Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the herpestid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted.
An improper nitrogen cycle, inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental fish in a tank. Despite this, many diseases in captive fish can be avoided or prevented through proper water conditions and a well-adjusted ecosystem within the tank.
Lacebugs of the genus Corythucha are subject to egg predation by obligate egg predators like mirid bugs, pirate bugs, and thrips, and respond to it in varying ways. C. solani mothers defend their eggs from predators, while C. marmorata buries its eggs inside leaves and distributes them in space and time. [2]
Top row: unaffected fish; bottom row: fish preyed upon by the carnivorous alga Pfiesteria shumwayae. Predatory dinoflagellates are predatory heterotrophic or mixotrophic alveolates that derive some or most of their nutrients from digesting other organisms. About one half of dinoflagellates lack photosynthetic pigments and specialize in ...
Adult fish also prey on fish eggs and larvae. For example, haddock were observed satiating themselves with herring eggs back in 1922. [14] Another study found cod in a herring spawning area with 20,000 herring eggs in their stomachs, and concluded that they could prey on half of the total egg production. [17] Fish also cannibalise their own eggs.
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...
