Harmful algal blooms (HABs) are a serious environmental problem globally. The ability of cyanobacteria, one of the major causative agents of HABs, to grow in heavy metal polluted areas is proving a challenge to environmental restoration initiatives. Some cyanobacteria secrete toxins, such as microcystin, that are potentially dangerous to animals and humans.(More)
BACKGROUND It has been reported that some marine cyanophage are temperate and can be induced from a lysogenic phase to a lytic phase by different agents such as heavy metals. However, to date no significant reports have focused on the temperate nature of freshwater cyanophage/cyanobacteria. Previous experiments with cyanophage AS-1 and cyanobacteria(More)
Tourism development in protected areas inevitably induces a decline in the ecological environment and species survival. However, the degree of impact depends on target species’ environmental quality tolerance and the number of tourists. Each fish can tolerate a specific level of water quality. Water quality should not deteriorate below this level as a(More)
