Water balance estimate of beans using a dynamic systems model based on crop coe...

The crop coefficient (Kc) is one of the most important parameters for studying the water balance, which aims to assess the relationship between growth and production dynamics and the management of water resources in irrigation systems. Thus, in this study, the effect of Kc variation on the water balance was evaluated throughout the bean crop cycle in Northeast Brazil, using a dynamic systems model. The effect o...

Policy forum: Shifting cultivation and agroforestry in the Amazon: Premises for...

Evidence shows that there is a close link between the intensification of shifting cultivation (SC) and the Amazon forest resilience. However, SC, to this day, is a widely implemented agricultural practice around the Amazon region due to its cultural, social, and economic relevance. In pristine indigenous communities, which have not experienced Western influence, SC will continue to be the main livelihood as par...

Biodiversity recovery of Neotropical secondary forests

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. S...

Phylogenetic structure is determined by patch size in rock outcrop vegetation o...

Ainda que os inselbergs ao redor do mundo sejam ecossistemas icônicos, pouco se sabe sobre os mecanismos subjacentes que estruturam suas comunidades vegetais, especialmente nas manchas de vegetação sobre afloramentos rochosos. Espera-se que as restrições ambientais causem agrupamento filogenético quando os nichos ecológicos são conservados dentro das linhagens evolutivas. Nós testamos se as manchas de vegetação...

Ecological drivers of tree diversity and ecosystem functioning during successio...

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; A floresta Amazônica vem sendo ameaçada pelas mudanças no uso da terra para a expansão da fronteira agrícola, provocando uma simplificação taxonômica e funcional, e em consequência gerando impactos negativos na relação da biodiversidade e funcionamento dos ecossistemas. Assim, o objetivo principal desta pesquisa foi avaliar os efeitos dos modeladores ...

Efecto de diferentes niveles dietéticos de harina de pescado sobre la producció...

El uso de la harina de pescado como suplemento nutricional en las dietas suministradas a codornices fue estudiado para identificar el efecto sobre la producción y calidad del huevo. Se analizaron 180 codornices bajo un diseño experimental completamente al azar, de tres bloques con seis tratamientos, tres repeticiones y 10 codornices por repetición. Se utilizaron dietas experimentales considerando diferentes niv...

Exploring the food and nutritional potential of three edibles amazonian arthropods

Ensuring food supply and availability, and consequently food safety, on a global scale represents one of the most important challenges of this century. The exploitation of local resources such as invertebrates has been extremely relevant to contribute to food security. However, most research has focused on evaluating the nutritional potential of insects, with very few studies approaching other invertebrate grou...
