    This identifies insects visiting and/or pollinating the flowers of the study "African Oil Palm" Elaeis guineensis Jacq. and the "Brazilian Oil Palm" Elaeis oleifera (H.B.K.) Cortés. Insects were collected at different times of day at different locations, when the male inflorescences were at full anthesis. A total of 159 individual insects were collected including, among others, Meliponid bees: Trigona spp. (on African and Brazilian Oil Palms), Apis mellifera adansonii and Partamona sp. (on African Oil Palm). Also observed were a considerable number of insects in genus Elaeidobius (family Curculionidae) flying about the inflorescence, indicating that they also play a role in the pollination of both palm species. Beetle larvae in the family Lycidae were also noted on the plant inflorescences.Este trabalho tem como objetivo a identificação dos insetos visitantes e polinizadores das flores do "dendê" Elaeis guineensis Jacq., e do "caiaué" Elaeis oleifera (H.B.K) Cortés, atráves de coletas em locais e horários diferentes, quando as inflorescências masculinas das plantas encontravam-se em plena antese. Um total de 159 insetos foram observados tendo sido constatado dentre os diversos tipos de visitantes, os meliponídeosTrigona sp. dendê" e "caiaué"), Apis mellifera adansonni e Partamona sp. dendê"). Constatou-se ainda a presença de uma quantidade razoável de insetos da família Curculionidae do gênero Elaeidobius, que voavam em torno das inflorescências, sendo evidente a sua participação na polinização das espécies estudadas. Além disso, verificou-se a presença de larvas de um coléoptero da família lycidae, junto as inflorescências das plantas

    Elaeis oleifera (Kunth) Cort√©s (American oil palm) has advantageous characteristics for hibridization with E. guineensis which vary among populations. In order to contribute to population discrimination, we studied pollen morphology of ten Amazonian populations (Acajatuba, Amatari, Autazes, BR-174, Careiro, Manicor√©, Mau√©s, Moura, Novo Aripuan√£, Tef√©). The acetolysis method was used to eliminate cell contents and enable observations on pollen size, shape, aperture and exine surface. Pollen grains from the Novo Aripuan√£ population had the largest mean grain size (49 őľm) and populations from Amatari, BR-174 and Moura the smallest (42.5 to 44 őľm). Pollen is elliptic or piriform, aperture type is monocolpate and exine surface is microreticulate. Pollen grains with morphological abnormalities were also found. Pollen morphology discriminated three groups of Amazonian populations and offers an important tool for population discrimination, especially when associated with other analyses.Elaeis oleifera (Kunth) Cort√©s - Arecaceae (caiau√©) apresenta caracter√≠sticas vantajosas para a hibrida√ß√£o com o dend√™ E. guineensis que variam entre popula√ß√Ķes. Com o objetivo de contribuir para a discrimina√ß√£o de popula√ß√Ķes amaz√īnicas, caracterizou-se a morfologia do p√≥len de dez popula√ß√Ķes de caiau√© (Acajatuba, Amatari, Autazes, BR-174, Careiro, Manicor√©, Mau√©s, Moura, Novo Aripuan√£ e Tef√©). Utilizou-se o m√©todo da acet√≥lise para elimina√ß√£o do conte√ļdo celular e observou-se o tamanho, forma, abertura e superf√≠cie dos gr√£os de p√≥len. A popula√ß√£o Novo Aripuan√£ apresentou maior tamanho m√©dio dos gr√£os de p√≥len (49,0 őľm) e as popula√ß√Ķes Amatari, BR-174 e Moura os menores (42,5 a 44,0 őľm). Os gr√£os de p√≥len s√£o el√≠pticos ou piriformes, com abertura monocolpada e superf√≠cie microrreticulada. Observou-se, tamb√©m, anormalidades morfol√≥gicas em alguns gr√£os. A morfologia pol√≠nica separou as popula√ß√Ķes amaz√īnicas em tr√™s grupos e, quando associada a outras an√°lises (isoenzimas e DNA), pode representar uma ferramenta importante na discrimina√ß√£o de popula√ß√Ķes

