Resumo A restauração florestal é baseada nas relações planta-solo e espécies vegetais com potencial econômico, mas aquelas entre insetos e outros artópodes são, também, importantes para esse processo. O objetivo foi avaliar as relações entre formigas, fitófagos Hemiptera e predadores e a distribuição (agregada, aleatória ou regular) de artrópodes, por 24 meses, em mudas de Acacia auriculiformis utilizadas na recuperação de áreas degradadas. Os artrópodes foram amostrados, armazenados e identificados e suas relações e padrões de distribuição calculados com o software BioDiversity-Pro. Os números de formigas cuidadoras se correlacionaram, positivamente, com os dos Hemiptera fitófagos Aethalion reticulatum, Brachymyrmex sp. e Cephalotes e Aleyrodidae. Insetos cuidadores de Hemiptera foram, negativamente, correlacionados com predadores Sternorrhyncha em plantas de A. auriculiformis. A distribuição dos artrópodes foi agregada, exceto Teudis sp. e Cephalocoema sp., com padrão aleatório. Aethalion reticulatum, Stereoma anchoralis e Tetragonisca angustula foram os herbívoros e Brachymyrmex sp. e Dolichopodidae os predadores mais abundantes. As relações entre os artrópodes estudados em A. auriculiformis indicam que esta planta, mesmo introduzida, é adequada para programas de recuperação de áreas degradadas no cerrado.

Abstract Forest restoration is mainly based on plant-soil relationships and plant species with economic potential, but those between insects and other arthropods are also important to this reestablishment. The objective was to evaluate, during 24 months, the relationships between tending ants, Hemiptera phytophagous, predators and their distribution pattern (aggregated, random or uniform). The arthropods were sampled, stored and identified and their relationships and distribution patterns calculated with the BioDiversity-Pro software. The number of tending ants and phytophagous Hemiptera, Brachymyrmex sp. and Aethalion reticulatum, Cephalotes and Aleyrodidae were positively correlated. Tending ants were negatively correlated with Sternorrhyncha predators on A. auriculiformis saplings. The distribution of arthropods was aggregated, except for Teudis sp. and Cephalocoema sp., with a random pattern. The herbivores Stereoma anchoralis, Aethalion reticulatum and Tetragonisca angustula and the predators Brachymyrmex sp. and Dolichopodidae were the most abundant arthropods. The relationships between the arthropods studied on A. auriculiformis indicate that this plant, even introduced, is suitable for programs to recover degraded areas in the savannah.

ABSTRACT Purpose: To determine the relationship of ocular surface disease, the number of glaucoma medications prescribed and its influence on treatment adherence. Methods: In this cross-sectional study, demographic data of patients with glaucoma were collected, and patients completed the ocular surface disease index questionnaire and the glaucoma treatment compliance assessment tool. Ocular surface parameters were assessed by “Keratograph 5M.” Patients were stratified into two groups according to the amount of prescribed ocular hypotensive eye drops (Group 1, one or two classes of medications; Group 2, three or four classes) Results: In total, 27 eyes of 27 patients with glaucoma were included: 17 using 1 or 2 topical medications (Group 1) and 10 eyes using 3 or 4 classes (Group 2). For the Keratograph assessment, patients using ≥3 medications had significantly smaller tear meniscus height (0.27 ± 0.10 vs. 0.43 ± 0.22; p=0.037). The analysis of Ocular Surface Disease Index questionnaire showed higher scores among the groups using more hypotensive eye drops (18.67 ± 13.53 vs. 38.82 ± 19.72; p=0.004). Regarding the glaucoma treatment compliance assessment tool, Group 2 had worse scores in components of forgetfulness (p=0.027) and barriers due to lack of drops (p=0.031). Conclusion: Patients with glaucoma using more hypotensive eye drops had worse tear meniscus height and ocular surface disease index scores than those using fewer topical medications. Patients using three or four drug classes had worse predictors of glaucoma adherence. Despite worse ocular surface disease results, no significant difference in self-reported side effects was found.

