13. Influence of rainfall and temperature on the spermatogenesis of Leptodactylus macrosternum (Anura: Leptodactylidae)
ABSTRACT In the semi-arid environment, the reproductive success of anurans depends on adaptations in their life cycle, which synchronizes with ideal environmental conditions to maximize the number of offspring. In this study changes in the histological and morphometric aspects of the testes of Leptodactylus macrosternum Miranda-Ribeiro, 1926 are characterize

14. ANUROS DEL NORTE DE LOS ANDES: PATRONES DE RIQUEZA DE ESPECIES Y ESTADO DE CONSERVACIÓN
ABSTRACT Knowledge of Andean anurans is constantly increasing; for this reason, it needs an update. We reviewed scientific literature and museum records to determine the species richness of anurans in the northern Andes and their conservation status based on the IUCN categories. The northern Andes harbor 740 species of anurans, belonging to 13 families and 6

15. Acoustic communication in two species of the Hypsiboas albopunctatus group (Anura: Hylidae) in sympatry and allopatry
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 paramete

17. Synergic effects between ocellatin-F1 and bufotenine on the inhibition of BHK-21 cellular infection by the rabies virus
Abstract Background Rabies is an incurable neglected zoonosis with worldwide distribution characterized as a lethal progressive acute encephalitis caused by a lyssavirus. Animal venoms and secretions have long been studied as new bioactive molecular sources, presenting a wide spectrum of biological effects, including new antiviral agents. Bufotenine, for i

18. How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?
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 b

19. Evolution of erythrocyte morphology in amphibians (Amphibia: Anura)
ABSTRACT We compared the morphology of the erythrocytes of five anurans, two toad species - Bufo gargarizans (Cantor, 1842) and Duttaphrynus melanostictus (Schneider, 1799) and three frog species - Fejervarya limnocharis (Gravenhorst, 1829), Microhyla ornata (Duméril & Bibron, 1841), and Rana zhenhaiensis (Ye, Fei & Matsui, 1995). We then reconstructed the

20. Diversidad, distribución espacio-temporal y turnos de vocalización de anuros (Amphibia, Anura) en un área ecotonal del nordeste de Argentina
ABSTRACT Studies on diversity and natural history of anuran communities are basic to distinguish natural fluctuations from those due to human impacts (a key tool in conservation programs), to assess the role they play in ecosystems dynamics and to allow comparison of diversity gradients. With those objectives, this paper analyzes diversity, temporal and spat

21. Cytogenetic studies in six species of Scinax (Anura, Hylidae) clade Scinax ruber from northern and northeastern Brazil
Scinax species are still underrepresented in cytogenetic studies, mainly with respect to populations from northeastern and northern Brazil. In this study, we provide new chromosomal information on Scinax boesemani, S. camposseabrai, S. garbei, S. pachycrus, S. trilineatus and S. x-signatus, all belonging to clade S. ruber. They were collected at two location

22. Advertisement call of Dendropsophus microps (Anura: Hylidae) from two populations from southeastern Brazil
In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of th

23. Richness, breeding environments and calling activity of the anurofauna of the lower moa river forest, state of Acre, Brazil
In state of Acre, most anuran research has been carried out in areas of terra firme, whereas alluvial forests remain relatively unexplored. We document the richness, breeding environments and calling season of the anurans of the Lower Moa River in the Alto Juruá (state of Acre), a region considered to harbor high biodiversity. Sampling was conducted in two

24. Los anfibios en la medicina popular española, la farmacopea de Plinio y el Dioscórides
This article presents a list of medical remedies based on the use of amphibians in Spanish popular medicine and in the classical world. It provides an overview of bibliography relative to folklore studies, ethnographic work and research on social or medical anthropology. It documents a total of 113 remedies and the use of nine species of amphibians, two from
