Effect of stand density and pruning on growth of ponderosa pines in NW Patagonia, Argentina
(2010-03)Due to the lack of knowledge about ponderosa pine performance under silvopastoral systems (SPS) conditions, the objective of this study was to determine the effect of stand density and pruning on the growth magnitude of ... -
Effect of structural modifications on the drying kinetics of foods: changes in volume, surface area and product shape
(ISEKI Food Association, 2013-10)Macro and micro-structural changes take place during food dehydration. Macro-structural changes encompass modifications in shape, area and volume. Studies of such changes are important because dehydration kinetics (essential ... -
Effect of temporal and spatial noise colour in insect outbreak frequency
(Springer, 2023-06)Insect outbreaks are a common multicausal population phenomenon that is characterised by a fast growth of the population, followed by an equally sudden collapse in a relatively short period in the manner of an excitable ... -
Effect of vegetable oils as Phagostimulants in adults of Dichroplus vittigerum (Orthoptera: Acrididae)
(Entomological Society of America, 2019-12)Several species of grasshoppers are attracted to vegetable oils. These oils have kairomonal properties mainly due to the presence of linolenic and linoleic fatty acids. This study aimed to determine whether the odors of ... -
Effect of volcanic ash over Orthoptera survival in Patagonia
(2015-04)The aim of this work was to evaluate the ash toxicity from the Puyehue-Cordón Caulle volcanic complex on the survival of two Orthopteran species: the grasshoper Dichroplus vittigerum and the green locust Brugilis sp. Two ... -
Effects of climate on the radial growth of mixed stands of Nothofagus nervosa and Nothofagus obliqua along a precipitation gradient in Patagonia, Argentina
(Elsevier, 2022-08)Climate models for North Patagonia in Argentina project dryer conditions, due to a decrease in mean precipitation combined with an increase in mean temperatures. The temperate mixed Nothofagus forest, which exists along a ... -
Effects of elevated CO2 on the water hyacinth-biocontrol agent Megamelus scutellaris (Hemiptera: Delphacidae) and its yeast-like symbiotes
(Elsevier, 2024-01)Water hyacinth, Pontederia crassipes, is a highly invasive plant native to South America and one of the most invasive aquatic plants in the world. For its control, the planthopper Megamelus scutellaris Berg (Hemiptera: ... -
Effects of low-density Pinus elliottii (Slash pine) afforestation on environmental conditions and native plant diversity, in the mountains of central Argentina
(2018-07)Question: What effects do low-density afforestation with Pinus elliottii have on the site conditions and plant diversity of the mountains of central Argentina? Location: Sierra de Comechingones, central Argentina. Methods: ... -
Effects of polydopamine-passivation on the optical properties of carbon dots and its potential use in vivo
(Royal Society of Chemistry, 2020-07)Passivation of carbon dots via heteroatom doping has been shown to enhance their optical properties and tune their fluorescence signature. Additionally, the incorporation of polymeric precursors in carbon dot synthesis has ... -
Effects of pretreatments in convective dehydration of Rosehip (Rosa eglanteria)
(ISEKI Food Association, 2012-02)The aim of this work was to experimentally determine drying curves for thin layer and bed drying of rosehip fruits, with and without pretreatments, to reduce processing times as a function of drying air operating variables, ... -
Efficient sampling of ground-dwelling arthropods using pitfall traps in arid steppes
(Sociedade Entomológica do Brasil, 2010-12)Pitfall trapping is probably the most frequently used method for sampling grounddwelling arthropods. While the capture of specimens in pitfall traps largely depends on the number of individuals in the sampled area, trap ... -
