Predicted disappearance of Cephalantheropsis obcordata in Luofu Mountain due to changes in rainfall patterns. [PDF]
PLoS ONE, 2012 BACKGROUND: In the past century, the global average temperature has increased by approximately 0.74°C and extreme weather events have become prevalent. Recent studies have shown that species have shifted from high-elevation areas to low ones because the ...

Simulation of population’s reproductive behaviour patterns within an agent-oriented regional model [PDF]
, 2015 The study focuses on the research on how the unevenness of demographic transition affects the social and demographic characteristics and their dynamics of a region’s population. The research was conducted by means of computerized experiments (simulations)

Snow tussocks, chaos, and the evolution of mast seeding [PDF]
, 2002 One hitherto intractable problem in studying mast seeding (synchronous intermittent heavy flowering by a population of perennial plants) is determining the relative roles of weather, plant reserves, and evolutionary selective pressures such as predator ...

Simulating the Reproductive Behavior of a Region’s Population with an Agent-Based Model
Economy of Region, 2015 The research analyses the impact of the inequality of demographic transition on socio-demographic characteristics of the regional population and on the dynamics of these characteristics. The study was conducted with the help of computer-based experiments (simulations), which was run on the original agent-based model. The model is an artificial society,
