Transpiration/Evaporation Ratio in Prunus Fremontii and Marianna 2624 over a 4-Day Period of Drought
2017
Drought stress represents one of the major environmental limitations to crop production in a large portion of the Earth’s surface. Natural genetic resources are one of the most powerful weapons against environmental stress. In such contest, the behavior in terms of water loss of two species, P. fremontii (slower-growing) and Marianna 2624 (faster-growing), native to arid and humid regions respectively, was tested. Transpiration (T) and evapotranspiration (ET) rates and soil water content (SWC) were measured in the two species under controlled conditions. Evaporation rate from the soil surface was obtained by difference, and an average transpiration/evaporation ratio (T/E) was calculated to …
La coltivazione del mango nel Mediterraneo: dinamiche di crescita e variabili climatiche
2020
Se oggi la coltivazione del Mango in ambiente Mediterraneo è ormai una realtà consolidata, non bisogna dimenticare che, ai fini di un buon risultato in termini di attecchimento delle piante e di fruttificazione, occorre confrontarsi con le temperature i cui effetti sono in grado di influire fortemente sull’adattamento delle diverse cultivar modificandone la risposta vegeto-produttiva.

L'impianto, la gestione e la valorizzazione multifunzionale dei boschi periurbani
2014
I boschi periurbani, come tutti gli spazi verdi prossimi agli agglomerati urbani, migliorano le condizioni ambientali e la qualità dell'aria, contribuiscono alla conservazione della biodiversità, possono favorire l'aggregazione sociale. I boschi prossimi ai centri urbani rivestono inoltre un ruolo importante dal punto di vista paesaggistico e turistico e contribuiscono a contrastare i cambiamenti climatici. Questa pubblicazione, redatta con il supporto tecnico-scientifico dell'Accademia italiana di scienze forestali di Firenze, si propone di fornire linee guida per la progettazione, la realizzazione e la gestione dei boschi periurbani e delle fasce verdi nelle aree prossime agli agglomerati…
Organic waste materials for Bioengineering works
2016
Bioengineering uses plant and biodegradable materials of natural origin, stones, steel, additives and synthetic products in various combinations and as support for the growth of plants. The lack of available resources and progressive increasing of desertification in Sicily, led to the search for alternative materials. Objective of the work is testing organic waste materials for the realization of bioengineering works in the several areas of application: terrestrial, fluvial and coastline. To this aim, is proposed the use of innovative techniques that involve the construction of low-cost brushwood, environmentally friendly materials made: the pruning of vines and the oceanic Posidonia oceani…
Changes in Physicochemical Properties of Biochar after Addition to Soil
2022
It is recognized that biochar undergoes changes when it is applied to soils. However, the mechanisms of biochar alterations are not fully understood yet. To this purpose, the present study is designed to investigate the transformations in the soil of two different biochars obtained from pyrolysis of fir-wood pellets. The production of the biochars differed for the dry and wet quenching procedures used to terminate the pyrolysis. Both biochars were applied to clay soil (26% sand, 6% silt, and 68% clay) placed into lysimeters. After water saturation and 15 days of equilibration, seeds of watercress (Lepidium sativum) were cultivated. After a further 7 weeks, the biochars were manually separat…
Estimation of dynamic energy budget parameters for the Mediterranean toothcarp (Aphanius fasciatus)
2014
Organisms adopt different sets of physiological, behavioural and morphological trade-offs in order to cope with natural environmental fluctuations. This has consequential rebounds on ecological processes and population dynamics. Such aspects become crucial for sex-dimorphic species, where sex-specific growth variation could mirror different tactics both in energy acquisition and investment between maximum female and male body size with cascading effects on population demography. To date, different approaches have been used in order to understand the causes of individual growth rate changes in ectotherm indeterminate growers, most of which failed. Here, we propose the use of a mechanistic mo…

New applications in integrated fixed film activated sludge-membrane bioreactor (IFAS-MBR) systems
2020
Abstract This chapter provides an overview on the development and application of integrated fixed film activated sludge-membrane bioreactor (IFAS-MBR) systems. IFAS-MBRs represent a novel configuration for advanced wastewater treatment, and only a few studies are available in literature. With this aim, the results of some studies on IFAS-MBR systems already published are discussed and compared in this chapter. Literature shows that the influent carbon to nitrogen ratio (C/N) strongly affects the biological process in IFAS-MBR. The organic matter removal efficiency (removed biologically) decreases from 60% to 23.5% with the decrease of influent C/N from 10 to 2 mgCOD mgTN− 1. Nitrogen remova…
