    Sammanfattning : Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae The frequencies of females, hermaphrodites and partially male-sterile (PMS) genets of Glechoma hederacea were estimated in natural populations in S Sweden. The frequency of females and PMS genets in natural populations varied from 0 to 100%. LÄS MER

    Sammanfattning : In 2019, Sweden implemented legislative changes to renegotiate hydropower permits to both consider environmental rehabilitation and to ensure national supply of hydropower. This means that efforts for environmental rehabilitation of the 2,000 hydropower plants in Sweden need to be considered. LÄS MER

  7. 5. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

    Författare :Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []

    Sammanfattning : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. LÄS MER
