Willows in Patagonia: the challenge of understanding and controlling invasions
(Universidad Autónoma del Estado de México (UAEMEX), 2021)Exotic willows are widely spread throughout Patagonia due to their vegetative multiplication, rapid growth, and ease for establishing themselves in environments with fluctuating hydric regimes, so they most commonly overgrow ... -
Wind disrupts trail pheromone communication in the leaf-cutting ant Acromyrmex lobicornis
(Elsevier, 2022-10)Although wind is a ubiquitous component of ecological systems and might affect pheromone communication, its effects have not been studied in depth. To test whether wind impacts trail pheromone behaviour, we studied the ... -
A wind-tunnel study on saltation and PM10 emission from agricultural soils
(Elsevier, 2016-09)PM10 emission depends on the texture and the aggregation state of a soil. A decisive but less studied factor is the saltation fraction of the soil (fraction between 100 and 500 μm). Six soils of contrasting textures were ... -
Winter cover crops in soybean monoculture: effects on soil organic carbon and its fractions
(2016-08)The current agricultural production systems in the Pampas Region have been significantly simplified by cultivating large land areas under no tillage (NT), where soybean is the predominant crop. These systems with long ... -
Winter injury to grapevine secondary phloem and cambium impairs budbreak, cambium activity, and yield formation
(Springer, 2019-11-11)Vitis vinifera is a species of temperate origin that reactivates the dormant secondary phloem from the previous year at the resumption of growth in spring. Following harsh winters, grapevines may display a set of symptoms ... -
Winter population size estimations of three migratory sheldgeese in the southern pampas, Argentina
(2018-03)Sheldgeese [Upland Goose (Chloephaga picta picta), Ashy-headed Goose (C. poliocephala) and Ruddyheaded Goose (C. rubidiceps)] have similar migratory patterns, breeding in Patagonia (Argentina and Chile) and wintering mainly ... -
Wireless wine: estimación de rendimiento y ubicación de sensores para la predicción de heladas en los viñedos
(Universidad Nacional de la Patagonia Austral, 2020-06)Los productores de viñedos han estado reuniendo información operacional significativa sobre sus campos, y las fincas más avanzadas pueden producir varios años de datos sobre cómo se ha plantado, regado, fertilizado y cómo ... -
Within-population variability in architectural traits and suitability to forestry conditions in Nothofagus nervosa (= N. alpina; Nothofagaceae)
(2013-07)Context: There is evidence that Nothofagus nervosa (= N. alpina) is suitable for timber production in temperate regions due to its wood quality and fast growth. However, high intra-specific variability in the architectural ... -
Wood anatomy, fire wounds and dendrochronological potential of Prosopis pugionata Burkart (Fabaceae) in arid Argentine Chaco
(International Association of Wood Anatomists, 2021-02)Prosopis pugionata (Fabaceae) is a halophyte tree species that grows exclusively in Argentina’s arid environments, whose woodlands are mainly affected by fires and overgrazing. Here, we describe the wood anatomy and fire ... -
Wood density and anatomy of three Eucalyptus species: implications for hydraulic conductivity
(2017)Aim of the study: To characterize wood anatomical traits of three Eucalyptus species that differ in wood density and ecological requirements, and to examine the relationships between some anatomical features, wood density, ... -
Wood density proxies of adaptive traits linked with resistance to drought in Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)
(Springer, 2014-10)A comparison of dead and surviving Douglas fir trees following the 2003 drought was made to define proxies of adaptive traits for resistance to drought. Increment cores were sampled from trees from three French regions: ... -
Wood phenotyping tools: properties, functions and quality : Reporte técnico final. Período que cubre este reporte: desde el 01/04/2015 al 31/03/2019
(EEA Bariloche, INTA, 2020-09)Muchos aspectos de la ecología de bosques y la cadena de valor de la industria forestal se relacionan con propiedades de la madera. Estas propiedades se pueden optimizar mediante mejoramiento genético, operaciones silvícolas ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ... -
Wood technologies and uses of Eucalyptus wood from fast grown plantations for solid products
(Society of Wood Science and Technology, 2008)The forest plantations are replacing the native forest in the wood provision for industries. At world-wide level almost 50% of the provision comes from plantations (IUFRO, TAIPEI 2007), being much greater in the South Cone ... -
Wood trait trade-offs in desert plants: A triangular model to understand intra- and interspecific variations along an aridity gradient
(Wiley, 2023-03-20)The hydraulic architecture of woody plants may show intra- and interspecific variations along aridity gradients as a result of wood trait trade-offs, which depend on species-specific abilities to withstand or evade drought. ... -
Wood waste characterization for composting
(ISHS, 2009)Use of composted wood wastes has beneficial effects on soil physical and chemical conditions and on crop productivity. This paper includes compositional data from thirteen different wood industry wastes, including bark, ... -
Workshops for the Construction of a Communication Strategy from a Multidimensional Approach

Worldwide diversity of endophytic fungi and insects associated with dormant tree twigs
(Springer, 2022-03)International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated ... -
Worldwide host associations of the tick genus Ixodes suggest relationships based on environmental sharing rather than on co-phylogenetic events
(BioMed Central, 2023-02-21)This study aims to capture how ticks of the genus Ixodes gained their hosts using network constructs. We propose two alternative hypotheses, namely, an ecological background (ticks and hosts sharing environmentally available ... -