RESUMO Objetivo: Determinar a relação entre doença da superfície ocular (OSD), número de medicamentos prescritos para o glaucoma, e como isso influencia na adesão ao tratamento. Métodos: Neste estudo transversal, pacientes com glaucoma foram submetidos à coleta de dados demográficos, preenchimento do questionário Ocular Surface Disease Index e do Glaucoma Treatment Compliance Assessment Tool. Os parâmetros da superfície ocular foram avaliados pelo “Keratograph 5M”. Indivíduos foram estratificados em 2 grupos de acordo com a quantidade de colírios hipotensores oculares prescritos (Grupo 1: uma ou duas classes de medicamentos; Grupo 2: três ou quatro classes). Resultados: No total, 27 olhos de 27 pacientes com glaucoma foram incluídos: 17 usando 1 ou 2 medicamentos tópicos (Grupo 1) e 10 olhos usando 3 ou 4 classes (Grupo 2). Na avaliação do Keratograph, os pacientes em uso de 3 ou mais medicamentos apresentaram altura do menisco lacrimal significativamente menor (0,27 ± 0,10 vs. 0,43 ± 0,22; p=0,037). Análise do questionário OSDI mostrou escores mais altos entre o grupo que usou mais colírios hipotensores (18,67 ± 13,53 vs. 38,82 ± 19,72; p=0,004). Em relação ao Glaucoma Treatment Compliance Assessment Tool, o Grupo 2 apresentou piores escores nos componentes de esquecimento (p=0,027) e barreiras por falta de colírios (p=0,031). Conclusão: O estudo demonstrou que pacientes com glaucoma usando mais colírios hipotensivos apresentaram piores escores de altura do menisco lacrimal e Ocular Surface Disease Index, em comparação com aqueles que usaram menos medicamentos tópicos. Pacientes em uso de 3 ou 4 classes de colírios tiveram piores preditores de adesão ao glaucoma. Apesar dos piores resultados de doença da superfície ocular, não houve diferença significativa nos efeitos colaterais relatados.

ABSTRACT: Lettuce and arugula are the most cultivated leafy vegetables in hydroponic systems in the world, and the little information about Azospirillum brasilense effects in research in this system makes it necessary to verify the best method of inoculation of these bacteria. Therefore, this study aimed to verify the beneficial effects of inoculation methods of A. brasilense on plant growth and nutrition of lettuce and arugula grown in the hydroponic system. The study was conducted in a greenhouse with 30% shading. A randomized block design with five replicates in a 4 × 2 factorial scheme was used. Four A. brasilense inoculation methods (non-inoculated, foliar application, nutrient solution, and nutrient solution + foliar application) and two leafy vegetable species - arugula and lettuce - were evaluated. All inoculation methods improved plant height, shoot fresh and dry mass, root fresh and dry mass, fresh leaf yield, leaf chlorophyll index, accumulation of nitrogen, potassium, calcium, sulfur, phosphorus, iron, manganese, and copper and reduced nitrate accumulation in shoot and root of arugula and lettuce. Inoculation via nutrient solution + foliar application of A. brasilense is the most suitable for hydroponic arugula cultivation because it provides greater fresh leaf yield. All inoculation methods increased leaf yield in hydroponic lettuce. Hydroponic arugula and lettuce plants showed greater accumulation of nutrients and plant growth with less nitrate accumulation in the shoot under inoculation with A. brasilense.

RESUMO A alface e a rúcula são as hortaliças folhosas mais cultivadas em sistemas hidropônicos no mundo, e as poucas informações sobre os efeitos do Azospirillum brasilense em pesquisas neste sistema torna-se necessário verificar o melhor método de inoculação dessas bactérias. Portanto, o objetivo deste estudo foi verificar os efeitos benéficos de métodos de inoculação de A. brasilense em alface e rúcula no crescimento e nutrição das plantas em sistema hidropônico. O estudo foi conduzido em casa de vegetação com 30% de sombreamento. Foi usado o delineamento em blocos ao acaso com 5 repetições em esquema fatorial 4 × 2, com quatro métodos de inoculação de A. brasilense (não inoculado, foliar, solução nutritiva e solução nutritiva + inoculação foliar) e o segundo fator foi a aplicação em rúcula e alface. Todos os métodos de inoculação melhoraram a altura da planta, massa fresca e seca da parte aérea, massa fresca e seca da raiz, rendimento da planta, índice de clorofila foliar, acúmulo de nitrogênio, potássio, cálcio, enxofre, fósforo, ferro, manganês, cobre e redução do acúmulo de nitrato na parte aérea e raízes de rúcula e alface. A inoculação via solução nutriente + inoculação foliar de A. brasilense é a mais indicada para o cultivo hidropônico de rúcula, pois proporciona maior rendimento de folhas, e todos os métodos de inoculação foram capazes de aumentar o rendimento de folhas em alface hidropônica. Plantas hidropônicas de rúcula e alface apresentaram maior acúmulo de nutrientes e crescimento das plantas com menor acúmulo de nitrato na parte aérea sob inoculação com A. brasilense.

