DISTRIBUTION OF TADPOLES WITHIN AND AMONG BRAZILIAN STREAMS: THE INFLUENCE OF PREDATORS, HABITAT SIZE AND HETEROGENEITY
- P. Eterovick, Izabela M. Barata

We studied the composition and richness of local tadpole assemblages in several streams at a forest site in southeastern Brazil. We initially focused on species distributions within streams,…
Lack of phylogenetic signal in the variation in anuran microhabitat use in southeastern Brazil

It is suggested that microhabitat use is a plastic and variable trait, overcoming phylogenetic signal in tadpoles, and not a good predictor of phylogeny, but it may be a very interesting subject to study natural selection and adaptation.
A new species of Crossodactylodes (Anura: Leptodactylidae) from Minas Gerais, Brazil: first record of genus within the Espinhaço Mountain Range.

The new species inhabits rupicolous bromeliads in open areas of rocky fields, and is recorded in altitudes between 1836 and 2062 m above sea level, extending the genus distribution for about 325 km northwest from where it was known.

Although the number of studies discerning the impact of climate change on ecological systems continues to increase, there has been relatively little sharing of the lessons learnt when accumulating…
Predictors of Abundance of a Rare Bromeliad-Dwelling Frog (Crossodactylodes itambe) in the Espinhaço Mountain Range of Brazil
- Izabela M. Barata, E. P. Silva, R. Griffiths
- Environmental ScienceJournal of Herpetology
- 23 July 2018
The first species assessment and evaluation of threat categories for this poorly known Crossodactylodes itambe is provided, finding that bromeliad size, volume of central tank, and presence/absence of invertebrates and of water influenced frog abundance.
The power of monitoring: optimizing survey designs to detect occupancy changes in a rare amphibian population
- Izabela M. Barata, R. Griffiths, M. Ridout
- Environmental ScienceScientific Reports
- 28 November 2017
A tropical bromeliad-dwelling frog is used as a model system to explore a cost-effective sampling design that optimizes the chances of detecting a population decline and estimates occupancy and detectability with good precision.
Assessing the conservation value of secondary savanna for large mammals in the Brazilian Cerrado
- G. B. Ferreira, J. Ahumada, B. Collen
- Environmental Science
- 21 June 2017
Debate about the conservation value of secondary habitats has tended to focus on tropical forests, increasingly recognizing the role of secondary forests for biodiversity conservation. However, there…
The Tadpole of the Microendemic, Bromeligenous Crossodactylodes itambe (Anura, Leptodactylidae) from the Endangered ‘Campo Rupestre’ of Southeastern Brazil, with Additional Comments on Natural History
- M. T. T. Santos, T. Pezzuti, Izabela M. Barata, F. Leite, P. Garcia
- BiologySouth American Journal of Herpetology
- 26 April 2017
The tadpole of C. itambe differs from the previously described Crossodactylodes tadpole in total length, origin of dorsal fin, development of tail musculature, spiracle position, absence of inner wall of spiracle and shape, and direction of vent tube.
Comparison of eDNA and visual surveys for rare and cryptic bromeliad-dwelling frogs
- Izabela M. Barata
- Environmental Science
- 2021
Surveys of rare or cryptic species may miss individuals or populations that are actually present. Despite the increasing use of environmental DNA (eDNA) analysis to survey species in ponds, rivers,…
Downscaling the Gap: Protected Areas, Scientific Knowledge and the Conservation of Amphibian Species in Minas Gerais, Southeastern Brazil
