Microfauna (from Ancient Greek mikros 'small' and from Latin fauna 'animal') are microscopic animals and organisms that exhibit animal-like qualities and have body sizes that are usually <0.1mm. [ 1 ] [ 2 ] Microfauna are represented in the animal kingdom (e.g. nematodes , small arthropods ) and the protist kingdom (i.e. protozoans ).
About 90% of nematodes reside in the top 15 cm (6") of soil. Nematodes do not decompose organic matter, but, instead, are parasitic and free-living organisms that feed on living material. Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute.
"Nematodes often eat tardigrades, and so it felt like the stakes were quite high," Quinten Geldhof, the 24-year-old hobbyist who took the video of this "wild ride" through a microscope, told ...
Living among the mats are bacteria, yeasts, molds, and an array of microscopic invertebrates that feed on microbes, algae, and detritus: nematodes, protozoa, rotifers, tardigrades, and occasionally, mites and springtails. [4] Even simpler communities exist in the arid soils that occupy the majority of the landscape. [3]
Tardigrades have been shown to respond to different temperature changes at different developmental stages. Specifically, the younger the egg, the less likely it is to survive extreme environments. However, not too long after development, tardigrades demonstrate a remarkable ability to withstand these conditions.
Eutely has been confirmed to certain degrees in various forms of diversity and sections of the tree of life.Examples include rotifers, many species of nematodes (including ascaris and the organism Caenorhabditis elegans whose male individuals have 1,033 cells [3] [4]), tardigrades, larvaceans and dicyemida.
Tardigrades (/ ˈ t ɑːr d ɪ ɡ r eɪ d z / ⓘ), [1] known colloquially as water bears or moss piglets, [2] are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them Kleiner Wasserbär ' little water bear ' .
The habit of feeding on nematodes has arisen many times among fungi, as is demonstrated by the fact that nematophagous species are found in all major fungal groups. [3] Nematophagous fungi can be useful in controlling those nematodes that eat crops. Purpureocillium, for example, can be used as a bio-nematicide.