    Natural resources from the palm trees Euterpe oleracea, Astrocaryum aculeatum, Mauritia flexuosa, Bactris gasipaes, Oenocarpus bacaba and Attalea maripa potentially favor the use of biodiversity and are economically formidable in the national market due to the total utilization of its products and sub-products. The objective of this research was to conduct a survey, based on the search for patents and scientific papers, in order to identify the potential for the bio-economy of native palm trees in the Brazilian Amazon region. For this, exploratory documentary research with a quantitative approach was carried out, and analyzed the patent documents filed with the databases of the National Institute of Industrial Property of Brazil; Latin American Patent Bank; United States Patent and Trademark Office; European Patent Office and World Intellectual Property Organization. For scientific prospection, a bibliographic search was carried out regarding publications of scientific papers from Elsevier research platforms, including Scopus, Science Direct, Springer link, Scielo and Capes Journal databases. The results of the prospecting were compiled in data networks and graphs. From a scientific point of view, the species Euterpe oleracea and Astrocaryum aculeatum stand out as sources of potentially bio-economic biological resources, and present an extensive number of publications regarding the chemical activities of the fruits. The United States Patent and Trademark Office has the highest number of patent filings, for the species Euterpe oleracea. This indicates that Brazil leads as the main depositor country, due to the high wealth of these species. Among the patent filings surveyed, most were classified by the code IPC A61K, which related to obtaining tablets containing ethanolic extract (standardized) from the fruits and its application as an antioxidant. In the light of this analysis, this study made it possible to present an overview of the technological and scientific potential of the palm species, significantly revealing their potential to meet human needs in the areas of food and health, which can be explored by the industry with a perspective for generation of new technologies.Os recursos naturais provindos das palmeiras Euterpe oleracea, Astrocaryum aculeatum, Mauritia flexuosa, Bactris gasipaes, Oenocarpus bacaba e Attalea maripa potencialmente favorecem o aproveitamento da biodiversidade e s√£o economicamente vi√°veis ao mercado nacional, em virtude do aproveitamento integral de seus produtos e subprodutos. O objetivo desta pesquisa foi realizar uma prospec√ß√£o baseada na busca de patentes e produ√ß√£o cient√≠fica de modo a identificar as potencialidades para a bioeconomia das palmeiras nativas da regi√£o amaz√īnica brasileira.

    Introduction: Activated carbon is a porous substance of organic material, usually woody and fibrous material. The raw materials used to obtain charcoal are almost exclusively of vegetable origin, possessing high carbon power. The study consists of considering the use of Brazil nut hedgehogs as a raw material in the production of activated carbon. Originality/Relevance: In this study, the results of the analysis of the economic viability of the use of activated carbon produced with residues of Brazil nuts from the Amazon region, aims to generate economic benefits and reduce possible environmental damage.¬† Methodology: The study was developed from a simulation of the implementation of a Manufacturing Unit at Aruan√£ Farm, a case study site, near of 215 km from the city of Manaus-AM, based on its data and internet sources.¬†¬†¬† Results: The financial¬† indexes,¬† resulting from the¬† simulations of three scenarios of activated carbon production¬†¬† with residues obtained from the¬† hedgehog, indicate that it¬† would be unfeasible to¬† implement it to use only¬† the¬† waste from¬†¬† hedgehogs from¬† the current productive chestnut trees on¬†¬† the Farm, but¬† that would be feasible¬† from 540,890¬† productive¬†¬† chestnut trees on the Farm and from other sources. Conclusion: It is economically feasible to implement a Manufacturing Unit on the Farm with a minimum possible size and¬† to keep it producing the whole¬† year it would be necessary to seek the supply of hedgehogs from other sources and in quantity well above the production capacity of theFarm.Introdu√ß√£o: O carv√£o ativado √© uma subst√Ęncia porosa de material org√Ęnico, geralmente material lenhoso e fibroso. As mat√©rias-primas usadas para obten√ß√£o do carv√£o s√£o quase exclusivamente de origem vegetal, possuindo alto poder de carbono. O estudo consiste em pesquisar o uso do ouri√ßo de castanha-do-brasil como mat√©ria-prima na produ√ß√£o de carv√£o ativado. Originalidade/Relev√Ęncia: Neste estudo, os resultados da an√°lise da viabilidade econ√īmica do uso do carv√£o ativado produzido com res√≠duos da castanha-do-brasil da regi√£o Amaz√īnica, visa gerar benef√≠cios econ√īmicos e reduzir poss√≠veis danos ambientais. Metodologia: O estudo foi desenvolvido a partir de simula√ß√£o da implanta√ß√£o de uma Unidade Fabril na Fazenda Aruan√£, local de estudo de caso, acerca de 215 km da cidade Manaus-AM, com base em seus dados e fontes da internet. Resultados: Os √≠ndices financeiros, resultantes das simula√ß√Ķes de tr√™s cen√°rios de produ√ß√£o de carv√£o ativado com res√≠duos obtidos do ouri√ßo, indicam que seria invi√°vel sua implanta√ß√£o para utilizar apenas os res√≠duos dos ouri√ßos das atuais √°rvores de castanheiras produtivas na Fazenda, mas que seria vi√°vel a partir de 540.890 castanheiras produtivas na Fazenda e de outras fontes. Conclus√£o: √Č vi√°vel economicamente a implanta√ß√£o de uma Unidade Fabril na Fazenda com um tamanho m√≠nimo poss√≠vel e para mant√™-la produzindo o ano inteiro seria necess√°rio buscar o suprimento de ouri√ßos de outras fontes e em quantidade bem superior √† capacidade de produ√ß√£o da Fazenda

