Critical thermal maximum (CTmax) is often used as an index of upper thermal tolerance in fishes; however, recent studies have shown that some fishes exhibit agitation or avoidance behavior well before the CTmax is reached. In this study, we quantified behavioral changes during CTmax trials in two Amazonian cichlids, Apistogramma agassizii and Meson...

Length-weight relationships were estimated for 47 fish species for Auati-Paraná channel in Central Brazilian Amazonia. Sampling was carried quarterly during 2013 year, using seine net (3 mm stretch mesh size) for the collections in floating vegetation and hand nets in litter of the littoral zone. This study provides new information on the length-we...

The present study reviews the records of occurrences of fish species found in the Mamirauá Sustainable Development Reserve (MSDR). The reserve is located in a large section of the middle Solimões River basin, in its interflow with Japurá River. For the elaboration of the list of fish species occurring in Mamirauá Reserve, we used a database of diff...

To the best of our knowledge, this is the first record of T. atlantica visiting and feeding on nectar and supposedly or actually pollinating flowers of M. carthaginensis.

Copiphora longicauda Serville, 1831 is a species of Amazonian katydid described for French Guiana and with records for Colombia, Peru and Suriname. In this contribution, the record of this species is made for the first time to Brazil, with inclusion of natural history and a map with the geographical records.

At 1300 h on 14 March 2017 an adult D. dendrophis (ca. 80 cm total length) was observed preying on an adult Chiasmocleis shudikarensis (Anura: Microhylidae; ca. 2.5 cm body length). This observation extends the diet breadth of D. dendrophis to fossorial anurans.

We found two male R. merianae in amplexus with two female R. marina. Although cases of interspecific amplexus in Rhinella are common, in this note, we report interspecific amplexus between R. merianae and R. marina for the first time.

We found two male R. merianae in amplexus with two female R. marina (Fig. 1A, B). Although cases of interspecific amplexus in Rhinella are common, in this note, we report interspecific amplexus between R. merianae and R. marina for the first time.

Paraxiphidium is a genus of flashy Neotropical katydids belonging to Conocephalini. Paraxiphidium iriodes sp. nov. is described from the Brazilian Amazon region. This is the first record of the genus for Brazil. The description of stridulatory file, male internal genitalia and data on natural history is provided. A key is included to the species of...

Aim The objective of this work is to record the occurrence of Apistogrammoides pucallpaensis in Brazilian territory, since so far its distribution is restricted to Peru and Colombia. Methods The collections were carried out in the year of 2013, during the research of ichthyofauna of the region of Auati-Paraná, located in the Mamirauá Reserve in th...

A Reserva de Desenvolvimento Sustentável Mamirauá (RDSM), possui ambientes tanto de várzea quanto de terra firme os quais são influenciados pela força do pulso de inundação, estes ecossistemas estão entre os mais importantes sistemas aquáticos amazônicos em termos de biodiversidade. A espécie em estudo Apistogrammoides pucallpaensis pertencente à f...

Meconematinae comprise small predatory katydids. There are currently seven genera and 58 species recorded for the Neotropical region. Two new genera of Phlugidini are described from the Amazon region, Arboraptor gen. nov., type species Arboraptor viridis sp. nov., and Tyrannoraptor gen. nov., type species Tyrannoraptor arboreus (Nickle, 2003) n. co...

Osteglossidae is a family characterized by the bone and rough tongue, has the body flattened laterally and the presence of barbels at the extremity of the chin. Their representatives are considered generalist predators, who jump out of water to capture food. O. bicirrhosum presents commercial interest, appreciated as food and ornamental species. Th...

Apistogramma agassizii is a dwarf cichlid species endemic of the Amazon basin, about which there is little biological and ecological information in their natural habitat, despite their ornamental importance. This study evaluated the populacional structure A. agassizii at Amana Sustainable Development Reserve, Middle Solimões basin, Amazonas, Brazil...

The reproductive parameters are among the most important life history aspects of fishes influenced by environmental variation. During recent years, the main life history strategies of Amazonian fish species were defined mostly by a set of reproductive parameters. In the present work, we sought to describe important life history parameters, in parti...

This record documents a novel prey species for D. corais and corroborates the idea that D. corais is a diurnal snake that probably captures nocturnal prey when they are sheltered or resting (Bernarde and Abe, op. cit.).

The description of the female of Phlugis gracila and the addition of new characters to the original male description are provided. The description of the male stridulatory file and genitalic morphology is noted for the first time. This is the first record for the species in Brazil (Amazonas) and its natural history is noted.

Phlugiola Karny, 1907 is a genus of small predatory katydids with six included species distributed in Brazil, Bolivia, Colombia, Peru and Suriname. In this paper two new Brazilian species are described, Phlugiola longipedes sp. nov. (type locality: Amazonas, Tefé) and Phlugiola igarape sp. nov., (type locality: Acre, Bujari) both from tropical rain...

A educação e percepção ambiental despontam como armas na defesa do meio natural e ajuda a reaproximar o homem da natureza, garantindo um futuro com mais qualidade de vida para todos, já que desperta uma maior responsabilidade e respeito dos indivíduos em relação ao ambiente em que vivem. Este trabalho tem como objetivo avaliar o nível de percepção...
