This research explores the diversity of beetle species in Swedish oak forests through the innovative use of biodiversity pheromones. The project aims to assess how environmental degradation influenced by human activities affects beetle populations across southern Sweden. By...
Our investigation explores temporal growth patterns in Swedish Quercus species by analysing dendrochronological core samples from various locations. This study aims to determine if there have been any significant changes in the growth rates of oak trees due to climate change. We...
In this project, we study the differential distribution and infestation rates of two cryptic species, Acrocercops brongniardellus and Acrocercops andreneli, on oak trees. Using COI barcoding, we delve into the complexities of species co-occurrence and the diversity of...
This research project investigates the genetic diversity and potential local adaptations within oak populations, explicitly focusing on Quercus robur at the northern limits of their range. By analysing patterns of genetic differentiation and gene flow, the study aims to...
This project investigates the intricate timing of life cycle events (phenology) and their alignment with food web interactions in oak forests across Sweden. We examine how the timing of oak budburst and senescence influences, and is influenced by, the activity patterns of...
Study on how the age of oak forests influences biodiversity, particularly focusing on species richness and composition across six key groups: insects, arachnids, springtails, lichens, bryophytes, and vascular plants. Despite high diversity across all forest ages, significant...
This project seeks to understand how soil nutrient levels, specifically nitrogen as indicated by the Ellenberg Nitrogen Index, affect the growth rates of oak species across Sweden. We use dendrochronological methods to elucidate the relationship between nitrogen availability and...
Study involving three experimental oak stands established in 1995 at Askeby, Tånnö, and Vibyholm. This project evaluates the incidence of reproductive oaks, considering species variations (Skogsek, Bergek, and hybrids), geographical impacts (latitude and climate), genetic...
We address key challenges in metabarcoding methodologies used to assess the biodiversity of terrestrial arthropods. These arthropods are vital to ecosystem health but are often misestimated due to taxonomic complexities. We refine metabarcoding techniques by evaluating size...
Phytopathogens and phytophagous insects coexist within plant communities, often sharing host plants. This study examines how differences in pathogen infection rates influence the species richness, prevalence, and community structure of phytophagous insects at various...
This project investigates the latitudinal gradients of biodiversity and ecosystem services in Sweden’s protected and non-protected oak forest areas to inform climate-smart conservation strategies. By comparing plant and arthropod diversity and oak tree productivity across a...
The project involves a study of growth patterns and provenance in oaks, using data from a 25-year-long common garden experiment. Initiated in 1995, the study translocated over 6000 acorns from various locations across Sweden to three different stands. These stands, situated...
This study assesses the success of reintroducing the Great Capricorn beetle, Cerambyx cerdo, by utilising radio telemetry within the Tromtö Nature Reserve in Sweden. By analysing the beetle’s movement patterns and habitat utilisation, especially at the northernmost margin of...
This study investigates the factors influencing acorn size across native and non-native oak species in Sweden. It explores how environmental conditions and biological interactions affect oak reproductive strategies. The findings aim to inform conservation practices and enhance...
Research from Sweden reveals that old trees continue to grow and sequester carbon at high rates, challenging previous assumptions about their growth decline. This finding suggests that preserving old trees in forests can significantly enhance carbon capture and aid in combating...
Our research utilises RAD-sequencing to reveal how genetic diversity and structure have fluctuated over centuries within three distinct sites. We assess the impacts of environmental changes and human influence on these long-lived species by comparing genetic data across multiple...
Study focused on the invertebrate biodiversity residing on the trunks of oak trees throughout Sweden. Our research explores the variety of invertebrate species, their abundance, and the intricate phenological patterns across different latitudinal gradients. By combining...
This project investigates the diversity and ecological dynamics of yeast species on oak bark. Collecting and analysing samples from various oak trees, we aim to uncover how these microorganisms evolve and interact within their unique ecological niches. This study, conducted in...
