Article Synopsis
- Avian influenza (AI) poses a global threat to birds and mammals, resulting in significant economic losses in both commercial and backyard poultry settings, with over 8,500 cases reported in 2022.
- Outbreaks have been particularly prevalent in the Russian Federation since 2020, driven largely by wild migratory birds that act as reservoirs for the virus and can facilitate the emergence of new, dangerous variants.
- Monitoring studies in 2021 in the Samara Oblast detected a highly pathogenic A/H5N1 strain in wild birds, revealing connections to other global isolates and underscoring the urgent need for better information sharing and comprehensive research on virus spread.
, the causative agent of listeriosis, is amongst the major food-borne pathogens in the world that affect mammal species, including humans. This microorganism has been associated with both sporadic episodes and large outbreaks of human listeriosis worldwide, with high mortality rates. In this study, the main sequence types (STs) and clonal complexes (CCs) were investigated in all of the 13 strains originating from different sources in the Republic of Serbia in 2004-2019 and that were available in the BIGSdb-Lm database.

- - Species rely on environmental cues, like degree-days, to time their phenological events and exhibit varying responses based on their location and the season.
- - The study analyzed data from 91 taxa across 472 sites in the former Soviet Union, finding that spring phenological events advance more consistently with temperature cues (cogradient variation), while autumn events are less responsive (countergradient variation).
- - Despite some local adaptations, phenological events generally do not keep pace with environmental cues, particularly lagging further in earlier years, suggesting differing impacts of climate change on spring and autumn species responses.

View Article and Find Full Text PDFWe present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi.
