The utility of species distribution models for applications in invasion and global change biology is critically dependent on their transferability between regions or points in time, respectively. We introduce two methods that aim to improve the transferability of presence-only models: density-based occurrence thinning and performance-based predictor selection. We evaluate the effect of these me...

Seventy five patients with oral lesions attending the different departments of Rajah Muthiah Medical College and Hospital, Annamalai University were screened for Candida. Forty six (61.3%) Candida strains were isolated from the oral lesions. Of the 46 Candida strains, Candida albicans accounted for 35 (76.08%), Candida glabrata for 5 (10.86%), Candida tropicalis and Candida krusei for 2 (4.34%)...

In the early 1980s, a biologist at the tropical aquarium in Stuttgart, Germany, noticed that the beautiful green alga Caulerpa taxifolia (Fig. 1) would make an ideal aquarium decoration. It does not wither, it is fast growing and it withstands cool temperatures. In the following years, many aquariums acquired Caulerpa plants from Stuttgart, among them the Oceanographic Museum of Monaco, from wh...

Molecular phylogenetic relationships within the Chlorophyta have relied heavily on rRNA data. These data have revolutionized our insight in green algal evolution, yet some class relationships have never been well resolved. A commonly used class within the Chlorophyta is the Ulvophyceae, although there is not much support for its monophyly. The relationships among the Ulvophyceae, Trebouxiophyce...

Fronds had higher mean caulerpenyne concentration than stolons in Caulerpa prolifera, C. taxifolia and C. racemosa. C. prolifera had higher mean caulerpenyne content w7.29"0.64% caulerpenyne/frond dry weight (DW)x than C. taxifolia (5.47"0.32% caulerpenyne/frond DW) and C. racemosa (0.43"0.07% caulerpenyne/frond DW). C. prolifera had reduced content from May to October in fronds, with no clear ...

Caulerpa racemosa is a tropical green alga introduced into the Mediterranean probably as an immigrant from the Red Sea. This study evaluated the modifications caused by C. racemosa invasion on the structure of the benthic macroalgal community near Leghorn (northwestern Mediterranean). To achieve this objective, we studied invasion by C. racemosa of algal assemblages on 2 different substrata by ...

Two distinct patterns of cytoplasmic streaming in the leaf of Caulerpa prolifera are described. Broad, longitudinally running, two-way streams are restricted to the endoplasm of one leaf surface. Also present are large numbers of narrow, two-way streams that coil helically throughout the endoplasm surrounding the central vacuole. Numerous unique bundles of aggregated, evenly spaced, oriented mi...
