The effect of dietary nitrate and canola oil alone or in combination on fermentation, digesta kinetics and methane emissions from cattle
(Elsevier, 2020-01)Nitrate and lipids have been recognized as effective dietary additives to reduce enteric methane (CH4) production. The objective of this experiment was to evaluate the effects of nitrate (NO3¯) and canola oil, alone or in ... -
Effect of Drosophila suzukii on Blueberry VOC’s: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae
(Springer, 2021-07)Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to find their hosts. However, this chemical landscape may be altered by the invasion of exotic insect ... -
Effect of egg production dynamics on the functional response of two parasitoids
(Plos ONE, 2024-03)Functional response describes the number of hosts attacked by a parasitoid in relation to host densities and plays an important role by connecting behavioral-level processes with community-level processes. Most functional ... -
Effect of GnRH or hCG administration on Day 4 post insemination on reproductive performance in Merino sheep of North Patagonia
(Elsevier, 2018-12)Different therapeutic strategies have been used with the objective of improve luteal function to reduce embryonic losses. The objective of this work was to study the effect of the administration of GnRH or hCG at Day 4 ... -
Effect of perforation on drying kinetics of Rosa rubiginosa fruits
(Asian Academic Research Associates, 2015-10)The effect of perforation and drying air operating variables on drying kinetics of Rosa rubiginosa fruits was investigated. Before drying, half the fruit sample was perforated in order to speed up the drying process. Samples ... -
Effect of plant nutritional traits on the diet of grasshoppers in a wetland of Northern Patagonia
(Taylor & Francis, 2020-05)Dichroplus maculipennis is one of the most damaging grasshoppers of wetlands. We investigated their feeding behavior in relation to the most abundant plants of Patagonian wetlands. Results showed that D. maculipennis was ... -
Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes
(Elsevier, 2019-11)The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ... -
The effect of silvicultural management on the genetic diversity of a mixed Nothofagus forest in Lanín Natural Reserve, Argentina
(2016-03)El conocimiento del impacto de las prácticas de manejo forestal es crucial para permitir el uso de los recursos naturales garantizando al mismo tiempo la sostenibilidad de la variación genética, que es esencial para la ... -
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: ... -
