We provide descriptions, with illustrations of internal structures, for 18 new species of Pheretima from Mt. Malindang, Misamis Occidental Province, Mindanao Island, Philippines. Among the 18 species, 11 belong to the P. sangirensis species group, characterized by having a pair of spermathecal pores in the intersegmental furrow of 7/8 and lacking penial sheaths in the copulatory bursae: P. macu...

The anthelmintic activity of the Imethanolic extract of the root bark of Carissa carandas was evaluated on adult Indian earthworm (Pheretima posthuma) using albendazole as a reference standard. The extract caused paralysis followed by the death of worm at the tested dose level. The extract at the highest tested concentration has anthelmintic activity comparable with that of standard drug albend...

Coralline algae form abundant and ecologically important submerged aquatic vegetation habitats throughout the world. However, algal performance is threatened by climate change ocean acidification. Previous studies suggest that their photosynthetic will be compromised mainly at elevated temperatures. Understanding impact of diverse scenarios requires a clear thorough comprehension response to te...

Antianthelmintic activity of successive extracts (chloroform, acetone, ethanol and aqueous) of Nauclea orientalis leaves were evaluated separately on adult Indian earthworm (Pheretima posthuma) and compared with that of albendazole. It was found that the extracts exhibited, respectively dose-dependent action and inhibition of spontaneous motility (paralysis) and death of earthworms. The results...

Accepted on 9 December 2014 _____________________________________________________________________________ ABSTRACT The synthesis and characterization of new series of thiadiazepine derivatives of sultams have been presented. The structures were confirmed by elemental analysis, IR spectral,H NMR spectral data. All the compounds were screened for in vitro antimicrobial and anthelmintic activities...
