Agroforestry on sloping lands: A sustainable way forward
Farming on slopes feeds nearly a billion people, but often leads to soil erosion and degradation. A new PhD thesis from the Swedish University of Agricultural Sciences (SLU) suggests intercropping trees, crops, and grasses as a sustainable solution.
Guillemots prefer predictable foraging grounds
Common guillemots tend to seek out areas where the availability of fish is stable, even if the amount is small – a strategy that may leave them vulnerable as environments change. Using sailing drones and GPS transmitters, Astrid A. Carlsen has mapped how guillemots and razorbills search for food.

The infectious load in the pig stable
The aim of the project is to evaluate different methods to measure the “infectious load” in pig stables, and use selected methods to investigate the influence of the floor structure and practises for cleaning and disinfection, on the 'infectious load'. -
Boosting the reproductive performance of Arctic charr using high-throughput sequencing technologies
The project will identify the main causes affecting male fertility and assess to which degree they explain the low reproductive performance in Arctic charr farmed in Sweden. Multiple parameters will be explored, such as age, sampling time during the spawning season, and genetics. Read more below.

Chromosome doubling helps plants find new niches, but there are hidden risks
During evolution, plants sometimes acquire an extra complete set of chromosomes. This leads to greater genetic variation and opportunities to expand in new environments. However, it may also lead to the accumulation of harmful mutations in the genome, which can be a long-term threat. -
The protein that helps seedlings straighten
Seedlings bend their tip as they grow through soil, then straighten when they reach light. Scientists from Umeå have, after years of challenging research, identified a protein that promotes this straightening by regulating cell growth through the plant hormone auxin. -
12 million SEK for unique research project: Can relocated trees save the forests of the future?
Swedish forests face major challenges as the climate changes. To prepare for the future, Formas has now awarded 12 million SEK over four years for a research project on assisted migration of tree species.

Mapping bird flu risks will prevent future outbreaks
Since 2020, bird flu has affected around twenty food-producing poultry farms in Sweden, leading to the death or culled of nearly 2.4 million poultry. -
Pests and pathogens cause devastation in nature reserves
It may be tempting to perceive damaged forests as primarily a problem for the forest owner or the industry. A factor affecting price on wood, but of limited importance to society.
