Parasites a key to the decline of red colobus monkeys in forest fragments
...m into contact with more parasites. Their compromised nutritional status also weakens them, giving parasites the edge, Gillespie said.
We asked how parasitism
plays into this dynamic of some species doing well and others not doing well after forest fragmentation, Gillespie said. This is giving us a new windo...
Reasons why men die earlier
...se species where males die younger than females, the males suffer a disproportionately high rate of parasitism. The authors also show that male-biased parasitism
is the general rule among mammals, and that it is most extreme in those species where male-male competition for mates is most severe. Taken together, ...
Worm genome offers clues to evolution of parasitism
The genome of a humble worm that dines on the microbial organisms covering the carcasses of dead beetles may provide clues to the evolution of parasitic worms, including those that infect humans, say scientists at Washington University School of Medicine in St. Louis and the Max-Planck Institute f...
Insight into the evolution of parasitism
This release is also available in German .
Scientists at the Max Planck Institute for Developmental Biology, together with American colleagues, have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. In their work, which ha...

"In the absence of parasites, the toads and frogs are pure competitors," Johnson said. "But when trematode parasitism
is present in the ecosystem, the adage 'the enemy of my enemy is my friend' comes into play for the toads, which are essentially shielded from infecti...

Mice mothers devote energies to offspring when life is threatened

has the greatest impact on current reproductive ability."
In other words, "infection in animals typically leads to responses that invest in the su...
UCR-led research team uses tiny wasp to wipe out major agricultural pest in Tahiti
...luations, Hoddle and his colleagues released nearly 14,000 parasitic wasps at 27 sites in Tahiti between May 2005 and October 2005, resulting in rapid parasitism
