Mycorrhizal symbioses and tree diversity in global forest communities
(American Association for the Advancement of Science., 2025-06-13)Unraveling the mechanisms underlying the maintenance of species diversity is a central pursuit in ecology. It has been hypothesized that ectomycorrhizal (EcM) in contrast to arbuscular mycorrhizal fungi can reduce tree ... -
Dominant species predict plant richness and biomass in global grasslands
(Springer Nature, 2025-06)The bidirectional relationship between plant species richness and community biomass is often variable and poorly resolved in natural grassland ecosystems, impeding progress in predicting impacts of environmental changes. ... -
Aridity modulates grassland biomass responses to combined drought and nutrient addition
(Springer Nature, 2025-05-19)Plant biomass tends to increase under nutrient addition and decrease under drought. Biotic and abiotic factors influence responses to both, making the combined impact of nutrient addition and drought difficult to predict. ... -
Is there a relationship between the concentration of nutrients in leaves and the class of site where Nothofagus antarctica forests growth in southern Patagonia, Argentina? = ¿Existe relación entre la concentración de nutrientes en hojas con la clase sitio donde se desarrollan los bosques de Nothofagus antarctica en Patagonia sur, Argentina?
(Universidad Austral de Chile, 2025-06)The objective of this study was to determine whether differences in site quality correlate with better leaf nutritional status in pure Nothofagus antarctica (ñire) forests. Nine pure ñire stands of the three site classes ... -
The global spectrum of tree crown architecture
(Springer Nature, 2025-05-26)Trees can differ enormously in their crown architectural traits, such as the scaling relationships between tree height, crown width and stem diameter. Yet despite the importance of crown architecture in shaping the structure ... -
Experiencia de pastoreo ovino de pasturas de gramíneas introducidas en Patagonia Austral, Argentina = Experience of sheep grazing on introduced grass pastures in Southern Patagonia, Argentina = Experiência com pastoreio de ovelhas em pastagens de gramíneas introduzidas na Patagônia Sul, Argentina
(Universidad Cooperativa de Colombia, 2025-05)Introducción: la ganadería ovina en Patagonia Austral se sustenta en el aprovechamiento extensivo de los pastizales naturales en un escenario donde la productividad del pastizal acompaña la variabilidad de las condiciones ... -
Local nutrient addition drives plant biodiversity losses but not biotic homogenization in global grasslands
(Springer Nature, 2025-05-27)Nutrient enrichment typically causes local plant diversity declines. A common but untested expectation is that nutrient enrichment also reduces variation in nutrient conditions among localities and selects for a smaller ... -
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
