Abstract Research on environmental perception is essential for the understanding of individuals’ relations and expectations towards natural environments. Here, we evaluated the perception of high school students on exotic and native species in Brazil. We interviewed 371 students from two high schools located in the state of Goiás, one with and one without a protected area within its premises. Students needed to identify native and exotic species and to indicate species origin. We used a t-test to evaluate differences between students’ scores regarding the correctness of species origin and also ANOVA to assess whether these scores varied among taxonomic groups. Students identified exotic species better than native ones. Students better identified exotic mammals, fishes, and birds than native ones. We found there were no significant relationships of students’ knowledge of species’ origins with socioecological factors. Students’ perceptions of exotic and native species were low and focused on charismatic large-bodied species. We suggest that students are encouraged to expand their knowledge of local biodiversity. Teachers, local schools, and policymakers are essential to achieve this aim. A more diverse methodology for teaching, including new technologies and citizen-science projects, can help establish a genuine interest of local biodiversity students.

ABSTRACT Anuran males and females adopt different reproductive and behavioral strategies in different contexts. We investigated the reproductive ecology and territorial behavior of the treefrog Boana goiana (B. Lutz, 1968) from the Brazilian Cerrado. We hypothesized that competitor density/proximity would increase the behavioral responses of B. goiana males, and that mating would be assortative. We also tested if the number of eggs correlates with female size and if there is a trade-off between clutch size and egg size. We conducted two territoriality experiments to test the effects of male size, competitor proximity and competitor density. Larger males called more in the presence of a second male. In the second experiment, the largest males emitted more calls and the distance to the nearest male increased as resident males called more. In both experiments, the number of calls was influenced by either male size or spacing between males. Some males behaved as satellites, probably to avoid fights. Our analyses indicate that females choose males with similar sizes to their own, corroborating our hypothesis of size-assortative mating. We found no relationships between female size and clutch size/volume, and between egg size and number of eggs per clutch. We also report multiple spawning for this species. The low incidence of physical combats and the spacing pattern indicate that this species relies almost solely on calls to resolve contests, which could be explained by low motivation, or simply because males avoid combats to decrease injury risks. Thus, acoustic or even multimodal communication seems crucial for social interactions of B. goiana.

Abstract Bacterial colonization plays a key role on the pathogenesis of peri-implantitis and may be influenced by titanium surface topography. The aim of this in vitro study was to evaluate the influence of titanium topography after fluoride ions deposition in the bacterial colonization. Machined (M), double acid-etched (DE) and double acid-etched surface with fluoride ions deposition (Nano F-) were analyzed by scanning electron microscopy, contact angle and roughness (Ra). Streptococcus mutans viability was quantified by Live/Dead Baclight bacterial viability kit. The mean Ra/contact angle values were 0.20 μm/69.13°, 0.53 μm /92.82° and 0.56 μm/94.33° for M, DE and Nano F-, respectively. M surface presented significantly lower live bacterial counts when compared to the Nano F- surface (p=0.007). The dead bacteria count was higher on the Nano F- surface (p=0.001) than on the M and DE surfaces. Crystalline deposition of fluoride ions (Nano F-) promoted an increase in dead bacteria on the tested titanium surface.

ABSTRACT: The process of integrating an international, intercultural, and global dimension into the purpose, functions or delivery of education defines the Internationalization of Higher Education (IoHE). Due to lack of resources for education, internationalization at home (IaH) has gained popularity. Internationalization of Higher Education involving Information and Communication Technology (ICT) opens opportunities for innovative learning approaches across nations and cultures. The purpose of this paper is to analyze the scientific publications of recent years on digital learning platforms related to IoHE. For this, a descriptive exploratory research was conducted based on an integrative literature review. Analysis of this field shows that e-learning platforms have boosted online and distance learning and diversified the IoHE landscape. Collaborative Online International Learning (COIL) programs emerge as part of IaH and reflect the growing link between ICTs, social media, and internationalization. The concept of virtual internationalization can be used as a conceptual framework to promote IoHE.

ABSTRACT Bioacoustics is an effective way of recording detailed data during population surveys and monitoring. In the present study, we used an automated digital recorder (ADR) to describe the temporal variation in the calling activity of Scinax fuscomarginatus (Lutz, 1925) in central Brazil. We also evaluated the role of climatic variables (air temperature and precipitation) on calling activity by using a Generalized Additive Model (GAM). We conducted the recordings at five ponds in the Cerrado savanna of Rio Verde Municipality, in Goiás state between November 2013 and October 2014. The analysis of the 43.2 hours of acoustic recording showed that S. fuscomarginatus has a prolonged breeding pattern. The ADR provides a fine-scale description of the nocturnal calling pattern, as well as the oscillations between the rainy and dry seasons. The results of the analytical model also indicate that calling patterns were related to minimum (but not maximum) air temperatures and precipitation, which may be related to their reproductive and thermoregulatory requirements. Based on these findings, we conclude that the ADR method has potentially valuable applications for the collection of data on the natural history of anuran species, as well as supplying important insights for conservation initiatives.

