Dendropsophus branneri is a small hylid tree frog endemic to the Atlantic Forest region of Brazil.[3] It feeds mainly on arthropods[4] and is preyed upon by various invertebrates (e.g., giant aquatic bugs, spiders) and vertebrates (e.g., snakes, birds).[5] Although currently classified by the IUCN Redlist as "least concern",[1]D. branneri suffers rapid habitat loss due to residential development, agriculture, logging, and clearing for pastureland.[3][6] Male D. branneri are noted for their fighting call, which differs significantly in frequency, duration, and pulses per call compared to their mate advertisement call.[7] Males are also noted for their willingness to escalate physical altercations against other males, which includes kicking, pushing, and wrestling their opponent into non-dominant positions.[7] Unlike most other frog species, D. branneri can breed in both temporary and permanent pools allowing it to inhabit a wide variety of habitats leading to its wide distribution.[8]
