High Contagiousness and Rapid Spread of Severe Acute Respiratory Syndrome Coronavirus 2
TLDR
It is shown that active surveillance, contact tracing, quarantine, and early strong social distancing efforts are needed to stop transmission of the virus.
Uncertainties in the response of a forest landscape to global climatic change
Many studies have been conducted to quantify the possible ecosystem/landscape response to the anticipated global warming. However, there is a large amount of uncertainty in the future climate
Empirical and process-based approaches to climate-induced forest mortality models
TLDR
At issue is whether increasing modelcomplexity will improve prediction of future mortality, which is influenced in part by the modeling approach employed and two endpoints on a theoretical continuum of approach to mechanism are process-based andempirical model types.
Uncertainty and sensitivity analysis for models with correlated parameters
TLDR
A regression-based method is proposed to quantitatively decompose the total uncertainty in model output into partial variances contributed by the correlated variations andpartial variances contributing by the uncorrelated variations.
Toward a Mechanistic Modeling of Nitrogen Limitation on Vegetation Dynamics
TLDR
This is the first model of complete nitrogen allocation that simultaneously considers nitrogen allocation to light capture, electron transport, carboxylation, respiration and storage, and the responses of each to altered environmental conditions.
The Community Land Model Version 5: Description of New Features, Benchmarking, and Impact of Forcing Uncertainty
Author(s): Lawrence, DM; Fisher, RA; Koven, CD; Oleson, KW; Swenson, SC; Bonan, G; Collier, N; Ghimire, B; van Kampenhout, L; Kennedy, D; Kluzek, E; Lawrence, PJ; Li, F; Li, H; Lombardozzi, D; Riley,
A multi-species synthesis of physiological mechanisms in drought-induced tree mortality
TLDR
It is shown that, across multiple tree species, loss of xylem conductivity above 60% is associated with mortality, while carbon starvation is not universal, indicating that evidence supporting carbon starvation was not universal.
Global sensitivity analysis in hydrological modeling: Review of concepts, methods, theoretical framework, and applications
TLDR
A comprehensive review of global SA methods in the field of hydrological modeling, including the relationship between parameter identification, uncertainty analysis, and optimization in hydrology, and how to deal with correlated parameters, and time-varying SA is provided.
The Novel Coronavirus, 2019-nCoV, is Highly Contagious and More Infectious Than Initially Estimated
TLDR
The novel coronavirus (2019-nCoV) is a recently emerged human pathogen that has spread widely since January 2020 and it is estimated that the number of infected individuals during early epidemic double every 2.4 days, and the R0 value is likely to be between 4.7 and 6.6.
Taking off the training wheels: the properties of a dynamic vegetation model without climate envelopes, CLM4.5(ED)
Abstract. We describe an implementation of the Ecosystem Demography (ED) concept in the Community Land Model. The structure of CLM(ED) and the physiological and structural modifications applied to
