Cong's paper on a new vegetation index is published in Remote Sensing of Environment. Congrats, Cong! Wang C, Chen J, Wu J, Tang Y, Shi P, Black A, Zhu K (2017). A snow-free vegetation index for improved monitoring of vegetation spring green-up date in deciduous ecosystems. Remote Sensing of Environment, 196, 1-12.
Dr. Cong Wang, recently graduated from Beijing Normal University, joins Zhu Lab in March 2017. Cong's PhD research focused on developing new algorithms for improving the monitoring of vegetation phenology using remote sensing and investigating the relationship between vegetation phenology and climate change. Cong brings in expertise in remote sensing to the lab. Welcome, Cong!
Cover image: Pictured is grassland at the Jasper Ridge Biological Preserve in California. Over 17 years, Kai Zhu et al. subjected this grassland to changes in temperature, precipitation, carbon dioxide, and nitrogen, both individually and in combination, to determine how simultaneous changes in multiple global environmental factors would affect primary production. Primary production was a ridge-shaped function of temperature and precipitation, with peak production increasing with added nitrogen and shifting to lower temperatures with added [...]

Greetings from Houston! I am now a Huxley Faculty Fellow in Department of BioSciences at Rice University. Biology began at Rice in 1912 with the appointment of Julian Huxley as the biology professor. Julian Huxley was the grandson of Thomas H. Huxley, a biologist himself and champion of Charles Darwin. Julian made many important contributions to the fields of ethology, ecology and cancer research, and was a powerful proponent of neo-Darwinism. His efforts are commemorated by [...]
Zhu K., Woodall C.W., Monteiro J.V.D., Clark J.S. (2015). Prevalence and strength of density-dependent tree recruitment. Ecology. 96, 2319-2327. My new paper on density dependence, as the cover paper in the cover of September 2015 issue of Ecology.
Is global change real? How about this year's temperature record? I helped to calculate the odds--really low, indeed! GO FIGURE: Figuring the odds of Earth's global hot streak The global heat streak of the 21st century can be explained with statistics that defy astronomical odds. First, the National Oceanic Atmospheric Administration calculates global average temperature going back to 1880. That's 135 years. So if no other forces were in play and temperatures last year were totally [...]
Zhiyuan Song and I got a seed grant from Center for Innovation in Global Health Ebola Innovation at Stanford. We will use our expertise to solve global health challenges. Abstract below. Dynamically evaluating and mapping Ebola outbreak risks in West and Central Africa in response to social-environmental changes Since the first recorded outbreak of human Ebola virus disease in 1976, the Ebola epidemics have evolved from rare smallscale endemics to frequent largerscale epidemics. The current ongoing [...]
