code and data for "A SPATIAL BIRTH-DEATH PROCESS TO MODEL SESSILE ORGANISMS" by IanFlint Peter Vesk, Yan Wang and Aihua Xia

We introduce a spatial birth-death process with birth/death rates that explicitly depend on distances to other points. a model is developed that is useful for analysing the spatiotemporal dynamics of sessile organisms, such as trees. The model can be applied to forest dynamics plots. Field data (raw_qld_trees.rda) are from the following source, packaged here for easy analysis.

本研究提出一类空间生死过程模型，其生死速率显式依赖于与其他空间点的距离。该模型可用于分析树木等固着生物的时空动态特征，适用于森林动态样地的相关研究。本研究所用野外数据（raw_qld_trees.rda）源自下述来源，已在此处整理为便于分析的格式。若需复用该数据，请引用原始来源：Bradford, Matt; Murphy, Helen; Ford, Andrew; Hogan, Dominic; & Metcalfe, Dan (2014): 北昆士兰CSIRO永久性雨林样地. 第3版. CSIRO. 数据集. https://doi.org/10.4225/08/59475c67be7a4
