Citrullus lanatus var. lanatus; watermelons; plant morphology; leaves; measurement; length; leaf area; grafting (plants); width; nondestructive methods; allometry; plant growth; cultivars; genetic variation; regression analysis; growth models; mathematical models; equations; model validation; Italy
Abstract:
... Leaf area estimation is an important biometrical observation one has to do for comparing plant growth in field and greenhouse experiments. Determining the individual leaf area (LA) of watermelon (Citrillus lanatus Thunb.) involves measurements of leaf parameters such as length (L) and width (W), or some combinations of these parameters. Two-year investigation was carried out during 2006 (on six cu ...

Abstract:
... BACKGROUND: Most current approaches in forest science and practice require information about structure and growth of individual trees rather than - or in addition to - sum and mean values of growth and yield at forest stand level as provided by classic experimental designs. By inventing the wheel design, Nelder provided the possibility to turn to the individual tree as basic information unit. Such ...

Abstract:
... We analysed ontogenetic shape change in the planorbid limpet Ancylus fluviatilis (Müller, 1774) in two rivers in Southern Italy. We developed a new method to discriminate among different cohorts in Ancylus , based on principal component analysis. The method is useful when shape change during growth is allometric, as in our study model. We discovered that bivoltinism occurs in Ancylus in Southern I ...

Abstract:
... Climate action plans, with goals for carbon neutrality of cities, often rely on estimates of urban forest biomass and related annual carbon sequestration balanced against citywide carbon emissions. For these estimates to be successful, there is a need both for accurate quantification of urban tree populations and structure, and consideration of the net carbon sequestered when the fate of wood wast ...

Abstract:
... Increased carbon dioxide (CO2) emissions in urban areas due to rapid population growth and consequent increased energy use and vehicular traffic is a worldwide problem contributing to an altered global climate. Studies from North America and Asia have reported that urban trees can be used to mitigate these emissions. However, little is known about the role of European urban streetscapes in mitigat ...

Abstract:
... Recently, the severe intensification of atmospheric carbon has highlighted the importance of urban tree contributions in atmospheric carbon mitigations in city areas considering sustainable urban green planning and management systems. Explicit and timely information on urban trees and their roles in the atmospheric Carbon Stock (CS) are essential for policymakers to take immediate actions to ameli ...
