Miocene palynoflora from the KRAM-P 218 leaf assemblage from the Bełchatów Lignite Mine (Central Poland)

Acta Palaeobotanica, 2016
During a palynological analysis of four samples from the Bełchatów KRAM-P 218 collection of plant macroremains 95 fossil species of sporomorphs were identified. Among the non-pollen palynomorphs was the fossil species Desmidiaceaesporites cosmarioformis,

Island ecosystem responses to the Kuwae eruption and precipitation change over the last 1600 years, Efate, Vanuatu

Frontiers in Ecology and Evolution, 2023
IntroductionIslands of the Southwest Pacific are exposed to geologic and climate-related disturbances that occur on a range of timescales and which probably affect, to varying degrees, their terrestrial ecosystems.

Relationship of Surface Pollen with Climate and Vertical Vegetation Communities in Subtropical Mountainous in Southern China

Redai dili, 2022
Pollen analysis is one of the environmental proxies useful for quantitative reconstruction of paleoecology and paleoclimate, and the establishment of a quantitative relationship between surface pollen and vegetation is crucial for accurate interpretation

Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance [PDF]

, 2016
Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica,

Fungal spores in Caribbean mangrove sediments, dataset from southeastern Mexico

Data in Brief, 2023
Most paleoecological investigations use different biotic or abiotic proxies for climate and environmental reconstructions. Although fossil pollen is one of the most used biological proxies, Non-Pollen Palynomorphs (NPPs), especially fungal spores and ...
