Osteología craneal comparativa en el género Sclerurus (Passeriformes: Furnariidae)
(Revista de Biologia Tropical, 2016) [Artigo]The Furnariidae encompasses 293 species and has been recognized as an example of continental adaptive radiation. They inhabit biomes from deserts to humid forests at all strata and show morphological heterogeneity unparalleled ... -
First record of Scinax berthae (Anura: Hylidae) for the state of Minas Gerais, Southeastern Brazil
(Herpetology Notes, 2016) [Artigo] -
Satellitome analysis illuminates the evolution of ZW sex chromosomes of Triportheidae fishes (Teleostei: Characiformes)
(Chromosoma, 2022) [Artigo]Satellites are an abundant source of repetitive DNAs that play an essential role in the chromosomal organization and are tightly linked with the evolution of sex chromosomes. Among fishes, Triportheidae stands out as the ... -
Environmental conditions drive vocal variation in the scaled dove (Columbina squammata)
(Ornithology Research, 2022) [Artigo]Variations in communication systems profoundly affect bird evolution. Vocalizations mediate species recognition and therefore intra-specific variation may lead to reproductive isolation, ultimately resulting in speciation. ... -
Genetic markers indicate that hybrids of Pseudoplatystoma (Siluriformes, Pimelodidae) are reproducing in natural environments in southeastern Brazil
(Biological Invasions, 2022) [Artigo]Due to the constant propagule pressure of invasive species, aquaculture is considered to be one of the principal mechanisms for the introduction of non-native fish species into wild habitats in Brazil. The ongoing expansion ... -
Chromosomal Instability and Origin of B Chromosomes in the Amazonian Glass Tetra Moenkhausia oligolepis (Günther, 1864) (Characiformes, Characidae)
(Cytogenetic and Genome Research, 2021) [Artigo]B chromosomes occur in different species of the small characid fishes of the genus Moenkhausia. These supernumerary elements, that do not recombine with chromosomes of the standard A complement and follow their own ... -
The long trail: A chimera-like fossil crustacean interpreted as decapoda, stomatopoda, amphipoda and finally isopoda
(Rivista Italiana di Paleontologia e Stratigrafia, 2021) [Artigo]The process of interpreting and evaluating a fossil is a difficult task. Isopoda is a species-rich group of peracarid eumalacostracans which represent quite a challenge when found as fossils, independent of whether we are ... -
First cytogenetic characterization of the amazon catfish leiarius marmoratus (Gill, 1870) and its hybrid with pseudoplatystoma reticulatum (eigenmann & eigenmann, 1889)
(Caryologia, 2021) [Artigo]This study reports the first cytogenetic characterization of the Amazonian catfish Leiarius marmoratus (“jandiá”) and its F1 (first generation) hybrid “cachandiá” with Pseudoplatystoma reticulatum (“cachara”). A diploid ... -
Defaunation and changes in climate and fire frequency have synergistic effects on aboveground biomass loss in the brazilian savanna
(Ecological Modelling, 2021) [Artigo]As a result of anthropogenic pressure, three drives are expected to affect Brazilian savannas: an increase in the dry season, more frequent fire events, and defaunation. These drivers are a trigger for biodiversity loss ... -
The b chromosomes of prochilodus lineatus (Teleostei, characiformes) are highly enriched in satellite dnas
(Cells, 2021) [Artigo]B or supernumerary chromosomes are dispensable elements that are widely present in numerous eukaryotes. Due to their non-recombining nature, there is an evident tendency for repetitive DNA accumulation in these elements. ... -
Paleoecologic trends of Devonian Malvinokaffric fauna from the Paraná Basin as evidenced by trace fossils
(Journal of South American Earth Sciences, 2021) [Artigo]The Malvinokaffric Realm is an endemic paleogeographic region that inhabited Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the collapse of this fauna are still debated but seem to be related ... -
Compared cranial osteology of species of Leptoptilus (Lesson, 1831) (Aves, Ciconiidae)
(Comunicata Scientiae, 2019) [Artigo]The species of the Ciconiidae family (Ciconiiformes), commonly known as storks, exhibit a cosmopolite distribution, being represented by swamp birds of medium and large size. The present work aimed to describe minutely and ... -
Phylogeny of the species of Ciconia (Aves, Ciconiidae) based on cranial osteological characteristics
(Comunicata Scientiae, 2018) [Artigo]The Family Ciconiidae currently comprises 19 species distributed primarily in the tropical and sub-tropical regions around the world. Recent studies on phylogeny within the genus and families of birds provided a new ... -
Efeito da Inclusão do Farelo e da Farinha de Semente de Algodão em Rações para Reprodutores de Tilápia do Nilo (Oreochromis niloticus)
(Revista Brasileira de Zootecnia, 1999) [Artigo]This experiment was conducted to evaluate the effect of cottonseed meal and cotton seed flour on the reproductive behavior and on the testis activity of Nile tilapia broodstock. Twenty-five fishes were fed diets containing ... -
The Effect of Toothpastes Containing Natural Extracts on Bacterial Species of a Microcosm Biofilm and on Enamel Caries Development
(Antibiotics, 2022) [Artigo]This study investigated the effects of herbal toothpaste on bacterial counts and enamel demineralization. Thirty-six bovine enamel samples were exposed to a microcosm biofilm using human saliva and McBain saliva (0.2% ... -
Effects of long-term fluoride exposure are associated with oxidative biochemistry impairment and global proteomic modulation, but not genotoxicity, in parotid glands of mice
(PLoS ONE, 2022) [Artigo]Background Fluoride has become widely used in dentistry because of its effectiveness in caries control. However, evidence indicates that excessive intake interferes with the metabolic processes of different tissues. Thus, ... -
Biocompatibility and osteopromotor factor of bovine integral bone—a microscopic and histometric analysis
