Revisit the Medieval Warm Period and Little Ice Age in Proxy Records from Zemu Glacier Sediments, Eastern Himalaya: Vegetation and Climate Reconstruction

Quaternary, 2023
The Late Holocene fossil pollen records from the Zemu glacier, located in Yabuk, North Sikkim, in the eastern Himalayas, effectively generated quantitative climate reconstructions based on the transfer function model.

Unravelling the palaeobiogeographical history of the living fossil genus Rehderodendron (Styracaceae) with fossil and extant pollen and fruit data

BMC Ecology and Evolution, 2022
Background The relict genus Rehderodendron (Styracaceae), the species of which are restricted to mostly warm temperate to tropical climate in East Asia today, is known from fossil fruits and pollen in Europe during warmer periods from the lower Eocene to

The Eurasian Modern Pollen Database (EMPD), version 2 [PDF]

Earth System Science Data, 2020
The Eurasian (née European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples to help support studies of past climate, land cover, and land use using fossil pollen.

Spatial distribution of modern pollen and fungal spores and their ecological indication in Qinghai Lake on northeastern Tibetan Plateau, China

Ecological Indicators, 2022
The Qinghai-Tibet Plateau (QTP) – also called the “third pole” – is an ideal area to study the long-term relationship between people and the environment due to its sensitivity to both climate change and anthropogenic activities. Qinghai Lake in the north-

The modern pollen-vegetation relationship of a tropical forest-savannah mosaic landscape, Ghana, West Africa [PDF]

, 2017
Transitions between forest and savannah vegetation types in fossil pollen records are often poorly understood due to over-production by taxa such as Poaceae and a lack of modern pollen-vegetation studies.

Pollen morphology of extant Winteraceae: a study allowing SEM-based affiliation of its fossil representatives

Acta Palaeobotanica, 2017
When applying high-resolution microscopy, the pollen morphology of extant taxa can be used to classify fossil pollen, that is, to address the latter in the established systematic-phylogenetic framework.

Tiny pollen grains: first evidence of Saururaceae from the Late Cretaceous of western North America [PDF]

PeerJ, 2017
Background The Saururaceae, a very small family of Piperales comprising only six species in four genera, have a relatively scanty fossil record outside of Europe. The phylogenetic relationships of the four genera to each other are resolved, with the type

Iron Age to Medieval entomogamous vegetation and Rhinolophus hipposideros roost in south-eastern Wales (UK) [PDF]

, 2006
Karst cave systems are well developed in Wales (UK) and, in some instances, constitute important bat roosts. Ogof Draenen, near Blaenavon in south-east Wales, is the most recent major cave discovery (1994) with already > 70 km of passages explored ...

Eocene Loranthaceae pollen pushes back divergence ages for major splits in the family [PDF]

PeerJ, 2017
Background We revisit the palaeopalynological record of Loranthaceae, using pollen ornamentation to discriminate lineages and to test molecular dating estimates for the diversification of major lineages. Methods Fossil Loranthaceae pollen from the Eocene

Variability within the 10-year pollen rain of a seasonal neotropical forest and its implications for paleoenvironmental and phenological research. [PDF]

PLoS ONE, 2013
Tropical paleoecologists use a combination of mud-water interface and modern pollen rain samples (local samples of airborne pollen) to interpret compositional changes within fossil pollen records.
