Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): multidisciplinary research initiative involving than 30 partner organizations working assess both social and ecological dimensions of land-use sustainability eastern Brazilian Amazonia. The approach adopted by RAS offers three advantages for addressing problems: (i) collection synchronized co-located socioeconomic data...
Do the influences of river breezes or other mesoscale effects lead to a systematic proximity bias in Amazon rainfall data? We analyzed for network 38 rain gauges located near confluence Tapajós and rivers eastern Basin. Tipping bucket worked adequately regime, but careful field calibration comparison with collocated conventional were essential incorporate daily totals from our array into regional maps. Stations very large miss afternoon convective rain, as expected if breeze promotes...
Organic matter plays an important role in many soil properties, and for that reason it is necessary to identify management systems which maintain or increase its concentrations. The aim of the present study was determine quality quantity organic C different compartments fraction Amazonian ecosystems. (FSOM) fractionated stocks were estimated primary forest (PF), pasture (P), secondary succession (SS) agroforestry system (AFS). Samples collected at depths 0-5, 5-10, 10-20, 20-40, 40-60,...
There is a great need to identify interactions among silvopastoral systems and microclimatic indicators that describe the effect of trees compared conventional pasture without trees. The objective this study was evaluate thermal conditions in system area exposed full sunlight eastern Amazon, Brazil. composed forest tree species Bertholletia excelsa H.B.K., Dipteryx odorata (Aubl.) Willd, Khaya grandifoliola C.DC.. During monitoring period, inventory carried out included 30 from each for...
The Tapajós National Forest (FLONA Tapajós) has 600,000 hectares of protected forest, and is situated 50 km south the city Santarém, Pará, Brazil, a port 250,000 inhabitants that located at confluence Amazon Rivers. There lot farmland in region, which offers many opportunities to study changes land use. Selective wood harvesting one type use particularly important economy Santarém. Wet dry deposition organic material can be an source nutrients for plants, this especially true when soil poor,...
Afforestation with Eucalyptus species is increasing in Brazil, but there little information on the impacts of intensively managed short-rotation forestry soil aggregate dynamics and labile organic matter fractions these tropical ecosystems. This study investigated a clay sandy soil, each plantation an adjacent primary forest. It shown that silviculture alters processes formation both types. Micro-aggregates at 0–20 cm depth planted were 40% greater mass than under native forest, C N reduced...
This study aims to was a clinical case report relating the use of infrared thermography (IR) associated ozone therapy as complementary tools diagnose and treat non-infectious inflammatory process in locomotor system an athlete-horse Amazon. The heart rate (HR), respiratory (RR), rectal temperature (RT) were measured both rest after walking. Radiographic evaluation, complete hemogram creatine phosphokinase dosage (CPK) primarily conducted. IR examination additionally undertaken, thermograms...
Eucalyptus grandis and other clonal plantations cover about 3.5 million ha in Brazil. The impacts of intensively-managed short-rotation forestry on soil aggregate structure Carbon (C) dynamics are largely undocumented tropical ecosystems. Long-term sustainability these systems is probably part linked to maintenance organic matter good aggregation, especially areas with low-fertility soils. This study investigated a clay sandy soil, each plantation an adjacent primary forest. Silvicultural...
The objective of this study was to systematize a method that describes the dynamic processes exist in space and time related production chain ceramic industry center Iranduba, Amazonas, Brazil, through use mandala. A map possible conditioning factors can be characterized as links or problems constructed, consisted seven variables subdivided into three levels stratify descriptive steps chain. mandala constructed order describe historical aspects well integrate biophysical economic such soil...
The goal of this work is to compare the main air turbulence characteristics two common areas in Amazonian landscape: a dense forest (rough surface) and water surface (smooth surface). Using wind components data collected at high frequency by sonic anemometers located just above these surfaces, intensity power spectra, temporal length scales eddies, as well terms TKE budget (TKE = turbulent kinetic energy) were evaluated for each type. results showed that general, was higher than lake during...
Livestock systems have been identified as major emitters of greenhouse gases due to the use extensive areas with degraded pastures. The objective this study was analyze carbon (CO2) and methane (CH4) fluxes in atmosphere indicators environmental sustainability silvopastoral systems. CO2 CH4 from soil were monitored a pasture (predominant species: Panicum maximum cv. Mombaça) grown full sun compared tree species (Bertholletia excelsa, Dipteryx odorata, Khaya grandifoliola) productive (Panicum...
Twenty female Murrah buffaloes between four and five years old were randomly distributed into two groups (traditional system - TS silvopastoral SPS) with 10 animals each an average weight of 377.78 kg 356.10 kg, respectively, for the SPS. The had a management regime no canopy cover shade coverage over drinking feeding troughs. In SPS, Racosperma mangium (Fabaceae) trees used to provide shade, estimated 10% shading. physiological variables studied rectal temperature respiratory frequency...
A precipitação é uma importante fonte de entrada nutrientes para ecossistemas, principalmente em floresta tropical, que depende extremamente dessa a sua sobrevivência. pesquisa objetivou quantificar os fluxos potássio (K+), fósforo (P), cálcio (Ca2+), magnésio (Mg2+) e ferro (Fe2+) presentes na direta (PD) interna (PI), também verificar influência do efeito borda composição química da PI. O estudo foi realizado Floresta Nacional Tapajós (FLONA Tapajós), no município Belterra, Pará, zona...
Land-use change in the Amazon basin has occurred at an accelerated pace during last decade, and it is important that effects induced by these changes on soil properties are better understood. This study investigated chemical, physical, biological of a field under cultivation soy rice, adjacent primary rain forest. Increases bulk density, exchangeable cations pH were observed soil. In forest, microbial biomass basal respiration rates higher, community was metabolically more efficient. The sum...
Multiscalar topography influence on soil distribution has a complex pattern that is related to overlay of pedological processes which occurred at different times, and these driving forces are correlated with many geomorphologic scales. In this sense, the present study tested hypothesis whether multiscale geomorphometric generalized covariables can improve pedometric modeling. To achieve goal, case applied Random Forest algorithm database predict surface attributes. The area in phanerozoic...
The Brazilian Amazon has a large bovine herd and is an important exporter of meat from cattle also one the most competitive regions for exportation animal protein. Conventional extensive ranching management been strategy promoted by public policies contributed to processes occupation region through modification lands with native forests. objective this study was analyze fundamental elements that have sustained conventional in demonstrate new strategies change paradigm, focus on western Pará....
Objetivou-se identificar padrões térmicos no sistema solo-planta-animal usando a termografia infravermelho para subsidiar estratégias de melhoria pecuário em propriedade rural oeste do Pará. Foram realizadas capturas imagens termográficas dos seguintes alvos: animal, pastagem, solo e floresta secundária, mês agosto 2017. Dados climáticos foram analisados, considerando-se série histórica homogênea (1979 2009), bem como dados agrometeorológicos avaliar as condições tempo dia das coletas campo....
The Brazil nut tree ( Bertholletia excelsa Bonpl) is a well-studied species, and most studies conducted on it have been done in its natural habitat, dense ombrophilous forest. However, there lack of information about the biology this species deforested areas, such would be useful for management conservation. objective research was to compare flowering fruiting trees two areas with different vegetation cover (forested deforested) relate possible explanatory environmental factors. A total 120...
