Abstract:
... The focus of the present study is the estimation of leaf area index (LAI) and the assessment of allometric equations for predicting the leaf area of Lebanon oaks (Quercus libani Oliv.) in Iran’s northern Zagros forests. To that end, 50 oak trees were randomly selected and their biophysical parameters were measured. Then, on the basis of destructive sampling of the oak trees, their specific l ...

Abstract:
... Previous efforts to estimate the daily energy expenditure of American Black Ducks (Anas rubripes) have relied upon diurnal behavior observations or predictive allometric equations. American Black Duck behavior was quantified during morning crepuscular, diurnal, evening crepuscular and nocturnal periods to create a 24-hr time-energy budget. Behaviors and energy expenditure differed between periods ...

Asellus aquaticus; abdomen; allometry; developmental stages; females; growth retardation; head; males; periodicity; population growth; vertebrates
Abstract:
... 1 In the relative growth of various width dimensions and total length in Asellus aquaticus the mean course of the later stages of growth shows simple allometry. 2 In detail, however, the growth‐curves show a regular rhythmicity which is essentially similar in all segments. It is suggested that the rhythmicity may be due to cyclic phenomena in absolute growth, the periodicity of the cycles in width ...

Abstract:
... In tropical forests, the high proportion of trees showing irregularities at the stem base complicates forest monitoring. For example, in the presence of buttresses, the height of the point of measurement (HPOM) of the stem diameter (DPOM) is raised from 1.3 m, the standard breast height, up to a regular part of the stem. While DPOM is the most important predictor for tree aboveground biomass (AGB) ...

Abstract:
... Morphological differences between the Neandertal and modern human glenoid fossa are mostly attributed to functional factors. However, the intimate relationship between the pectoral girdle and the shape of the thorax on which it rests calls for a structural analysis of the morphology of the glenoid fossa. Using both 3D Geometric Morphometric techniques and classical osteometry we carry out an analy ...

Abstract:
... Laser point cloud provides a high-precision data source for the 3D model reconstruction of existing trees. However, due to the complexity of tree structure and the data missing of point cloud, it is difficult to reconstruct complete, detailed and accurate 3D tree models from discrete points, especially the points are incomplete due to single-view scanning. To this end, a new point cloud driven met ...

Plant geometry can be described at several scales. At the finest scale, canopy structure includes the shape, size, location, and orientation of each organ in the canopy. This data set reports the three‐dimensional (3‐D) geometry of a set of f ...

Abstract:
... A functional–structural plant growth model was used to explore how selection might influence the ontogenetic patterns in three‐dimensional (3‐D) growth of trees. The 3‐D plant structure is defined by the orientation of metamers. The dynamics in the 3‐D plant structure depend on the production of metamers and/or leaf pipes and the loss of such plant components. In the simulations, metamer and leaf‐ ...

Abstract:
... Tropaeolum majus L., popularly known as nasturtium, is a species widely used in the form of infusions and salads. In the last years, the antihypertensive, diuretic, and calcium and potassium sparing activities of T. majus preparations were shown. Moreover, no preclinical 90-day oral toxicity studies were conducted. Thus, this study evaluated the toxicity of the hydroethanolic extract obtained from ...

Abstract:
... The Allometrically Constrained Growth and Carbon Allocation (ACGCA) model is an individual-based model of tree growth and mortality, and it is a unique tool for investigating how tree functional traits influence growth and mortality. Several studies have used the ACGCA model to investigate tree traits, but the model is not readily accessible to the wider scientific community. Thus, we developed an ...

Abstract:
... Increased forest productivity has been obtained by improving resource availability through water and nutrient amendments. However, more stress-tolerant species that have robust site requirements do not respond consistently to irrigation. An important factor contributing to robust site requirements may be the distribution of biomass belowground, yet available information is limited. We examined the ...
