The relationships between woody vegetation cover and fire, climate, herbivory, and human activities in African savanna ecosystems are complex. Fire has been managed by humans for thousands of years, but post 1800, fire suppression was implemented in many areas. The impact of these policies are largely unknown, due to a lack of long-term records extending from before, during and after their implementation

Turbiosphaera archangelskyi sp.nov. and a morphological complex from the late Middle to Late Eocene of southern high latitudes: Biostratigraphic, palaeoenvironmental and palaeoceanographic implications Rev. Palaeobot. Palynol. (IF 1.9) Pub Date : 2023-09-17 G. Raquel Guerstein, Cecilia R. Amenábar, Robert A. Fensome, Gloria Daners, Elbio D. Palma
We record a morphological complex of species of the dinoflagellate-cyst genus Turbiosphaera from the uppermost Río Turbio Formation, considered to of late Priabonian age, and from equivalent units of the Austral-Magallanes Basin, southern Argentina and southern Chile. Previously, specimens now assigned to Turbiosphaera archangelskyi sp. nov and Turbiosphaera sarrisii were assigned to the cosmopolitan

Atlas of Holocene pollen of Southern Italy (Mar Piccolo, Taranto) Rev. Palaeobot. Palynol. (IF 1.9) Pub Date : 2023-09-18 Gabriele Niccolini, Adele Bertini
There have been plenty of palynological studies on Quaternary from the Mediterranean region in the past decades. However, few focused on the iconographic documentation of pollen grains. An illustrated, descriptive atlas of pollen from Holocene sediments (S05B core and surface samples) and mosses from Mar Piccolo (southern Italy) was compiled. The pollen atlas includes 143 taxa representative of local

Approaches to pollen taxonomic harmonisation in Quaternary palynology Rev. Palaeobot. Palynol. (IF 1.9) Pub Date : 2023-09-16 H. John B. Birks, Kuber P. Bhatta, Vivian A. Felde, Suzette G.A. Flantua, Ondřej Mottl, Simon G. Haberle, Annika Herbert, Henry Hooghiemstra, Hilary H. Birks, John-Arvid Grytnes, Alistair W.R. Seddon
Pollen taxonomic harmonisation involves the standardisation of the nomenclature of pollen and fern spores with similar morphotypes at the determination level that is common to all grains or spores with that morphotype within the pollen sequence(s) of interest. Such harmonisation is required prior to subsequent investigations such as numerical analysis, comparing, mapping, synthesis, and environmental

Characterization of a pyritized fossil pollen cone from Clarkia, Idaho Rev. Palaeobot. Palynol. (IF 1.9) Pub Date : 2023-09-12 Rebecca N. DeKoster, William C. Rember, Victoria E. McCoy
The Miocene Lake deposit in Clarkia, Idaho is composed of highly fossiliferous silty clays. These rocks were formed in an anoxic and likely toxic deep lacustrine environment which facilitated the fossilization of plant material with a high amount of morphological detail. Many of the plant compression fossils exhibit exceptional preservation, including the preservation of original biomolecules. Pyritized

The potentials of accessory palynomorphs as sequence stratigraphic and basin evaluation tools in the shallow offshore Niger Delta Rev. Palaeobot. Palynol. (IF 1.9) Pub Date : 2023-09-09 P.A. Adeonipekun, M.A. Adeleye, M.B. Adebayo, M.A. Sowunmi
Freshwater algae – Botryococcus and Pediastrum, marine indices – dinoflagellates and microforaminiferal linings, and charred Poaceae cuticles are accessory palynomorphs commonly recovered from Niger Delta sediments. The abundant recovery of these non-pollen palynomorphs necessitates a test of their usefulness for sequence stratigraphic purposes. Bio-sequence stratigraphic data and stratigraphic distribution
