THE SYSTEMATIC POSITION OF THE FUCALES [PDF]
T HE Fucales are probably the most widely distributed and the most abundant of all the brown algae. They have certainly reached the highest level of morphological and anatomical differentiation, yet their systematic position remains one of apparent isolation, and it has recently been claimed that they have been derived independently of all the other ...

Historical biogeography of the widespread macroalga Sargassum (Fucales, Phaeophyceae) [PDF]
Sargassum is a cosmopolitan brown algal genus spanning the three ocean basins of the Atlantic, Pacific and Indian Oceans, inhabiting temperate, subtropical and tropical habitats. Sargassum has been postulated to have originated in the Oligocene epoch approximately 30 mya according to a broad phylogenetic analysis of brown macroalgae, but its ...

Feulgen Reaction in the Fucales [PDF]
THE Feulgen reaction has not been used to any great extent in cytological investigations of the larger brown algae1–4, possibly on account of the difficulty of obtaining consistent results. The following technique has now been applied successfully to growing vegetative apices and to developing receptacles of all the British members of the Fucales, with

Loss of canopy-forming algal richness and coverage in the northern Adriatic Sea
Canopy-forming macroalgae, especially those belonging to the order Fucales, are creating the so-called brown algal forests that are considered amongst the most productive assemblages in the shallow coastal area.

Macroalgal assemblages as indicators of the ecological status of marine coastal systems: A review
Macroalgae have been utilized as biological indicators of ecosystem health in many monitoring programs worldwide. These programs have utilized various methods to quantify macroalgal community structures.

Dynamic structural colour increases photosynthetic performance in the alga Ericaria selaginoides
Structural colour occurs when nanoscale structures interfere with incident light transmission and reflect particular wavelengths. The brown alga Ericaria selaginoides (Fucales, Phaeophyceae) has an opalescent photonic crystal anatomy that creates the ...

Hormophysa cuneiformis (Phaeophyta: Fucales) in Micronesia [PDF]
Specimens of Hormophysa cuneiformis ( J. Gmelin) P. Silva, collected by R. E. DeWreede in July 1968 and by the author in January 1971 from Palau, are documented for the first time and represent the first collections of a member of the family Cystoseiraceae from Micronesia. A single specimen 6 cm tall of H. cuneiformis was collected 4.5 yr later in July
