Om bogen

Bogen indeholder kongresbidrag fra 19th European Colloquium of Arachnology, som blev afholdt på Aarhus Universitet 17.-22. juli 2000 på vegne af European Society of Arachnology (Paris). Den er tilegnet den danske edderkoppeforsker Edwin Nørgaard.

Bogen indeholder dels nogle oversigtsartikler vedrørende edderkoppeadfærds neurobiologi, seksuel selektion, sædkonkurrence og systematik hos edderkopper samt skorpioners livshistorie, skrevet af inviterede specialister; dels indeholder den en lang række originale forskningsartikler, hovedsageligt om edderkopper, inden for et bredt spektrum af forskningsfelter: økologi og adfærd; edderkoppespind og silke; indsamlingsmetoder; faunistik og systematik.

Flere artikler analyserer edderkoppefaunaens "naturværdi" i forskellige typer habitater.
