The middle to Late Holocene environment on the Iturup Island (Kurils, North Western Pacific) [PDF]

, 2023
The Kuril Islands stretch southwest from Kamchatka, Russia, to Hokkaido, Japan and separate the Sea of Okhotsk from the northern Pacific Ocean. A series of transgressions and regressions linked to variations in climatically affected global ice volume are

Phylogenetic lineages and the role of hybridization as driving force of evolution in grass supertribe Poodae

TAXON, Volume 69, Issue 2, Page 234-277, April 2020., 2020
Abstract To investigate the evolutionary diversification and morphological evolution of grass supertribe Poodae (subfam. Pooideae, Poaceae) we conducted a comprehensive molecular phylogenetic analysis including representatives from most of its accepted genera.

Comparative characteristics for producers of pink salmon Oncorhynchus gorbuschain the basin of Lake Sopochnoe

Известия ТИНРО, 2023
Pink salmon spawners in the channel connecting Lake Sopochnoe (Iturup Island) with the sea are investigated. The samples were collected in July-August, 2016. The males dominated significantly during entire spawning run.

Vetrovoy isthmus of iturup island – holocene strait

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Explosive volcanism is equally important as the features of neotectonic and modern movements for the development of the Kurile Islands coast, as it led to the afflux of hundreds of millions of cubic meters of pumisopyroclastic material and tephra into the wave processing zone of coastal zones of the Pleistocene-Holocene ...

SNP-based discrimination of pink salmon stocks of the Sea of Okhotsk basin: resolution of the approach and possible ways to increase it

Frontiers in Marine Science, 2023
In this work, we studied the intraspecific polymorphism of pink salmon, Oncorhynchus gorbuscha (Walbaum, 1792), the least genetically explored species among Pacific salmon and one of the central fisheries objects in the Russian Far East.

Present‐day sympatry belies the evolutionary origin of a high‐order polyploid

New Phytologist, Volume 216, Issue 1, Page 279-290, October 2017., 2017
Summary Disentangling the evolutionary histories of polyploids, especially those with high ploidies, can reveal fundamental processes in speciation. Despite occurring frequently during evolution, the origins of many extant polyploid plant species remain largely unknown. By integrating linkage mapping, polyploid phylogeny and sex‐determining region (SDR)

The Structure of the Volcanic Lake in the Urbich Caldera (Iturup Island, the Kuril Islands)

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The article presents and analyzes the original data on the morphological features and the current state of a previously unexplored volcanic lake Krasivoe located in the Urbich caldera (the Southern Kuriles). The bathymetric scheme and echolocation profiles obtained with using of modern technique of digital bathymetric survey ...
