Collectively, the examples described here illustrate how parasites may have opposing net effects on biodiversity, which depend on the context of the parasite-host relationship (e.g., whether host ...

And, of course, I wrote a whole book about them, but there are still so many examples that just didn’t even make it into the book. So, these parasites are a very, very rich source of study, and ...

These parasites can lead to human disease by acting as vectors of infectious pathogens. For example, Lyme disease is a bacterial infection passed to humans through a bite from an infected tick.

This behavior, called brood parasitism, is observed in fishes, frogs, and birds, with the most famous example being that of the cuckoo. Such brood parasitism has now also been observed in the insect ...

Examples of parasitism in the fossil record are also diverse, "from fleas on mammals to mites on insects, and even potentially single-celled parasites on Tyrannosaurus rex," said study co-author ...

Though a small handful of mind-controlling parasites get most of the attention, in a recent TED talk science journalist Ed Yong explores how parasites are pulling the strings all around us:. Some ...

Parasites can also help their hosts in other ways, for example by causing more serious disease in other species. This is one of the main reasons why grey squirrels have rapidly displaced red ...

Using genetic data from the genomes of anglerfishes, the researchers showed how complex features — such as sexual parasitism — assisted some anglerfish groups in transitioning from roaming shallow ...

Brood parasitism (attacking the immature stages, rather than the adult ants), for example, is an extremely rarely observed and little-studied phenomenon. However, ...

Molecular biologists have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. They have shown that the genome of the nematode ...
