We studied the diet of a Chiasmocleis cordeiroi population in a fragment of the Atlantic Forest in the state of Bahia, Brazil. Frogs were collected at night after an explosive breeding event and were transferred to the lab where they were measured, weighed and had their stomach contents retrieved following a stomach flushing protocol. Individuals were later released back into the pond from which they had been collected. Stomach contents were measured and identified to the lowest possible taxonomic level. The most important prey category in the diet of C. cordeiroi was Hymenoptera (Formicidae), as has been already observed for other microhylids. The large number of prey items in the stomach and the low niche amplitude suggest that C. cordeiroi is a specialist using an active foraging strategy to detect its prey.

The orchid-bee faunas of ‘Parque Nacional do Monte Pascoal’, ‘Parque Nacional do Descobrimento’ and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the ‘Parque Nacional do Monte Pascoal’, the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at ‘Parque Nacional do Monte Pascoal’ and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

Kielmeyera ferruginosa, a new species of Calophyllaceae from the Atlantic Forest of southern Bahia, is here described and illustrated. The species is critically endangered and can be easily distinguished from other Kielmeyera species by the rusty coloration of the trunk and branches, orange-colored latex, and the occurrence in flooded areas. It differs from the other species of the section Prolifera by the leaves with secondary veins relatively more distant from each other and prominent on the abaxial surface. Diagnostic characters and the state of conservation of the new species are discussed, and an identification key for K. ferruginosa and related species from series Rupestres and Neglectae is provided.

Anurans are important prey for the American bullfrog Lithobates catesbeianus, but field assessments of its diet in the context of a local prey assemblage are lacking. We aimed to identify the frog species consumed by an invasive bullfrog population in subtropical South America, and to assess their relative importance among other types of prey. Characterization of the frog assemblage in the study area also allowed us to calculate the degree of electivity of the recorded anuran prey, in order to gain insight regarding bullfrog feeding preferences and to test if the bullfrog prey composition differed from a random sample of the assemblage. A total of 32.6% of the bullfrogs had at least one anuran in the stomach contents, and post-metamorphic anurans represented 49.1% of the relative prey importance for adult bullfrogs. Anurans were preyed on by all size classes, and constituted the volumetrically most important prey category in the diet of individuals heavier than 100 g. Cycloramphidae, Hylidae and Leiuperidae were positively selected, and Hypsiboas pulchellus and Physalaemus cuvieri were the species most often taken. We found a low occurrence of cannibalism, despite the high density of bullfrogs at the study site. Our results showed that the degree of electivity differed among bullfrog prey types, suggesting that some frog species may be preyed on in a higher proportion than their relative abundance in the assemblage. Testing the clues provided by this assemblage-level approach may lead to a better assessment of the interactions between bullfrogs and the native frog fauna.

A new species of Aparasphenodon is described from patches of arboreal restinga within the Atlantic Forest Biome, in a region known as Baixo Sul in southern Bahia, northeastern Brazil. Aparasphenodon arapapa sp. nov. is promptly diagnosed from other Aparasphenodon mainly by having small size (male snout-vent length 57.4–58.1 mm), loreal region flattened and wide, and canthus rostralis rounded and poorly elevated. The wide and flattened snout resembles that found in Triprion and Diaglena, and possibly is a parallelism (homoplasy) related to the phragmotic behavior of casque-headed tree frogs to their microhabitat usage. The decision to allocate the new species in the genus Aparasphenodon is discussed in detail, as the single morphological synapomorphy of the genus, the presence of a prenasal bone, is insufficient to morphologically relate the new species to Aparasphenodon, Triprion, or Diaglena.

An inventory of the amphibians of the Reserva Ecológica Michelin – REM in southern Bahia, Brazil is presented. Sixty-nine species were recorded during a ten-year sampling period. Amphibians were distributed in two orders (Gymnophiona and Anura), belonging to twelve families [Aromobatidae (1), Bufonidae (3), Centrolenidae (1), Craugastoridae (5), Eleutherodactylidae (3), Hemiphractidae (2), Hylidae (34), Phyllomedusidae (5) Leptodactylidae (7), Microhylidae (4), Odontophrynidae (3) and Caeciliidae (1)]. Fifty per cent of the reproductive modes known for Atlantic forest anurans were recorded. While no threatened species were found at REM, six species are classified as data deficient (DD) by the Brazilian Red List of threatened species and deserve additional attention.PhasmahylatimboandVitreoranaeurygnataare listed as endangered in Bahia according to the list of threatened species of the state. Despite a higher diversity of amphibians in the Atlantic forest having been reported for mountainous regions, our results revealed that amphibian richness for lowland forests is also high.

