Dr Anne Oxbrough’s research in the Biology Department at Edge Hill University explores the juxtaposition between biodiversity, ecosystem functioning and resilience in response to environmental change.
Globally, we are at a tipping point; in the era of the anthropocene, human-induced modifications to natural landscapes have resulted in significant biodiversity loss. Likely driving mechanisms are habitat loss, fragmentation, climate change, pollution and invasive species. However, the effect of this biodiversity loss on ecosystem function is only beginning to be explored and the key question of how can we ensure ecosystem resilience in to the future? remains unanswered. In this research group, work focuses on determining the mechanistic link between management in agricultural and forest systems, biodiversity and ecosystem function, with the aim of adopting management approaches that promote ecosystem resilience. We use a range of taxonomic approaches across temporal and spatial scales to address these questions in field and experimental settings.
This project determines how taxonomic and functional diversity of spiders, beetles, vascular plants and bryophytes respond to changes in forest structure within a forest stand over a 20 year period through a harvest cycle in Scots pine and Sitka spruce plantation forests and will determine the resilience of these taxa to harvesting disturbances. This project is jointly funded by Edge Hill University and the Scottish Forestry Trust and co-supervised by Dr Anne Oxbrough of Edge Hill University and Dr Nadia Barsoum of Forest Research.
Spider diversity in stands of increasing tree species diversity. (2018-)
This project explores the influence of increasing tree species diversity and irrigation treatments on spider taxonomic diversity and guild structure. It uses spiders collected at the Orphee project, a long-term tree diversity experiment and part of the TREEDIVNET global network of sites. This project is a collaboration with Dr Hervé Jactel of INRA, France.
The impact of grazing on upland biodiversity (2013-2017).
Calcareous grassland is one of the most species rich and diverse habitats in Europe. In recent years conservation organisations have altered grazing practices to conserve the characteristic vegetation of these internationally important habitats. This project examined the impacts of contrasting grazing practices on spiders, carabid beetles and plants in upland calcareous grasslands. Many of the results of this project provided the first evidence of effects of contrasting grazing management in upland calcareous grassland.
This project works closely with land managers and owners to translate scientific research evidence base to workable recommendations for upland calcareous grassland grazing management. It is the first to have invertebrates, and not plants, as the focus.
Recommendations include prescriptions for grazing regimes over varying spatial and temporal scales.
UK carrion beetle diversity.(2016-)
This project is a novel large-scale investigation of the ecology and phenology of carrion beetles in forested and open habitats.
It takes a broad geographical approach across a growing season to explore habitat preferences of species from the Silphidae and Leiodidae families.