ABSTRACT The objective of this study was to evaluate the effects of different combinations of nitrogen and potassium fertilization on gas exchange and chlorophyll a fluorescence in seedlings of guava cv. Paluma irrigated with water of different salinity levels. The experiment was set up in a randomized block design and analyzed in 5 × 4 factorial scheme, with four replicates. The treatments were composed of the combination of the factor electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), with the factor combinations (C) formed from recommended doses of nitrogen (N) and potassium (K2O), 70% N + 50% K2O, 100% N + 75% K2O, 130% N + 100% K2O, and 160% N + 125% K2O. The fertilization combination 130% N + 100% K2O mitigated the effects of salt stress up to mean ECw of 1.3 dS m-1, resulting in increments in CO2 assimilation rate, transpiration, instantaneous carboxylation efficiency, and electron transport rate. For maximum quantum efficiency of photosystem II, only treatment irrigated with ECw 3.5 dS m-1 under the combination 160% N + 125% K2O showed damage to the photosynthetic apparatus.

RESUMO Objetivou-se com o presente estudo avaliar os efeitos de diferentes combinações de adubação nitrogenada e potássica sobre as trocas gasosas e fluorescência da clorofila a em mudas de goiabeira cv. Paluma irrigadas com águas de distintas salinidades. O experimento foi instalado em delineamento em blocos casualizados e analisados no esquema fatorial 5 × 4, com quatro repetições. Os tratamentos foram compostos a partir da combinação do fator condutividade elétrica da água de irrigação - CEa (0,3; 1,1; 1,9; 2,7 e 3,5 dS m-1) com o fator combinações (C) formada a partir de doses recomendadas de nitrogênio (N) e potássio (K2O): 70% N + 50% K2O; 100% N + 75% K2O; 130% N + 100% K2O e 160% N + 125% K2O. A combinação de adubação 130% N + 100% K2O mitigou o estresse salino até a CEa média de 1,3 dS m-1, resultando em aumento na taxa de assimilação de CO2, transpiração, eficiência instantânea de carboxilação e taxa de transporte de elétrons. Para a máxima eficiência quântica do fotossistema II, apenas os tratamentos irrigados com CEa 3,5 dS m-1 e combinação 160% N + 125% K2O apresentaram danos no aparelho fotossintético.

This work describes a green synthesis, the characterization, and biological evaluation of silver nanoparticles (AgNPs). The AgNPs suspension was synthesized using aqueous leaf extract of Eucalyptus grandis, which presented a characteristic band at 407 nm in the UV-Vis spectrum. The AgNPs presented a spherical shape and size of 9.7 ± 0.3 nm. The nanoparticles were stable over a month, indicating that E. grandis’ extract is suitable for their preparation and stabilization. The X-ray analysis showed that the crystallinity of AgNPs corresponded to the centered face phase of silver. The antibacterial and leishmanicidal activities of AgNPs were evaluated. The AgNPs presented antibacterial activity on the Gram-negative bacteria Escherichia coli at 53.9 µg mL-1. The leishmanicidal activity evaluation against promastigote forms of Leishmania infantum, Leishmania amazonensis, and Leishmania braziliensis showed that the biological response is dependent on the volume of AgNP suspension. It was demonstrated that L. infantum was more sensitive to the nanoparticle’s treatment than L. amazonensis and L. braziliensis. The treatment of L infantum promastigotes with 150 µL of AgNP suspension reduced parasite growth by 67.9%, a result which was similar to the treatment with 1 (66.7%) or 2 µL (70.6%) of amphotericin B used as a positive control.

