Much of the evidence for earthworm effects on soil processes comes from agroecosystems and involves a small group of European lumbricids (family Lumbricidae in the order Oligochaeta). In North America, south of the southern limit of the Wisconsinan glaciation, several native genera exist. However,...
terrestris) and endogeic earthworm species (Aporrectodea caliginosa, A. rosea and Octolasion cyaneum) and confirmed the preference for dark pigmented fungi. However, the authors also documented that earthworms preferentially feed on plant pathogens (Fusarium nivale and Rhizoctonia solani). Strong ...

contingent resort (Fig.S7). Notably, test confirm that the inclusion of these magnetic particles neither pulls the mag-bots towards the induction coils’ alternating magnetic fields (MovieS2), nor prohibits the mag-bots from moving away from them (MovieS3), which together ensure that it is the...
solo, a number of whom completed over 100 miles. The first few laps were quite pleasant, completed at a good pace in the afternoon sun; by the end I had revised my understanding of the term ‘pain threshold’ several times, and a moderately nimble earthworm would have run rings around ...
tetraptera against adult earthworm Pheretima posthuma. They showed that the fruit aqueous extract was the effective against P. posthuma causing worm paralysis and death. Their study also revealed that the fruit aqueous extracts worked synergistically with albendazole and potentiated its antihelminthic ...
The shoot subsequently turns brown and dies. The fruit is most vulnerable to infection when young, but all parts of the fruit cluster remain susceptible until maturity. As with leaf infection, the severe development of the disease can result in premature abscission. During the summer, the fungus...
improved drainage and water holding capacity and increased levels of microbial and earthworm activity as well as a reduction in greenhouse gas emissions. Reduced tillage techniques can also improve the timeliness of crop establishment and retain moisture which will aid crop establishment and ultimately im...
In contrast with animals with rigid skeletons, animals such as earthworms and caterpillars have less restrictions in movement and adaption of their shapes. They can deform their soft and compliant bodies to become more flexible. Many earthworm-like robots use SMA actuators, pioneered in the earthworm...
The two helices are connected by a loop consisting of two inverse gamma-turns and a beta-turn. This sequence, residues 11–49, thus constitutes a rather unique helical hairpin structure [2]. Considerable data is available implicating some amino acid side chains in the toxic action of toxin B...
