An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough to detect prey, and strong if it is powerful enough to stun or kill. The field may be in brief pulses, as in the elephantfishes, or a continuous wave, as in the knifefishes.
As magnetic and electrical fields are related, magnetoreception via electromagnetic induction in the ampullae of Lorenzini is possible. A study from 2004 shows this magnetoreception by cartilaginous fish as they respond to artificially generated magnetic fields in association with food rewards.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
Another possible mechanism of magnetoreception in animals is electromagnetic induction in cartilaginous fish, namely sharks, stingrays, and chimaeras. These fish have electroreceptive organs, the ampullae of Lorenzini, which can detect small variations in electric potential. The organs are mucus-filled and consist of canals that connect pores ...
Magnetobiology is the study of biological effects of mainly weak static and low-frequency magnetic fields, which do not cause heating of tissues. Magnetobiological effects have unique features that obviously distinguish them from thermal effects; often they are observed for alternating magnetic fields just in separate frequency and amplitude intervals.
The effects of electrotropism on plant growth can be witnessed in the grape “Uslu”. An electric field has similar forces as a magnetic field. A magnetic field can be created by using an alternating electric field. Thus, a magnetic field may have similar effects on plants as an electric field used in electrotropism.
Electromagnetic field receptors (ampullae of Lorenzini) and motion detecting canals in the head of a shark Active electrolocation. Conductive objects concentrate the field and resistive objects spread the field. Electroreception is the ability to detect electric fields or currents.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
