On the Origin of the Tingidae (Insecta, Heteroptera)

open access: yesZoologica Scripta, EarlyView.
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 ...

Cooperation between the fishery sector and science: CTD probe measurements during fishing catches on the feeding grounds of herring (Culpea harengus) and sprat (Sprattus sprattus) in the south-eastern part of the Baltic Sea

open access: yesOceanologia
282 CTD probe measurements were analysed for the parameters of temperature, salinity, depth and oxygen saturation of the water column. These measurements were taken during commercial pelagic fishing for herring (Clupea harengus) and sprat (Sprattus ...

In Search of Emerging Polities: Thematic Agendas of Selected European Cross-Border Cooperation Structures [PDF]

open access: yesRomanian Journal of European Affairs, 2016
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

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.
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

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
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 ...

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 ...

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

open access: yesIbis, Volume 168, Issue 4, Page 1731-1738, October 2026.
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

open access: yesLimnologica, 1999
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.

Between and Within Bay Differences in Mesozooplankton Assemblages in the Central and Eastern Baltic Sea: An Exploratory Study

open access: yesBiological Diversity, Volume 3, Issue 3, Page 149-157, September 2026.
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.
