This paper presents a study on the viability of the use of tissues of the Leptodactylus ocellatus species (Anura Leptodactylidae) as a bioindicator of metal pollution. The study is based on the determination and correlation of the concentrations of manganese, chromium, zinc, nickel, copper and iron in sediments and tissues (skin, muscles and viscera) of the frog Leptodactylus ocellatus collecte...

A new species of the genus Amazophrynella (Anura, Bufonidae) is described from the departments of Madre de Dios, Cusco and Junin in Peru. An integrative taxonomy approach is used. A morphological diagnosis, morphometrics comparisons, description of the advertisement call, and the phylogenetic relationships of the new species are provided. Amazophrynella javierbustamantei sp. n. differs from oth...

During the revision of this paper, a theoretical section and some results were added from another related paper that was in review at that time and subsequently published as Urteaga et al. (2009). Similarly, some studies were added from Hakkarinen and Han (2008) that we presented at a workshop. During the revision, the authors of this paper failed to refer to Urteaga et al. (2009) and Hakkarine...

Toads of the Bufo peltocephalus Group (Anura: Bufonidae) occur throughout the Greater Antilles (Cuba to the Virgin Islands), a geographic region of relatively high endemicity. Previous morphological and immunological studies suggested that the West Indian toads are a monophyletic lineage derived from Neotropical Bufo but were unable to clarify relationships within the group. We examined the evo...

Flies in the family Corethrellidae Edwards 1932 (Diptera) are known to be attracted to the mating calls of male frogs. For the first time, the hosts of corethrellids were identified to species by analyzing bloodmeals taken from resting female flies. A portion of the cytochrome b gene was amplified and sequenced from blood-engorged flies using vertebrate-specific primers. The flies were collecte...

What determines which spatial axis people use to represent time? We investigate effects of writing direction. English, like Mandarin Chinese in mainland China, is written left to right and then top to bottom. But in Taiwan, characters are written predominantly top to bottom and then right to left. Because being a fluent reader-writer entails thousands of hours of experience with eye and hand mo...

Stynoski et al. introduce the dendrobatids, a charismatic group of frogs known for their colourful and often poisonous skin.
