“…We selected four anuran species that are associated with forested habitats (or with their borders)-either with different forest physiognomies in the Atlantic Forest or with gallery forests along streams and rivers in the Cerrado (Brasileiro et al 2005;Santos et al 2009;Brassaloti et al 2010;Maffei et al 2011). Hypsiboas faber and Itapotihyla langsdorffii have wide geographic ranges throughout the different eco-regions in the Atlantic Forest (moist forests or semideciduous/deciduous forests; see .…”

“…In the present study, we want to explore the extent to which habitat loss influences the species distribution and when it culminates in a total exclusion of the species in a given area, thus redefining its geographic limits. Then, we selected four anuran amphibians that are known to predominantly occur in pristine habitats of the Atlantic Forest and Cerrado hotspots (Brasileiro et al 2005;Santos et al 2009;Brassaloti et al 2010;Maffei et al 2011), but alternatively have not been recorded in some intensively impacted areas relatively close to preserved ones (Vasconcelos and Rossa-Feres 2005;Santos et al 2007;Rossa-Feres et al 2012). Santos et al (2009) emphasized that the four anurans selected may have been affected by habitat loss in one of the most impacted Brazilian areas, an area which has experienced land conversions to agricultural and pasture systems.…”

Habitat loss and fragmentation exert unquestionable negative effects in a wide range of taxa on both regional and local scales. However, there is a debate over whether habitat change impacts geographic species distribution. We assess how habitat loss restricts large‐scale species distribution on a geographic scale for four South American anurans that are known to occur in well conserved habitats, yet which are absent in others that are close by and more degraded. We used occurrence records of each species in Brazil and performed different modeling algorithms to compare ensemble distribution models generated by two different sets of predictors: a climate‐only versus a climate‐habitat procedure. We found that the distribution area predicted by the climate‐only procedure was larger than that of the climate‐habitat procedure for all species. The areas not predicted by the climate‐habitat but predicted by the climate‐only procedure for all species are commonly located in inland areas in southeastern Brazil, which coincides with areas that have suffered the most from habitat loss in the country. Plotting the predictions against well‐surveyed areas where the species have not been recorded, we found evidence that habitat loss may have restricted the current geographic ranges of Hypsiboas faber and Rhinella ornata. Finally, modeling approaches incorporating habitat landscape metrics, particularly for habitat‐specialist species, may be a helpful tool for identifying areas that harbored these species before deforestation took place.

“…The coexistence of several anuran species is possible due to the exploitation of microhabitats with distinct characteristics (Cardoso et al 1989, Pombal Jr. 1997, Vasconcelos & RossaFeres 2005, Kopp & Eterovick 2006, Maffei & Jim 2011, where the occupation of different sites of reproduction by synchronopatric species of anurans can function as a mechanism of isolation (Andrade 1994, Á vila & Ferreira 2004, Vieira et al 2007. However, other factors may have an influence in species segregation, such as differentiation in advertisement calls (Pombal Jr. 1997), morphological and behavioral features (Crump 1974, Toft 1985, historical factors (Eterovick & Fernandes 2001), seasonality, habitat and predation (Eterovick & Sazima 2000) and stochastic processes (Bonner et al 1997).…”

