Sexually-mature tortoises are at greatest risk of disease

Currently, upper respiratory tract disease (URTD) and habitat loss are contributors to a decline in gopher and desert tortoise populations. And since these reptiles are keystone species—that is, the habitats they create are home to more than 300 other species—their population decline significantly affects the ecosystem. According to a recent study in Ecology, sexually-mature male tortoises were at the greatest risk of carrying and spreading URTD due in large part to their social behavior.

To fly or not to fly?

Evolution can do funny things. Like producing the amazing feat of flight in a lineage of reptiles, which over time led to an adaptive radiation seldom rivaled in the history of animals. And then producing, in some 30 species of birds, the loss of the adaptation altogether. It would seem a ridiculous thing to do, to give up the power…
