Festuca pallescens is a native forage grass species of Patagonia, playing crucial role in supporting sheep production arid and semi-arid ecosystems. This study assessed genetic differentiation among populations estimated the heritability traits linked to biomass phenological development as part its domestication effort. A common garden trial was established with ten half-sib families from four preselected populations, morphological were measured over three seasons. Trait correlations...
Rangelands play a crucial socioeconomic and environmental role worldwide. In South America, desertification overgrazing has led to their deterioration declining productivity. Breeding programs that use native forage species of economic ecological importance, such as Festuca pallescens (St. Yves) Parodi, may provide locally adapted germplasm enhances productivity without threatening local biodiversity. These even promote the conservation species. To this end, we characterized phenotypic...
Increasing risks of loosing forest genetic resources and the need for a sustainable quality wood supply make focusing research efforts on undomesticated tree species necessary.The study their variation in vegetative propagation ability development practical methodologies to obtain copies are essential tools conservation breeding programs.patagonian cypress Austrocedrus chilensis is vulnerable conifer native subantarctic South America, with high ecological importance economical potential.Its...
The study of plant responses to environmental stress factors is essential for management systems and anticipating their response climate change. main goal this was determine morphological physiological Nothofagus obliqua N. nervosa seedlings light temperature, two the acting in current natural distribution NW Patagonia. Responses were evaluated analyzing growth survival, as well traits related them, subjected three contrasting conditions (full-sun conditions, 50% sunlight 20% sunlight)...
Una estrategia de manejo forestal que podría combinar exitosamente la producción y conservación biodiversidad en bosques naturales, es su enriquecimiento con árboles nativos valor maderero. En ciertos Patagonia (e.g. matorrales) esto requiere definir el grado apertura inicial del dosel para garantizar éxito plantación. este trabajo, evaluamos efecto intensidad (IA) supervivencia crecimiento altura plantaciones especies forestales nativas maderables, tres sitios contrastantes (ladera sur: LS,...
Abstract The study of the genetic variation early height growth traits in seedlings helps to predict possible outcomes tree populations face climate change. Second‐year 10 geographically marginal Patagonian cypress ( Austrocedrus chilensis (D. Don) Pic. Ser. et Bizzarri) (Cupressaceae) was characterized under greenhouse conditions. Variation among and within an average 15 open‐pollinated families (comprising 21 per family) for each population analysed six size timing obtained from fitted...
In temperate mountainous regions, altitudinal clines in tree size and growth habit develop from a gradual adjustment of multiple traits to tolerate harshening conditions with altitude. We perform common garden trial seedlings two stands Nothofagus pumilio: low altitude, tall forest (1200 m a.s.l) vs. high shrubby (1560 a.s.l), determine whether the contrasting habits observed have genetic basis, which expresses juvenile life stage. Growth syndrome was assessed including size, phenology,...
The idea of a diagnostic species is an important concept in plant sociology. However, since over century ago, when the term “association” was introduced, identification has been among most controversial topics phytosociological practice. With aim promoting methodological standardization sociology, this paper addresses: 1) need to distinguish between concepts and methods involved definition syntaxa (analysing relevés, characterization, diagnosis, naming typification), 2) support improve...
This study was designed to examine relationships between climate and vegetation of the Pacific rim North America, from Mediterranean deserts California Alaska’s boreal taiga. Relations were inferred temperature rainfall data recorded at 457 weather stations by sampling around these stations. Climate used construct climatograms, calculate forty one variables detect main latitudinal longitudinal gradients. In order identify best functions able relate our variables, polynomial non-polynomial...
Water-use efficiency (WUE) is a physiological parameter that plays significant role in the evolutionary dynamics of many forest tree species. It can be estimated indirectly through carbon isotope discrimination (Δ). In general, plants more arid origins have lower values Δ. order to study degree genetic control this and variation Δ Patagonian Cypress seedlings, three Argentinean natural populations chosen represent two contrasting precipitation regimes were sampled common garden trial. The...
This report presents the first of two parts a bioclimatic classification vegetation United States. Using geographical information system, 987 weather stations were located along longitudinal macrotransect from shores Atlantic to Pacific on four maps: Map Physiographic Divisions Conterminous US, US Potential Natural Vegetation Map, Ecoregion and Terrestrial Ecosystems-Isobioclimates Based these maps, bibliographic resources field data, we deduced potential natural (PNV) each station; then,...
Multifunctional productive systems based on native species management, a new paradigm that counters colonial worldviews, offer sustainable sources of food and materials while preserving biodiversity. Despite extensive discussions in herbaceous agricultural systems, applying this concept to forests Northern Patagonia remains unclear. system implementation can be approached from fractal perspective, with evaluations at the stand level being essential for understanding ecological processes...
Abstract Global warming can pose a significant threat to forest tree species, particularly those inhabiting subalpine forests in temperate regions. Plasticity and adaptation are essential for the persistence of these forests. Nothofagus pumilio, dominant species at high-altitude limits Patagonian forests, is well adapted cold conditions. To assess its potential responses global warming, we established genetic multi-environment field trial across three altitudes, 1200 (the current optimal N....
Capsule Cases of mixed clutches in raptor nests are very scarce the literature. Among 279 harrier monitored between 1991–1996 and 2010–2011 two different areas central Spain, quail eggs were found one nest, 13 others contained partridge eggs. Harrier smaller which galliform eggs, therefore more similar size appearance to foreign may suggest a maladaptative behaviour on part galliforms.
This paper describes the vegetation of Carson Desert (Nevada, USA) based on a phytosociological analysis its major plant associations, as determined by Braun-Blanquet method. Diagnostic tables, climatic, edaphic, and biogeographical data were used to establish floristic affinities among identified communities interpret their distributions in zonal gradients. Their syntaxonomic positions classes Allenrolfeetea occidentalis Artemisio tridentatae–Juniperetea osteospermae, new class Sarcobatetea...
