A fungus of the genus Arthrobotrys, showing adhesive nets which it uses to trap nematodes. Numbered ticks are 122 μm apart.
Fungi that grow on the epidermis, hair, skin, nails, scales or feathers of living or dead animals are considered to be dermatophytes rather than carnivores. Similarly, fungi in orifices and the digestive tract of animals are not carnivorous, and neither are internal pathogens. Neither are insect pathogens that stun and colonize insects normally labelled carnivorous if the fungal thallus is mainly in the insect as does Cordyceps, or if it clings to the insect like the Laboulbeniales. All of these are examples of parasitism or scavenging.
Two basic trapping mechanisms have been observed in carnivorous fungi that are predatory on nematodes:
carnivorous, fungus, carnivorous, fungi, predaceous, fungi, fungi, that, derive, some, most, their, nutrients, from, trapping, eating, microscopic, other, minute, animals, more, than, species, have, been, described, belonging, phyla, ascomycota, mucoromycotina. Carnivorous fungi or predaceous fungi are fungi that derive some or most of their nutrients from trapping and eating microscopic or other minute animals 1 More than 200 species have been described belonging to the phyla Ascomycota Mucoromycotina and Basidiomycota They usually live in soil and many species trap or stun nematodes nematophagous fungus while others attack amoebae or collembola A fungus of the genus Arthrobotrys showing adhesive nets which it uses to trap nematodes Numbered ticks are 122 mm apart Fungi that grow on the epidermis hair skin nails scales or feathers of living or dead animals are considered to be dermatophytes rather than carnivores Similarly fungi in orifices and the digestive tract of animals are not carnivorous and neither are internal pathogens Neither are insect pathogens that stun and colonize insects normally labelled carnivorous if the fungal thallus is mainly in the insect as does Cordyceps or if it clings to the insect like the Laboulbeniales All of these are examples of parasitism or scavenging Two basic trapping mechanisms have been observed in carnivorous fungi that are predatory on nematodes constricting rings active traps adhesive structures passive traps Sequencing of ribosomal DNA has shown that these trap types occur in separate fungus lineages 2 an example of convergent evolution See also edit nbsp Fungi portalCarnivorous plant Predatory dinoflagellate Protocarnivorous plantReferences edit Pramer D 1964 Nematode trapping fungi Science 144 382 388 Ahren D M U Bjorn amp A Tunlind 1998 Phylogeny of nematode trapping fungi based on 18S rDNA sequences FEMS Microbiology Letters 158 179 184 Hauser J T 1985 Nematode Trapping Fungi PDF 815 KiB Carnivorous Plant Newsletter 14 1 8 11 reprinted from Carolina Tips Carolina Biological Supply Company External links editNematode Destroying Fungi Retrieved from https en wikipedia org w index php title Carnivorous fungus amp oldid 1191540810, wikipedia, wiki, book, books, library,
