    Author : Jan-Olof Seyer; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ampularia; Littorina; Strombus; evolution; visual ecology; summation; convergence; optic nerve; resolution; sensitivity; optics; eye; gastropod; prosobranch; Animal anatomy; animal morphology; Djurs anatomi och morfologi;

    Abstract : Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp.

  4. 2. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Author : Shiyong Yu; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Abstract : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kartografi; klimatologi; Geofysik; fysisk oceanografi; physical oceanography; meteorology; Sedimentologi; Stratigrafi; Stratigraphy; Baltic Sea; geokemi; Petrologi; mineralogi; geochemistry; mineralogy; Petrology; greigite; mineral magnetics; sea-level changes; Holocene; Littorina transgression; geomorphology; pedology; cartography; climatology; meteorologi; Geophysics; Sedimentology; Optically Stimulated Luminescence OSL ; Fysisk geografi; geomorfologi; marklära; Physical geography;

    Abstract : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. READ MORE
