Use flexibility of perch types by the branch-camouflaged Common Potoo (Nyctibius griseus): Why this bird may occasionally dare to perch on artificial substrates
Cestari, César
; Gonçalves, Cristina S. ; (Wilson Journal of Ornithology, 2018) [Artigo]
Animal species gain protection against visually oriented predators when they choose a suitable substrate that maximizes camouflaging. The choice of appropriate substrate may be particularly important during the brooding ... -
Droplet bubbling evaporatively cools a blowfly
; ; Von Zuben, Claudio J.; Andrade, Denis V. (Scientific Reports, 2018) [Artigo]
Terrestrial animals often use evaporative cooling to lower body temperature. Evaporation can occur from humid body surfaces or from fluids interfaced to the environment through a number of different mechanisms, such as ... -
Ortalis remota: A forgotten and critically endangered species of chachalaca (Galliformes: Cracidae) from Eastern Brazil
; ; Cestari, César; ; (Zootaxa, 2017) [Artigo]
The habits and general behaviour of the chachalacas (Ortalis spp.) in the Neotropics are well known. However, the validity and even the diagnoses of some taxa are poorly studied, and this may jeopardize the conservation ... -
Comparative analysis based on replication banding reveals the mechanism responsible for the difference in the karyotype constitution of treefrogs ololygon and scinax (arboranae, hylidae, scinaxinae)
Gruber, Simone Lilian; de Oliveira, Gabriela Isabela Gomes ; Silva, Ana Paula Zampieri ; Narimatsu, Hideki ; Haddad, Célio Fernando Baptista ; Kasahara, Sanae (Comparative Cytogenetics, 2017) [Artigo]
According to the recent taxonomic and phylogenetic revision of the family Hylidae, species of the former Scinax catharinae (Boulenger, 1888) clade were included in the resurrected genus Ololygon Fitzinger, 1843, while ... -
Trade-offs in male display activity with lek size
Cestari, César; ; Pizo, Marco Aurélio (PLoS ONE, 2016) [Artigo]
In lek mating systems, males aggregate and defend arenas where they display for females; females select and mate with a male and then solely raise their offspring. Generally, female visits and copulations increase and ... -
Evolutionarily significant units of the critically endangered leaf frog Pithecopus ayeaye (Anura, Phyllomedusidae) are not effectively preserved by the Brazilian protected areas network
(Ecology and Evolution, 2017) [Artigo]Protected areas (PAs) are essential for biodiversity conservation, but their coverage is considered inefficient for the preservation of all species. Many species are subdivided into evolutionarily significant units (ESUs) ... -
Polydomy in the ant Ectatomma opaciventre
(Journal of insect science (Online), 2014) [Artigo]Tropical ants commonly exhibit a hyper-dispersed pattern of spatial distribution of nests. In polydomous species, nests may be satellites, that is, secondary structures of the main nest, where the queen is found. In order ... -
Preliminary assessment of mitochondrial variation in the insular endemic, biogeographically enigmatic noronha skink, trachylepis atlantica (Squamata: Scincidae)

Amphibian parasites of the Order Dermocystida (Ichthyosporea): current knowledge, taxonomic review and new records from Brazil
; ; ; Baêta, Délio; Sabbag, Ariadne Fares ; ; ; Haddad, Célio F. B. ; ; et al. (Zootaxa, 2018) [Resenha]
Amphibian parasites of the Order Dermocystida (Ichthyosporea) are widespread pathogens known mainly from Europe and North America, which cause primarily a disease of skin and subcutaneous tissue in their hosts. The taxonomy ... -
Molecular phylogeny of Ischnocnema (Anura: Brachycephalidae) with the redefinition of its series and the description of two new species
Taucce, Pedro P.G.; ; ; ; ; Haddad, Célio F.B. (Molecular Phylogenetics and Evolution, 2018) [Artigo]
We present a new phylogenetic hypothesis for Ischnocnema, a Neotropical brachycephaloid genus of ground-dwelling direct-developing frogs. We performed Bayesian inference, maximum likelihood, and maximum parsimony analyses ... -
Morphology of setae on the coxae and trochanters of theraphosine spiders (Mygalomorphae: Theraphosidae)
Lima, Arthur Galleti; Guadanucci, José Paulo Leite (Journal of Arachnology, 2018) [Artigo]
Mygalomorphae spiders have several cuticular structures, such as stridulating, sensory and urticating setae, which offer great potential for phylogenetic studies. Spiders of the subfamily Theraphosinae have stridulating ... -
Ichthyofauna diet changes in response to urbanization: the case of upper Paranapanema River basin (Brazil)
; da Silva Gonçalves, Cristina; (Urban Ecosystems, 2018) [Artigo]
Alterations in stream environments can alter fish food availability, but there is little research data related to the impacts of urbanization on fish diets in tropical streams. Thus, we sought to compare the diet of ten ... -
Trophic structure of coastal freshwater stream fishes from an Atlantic rainforest: evidence of the importance of protected and forest-covered areas to fish diet
da Silva Gonçalves, Cristina; de Souza Braga, Francisco Manoel ; Casatti, Lilian (Environmental Biology of Fishes, 2018) [Artigo]
The role of riparian forests in the functioning of aquatic ecosystems is well known, and they are recognized as an important food source for riverine fauna. This study investigates the trophic structure of coastal freshwater ... -
Maternal provisioning by foam-nesting frogs of the genus Physalaemus (Anura, Leptodactylidae) in contrasting environments
Pupin, Nadya C.; Haddad, Célio F.B. ; Prado, Cynthia P.A. (Amphibia Reptilia, 2018) [Artigo]
In some environments prevailing conditions are unpredictable, thus anuran species use bet-hedging strategies and produce eggs of varied sizes. We investigated whether four species of Physalaemus (two from open, two from ... -
Chromosome evolution in Cophomantini (Amphibia, Anura, Hylinae)
; ; ; ; ; ; ; Gazoni, Thiago; ; et al. (PLoS ONE, 2018) [Resenha]
The hylid tribe Cophomantini is a diverse clade of Neotropical treefrogs composed of the genera Aplastodiscus, Boana, Bokermannohyla, Hyloscirtus, and Myersiohyla. The phylogenetic relationships of Cophomantini have been ... -
