Single infection with Batrachochytrium dendrobatidis or Ranavirus does not increase probability of co-infection in a montane community of amphibians

We found that the co-occurrence of both pathogens in a particular host is not common except in highly susceptible life-stages, and that single infections are the most common situation. Moreover, we found that the occurrence of one pathogen in a particular host did not predict the occurrence of the other. We attribute these results to the niches in which both pathogens proliferate in amphibian hosts. Leer más.

Flashy lizards are more attractive to mates and to predators

In the lizard world, flashy colors attract the interest of females looking for mates. But they can make colorful males desirable to other eyes, too — as lunch. L. Swierk, J. F. F. Boyer, J. Chang, M.
