Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

open access: yesIbis, Volume 168, Issue 4, Page 1230-1240, October 2026.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

A postulate for tiger recovery: the case of the Caspian Tiger

open access: yesJournal of Threatened Taxa, 2012
Recent genetic analysis has shown that the extinct Caspian Tiger (P. t. virgata) and the living Amur Tigers (P. t. altaica) of the Russian Far East are actually taxonomically synonymous and that Caspian and Amur groups historically formed a single ...

A Genetic Risk Variant Associated With the Risk of Primary Biliary Cholangitis Is Inherited From Neanderthals

open access: yesLiver International, Volume 46, Issue 10, October 2026.
ABSTRACT Background Primary Biliary Cholangitis (PBC) is an autoimmune cholangiopathy with polygenic architecture and unknown aetiology. Evidence links Neanderthal‐derived genetic variants to autoimmune conditions; however, their contribution to PBC susceptibility remains unexplored.

Insights into the effects of reproductive phase thermal stress on physiology and yield‐related traits of rice cultivars

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract High temperatures lead to a significant drop in rice (Oryza sativa L.) productivity worldwide, especially during the reproductive stage. This research was piloted to evaluate 10 promising rice cultivars for their ability to withstand high‐temperature stress (HS) during the reproductive phase and to assess the impact on physiology and yield ...

FORMING CASPIAN SPRAT STOCKS IN MODERN STATE OF THE SEA ECOSYSTEM

open access: yesVestnik of Astrakhan State Technical University. Series: Fishing industry, 2018
More than 50 years sprat fishing has been a leading trend in the Caspian Sea. Annual catch of sprat species (common kilka, anchovy, big-eyed kilka) reached 440.000 tons. The main fishery object was anchovy sprat. In recent decades anchovy sprat stock has decreased. Common sprat has become main fishery object.
