21. Macroinvertebrate sampling in hydropeaking rivers : Testing Hester-Dendy samplers in a laboratory environment using different flow conditions
Kandidat-uppsats, Karlstads universitet/Avdelningen för biologiSammanfattning : Degraded rivers and streams caused by disturbances have created a need for reliable tools to assess the ecological status of such ecosystems. Numerous methods and programs have been developed to assess ecological status using biological indicators, benthic macroinvertebrates are the most commonly used biotic indicator. LÄS MER
22. Plant phenology and climate change : possible effect on the onset of various wild plant species first flowering day in the UK
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The IPCC states that the planet is significantly warming due to effects of climate change. This warming effect has consequences for phenological events. Many species cannot track rapid climate change, resulting in phenological mismatches. This study looks at an extreme weather event and the longer-term effects of climate change. LÄS MER

24. Survival Analysis Using Time-Frequency Analysis of Heart Rate Variability During Exercise
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Heart rate variability as an indicator of increased morbidity has been established in previous studies. It is defined by different frequency bands, corresponding to different biological mechanisms. This thesis aims to study heart rate variability indices in the time-frequency domain through extraction from the UK Biobank dataset. LÄS MER
25. Assessment of freshwater ecosystem services : with a case study in river Arbogaån
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : Humans are dependent on a large variety of services that come from the eco-systems around us. Some of these ecosystem services are provided by rivers and lakes and include for example drinking water, water for irrigation and industry, flood control, climate regulation, and recreation. LÄS MER
