Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Aptian/Albian (Early Cretaceous) paleogeography of the South Atlantic: a paleontological perspective

, 2014
Paleontological data obtained in recent years reinforce the hypothesis that Aptian marine sedimentation in the sedimentary basins of the Brazilian continental margin - except the Pelotas basin, the southernmost Brazilian basin - took place under the ...

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

Journal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

High β‐diversity in fig wasp communities driven by species turnover in widely distributed Neotropical fig trees

Oikos, EarlyView.
Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27
