Growth rate, ultrastructure and sediment contribution of Halimeda incrassata and Halimeda monile, Nonsuch and Falmouth Bays, Antigua, W.I.

Coral Reefs, 1988
Halimeda incrassata and Halimeda monile, the two dominant rhipsalian Halimeda, were evaluated behind a bank barrier reef, in a fringing reef lagoon and in an open lagoon. Growth was calculated in number of segments, weight of segments and turnover rate.

Halimeda bioherms of the eastern Java Sea, Indonesia

Geology, 1987
Extensive areas of coalescing bioherms composed primarily of disarticulated Halimeda plates occur on a large carbonate bank (Kalukalukuang Bank) located 50 to 70 km east of the central Sunda Shelf margin (eastern Java Sea, Indonesia). High-resolution seismic profiles suggest that these features attain maximum thicknesses of up to 52 m above an ...

Sym-triazine derivative from Halimeda xishaensis

Phytochemistry, 1998
A 1,3,5-sym-triazine derivative, halimedin, was isolated from the alga, Halimeda xishaensis. Its structure was established by spectroscopic methods and X-ray crystallographic diffraction analvsis.

Halimeda bioherms of the northern Great Barrier Reef

Coral Reefs, 1988
The reefless tract directly behind the ribbon reefs on the outer shelf off Cooktown supports a luxuriant growth of Halimeda that, during the Holocene, has developed into bioherms. These mounded biodies of unconsolidated sediment have formed banks that vary in height between 2 and 20 m.

Ultrastructure of the spermatozoid in Halimeda tuna (chlorophyceae)

Gamete Research, 1979
AbstractThe mature Halimeda tuna spermatozoid was studied under the electron microscope. It is pear‐shaped and biflagellate. The nucleus is an uncondensed structure except for a few opaque (chromatin) aggregations and shows a rounded profile. The endoplasmic reticulum is a rather well‐developed system of rough cisternae engaged in synthesis and storage

Halimeda: paleontological record and palaeoenvironmental significance

Coral Reefs, 1988
Udoteacean algae, identical or related to Halimeda, have been recorded in shallow-marine carbonate rocks since Upper Triassic. About 30 species have been described, most of which occur in Lower Cretaceous shelf carbonates. These species are conventionally attributed to four “genera” (Arabicodium Elliott, Boueina Toula, Halimeda Lamouroux ...

Ultrastructure of the siphonaceous green alga Halimeda cuneata, with emphasis on the cytoskeleton

Micron, 2010
Cytoplasm streaming is a fundamental process for the transport of molecules and organelles in plant cells. In vegetative filaments of the coenocytic green alga, Halimeda cuneata Hering, the spatial organisation of microtubules in the cytoplasmic layer, was observed under transmission electron microscopy.

Systematics of the genus Halimeda (Bryopsidales, Chlorophyta) in Brazil including the description of Halimeda jolyana sp. nov.

Phycologia, 2017
Abstract: The genus Halimeda has a wide geographic distribution in tropical to subtropical regions of the world. Molecular studies have uncovered cryptic and pseudocryptic species as well as strong biogeographic signals in phylogenies. To date, the diversity of Brazilian Bryopsidales has been studied from only a morphological perspective.
