A new locality of Ulva intestinalis was found near Krąplewo in the River Samica Stęszewska located in the Wielkopolski National Park region (Wielkopolska). On the basis of Carlson's index ranges, waters of the Samica Stęszewska river were qualified as eutrophic. In the river single thalluses of U. intestinalis which appeared by its banks were observed. The presence of this Ulva species thalluse...

The green marine macroalgae of the class Ulvophyceae (Ulvophytes) are common algae distributed worldwide particularly in intertidal areas, which play a key role in aquatic ecosystems. They are potentially valuable resources for food, animal feed and fuel but can also cause massive nuisance blooms. Members of Ulvaceae, like many other seaweeds, harbour a rich diversity of epiphytic bacteria with...

Ulva intestinalis and Ulva compressa are two bloom-forming morphologically-cryptic species of green seaweeds widely accepted as cosmopolitan in distribution. Previous studies have shown that these are two distinct species that exhibit great morphological plasticity with changing seawater salinity. Here we present a phylogeographic assessment of tubular Ulva that we considered belonging to this ...

The lipid composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, and Ulva prolifera) grown in fish pond aquaculture systems was studied. In particular, the overall fatty acid (FA) profile and the FA profile of each main lipid class found in these seaweed species were thoroughly analyzed. It was found that every seaweed had a sp...

Bu çalışmada, yeşil alglerden Ulva intestinalis türünün ekolojik özellikleri ile besin kompozisyonundaki değişimin belirlenmesi amaçlanmıştır. Çalışma materyali Sinop kıyıları boyunca seçilen dört farklı noktadan mevsimsel olarak toplanmıştır. Yapılan analizler sonunda mevsimler ve istasyonlar arasında istatistiksel önemli farklılıklar (P

Variations in protein, lipid, carbohydrate and astaxanthin content of Enteromorpha intestinalis, Ulva lactuca and Catenella repens were documented over a 10 months period from September 2007 to June 2008. The macroalgal species were collected from six sampling stations of Indian Sundarbans, a Gangetic delta at the apex of Bay of Bengal. On dry weight basis, the protein content varied from 4.15±...

Differential tolerance of low salinity, competition for nitrogen (N), and facilitation by altering N supply all may act to determine the pattern of seasonal succession of Enteromorpha intestinalis (L.) Link and Ulva expansa (Setch) S. and G. in estuaries and lagoons of southern California. Low salinity negatively affected both of these algae. However, when N was in sufficient supply, salinities...

The antioxidant activity, contents of total phenolics and flavonoids were quantified in the methanolic extracts of four Ulva species (Ulva clathrata (Roth) C.Agardh, Ulva linza Linnaeus, Ulva flexuosa Wulfen and Ulva intestinalis Linnaeus) grown at different parts of northern coasts of the Persian Gulf in south of Iran. The seaweeds were collected from Dayyer, Taheri and Northern Ouli coasts in...
