The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR critical for accurate valuation effective conservation biodiversity. Using ground-sourced data from 777,126 permanent plots, spanning 44 countries most terrestrial biomes, we reveal a globally consistent positive concave-down BPR, showing that continued biodiversity loss would result in an accelerating decline forest...
Abstract Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land use and climate have considerably reduced the scale of this system 1 . Remote-sensing estimates to quantify losses from global forests 2–5 characterized by considerable uncertainty we lack comprehensive ground-sourced evaluation benchmark these estimates. Here combine several 6 satellite-derived approaches 2,7,8 evaluate forest potential outside agricultural urban lands. Despite regional variation,...
Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting spread invasive species1,2. Tree in particular have been relatively overlooked, even though they potential to transform economies3,4. Here, leveraging global tree databases5-7, we explore how phylogenetic functional diversity communities, human pressure environment influence establishment species subsequent invasion severity. We find that anthropogenic factors are key predicting...
Abstract 1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating increase in ecosystem productivity. Yet, this relationship varies substantially across environments, typically becoming less pronounced at high levels richness. However, alone cannot reflect all properties a community, including community evenness, which may mediate the between biodiversity and If evenness correlates negatively forests globally, then greater number not...
Abstract Understanding what controls global leaf type variation in trees is crucial for comprehending their role terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our understanding of the factors influencing forest types remains incomplete, leaving us uncertain about proportions needle-leaved, broadleaved, evergreen deciduous trees. To address these gaps, we conducted a global, ground-sourced assessment leaf-type by integrating inventory data with comprehensive form...
The emergence of alternative stable states in forest systems has significant implications for the functioning and structure terrestrial biosphere, yet empirical evidence remains scarce. Here, we combine global biodiversity observations simulations to test presence evergreen deciduous types. We reveal a bimodal distribution leaf types across temperate regions Northern Hemisphere that cannot be explained by environment alone, suggesting signatures states. Moreover, empirically demonstrate...
Abstract The density of wood is a key indicator the carbon investment strategies trees, impacting productivity and storage. Despite its importance, global variation in environmental controls remain poorly understood, preventing accurate predictions forest stocks. Here we analyse information from 1.1 million inventory plots alongside data 10,703 tree species to create spatially explicit understanding distribution drivers. Our findings reveal pronounced latitudinal gradient, with tropical...
Abstract Aim Ecological and anthropogenic factors shift the abundances of dominant rare tree species within local forest communities, thus affecting composition ecosystem functioning. To inform conservation management it is important to understand drivers dominance rarity in communities. We answer following research questions: (1) What are patterns communities? (2) Which ecological predict these patterns? And (3) what extinction risk locally species? Location Global. Time period 1990–2017....
Mixture tuned matched filtering (MTMF) image classification capitalizes on the increasing spectral and spatial resolutions of available hyperspectral data to identify presence, potentially abundance, a given cover type or endmember. Previous studies using MTMF have relied extensive user input obtain reliable classification. In this study, we expand traditional by selection supervised learning algorithms with rigorous cross-validation. Our approach removes need for subjective finalize...
Abstract Quantification of small stream contributions to global carbon cycling is key understanding how freshwater systems transmit and transform between terrestrial atmospheric pools. To date, greenhouse gas emissions dioxide methane from freshwaters, particularly in mountainous regions, remain poorly characterized due a lack direct field observations. Using unique longitudinal approach, we conducted surveys across two ecoregions (Middle Rockies Great Plains) the Clear Creek watershed,...
Abstract Using a concept proposed by Stehman and Czaplewski (1997), we implemented spatially-explicit Monte Carlo simulations to test the effects of manually introduced horizontal positional error on standard inter-rater statistics derived from twelve classified high-resolution images. Through found that both overall kappa accuracies decrease markedly with increasing distance, varying greatly across distances relevant practical application. The use ground reference sites falling solely in...
Abstract Palm oil accounts for approximately 50% of global vegetable production, and trends in consumption have driven large-scale expansion palm ( Elaeis guineensis ) plantations Southeast Asia. This has led to deforestation other socio-environmental concerns that challenge consumer goods companies meet no sustainability commitments. In support these commitments supply chain traceability, we seek improve on the current industry standard sourcing model ascribing social environmental risks...
Patterns of structural change associated with monodominant tropical forest complexes have remained enigmatic for decades. Here, we extend previous efforts in presenting a longitudinal, local-scale analysis dynamics central Africa. Using four 10-ha census plots measured across three time periods (959,312 stems ≥1 cm DBH), analyzed changes number biometrical attributes distinct types capturing the developmental gradient from mixed species to Gilbertiodendron dewevrei-dominated forest. We...
Palm oil production has been identified as one of the major drivers deforestation for tropical countries. To meet supply chain objectives, commodity producers and other stakeholders need timely information land cover dynamics in their shed. However, such data are difficult to obtain from suppliers who may lack digital geographic representations sheds locations. Here we present a "community model," machine learning model trained on pooled sourced many different stakeholders, develop specific...
Informed consent is a foundational concept in modern medicine. Despite physicians' ethical and legal obligations to obtain informed consent, no standard curriculum exists teach residents relevant knowledge skills. This paper presents qualitative study of at one academic medical center. The authors conducted focus groups with trainees the Departments Internal Medicine, Emergency Ob/Gyn analyzed their responses using rigorous methods. Four themes emerged: First, participants agreed that...
