Hotspots of biogeochemical activity linked to aridity and plant traits across global drylands
(Springer Nature, 2024-04-12)Perennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, ... -
Conservation value and ecosystem service provision of Nothofagus antarctica forests based on phenocluster categories
(Springer Nature, 2025-01-20)Traditional approaches of forest classifications were based on tree species composition, but recently combine phenology and climate to characterise functional (cyclic and seasonal greenness) rather than structural or ... -
Three levels of simple morphophysiological dormancy in seeds of Ilex (Aquifoliaceae) species from Argentina
(Cambridge University Press, 2018-05-25)As a contribution to understanding the world biogeography of seed dormancy in the cosmopolitan genus Ilex, we studied seeds of I. argentina, I. brasiliensis, I. brevicuspis, I. dumosa, I. paraguariensis and I. theezans ... -
Unforeseen plant phenotypic diversity in a dry and grazed world
(Springer Nature, 2024-08-22)Earth harbours an extraordinary plant phenotypic diversity1 that is at risk from ongoing global changes2,3. However, it remains unknown how increasing aridity and livestock grazing pressure—two major drivers of global ... -
Response of forage production to drought in silvopastoral systems in Argentina
(Springer Nature, 2024-10)An increase in the frequency and intensity of agricultural and ecological droughts is expected. This study aimed to assess the response of annual forage dry matter production (AFP) to drought in 22 sites across Argentina’s ... -
Changes derived by the silvopastoral management in Nothofagus antarctica forests of Tierra del Fuego compared to other productive environments
(Springer Nature, 2024-07-05)Silvopastoral systems (SPS) are suggested to promote a balance between productive alternatives and ecological values. The aim of this study was to determine the changes generated by SPS (thinning + livestock) in Nothofagus ... -
Fertilization, irrigation and pasture sown to improve herbage production and quality in Nothofagus antarctica silvopastoral systems in southern Patagonia.
(Springer Nature, 2024-10)Nothofagus antarctica forest extends from 46 to 56° south latitude and its main use has been as silvopastoral systems (SPS). Several studies have characterized understory of N. antarctica SPS. However, other practices like ... -
Current trends in silvopastoral systems
(Springer Nature, 2024-10-26)In Latin America, SPS are practiced in various ecosystems in humid and dry broadleaved forests, temperate forests, tropical and subtropical coniferous forests, and savannas. These ecosystems range from sea level up to> ... -
Evaluation of CBD and THC content in indoor-grown Cannabis sativa cv. MK 2021 flowers for medical use
(Ediciones INTA, 2024-11)Cannabis sativa L. has been widely used for medicinal purposes due to the content of specific molecules called cannabinoids. CBD (cannabidiol) is one of the most known cannabinoids for medicinal ends, showing a great ... -
Retention levels and years-after-harvesting influence over soil microbial activity and biomass in Southern Patagonian forests
(MDPI, 2024-11-20)Variable retention harvesting (VRH) was designed for timber purposes and biodiversity conservation in natural forests. This system was globally tested, but few studies are related to soil microbial components. The objective ... -
Change in functional trait diversity mediates the effects of nutrient addition on grassland stability
(British Ecological Society, 2024-09-02)1. Nutrient enrichment impacts grassland plant diversity such as species richness, functional trait composition and diversity, but whether and how these changes affect ecosystem stability in the face of increasing climate ... -
Stand characteristics, leaf traits and growth of threatened conifer Pilgerodendron uviferum (Cupressaceae) in Southern Patagonia, Argentina
(MDPI, 2024-10-18)Pilgerodendron uviferum is an endemic Cupressaceae of Patagonia (Argentina) that is restricted to a small group of individual trees, growing in isolated populations (relicts) along its distribution. The main objective was ... -
Widening global variability in grassland biomass since the 1980s
(Springer Nature, 2024-08-05)Global change is associated with variable shifts in the annual production of aboveground plant biomass, suggesting localized sensitivities with unclear causal origins. Combining remotely sensed normalized difference ... -
Dominance and rarity in tree communities across the globe: patterns, predictors and threats
(Wiley, 2024-07-17)Aim. Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation ... -
Experimental Exclusion of Guanaco Grazing Increases Cover, Diversity, Land Function and Plant Recruitment in Patagonia
(Tech Science Press, 2024-07-30)Semiarid Patagonia represents 25% of the rangeland area in Argentina, and sheep overgrazing has degraded about a third of it in the past. In this century, depleted domestic stocks have mostly stabilized, but Guanaco ... -
