Effect of climate on traits of dominant and rare tree species in the world’s forests
(Springer Nature, 2025-05-22)Species’ traits and environmental conditions determine the abundance of tree species across the globe. The extent to which traits of dominant and rare tree species differ remains untested across a broad environmental range, ... -
Global impoverishment of natural vegetation revealed by dark diversity
(Springer Nature, 2025-05-23)Anthropogenic biodiversity decline threatens the functioning of ecosystems and the many benefits they provide to humanity1. As well as causing species losses in directly affected locations, human influence might also reduce ... -
Demography of Grazed Tussock Grass Populations in Patagonia
(Elsevier, 2005-09)The cover of Festuca gracillima (coirón fueguino), a native tussock grass that dominates grass steppes of Southern Patagonia and Tierra del Fuego, has diminished under continuous sheep grazing. This loss is a concern, ... -
Soil water dynamics, root systems, and plant responses in a semiarid grassland of Southern Patagonia
(Elsevier, 2014-05)Distribution of water enables different ecological niches and the coexistence of species. This separation may be in space: vertically in the soil profile or horizontally by lateral root exploration; and in time, as plants ... -
Interactions among nutrients govern the global grassland biomass–precipitation relationship
(National Academy of Sciences, 2025-04-11)Ecosystems are experiencing changing global patterns of mean annual precipitation (MAP) and enrichment with multiple nutrients that potentially colimit plant biomass production. In grasslands, mean aboveground plant biomass ... -
Frequent failure of nutrients to increase plant biomass supports the need for precision fertilization in agriculture
(Springer Nature, 2025-04-25)Implementing precision fertilization to maximize crop yield while minimizing economic and environmental impacts has become critical for agriculture. Variability in biomass response to fertilization within fields, among ... -
Respuesta al raleo en comparación con el autorraleo en bosques secundarios de Nothofagus pumilio y N. antarctica de la Patagonia Sur, Argentina.
(INFOR, 2025-04)El raleo planificado en bosques secundarios puede reducir el tiempo necesario para obtener los productos deseados para la industria. En 2006 se establecieron parcelas de monitoreo a largo plazo en dos rodales de la misma ... -
Forb diversity globally is harmed by nutrient enrichment but can be rescued by large mammalian herbivory
(Springer Nature, 2025-03-15)Forbs (“wildflowers”) are important contributors to grassland biodiversity but are vulnerable to environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad ... -
The global distribution and drivers of wood density and their impact on forest carbon stocks
(Springer Nature, 2024-12)The density of wood is a key indicator of the carbon investment strategies of trees, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls ... -
Interactive and unimodal relationships between plant biomass, abiotic factors, and plant diversity in global grasslands.
(Springer Nature, 2025-01-21)Grasslands cover approximately a third of the Earth’s land surface and account for about a third of terrestrial carbon storage. Yet, we lack strong predictive models of grassland plant biomass, the primary source of carbon ... -
Sequías agropecuarias en la provincia de Santa Cruz, Argentina, en el período 1996-2018
(Asociación Argentina de Ecología, 2024-12)Las sequías recurrentes afectan tanto a los ecosistemas naturales como a las actividades humanas. Generan daños económicos significativos, en especial cuando son prolongadas. El objetivo de este estudio es detectar y ... -
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 ... -
