-During spring and early summer, shruband herbaceous-level vegetation provides nesting and foraging habitat for many shrub-habitat birds. We examined relationships among arthropod biomass and abundance, foliage leaf surface area and weight, vegetation ground cover, soil characteristics, relative humidity, and temperature to evaluate what factors may influence arthropod food resources for birds....

First rotation Pinus radiata D. Don trees were grown on a nitrogen-deficient sand dune in an experimental design that included lupin (Lupinus arboreus Sims) as an understory species, and biennial application of balanced fertilizer in a replicated split-plot factorial design with thinning treatments as subplots. From an initial 2222 stems ha(-1), stands were thinned to 1483 and 741 trees ha(-1) ...

Knowledge of temporal variations in radial profiles of sap flux density (Js) and its relation to canopy water vapour exchange would help to improve our understanding of plant water relations. In this study we aimed to test if there is a consistent radial profile of Js in olive trees under optimal soil water availability and severe water stress conditions. Furthermore, if the radial profile of J...

The usefulness of a probabilistic technique to describe 3D foliage geometrical traits depends on the possibility of quickly and cheaply collecting a leaf data sample. The present simulation study was designed to provide the statistical information necessary to drive and control a foliage random sampling process on a real tree canopy (considered as a population of leaves) and to evaluate two cor...

Convolutional neural networks (CNNs) have become popular especially in computer vision in the last few years because they achieved outstanding performance on different tasks, such as image classifications. We propose a ninelayer CNN for leaf identification using the famous Flavia and Foliage datasets. Usually the supervised learning of deep CNNs requires huge datasets for training. However, the...

Airborne synthetic aperture radar (SAR) operating in the VHF band and used in conjunction with change detection has shown promising results for wide-area surveillance of ground targets. By using VHF-band frequencies, both targets in the open as well as concealed by foliage may be detected in a robust manner. VHF-band SAR is able to detect hidden targets because both foliage attenuation and clut...

It is well known that occupational exposure to pollens of flowering ornamental plants may elicit rhinoconjunctivitis, asthma, and contact urticaria (1). However, it was not until the 1980s that a foliage decorative plant, weeping fig (Ficus benjamina), was recognized as an important cause of occupational immediate mucosal and skin reactions, and, to a lesser degree, of similar symptoms in atopi...
