The Newman method, modified for the estimation of the total thallus length of filamentous algae
Provedor de dados: 27
Autores: Gillis, J.
Newman's (1966) method of total root length estimation is modified and adapted to measure total length of filamentous algae in culture (i.c. &lt;i&gt;Polysiphonia&lt;/i&gt;). This method makes possible a measurement and an estimation of the growth of the algae in culture without disturbing them. The petri dishes are placed on a 1x1 mm grid and the filament/grid intersections are counted. Total filament length (T) is given by T = Pi N (LxW)/4(LxW), with N = the number of intersections, L = the length and W = width of area in which the thallus is situated. Total filament length of &lt;i&gt;Polysiphonia&lt;/i&gt; in culture estimated by the Newman method is compared with camera lucida measurements. The correlation between the results obtained by the 2...

The authors describe 12 seaweeds that have not been collected previously from the French coasts of the Channel: The Chlorophyceae &lt;i&gt;Rosenvingiella polyrhiza, Ulothrix palusalsa, U. speciosa, Ulva pseudocurvata, U. scandinavica, Urospora bangioides&lt;/i&gt;, the Phaeophyceae &lt;i&gt;Isthmoplea spaerophora, Pogotrichum filiforme&lt;/i&gt; and &lt;i&gt; Stictyophon&lt;/i&gt; cf.&lt;i&gt;soriferus&lt;/i&gt; and the Rhodophyceae &lt;i&gt;Aglothamnion roseum, Ceramium shuttleworthianum&lt;/i&gt; and &lt;i&gt;Rhodomela confervoides&lt;/i&gt;. Ecological data are added to the morphological and anatomical description.

Quelques Chlorophyceae et Phaeophyceae marines nouvelles pour la flore belge, provenant du Bassin de Chasse d'Oostende
Provedor de dados: 27
Autores: Coppejans, E.; Gillis, J.
Description of 5 seaweeds, new for the Belgian flora, collected in May 1982 in the Sluice Dock of Ostend. There are 3 Chlorophyceae: &lt;i&gt;Enteromorpha kylinii, E. ralfsii, Ulva scandinavica&lt;/i&gt;, and 2 Phaeophyceae: &lt;i&gt;Ectocarpus confervoides&lt;/i&gt; var. &lt;i&gt;confervoides, Punctaria latifolia&lt;/i&gt;. The last, rather infrequent species is studied in detail.
