Vegetation change inferred from the pollen record in recent sediments from around the Lagos-East coastal environment (SW Nigeria)

Acta Palaeobotanica, 2019
Recent sediments from the coastal environment of Lagos East, Nigeria, were used to make a palynological reconstruction of the vegetation of the study area and to draw inferences about its palaeoclimate.

Evidence of the oldest extant vascular plant (horsetails) from the Indian Cenozoic

Plant Diversity, 2023
Equisetum (Equisetaceae) has long been a focus of attention for botanists and palaeontologists because, given its extensive and well-documented fossil record, it is considered the oldest extant vascular plant and a key element in understanding vascular ...

Holocene vegetation, climate and fire dynamics in the Serra dos Órgãos, Rio de Janeiro State, southeastern Brazil

Acta Palaeobotanica, 2020
We analysed pollen and macro-charcoal from a sediment core representing the last 9840 cal yr BP, collected at 2003 m a.s.l. in a patch of upper montane Atlantic Rain Forest (UMARF) embedded in a campos de altitude (high-elevation grassland) matrix in the

Vegetation responses to past volcanic disturbances at the Araucaria araucana forest‐steppe ecotone in northern Patagonia

Ecology and Evolution, 2022
Volcanic eruptions play an important role in vegetation dynamics and its historical range of variability. However, large events are infrequent and eruptions with a significant imprint in today's vegetation occurred far in the past, limiting our ...

The middle to late Eocene greenhouse climate modelled using the CESM 1.0.5 [PDF]

Climate of the Past, 2020
The early and late Eocene have both been the subject of many modelling studies, but few have focused on the middle Eocene. The latter still holds many challenges for climate modellers but is also key to understanding the events leading towards the ...
