Ecological and social impacts of photovoltaic solar power plants and optimization of their locations in northern Chile

2017

Large scale photovoltaic (PV) solar power plants are gaining popularity in Chile. Solar energy potential in northern Chile is one of the best worldwide and true deserts are considered ideal environments for solar power plant projects. Atacama Desert is one of the driest places on earth. Nevertheless, northern Chile is home for many endemic species with 40 different vegetation types. The thesis presents studies of ecological effects (I-II) and location optimization of PV solar power plants in northern Chile (III). For ecological impacts two types of PV solar power plant technologies were studied: fixed mount solar plant and solar- tracking mounts. Study units were placed below the mounts or …

El presente estudio pretende abrir una línea de estudios dedicada a las plantas, el mundo vegetal como tema del arte, en concreto la pintura. Un acercamiento preliminar al tema, utilizando como fuentes una breve selección significativa de la pintura española del siglo XVII.

Technical English for agriculture

2021

As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…

Effect of fertilization on growth of lingonberry (Vaccinium vitis-idaea L.)

2021

Received: January 29th, 2021 ; Accepted: April 10th, 2021 ; Published: April 20th, 2021 ; Correspondence: andis.karlsons@lu.lv Today, most of the global berry crop of Vaccinium vitis-idaea L. is obtained from wild berries. In recent years, however, their cultivation has become slightly more widespread, especially as demand has increased. As the commercial production of lingonberries is a completely new fruit-growing sector in Latvia, research on mineral nutrition, development of the crop production system and proper fertilizer management is critically important. The objective of this study was to elucidate the effect of different fertilizer rates on the nutrient status of lingonberry plant …

Rhynchophorus ferrugineus attack affects a group of compounds rather than rearranging Phoenix canariensis metabolic pathways.

2016

The red palm weevil (RPW; Rhynchophorus ferrugineus) is spreading worldwide and severely harming many palm species. However, most studies on RPW focused on insect biology, and little information is available about the plant response to the attack. In the present experiment, we used metabolomics to study the alteration of the leaf metabolome of Phoenix canariensis at initial (1st stage) or advanced (2nd stage) attack by RPW compared with healthy (unattacked) plants. The leaf metabolome significantly varied among treatments. At the 1st stage of attack, plants showed a reprogramming of carbohydrate and organic acid metabolism; in contrast, peptides and lipid metabolic pathways underwent more c…

Le infrastrutture ecologiche come elemento funzionale nella gestione della biodiversità degli agrosistemi, con particolare riferimento al vigneto

2013

Molti studiosi, già da diverso tempo, hanno messo in risalto l’importanza della diversità vegetale negli agroecosistemi sull’aumento della presenza di artropodi utili che contribuiscono al contenimento delle specie dannose. In quest’ambito una strategia di difesa per mantenere alto il livello di biodiversità riguarda l’uso delle cosiddette “infrastrutture ecologiche” o “aree di compensazione ecologica”, cioè siepi o fasce di vegetazione adiacenti al campo coltivato o al suo che forniscono ospiti alternativi e siti rifugio per predatori e parassitoidi di insetti dannosi, aumentando in tal modo l’abbondanza dei nemici naturali e la colonizzazione delle colture confinanti. Alcuni lavori di cam…

Laboratory evaluation of the effect of plant extracts on Tetranychus urticae Koch (Acariformes, Tetranychidae)

2005

Acetone extracts of Annona cherimola Mill., Melia azedarach L., Artemisia absinthium L. and Quassia spp., were tested in laboratory trials on young females of Tetranychus urticae Koch (Acariformes,Tetranychidae). In the post-infestation tests, extracts of Melia and Annona caused a high mortality of the target females (84% and 96% for Melia and Annona, respectively) after 24 hours and 100% for both extracts after 48 hours. On the other hand Artemisia extracts caused 84% mortality of females after 10 days even if the oviposition rate was statistically lower than in the controls (2.5 and 6.7 eggs/female/day for Artemisia and controls, respectively).

Characterization of Erwinia gerundensis A4, an Almond-Derived Plant Growth-Promoting Endophyte

2021

The rapidly increasing global population and anthropogenic climate change have created intense pressure on agricultural systems to produce increasingly more food under steadily challenging environmental conditions. Simultaneously, industrial agriculture is negatively affecting natural and agricultural ecosystems because of intensive irrigation and fertilization to fully utilize the potential of high-yielding cultivars. Growth-promoting microbes that increase stress tolerance and crop yield could be a useful tool for helping mitigate these problems. We investigated if commercially grown almonds might be a resource for plant colonizing bacteria with growth promotional traits that could be use…
