Mountain beech (Nothofagus solandri var. solandri) trunk diameters were measured in each of two catchments, a control, and a stream catchment (a putative lahar path), to assess the vulnerability of a hut sited on the Wakapapaiti Stream, Tongariro National Park, to disturbance events. Beech forest margins were more abrupt, terraced, and were adjacent to rocky areas in the stream catchment, while...

Tree species proportions of forest stands were estimated using ranging scatterometer called HUTSCAT. Employed estimation method was multilayer perceptron neural network with error backpropagation training algorithm. Two methods for feature extraction were tested; other based on intensity and shape of measured profiles, other only shape. Different neural network configurations were tried and it ...

Southern pines vary in their response to the loss of leaf area by crown scorch. We hypothesize that they tolerate crown scorch by at least three recovery mechanisms, but the function of these mechanisms is season-dependent. Using sapling longleaf pine as a model and experimental results from central Louisiana, U.S.A., our objective is to present examples recovery from scorch, and discuss how th...

Abstract In Mediterranean basin, citrus culture is expanding rapidly with a growing demand for high-quality saplings. Protected cultivation fine microclimate conditions control the best process of saplings required quality. this context, developed tunnel greenhouse and its effects on plant activity parameters, such as leaf temperature transpiration, were investigated. The findings show that tem...
