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...
Direct seeding of native species is a practice with high potential for the restoration degraded areas. Since availability seeds often limited, it necessary to make most this resource. In work, we tested two different technologies direct Festuca pallescens : seed coating and hydrogel soil amendment. For this, conducted greenhouse trials under controlled conditions five field sowing in environments that differ mean annual precipitation seasons (autumn spring). The consisted (1) natural...
Sensitivity to water availability is a key physiological trait for grassland species located in arid and semiarid environments, where successful germination closely related rainfall dynamics. Festuca pallescens inhabits diverse environments along steep precipitation gradient North Patagonia, thus offering suitable model the study of behavior response availability. By analyzing nine populations using hydrotime approach, we aimed find within-species variation. Seed population was analyzed...
Geographic patterns of variation in life-history traits have puzzled researchers for decades. However, the widely accepted idea that mating systems exhibit a tropical–temperate latitudinal trend, with extra-pair being norm among temperate species and genetic monogamy tropical species, is supported by sparse data, particularly birds breeding tropics even more so breed southern hemisphere zone. Our objective was to examine system Chilean Swallows (Tachycineta meyeni) at 54°S Tierra del Fuego,...
Abstract Background and Aims Grasses of the Festuca genus have complex phylogenetic relations due to morphological similarities among species interspecific hybridization processes. Within Patagonian fescues, information concerning relationships is very scarce. In pallescens, a widely distributed species, high phenotypic variability occurrence preclude clear identification populations. Given relevance natural rangelands for livestock production their degradation climate change, conservation...
In Patagonia, arid and semiarid lands are being affected both by inappropriate management practices, which leading to degradation, volcanic activity, whose effects still unclear. This study aimed test whether superficial deposition of tephra could benefit two the most prominent Patagonian forage grass species (Poa ligularis Pappostipa speciosa var. speciosa). Pots with P. were kept under wet (W) dry (D) conditions in presence (T+) or absence (T−) for 105 days, then all well-watered. We...
El género Tachycineta incluye nueve especies de golondrinas distribuidas a lo largo América con grandes diferencias en su sistema apareamiento genético y sus tasas paternidad extra-pareja. En un estudio previo se encontró que 78% los nidos la Golondrina Ceja Blanca (Tachycineta leucorrhoa) pueden tener al menos pichón extra-pareja, una variación entre 1–4 padres distintos pichones esas nidadas. Como extra-pareja puede ser indicador intensidad selección sexual, este trabajo evalúa el...
