Detailed information about the location and extent of zooplankton patches is fundamental to understand how abiotic and biotic forces interact to structure the spatial distribution of zooplankton. We mapped zooplankton patchiness in a Minnesota lake during spring, summer, and autumn with high-frequency (192-kHz) single-beam sonar. Conventional plankton samples of aggregations detected acoustical...

Rapid industrialization has resulted in the release and subsequent accumulation of heavy metals (HMs) various environmental matrices, which poses serious health threats globally. Utilizing native plant species to extract such HMs from soil may be an efficient cost-effective remediation approach. Thus, HM industrial area Al-Qassim province, Saudi Arabia, was investigated this study, phytoremedia...

Background: Cystic echinococcosis (CE), caused by the larval stage of Echinococcus granulosus, is a zoonotic disease and has global distribution. Today, herbal compounds are highly regarded in order to inactivate hydatid cyst protoscoleces. This study aimed compare scolicidal activity hydroalcoholic extract Pulicaria gnaphalodes Alhagi maurorum against protoscoleces vitro. Methods: The P. A. ex...

Dormancy is a common mechanism employed by short-lived organisms for persistence in a variable environment. Theory suggests that the fraction of propagules that terminate dormancy each year should be ,100% when recruitment success varies temporally. Moreover, the fraction of propagules that resumes development should vary across habitats that differ in the probability of successful recruitment ...
