I 2014 ble den offentlige forvaltningen av reindriften omorganisert. Områdestyrene ble avviklet og oppgavene overfør til Fylkesmannen. Områdekontorene ble samtidig en del av fylkesmannsembetene. Dette har gitt økt effektivitet i behandling av plansaker. Forvaltningsstrukturen fremstår nå som tydeligere for kommunene og annen offentlig virksomhet, men som mindre tydelig for reindriftsnæringa. Omorganiseringen ser også ut til å ha gitt den offentlige forvaltningen av reindriften økt legitimitet i samfunnet for øvrig. Det er imidlertid utfordringer knyttet til å opprettholde dialog med reindriftsnæringa og sikre medvirkning i forvaltningsprosessene.....

Reindeer-train-collisions (RTC) are a challenge for Norwegian society and the northern Norwegian train company Bane NOR with regard to animal welfare, wildlife ecology, animal husbandry, reindeer herding and the working environment for train drivers and employees of Bane NOR. On behalf of Bane NOR the Norwegian Institute of Bioeconomy Research (NIBIO) investigated putative technological solutions to improve RTCs. The study is a result of literature research, interviews with Bane NOR employees, reindeer herders, researchers, companies and road administration project leaders and an analysis of Bane NOR´s own database of animal-train-collisions. The RTC records of the last 11 years (jan 2008 – dec 2018) revealed that prioritizing preventive measures against collisions with female reindeer along the Saltfjellet region during winter, especially during the Arctic night, are most promising. This also happens to be the most damaging time of the year for reindeer herders as they struggle to find damaged animals in the dark. Expensive and timeconsuming search efforts are a major concern with regard to animal welfare. Additionally, damaged animals are often – if at all – found long after the accident and can not be brought into Connection with a specific RTC, i.e. the herders can not claim monetary compensation…….

Pasteuria spp. belong to a group of genetically diverse endospore-forming bacteria (phylum: Firmicutes) that are known to parasitize plant-parasitic nematodes and water fleas (Daphnia spp.). Collagen-like fibres form the nap on the surface of endospores and the genes encoding these sequences have been hypothesised to be involved in the adhesion of the endospores of Pasteuria spp. to their hosts. We report a group of 17 unique collagen-like genes putatively encoded by Pasteuria penetrans (strain: Res148) that formed five different phylogenetic clusters and suggest that collagen-like proteins are an important source of genetic diversity in animal pathogenic Firmicutes including Pasteuria. Additionally, and unexpectedly, we identified a putative collagen-like sequence which had a very different sequence structure to the other collagen-like proteins but was similar to the protein sequences in Megaviruses that are involved in host-parasite interactions. We, therefore, suggest that these diverse endospore surface proteins in Pasteuria are involved in biological functions, such as cellular adhesion; however, they are not of monophyletic origin and were possibly obtained de novo by mutation or possibly through selection acting upon several historic horizontal gene transfer events.

The blacktip shark Carcharhinus limbatus is a cosmopolitan species found in warm-temperate, subtropical and tropical waters around the world. The research here aimed to assess whether multiple paternity exists in South African C. limbatus and to confirm phylogeographic patterns previously observed within the species. A minimum and maximum frequency of 50% and 71% multiple paternity, respectively, were observed in 14 litters genotyped with five microsatellite markers. Based on the mitochondrial control region, relatively high nucleotide and haplotype diversity characterised the South African sampling population, and pairwise φST values indicated that it significantly differed from the populations of the Pacific and the western Atlantic oceans. The haplotype network showed that the South African samples were grouped closely with the Australian, Indo-Pacific and West African C. limbatus samples, which is suggestive of an Indo-Pacific origin for this population. This study is the first to report multiple paternity in this species. Furthermore, the results reveal that C. limbatus from South Africa is genetically diverse and phylogeographically distinct from most other C. limbatus populations.
