yesBrazilian Journal of Biology
The accumulation of lipid reserves was investigated in two common cladoceran species typical of neotropical freshwaters. Experiments were performed in order to measure differential accumulation of lipid reserves in response to two algal diets, S ...

Chlorophyceae

open access: yes
Class Chlorophyceae The class Chlorophyceae, one of the three crown branches of green algae, includes morphologically and ecologically diverse organisms that occur mainly in freshwaters. The thallus morphology ranges from unicellular algae (with or without flagella) or simple colonies to branched or unbranched filaments, or even blade-like thalli ...

Macroalgae and Bivalve Interactions: A Review of Trophic and Feeding Studies to Assess the Contribution of Macroalgal Detritus to Bivalves

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT There is growing interest in the co‐culture of macroalgae and filter‐feeding bivalves due to anticipated trophic benefits that may enhance the productivity of both organisms. Detritus from cultured macroalgae has the potential to supplement bivalve diets, yet few studies have directly examined this relationship in co‐culture systems.

Amino Acids in the Natural Food Web of Global Fishponds: Way Forward for Precision Protein Feeding in Pond Cyprinid Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Natural food webs in freshwater pond ecosystems provide an important nutritional foundation for cyprinid aquaculture, yet information on their protein and amino acid composition remains fragmented. This review synthesized published data from 30 studies (1950–2026) reporting protein and indispensable amino acid (IAA) composition of freshwater ...
