Cyclea peltata is locally called as “kariballi” belongs to the family Menispermaceae. It is a twining shrub, traditionally used in the treatment of wounds, skin infections and muscular sprains by local folk medicinal practioners. The present study was designed to determine the phytochemical compounds in the methanolic extract of Cyclea peltata by GC-MS analysis. GC-MS chromatogram of the methan...

Alien Invasion: the spread of Caulerpa taxifolia in Australian waters The eradication or control of introduced marine pests will represent one of the greatest challenges of this century. Indeed, hundreds of introduced marine species are already present in Australian waters. Marine pests pose such a challenge because by the time they are discovered they are usually well established and almost im...

Biological invasions threaten biodiversity worldwide. Nonetheless, a unified theory linking disturbance and resistance to invasion through a mechanistic understanding of the changes caused to biodiversity is elusive. Building on different forms of the disturbance-biodiversity relationship and on the Biotic Resistance Hypothesis (BRH), we constructed conceptual models showing that, according to ...

The genus Caulerpa is known for its invasion of tropical, subtropical, and temperate coastal waters. Whereas the role of humans as vectors for the introduction of Caulerpa has been well documented, other anthropogenic factors that may mediate the success of an invasion are poorly understood. We provide evidence that a recent invasion of Caulerpa ollivieri into shallow Bahamian seagrass meadows ...

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 present study, we tested in vitro different parts of 35 plants used by tribals of the Similipal Biosphere Reserve (SBR, Mayurbhanj district, India) for the management of infections. From each plant, three extracts were prepared with different solvents (water, ethanol, and acetone) and tested for antimicrobial (E. coli, S. aureus, C. albicans); anthelmintic (C. elegans); and antiviral (en...

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 ...
