High Contagiousness and Rapid Spread of Severe Acute Respiratory Syndrome Coronavirus 2
Severe acute respiratory syndrome coronavirus 2 is the causative agent of the ongoing coronavirus disease pandemic. Initial estimates of the early dynamics of the outbreak in Wuhan, China, suggested a doubling time of the number of infected persons of 6–7 days and a basic reproductive number (R 0 ) of 2.2–2.7. We collected extensive individual case reports across China and estimated key epidemiologic parameters, including the incubation period (4…
Mechanisms of a coniferous woodland persistence under drought and heat
Predictions of warmer droughts causing increasing forest mortality are becoming abundant, yet few studies have investigated the mechanisms of forest persistence. To examine the resistance of forests to warmer droughts, we used a five-year precipitation reduction (45% removal), heat (+4 C above ambient) and combined drought and heat experiment in an isolated stand of mature Pinus edulis-Juniperus monosperma. Despite severe experimental drought and…
Who is the new sheriff in town regulating boreal forest growth
Climate change appears to be altering boreal forests. One recently observed symptom of these changes has been an apparent weakening of the positive relationship between high-latitude boreal tree growth and temperature at some sites (D'Arrigo et al 2008). This phenomenon is referred to as the 'divergence problem' or 'divergence effect' and is thought to reflect a non-linear relationship between temperature and tree growth, where recent warming has…
Ecological footprint and biological capacity time series assessment for a forest region in northeastern China
Anthropogenic disturbances have caused major landscape changes in the forests of northeastern China during the past 50 years. In particular, continuous over-deforestation has greatly decreased the region's forest quality. Ecological footprint analysis generates aggregated information about a population's demand on nature and the population regional biological capacity. To show the forest change and the population's ecological demand on the study …
Key natural impacting factors of China’s human population distribution
Temporal and spatial assessment of natural resource use in China using ecological footprint method
China has about 20% of the world's population. With rapid economic development and substantial population increase, China is now faced with severe conflicts between limited natural resources and increasing resource requirements. In this study, we used the ecological footprint method to assess the resource demand and supply conditions of each land use in China between 1978 and 2003. In order to provide insight into the spatial heterogeneity of res…
