Plagioclasites from chromite-bearing ultramafic rocks of the Rai-Iz massif
Литосфера, 2016 The corundum-bearing and without-corundum plagioclasites from chromite-bearing ultramafic rocks of Rai-Iz massif were studied. Chemical composition of the rock-forming minerals and rock geochemical characteristics was determined.

Gut microbiota as a trigger of accelerated directional adaptive evolution. Acquisition of herbivory in the context of extracellular vesicles, microRNAs and inter-kingdom crosstalk [PDF]
, 2017 According to a traditional view, the specific diet in vertebrates is one of the key factors structuring the composition of the gut microbiota. In this interpretation, the microbiota assumes a subordinate position, where the larger host shapes, through ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Ecosphere, Volume 17, Issue 4, April 2026.Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...

Geochemical Disequilibrium at the Brittle‐Ductile Transition
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...
