OBSERVATIONS ON NAVICULA ULVACEA, A RARE FOLIOSE MARINE DIATOM¹

Journal of Phycology, 1979
ABSTRACT Navicula ulvacea (Berkeley ex Kütz.) P. T. Cleve, a marine colonial blade‐forming diatom originally discovered in Scotland was collected at North Rustico, Prince Edward Island, during winter 1971. It formed dense stands of Porphyra‐like fronds, ranging up to 60 mm long × 20 mm wide.

New Ulvaceae (Ulvophyceae, Chlorophyta) from mesophotic ecosystems across the Hawaiian Archipelago

Journal of Phycology, 2016
Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level.

New locality of macroalga Ulva prolifera (Ulvaceae) in the Wielkopolska Region

2011
New inland locality of Ulva prolifera O. F. Müller [=Enteromorpha prolifera (O. F. Müller) J. Agardh, Enteromorpha salina Kützing] was found in flowing pond in the Kopla valley, near Tulce country (Wielkopolska Region, locality coordinates: 52o20′35″N; 17o04′40″E). Macroalga thallus had been watched since May till August 2008. U.

SYSTEMATICS OF ULVACEAE (ULVOPHYCEAE, CHLOROPHYTA) USING NUCLEAR AND CHLOROPLAST DNA SEQUENCES

Journal of Phycology, 2000
Ulvaceae are morphologically simple, cosmopolitan green macroalgae. Family members, particularly species of Ulva and Enteromorpha, are prevalent in coastal ecosystems and responsible for “green tide” events around the world. Little is known about the evolutionary history of Ulvaceae.

First report of Chloropelta caespitosa (Ulvaceae, Ulvales, Ulvophyceae) in Japan*

Phycological Research, 1996
SUMMARY Chloropelta caespitosa Tanner was found in Nagasaki Prefecture, in western Japan. This is the first record of this species in Japan and the western Pacific. Morphology and early development in culture corresponded with the original description of this species. Reproduction is by asexual quadriflagellate (rarely biflagetlate) zoospores.

New Microsatellite Markers for Ulva Intestinalis (Chlorophyta) and The Transferability of Markers Across Species of Ulvaceae

Phycologia, 2008
Abstract Macroalgal blooms are a growing environmental problem in eutrophicated coastal ecosystems. Members of the green algal genus Ulva are significant contributors to blooms, which are typically dominated by only one of several co-occurring opportunistic species.

Green seaweed Enteromorpha compressa ( Chlorophyta , Ulvaceae ) derived sulphated polysaccharides inhibit herpes simplex virus

International Journal of Biological Macromolecules, 2017
The herpes simplex virus (HSV) diseases represent a relevant medical and social problem due to their communicability and recurrence following latency. The green algae are rich source of polysaccharides referred to as ulvans, reported as being biologically and pharmacologically active.

A New Observation of Ulva Pilifera (Ulvaceae, Chlorophyta) from the Freshwater Habitat of Türkiye

Acta Botanica Hungarica
The distribution and frequency of Ulva , a cosmopolitan genus, in aquatic systems are increasingly expanding due to global warming and anthropogenic influences. In contrast to their widespread distribution in marine environments, information on their ecology and distribution in freshwater ...

OCCURRENCE OF MACROALGAE FROM THE ULVA GENERA (ULVACEAE; CHLOROPHYTA) IN THE WIELKOPOLSKA REGION

2011
The work presents the specification of the reports from the appearance of species from Ulva genera (Ulvaceae, Chlorophyta) in the Wielkopolska region. The stands of the three species (Ulva compressa, U. intestinalis and U. prolifera) were marked on the map of the region in the ATPOL squares sequence.