Abstract Congenital anomalies (CA) are a relevant problem for global public health, affecting about 3% to 6% of newborns worldwide. In Brazil, these are the second main cause of infant mortality. Thus, extensive studies are needed to demonstrate the impact of these anomalies on births and deaths. The present study describes the temporal trends of prevalence and infant mortality due to CA among live births in Brazil and regions, from 2001 to 2018, using the related data between the Live Birth Information System (SINASC, acronym in Portuguese) and the Mortality Information System (SIM, acronym in Portuguese). The prevalence and infant mortality due to CA has increased in Brazil and in most regions, especially in the Northeast and North. CAs in the musculoskeletal system were the most frequent at birth (29.8/10,000 live births), followed by those in the circulatory system (12.7/10,000 live births), which represented the primary cause of death in this group. The applied linkage technique made it possible to correct the national prevalence of CA by 17.9% during the analyzed period, after retrieving the anomalies reported in SIM, thereby proving to be a good tool to improve the quality of information on anomalies in Brazil.

Resumo As anomalias congênitas (AC) configuram um relevante problema para a saúde pública global, afetando em média de 3% a 6% dos recém-nascidos em todo o mundo. No Brasil, ocupam a segunda posição entre os principais grupos de causas de óbito infantil. Assim, estudos amplos são necessários para mostrar o impacto das AC na saúde infantil. O presente estudo descreve a tendência temporal da prevalência e da mortalidade infantil por AC entre nascidos vivos (NV) no Brasil e em suas cinco regiões de 2001 a 2018, utilizando dados vinculados entre as bases de dados do Sistema de Informações sobre Nascidos Vivos (SINASC) e do Sistema de Informações sobre Mortalidade (SIM). A prevalência e mortalidade infantil por AC mostrou-se crescente no Brasil na maioria das regiões, principalmente no Norte e no Nordeste. Aquelas do aparelho osteomuscular foram as mais prevalentes ao nascimento (29,8/10.000 NV); as do aparelho circulatório passaram para a segunda posição (12,7/10.000 NV) após a vinculação das bases e representam a primeira causa de morte desse grupo. A técnica de vinculação de dados aplicada corrigiu a prevalência nacional das AC em 17,9% no período analisado, após serem recuperadas as AC notificadas no SIM, mostrando ser uma boa ferramenta para melhorar a qualidade das informações das AC.

Abstract Introduction Head and neck cancer (HNC) and its treatment can cause physical, psychological, and quality of life (QoL) damage, because it can disturb the physiology of eating, breathing, speaking, and compromise self-image. Objective To evaluate the QoL of the pretreatment of patients diagnosed with head and neck cancer according to the anatomical location of the tumor. Methods A descriptive, cross-sectional study was performed on a sample of 144 patients undergoing pretreatment for cancer from February 2017 to July 2019. The University of Washington QoL Questionnaire (version 4) was used to assess the QoL. The anatomical location data were obtained from medical records. The ANOVA test was used to compare the differences in QoL according to tumor location. Results A total of 144 participants were included, 66 (45.5%) of whom had the primary tumor located in the mouth. The median age of the patients was 62 years, with a higher prevalence of male (75.7%), Black (78.5%), single/divorced/widowed people (59%), and illiterates (32.6%); most of them were smokers (84.7%) and alcohol drinkers (79.2%). The mean QoL score was 830 for mouth cancer, 858 for pharynx cancer, and 891 for laryngeal cancer patients. Conclusion Based on the results of this study, it can be concluded that the QoL of patients with head and neck cancer was not influenced by tumor location. The most affected domains in the three groups were pain, appearance, chewing, swallowing, and speech (p < 0.05).

Abstract For oxide semiconductors for application in dye-sensitized solar cells (DSSCs), titanium dioxide conjugated with zinc oxide thin films was synthesized and characterized. The UV (ultraviolet) spectrum characterization showed a peak of absorbance at around 355 nm, with a band gap of 3.25 eV and reflectance around 85%. Such characteristics allowed the fabrication of DSSCs with N719 dye, under simulated light of 100 mW/cm2. The highest efficiency of 1.17% was at 5% titanium dioxide and 4 h of dye immersion.

