The lecture provides practical guidance on research proposal development and international funding opportunities, with a particular focus on Horizon Europe. It covers how to identify suitable funding calls, understand call requirements and eligibility, develop competitive research ideas, formulate clear and measurable objectives, and design a sound research methodology. It also explains the main components of a Horizon Europe proposal, including Part A and Part B, and provides step-by-step guidance on writing the Excellence, Impact, and Implementation sections. The lecture further addresses international partnership and consortium building, work packages, deliverables, milestones, risks, staff effort, budget allocation, dissemination, exploitation, communication, and proposal evaluation criteria. Real and illustrative project examples, including collaborations between Norwegian and African universities, are used to connect proposal-writing principles with practical research funding experience.

Abstract
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are key long-chain omega-3 fatty acids in fish nutrition, but their differential effects on Atlantic salmon under unpredictable chronic stress (UCS) remain unclear. This study compared hepatic responses to DHA- and EPA-rich diets under unstressed and UCS conditions. Atlantic salmon post-smolts were fed a low-EPA+DHA, DHA-rich, or EPA-rich diet for 10 weeks, followed by 3 weeks of UCS. Liver transcriptomes were analyzed by RNA sequencing, and selected genes were validated by quantitative reverse transcription PCR. Growth did not differ among dietary groups. Under unstressed conditions, the DHA-rich diet induced more differentially expressed genes than the EPA-rich diet (67 vs. 29) and affected pathways related to fatty acid metabolism, autophagy, cholesterol homeostasis, and antioxidant defense. After UCS, the EPA-rich diet induced a broader hepatic transcriptional response than the DHA-rich diet (205 vs. 57 differentially expressed genes), with only 12 genes shared between the two comparisons. Both diets affected fatty acid- and steroid-biosynthesis-related pathways, while gene-level responses were diet-specific. These findings reveal distinct, stress-dependent hepatic responses to dietary DHA and EPA and may inform future optimization of their nutritional provision in Atlantic salmon production.

Recovering and recycling agricultural mulch films can be costly and difficult because the plastics are often contaminated with soil, plant and pesticide residues. Biodegradable mulch films offer a potential alternative, but what happens when they are left in the field? Using examples from Norwegian field and laboratory studies, this presentation will explore how biodegradable mulch films degrade in soil, how they interact with pesticides, and what this means for the use of agricultural plastics in a circular economy. This session will provide a basis for discussion among project partners on experiences with biodegradable and conventional mulch films across different agricultural, environmental and waste-management contexts.

Palm oil is a commonly used dietary fat source in European dairy beef production, but concerns about deforestation associated with its cultivation have stimulated interest in alternative fat sources with the potential to mitigate enteric methane emissions and reduce the carbon footprint of beef production. Oils richer in polyunsaturated fatty acids have been suggested as promising alternatives due to their potential to modify rumen fermentation. The present study aimed to evaluate the dietary substitution of palm oil with sunflower oil, which is rich in polyunsaturated fatty acids, on animal performance, enteric methane emissions, and environmental footprint. Ninety-four crossbred bulls (399 ± 9.3 kg BW and 271 ± 4.0 days of age) were allocated into six pens and fed concentrate and straw separately, both ad libitum. Treatments were based on the fat source of the concentrates: (1) CTR (n = 46), with 3.50% palm oil on a weight basis as control; and (2) SUN (n = 48), with 3.50% sunflower oil. The study lasted 42 days. Individual feed intake was recorded daily. Bulls were weighed every two weeks. Enteric emissions (CH4, CO2, and O2) were recorded daily with a “sniffer” measurement system installed in each concentrate feeder per pen. Daily CH4 production (L/day) was estimated based on Madsen et al. (2010). Data were analysed using a mixed-effects model. The environmental impact of the two diets was evaluated with the life cycle assessment methodology. No differences in average daily weight gain were observed between dietary oil sources (1.83 vs 1.85 ± 0.141 kg/day, P = 0.87; CTR vs SUN, respectively) and concentrate intake (7.48 vs 7.48 ± 0.420 kg DM/day, P = 1.00; CTR vs SUN). A treatment × period interaction (P < 0.05) with no clear pattern was observed in most of the enteric CH4 emissions data. Nevertheless, in the first 14 days of the study, enteric CH4 emission expressed relative to concentrate intake was lower (P < 0.01) in SUN bulls than in CTR bulls. Carbon footprint was lower in SUN concentrate (0.75 kg CO2 eq/kg concentrate feed) compared with the CTR concentrate (0.89 kg CO2 eq/kg concentrate feed). Thus, the substitution of palm oil with sunflower oil reduces enteric methane emissions expressed relative to concentrate intake during the first days after dietary substitution without detrimental effects on animal performance and reduces the carbon footprint of the dietary concentrate, which is the main contributor to meat’s carbon footprint.
