because they are sensitive to pollution and that how you can tell how polluted a river is
Yes, mayfly nymphs can serve as indicators of water quality. They are sensitive to pollution and changes in their environment, so their presence typically signifies good water quality, while their absence or a decline in their population may indicate poor water conditions. Monitoring mayfly populations can thus be useful for assessing ecosystem health.
why cannot a mayfly eat
Mayflies are sensitive to changes in water quality, so their presence or absence can indicate the health of a water body. High levels of pollution can harm mayfly populations, leading to declines in their numbers. By studying mayflies in a water system, scientists can assess pollution levels and overall ecosystem health.
Some species that can indicate pollution in fresh water include certain types of algae (e.g. green algae blooms), macroinvertebrates like mayflies and stoneflies that are sensitive to pollution, and certain fish species like carp that can thrive in degraded water conditions. Monitoring the presence and abundance of these species can help determine the level of pollution in a freshwater ecosystem.
yes a fish can eat a mayfly Nymph.
A Mayfly Nymph breathes with gills on the side of their body.
Spiny crawler is what the Hendrickson mayfly (Ephemerella subvaria) nymph is called.Specifically, the nymph is the immature developmental stage of the mayfly. It is what hatches out of the eggs laid by the female after mating with the male Hendrickson mayfly. It looks like a developing, smaller version of the mature Hendrickson mayfly.
Bees and other insects can see pollution, unlike us humans.
