Trace metal enhancement in the biotic and abiotic components of an estuarine tidal front

Journal of Geophysical Research: Oceans, 1978
A frontal system of lower Delaware Bay was investigated to illustrate the role that such tidal fronts can have in concentrating trace metals and serving as a means for introducing trace metals into the trophic hierarchy of estuaries. This frontal system typically develops on ebb tide and can extend at least 32 km parallel to the central axis of ...

A novel and effective technique to reduce electromagnetic radiation absorption on biotic components at 2.45 GHz

Electromagnetic Biology and Medicine, 2022
A strong evidence of the effects of radiation absorption on the living community together with a better solution to reduce the radiation intensity without compromising the usage of wireless communication systems is presented. This study analyses the radiation effects on living things and validates the proposed techniques for specific absorption rate ...

Biotic homogenization of urban floras by alien species: The role of species turnover and richness differences

, 2016
We ask whether changes in beta diversity of plant communities due to introduction of alien species result from changes in species turnover or from differences in species richness.

The use of biotic and abiotic components of Red Sea coastal areas as indicators of ecosystem health

Ecotoxicology, 2015
A biomonitoring study was conducted using some biotic (Pomadasys hasta and Lutjanus russellii fish) and abiotic (water and sediment) components of the Red Sea coast of Hodeida, Yemen Republic along two polluted sites (Al-Dawar beach and Urj village) in comparison to a reference site (Al-Nukhailah beach).

Heavy Metal Contamination in Biotic Component: A gradual case study in West Bengal

International Journal of Chemical and Environmental Sciences, 2020
Fish is a popular human food. Over two-and-a-half billion people globally obtain their daily nutrient intake from fish. In India, it is a major dietary component for over 50 percent, and is a particularly important nutrition source for the poor. Mercury is a deadly environmental pollutant, both in its elemental form and in combination with other ...

Biotic and Abiotic Components of Marine Ecosystem

2023
An aquatic ecosystem is a water-based environment. Aquatic ecosystems include the marine ecosystem and freshwater ecosystems. Two-thirds of the total surface area of the planet is covered by marine water. These ecosystems can be classified into two main categories; i) water/pelagic environment (including; neritic and oceanic zones) and; ii) bottom ...

Soil Temperature Interactions with the Biotic Components of Vascular Wilt Diseases

1989
Temperature is an environmental factor which strongly affects wilt diseases since it has an influence on each of the three biotic components involved in the production of the syndrome of wilt diseases, i.e., the pathogen, the host plant and soil microorganisms. Surface temperatures vary with latitude and altitude and change cyclically each day and each