Resumo A fertilização com lodo de esgoto desidratado pode acelerar o processo de recuperação de áreas degradadas devido à concentração de nutrientes, favorecendo o desenvolvimento de plantas pioneiras tais como Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) e de seus insetos. O objetivo deste trabalho foi avaliar os insetos mastigadores, polinizadores e predadores e seus índices e relações ecológicas em plantas de A. auriculiformis fertilizadas com lodo de esgoto desidratado, em área degradada, durante 24 meses. O delineamento foi inteiramente casualizados com dois tratamentos (com e sem adubação com lodo de esgoto desidratado) e 24 repetições (uma repetição = uma planta). O maior número de insetos mastigadores Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae) e Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), de desfolha, e do índice ecológico abundância de Coleoptera e de Orthoptera foram maiores em plantas de A. auriculiformis fertilizadas do que nas não fertilizadas com lodo de esgoto desidratado. Plantas de A. auriculiformis, com maior quantidade de galhos/árvore, apresentaram maiores abundâncias de Coleoptera e Orthoptera, riqueza de espécies de insetos polinizadores, desfolha e números de Parasyphraea sp. e T. collaris, e as com maior folhas/galho os de riqueza de espécies de Coleoptera e Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Por tanto, a utilização de A. auriculiformis, adubada com lodo de esgoto desidratado, é promissora na recuperação de áreas degradadas devido ao aumento dos índices ecológicos de insetos mastigadores, polinizadores e aranhas na área.

Abstract Fertilization with dehydrated sewage sludge can speed up the recovery process of degraded areas due to nutrients concentration, favoring the development of pioneer plants such as Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) and the emergence of insects. This study aimed the evaluation of chewing, pollinating insects, predators, their ecological indices and relationships on A. auriculiformis plants fertilized with dehydrated sewage sludge. The experimental design was completely randomized with two treatments (with and without dehydrated sewage sludge) and 24 repetitions. The prevalence of chewing insects Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae), and Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), defoliation, and ecological indices of abundance of Coleoptera and Orthoptera were observed on fertilized A. auriculiformis. Acacia auriculiformis plants, with a superior number of branches/tree, revealed greater abundance of Coleoptera and Orthoptera, species richness of pollinating insects, defoliation, numbers of Parasyphraea sp. and T. collaris. The ones with larger leaves/branches displayed greater abundance of species richness of Coleoptera and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Therefore, the use of A. auriculiformis plants, fertilized with dehydrated sewage sludge, is promising in the recovery of degraded areas due to the ecological indices increase of chewing and pollinators insects and spiders in the analyzed area.

Resumo A possível interferência de populações de pragas resistentes na ação de inimigos naturais ainda não foi esclarecida. Assim, este trabalho teve como objetivo avaliar o desempenho de Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) em ovos de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) com frequência de resistência à Metaflumizona ao longo de seis gerações de exposição ao produto. Cartelas (2,0 x 7,0 cm) com ovos de duas populações de S. frugiperda, (resistente à Metaflumizona e outra suscetível), foram expostas às fêmeas de T. pretiosum por 24 horas em condições de livre escolha e sem chance de escolha por três gerações (G1, G4 e G6). O delineamento experimental foi inteiramente casualizado com 25 repetições, sendo cada repetição composta por uma cartela (unidade experimental) contendo 20 ovos. Os parâmetros avaliados foram: parasitismo (%), emergência (%), razão sexual, número de parasitoides emergidos por ovo e longevidade de machos e fêmeas. ANOVA e teste de Tukey (P≤ 0,05) foram aplicados aos dados coletados. Os resultados mostraram redução do parasitismo [41,0% (G1) e 28,4% (G4)], emergência de ovos (17,5%) e parasitoides/ovo [16,2 (G4) e 17,2 (G6)] em ovos oriundos da população com frequência de resistência. As fêmeas emergidas de ovos da população G6 sem exposição à Metaflumizona, tiveram maior longevidade (3,5 dias a mais) do que a população exposta ao inseticida. A razão sexual e a longevidade de machos não foram afetadas. Os resultados indicam uma redução na atividade de T. pretiosum se as populações de S. frugiperda apresentarem alguma frequência de resistência à Metaflumizona.

