Physical and environmental drivers of Paleozoic tetrapod dispersal across Pangaea

Nature Communications, 2018
The late Paleozoic was a time of major transition for tetrapods. Here, Brocklehurst and colleagues analyse the biogeography of Paleozoic tetrapods and find shifts in dispersal and vicariance associated with Carboniferous mountain formation and end ...

A new paleozoic Symmoriiformes (Chondrichthyes) from the late Carboniferous of Kansas (USA) and cladistic analysis of early chondrichthyans.

PLoS ONE, 2011
BackgroundThe relationships of cartilaginous fishes are discussed in the light of well preserved three-dimensional Paleozoic specimens. There is no consensus to date on the interrelationship of Paleozoic chondrichthyans, although three main phylogenetic ...

State‐Dependence of Polar Amplification in an Idealized GCM

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Polar amplification (PA) is a robust feature of contemporary climate change, but its state‐dependence across different climate conditions is poorly understood despite potential relevance to paleoclimate records and future projections. Here we examine the state‐dependence of PA across a wide range of climate states in an idealized moist general

Halogenated Organic Compounds: A Massive Halogen Reservoir and an Intriguing Component of the Marine Dissolved Organic Matter Pool

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Biogeochemical reactions produce volatile halocarbons and semi‐ to nonvolatile dissolved organic halogens (DOX) in marine systems. The former has a large influence on atmospheric chemistry, but little is known about DOX. Here, we present depth profiles of dissolved organic bromine (DOBr) and ‐iodine (DOI) isolated from the Central North ...

Geochemical characteristics and genesis of the Paleozoic natural gas in the southern Ordos Basin, China

Journal of Natural Gas Geoscience
The geochemical characteristics of the Paleozoic natural gas in the southern part of the Ordos Basin shows significant differences from those in the northern part. These differences lead to the increase in dryness coefficient and a heavier carbon isotope

Dynamic Downscaling Resolution Affects Hot Extreme Processes: A Case Study of 2013 Summer Extreme Hot Event Over Central and Eastern China

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Understanding the complex thermal and dynamic processes during extreme climate event is important. This study investigated the 2013 extreme hot event (EHE) in central and eastern China using Weather Research and Forecasting model with resolution of 25 and 9 km (WRF25 and WRF9) respectively.

Correlated Modes of Spatiotemporal Variations Between Biomass Burning Aerosols and Tropospheric Temperature Over the Indian Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Biomass burning aerosols influence atmospheric temperatures by absorbing solar radiation, thereby altering the contrast between day and night temperatures. This study investigates the correlation between these aerosols and day‐night (D‐N) temperature changes over India by applying principal component analysis (PCA) in long‐term (2003–2021 ...
