Abstract:

The relationship between benthic macroalgae and associated polychaetes was studied monthly from October 2014 to October 2015 along the Alexandria coast, Egypt. A total of 56 polychaete species were found among 28 macroalgal species, which belonging to green, brown and red algae. The red algae hosted pronouncedly higher number of polychaete species than the brown and green algae, particularly during winter and spring, while green algae were associated with higher number of polychaete species in January, April, August and October 2015. In contrast, the average count of polychaete individuals ass

Algae are the naturally produced food for fish in any aquatic ecosystem and an indicator of a productive pond. However, excess abundance of harmful algae can have detrimental effects on fish health.

Abstract:

Marine algae are an excellent source of novel lectins. The isolation of lectins from marine algae expands the diversity in structure and carbohydrate specificities of lectins isolated from other sources. Marine algal lectins have been reported to have antiviral, antitumor, and antibacterial activity. Lectins are typically isolated from marine algae by grinding the algal tissue with liquid nitrogen and extracting with buffer and alcohol. While this method produces higher yields, it may not be sustainable for large-scale production, because a large amount of biomass is required to produce a minu

Abstract:

The algal distribution in farmland depends on the plantation type and soil properties, therefore the present study was aimed to assess the diversity of algal community in soils of tea- and pineapple-plantation soils and to correlate the relationship between algae and soil parameters. Soil samples were collected from tea- and pineapple-plantations every month from April 2022 to May 2023. The soil and algal samples were analyzed by appropriate standard methods. Tea plantation soil was clay loam while pineapple plantation soil was sandy loam. The soil samples from study sites were slightly acidic

Abstract:

Algae are vital to aquatic ecosystems, with their structure and abundance influencing ecological health. However, automated detection in real water samples is hindered by complex backgrounds, species diversity, and size variations. Traditional methods are deemed costly and species-specific, leading to deep learning adoption. Current studies rely on CNN-based models and limited datasets. To improve the detection accuracy of multiple algal species in real, complex backgrounds, this study collected multi-species algae samples from actual water environments and implemented an integrated Transforme

Abstract:

All marine communities in Greenland are experiencing rapid environmental change, and to understand the effects on those structured by seaweeds, baseline records are vital. The kelp and coralline algae habitats along Greenland’s coastlines are rarely studied, and we fill this knowledge gap for the area around Nuuk, west Greenland. Using subtidal swath surveys, photo-quadrats, and grab samples, we characterised the diversity of floral and faunal assemblages in kelp forests and coralline algae beds. The most abundant herbivore assemblages and the most diverse communities occur in the interstitial

Abstract:

Microbes influence ecological processes, including the dynamics and health of macro-organisms and their interactions with other species. In coral reefs, microbes mediate negative effects of algae on corals when corals are in contact with algae. However, it is unknown whether these effects extend to larger spatial scales, such as at sites with high algal densities. We investigated how local algal contact and site-level macroalgal cover influenced coral microbial communities in a field study at two islands in French Polynesia, Mo'orea and Mangareva. At 5 sites at each island, we sampled prokaryo