ABSTRACT The anuran skin characteristically has different types of glands, most of which are microscopic and are spread throughout the skin. Some species have specialized regions where glands agglomerate, forming macroglands. The description of the external morphology of Ololygon centralis (Pombal & Bastos, 1996) revealed the presence of an inguinal gland. Ololygon centralis is the only species of the genus that has a macrogland. The present study found these inguinal macroglands to be present only on male specimens, thus characterizing it as a sexually dimorphic skin gland. Microscopic analysis revealed that these glands are composed of many syncytial units involved by myoepithelial cells. The center of the syncytium is full of a proteinaceous secretion with a basic pH and the absence of sugar residues. Similar glands observed in other anuran species have been associated with pheromone production, suggesting that the inguinal glands described for O. centralis males may have a similar function.

Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Brazilian Cerrado. Chromosome preparations for both species were stained with Giemsa for morphological analyses and then impregnated by the Ag-NOR method for localization of the nucleolar organizer region (NOR). Both species had 24 chromosomes, as confirmed by meiotic analyses, which showed 12 bivalents. Chromosome morphologies presented the same pattern for Scinax and Ololygon compared to species already karyotyped in both genera. The NOR was interstitially located in the long arm of pair 7 in S. constrictus, whereas in O. centralis it was found near the centromere in the long arm of pair 1, thus diverging from what is commonly found for other Ololygon species. Therefore, we provide the first description of the karyotype of O. centralis and the first report of the localization of the NOR for the karyotype of both species. Our study increases the cytogenetic knowledge in species of the genera Scinax and Ololygon, and provide support for further studies on the taxonomy, ecology, and evolution of hylid anurans.

ABSTRACT Amphibians inhabiting agricultural areas are constantly exposed to large amounts of chemicals, which reach the aquatic environment during the rainy season through runoff, drainage, and leaching. We performed a comet assay on the erythrocytes of tadpoles found in the surroundings of agricultural fields (soybean and corn crops), where there is an intense release of several kinds of pesticides in different quantities. We aimed to detect differences in the genotoxic parameters between populations collected from soybeans and cornfields, and between them and tadpoles sampled from non-agricultural areas (control group). Tadpoles collected from ponds located at soybean fields had significantly more DNA damage, followed by tadpoles collected from cornfields. In contrast, animals sampled from non-agricultural areas had the lowest incidence of DNA damage. In addition, we found a negative correlation between the parameters of the comet assay and the area of the ponds surrounding soybean. This correlation indicates a possible dilution effect in the concentration of pesticides. Finally, Physalaemus cuvieri Fitzinger, 1826 seems to be a good bioindicator for detecting the genotoxic effects of field agricultural insecticides; therefore, we suggest that this species should be used in environmental biomonitoring studies, since it is common and abundant where it occurs.

ABSTRACT Tropical anuran communities are very diverse. Nevertheless, much of their ecological and historical processes remain unknown. Bioacoustical studies are important to help to solve these puzzles. In the present study we examined the effect of environmental (air temperature and humidity) and morphological (body size) attributes on the acoustic parameters of two frogs of the Hypsiboas albopunctatus species group (H. albopunctatus and H. paranaiba ) living in sympatry and allopatry in the Brazilian cerrado. We also investigated if the presence of one species influences the spatial distribution or vocal behaviour of the other. We found H. albopunctatus and H. paranaiba males emitting advertisement and aggressive calls in sympatry and allopatry. Although the calling behavior of H. paranaiba did not differ in sympatry and allopatry, differences were noted for H. albopunctatus . Bioacoustics is the main form of communication in anurans, and is one of the best ways to discriminate among species. Variations in the calling behavior of males and what drives these variations in both species is central to better understand the processes of specific recognition and female attraction.

ABSTRACT Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals. Herein, we used playback experiments to test whether males of Hypsiboas goianus (Lutz, 1968) change their vocal behavior in response to conspecific advertisement calls. Specifically, we used different field playback experiments in which we modified the time interval between advertisement calls to simulate males with distinct states of motivation (Sequence A and B). We did not observe differences in the acoustic response of males of H. goianus between the two types of field playback experiments. On the other hand, we observed that H. goianus males reduce the dominant frequency of the advertisement call and increase the rate of aggressive calls in response to a conspecific competitor. Our results suggest that the acoustic plasticity observed in males of H. goianus represents an aggressive response that allows repelling conspecific individuals.

O presente artigo, baseando-se em Marcuse, critica a atual globalização e sua rubrica a um modelo dito consensual aos valores do mercado, o homem unidimensional. Este, pretendendo ser o pensamento único, se firmará não só por ditar as condições concretas e subjetivas para todos, mas também por reproduzi-las pelo Estado, notadamente, através das instituições sociais que, apresentando-se como uma rede hegemônica, tenderão a reproduzir essa unidimensionalidade pelo planeta. Sob tempos de quase absoluto consenso em prol desses valores, o artigo reflete sobre as possíveis rupturas ao referido modelo.