Abstract The possible interference of resistant pest’s populations to insecticides in natural enemies in the action thas not been clarified yet. Thus, this study aimed to evaluate Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) performance on Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) eggs with resistance frequency to the Metaflumizone over six generations of product exposure. Egg cards (2.0 x 7.0 cm) containing eggs from two populations of S. frugiperda, (resistant to Metaflumizone and the other susceptible), were exposed to T. pretiosum females for 24 hours in free-choice and no-choice testing in three generations (G1, G4, and G6). A completely randomized experimental design was used with 25 replications, each consisting of an egg card (experimental unit) containing 20 eggs. The parameters evaluated were: parasitism (%), emergence (%), sex ratio, number of emerged parasitoids per egg and males/females longevity. ANOVA and Tukey test (P≤ 0.05) were applied on the results. Results showed a reduction in parasitism [41.0% (G1) and 28.4% (G4)], egg emergence (17.5%) and parasitoids/egg [16.2 (G4) and 17.2 (G6)] in eggs originating from the population with resistance frequency. Females emerging from G6 populations eggs without exposure to Metaflumizone had greater longevity (3.5 days more) than the resistant population. The sex ratio and male longevity were not affected. The results indicate a reduction in T. pretiosum activity if S. frugiperda populations have some frequency of resistance to Metaflumizone.

The objective of this study was to evaluate the chemical composition and in situ degradability of elephant grass silage dry matter with increasing levels of sugarcane bagasse. A completely randomized design was adopted with five treatments: 0, 5, 10, 15, and 20% inclusion of sugarcane bagasse on an as-fed matter basis, with five replications, totalling 25 experimental units. The increasing proportion of sugarcane bagasse analysed was favourable only in increasing the concentration of dry matter and fibre of silages and in maintaining a considerable crude protein content. In the in situ degradation assay, the addition of sugarcane bagasse in silage decreased the ruminal degradability of dry matter, and as the passage rates increased, the effective degradability decreased. In the in vitro gas production assay, the total production of gases was decreased with the inclusion of sugarcane bagasse, as did the degradability of organic matter and neutral detergent fibre. The recommendation for the inclusion of sugarcane bagasse should be analysed according to the desired objective, emphasizing that values higher than 5% can greatly compromise the final nutritive value of elephant grass silage.

ABSTRACT Afforestation of sites disturbed after bauxite mining is the favorite technique to restore all ecosystem functions. The nature of the tree species used for revegetation of post-mining land can accelerate the recovery of soil organic matter and nutrient cycles. This study aimed to determine the litterfall production, decomposition rate and nutrient content from three types of forest cover ( Eucalyptus , Anadenanthera peregrina , mixed plantation of 16 native species) planted in a bauxite mining area in recovery. Litterfall production was evaluated monthly over 30 months, and the litter mass was assessed twice a year (dry and rainy periods). Total nutrient content was determined from samples grouped by period (dry and rainy). The annual average values for litterfall dry mass and litter mass were higher in Eucalyptus and mixed native. The period (dry or rainy) did not influence litterfall rates in A. peregrina , but Eucalyptus and mixed native presented higher amounts for litterfall during the rainy and dry periods, respectively. Litter accumulation in Eucalyptus was not affected by the season of the year, but mixed native and A. peregrina presented higher litter accumulation in the dry season. Apparent decomposition rates of A. peregrina and mixed native were higher in the rainy season, highlighting the A. peregrina with the highest values compared with the other forest covers. The mixed native presented the highest leaf content of P, K, Ca and Mg in both the litterfall and litter mass, while Eucalyptus had the lowest P, K, Ca, S and N content and the highest C content in the litterfall. Litterfall production is important in degraded areas to ensure the nutrient return to the soil. The data obtained suggest that the cultivation of a mixed of 16 native trees contribute for produce the higher annual litterfall yields, besides produces leaf litterfall of better nutritional quality in relation to P, K, Ca, Mg and S. Therefore, mixed of native trees can be a promising option for reactivation of nutrient cycling and organic matter formation in mined area of bauxite in the Brazilian Atlantic Forest.
