A total of 1951 species of freshwater and marine fishes belonging to 704 genera and 186 families are recorded in Malaysia. Almost half (48%) are currently threatened to some degree, while nearly one third (27%) mostly from the marine and coral habitats require urgent scientific studies to evaluate their status. Freshwater habitats encompass the highest percentage of threatened fish species (87%...
BACKGROUND & OBJECTIVES Indigenous larvivorous fishes bear potential for regulating vector mosquitoes through trophic interactions. The mosquito prey preference of five indigenous larvivorous fishes in the presence of alternative food items was assessed to highlight their use in mosquito vector management. METHODS Laboratory experiments were carried out using the larvivorous fishes Ambassis (...
Based on life history and ecological characteristics, several authors have placed seamount fishes at the extreme end of the vulnerability spectrum. However, it was still unclear if there is justification for the generalization that seamount fishes overall possess specific life-history characteristics that render them more vulnerable to fishing than other species. In this contribution, we test t...
Mycotoxins are secondary metabolic products of fungi. They poisonous, carcinogenic, and mutagenic in nature pose a serious health threat to both humans animals, causing severe illnesses even death. Rapid, simple low-cost methods detection mycotoxins immense importance great demand the food beverage industry, as well agriculture environmental monitoring, and, for this purpose, lateral flow immun...

برگچه های 111 نمونه هرباریومی از گون های کرک دوشاخه ایران، شامل82 گونه از 13 بخش، به منظور تشخیص ترکیبات ازت دار آلیفاتیک سمی مورد بررسی قرار گرفتند. کاتابولیت های ترکیبات ازت دار، 3-نیترو 1-پروپانول و اسید3- نیتروپروپیونیک، برای احشام سمی هستند. بعلاوه این ترکیبات در طبقه بندی گیاهان نیز حائز اهمیت می باشند. وجود این نیتروتوکسین ها در 4 گونه از 82 گونه مذکور گزارش می شود.
It has recently been shown by one of us (W. W. Ford’) that the poisons of the fungus Amanita phalloides, the variety responsible for the great majority of deaths from mushroom intoxication, belong to the group of bacterial toxins. They were thus classified in virtue of their causing characteristic lesions in animals after a definite latent period, and because an immunity may be established towa...
