Calculating the ecological impacts of animal-borne instruments on aquatic organisms

Global ecological impacts of invasive species in aquatic ecosystems.

The introduction of invasive species, which often differ functionally from the components of the recipient community, generates ecological impacts that propagate along the food web. This review aims to determine how consistent the impacts of aquatic invasions are across taxa and habitats. To that end, we present a global meta-analysis from 151 publications (733 cases), covering a wide range of ...

Evaluation of the ecological impacts of beaver reintroduction on aquatic systems

Effects of triclosan on various aquatic organisms.

Triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) is widely used as an antibacterial agent in various industrial products, such as textile goods, soap, shampoo, liquid toothpaste and cosmetics, and often detected in wastewater effluent. However, there is a paucity of data on the toxicity of triclosan and its effects on aquatic organisms. In this study, the acute toxicity of triclosan to the...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

Metabolomics of aquatic organisms: the new ‘omics’ on the block

Environmental metabolomics can be defined as the application of metabolomics to characterise the metabolism of free-living organisms obtained from the natural environment and of organisms reared under laboratory conditions, where those conditions serve to mimic scenarios encountered in the natural environment. This approach has considerable potential for characterising the responses of organism...
