The distribution of non-pollen palynomorphs (NPP) in a core from Cook's Bay, Lake Simcoe, Ontario, Canada shows a response to changes in water quality accompanying agriculture, urbanization, and industrialization. Low concentrations of nutrients in sediments with little non-arboreal pollen (NAP) record low disturbance prior to European settlement around the 1850s. These sediments are rich in desmi ...

- ... The statistical analysis of published Paleocene-Late Miocene palynological data from Patagonia supports several major stages of vegetation. These stages represent distinctive floral assemblages, both in composition and structure. Detrended correspondence analysis shows that during the Paleocene, southern South America was dominated by Australasian, Neotropical and Pantropical phytogeographical ele ...
