13. TRANSITION FROM SYSTEMATIC TO DIRECTED SOIL SAMPLING DESIGNS IN AN AREA MANAGED WITH PRECISION AGRICULTURE
ABSTRACT In agricultural areas with a historical of systematic soil sampling, alternative methodologies such as directed sampling design based on management zones (MZ) have been proposed to reduce sampling costs. The aim of this study was to evaluate the technical and economic impacts of replacing a dense systematic soil sampling design (cell size of 0.5 ha)

14. The bony fishes (Teleostei) caught by industrial trawlers off the Brazilian North coast, with insights into its conservation
RESUMO A costa Norte do Brasil é um dos pesqueiros de camarão mais importantes do mundo, com uma área total de aproximadamente 223.000 km2. No entanto, dados disponíveis sobre a diversidade de peixes capturados pela frota industrial de arrasto de portas na região são limitados às espécies com valor comercial. Essa lacuna no conhecimento sobre a fauna

15. Turismo e participação social na gestão do Centro Histórico de Salvador (BA)
Resumo Cada vez mais próximo a setores empresariais, o turismo tem se tornado alvo de recorrentes críticas por se distanciar de setores sociais na elaboração e no acompanhamento de políticas públicas e/ou programas de recuperação de centros históricos, principalmente em áreas urbanas. Com base em recomendações internacionais, projetos de âmbit

17. Diversity of wasps (Hymenoptera: Aculeata: Vespidae) along an altitudinal gradient of Atlantic Forest in Itatiaia National Park, Brazil
ABSTRACT Surveying the diversity of stinging wasps (Hymenoptera: Aculeata) provides an important information base to assist in biodiversity conservation and the management of forest reserves, as wasps depend on and maintain the population balance of several other groups of insects. In accordance, this paper presents an altitudinal survey of wasps (Hymenopter

18. Crop Yield Responses to Sulfur Fertilization in Brazilian No-Till Soils: a Systematic Review
ABSTRACT Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertil

19. Morphological study of the gastrointestinal tract of Larimichthys crocea (Acanthopterygii: Perciformes)
ABSTRACT The present study aimed to investigate the macroscopic and histological structure of the gastrointestinal tract (GIT) of Larimichthys crocea (Richardson, 1846). It consists of esophagus, stomach regions, pyloric caeca, intestinal regions, and rectum. Sixteen tubular light yellowish pyloric caeca of similar sizes were observed in all individuals. The

20. Water extraction and implications on soil moisture sensor placement in the root zone of banana
ABSTRACT: The knowledge on spatial and temporal variations of soil water storage in the root zone of crops is essential to guide the studies to determine soil water balance, verify the effective zone of water extraction in the soil and indicate the correct region for the management of water, fertilizers and pesticides. The objectives of this study were: (i)

21. Spatial and temporal patterns of soil water content in an agroecological production system
ABSTRACT: Spatial and temporal patterns of soil water content (SWC) can not only improve the understanding of soil water processes but also the water management in the field. The spatial distribution of SWC depends on the spatial variability of soil attributes, vegetation and landscape features. The aim of this study was to evaluate: i) the spatial and tempo

22. Climatic Variation: Effects on Stress Levels, Feed Intake, and Bodyweight of Broilers
ABSTRACT Chickens tolerate a very narrow range of climatic variation, and therefore, it is essential to determine the most suitable climatic area and weather for broiler production in open-house systems. In this study, 3060 broilers were used as experimental birds to investigate the effects of seasonal differences and climatic variations on the growth perfor

23. Geo-environmental zoning using physiographic compartmentalization: a proposal for supporting sustainable decision-making
ABSTRACT The geo-environmental zoning represents an important strategy in the territorial management. However, it requires a logical and structured procedure. Therefore, an approach using physiographic compartmentalization is proposed and applied as case study in a region covered by the topographic maps of São José dos Campos and Jacareí, Brazil. This reg
