On the Origin of the Tingidae (Insecta, Heteroptera)
ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

In Search of Emerging Polities: Thematic Agendas of Selected European Cross-Border Cooperation Structures [PDF]
The objective of this paper is to find several answers by investigating the extent to which the cross-border cooperation structures (CBCS) act as de facto emerging polities.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

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 ...

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

Biodiversity and socio-environmental problems of the south-eastern Baltic coastal zone
AbstractThe diversity of life occurs at several hierarchical levels of biological organisation, including the biotope (habitats) diversity. The knowledge of the coastal habitat diversity and its sensitivity to the anthropogenic impact is one of the most important preconditions for the sustainable use and development of the coastal regions.

Mesozooplankton assemblages differed significantly both between and within Baltic Sea bays, driven mainly by local salinity and temperature gradients. Distinct communities occurred over distances of less than 1 km, demonstrating strong fine‐scale spatial variability.