The stomach contents of 1261 striped marlins caught from 2007 to 2010 by the sport-fishing fleet of Cabo San Lucas, Baja California Sur, Mexico, were analysed, taking into account sea surface temperatures estimated using satellite images of the study area and the Oceanic Niño Index (ONI). The analysis allowed the identification of three anomalously cold periods during 2007, 2008 and 2010 and a warm period in 2009. The stomach content results showed 89 different prey items eaten during the study period. Of the specimens captured, 868 (69%) stomachs contained food items. The most important prey items were cephalopods (Dosidicus gigas and Argonauta spp.) and fish (Scomber japonicus, Selar crumenophthalmus and Sardinops caeruleus). Despite having a broad trophic spectrum, the striped marlin was classified as a specialist consumer, with Bi = 0.03. Based on the diet breadth value and the prey-specific index of relative importance (PSIRI), the jumbo squid, D. gigas, was the main prey species, coinciding with cold periods. On the other hand, the fishes S. caeruleus and S. japonicus showed the highest PSIRI values during the 2009 warm anomalies. Analysis of similarity showed the formation of four groups in relation to PSIRI values. According to a non-metric multidimensional scaling ordination, these groups were formed with a similarity of 30% and a stress of 0.17. These results demonstrate inter-annual variation in the diet as well as in the availability and abundance of prey items.

The orchid-bee fauna of ‘Reserva Biológica de Una’ (REBIO Una), one of the largest Atlantic Forest remnants in southern Bahia, eastern Brazil, was surveyed for the first time. Baits with sixteen different scents were used to attract males of orchid bees. Eight hundred and fifty-nine males belonging to 26 species were actively collected with insect nets during 60 hours in January and February, 2009, and January, 2010. Euglossa avicula Dressler, 1982 and Euglossa milenae Bembé, 2007 have been recorded for the first time in the state of Bahia. It was found that REBIO Una has one of the most diverse and rich orchid-bee faunas of the entire Atlantic Forest domain and holds some rare species, such as Euglossa cyanochloraMoure, 1996.

The Collared Anteater, Tamandua tetradactyla (Linnaeus, 1758), is a small mammal predator of ants. There are few studies describing which species are in fact consumed by them. This study was aimed to investigate the diversity and abundance of local species of ants preyed by the T. tetradactyla. Eight samples of stomach contents collected in the period from 2009 to 2014 were analyzed and identified at the lowest possible taxonomic level. We found 5,906 ants distributed in 16 species. The most abundant samples were number 2 and 4 with almost 2,000 individuals and the highest richness and abundance was Myrmicinae subfamily with eight species and 3,721 individuals. The ant richness found in this research demonstrates that the anteaters are generalists and opportunistic about their diet, not having a preference for a particular species, but rather for those insects that are available in their habitat.

Records of malformation in amphibians have significantly increased on a global scale. The main causes of malformations are linked to environmental contaminants, and records in preserved environments are uncommon. We reported malformations in three anuran species belonging to three families: Crossodactylustimbuhy (Hylodidae), Proceratophrysschirchi (Odontophrynidae) and Thoropamiliaris (Cycloramphidae). All records were found within the Reserva Biológica Augusto Ruschi, a well-preserved protected remnant of Atlantic rainforest located in the mountains of the state of Espírito Santo, southeastern Brazil. The malformations detected were hemimelia (long bone shortened) with ectrodactyly (digit absent) and brachydactyly (digit shortened) in C.timbuhy, microphtalmia (small eye) in P.schirchi and ectrodactyly in T.miliaris. Further studies are recommended to enable a better understanding about the incidence and causes of malformations within preserved areas.

A new species of the tree toad genus Dendrophryniscus is described from a rainforest habitat at Parque Nacional de Serra das Lontras, municipality of Arataca, southern Bahia, Brazil. Dendrophryniscus oreites sp. nov. is related to the Atlantic forest brevipollicatus group by hand morphology, skin texture, ventral coloration and bromelicolous habits. The new species differs from related species by having a larger size, warty skin, inner finger reduced with presence of a dark nuptial pad in males, and a yellowish coloration with discrete dorsal pattern. This discovery highlights the importance of southern Bahia in terms of conservation, and for our understanding of the evolution of the frog diversity within the Atlantic Rainforest.
