Variación local y geográfica de las infracomunidades de parásitos de la anchoveta Engraulis ringens en Chile
(2013)We compared the local and geographical variation of parasite infracommunities of the anchovy Engraulis ringens from 3 fishing areas off Chile (Caldera, Talcahuano and Valdivia), in 7 samples taken from different vessels. ... -
Variation in consumer pressure along 2500 km in a major upwelling system: crab predators are more important at higher latitudes
(2019-10-10)Consumer pressure in benthic communities is predicted to be higher at low than at high latitudes, but support for this pattern has been ambiguous, especially for herbivory. To understand large-scale variation in biotic ... -
Variation in habitat use along the freshwater-marine continuum by grey mullet Mugil cephalus at the southern limits of its distribution
(2015)In this study, habitat use by Mugil cephalus was investigated in the waters of the west coast of the North Island of New Zealand by analysing microchemical composition of otoliths (laser-ablation inductively coupled plasma ... -
Variation in tail morphology across urban and forest populations of the crested anole (Anolis cristatellus)
(2019-11)Anolis lizards are well known for their specialist ecomorphs characterized by the convergent evolution of suites of traits linked to the use of particular microhabitats. Many of these same traits evolve rapidly in response ... -
Variation of sterols and fatty acids as an adaptive response to changes in temperature, salinity and pH of a marine fungus Epicoccum nigrum isolated from the Patagonian Fjords
(2014)Se aisló e identificó una cepa hongo marino a partir de muestras de sedimentos obtenidas a partir de un sector de los fiordos patagónicos. La cepa LQRA39-P fue identificado como Epicoccum nigrum utilizando técnicas de ... -
Variation of suction pressure during caisson installation in sand
(2009)This work presents good-quality data on the installation of model suction caissons in dense silica sand. The tests were carried out in a beam centrifuge. The results are coherent with others ... -
Variation of the use of marine resources by Galaxias maculatus in large Chilean rivers
(2018-06)The objective of this study was to assess the frequency of use of marine resources in recruitment of Southern Hemisphere native riverine fish Galaxias maculatus from rivers across a latitudinal gradient. To do this, we ... -
Variational convergence for vector-valued functions and its applications to convex multiobjective optimization
(2013)The aim of this work is to study a notion of variational convergence for vector-valued functions. We show that it is suitable for obtaining existence and stability results in convex multiobjective optimization. We obtain ... -
Variations in soil aggregation, microbial community structure and soil organic matter cycling associated to long-term afforestation and woody encroachment in a Mediterranean alpine ecotone
(2022)Afforestation and subsequent expansion of trees on former grasslands may significantly impact the structure and activity of the soil microbial community, altering soil aggregation and affect its potential to store and ... -
Variations in soil chemical and physical properties explain basin-wide Amazon forest soil carbon concentrations
(2020-02-11)We investigate the edaphic, mineralogical and climatic controls of soil organic carbon (SOC) concentration utilising data from 147 primary forest soils (0–30 cm depth) sampled in eight different countries across the Amazon ... -
Vehicle Following Problem: A Control Approach for Uncertain Systems with Lossy Networks
(2018-09)In the present work, a control system based in Networked Control Systems is proposed, in order to provide a suitable solution to the vehicle following problem. This problem presents the two main obstacles: the first been ... -
Velocidad de marcha normal y máxima de adultas mayores asistentes a talleres de ejercicio físico de la Junta de Vecinos Santa Marta de la comuna de Talcahuano
(2018-12)La velocidad de marcha se reconoce como un factor determinante en la condición física en el adulto mayor. Las investigaciones respecto de esta cualidad física han permitido demostrar su importante asociación con la presencia ... -
La velocidad y el esfuerzo de corte inverso en dos secuencias consecutivas del tipo pozón-rápido a través del modelo numérico tridimensional Delft 3D-FLOW.
(2016-06)La presente investigación utiliza resultados hidráulicos tridimensionales obtenidos mediante Delft 3D-FLOW para evaluar la ocurrencia de velocidad de fondo inversa y esfuerzo de corte inverso a través de dos secuencias ... -
Velocidades críticas de nado de cheirodon galusdae y percilia irwini, a distintas temperaturas y tallas
(2016-07)Las especies nativas pocha (Cheirodon galusdae) y carmelita (Percilia irwini) que habitan en los sistemas fluviales de la VIII Región, se encuentran en estado vulnerable de conservación y peligro de extinción, respectivamente. ... -
Velocity loss thresholds reliably control kinetic and kinematic outputs during free weight resistance training
(2020-09)Exercise velocity and relative velocity loss thresholds (VLTs) are commonly used in velocity-based resistance training. This study aims to quantify the between-day reliability of 10%, 20%, and 30% VLTs on kinetic and ... -
