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

Cladistics, Volume 42, Issue 4, Page 401-412, August 2026.
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 ...

Paleogeography

, 2015
A paleogeographic understanding of the genesis of a landscape in time and space is needed to collect and understand data for sea-level reconstruction. So-called sea-level index points can be derived from numerous sedimentary environments, but what is their indicative meaning and value?

Contrasting Palaeogeographic Histories but Similar Microevolutionary Responses in Low‐Dispersal Island Grasshoppers From Two Mediterranean Archipelagos

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Island archipelagos serve as natural laboratories for understanding how geological history, climate change and dispersal limitation interact to shape diversification. Here, we examine how these forces influence patterns of genomic divergence, demographic dynamics and phenotypic variation in island‐endemic taxa, with a particular focus on ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, Volume 73, Issue 5, Page 1631-1663, August 2026.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Enhanced Orbital‐Forcing Sensitivity of Northern High Latitude Temperatures in the Late Cretaceous Relative to Modern Geography

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Orbital forcing is a primary driver of paleoclimate change, but its influence on deep time climates, particularly in the polar regions of the Late Cretaceous, is poorly understood. Here, we conduct climate simulations with an atmosphere‐ocean‐vegetation coupled model, MIROC4mV, to investigate the response of northern high latitude temperature ...

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...

Buried and Massive Ground Ice on the West Coast of Baidaratskaya Bay in the Kara Sea

Лëд и снег, 2015
Using data on the structure, conditions of occurrence (bedding), and the isotope composition of massive ice beds on the West coast of Baydaratskaya Bay it was established that the massive ice beds even occurring in the same outcrop may be related to ...

Insights into the Cenozoic geology of North Beirut (harbour area): biostratigraphy, sedimentology and structural history

UCL Open Environment, 2020
The biostratigraphy and sedimentology of the outcrops and bedrock recently exposed in archaeological excavations around the harbour area of Beirut (~5 km²) unlock the geological and structural history of that area, which in turn are key to understanding
