ABSTRACT Drepatelodes (Lepidoptera: Bombycoidea: Apatelodidae) is a genus of moths with very similar species, most of them described from the Amazon region, mainly from the Guiana Shield. Recent field samplings in the Fl...

ABSTRACT Interactions among organisms are important in ecosystem functioning and relevant for the management and conservation of species. Here we report the first record of a potential ant-hemiptera-plant mutualism on Lo...

ABSTRACT Essential oils derived from species of the genus Piper are widely recognized for their diverse chemical profiles and broad spectrum of biological properties, making them promising candidates for various applicat...

ABSTRACT Penicillium Link is a widely known genus of ascomycetes, with a worldwide distribution, mainly known for its use in the food industry and production of mycotoxins. Considering the importance of culture collectio...

ABSTRACT The points of susceptibility of seeds to deterioration are important factors, especially when stored in hot and humid tropical conditions. The seeds of andiroba (Carapa guianensis) are an important resource for ...

ABSTRACT This study evaluated the effects of organic diets formulated with Amazonian by-products on the productive parameters and health of juvenile tambaqui (Colossoma macropomum). Four experimental diets were tested: C...

ABSTRACT The palm species Astrocaryum chonta, popularly known as chonta or huicungo, was known only in periodically flooded forests of the Amazon region in Bolivia and Peru. However, reviewing specimens deposited in herb...

ABSTRACT White-sand forests are unique ecosystems with high levels of biological specificity. Despite their uniqueness, these ecosystems have significant knowledge gaps in Colombia regarding the associated vertebrate com...

ABSTRACT Tambaqui (Colossoma macropomum) skin represents a promising alternative for wound treatment due to its histological characteristics and mechanical properties. This study aimed to evaluate tambaqui skin preserved...

ABSTRACT The Amazon is one of the most biodiverse regions on the planet; however, from a botanical perspective, it remains underexplored and understudied. Here, we report distributional novelties from a botanical expedit...

ABSTRACT Pantepui is a biogeographic province in the Guiana Highlands, considered an archipelago of tabletop mountains (tepuis) with a unique and poorly-known biota. Here, we investigate the butterfly assemblage structur...

ABSTRACT Copaiba oleoresin is a natural product widely used in traditional Amazonian medicine in the treatment and cure of various ailments, having various biological activities such as anti-inflammatory, cicatrizant, an...

ABSTRACT On the southern edge of Brazilian Amazonia, within the Araguaia-Tocantins Basin, the Araguaia River and its main tributary, the Mortes River, are of high ecological, geopolitical and socioeconomic importance. Un...

ABSTRACT Lemnoideae is a yet little known taxon in Brazil in taxonomic and distributive terms, given the few records for the country, especially in the Amazon region. Here, we present the first record of Lemna minuta Kun...

ABSTRACT This paper reviews important processes that drive deforestation and its control in the Brazilian Amazon. Governmental programs decreased the rate of deforestation in the Amazon by 70% from 2004 to 2015. This lar...

ABSTRACT Knowledge regarding the reproductive biology of the Conopophaga genus remains limited, particularly concerning nesting behavior, parental care, and division of tasks between parents. In this study, we present th...

ABSTRACT Large catfishes form a diverse group with complex life histories, different habitat requirements and home range sizes, which may be related to several ecological aspects. Being among the main top predators in Am...

ABSTRACT Bryophytes play an important role as habitats for many organisms, especially invertebrates, however, few studies have focused on understanding the cryptic ecosystems associated with them. The use of molecular to...

ABSTRACT Fermented fish silage (FFS) produced from processing waste of the main fishery species in the Amazon could serve as an alternative with a circular economy approach. We determined the dietary effect of FFS as a r...

ABSTRACT Plant genotype is known to affect plant-invertebrate interactions. However, in megadiverse tropical habitats there has been relatively little exploration of the influence of the plant genotype on plant growth an...

ABSTRACT Endozoochory by lowland tapirs (Tapirus terrestris) is regarded as a key seed dispersal mechanism in tropical forests and thus potentially useful for ecological restoration. Although previous studies attested th...

ABSTRACT Aiming at improving accuracy and precision in the prediction of commercial stem volume, we compare species-specific and generic equations. Variables of 789 stems from 13 commercial tree species were measured, to...

ABSTRACT The study of lichens in Neotropical regions has uncovered a remarkable diversity, much of which remains largely unexplored. Within this context, several species of Sarcographa, including the common and widesprea...

ABSTRACT The Amazonian megadiversity remains understudied and underestimated due to the region’s vast size, environmental heterogeneity, and inaccessibility. With increasing threats to the biome, it is crucial to map c...
