Holocene changes in the conditions of sedimentation in the eastern part of Lake Jamno based on sediment profile JS-64

open access: yesLimnological Review, 2015
Changes in sedimentological conditions in Lake Jamno during its development throughout the Holocene are presented in this paper. For this purpose, selected granulometric and geochemical parameters were used, which describe the nature and dynamics of the ...

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

MULTI-ARCHIVE TEMPERATURE RECONSTRUCTION OF THE RUSSIAN ARCTIC FOR THE PAST TWO MILLENNIA

open access: yesGeography, Environment, Sustainability, 2014
We present a multi-archival mean annual quantitative temperature reconstruction for Northeastern Europe covering the period of the past two millennia based on tree-ring, pollen, and historical data. This reconstruction was developed primarily to build up

High‐frequency sequences within a retrogradational deltaic succession: Upper Cenomanian Dunvegan Formation, Western Canada Foreland Basin

open access: yesThe Depositional Record, 2020
After prograding for several hundred kilometres during Middle Cenomanian time, the Dunvegan delta complex in north‐west Alberta and adjacent British Columbia experienced stepwise transgression, commencing at about the Middle to Late Cenomanian boundary ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Neogene history of fluvial to shallow marine successions in the Kendari Basin, SE Sulawesi, Indonesia

open access: yesThe Depositional Record, 2023
Collision between Australia and SE Asia began in Sulawesi, the world's eleventh‐largest island, in the Early Miocene and subsequently Neogene sediments were deposited largely in coastal to shelf environments throughout the island.

Rethinking areas of endemism and barriers: perspectives for a causal historical biogeography and a critique of Schultz and Cracraft (2024)

open access: yesCladistics, EarlyView.
Abstract Historical biogeography faces a persistent conceptual and methodological dilemma concerning the nature of its central analytical units. Using the recent proposal by Schultz and Cracraft (Cladistics 40, 653) as a catalyst, this article critiques the argument that causal inference necessitates the replacement of areas of endemism with barriers ...

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Observations on Palaeogeographical Evolution of Akrotiri Salt Lake, Lemesos, Cyprus

open access: yesGeosciences, 2021
Akrotiri Salt Lake is located 5 km west of the city of Lemesos in the southernmost part of the island of Cyprus. The evolution of the Akrotiri Salt Lake is of great scientific interest, occurring during the Holocene when eustatic and isostatic movements ...
