Current and future projected climate suitability for seven invasive tropical plant species in the Wet Tropics. (NERP TE 7.2, CSIRO, source: CliMond, CSIRO)

This dataset shows the projected current and future (2070) climatic suitability for the invasive plant species Clidemia hirta, Hiptage benghalensis, Miconia calvescen, Miconia nervosa, Miconia racemose, Stevia ovata,and Turbina corymbosa across North Queensland. Modelled using CLIMEX.Method:CLIMEX (Sutherst & Maywald 1985; Sutherst et al. 2007) is a modelling package that enables users to model the climatic potential distribution of organisms based primarily on their current distribution, through taking into consideration climate response information from other knowledge domains if this is available.CLIMEX is a dynamic model that integrates the weekly responses of a population to climate using a series of annual indices. CLIMEX uses an annual growth index (GIA) to describe the potential for population growth as a function of soil moisture and temperature during favourable conditions, and up to eight stress indices (cold, wet, hot, dry, cold-wet, cold-dry, hot-wet and hot-dry) to determine the probability that the population can survive unfavourable conditions. The growth and stress indices are calculated weekly and are then combined into an overall annual index of climatic suitability, the Ecoclimatic Index (EI), which gives an overall measure of the potential of a given location to support a permanent population of the species. The Ecoclimatic Index (EI), ranges from 0 for locations at which the species is not able to persist to 100 for locations that are optimal for the species year round.CLIMEX is a bioclimatic model, relying on a database of climatic variables of long-term monthly precipitation totals, averages of minimum and maximum temperatures, and averages of relative humidity at 09:00 and 15:00 hours. The historical climate dataset used for these analyses was the CliMond dataset (www.climond.org), with a spatial resolution of 10’, using station records centred on 1975 (Kriticos et al. 2012).The impacts of climate change on the potential for each species to grow or pose an invasion risk were explored using a climate scenario model for 2070 taken from the CliMond dataset (Kriticos et al. 2012). The selected climate datasets were developed using the A1B emission scenario applied to the CSIRO Mk 3.0 global climate model. For each species, we used parameter sets that were either published or which we have developed.The CLIMEX parameters used in the model for Clidemia hirta are published in:Breadon R. C., Brooks S. J. & Murphy H. T. (2012) Biology of Australian Weeds: Clidemia hirta L.D.Don.

本数据集展示了北昆士兰地区7种入侵植物物种的当前及未来（2070年）气候适宜性分布预测，涉及物种包括：*Clidemia hirta*、*Hiptage benghalensis*、*Miconia calvescens*、*Miconia nervosa*、*Miconia racemosa*、*Stevia ovata*及*Turbina corymbosa*。本研究采用CLIMEX模型进行建模。

模型说明：CLIMEX（Sutherst & Maywald, 1985；Sutherst等, 2007）是一款生物气候建模工具包，其核心原理为以物种当前分布为基础，结合已有其他领域的气候响应相关研究数据，模拟物种的气候潜在分布范围。CLIMEX属于动态模型，通过一系列年度指标整合种群对气候的周度响应。该模型使用年度生长指数（GIA, Annual Growth Index）描述适宜条件下，由土壤湿度与温度共同决定的种群生长潜力；同时最多可引入8类胁迫指数（低温、高湿、高温、干旱、低温高湿、低温干旱、高温高湿、高温干旱），用于评估种群在逆境条件下的存活概率。生长指数与胁迫指数均通过周度计算后，整合得到综合年度气候适宜性指标——生态气候指数（EI, Ecoclimatic Index），该指数可量化某一区域对该物种永久种群的承载潜力。生态气候指数（EI）的取值范围为0~100：0代表该区域无法支撑该物种存续，100则代表该区域全年均为物种生存的最优生境。

CLIMEX属于生物气候模型，其所需的气候变量数据集包含长期月降水量总和、最低/最高气温平均值，以及每日09:00与15:00的相对湿度平均值。本分析使用的历史气候数据集为CliMond数据集（www.climond.org），空间分辨率为10弧分，数据以1975年为基准年份（Kriticos等, 2012）。

本研究基于CliMond数据集（Kriticos等, 2012）中的2070年气候情景模型，探讨气候变化对各物种生长潜力及入侵风险的影响。所选气候数据集基于A1B排放情景，耦合CSIRO Mk 3.0全球气候模型生成。针对各物种，本研究使用已公开或自研的CLIMEX参数集。
