Individuals of its own genus were the main food item of two species of tucunares (Cichla cf. ocellaris and Cichla monoculus) introduced into the Volta Grande Reservoir. The abundance of adult tucunares may cause intra-specific competition, possibly leading to the high cannibalism rates found.

introduction: appropriate definition of the distance measure between diffusion tensors has a deep impact on diffusion tensor image (dti) segmentation results. the geodesic metric is the best distance measure since it yields high-quality segmentation results. however, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. the main goal of this ...

This study examines the seasonal cycle of the components of the surface energy balance in the Volta basin in West Africa as part of the GLOWA-Volta project. The regional climate is characterized by a strong north–south gradient of mean annual rainfall and the occurrence of pronounced dry and wet seasons within one annual cycle, causing a strong seasonal variation in the natural vegetation cover...

Large-scale information retrieval evaluation efforts such as TREC and NTCIR have always used binary-relevance evaluation metrics, even when graded relevance data were available. However, the NTCIR-6 crosslingual task has finally announced that it will use graded-relevance metrics, though only as additional metrics. This paper compares graded-relevance metrics in terms of the ability to control ...
