Urban ecosystem services research in Russia: Systematic review on the state of the art.

Research on urban ecosystem services (ES) covers many regions globally, yet significant gaps remain in several areas, including Russia. Furthermore, the number of publications on Russian ES is still very low, and most of them focus on ES assessment on the national level which results in an incomplete understanding of ES provision in Russian cities. To fill this gap, 197 publications on urban ES have been systematically reviewed.

Disjunct habitat of cryptic Terebellides (Annelida, Trichobranchidae) species shows a phylogenetic link between polychaetes from the White and the North Seas.

Understanding the distribution and biodiversity of marine species is crucial for developing effective conservation strategies and maintaining the health of global ecosystems. Advancements in molecular data utilization have significantly improved our understanding of biodiversity within the genus Terebellides. In this study, we conducted a phylogenetic analysis on polychaete samples from the Kandalaksha Bay, White Sea, revealing their affiliation with a putative undescribed species of the genus Terebellides found in two locations of the North Sea.

Memory reacquisition deficit: Chicks fail to relearn pharmacologically disrupted associative response.

It is generally assumed that if memory is disrupted by pharmacological inhibitors during its consolidation, it can be later acquired afresh. In our experiments, we trained day-old chicks in a one-trial passive avoidance task and interfered with memory formation using protein synthesis inhibitor anisomycin or NMDA receptor antagonist MK-801. Second training was then given to amnestic animals with either the same conditioning stimulus (retraining) or a new one (novel training).

A mega-cryptic species complex hidden among one of the most common annelids in the North East Atlantic.

We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structure of North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabiting continental shelf and slope sediments. We demonstrate the presence of more than 25 species of which only seven are formally described. Species boundaries are determined with molecular data using a broad range of analytical methods.
