1. Epiphytic lichen responses to nitrogen deposition
Sammanfattning : Nitrogen (N) deposition has increased globally over the last 150 years and further increase is predicted for the future. Nitrogen is an important nutrient for lichens, involved in many processes in both photobiont and mycobiont. However, N can be a stressor, causing many lichens and lichen communities to disappear with increased deposition. LÄS MER
2. In vitro studies of natural and tumor-associated immunity in patients with transitional cell carcinoma of the urinary bladder
Sammanfattning : Peripheral blood lymphocytes (PBL) from patients with transitional cell carcinoma of the urinary bladder (TCC-bladder) were studied using a SlCr-release assay for their in vitro cytotoxicity against a panel of allogeneic tissue culture cell lines of TCC-bladder and other origins. Control PBL were obtained from four different groups of donors. LÄS MER
3. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids
Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER
4. Effects of warming on the green alga Cladophora glomerata : Ecological and genetic responses
Sammanfattning : Since the beginning of the 20th century, average global surface temperature has increased ~0.7 °C and the current scenarios predict that it will continue to rise additional 2-4 °C during the 21st century. LÄS MER
5. Plankton communities in a changing world - responses to temperature, brownification and lake restoration
Sammanfattning : The effects of increasing temperatures, in light of climate change, have been a well-studied topic during the past decades. However, aquatic ecosystems are also faced with additional challenges such as increasing water colour, known as “brownification”. LÄS MER