    Palmas de comunidades ribere√Īas como recurso sustentable en la amazon√≠a brasile√Īa

    In the Amazon, approximately 30% of the population is agglomerated in small villages or isolated areas. One of the most serious problems is the lack of electricity, where reduced supply and frequent rationing reduce life quality and prevent the instalation of industries that could raise the value of renewable regional products. Consequently, the pursuit of better socioeconomic conditions promote the quick depletion of natural resources, which invariably results in the accelerated destruction of local ecosystems. Oil palms, that are mainly used for basic nutrition of local populations, could also form the basis for models of self-sustained technological and industrial development. A quantitative survey of native species of oil palms offers an alternative for sustained development based on a technological and industrial model because this resource occurs in populated areas in the Amazon, which facilitates retaining the people in the field, preventing the depletion of natural ecosystems. This study presents the activities that were used to identify the potential of biomass of Euterpe precatoria Mart and other oil palms available in riverside communities in the state of Amazonas (Brazil). These activities are associated with the possibilities of using palm species for sustainable development of energy generation. It was possible to identify the conditions for a sustainable supply of biomass as an alternative energy source which contributes to the Energy Universalization Program in the Brazilian Amazon. ¬© Facultad de Ciencias Biońļgicas UNMSM

    O objetivo geral do artigo √© identificar as ocorr√™ncias e demandas do servi√ßo de prote√ß√£o ambiental das Unidades de Conserva√ß√£o no munic√≠pio de Manaus e propor melhorias na sua atua√ß√£o. Os Objetivos Espec√≠ficos s√£o: Levantar aspectos legais e conceituas da Unidade de Conserva√ß√£o brasileira; Identificar ocorr√™ncias atendidas pelos √≥rg√£os da Seguran√ßa P√ļblica dentro e fora das Unidades de Conserva√ß√£o no munic√≠pio de Manaus; e Descrever e propor instrumentos t√©cnicos e legais (administrativos e normativos) na forma√ß√£o de um corpo especializado na seara ambiental que se ad√©que e possibilite o atendimento das demandas oriundas das ocorr√™ncias registradas. Para o alcance do objetivo proposto, a metodologia aplicada foi considerada explorat√≥ria, com uma abordagem descritiva e quali-quantitativa. Al√©m disso, foi necess√°rio realizar uma busca no Centro Integrado de Opera√ß√Ķes de Seguran√ßa (CIOPS) e no Cart√≥rio Delegacia Especializada em Crimes Contra o Meio Ambiente (DEMA). Conclui-se que a Guarda Municipal tem a miss√£o de proteger o patrim√īnio ecol√≥gico, atuando no espa√ßo p√ļblico, parques, monumentos hist√≥ricos, com a√ß√Ķes e pr√°ticas educativas voltadas a conserva√ß√£o do meio ambiente, mas os resultados mostram que a forma de atua√ß√£o dos Guardas Municipais √© insatisfat√≥ria, devido a uma falta de entendimento por parte dos agentes sobre suas atribui√ß√Ķes para atuar na UC. Recomenda-se que os gestores equipem suas corpora√ß√Ķes para que seja poss√≠vel exercer a atividade fazendo com que essa categoria seja um instrumento de sua pol√≠tica Ambiental Municipal

