1. 1. The function of seasonal habitat shifts in two congeneric mayflies in a boreal river

   Författare :Olle Söderström; Umeå universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Habitat utilization; diel activity; orientation; predation; life-history; temperature; food quality; mayflies; Parameletus chelifer; Parameletus minor;

   Sammanfattning : Unregulated North Swedish rivers show large seasonal variations in their physical characteristics. During winter the whole littoral zone freezes solid, and in spring the water flow increases rapidly and the same areas become flooded. The two mayflies Parameletus chelifer and P. minor are common in the North Swedish river Vindelälven. LÄS MER

   Sammanfattning : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. LÄS MER