This article, based on Marcuse, criticizes the current movement of globalization and its sustenance of a model considered consensual to market values, the one-dimensional man. This, with the intention of being the sole form of thinking, establishes itself not only by determining the concrete and subjective conditions for everyone, but also by reproducing them through the State, notably, through social institutions that, by presenting themselves as part of a hegemonic network tend to reproduce this one dimensionality throughout the planet. Under times of near absolute consensus in support of these values, the article reflects on possible breaks in this model. '

A diversidade biológica e os processos ecológicos do bioma Cerrado ainda são pouco conhecidos. Neste estudo são apresentadas informações acerca da estrutura da anurofauna do município de Barro Alto, estado de Goiás (Brasil Central). Cinco corpos d'água foram amostrados entre os anos de 2007 a 2010 (outubro-março), três deles associados à área florestal e dois associados à área aberta. Registraram-se 39 espécies de anuros, caracterizados como especialistas de hábitat aberto, florestal ou generalistas. A curva de acumulação de espécies apresentou a formação de uma assíntota, evidenciando que as técnicas e esforço de amostragens foram adequados para se estimar a riqueza de espécies de anuros na região. A riqueza foi influenciada pela umidade e temperatura, já que a maioria das espécies se reproduz na estação quente e chuvosa. Diferenças significativas na composição de espécies entre os sítios reprodutivos de áreas florestais e abertas foram registradas. A fauna de anuros no Cerrado parece ser constituída a partir da heterogeneidade horizontal dos hábitats no espaço. Assim, hábitats contrastantes no espaço são importantes para a manutenção da riqueza da anurofauna, e portanto, relevantes em termos conservacionistas.

The biological diversity and ecological processes in Cerrado biome are still poorly understood. Herein we present information about anuran species of the municipality of Barro Alto, state of Goiás (Central Brazil). Five water bodies were sampled between the years 2007 and 2010 (October-March), three of them associated with forested area and two with open areas. We recorded 39 anuran species, characterized as open habitat specialists, forest habitat specialists and generalists. The rarefaction curve shows an asymptote formation, which demonstrates adequate effort and sampling techniques to assess the species richness of the region. Species richness was influenced by air humidity and temperature, since most of the species reproduce in the rainy season. We found significant differences in species composition between breeding sites in open and forested areas. The anurofauna in Cerrado seems to be formed from habitat's horizontal heterogeneity in space. Thus, contrasting habitats in space are important for maintaining the anuran richness, and therefore relevant in conservation terms.

BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being preyed or parasitized. The most abundant predator in our sampling areas was the diving beetle larvae. We observed a static and escape behavior of tadpoles when in close proximity to predators and constant movements in E. bicolor tadpoles, which can be advantageous for invertebrate predators. Parasitism events included D. aff. minutus, S. fuscovarius,andE. bicolor tadpoles that were infected by a single leech. The ectoparasites anchor the posterior sucker on the host tadpole during the blood feeding. CONCLUSIONS: Even isolated reports of ecological interactions are important for understanding ecological communities and the impacts of parasites and predators on tadpoles' populations. Additionally, these interactions can help to understand the ecology behavior of the organisms.

O Cerrado é uma savana tropical que abriga uma anurofauna muito diversa, sendo estimado de 209 espécies à 271 espécies conhecidas, das quais a metade (51%) são endêmicas. Neste trabalho, apresentamos o inventário da anurofauna da Reserva Extrativista Lago do Cedro (RELC), noroeste do estado de Goiás. Ao todo, registramos 36 espécies de anuros, distribuídas em cinco famílias, das quais cinco espécies são endêmicas do Cerrado. A alta riqueza de espécies encontrada pode ser explicada pela heterogeneidade de habitats, promovida pelas diferentes fitofisionomias dentro da unidade de conservação. A riqueza de espécies e a representatividade por família apresentam valores semelhantes aos encontrados em outras taxocenoses no Cerrado, com a anurofauna local formada por espécies generalistas e de ampla distribuição. As famílias com maior diversidade de espécies foram Hylidae e Leptodactylidae, padrão frequentemente encontrado nas assembleias neotropicais. A RELC é uma importante unidade de conservação do Cerrado, servindo de abrigo para populações de anuros, sendo representativa da diversidade de anfíbios no bioma, e apresentando localização estratégica devido a posição central com relação a áreas de preservação na bacia do Araguaia.

The Cerrado is a tropical savannah with a diversified anuran assemblage, with 209 to 271 known species, of which approximately 51% are endemic. In this study, we report results of an anuran survey performed in the Extractivist Reserve of the Lago do Cedro, located in the northwestern region of the state of Goiás, Brazil. In this area, we recorded 36 anuran species, distributed in five families, from which five species are Cerrado endemics. This high species richness found in the Extractivist Reserve of the Lago do Cedro could be explain by the different vegetational types within the reserve boundaries that promote a high local heterogeneity. Species richness and representativeness per family are similar to other assemblages reported for different areas in the Cerrado domain, being the local anuran assemblage composed by generalist and widely distributed species. The families Hylidae and Leptodactylidae are the most diversified in the studied area, a common pattern found in neotropical assemblages. The Extractivist Reserve Lago do Cedro is an important area for Cerrado conservation because of the anuran diversity and geographic location, which allows the connection among other protected areas within the Araguaia basin.
