ABSTRACT: Increasingly, fast-growing forest plantations are able to support the wood supply but may simultaneously reduce water availability. The trade-off between wood production and water supply is more evident in areas with low water availability, high seasonal variation, or high water demand from local communities. The management regime adopted in forest plantations can either increase or reduce this trade-off. Thus, we assess herein the water and wood supply under different fast-growing forest plantation management regimes to understand how forest management practices can balance the provision of these services. The study was conducted at two catchments with a predominance of fast-growing forest plantations, namely, the mosaic management catchment (MMC) and the intensive management catchment (IMC). Rainfall and streamflow were monitored for three water years. Hydrological indexes were calculated to assess the hydrological regime of both catchments, and make inventories of the forest to assess forest growth rates. MMC had streamflow coefficients, baseflow index and baseflow stability higher than those of IMC. Mean annual wood increment was 32.73 m3 ha-1 yr-1 in MMC, with a mean age of 15 years, and 44.40 m3 ha-1 yr-1 in IMC at coppice in the second year. MMC hydrological indexes remained stable over the period studied, while in IMC the hydrological indexes were affected by climatic variations, mainly in drier years. MMC showed potential for supplying both water and wood. However, in IMC there was a trade-off between wood supply at the expense of the water supply. Thus, the intensity of fast-growing management can be adjusted to achieve a balance between water and wood supply on a catchment scale.

ABSTRACT Objective: to associate the presence and grading of adverse dermatoneurological events (peripheral neuropathy and hand-foot syndrome) and the interference in the activities of daily living of patients with gastrointestinal neoplasms undergoing systemic antineoplastic treatment. Method: this is a longitudinal, prospective study, using instruments to assess hand-foot syndrome and peripheral neuropathy. Results: there were 36 patients: 66.7% diagnosed with colon cancer and 83.2% on combination therapy. From cycle 5 onwards, all of them had hand-foot syndrome, with a majority of grade 1, unrelated to interference in activities of daily living. Regarding peripheral neuropathy, there was a moderate to strong correlation from cycle 1 of treatment. Conclusion: peripheral neuropathy negatively affects activities of daily living. The monitoring of dermatoneurological events by oncology nurses contributes to the clinical practice of nursing and subsidizes the development of advanced practice in the country.

RESUMEN Objetivo: asociar la presencia y gradación de eventos dermatoneurológicos adversos (neuropatía periférica y síndrome mano-pie) y la interferencia en las actividades de la vida diaria de pacientes con neoplasias gastrointestinales en tratamiento antineoplásico sistémico. Método: se trata de un estudio longitudinal, prospectivo, utilizando instrumentos para evaluar el síndrome mano-pie y la neuropatía periférica. Resultados: hubo 36 pacientes: 66,7% con diagnóstico de cáncer de colon y el 83,2% en terapia combinada. A partir del ciclo 5, todos presentaban síndrome mano-pie, en su mayoría grado 1, no relacionado con interferencia en actividades de la vida diaria. Con respecto a la neuropatía periférica, hubo una correlación de moderada a fuerte desde el ciclo 1 de tratamiento. Conclusión: la neuropatía periférica afecta negativamente las actividades de la vida diaria. El seguimiento de los eventos dermatoneurológicos por parte de los enfermeros de oncología contribuye a la práctica clínica de enfermería y subsidia el desarrollo de la práctica avanzada en el país.

RESUMO Objetivo: associar a presença e a graduação de eventos dermatoneurológicos adversos (neuropatia periférica e síndrome mão-pé) e as interferências nas atividades da vida diária de pacientes com neoplasias gastrointestinais em tratamento antineoplásico sistêmico. Método: trata-se de um estudo longitudinal, prospectivo, com a utilização de instrumentos de avaliação da síndrome mão-pé e da neuropatia periférica. Resultados: foram 36 pacientes: 66,7% com diagnóstico de câncer de cólon e 83,2% em terapia combinada. A partir do ciclo 5, todos apresentaram a síndrome mão-pé, com maioria de grau 1, não relacionada com a interferência nas atividades da vida diária. Em relação à neuropatia periférica, houve a correlação de intensidade moderada a forte desde o ciclo 1 de tratamento. Conclusão: a neuropatia periférica afeta negativamente as atividades da vida diária. O acompanhamento dos eventos dermatoneurológicos pelo enfermeiro oncológico contribui para a prática clínica da enfermagem e subsidia o desenvolvimento da prática avançada no país.

O objetivo deste trabalho foi avaliar o crescimento inicial da parte aérea e do sistema radicular, a nutrição mineral e a fixação biológica de N2 (FBN) em plantios consorciados de Eucalyptus grandis e leguminosas arbóreas. O delineamento experimental foi o de blocos ao acaso com três repetições e sete tratamentos por bloco. Nas linhas de plantio, entre as plantas de E. grandis, foram plantadas, intercaladamente, leguminosas arbóreas nativas de matas brasileiras - Peltophorum dubium, Inga sp., Mimosa scabrella, Acacia polyphylla, Mimosa caesalpiniaefolia - e uma leguminosa exótica, Acacia mangium. Realizou-se, também, o plantio puro de E. grandis. Mimosa scabrella e A. mangium foram as leguminosas com maior crescimento. Eucalyptus grandis consorciado com M. scabrella cresceu menos, no entanto foi o povoamento com maior acumulação de biomassa. As densidades de raízes finas (DRF) do E. grandis foram 6 a 20 vezes maiores que as DRF das leguminosas na camada superficial do solo (0-10 cm) 24 meses após plantio. A DRF de M. scabrella e de M. caesalpiniaefolia foi maior na camada 30-50 cm e menor na camada 10-30 cm. Os valores de delta15N da M. scabrella indicam que 90% do N acumulado em seus tecidos é oriundo da FBN.

The objective of this work was to assess interactions between species on the above and belowground growth, nitrogen uptake and biological nitrogen fixation (BNF) in mixed stands of Eucalyptus grandis and native leguminous N2-fixing trees. A complete randomized block design was installed with seven treatments and three blocks. Within the lines of the E. grandis seedlings, native leguminous N2-fixing trees - Peltophorum dubium, Inga sp., Mimosa scabrella, Acacia polyphylla, Mimosa caesalpiniaefolia - and one exotic leguminous plant, Acacia mangium, were intercropped. E. grandis was also solely planted. Mimosa scabrella and A. mangium were the legume trees that presented the highest growth. Although E. grandis showed a lower growth when combined with M. scabrella, this mixed-species stand exhibited the highest biomass accumulation. Eucalyptus grandis fine root densities (FRD) were 6-20 times higher than the FRD of the leguminous species in the upper soil layer (0-10 cm) 24 months after planting. The FRD of M. scabrella and M. caesalpiniaefolia in the 30-50 cm soil layer was higher than in the 10-30 cm layer. The delta15N values of M. scabrella indicated that 90% of stocked N is derived from BNF.
