Forest ecosystems are an important reservoir for biodiversity in human-dominated landscapes within Central Europe, and deliver many ecosystem services. They are also a popular location for recreational activities, especially near urban areas. However, forests can also harbour threats and diseases, e.g. ticks that transmit pathogens to humans. Thus, we need to quantify the impacts of biodiversity on multiple human health risks and benefits to combine biodiversity conservation with ecosystem management that supports various health cobenefits.
To elucidate the effects that biodiversity may have for human health, additional research is needed that moves beyond single case studies with loosely defined “biodiversity” aspects to well-designed studies that allow for generalisations and evidence-based recommendations for promoting health co-benefits derived from ecosystems. Central to addressing these critical challenges are the questions of how does biodiversity matter for human health and well-being, and what interventions or polices are required to promote contact with biodiverse environments for human health and well-being. Dr. FOREST will provide mechanistic understanding on the relationship between forest biodiversity and human health and will translate these insights into solutions for management and policy.
The project makes use of existing research infrastructures for functional biodiversity studies and relies on a rigorous experimental design that allows quantification of tree diversity effects on human health. The empirical work will be done in controlled tree diversity experiments as well as in natural forests of differing diversity adopting a comparative design, located in Belgium, Germany and Poland.
Dr. FOREST will test the general hypothesis, that forest biodiversity supports mental and physical health and well-being. Our team is going to concentrate on interaction between forest tree biodiversity and quantity and quality of forest non-wood products influencing human health and wellbeing, i.e. mushrooms and medicinal herb plants.
We are going to test the following detailed hypotheses:
(1) Species richness of medicinal plants increases with increasing tree diversity, due to increased microhabitat diversity but their yield (cover) will decrease due to competition with other species.
(2) Species richness and yield of mycorrhizal mushrooms increases with increasing tree species richness, due to increased number of potential mycorrhizal partners.
(3) Amounts of biologically active substances in understorey plants are higher under monoculture canopies of specific tree species that create more stressful conditions (e.g. through resource competition).
We will survey the understorey vegetation, and collect medicinal plants for chemical analyses of active substances content. The antioxidant and anti-inflammatory activity of these substances will be studied using human neutrophils and monocytes/macrophages. We will also estimate plant fruit yield, diversity of fungi (via barcoding of soil samples) and yield of edible mushroom species three times per season during two growing seasons. The nutritional value of forest fruits and mushrooms will be used to measure level of non-wood product delivery by forests of different species composition. It will allow checking, if stand species composition influences nutritional value of these products.
The PhD student will carry field measurements and field sampling for lab analyses. She/he will carry lab work (TLC, HPLC-DAD-MS/MS analysis of active substances and biological activity of active substances in plant samples + nutritional value of plant fruits and mushroom samples) and statistical analyses of gathered data. PhD student will write publications from the project as a leading author.
