ALLELOPATHIC INFLUENCE OF AQUATIC WEEDS ON AGRO-ECOSYSTEMS: A REVIEW Planta Daninha
ABBAS,T.; NADEEM,M.A.; TANVEER,A.; SYED,S.; ZOHAIB,A.; FAROOQ,N.; SHEHZAD,M.A..
ABSTRACT Aquatic weeds are higher plants found in the aquatic ecosystem and in anaerobic rice fields, where they have no economic benefits. The continuance of aquatic weeds is more widespread than terrestrial weeds because in aquatic ecosystems there is very little fluctuation in the environmental conditions compared with terrestrial ecosystems. Scientists have been working to address the harmful allelopathic effects of aquatic weeds on the aquatic ecosystem, but limited information is available on the allelopathic influence of aquatic weeds on agro-ecosystems through the release of phytotoxic compounds. Phytotoxic chemicals released by different aquatic weeds into irrigation water and/or directly into rice ecosystems might have a significant inhibitory...

Reference points for predators will progress ecosystem‐based management of fisheries ArchiMer
Hill, Simeon L.; Hinke, Jefferson; Bertrand, Sophie; Fritz, Lowell; Furness, Robert W.; Ianelli, James N.; Murphy, Matthew; Oliveros‐ramos, Ricardo; Pichegru, Lorien; Sharp, Rowland; Stillman, Richard A.; Wright, Peter J.; Ratcliffe, Norman.
Ecosystem‐based management of fisheries aims to allow sustainable use of fished stocks while keeping impacts upon ecosystems within safe ecological limits. Both the FAO Code of Conduct for Responsible Fisheries and the Aichi Biodiversity Targets promote these aims. We evaluate implementation of ecosystem‐based management in six case‐study fisheries in which potential indirect impacts upon bird or mammal predators of fished stocks are well publicized and well studied. In particular, we consider the components needed to enable management strategies to respond to information from predator monitoring. Although such information is available in all case‐studies, only one has a reference point defining safe ecological limits for predators and none has a method to...