In this study, we report the temporal occurrence and habitat and microhabitat use by anurans in two areas located in one highland marsh (brejo-de-altitude) in northeastern Brazil. Fieldwork was carried out between September 2011 and September 2012. The recorded anurans belong to 14 species distributed in five families: Hylidae (six), Leptodactylidae (five), Bufonidae, Odontophrynidae and Pipidae (one each). Vocalization activity was seasonal and concentrated in the wetter and warmer months, but correlated to rainfall only in the top in the Chapada do Araripe. Richness and abundance of calling anurans were lower in the humid forest of the slope than in Cerradão area in the top of the Chapada do Araripe. Scinax x-signatus vocalized during nine months, and along with Dendropsophus soaresi, Phyllomedusa nordestina and Physalaemus cuvieri presented the longest periods of vocalization with the highest number of species vocalizing in at the height of the rainy season. Males were recorded vocalizing in nine different microhabitats, Adenomera sp. uses leaf litter and P. cuvieri the edge of water bodies as calling site both two sampled areas. Differences in richness and abundance of anurans between the two habitats are probably due to physical characteristics, such as presence of lentic environments. Keywords: Anurofauna, microhabitat use, seasonality. Resumo: Neste estudo são descritas a ocorrência temporal e o uso de habitat e microhabitat dos anuros de duas localidades em uma área de brejo de altitude no nordeste do Brasil. As amostragens foram realizadas entre setembro de 2011 e setembro de 2012. Foram registrados anuros pertencentes a 14 espécies distribuídas em cinco famílias: Hylidae (seis), Leptodactylidae (cinco), Bufonidae, Odontophrynidae e Pipidae (uma cada). A atividade de vocalizac¸ã o foi sazonal e concentrada nos meses mais ú midos e quentes, mas correlacionada somente com as chuvas no topo da Chapada do Araripe. A riqueza e abundâ ncia de anuros vocalizando foram menores na floresta ú mida da encosta que na á rea de Cerradão do topo da Chapada do Araripe. Scinax x-signatus vocalizou durante nove meses, e juntamente com Dendropsophus minutus, D. soaresi, Phyllomedusa nordestina e Physalaemus cuvieri apresentou os períodos de vocalizac¸ão mais prolongados, com maior abundancia de indivíduos vocalizando no ápice do período chuvoso. Machos de anuros foram registrados vocalizando em nove microhabitats diferentes, Adenomera sp. utiliza serrapilheira e P. cuvieri a margem dos corpos d'á gua como sítios de vocalizac¸ão em ambas áreas amostradas. Diferenc¸as na riqueza e abundâ ncia de anuros entre os dois habitats estudados estão associadas às características estruturais dos mesmos, como a presenc¸a de ambientes lênticos. Palavras-chave: Anurofauna, uso do micro-habitat, sazonalidade.

“…The Cerrado biome is the second largest Brazilian plant formation, being quite heterogeneous and peculiar, with a valuable chemical arsenal (Maffei et al, 2011;Maracahipes et al, 2011). Among the agricultural activities developed in this biome, livestock farming currently occupies the largest area (Rodrigues and Miziara, 2008).…”

Phytochemical Profile of Pasture Weeds from the Brazilian Cerrado

et al. 2019

The great diversity of plant species in pastures of the Brazilian Cerrado with distinct ecophysiological characteristics indicates the possibility of finding, in the cellular content of this flora, chemical compounds with potential for use in agriculture and human and animal health. Three steps are necessary to prove this hypothesis: phytochemical prospecting, characterization of secondary metabolites, and studies on the biological activities of these metabolites present in these plants.The chemical profile of secondary metabolites present in five species of the Brazilian Cerrado (Davilla elliptica, Remijia ferruginea, Luehea paniculata, Anacardium occidentale, and Acosmium dasycarpum) was traced in this research. These plant species were collected in pasture areas of Felício dos Santos, Minas Gerais. The samples were dried and submitted to two types of extract (ethanolic and hexanic). By using specific chemical reactions, the presence of coumarins, triterpenes/steroids, and anthracenosides was observed in the hexanic extracts, while the presence of alkaloids, triterpenes/steroids, flavonoids, tannins, reducing compounds, and anthocyanins was observed in the ethanolic extracts. The species presented diverse classes of compounds. However, triterpenes/steroids, tannins, reducing compounds and anthocyanins were found in all species, being the use of the solvent ethanol the most efficient in extracting the compounds. The species D. elliptica presented the highest number of classes of compounds. The widespread application in folk medicine justifies further studies on the biological activity of different metabolites in agriculture and health areas.
