A novel negative-sense single-stranded RNA virus showing genetic similarity to viruses of the genus Rubodvirus has been found in raspberry plants in the Czech Republic and has tentatively been named raspberry rubodvirus 1 (RaRV1). Phylogenetic analysis confirmed its clustering within the group, albeit distantly related to other members. A screening of 679 plant and 168 arthropod samples from the Czech Republic and Norway revealed RaRV1 in 10 raspberry shrubs, one batch of Aphis idaei, and one individual of Orius minutus. Furthermore, a distinct isolate of this virus was found, sharing 95% amino acid identity in both the full nucleoprotein and partial sequence of the RNA-dependent RNA polymerase gene sequences, meeting the species demarcation criteria. This discovery marks the first reported instance of a rubodvirus infecting raspberry plants. Although transmission experiments under experimental conditions were unsuccessful, positive detection of the virus in some insects suggests their potential role as vectors for the virus.

Since 2005, the population of the trans-border brown bear (Ursus arctos) in Trilateral Park Pasvik-Inari (Norway-Finland-Russia) has been monitored by using genetic analyses of hair and faeces collected randomly in the field. A more systematic method using hair traps every fourth year was initiated in 2007 to collect brown bear hairs for genetic analysis. The method consisted of 56 hair traps in Norway, Finland and Russia in a 5 x 5 km2 grid cell system (ca 1400 km2). The project was repeated in 2011, 2015, 2019 and now in 2023. This season’s sampling was carried out in Pasvik (Norway) - Inari (Finland) area (43 squares, 1075 km2), using the same methodology as in the previous studies. A total of 97 samples were collected, where 45 samples came from Finland and 52 samples from Norway. In the bear specific analysis, 71 (73 %) of the 97 hair samples were positive. A complete DNA profile could be determined for 63 of the positive samples. In total, 22 different bear individuals were detected (10 females and 12 males). Of these 22 bears, 12 bears were detected in previous years, while 10 were previously unknown bears. In total, 13 bears were detected in Finland and 11 bears in Norway. This year’s sampling has the 2nd highest success rate in number of individuals detected per grid square, with 0,51 individual per grid square compared to 0,81 individuals in 2019 (highest success rate), 0,49 in 2015, 0,35 in 2011 and 0,42 in 2009. Our results showed that even with a smaller study area, the hair trap project every 4th year provides valuable information on the brown bear individuals in addition to a random sampling in the field (The National Monitoring Program for brown bears in Norway).

The Norwegian monitoring programme for agricultural landscapes has been running for 25 years, collecting data on status and change in agricultural landscapes. The programme is based on mapping of a thousand 1 x 1km squares from aerial photographs, with field work to record birds and plants at around 10 % of the squares. In 2021, the programme introduced field recording of butterflies and bumblebees along a 1 km transect at ten monitoring squares. In spite of the low number of sites, we found a clear trend between landscape spatial structure and number of pollinators. Both the number of individuals and number of species increased with increasing landscape heterogeneity. This mirrored patterns that have been detected in the monitoring of farmland birds. Much is known about how to improve farming landscapes for pollinators. In Norway, agri-environmental subsides are available to encourage the management of flowery pollinator zones adjacent to arable land. First, farmers received payment to sow nectar-rich plants such as the non-native Phacelia tanacetifolia in field margins. Then higher subsidy rates were introduced for using seed mixes of regional plant species. The latest development is payment for managing zones adjacent to the crop, typically woodland edges. This saves agricultural soil for food production, whilst expanding the role of farmers in contributing to pollinator-friendly landscapes.
