Mature horses appear to develop a certain degree of resistance to this parasite, but it is a concern for younger horses up to about two years old. [4] P. equorum is one of the few parasites where a natural immunity develops in the host. [3] However, when an infection is found in an adult horse, both the worm and egg counts are substantially low ...
Earthworms are environmental indicators of soil health. Earthworms feed on the decaying matter in the soil and analyzing the contents of their digestive tracts gives insight into the overall condition of the soil. The earthworm gut accumulates chemicals, including heavy metals such as cadmium, mercury, zinc, and copper. The population size of ...
This form of activity is often considered a way to escape floods and waterlogged burrows. However, this cannot be the case since L. terrestris, like other earthworms, can live in oxygenated water for long periods of time, stretching to weeks. Under less severe environmental conditions where air temperature and moisture are sufficient, the worm ...
Gippsland earthworm colonies are small and isolated, [9] and the species' low reproductive rates and slow maturation make those small populations vulnerable. [9] Their natural habitats are grasslands, and while they can survive beneath pastures, [9] cultivation, heavy cattle grazing and effluent run-off are adversarial to the species. [9]
Some species of hammerhead worms produce a type of neurotoxin called tetrofotoxin to hunt creatures such as earthworms. They will paralyze a worm with the neurotoxin (found in the mucus secreted ...
In ecosystems, earthworms such as Lumbricus rubellus increase the rate of transfer between trophic levels by making it easier for plants to uptake nutrients. In food chains, earthworms such as Lumbricus rubellus are primary consumers whose role is converting the energy synthesized by photosynthetic plants into food for animals at higher trophic ...
