我们分析了保存在表层湖泊、沼泽沉积物和土壤中的花粉光谱，以提供哥斯达黎加一系列植被类型的现代花粉雨信息。我们在29个地点收集了10种主要植被类型的样本：红树林、热带干林、衍生稀树草原、热带湿林、热带湿林、低地淡水沼泽、山地雨林、山地雨林、山地沼泽和páramo。相似植被样地的花粉组合一般相似，在非趋势对应分析中聚类在一起。结果表明，哥斯达黎加主要植被类型具有明显的花粉谱。
We analyzed pollen spectra preserved in surface lake and mire sediments and soils to provide information on modern pollen rain across a range of vegetation types in Costa Rica. We collected samples at 29 sites located within ten principal vegetation types: mangrove, tropical dry forest, derived savanna, tropical moist forest, tropical wet forest, lowland freshwater swamp, premontane rain forest, montane rain forest, montane bog, and páramo. Samples from sites with similar vegetation generally had similar pollen assemblages and clustered together in detrended correspondence analysis. Results indicate that major vegetation types in Costa Rica have distinct pollen spectra.
