  1. 31. Superior Underwater Vision in Humans

    Författare :Anna Gislén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; taxonomy; zoogeography; Zoologisk systematik; djurgeografi; Systematic zoology; contrast sensitivity; spatial vision; Accommodation; pupil;

    Sammanfattning : Amphibious vision is accomplished in many animals by special optical and physiological adaptations in the eyes. However, human eyes are considered to be adapted to a life in air since our curved outer cornea – which is used to refract more than two-thirds of the incoming light on land – becomes useless underwater.

  2. 32. Gall induction in gall wasps (Cynipidae s. lat.) : Insights from comparative genomics

    Författare :Erik Gobbo; Fredrik Ronquist; Scott Egan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gall induction; comparative genomics; evolution; selection analysis; microbiome; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Cynipidae are a family of wasps (Hymenoptera), whose larval stages develop inside plant galls, that is, abnormal plant structures formed in response to the presence of foreign organisms. Most cynipids are gall inducers and are often capable of notable levels of host manipulation. LÄS MER

  3. 33. Charting biodiversity : Scuttle flies and other poorly known insects in Sweden

    Författare :Sibylle Häggqvist; Fredrik Ronquist; Jeff Skevinton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Biodiversity has fascinated people in all times. We as a species are part of the global ecosystem and our survival depends on many other species around us. Charting biodiversity, however, has proven more difficult than one could imagine. LÄS MER

  4. 34. Charting Insect Diversity

    Författare :Dave Karlsson; Fredrik Ronquist; Torbjørn Ekrem; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; insect faunas; biological inventories; citizen science; DNA barcoding; morphotype barcoding; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Background: Despite Sweden's rich legacy in entomology, a significant portion of its insect fauna remains poorly studied. Addressing this and other biodiversity knowledge gaps, the Swedish government unveiled the Swedish Taxonomy Initiative (STI) in 2002, with the ambitious goal of documenting and scientifically describing all multicellular species in the country.

  5. 35. A phylogenetic analysis of rasborin fishes (Teleostei, Cyprinidae)

    Författare :Te-Yu Liao; Sven Kullander; Paul Skelton; Stockholms universitet; []
    Nyckelord :Rasbora; Chedrina; Danionina; Danionini; Rasborini; Danioninae; Opsariichthyinae; Cyprinidae; Cypriniformes; phylogeny; systematics; Africa; Asia; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : The Danioninae (sensu lato) were until recently considered to be a paraphyletic group, comprising about 200 species and distributed over Africa and southern and eastern Asia. There was no morphological diagnosis for the Danioninae, and also the composition of the subfamily, and the interrelationships of included genera have been contentious. LÄS MER
