Modern pollen spectra from Costa Rica

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 pلramo. 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.
