Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

To date, only adults of Zercon forsslundi have been known. According to the description of this species, it has been the first report of Zercon with clear differences in opisthonotal chaetotaxy between females and males, a unique character in the genus. At the same time, Z. forsslundi belongs to a unique group of Zercon species with dorsal setae J5 in females clearly longer than setae J1 – J4 , the latter ones being short and of similar length. Our description is the first-ever report on the full morphological ontogeny of Z. forsslundi , the mite species, the adult which is the most similar to the recently described Zercon hamaricus and to a lesser extent to Zercon polonicus . The morphological closeness of the above-mentioned species has been confirmed in immature stages. We also studied the geographic distribution of Z. forsslundi and its above-mentioned congeners with remarks on their evolutionary affinity on the background of dispersal abilities and faunal dispersal after the Last Glacial Maximum. We also report the occurrence of Z. forsslundi and Z. hamaricus in the Northern Norway for the first time. Ranges of Z. forsslundi and Z. hamaricus overlap in the area of N Norway. Also, the microenvironmental sympatry was confirmed for these taxa. We also proved the niche overlap of these two species, which is probably limited to the northern verge of Eurasia. Zercon polonicus , not present in the current Arctic fauna, probably is a post-glacial relict, inhabiting more southern mountainous areas of Europe (Carpathians and Alps).

Ethiopia faces growing environmental and energy problems because of its expanding cities, increasing dependence on biomass fuels. This study evaluated briquettes made from sawdust, coffee husk, fruit waste, flower waste and vegetable residues through different particle sizes (0.3–1 mm, 2–4 mm, 5–7 mm) and compaction pressures (5 MPa, 10 MPa) using pulped paper as a binder. The evaluation of fuel properties included density measurements, moisture content, ash content, fixed carbon, volatile matter and calorific value assessments. The combination of small sawdust particles under 10 MPa pressure produced briquettes with the highest calorific value of 20.96 MJ/kg and strong mechanical strength. The combination of small coffee husk particles under 5 MPa pressure produced briquettes with 78.05 % volatile matter and 17.62 MJ/kg calorific value. The addition of binder materials improved combustion properties and decreased the amount of volume expansion. The waste volume reduction through briquetting reached 54.8 % which demonstrates its effectiveness as a waste reduction technique. However, this study did not include combustion emissions analysis, life cycle assessment (LCA), techno-economic evaluation (TEA), or pilot-scale field validation. Hence, the reported substitution and deforestation mitigation figures were theoretical and based solely on laboratory-scale calorific equivalence. As such, broader claims regarding environmental and energy system impacts should be considered preliminary and require further verification through real-world deployment and systems-level analysis.
