Brevinin-1 and multiple insulin-releasing peptides in the skin of the frog Rana palustris
"... Few studies have comprehensively examined amphibian granular gland secretions for novel insulinotropic peptides. This study involved isolation and characterisation of bio-logically active peptides from the skin secretions of Rana palustris frogs. Crude secretions obtained by mild electrical stimulat ..."

"... In order to maintain pond-breeding amphibian species richness, it is important to understand how both natural and anthropogenic disturbances affect species assemblages and individual species distributions both at the scale of individual ponds and at a larger landscape scale. The goal of this project ..."

of this project was to investigate what characteristics of ponds and the surrounding wetland landscape were most effective in predicting pond-breeding species richness and the individual occurrence of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana) and pickerel frog (Rana palustris) breeding sites in a
Southern Leopard Frog
"... This attractive frog is named for its spots, which are reminiscent of the big cat. The taxonomic status of leopard frogs has been widely debated. At one time, all were regarded as a single species, Rana pipiens. Today this group is recognized as a large complex made up of distinct species, at least ..."

"... pine barrens may be a limiting factor in the distribution of anurans. Rana virgatipes and Hyla andersoni embryos tolerate more strongly acid solutions than any of the other species tested. Rana palustris and Acris g. crepitans have the least tolerance to such conditions and these species are practic ..."
