(Facultad de Ciencias, 2015)Se realizó un ensayo para evaluar los insecticidas indoxacarb y rynaxypyr, en comparación con un tratamiento estándar de lambdacihalotrina sobre Heliothis (Helicoverpa) zea (Boddie), una plaga severa en maíz fresco en la ... -
Evaluation of modeling strategies for assessing self-thinning behavior and carrying capacity
(WILEY, 2018)Self-thinning and site maximum carrying capacity are key concepts for understanding and predicting ecosystem dynamics as they represent the outcome of several fundamental ecological processes (e.g., mortality and growth). ... -
Evaluation of root systems of seven peach rootstocks
(Facultad de Ciencias, 2012)The objective of this study was to evaluate and compare root distribution and length, using 8-year-old peach trees planted in a sandy loam of medium depth and good drainage, with drip irrigation in Paine (Chile). The ... -
Evaluation of rust pathogenicity (Phragmidium violaceum) as a biological control agent for the invasive plant Rubus ulmifolius on Robinson Crusoe Island, Chile
(SPRINGER, 2019)Rubus ulmifolius is a highly invasive species that negatively affects biodiversity, especially on Robinson Crusoe Island (RCI), one of the two global mini-hotspots of vascular plants. The rust Phragmidium violaceum has ... -
Evaluation of the Abundance of DNA-Binding Transcription Factors in Prokaryotes
(MDPI, 2020)The ability of bacteria and archaea to modulate metabolic process, defensive response, and pathogenic capabilities depend on their repertoire of genes and capacity to regulate the expression of them. Transcription factors ... -
Evaluation of the health status of Araucaria araucana trees using hyperspectral images
(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2018)The Araucaria araucana is an endemic species from Chile and Argentina, which has a high biological, scientific and cultural value and since 2016 has shown a severe affection of leaf damage in some individuals, causing in ... -
Evenness mediates the global relationship between forest productivity and richness
(WILEY, 2023-06)Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, ... -
