Climate change forces species to adapt rapidly to avoid extinction. To directly observe rapid adaptation and extinction, we conducted synchronized evolution experiments with Arabidopsis thaliana in 30 locations across Western Europe, the Mediterranean, the Levant, and North America. Whole-genome pooled sequencing of ~70,000 surviving plants revealed repeatable allele frequency shifts in similar climates but divergent shifts across contrasting ones, indicating evolutionary adaptation. We identified genetic variants linked to climate adaptation, including genes involved in processes ranging from thermal-stress sensing to spring-flowering timing. Evolutionary trends were often predictable, but variable, across environments. In warmer climates, evolutionary predictability correlated with population survival over 5 years, whereas erratic changes preceded extinction. These results show that rapid climate adaptation is possible, but understanding its limits will be crucial for biodiversity forecasting.

The cassava whitefly (Bemisia tabaci) greatly constrains cassava production across Africa due to its role as a vector of viral diseases that cause substantial yield losses. Effective management of this insect pest requires detailed knowledge of its spatio-temporal distribution, however long-term datasets are scarce. Mechanistic models circumvent these long-term data needs by modelling temperature-dependent processes that govern population dynamics. Nevertheless, their application to B. tabaci remains poorly explored. Here, we developed a mechanistic model to derive a risk index (RI) for B. tabaci across Africa, focusing on Malawi. The model integrates the effects of temperature on the life stages of B. tabaci to predict temporal risk dynamics and assess climate change impacts. Validation against historical data demonstrated strong agreement, with high cosine similarity values (0.95 in 1988 and 0.96 in 1990) and high correlation coefficients (0.73 and 0.78 in 1988 and 1990, respectively), supporting its suitability as a proxy for whitefly population dynamics. Areas with temperatures between 20.2 °C and 32.5 °C are conducive to B. tabaci population increase, with suitability peaking near 27.5 °C. Cassava-growing regions in central and western Africa experience year-round higher RI values, whereas southeastern Africa experiences peak RI values from October to March. In Malawi, the lakeshore and southern regions were most vulnerable, with RI peaking in these areas during the rainy season. At continental and national scales, climate change is projected to increase RI values. These findings underscore the importance of timing pest control interventions to align with peak risk periods and highlight the utility of mechanistic models for informing region-specific whitefly management strategies.

Anaerobic digestion (AD) is a biological process where microorganisms degrade organic waste under anaerobic condition and produce biogas consisting of 50–75% methane (CH4), 25–50% carbon dioxide (CO2), and other trace gases. However, the presence of non-methane gases reduces the heating value of biogas and impurities, such as H2S, reduces its desirability. To improve the quality, biomethanation could upgrade biogas via converting CO2 using green hydrogen (H2) into additional CH4 by the action of methanogenic archaea. Despite this potential, the presence of process inhibitors like H2S and NH3-N can impact the efficiency of this environmentally friendly method. To address this challenge, the application of biofilm has emerged as a promising approach to improve system performance and stability under varying operational parameters and inhibitory conditions. For instance, a case study from a Norwegian full-scale biofilm plug flow reactor (BPFR) included in this study demonstrated the potential of biofilm-based AD in maintaining stable CH4 yield, even under a higher FOS/TAC ratio of greater than 0.4 and NH3-N concentration of 5500 ppm. Based on this foundation, this PhD study investigated the impact of H2S and NH3-N on biomethanation and the role of biofilm-based biomethanation in mitigating these effects.

Dette overvåkings- og kartleggingsprogrammet er finansiert av Mattilsynet og arbeidet er utført av Norsk institutt for bioøkonomi (NIBIO) og Mattilsynet. Formålet er å så tidlig som mulig oppdage fremmede og skadelige trelevende insektarter som måtte ankomme Norge. Beredskapsdelen av prosjektet inkluderer et lett tilgjengelig lager av feller og kjemiske lokkemidler til bruk dersom utvalgte karanteneskadegjørere skulle bli oppdaget. De ulike lokkemidlene som brukes i prosjektet tiltrekker seg biller i slektene Anoplophora og Agrilus, samt flere andre bark- og trelevende insektarter på EPPO (European and Mediterranean Plant Protection Organization) sine lister over karanteneskadegjørere. Sommeren 2025 ble fire lokkemidler testet i feller ved bruk av en fangstmetodikk etablert i 2021. Fellene var utplassert i skogområder nær åtte ulike virksomheter som var vurdert av Mattilsynet å ha forhøyet risiko for å introdusere fremmede arter. Totalt ble det fanget 5 616 trelevende insekter. Det ble ikke fanget noen karanteneskadegjørere.
