13. First record of the invasive tapeworm, Schyzocotyle acheilognathi (Pseudophyllidea; Bothriocephalidae) in native freshwater fish, Brazil
ABSTRACT Schyzocotyle acheilognathi is a tapeworm cestode commonly found in native freshwater fishes from Asia. This cestode has low host specificity and for that reason it has been registered parasitizing more than 200 cultured and wild fish species, besides amphibians, reptiles and birds from different regions of the world. With a high pathogenic potential

15. Biological survey of a cloud forest in southwestern Mexico: plants, amphibians, reptiles, birds, and mammals
Abstract: Cloud forest ecosystems contain unique flora and fauna characterized by high levels of richness and endemism. However, this ecosystem is one of the most threatened because of land-use changes stemming from anthropogenic activities. Therefore, biological inventories are necessary to adequately assess the effects of land-use changes on species now an

16. The amphibians of the state of Rio de Janeiro, Brazil: an updated and commented list
Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and reva

17. Record of predation by two amphibians Rhinella major and Ctenophryne geayi by Erythrolamprus dorsocorallinus (Esqueda, Natera, La Marca & Ilija-Fistar, 2005) (Serpentes: Dipsadidae) in northwestern Brazil

18. Molecular evolution and functional divergence of alcohol dehydrogenases in animals, fungi and plants
Abstract Alcohol dehydrogenases belong to the large superfamily of medium-chain dehydrogenases/reductases, which occur throughout the biological world and are involved with many important metabolic routes. We considered the phylogeny of 190 ADH sequences of animals, fungi, and plants. Non-class III Caenorhabditis elegans ADHs were seen closely related to tet

19. The agricultural impact of pesticides on Physalaemus cuvieri tadpoles (Amphibia: Anura) ascertained by comet assay
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 inte

20. Looking for attitudes related to amphibian species decline: how are peer-reviewed publications of education activities compared to ecological research?
ABSTRACT Biodiversity decline has been the focus of discussions in the last decade, especially on the amphibian species decline. After a scientometric analysis using international databases, we found that the number of peer-reviewed articles considering education practices related to the theme increased along with the number of ecological researches. However

21. Dependencia térmica de la salamandra endémica de Colombia Bolitoglossa ramosi (Caudata, Plethodontidae)
ABSTRACT Environmental temperature is a determining factor in the physiological and behavioral processes of amphibians because they are ectotherms and consequently depend on external heat sources to achieve optimal body temperatures. The aim of this study was to determine the thermal dependence of the Colombian endemic salamander Bolitoglossa ramosi Brame &

22. Evolutionary analysis of apolipoprotein E by Maximum Likelihood and complex network methods
Abstract Apolipoprotein E (apo E) is a human glycoprotein with 299 amino acids, and it is a major component of very low density lipoproteins (VLDL) and a group of high-density lipoproteins (HDL). Phylogenetic studies are important to clarify how various apo E proteins are related in groups of organisms and whether they evolved from a common ancestor. Here, w

23. Genetic analysis reveals candidate species in the Scinax catharinae clade (Amphibia: Anura) from Central Brazil
Abstract Scinax (Anura: Hylidae) is a species-rich genus of amphibians (113 spp.), divided into five species groups by morphological features. Cladistic analyses however revealed only two monophyletic clades in these groups: Scinax catharinae and Scinax ruber. Most species from the S. catharinae clade are found in Atlantic rainforest, except for Scinax canas

24. Cinerascetins, New Peptides from Hypsiboas cinerascens: MALDI LIFT-TOF-MS/MS de novo Sequence and Imaging Analysis
The continuous search for antimicrobial candidates pushes the pursuit of compounds in the most diverse organisms. Amphibians are known as a prolific source of antibacterial peptides. Based on the rich biodiversity of the Amazon region the unexplored green-tree frog (Hypsiboas cinerascens) was studied for its skin secretion peptide content. Chromatographic se
