A thorough convergence analysis of the Control Reduced Interior Point Method in function space is performed. This recently proposed method is a primal interior point pathfollowing scheme with the special feature, that the control variable is eliminated from the optimality system. Apart from global linear convergence we show, that this method converges locally almost quadrat-ically, if the optim...

Abstract: Aim Evaluate the structure of aquatic macrophytes assembly Jacarecica II Dam, Areia Branca, Sergipe, and verify if distance from margin is a driver for species richness, composition in this environment. Methods We settled transects where we plotted quadrats subplots. The were perpendicular relation to reservoir margin, first quadrat was placed on with four following ones completely ov...

The 1 m2 quadrat is a standard field survey tool in ecology. Traditionally, researcher places square frame on the ground and manually records data about organisms (typically plants) within that quadrat. Collecting through this method can require great deal of time on-site. For some studies, it would be more efficient to collect as images field, then extract desired from later. Equipment current...

BACKGROUND AND AIMS The collection of field data on plant traits is time consuming and this makes it difficult to examine changing patterns of traits along large-scale climate gradients. The present study tests whether trait information derived from regional floras can be used in conjunction with pre-existing quadrat data on species presence to derive meaningful relationships between specific m...
