The classification of organisms allows us to group them based on their characteristics Over the years, this has led to a better understanding of the species around us All vertebrates belong to a class of animals called chordates Chordates, at some point in their lives, have a notochord, a flexible rod supporting the chordate’s back They

- Amphibian fungal panzootic causes catastrophic and ongoing . . .
We examined host life history traits and environmental conditions to understand why some species declined more severely than others, using multinomial logistic regression and accounting for the degree of evidence that chytridiomycosis was implicated in each species’s decline (fig S2 and table S2)
