Accurate environmental monitoring of aquatic ecosystems is often compromised by field-measurement biases introduced through human presence. Autonomous robotic platforms can mitigate these biases by enabling consistent, long-term data collection under a wide range of environmental conditions. We present the...
Euterpe precatoria Mart. is an increasingly important palm for subsistence and income generation in central and western Amazonia with growing demand for its fruit pulp, which is an alternative source of açaí juice for domestic and international markets. This study synthesizes current kn...
O objetivo do trabalho foi avaliar os efeitos do estresse pré-abate e durante o abate em tambaquis procedentes de piscicultura, pesando em média 1,100 ± 1,64 kg, que foram abatidos por asfixia com CO2 e por hipotermia em diferentes tempos amostrais (na despesca, após transport...
O presente estudo avaliou a eficácia da inoculação e coinoculação de rizóbios e bacilos na cultura do feijão-caupi (Vigna unguiculata cv. BRS Tumucumaque) no estado do Amazonas, visando potencializar a fixação biológica de nitrogênio e a solubilização de fósforo, promovendo maior eficiência&...
In order to monitor biodiversity changes in relation to climate change, different ecological niche models (ENMs) are employed. The selection of the most suitable model for a species may be constrained by various factors, such as data availability and resolution. The objective of th...
Amazon fig is an underexplored non-conventional food plant native to the Amazon region. The objective of this study was to determine its physicochemical properties, cytotoxicity, and chemical composition. The highest total phenolic content was observed in the hydroethanolic extract (709.5 mg ...
A pupunheira (Bactris gasipaes) é uma palmeira nativa da Amazônia cujos frutos são a principal forma de consumo pelos amazônidas e fonte de renda para extrativistas e agricultores familiares. Além da forma tradicional de consumo, a pupunheira éexplorada para a produção sustentável de&#x...
O açaizeiro (Euterpe oleracea, Arecaceae) é uma palmeira nativa da Amazônia tradicionalmente explorada no sistema extrativista e cujos frutos são destinados à produção de bebida conhecida como vinho de açaí. Em razão do consumo crescente o extrativismo não atende o aumento da demanda&#x...
The aim of this study, therefore, was to select PGPR from the rhizosphere of pepper plants grown in a Brazilian Amazonian savanna (Roraima state), using as selection criteria the QI obtained in the production of pepper seedlings, and to evaluate their ability to produce IAA,&#...
ABSTRACTThe objective of this study was to evaluate different concentrations of Aloysia triphylla essential oil (ATEO) on the productive performance of juvenile Apistogramma cacatuoides, as well as on liver morphology and intestinal villi morphometry. The experiment followed a completely randomized&#x...
