Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Paleomagnetic Study of Mesozoic Continental Sediments Along the Northern Tien Shan (China) and Heterogeneous Strain in Central Asia [PDF]

, 1991
A paleomagnetic study of rocks from the northern foot of the Tien Shan and the southern border of the Dzungar Basin, east of Urumqi (44.2°N, 86.0°E), spanning ages from middle Jurassic to early Tertiary was carried out to constrain the tectonic evolution

Characterization of the Wild Trees and Shrubs in the Fergana Valley: Diversity and Distribution, Threats

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The content of this paper is significant because it presents the first comprehensive assessment of the dendroflora of the Fergana Valley, contributes to understanding species richness across biogeographic regions, and places the results in the context of Central Asian flora and global biodiversity studies.

THERMAL HISTORY OF THE GULI PLUTON (NORTH OF THE SIBERIAN PLATFORM) ACCORDING TO APATITE FISSION-TRACK DATING AND COMPUTER MODELING

Геодинамика и тектонофизика, 2020
We present the first results of fission-track dating of apatite monofractions from two rock samples taken from the Southern carbonatite massif of the world’s largest alkaline ultrabasic Guli pluton (~250 Ma), located within the Maymecha-Kotuy region of ...

Meteorology and geography, more than biological traits, drive variation in frog phenology across decades

Ecology, Volume 107, Issue 5, May 2026.
Abstract The fate of a species is a function of interacting environmental and biological processes. Disentangling the roles and interactions of such processes can elucidate the breadth of possible responses to global change, for instance, the potential for phenotypic plasticity or trait evolution to rescue populations from climate change.

Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, Volume 46, Issue 6, May 2026.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Bound States in the Continuum and Fano Resonances in the Dirac Cone Spectrum

, 2019
We consider light scattering by two dimensional arrays of high-index dielectric spheres arranged into the triangular lattice. It is demonstrated that in the case a triple degeneracy of resonant leaky modes in the Gamma-point the scattering spectra ...
