A new and threatened island-dwelling species of Cycloramphus (Anura : Cycloramphidae) from southeastern Brazil

We describe a new species of Cycloramphus of the eleutherodactylus group from the Ilha dos Alcatrazes, southeastern Brazil, with descriptions of advertisement and territorial calls and notes on natural history. Additionally, we describe the advertisement and territorial calls of C. eleutherodactylus. The new species is diagnosed by the following set of characters: snout truncate in lateral and dorsal views; head wider than long; eyes protruding; tibia shorter than thigh; and distinct advertisement call. The new species is known from a single population on the Ilha dos Alcatrazes, a 149 ha island about 35 kin off São Paulo State coast where these frogs are scattered in a small valley. The very restricted range of the new species of Cycloramphus and the declining quality of its habitat qualify this frog as critically endangered.

Caracterização morfológica, perfil químico, atividade biológica e conservação in situ do gênero Lychnophora Mart. (Asteraceae: Vernonieae: Lychnophorinae), Brasil

Many people who live in the cerrado regions use plant species for therapeutic purposes. However, due to intensive extraction of some species, native botanical populations are at risk of disappearing or suffering a dramatic decrease, such as, for instance, individuals of the Lychnophora genus. This has 24 species distributed into the categories vulnerable, endangered, critically endangered, and possibly extinct. These individuals are known in folk medicine as “arnica” and their leaves and flowers are commonly used as anti-inflammatory, analgesic, and healing agents. The chemical profile of the genus is characterized by the presence of sesquiterpene lactones, sesquiterpenes, diterpenes, triterpenes, flavonoids, steroids, polyacetylenes, and caryophyllene derivatives which also have lignans with analgesic activity. Studies with Lychnophora species show significant results with regard to their biological activities against Leishmania amazonensis, Staphylococcus aureus, and Tripanosoma cruzi. Therefore, this study aimed to perform a survey of the morphology, chemical composition, and biological activity, as well as the use and current conservation status of the Lychnophora genus in Brazil.
