Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
2003
In a factorial field experiment we increased the temperature (Open Top Chambers) and nutrients (nitrogen, phosphorus, and potassium [NPK]) to simulate predicted future climate changes and studied the growth response of the acrocarpous bryophyte Pohlia wahlenbergii (Bryaceae) in a wet snowbed environment. The species shows a positive growth-length response to added nutrients and increased temperature. The stronger response to nutrients indicates a strong limitation of nutrients in the snowbed environment. There was an immediate response to nutrient treatment, whereas the temperature response was delayed. The growth response shows a clear interaction between temperature and nutrients. The imm…
Revelations for global change and conservation: determining European fungal species’ patterns via a large-scale fruit body ‘meta-database’
2018
PRESENTATION:The driving forces to the geographical structuring of fungi remain notably irresolute, despite well documented trends for a variety of plant and animal groups. This information is critical to planning and mitigating potentially negative consequences of global change, and especially related to conservation. We identified the major geographical and environmental gradients structuring fungal assemblages for two main nutritional modes, saprotrophic and ectomycorrhizal fungi, through the use of 4.9 million European fungal fruit body observations. For both fungal nutritional modes, mean annual temperature correlated most with the first gradient identified that structured assemblages.…
