Ulva ardreana: a new species replacing the invalid “Ulva bifrons”
botm, 2013Abstract The new species Ulva ardreana is here proposed to replace Ulva bifrons, an invalid name because no holotype was designated in the protologue. The new species consists of two to three distromatic blades arising from a short stipe, and it is easily distinguished from the other blade-like Ulva species in having a remarkable ...

Conspecificity of the model organism Ulva mutabilis and Ulva compressa (Ulvophyceae, Chlorophyta)
Journal of Phycology, 2018As one of the most abundant and ubiquitous representatives of marine and brackish coastal macrophytobenthos communities, the genus Ulva is not only an important primary producer but also of ecological and morphogenetic interest to many scientists. Ulva mutabilis

The removal efficiency for Cd (II) by the marine algae Ulva fasciata and Ulva lactuca was studied at different culture conditions. The maximum biosorption capacities were 8.353 and 8.804 mg g−1 dwt for U. fasciata and U. lactuca, respectively, at optimum conditions for each alga.

Anaerobic digestion of Ulva sp. 1. Relationship between Ulva composition and methanisation
Journal of Applied Phycology, 1997Ulva often represents the main component of mass algal growths, and its composition and degradability make it a relatively good methanisation substrate. In ‘green tides’ Ulva sp. from Brittany, the low content oflignin-type components (polyphloroglucinols: 1.3% dry weight), and the large hemicellulosic fraction (9% dry weight) favour the substrate's ...

The taxonomy ofUlva(Chlorophyceae) in the Netherlands
British Phycological Journal, 1981On the basis of 160 living samples from 26 different stations five Ulva species were distinguished, and described for the Netherlands coast, namely U. pseudocurvata nov. spec., U. curvata (Kutz.) De Toni, U. lactuca L., U. rigida C.Ag. and U. scandinavica Bliding.

Abstract The taxonomic relationships of Ulva californica, U. angusta and U. scagelii were evaluated through morphological studies of field and herbarium specimens, and through culture studies. These species show ecological, morphological and cytological similarities but differ in size, habit and distributions.

The effects of the nitrofuran furaltadone on Ulva lactuca
Chemosphere, 2011The use of pharmaceuticals in the food production industry as prophylatic and therapeutic agents is necessary to promote animal health, but may entail significant consequences to natural ecosystems, especially in the cases of overdosing and use of banned pharmaceuticals. The vast effects that antibiotics released into the environment have on non-target

IN the course of experiments on Ulva mutabilis1 some gametophytes are occasionally found forming swarmer which copulate neither with +-gametes nor with −-gametes. These swarmers are diploid, as revealed by cytological and genetical examination. They are biflagellate and of normal size, and otherwise they fully resemble normal gametes.
