Abstract Toxoplasma gondii is a zoonotic parasite with a wide host range that includes humans, domestic animals and wild animals.Small mammals serve as intermediate hosts for T.gondii and may contribute to the persistence of this parasite in the environment.Mass mortality in wild animals and deaths in rare endemic species make the study of this par
Learned vocal variation is associated with abrupt cryptic genetic change in a parrot species complex.
Contact zones between subspecies or closely related species offer Floor Mats valuable insights into speciation processes.A typical feature of such zones is the presence of clinal variation in multiple traits.The nature of these traits and the concordance among clines are expected to influence whether and how quickly speciation will proceed.Learned
