1. On the distinctive call of a threatened phenotype of Allobates femoralis (Anura: Aromobatidae) and its recognition by allopatric conspecific males
ABSTRACT The brilliant-thighed frog [Allobates femoralis (Boulenger, 1884)]; is distributed across the Amazon basin and aggregates several allopatric evolutionary lineages, some of which present variation in their advertisement calls. In 2009, an unregistered call phenotype was discovered in the region of Altamira and Vitória do Xingu, State of Pará, Brazi

2. 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

3. Advertisement and release calls of Phyllomedusa ayeaye (Anura: Hylidae) with comments on the social context of emission
ABSTRACT Male calls play different roles in anuran social organization, such as spacing, territoriality and female attraction. However, calls and associated behaviors remain poorly described for many anuran species. Here we describe the advertisement and release calls of the tree frog Phyllomedusa ayeaye (Lutz, 1966) and report on the social context of emiss

4. Vocal repertory of Scinax littoreus (Anura: Hylidae) with comments on the advertisement call of the Scinax perpusillus species group
The Scinax perpusillus species group consists of thirteen bromeligenous treefrogs, of which only six have had their acoustic parameters appropriately described. In this work, we present the vocal repertory of Scinax littoreus (Peixoto, 1988) based on recordings obtained from three different populations in the state of Rio de Janeiro, Brazil. Based on our obs

5. Advertisement call propagation and species recognition in anurans: in time and space / Propagação e reconhecimento específico do canto de anúncio de anuros: no tempo e no espaço
This study evaluates the influence of the vegetation structure on the advertisement call propagation and the evolution of acoustic communication in anurans. The first chapter reviews the literature on the effects of vegetation in the advertisement-call transmission, addressing directly or not, the Acoustic Adaptation Hypothesis. The studies found were analyz

6. HISTÓRIA NATURAL DE CROSSODACTYLUS SCHMIDTI GALLARDO, 1961 (ANURA, HYLODIDAE) NO PARQUE ESTADUAL DO TURVO, RIO GRANDE DO SUL / NATURAL HISTORY OF CROSSODACTYLUS SCHMIDTI GALLARDO, 1961 (ANURA, HYLODIDAE) FROM PARQUE ESTADUAL DO TURVO, RIO GRANDE DO SUL
A presente dissertação apresenta informações sobre (1) o canto de anúncio e o canto agressivo de Crossodactylus schmidti, e sobre (2) a dieta da espécie e sua relação com a disponibilidade de presas. O estudo foi conduzido com populações do Parque Estadual do Turvo, localizado na região noroeste do Rio Grande do Sul, Brasil. O parque possui uma á

7. Terapia fonoaudiológica assistida por cães: estudo de casos clínicos
INTRODUCTION: By sharing our routines with animals, they became part of our culture when start to occupy different roles, besides the company. Currently, due to the benefits not restricted to common sense, but also listed from scientific research, they are in clinics, hospitals, schools and many others institutions. These studies gave itself two ways to call

8. Risk stratification with troponin I in patients undergoing myocardial revascularization surgery
OBJECTIVE: To determine the immediate behavior and the prognostic value in terms of late survival of serum troponin I measurement in patients undergoing myocardial revascularization surgery with extracorporeal circulation. METHODS: We studied 88 random patients, 65 (73.8%) of the male sex, who underwent myocardial revascularization surgery with extracorporea

9. Comportamento reprodutivo e comunicação sonora e hyla minuta Peters, 1872 : amphibia, anura, hylidae
The present work was carried out with the central purpose of studying the reproductive behavior of Hyla minuta in the municipality of Campinas, state of São Paulo, Brazil (22º48 S, 47º05 W, 650-700 m alt.). The influence of some abiotic factors (temperature, wind, thunder, moon luminosity, sunset, rain and fire) affecting the reproductive activity of H. m

10. Expression and functional significance of VE-cadherin in aggressive human melanoma cells: Role in vasculogenic mimicry
We recently have introduced the term vasculogenic mimicry to describe the unique ability of aggressive melanoma tumor cells to form tubular structures and patterned networks in three-dimensional culture, which “mimics” embryonic vasculogenic networks formed by differentiating endothelial cells. In the current study, we address the biological significance

11. Cross-modal integration in a dart-poison frog
The mechanisms by which the brain binds together inputs from separate sensory modalities to effect a unified percept of events are poorly understood. This phenomenon was studied in males of the dart-poison frog Epipedobates femoralis. These animals physically and vigorously defend their territories against conspecific calling intruders. In prior field studie

12. Invasion of a rocky intertidal shore by the tunicate Pyura praeputialis in the Bay of Antofagasta, Chile
Invasion by marine nonindigenous species (NIS) is a spread phenomenon. The tunicate Pyura praeputialis shows pronounced disjoint geographical distribution: along thousands of kilometers in wave-swept headlands on the southeastern coast of Australia, from where it appears to have originated, and exclusively along 60–70 km inside the Bay of Antofagasta, Chil
