A simple substrate to produce the tropical epiphytic algae Hypnea pseudomusciformis

open access: yesAquacultural Engineering, 2020
Abstract The seaweeds Hypnea spp have been used as a direct human food, for carrageenan extraction, and exploitation of chemical compounds of interest. Nevertheless, its culture is still undeveloped because of difficulties in managing the epiphytic habit.

Circadian Oscillations in Branchlet Angle and Irradiance‐Dependent Acclimation in Chara braunii Under Continuous Light

open access: yesPlant Direct, Volume 10, Issue 10, October 2026.
ABSTRACT Endogenous biological rhythms are central to temporal organization in land plants, yet their evolutionary origins in streptophyte algae remain unresolved. We investigated whether rhythmic morpho‐physiological processes in Chara braunii are consistent with endogenous regulation and how continuous light intensity modulates these responses. In C.

A Qualitative Study of Epiphytic Algae (Diatom) on Some Aquatic Plants in Al-Auda Marshes Within Maysan Province / Southern Iraq

open access: yesمجلة بغداد للعلوم, 2015
The study conducted on the compositions of epiphytic diatoms on three taxa of aquatic plants were selected (Phragmites australis Trin ex stand , Ceratophyllum demersum L. and Typha domengensis Pers) in three sites within Al-Auda Marsh, from autumn 2013

Antagonistic Effect of Epiphytic Bacteria from Marine Algae, Southeastern India

open access: yesPakistan Journal of Biological Sciences, 2013
Aim of this study was to evaluate the antagonistic potential of epibiotic bacteria from seaweeds, Ulva lactuca, Dictyota dichotoma and Padina tetrastromatica against some potent human pathogens. The epibiotic bacteria of Ulva lactuca shows higher level of inhibition properties than the other species.

Seasonal distribution of epiphytic algae on natural and artificial substrates and the relationship between their biomass and water physico-chemical properties in Anzali Lagoon

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2005
We studied epiphytic algae in Anzali Lagoon in Guilan Province from September 2000 to August 2001. The algae were removed from natural and artificial substrates and their biomass were determined using Sedgwick - Rafter Cell and Olympus microscope ...

Leveraging Species Associations Patterns of Macroalgae in Wrack to Predict Their Spatial Distribution

open access: yesDiversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Species associations are increasingly recognized as an effective way to improve species distribution model (SDM) predictions by integrating biotic and abiotic information that is difficult to measure in situ. This approach appears promising for monitoring communities where biodiversity and environmental data are sparse or limited.

Diversity of Epiphytic Subaerial Algal Communities in Bangkok, Thailand, and Their Potential Bioindicator with Air Pollution

open access: yesDiversity
Epiphytic subaerial algae represent an assemblage of micro-organisms widely distributed in terrestrial environments, including urban environments. Urban habitats present many challenges for the survival of photosynthetic micro-organisms, yet many species

Seasonal occurrences of epiphytic algae on the commercially cultivated red alga Kappaphycus alvarezii (Solieriaceae, Gigartinales, Rhodophyta) [PDF]

open access: yesJournal of Applied Phycology, 2006
Common problems faced in farming of the red algal genus Kappaphycus/Eucheuma are “ice-ice disease” and the occurrence of epiphytes. Considerable work has been documented on “ice-ice disease” and it's mode of infection but limited information is available on the emergence of epiphytes.
