Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

THE MIOCENE AND DEVONIAN MAGMATISM AT THE JUNCTION BETWEEN THE TUVA-MONGOLIAN MASSIF AND SIBERIAN CRATON: COMMON COMPONENT OF MANTLE SOURCES AND ITS ORIGIN

Геодинамика и тектонофизика, 2015
Devonian dikes of the Urik-Belaya and Shagayte-Gol-Urik zones and Miocene lavas of the Urik volcanic field are spatially associated with each other at the structural junction between the Neoproterozoic Tuva-Mongolian massif and Siberian craton.

Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

PETRO- AND PALEOMAGNETIC STUDIES OF BASALTS OF THE UPPER DEVONIAN APPAINSKAYA SUITE (WESTERN YAKUTIA)

Геодинамика и тектонофизика, 2016
Introduction. One of the main tasks of paleomagnetic studies is to obtain a framework of reference poles for calculating the kinematic characteristics of lithospheric taxones as a basis for geodynamic reconstructions.