    The pollen grains collected by Melipona seminigra merrillae, Melipona compressipes manaosensis, Melipona seminigra seminigra, Frieseomelitta sp. and Scaptotrigona sp. were obtained directly from the corbiculae of the worker bees during one year. Identification of the pollen grains showed that Scaptotrigona sp. was the most generalist bee, followed by Frieseomelitta sp., which together collected more pollen taxa than the three species of Melipona. Pollen from three plant species: - Miconia myrianthera, Myrcia amazonica e Tapirira guianensis -were collected by this five bee species. Regarding pollen morphology, no significant correlations were found that could indicate a preference for certain pollen grain forms, external structures or sizes of grains. All five meliponids collected pollen of several forms and sizes. It is indicative that the bees collected pollen in accordance to protoplasmic nutrients. Biochemical analyses of some pollen types carried on the corbiculae of the bees showed a high concentration of total soluble sugars, reductive sugars and starch.Durante um ano, o p√≥len transportado por Melipona compressipes manaosensis, Melipona seminigra merrillae, Melipona seminigra seminigra, Frieseomelitta sp. e Scaptotrigona sp. foi coletado diretamente das corb√≠culas das oper√°rias. Feita a identifica√ß√£o dos gr√£os de p√≥len constatou-se que a abelha mais generalista foi Scaptotrigona sp., seguida de Frieseomelitta sp., as quais juntas coletaram mais tipos pol√≠nicos que as tr√™s esp√©cies de meliponas. Duas esp√©cies de plantasMiconia myrianthera e Myrcia amazonica, tiveram seu p√≥len coletado pelas cinco esp√©cies de melipon√≠neos durante o ano todo. Quanto √† morfologia do p√≥len, n√£o houve correla√ß√£o significativa que comprovasse que as abelhas coletassem o p√≥len de acordo com a forma, ornamenta√ß√£o e o tamanho dos gr√£os. As cinco esp√©cies de melipon√≠neos coletaram p√≥len de diversas formas e tamanhos. Tudo indica que as abelhas coletam o p√≥len de acordo com os nutrientes contidos no seu protoplasma. An√°lises bioqu√≠micas de alguns tipos pol√≠nicos encontrados nas corb√≠culas das abelhas apresentaram alto teor de a√ß√ļcares sol√ļveis totais, a√ß√ļcares redutores e amido

    Bioeconomic Potential of Sustainability Indicators in a Ceramic Production Center in the Western Amazon

    Get PDF
    The use of Amazonian biodiversity has great potential to produce bioproducts in diverse production chains and segments of industry. The combination of public policies with biotechnological development represents an important indicator for the implementation of sustainable production chains that adhere to the Sustainable Development Objectives (SDO). The ceramic industries in the Amazon region represent activities that promote local economic development through the use of biological resources that can be transformed into bioproducts that are considered a reference for sustainable production in world markets. The operations of these industries have great potential to incorporate technologies that can be used for fabrication of ceramic products on a biological base that is compatible with bioeconomic guidelines. The principle of a bioeconomy is centered on the possibility of transformation of natural resources into bioproducts that aggregate technologies and contribute to increase incomes and reduce environmental impacts. In this way, the integration of different fields of science should be stimulated to incorporate new technologies that favor business models that comply with the premises of sustainability
